Abstract

The aim of this paper is to numerically model the equation for the charging efficiency of aerosol particles in a gas stream. To solve this problem, we obtained a solution to the equation for the efficiency of charging particles with an ion current, depending on the dispersed composition of the particles, the current density, and the distance traveled by these particles in an electric field. As follows from the resulting equation, the number of uncharged particles continuously decreases, which is due to the formation of charged particles, but under the influence of electrostatic forces, the charged particles are constantly deposited on the precipitation electrode. Thus, there are two independent processes that affect the number of charged particles in the active zone of the electrofilter. In this paper, we obtain an equation for the charging efficiency of aerosol particles under real conditions (implemented in an electrofilter), and the results of numerical simulation of this equation, confirming its higher accuracy, compared to the previously used Deitch equation.
