Results of research on development of electric air ozonizer for livestock rooms

Abstract

The greatest danger from the point of view of infection of farm animals is the air inside the production premises. One of the ways to improve performance and improve the air environment is ozonation. The article proposes the design of an autonomous module of an electric ozonator operating on the basis of a corona discharge, designed to improve the air environment and prevent the spread of contagious animal diseases. A distinctive novelty of the proposed design is the emitter module, made in the form of two ceramic bases with tungsten electrodes fixed on them, on one base in the form of a grid having a honeycomb cell shape, on the other in the form of a needle. Structurally, the emitter provides for adjusting the distance of the discharge gap between the electrodes of the emitter, which ensures the adjustment of ozone performance and increases the reliability of the ozonator as a whole. The results of experimental studies on the ozonation of the volume of the room using an autonomous module of the electric ozonizer operating on the principle of a corona discharge are presented. It has been established that the concentration of the ozone-air mixture increases with an increase in the operating voltage at the emitter electrodes and a decrease in the distance between them. The maximum performance indicators of the installation for ozone (10 mg/m3) were obtained at an operating voltage of 30 kV at the emitter and a discharge gap of 25 mm. An experiment on the effect of ozone concentration in the air on pathogenic microflora showed the effectiveness of the application to reduce pathogenic microflora in the air.
