INTRODUCTION

The purpose of this course work is to acquire skills and decision microclimate conditions. Under the microclimate of industrial premises (working environment), we understand the state of the external environment of industrial premises, is determined by temperature, humidity, air movement and temperature of the surface of objects, equipment and their thermal radiation. It is characterized by a large variety of these variables and their combinations. Microclimate of industrial premises depends on the meteorological conditions of the outer atmosphere, time of day and year, production processes, and so the conditions of ventilation etc. This fact determines the extremely dynamic microclimatic conditions, but their common characteristic is largely dependent on the nature of production, processes occurring in them, and can to a certain, sometimes long period of time to remain more or less constant. On this basis, are classified in the production of existing microclimatic conditions.

One group is characterized by significant space heat release associated with the nature of the process, which exceeds the amount of heat loss (20 kcal/h, m3), regardless of the ways they come into the room (convection or radiation).This group of buildings is called hot shops. Heat is supplied to them from the hot objects and surfaces, and hot molten mass. The main factor is climate-infrared radiation from objects heated to 500- 1300 °C and more. The most studied the physical properties of the infrared radiation in the range of up to 3 nm. Starting with the 100 nm is "far" infrared region, which has a very low intensity in terrestrial conditions. Hygienic value has a range of infrared rays to 20-30 nm (NF Galanin, 1952).The higher the temperature of the body, the more heat it sends the environment by radiation.

The building - a set of premises, which are limited, within which human activity takes place. The living is accompanied by human interaction with the environment space. Proper organization of the premises and the building as a whole makes it possible to provide them safe and effective conditions of human habitation. Indoor environment, manifested in a large number of factors influence on the person called indoor climate. Among the factors of the internal environment isolate complex microclimatic conditions that most tangible physiological effects on humans. These include the thermal conditions in the room and the composition of the indoor air. Moving the air flows takes place as between rooms within a building or within a building. In addition, the building via exterior fencing comes outer or inner air is removed. The flow of air entering the room from the other rooms, carry with them an impurity gas, polluting the air of the room. Outdoor air is generally cool room.

1.1 THERMAL SHOP(HUMIDITY, TEMPERATURE ETC.)

Moving air between rooms (figure 1) due to the vertical building vertical distribution of pressure difference inside and outside the building at a difference of volume weight of external and internal air.

Figure 1 - Scheme vertical moving airflow in a building

The air flow inside the room (figure 2) occurs near the heated surfaces of heaters and process equipment and the cool surface of outdoor enclosures (so-called convective sources forming convective jet).

Figure 2 - Moving flows indoors

Man learns partly through the senses, partly conscious. Thus directly entering information about the environment in the brain correlates with the information stored in memory on the basis of previous experience. This fact testifies to the individuality of human perception of the internal microclimate premises. Environment which does not contain irritating and stimulating factors preventing physical and mental work, and the rest is called comfortable. This definition also applies to the thermal conditions and the composition of the ambient air.

Thermal conditions-currently accepted to estimate the air temperature, radiation temperature of the room, relative humidity and air mobility. The composition of air is characterized by a concentration of the carbon dioxide concentration of harmful gases, vapors, dust. Perception of air is also characterized by the ozone-ion composition and odor. These parameters are the initial building design and delivery systems of microclimate and standardized. In this definition of normative parameters comes from the desire to achieve the optimal values, those at which the fewest number of people (usually 15-30%) would be dissatisfied with them. Using optimal microclimate parameters, not all buildings can be an expedient and cost-effective. Therefore, domestic norms are widely used concept of acceptable parameters, is a reasonable boundary values at which no adverse effects on the human body.

Microclimate parameters are formed (figure 3) as a result of the impact of the external environment on the premises, process, and indoor heating-cooling (CO) and ventilation (SV) or air conditioning (SLE).

Figure 3 - Block diagram of the formation of the microclimate

External environment influences the thermal parameters of the microclimate indirectly through the building envelope (heat moisture transmitting and breathability) and internal communication between rooms (moving air currents, heat transfer).Therefore the thermal protection of the building and planning composition of the building are passive factors of formation of thermal microclimate. Technological process plays a particularly active role in shaping climate. Accompanying this process the allocation of flows of heat, moisture, gases, dust is carried directly into the room and directly affects the thermal parameters and the composition of the air. The working environment in terms of hygiene is a set of physical factors (temperature, humidity, air velocity and thermal radiation) affecting heat howling condition of the body and its heat exchange with the environment of industrial premises. The formation of climate significantly affect the process and the organization of air in the workplace, as well as the time of year and the climate of the area.

Depending on the character of the technological process the following types of climate:

1) Optimal (comfortable),which is created when you use air-conditioning systems in the electronics industry, precise instrument and others industries.

2) The heating microclimate in which the excess sensible heat - 23 W /m3 (20 kcal /hm3), created in the so-called "hot" shops.

Depending on the nature of heat gains distinguish heating microclimate radiation and convection type. Basic climate factor heating microclimate radiation type is radiant heat (infrared radiation), which are the sources of metal and glass, hot parts, flame furnace (EAF, blacksmith and glass factories), the air temperature at the same time can be up to 35-40 ° C in combination with infrared integral 1300-4000W / m2. Basic requirements. When designing and process organization and construction of the production equipment necessary to ensure during operation:

1) The removal or minimum allocation in the air of the working area, the atmosphere and wastewater pollutants, heat and moisture, and the protection of air, open water bodies and soil pollution;

2) The elimination or reduction of noise, vibration, static electricity, ionizing and non-ionizing radiation and other physical factors;

3) Ergonomic requirements for production equipment and workplace organization.

The main directions of the inactivation or reduction of the intensity of production factors in the organization of production processes, the design and modernization of production equipment must be:

- The replacement of hazardous substances harmless, or less harmful;

- Replacement of dry processing methods wet dusting materials;

- The use of hydraulic and pneumatic transport of dusty materials in transit;

- Sealing equipment and facilities;

- A continuous process;

- Automation of technological processes connected with the ability to highlight;

- Automatic block production equipment and sanitary facilities;

- The use of gas analyzers and sensors associated with the automatic protection system (self-blocking, emergency ventilation, etc.);

- Capture, recovery and treatment of process emissions and effluents from the treatment of industrial pollution;

- Reduction of water consumption and water, the widespread use of recycling and reuse of water supply;

- Maximum utilization of solid industrial waste;

- Replacement of processes and process steps associated with the occurrence of noise, vibration and other adverse factors, processes or operations, which provide the elimination or reduction of the intensity of these factors;

- Sound attenuation and vibration cushioning;

- Replacement of electric heating and flame-emotive use of gaseous fuels;

- Thermal insulation of heating, equipment surfaces material wires, ducts, protection of jobs from the convective and radiant heat;

- The protection of jobs from ionizing and non-ionizing radiation;

- Comprehensive mechanization and automation of manufacturing processes and operations using the remote control;

- The rational organization of jobs in accordance with the severity and intensity of labor;

- The location of controls within the zone motor field and ensuring optimal body position of the worker.

In the development of technological processes and designing equipment must be possible maximum mechanization equipment repair and associated assembly and disassembly and observance of safe conditions during repair work. In order to ensure safe operating conditions and production processes, which when applied, refining, processing and production of inorganic, organic and polymeric substances and materials can be released and the explosion and fire hazardous gases, vapors and aerosols in the technological part of the project should be given full characteristics of these properties. In the absence of such data, you must first start to design undertake a comprehensive study of substances and materials, and to establish their degree of danger and harm, and the expected volume of discharge into the working area of gases, vapors and aerosols in the production process and to develop measures to reduce hazards. In the documents accompanying the machinery and equipment (passport, instructions etc.).Should be specified measures to prevent the influence of harmful factors.

The documents must include:

- Wiring diagrams local exhausts, shelter ventilation system with an indication of exhaust air and the required speed, vacuum under different operating conditions;

- The parameters of the generated noise and vibration reduction measures at the installation and repair of equipment;

- How to install and test the effectiveness during installation and during operation guards, automatic lock, alarm, etc;

- Complete the necessary devices (service platform, shelter, lighting, etc.) For normal maintenance and repair of equipment;

- The required tools and accessories for lifting, removal and installation of equipment for installation and repair it.

When you change the production profile of the enterprise, as well as the introduction of new production processes and the use of new raw materials and equipment necessary approvals from authorities state sanitary supervision. The workshop is designed to handle the finishing parts after machining, and welded assemblies and rolling rolls. Items received in the shop, housed in a warehouse in accordance with the required processing technology with heating furnaces, quench baths and ovens for special treatment (carburizing, nitrating, etc.).[5]After processing of the details supplied in clearing office, then in the etching, further technical site control and warehouse. For details of the surface hardening shop has specialized site. Finished parts are checked by technical control service and arrive at the warehouse of finished products. The shop is serviced with overhead cranes and floor with rail trolleys. In thermal hardening shop made metal products to give them increased hardness. The process consists of the following stages: heating of products in an oven at a temperature of 800-900 ° C, rapid cooling baths (water or oil), a secondary heating to 850-350 ° C followed by cooling bath filled with salt solutions or oils. Surface temperature furnaces - 80 ° C. Workers gesture with air / no showers. Job indestructible classified moderate severity (II a).In the measurement of the parameters of the microclimate in the workplace summer found that the air temperature was 28-37 ° C, relative humidity - 45-52%, thermal radiation - 600-2300 W / m2, air velocity - 1-1.5 m / s .When conducting physiological research workers noted: body temperature was 37.8 ° C (37. 0 ° C), the temperature of the skin of the forehead -35.2 ° C (33.8 ° C), pulse - 120 beats / min (82) moisture losses - 8.9 g/min (2.5) (figures in brackets for the control group).[6]

When working conditions surveys blast furnace found that workplace basic trades (hearth and their henchmen, ladle, bottlers and others.) Microclimate parameters varied within the following limits: in the summer (winter) air temperature was 30.8-45,5 ° C (15. 6-36.7 ° C), relative humidity - 45-65 (29-7, air velocity - 0.7-5.2 m/sec (0.8-3.5). The intensity of the infrared radiation at number of transactions - from 350 to 1000 W. fundamental work occupations is heavy (III).Job major professions is heavy (III).When studying the reactivity of workers in this group revealed that the phagocyte activity of blood Europhiles is lower than in the control. In the study of morbidity with temporary disability (100 employees), it was found that the major workers in group I (furnace man et al).It is 188.3 and 1214.2 of the day event, while the workers in Group II (control - locksmiths, electricians) - 88.3 cases u 559.1 days. On average, the production of the incidence is 106.4 cases and 687.6 days. Job shop operators in the continuous casting of steel is tracking devices (motor reactions without significant muscular effort - pressing the buttons off toggle switch, voice response, severity relates to the light (I a).Workplace operators located in specially equipped control stations, completely isolated from the plant. The temperature of the walls, floor, ceiling, is from 29 to 32 ° C. In summer the temperatures in the shop - 27-30 ° C instant casting temperature increases by 2-4 ° C) and relative humidity - 55-60, air velocity - 0.1-0.2 m/s.

When conducting physiological studies it was found that at the end of operation (in parenthesis - basic Band) body temperature was 36,8 ° C (36,7 ° CJ, forehead skin temperature - 34.0 ° C (33.5 ° C) temperature skin brush - 29,3 ° C (28.5 ° C)., heat transfer by convection and radiation - 55 kcal / h (100) moisture loss- 156 g / h (60)When conducting physiological studies it was found that at the end of operation (in parenthesis - basic Band) body temperature was 36.8 ° C (36.7 ° CJ, forehead skin temperature - 34.0 ° C (33,5 ° C) temperature skin brush - 29.3 ° C (28.5 ° C)., heat transfer by convection and radiation - 55 kcal / h (100) moisture loss - 156 g / h (60).Furnace and thermal spans serviced cranes 15/3 or 20/5 tons. In the electric furnace bay set to melt the flux capacity of 1 or 2.5 m and a device for tilting the electrodes before loading it into the molds. Materials handling equipment similar to that office equipment compartment ESR. Thermal equipment offices ESR presented either electric wells or chamber furnaces with roll-out hearth. Given the highly explosive placed in separate rooms plots etching cyanide, liquid nitration furnaces lead - bathing, preparing solid carburizing, diffusion and metallization of booking if they are located outside of the stream:

1) Cooling the heated portions of the parts;

2) Cleaning equipment parts;

3) Machine converters and generators tube high frequency current (except technically based cases);

4) Portions of the collection, sorting, short-term storage of waste thermal treatment storage areas of chemicals.

1.1 The object plan, type of work, type of ventilation

Workshop with large furnaces working with explosive protective gas is provided with a special secure ventilation, and the floor structure performed so as to avoid forming stagnant gas bag, which could accumulate lighter than air gas mixtures, in particular hydrogen or products dissociation of ammonia. Explosion and fire areas separated from other portions of the walls of materials having a fire resistance rating of not less than 0.75 hours. In the explosion and fire facilities are not used asphalt flooring, decking rubber or linoleum. Fire extinguishers are sealed, have account numbers and labels, markings on the body, painted in red color signal, and placed at a height of not more than 1.5 m above floor level. On platforms where there are cooling down the details, you should avoid touching the metal as it cooled to 400 - 500 deg. C, appearance does not differ from the cold metal.[4] thermal radiation air microclimate

Ferroalloys are trained in a special room in the hopper containers delivered on railway platforms into the feedstock span. Storage of electrodes arranged in special rooms, located at the ends of the span, and equipped with racks and lifting devices (figure 4).

Microclimatic conditions are studied directly in the workplace, and in the work area (air sampling, evaluation of the effectiveness of ventilation, etc.).In thermal hardening shop is made of metal parts to impart increased hardness. The process consists of the following stages: heating of products in an oven at a temperature of 800-900 ° C, followed by cooling baths (water or oil) or in the open air in the shop premises. The surface temperatures of 80 ° C oven, work indestructible associated with the transfer of the load up to 10 kg. In the measurement of the parameters of the microclimate in the working sheet is set: air temperature - 28-37 ° C, relative humidity - 45-52%, air velocity - 1-1.5 m /s outside air temperature - 25 ° C. The intensity of the radiation from the furnace during loading and unloading of parts up to 2500 W / m.

Ventilation thermal shops. Hot shops in the industry are all the production facilities where the work process is accompanied by a large release of heat into the air.

Such workshops include foundries and smelting (hearth, converter, and electro steel), thermal, forging and rolling. Ventilation hot shop must solve two problems laterals radiant and convective heat, which is released during the operation of equipment and removal of smoke and harmful impurities (carbon monoxide, sulfur dioxide, ammonia) (figure 5). Since heat and smoke come in huge quantities (the temperature in the shop even winter does not release below + 300 ° C, while in summer and does is + 4500 C) provide reasonable efficiency of ventilation is difficult. In thermally shop used almost all types of ventilation: natural, general exchange supply and exhaust and local. [2]

Figure 5- Hot object thermal plant

Air balance the hot shop determines the rate of compensation air deleted local suction, ventilated ceilings and general exchange exhaust ventilation. To prevent the spread of odors associated with cooking, pressure is maintained in the hot shop lower than in adjacent areas. This is achieved maintenance of ventilation, in which the overflow from adjacent spaces in the hot shop is at least 10% but not more than 60% of the total flow of air to be removed from hot shop (figure 6).

Combustion air supply air ventilation systems should be sited way to prevent recirculation of air removed local suction and ventilated ceilings. Supply and exhaust fans should be installed so that the it was possible to perform periodic inspection and cleaning. Exhaust fans serving the local pumps and ventilated ceilings, removing vapors and or particles of fat, shall be equipped with drainage and tray outflow and collect fat. Such electric fan must be made to performance, taking into account work at high temperatures or at possible, be located outside the flow of the exhaust air. Fire source and easier to remove after the elimination of fire. When triggered fire extinguishing system chemical reagent under high pressure is sprayed over the fire source through nozzles located in the local suction cavity above the cooking equipment. Upon contact with the hot surface of the reagent coated fat, foam is formed absorbing flammable vapors and prevents them from fire.

Figure 6 -Ventilation heat treatment shop

Almost all kinds of hot shop equipment shall be provided with local suction. Calculation of local ventilation, as well as its installation is made in such a way as to ensure maximum removal of contaminants.

1.2 Solution algorithm

1) Characteristics shop for heat dissipation:

- Thermal plant is classified as "flammable" as excess sensible heat above 20 kcal / m3• h.

2) Source selection convective and radiant heat in the thermal workshop:

- Furnace, hot parts.

3) The period of the year at the time of the survey:

- Warm (outside air temperature over 10 ° C).

4) Category of work performed (Appendix A):

- Moderate severity II b.

5) Regulated microclimate parameters (optimal and acceptable):

- In accordance with 2.3. SanN&R 11-13-94 in thermal shop set allowable rates microclimate, as on the technological requirements of production and technical reasons it is not possible to provide the best standards.

6) Execution of the survey results in the form of a protocol .Characterization of thermal exposure of workers:

- The intensity of thermal radiation is 3500 W / mg, which does not comply with p. 2. 9. San N&R 11-13-94 (from open sources of irradiation intensity irradiation does not exceed 25% of the body surface should not exceed 140 Bronx / H2).

7) The surface temperature of ovens (80 ° C) than the allowable (45 ° C) to 35 ° C (Appendix A).

Conclusion: the hygienic evaluation of the meteorological conditions in the thermal workshop, which is classified as "hot" in the warm season, when performing work of moderate severity found that the performance of the microclimate not meet hygienic standards established SanN&R 11-13-94 (2.2 ., 2.9., 2.11): air temperature exceeds maximum of 10 ° C, the high mobility of air, the intensity of thermal radiation above the permissible level (more than 25 times), the surface temperature furnaces is 80 ° C at the rated 45 ° C.Working in such conditions can have adverse effects on the health of workers and cause functional impairment of a number of body systems, promoting the growth of morbidity with temporary disability and the development of occupational diseases. In order to preserve the health and health should be taken to develop a range of recreational activities (list).In accordance with the "Sanitary rules of the organization processes and hygienic requirements to manufacturing equipment " N 11-13-94 sets out the requirements for the production process and equipment of the thermal plant. ).[3]

Solution 1. Determine the required ventilation in the room with the following terms: as a result of leakage through cracks in the air equipment Wednesday workroom volume V = 875 m3 received a pair of gasoline, whose concentration is 15 mg / m3.

G=H•q

G=100•50=5000 l/h

2. CONCLUSION

In my work I tried to open a theme microclimate and learn whether microclimate parameters in thermal plants. Before I started to learn the value of microclimate and their parameters, and that applies to them. For example: One group of premises characterized by significant heat release associated with the nature of the process, which exceeds the amount of heat loss (20 kcal / h, m3), regardless of the ways they come into the room (convection or radiation).This group of buildings called hot shops. Heat is supplied to them from the hot objects and surfaces, and hot molten masses. It is customary to test the performance of new HVAC systems prior to their commissioning. Typically, air data measurements are carried out throughout the room. The results of measurements are used to assess compliance with the parameters of air in rooms with the general requirements of thermal comfort, as well as for the evaluation of local discomfort. However, very often the survey methodology does not meet the standards. In some cases, the survey is limited to only check the general conditions of thermal comfort, while local discomfort generally not investigated or selected the wrong criteria for its evaluation. In other cases can be properly selected measurement locations in the room.

Lack of accuracy can be the cause of differences of perception of the real and expected climate assessment based on the results of measurements. Obviously, held appliances such assessment of the likelihood of drafts to be erroneous. Incorrectness of the survey methodology and analysis of the test results of the surveys also lead to an incorrect evaluation of the microclimate. In many cases, the full-scale survey of limited evaluation of any one of microclimate parameters, such as temperature component. However, the feeling of comfort people can be formed under the influence of air quality, noise and other factors not related to the thermal environment. As shown Fang (1996), the indoor air quality perceived as better at lower temperature and relative humidity, i.e. with a decrease in the enthalpy of the air.

Therefore, we can assume that in areas with polluted air people desirable temperature reduction is not due to thermal comfort, and for the general improvement of the subjective perception of the indoor environment. In such cases, if the preparation of questionnaires and analysis of the results did not take into account these circumstances, it is quite possible erroneous conclusions. Using optimal microclimate parameters, not all buildings can be appropriate and economically justified. Therefore, domestic norms are widely used concept of acceptable parameters, is a reasonable boundary values at which no adverse effects on the human body. Set out in the course work material allows a number of key provisions that are essential for understanding the process of microclimates. This fact determines the extremely dynamic microclimatic conditions, but their common characteristic is largely dependent on the nature of production, processes that occur in them, and can to a certain, sometimes lengthy period of time to remain more or less constant.

On this basis, classify existing production microclimatic conditions. The working environment in terms of hygiene is a set of physical factors (temperature, humidity, air velocity and thermal radiation) affecting thermal condition of the body and its heat exchange with the environment of industrial premises. The formation of climate significantly affect the process and the organization of air in the workplace, as well as the time of year and the climate of the area.

Depending on the character of the technological process the following types of climate:

1) Optimal (comfortable), which is created when you use air-conditioning systems in the electronics industry, precise instrument and others. Industries.

2) In conclusion, I would add that the implementation of all the above listed items indoor climate should be diligent work of production workers and manufacturing. It should better abide microclimate. Study of the thermal plant nor observe all the rules because of this deteriorating health.
