Abstract:
The purpose of this paper is to analyse of the behaviour of gas with dust particles dynamic flow in industrial plate–type electrostatic precipitator (ESP). An ESP is a device that removes pollutants from the air by an electrical charging process of the dust particles. A high-voltage discharge wires create Corona discharge and serve as ions source for dust particles charging. The dust particles migrate to collecting plates. The electric wind by ions causes, together with primary flow of the gas, a secondary turbulent flow that affects the overall collection efficiency of the ESP. The turbulence plays an important role in particles motion. The secondary flow and induced turbulence is not entirely understood in electrostatic precipitator phenomena. From this reason the turbulence is study by simulating and measuring methods. Also, the turbulence flow of the gases has influence on the fine dust particles, pushing particles away from the collecting plates after the dust particles were collected on the surface electrodes.
