Theoretical substantiation of resource-saving system of recycle air clearing

Abstract

Cleaning and disinfection of recirculated air of livestock buildings are a critical factor in the formation of an optimal climate for agribusiness. The modern system of cleaning of the ventilation air does not allow one to analyze the composition of the air environment in the entire spectrum of harmful current components, which are calculated at the maximum values generating a hazard in the air of livestock premises without taking into account the physiological characteristics of animals, which leads to an increased energy process of cleaning and disinfection of the ventilation air. The developed and patented system of the automated regulation of the microclimate parameters allows real-time analysis of the current status of air environment quality of the working area livestock facilities and, if necessary, adjusting the operating parameters of the system clear key and disinfection of recirculation of ventilating air to maintain the main parameters of the air environment, such as concentrations of dust, microorganisms, and harmful gases (ammonia and hydrogen sulfide), lower values of maximum permissible concentrations. Mathematical modeling of the changes process in the concentration of harmful current components in the air helped to create a model of concentration dependence of such operating parameters of the system as the efficiency of cleaning and decontamination and the ventilation rate. The process design maintaining the air quality at the required level by the example of the pigsty showed that the vent, cleaning circulating air from dust with the required efficiency, allows one to achieve the required degree of purification of the air environment from ammonia and hydrogen sulfide. The application of the proposed system of the automated control of the microclimate parameters in livestock building will maintain the required parameters of air environment quality in combination with a reduction of energy consumption to maintain an optimal climate.
