收尘原理 Dust Collection Principle

湿式电除尘和干式电除尘的收尘原理相同,都是靠高压电晕放电使得粉尘荷电,荷电后的粉尘在电场力的作用下到达集尘管。湿式电除尘器主要处理含水较高乃至饱和的湿气体,对集尘管上捕集到的粉尘清除方式采用定期冲洗的方式,使粉尘随着冲刷液的流动而清除。

The dust collection principle of wet electrostatic precipitators and dry electrostatic precipitators is the same. Both rely on high-voltage corona discharge to charge the dust particles，and the charged dust particles reach the dust collection tube under the action of the electric field force.Wet electrostatic precipitators mainly handle gas with high to even saturated moisture content,and the method for removing dust collected on the dust collection tube is periodic washing, allowing the dust to be removed with the flow of the washing liquid.
