Electrostatic precipitators are used in industrial enterprises for waste gas collection. Their implementation prevents air pollution. Electrostatic precipitators charge the gas particles and make them gather on the collection plates. The electrostatic precipitator in the poultry houses can hold 90−95 % of dust and 80−85 % of microorganisms. The electrostatic precipitator use in agriculture is limited due to their costs. For example, a 6 percents increase in the extent of purification increases their relative cost by almost 3 times. To reduce the cost, the charging region number should be reduced to no more than two, and more precise determination of electrostatic precipitator parameters should be made. The article presents the calculations used to determine the critical electric field, initial voltage, specific current, and ion specific number for a two-stage electrostatic precipitator. The calculation was made with mathematical model methods in a software product developed by the authors and intended for the electrostatic precipitator parameter determination. As a result of the theoretical calculations, it was established that with the increase in specific current the ion specific number increases; an increase in the ion specific number resulted in an increase in the extent of purification of the electrostatic precipitator. The parameters of the volt-ampere characteristics were also determined, at which the extent of purification of the poultry farm premises was in the range of 95−99 %.
