Development of ultraviolet bactericidal recirculator for air purification of livestock buildings

Purpose. Improving the efficiency of the air purification process through the use of the created design and determining the rational parameters of the luminescent ultraviolet bactericidal air recirculator for livestock buildings. Methods. Methods of analysis, mathematical modeling and engineering methods for calculating irradiation installations are used. Results. The methods of application of ultraviolet bactericidal (UVB) plants for purification and disinfection of the air environment in agricultural premises are analyzed. Impact mechanism established of UVB radiation and ozone for pathogenic microflora and harmful impurities in the air of livestock premises is substantiated. The grounded design, the method of engineering calculation and the technical parameters of the UVB air recirculator are determined. Experimental samples of UVB recirculators of air in livestock buildings were made and the results of their production tests are presented. Conclusions. UVB recycle converter with application of luminescent UVB lamps with installed capacity = 180 W and air capacity = 1800 m3/h provides bactericidal efficiency = 75%, and with = 1000 m3/h – bactericidal efficiency = 90%.
