Protection of environment of livestock facilities on the basis of air electrofiltration

Abstract

Domestic animal husbandry has leveled up manufacturing since the middle of the past century to provide the food security of our country. However, this could not but cause side effects, that cannot be neglected due to an increase in the production capacity of the agroindustrial complex. One of the most important signs of the "industrialization disease” affecting animal husbandry is the excessive ecological stress on the environment near livestock farms, associated with permanent massive ventilation emissions from livestock buildings. These emissions are saturated with dust and aerosol particles, viruses and microorganisms, vaccines, harmful and foul-smelling gases (hydrogen sulphide, ammonia, methane, intestinal gases, etc.), as well as a large amount of thermal energy spent on creating the optimal temperature balance inside the livestock buildings . This "cocktail” certainly has negative impact on the ecosystem near the livestock farms. To solve this problem, it is proposed to use high-performance purification and disinfection systems based on air electrofiltration. A two-stage wet electrostatic precipitator with a high dust holding capacity and a continuous regeneration of collecting electrodes was developed for this reason. Its application allows highly effective purification and disinfection of ventilation emissions from dust and aerosol particles, viruses and microorganisms, vaccines, serums, and harmful and foulsmelling gases. Introduction of this electrostatic precipitator into the purification and disinfection systems and the application of partial recycle system will make it possible to significantly reduce heat losses at livestock farms and increase energy efficiency of the farm.
