The recirculation system has an additional recirculation fan 10, the supply of which is chosen in order to increase the speed. The air inside the recirculation duct 6 did not change the air velocity inside the incubator chamber.

The recirculation fan 10 is interlocked with the electrostatic precipitator 11 and installed after the intake valve 12 of the supply air. The climate control system contains a control sensor unit 5, which by its outputs is connected respectively to the inputs of the heater control unit 13, the humidifier 14, the recirculation fan supply control unit 15, the electrostatic filter 16, the ozonizer 17, the outputs of which are. in turn, are connected to the appropriate executive bodies, namely the heater 18, the humidifier

19, a recirculation fan 10, an electrostatic precipitator 11, and an ozonizer 20.

The incubator works as follows.

Through the inlet valve 12 and with the help of the injection fan 4, the air is withdrawn from the atmosphere and the passage through the electrostatic precipitator 11 is cleaned of dust and microorganisms and saturated with negative aeroions. Next, the air enters the heater 18, humidifier 19, ozonizer

20, in which, respectively, it is heated, humidified, ozonized, and supplied to chamber 1. Then the air under pressure from the blower fan 4 passes with a minimum

speed (about 0.6 m / s) through the trays 2 with the incubated egg, is taken in by the air inlet 7 to the recirculation duct 6, while part of the exhaust air is discharged through the exhaust valve 3.

During the chick pulling process, dust emission increases, the ion concentration and ozone concentration change (due to the intensification of the chickens respiratory process). An increase in the amount of dust above the maximum permissible concentration (MPC 1 mg / m) affects the control sensor unit 5 and the dust control sensor, which sends a signal to the input of the control unit 15 for supplying the recirculation fan 10. Accordingly, the supply of the recirculation fan increases. until the dust concentration drops below-MAC. With a change in the air exchange rate, the amount of air j passing through the electrostatic precipitator 11 and the ozonizer 20 changes. This leads to an additional change in the concentration of air ions and ozone. The change of the specified parameters affects in the block 5 sensors of control the sensor of concentration of ions and ozone, which give a signal to control the operating parameters of the electrostatic precipitator and the ozonizer in order to compensate for the change in the life-promoting parameters of the microclimate in the incubator.

The output signal of the control unit by the electrostatic precipitator 16 affects the operating parameters of the electrostatic precipitator 11 (electric field strength, corona current density, volume charge density), on which the concentration of azioions depends. The operating parameters of the electrostatic precipitator can be controlled by adjusting the voltage applied to the electrostatic precipitator electrodes, changing the design and geometry of the corona electrode (diameter of the wire corona electrode, number of projections of the needle corona electrode, etc.), changing the electrode spacing.

From the point of view of the electrostatic precipitator automation, it is most effective to control the mode of the electrostatic parameter by varying the voltage applied to the electrostatic precipitator electrodes.

The change in the concentration of ozone in the incubator affects the sensor monitoring the concentration of ozone in 5 control sensors, which sends a control signal to the operating parameter of the ozonizer 20.

In discharge ozonizers, the ozone concentration depends on such operating parameters of the ozonizer as voltage,

O applied to the electrodes of the ozonizer, the frequency and shape of the applied voltage curve, the geometry of the electrodes and the interelectrode gap. Most effective in terms of range

5 control of ozone concentration control of the frequency of voltage pulses applied to the ozonizer electrodes.

Thus, it is possible to influence the operation mode of the electrostatic precipitator and the ozonizer by adjusting various parameters.

However, it is recommended to adjust the operation mode of the electrostatic precipitator and ozonizer by adjusting the voltage of the electrostatic precipitator and the frequency of the voltage pulses of the discharge ozonizer, respectively. In the incubator, optimum concentration of aero ions and ozone in the incubator is maintained by adjusting any mode parameter. The stability of the vitalizing and disinfecting effects is of greater importance both in the period of embryo formation (when eggs are in incubation cabinets) and in the first minutes of chick hatching (during the stay of biological

0 object in hatchers).

Sensors for monitoring the concentration of ions and ozone in the block of 5 sensors for control work continuously and simultaneously. In this case, the electrostatic precipitator 11

5 and the ozonizer 20 can operate in intermittent and continuous operation modes.

For example, when using a two-position control system

0, the electrostatic precipitator 11 and the ozonizer 20 are turned off when the upper concentration value of the aeroions and ozone, respectively, is exceeded, and is turned on when the indicated parameters are lowered below

Level 5, i.e. the filter and the ozone generator in this case work in the intermittent mode.

In case of increased requirements for maintaining the specified values of the concentration of ions and ozone, for example, in the first minutes of chicks hatching, a re-removal system can be used. At the same time, the filter and the ozonizer are in continuous operation (continuous mode), and the established mode of operation of the electrostatic precipitator corresponds to the specified values of ion and ozone concentrations. When the concentration of aeroions and ozone is turned off during operation of the outlet incubator, the aero ions and ozone concentration sensors The control sensor unit 5 is provided with control signals for the operation of the electrostatic precipitator 11 and the ozonizer 20 in order to compensate for the deviations that have occurred.

With a two-position microclimate control system as a whole, for an incubator, not all five, but only a part of the microclimate maintenance devices (humidifier, heater, fan, electrostatic precipitator and ozonizer) may be in operation. In the particular case, when the periods of pauses of all devices coincide, all devices for maintaining the microclimate will be disabled.

When using a two-position system, it is regulated: the energy intensity of the process of maintaining a microclimate does not decrease, since not all devices operate simultaneously and the implementation of the regulation system is forgiven. When using the second deviation control system, all five devices operate simultaneously. When using more complex control units (for example, using special information processing systems coming from the sensors and generating control signals, i.e., flexible change of the incubator program in accordance with the actual situation), the order of the microclimate maintenance devices can be strictly defined in accordance with the selected program.

It is important to note that all microclimate maintenance devices in the incubator work independently of each other. But all five devices interrelate with each other through the air, the various parameters of which they control, and the air affects the biological object (the formation of the embion).

At the same time, a change in one parameter of the air environment, for example, air dustiness, leads to the regulation of the air exchange rate, and a change in the air exchange rate causes a change in the concentration of air ions and ozone.

When the concentration of air ions changes, the humidity of the air changes (as the concentration of ions increases

air humidity decreases, which in turn reflects on air temperature. With such a close relationship between the controlled parameters, maintaining a given concentration of aero ions and ozone is an important factor contributing to the improvement of sanitary and hygienic conditions in the incubator. This incubator allows for a clearer fulfillment of all technological requirements, which results in a decrease in the output of non-conforming products.

In addition, favorable conditions are created for the automation of incubators located in a single production line using microprocessor technology.
