Abstract
The air environment of livestock buildings requires disinfection and improvement of the gas composition. The most effective method is ozonation. In order to improve the air inside livestock buildings, the authors have developed an electric ozonizer-emitter. Its emitter module consists of two ceramic bases with different-potential tungsten electrodes, one base having an electrode in the form of a honeycomb cell, and the other – in the form of a rod. The ozone productivity is regulated by changing the discharge gap between the emitter electrodes and the conducting plane. It has been theoretically established that ozone formation in a corona discharge depends on the electric field strength between the different-potential electrodes and their heating temperature. In this case, the maximum strength is achieved with a discharge gap from 25 to 35 mm and electrodes with a radius of no more than 2 mm. The effect of electrode heating temperature on ozone formation was studied on the developed design of the ozonizer-emitter in a laboratory of 180 m3 at an air temperature of 25°C above zero. The air gap between the electrodes was 30 mm, the voltage on the emitter varied from 10 to 30 kV, the duration of the ozonizer-emitter operation ranged between 0 and 80 min, the airflow rate induced by the electric fan was 0.3 m/s. It was experimentally established that stable operation of the ozonizer-emitter is observed when the electrode temperature does not exceed 30°C. In the future, the authors plan to introduce the ozonizer-air emitter into the ventilation and air conditioning system of agricultural buildings.
