Coordination of energy parameters of the ultraviolet bactericidal recirculator of air of livestock premises

Abstract

Annotation Purpose. Coordination of energy parameters of the ultraviolet bactericidal recirculator of air of animal premises for achievement of the set value of bactericidal efficiency. Methods. Methods of analysis, mathematical modeling and engineering methods of calculation of ultraviolet bactericidal installations are used. Results. Methods of application of ultraviolet bactericidal (UVB) installations for cleaning and disinfection of indoor air are analyzed. Substantiated design, UVB air recirculator. The dependences of the bactericidal power of UVB radiation sources in the recirculator on air productivity and bactericidal efficiency are determined. The specific power of UVB radiation to achieve the specified value of bactericidal efficiency and rational values of bactericidal efficiency of recirculates for industrial enterprises and general purpose premises are established. Conclusions 1. The specific power of UVB radiation to achieve the specified value of bactericidal efficiency in the range of 80…99.9% with the use of UVB air recirculators. To ensure bactericidal efficiency of 80%, the specific power of bactericidal radiation is 6.5 W/100 m3, and for 99.9% 4.3 times more than – 27.9 W/100 m3. 2. Due to the need to significantly increase the installed capacity of irradiators, ultraviolet air recirculators with bactericidal efficiency of more than 95% should be used in premises of categories 1 and 2, as well as in agricultural production facilities for feasibility study. 3. To achieve a recirculator RPB 1.0 with air productivity = 1000 m3/h bactericidal efficiency = 90% required bactericidal radiation power = 93 W, and for = 99% – = 186 W. Keywords: ultraviolet bactericidal recirculator, air purification and disinfection, bactericidal power of ultraviolet irradiators, bactericidal efficiency of recirculator.
