PROVIDING OZONE-ION AIR INDOOR ENVIRONMENT FOR KEEPING LIVESTOCK AND POULTRY

The paper reports on the studies carried out on the pre-incubation treatment of chicken eggs in the disinfection chamber of a hatchery using an air ozonizer. It has been established that the content of ozone and negative ions in the disinfection chamber depends on the chamber volume, the location of the ozonizer outlet and the saturation time of the disinfection chamber of a hatchery. It is noted that when the saturation of the disinfection chamber of a hatchery with ozone and ions increases, the concentration of ozone reaches up to 12 mg/m3, and ions – 2500 pС/m3. Mathematical models describing the working processes of ozone saturation and decomposition in the hatchery disinfection chamber have been obtained. The main parameters and the required operating modes of ozonizers with a concentration of 0.12 mg/m3 for ozone and 490 pС/m3 for ions have been determined. The concentration of ozone and ions in the disinfection chamber of a hatchery, depending on the operating time of the ozonizer, is represented by a power function. It has been determined that in order to ensure the ozone concentration in the chamber of 5 mg/m3 and negative ions of the order of 500 pС/m3, the ozonizer should operate for 30 minutes. At the same time, specific energy consumption for achieving the required ozone concentration in the disinfection chamber of a hatchery will amount to 2.2 kWh/g, the specific energy consumption for the production of 1000 eggs will amount to 0.0004 kWh.
