Efficient tubular plate vertical current wet-type electrostatic dust collector

Abstract

The invention discloses an efficient tubular plate vertical current wet-type electrostatic dust collector. The efficient tubular plate vertical current wet-type electrostatic dust collector comprises a shell (1), wherein an anode dust collecting mechanism (2) arranged vertically is arranged in the shell (1) and adopts a tubular plate structure formed by dust collecting boards; a vertically arranged cathode wire (31) with discharge points is arranged between the tubular plates of the anode dust collecting mechanism (2); the upper end of the cathode wire (31) is fixed on a cathode girder (32) above the cathode wire (31); the lower end of the cathode wire (31) is fixed on a tension frame (33) blow the cathode wire (31); the cathode girder (32) is connected with a high voltage power supply system (4) through conductive wires; a cathode system is formed by the cathode girder (32), the cathode wire (31) and the tension frame (33). As an electrostatic field formed by the tubular plate anode dust collecting mechanism and the cathode wires, effectively solves the problem of difficult removing of PM2.5 tiny particles, acid mist, liquid drops, aerosol, heavy metals and the like from the smoke, and the efficient tubular plate vertical current wet-type electrostatic dust collector is widely used.

Description

technical field [0001] The invention relates to a wet electrostatic precipitator applied in the field of environmental protection technology, specifically a device capable of effectively removing PM2.5 fine particles, acid mist, liquid droplets, aerosols, organic odors, heavy metals, etc. Plate tube vertical flow wet high-efficiency electrostatic precipitator for harmful impurities.
