Abstract

The invention relates to heating and ventilation technology, can be used to humidify the air in poultry houses, and improves the efficiency of air humidification during the cold period and removes dust from it. The system contains air humidifiers 1 installed in the room 2 and connected by a water supply line 3 to a tank 4 divided by a partition 9, a valve 18, a heater 6 with a heat supply line 7 and a valve 12, a pump 8 and after the humidifier a drain are installed in series after the water supply line 3. Pipeline 24. Indoors 2 are also installed sensors 13-14 of temperature and humidity, connected to humidity and temperature regulators 20 and 22, connected by normally open contacts in the supply circuit of valve 12 with control devices 23. Pr and humidity in the room 2 is below the norm by the signal of the humidity sensor 14, the humidity controller 20 is activated, the normally open contacts of which by means of the command devices 23 turn on the humidifiers 1, the valve 18 and the pump 8. The water from the tank 4 flows by gravity through the heater 6 to the pump 8, which supplies water through water supply line 3 to humidifier 1, in which water spraying and air humidification processes take place. The undisturbed water, which is contaminated from air, flows through pipeline 24 to tank 4, where it is cleaned, and passes through partition 9. If the room temperature is humidified below normal when the room 2 is humidified, temperature controller 22 turns on valve 12, which supplies the coolant to the heater 6, heating the water going to the humidifiers 1, and the latter provides a normalized level of temperature.

The invention relates to a ventilation heating technician, e, and can be used to humidify the air in poultry houses, which are inherent in the presence of organic dust.

The purpose of the invention is to increase the efficiency of regulating the humidification of the air during the cold period and its cleaning from dust.

FIG. 1 depicts a water supply control system for air humidifiers with applied main functionalities (mechanical and electrical communication lines between structural elements; FIG. 2 shows the structure of an air humidifier.

The water supply control system of the air humidifiers contains air humidifiers 1 installed in the room 2 and connected to the water supply line 3 through the tank 4 with the level 5 regulator.

The partition 9 consists of successive layers of the mesh filter 15, hygroscopic material 16 and a coarse mesh support frame 17. Humidifiers 1 are installed in room 2 above the bird location zone and connected by electric power lines to the power supply of FIG. 1).

In front of the heater 6 on the water supply line 3 after tank 4 there is an additional control valve 18,

In the electrical supply circuit of the valve 12, normally open contacts 19 and 21 of the humidity controller 20 (B) and peryrj temperature sensor (PT) respectively are connected in series.

Manual switching on and off of humidifiers 1, valves I2 and 18, and pump 8 is performed using control devices 23, for example, x: magnetic starters, while for automatic control mode, an open contact of humidity controller 20 is turned on in the circuit of each control device 23. Drain water from uvg. of the climber 1 to the tank 4 is produced by gravity through the pipeline 24,

The fitting 25 (FIG. 2), located under the partition 26 in the pallet 27 of the humidifier 1, is connected to the water supply line 3, and the fitting 28, located above the partition 26, is connected to the pipeline 24, In the partition 26 there is a hole blocked

stopper 29. When necessary, water is drained from pipe 24 by means of taps 30,

The humidifier water supply control system operates as follows.

When the humidity of the air in room 2 is lower than normal, the humidity sensor 14 (FIG. 1) triggers the humidity controller 20, the normally open contacts of which include the humidifiers 1, the valve 18 and the pump 8 by means of the commander 23, and prepare contact 19 (PB) to turning on valve 12 i.e. contact 19 (PB) is closed. The water from the tank 4 flows by gravity through the heater 6 to the pump 8, which supplies water through line 3 of the water supply to the sump 27 of the humidifier 1, in which the process of spraying water and air humidification takes place. At the same time, the undisturbed air sprayed water, taken up in pollution from the air, flows through the partition 26 to the fitting 28 and flows through the pipeline 24 into the tank 4, where, seeping through the permeable partition 9, clearing suspended particles of dust, and mixed with fresh tap water enters the water supply line 3 of the humidifiers 1. In this case, the upper layer of the strainer I5 in the partition 9 provides mechanical purification of water from the dissolved dust, which is retained on the surface of the strainer 15, which provides the reliability of its periodic cleaning and removal of deposits (for example, by dismantling the filter). The middle layer of the partition 9, having a hygroscopicity and porosity, provides suction of water from the upper layer and its passage into the lower cavity 10 of the tank 4. The lower layer of the partition 9 in the form of a coarse mesh network 17, is a support for the upper layers of the partition 9, at the same time time does not prevent water from flowing down. In order to disinfect the accumulating soil layer, germicidal lamps (not shown) may be installed above it on the partition wall 9, which may be switched on periodically. The use of tank 4 with a partition 9 provides drainage and cleaning of undisturbed water in the humidifier I, good 10

the gift of which dust from purified air is cleared, the sag guitars of the hygiene condition improve in the next 2, improve. At the same time, reuse (spraying in humidifier 1) undigested water is provided.

If necessary, for example in the summer period, contaminated water, drained from humidifiers 1, can be removed into the sewage system by means of taps 30, thus providing deeper cooling of the humidified air in order to reduce heat losses in the room.

The interposition of the tank 4 and the heater 6 can be used to reduce the hydraulic losses in the heater 6, i.e. the location of the preheater 6 under the tank 4 provides water by gravity from the tank 4 through the heater 6 under the influence of the differential levels of the location of the tank 4 and the heater 6,

Moist air from humidifier G is supplied to room 2, providing a significant area of moisture in the room. I

Further, the humidification system can function as follows. If the humidification of the air in room 2 causes a shortage of heat in room 2 (i.e., the temperature in the working area of the room decreases below normal), the temperature regulator 22 triggers according to a signal from temperature sensor 3 (tj in FIG.) and with its normally open contact 21 (PT) it turns on valve 12 (since contact J9 (RB) is already closed). The inclusion of the valve 12 may be in a different sequence. Namely, during the heating period (i.e., during the period when the heating system of the room 2 functions by the command of the temperature controller 22) contacts 21 (PT) in the circuit of valve 12 are permanently closed, and contacts 19 (PB) are closed and valve 12 it is activated by the command of the humidity controller 20 (i.e., as needed, in humidifying the air in room 2).

After turning on the valve 12, the coolant enters the preheater 6, heating the water supplied to the humidification, which ensures the heating of the humidified air. Heated humidified air, entering room 2 after humidifier I, excludes dis30 zones.

comfort in the room and provides the same temperature of humidified air as the normalized temperature level i.e. installed on the jiHTOpe 22 regulator indoors. Drain from humidifier 1 undiluted water and its cleaning in tank 4 occurs in the

: e sequences, as described in the operation of the humidification system without heating the water.

In this way, during the heating period, the humidification system is regulated. In case of insufficient

Thermal power of heater 6, pins 19 (PB) and 21 (PT) can be multiplied to include additional thermal power of the room.

Also, the use of proportional control in the circuit of the temperature controller 22 - valve 12 allows the amount of heat transfer medium entering the preheater 6 to vary in proportion to the deviation of the air temperature in the working area of room 2, which allows a more flexible functional relationship between the humidification and heating systems. .

The use of the system ensures the elimination of discomfort zones in the humidification zone and the disturbance of the heat supply pool, room balance 2, by adjusting the humidification system during the heating period due to the functionally connected heating of the water supplied to the humidification. At the same time in the summer (unheated) system
