Wet type electrostatic dust collector

Abstract

The invention relates to a wet type electrostatic dust collector which comprises a dust collector body composed of a first dust collector and a second dust collector and a control mechanism. The dust collector body comprises a cavity, a charging device, a washing header pipe, a dust hopper air inlet hopper, an air exhaust hopper and a steam pipe orifice; a dust collecting mechanism, a discharging mechanism and a flushing mechanism are arranged in the cavity; a diffusion plate is arranged in the air inlet hopper; an air inlet mechanism is arranged at an outer opening of the air inlet hopper and comprises a first air inlet pipe, a second air inlet pipe, a first valve, a second valve, a third valve, a fourth valve, a fifth valve, a sixth valve, a first exhaust pipe, a second exhaust pipe, a first ventilation pipe and a second ventilation pipe. An induced draft fan electrically connected with the control mechanism is arranged at an outer opening of the exhaust hopper. According to the wet type electrostatic dust collector, high-dust-content flue gas can be better diffused in the cavity of the dust collector, the dust-containing flue gas is continuously treated, and the dust collection effect after cleaning is improved.

Description

technical field [0001] The invention relates to the technical field of industrial dust removal, in particular to a wet electrostatic precipitator. Background technique [0002] Dust collector, or dedusting equipment, is a device that separates dust from flue gas. It is an important indicator of facilities commonly used in boilers and industrial production, including: the amount of gas processed, the resistance loss of gas circulation, and dust removal efficiency. [0003] According to the processing principle, the dust collector is divided into: [0004] Dry mechanical dust collector, using dust inertia and gravity, is often used in high-concentration dust removal environments such as settling chambers, inert dust collectors, and cyclone dust collectors; [0005] Wet dust collectors rely on the affinity of water to separate and capture dust particles, and are often used as spray towers, scrubbers, impact dust collectors, and venturi tubes; [0006] The granular layer dust...

AI Technical Summary

Problems solved by technology

[0011] 1. Only the distribution plate is installed in the air inlet, and the diffusion effect of the distribution plate is poor;

[0012] 2. Dust removal and dust removal are divided into two independent steps, and they are carried out in sequence. There is an interval for dust removal, and the efficiency is low;

[0013] 3. After the plate is cleaned, the surface is wet, and the effect of vacuuming again is poor
