Dredging device for pole plate dripping pipe of wet electrostatic precipitator

Abstract

A dredging device for a pole plate dripping pipe of a wet electrostatic precipitator is composed of the pole plate dripping pipe (1), an outer connector (2), a short pipe (3), a tee joint (6), a pipe plug (7), an inner connector (8), a valve (9), a water receiving tank (10) and a hairbrush (11); the pole plate dripping pipe (1) is connected outside the precipitator through the outer connector (2) and the short pipe (3), the tee joint (6), the pipe plug (7), the inner connector (8), the valve (9) and the water receiving tank (10) are arranged at the end of the short pipe (3), scale on the inner wall and dripping holes of the pole plate dripping pipe is cleared through the hairbrush (11) after the pipe plug (7) is taken down, and sediments in the pole plate dripping pipe (1) are discharged regularly through the valve (9). According to the technical scheme, the inner wall and the dripping holes of the pole plate dripping pipe can be effectively prevented from being blocked, and the wet electrostatic precipitator can be operated stably for a long time by cleaning the pole plate dripping pipe and discharging the scale regularly outside the precipitator.

Description

technical field [0001] The invention relates to a dust cleaning device of a wet electrostatic precipitator, in particular to a device for unclogging a dripping pipe of a pole plate of a wet electrostatic precipitator. technical background [0002] Wet electrostatic precipitator is a kind of purification equipment used to deal with trace dust and fine particles. It is mainly used to remove dust, acid mist, liquid droplets, aerosol, PM2.5 and other harmful substances in wet gas. It has dust removal efficiency. High, small pressure loss, simple operation, low energy consumption, no moving parts, no secondary dust, can work below the flue gas dew point temperature, can be combined with other flue gas treatment equipment, flexible and diverse, etc., is an industrial flue gas One of the ideal equipment for pollution control, it is widely used in acid removal and fog removal in various industrial production processes. The use of the wet electrostatic precipitator is divided into t...
