Electric bag combined dust catcher

Abstract

The invention discloses an electric bag combined dust catcher, which comprises an electrostatic dust collecting unit and a cloth bag dust collecting unit which are connected into a whole, and also comprises a flue gas conditioning system which consists of a shell, a water mist spray device, a flow equalizing device and a drainage channel; the rear end of the shell is arranged at the front end of the electrostatic dust collecting unit and the shell is communicated with the electrostatic dust collecting unit; the front end of the shell is provided with an air inlet; the electrostatic dust collecting unit consists of two groups of flow equalizing plates and a group of flow plug; the two groups of the flow equalizing plates have a perforated plate structure; the flow plug consists of a frame and a plurality of flow baffle plates; the two groups of the flow equalizing plates are orderly arranged in the internal rear part of the shell; the flow plug is arranged in the shell and positioned between the two groups of flow equalizing plates; the water mist spray device consists of a water inlet pipe frame, a nozzle and a drainage channel; the part of a longitudinal water inlet pipe of the water inlet pipe frame, which is provided with a nozzle, is positioned in the shell and the front end part of the shell; a transverse water inlet pipe of the water inlet pipe frame is positioned outside the shell; and the drainage channel is positioned under the rear end of the shell. The electric bag combined dust catcher has high dust collection efficiency and prolongs the service life of a cloth bag.

Description

technical field [0001] The invention relates to an electric bag composite dust collector, which includes an electrostatic dust removal unit and a cloth bag dust removal unit. Background technique [0002] At present, the electric bag composite dust collector is widely used in electric power, building materials, steel, chemical industry, papermaking, food and other industries. The electric bag composite dust collector includes an electrostatic dust removal unit and a bag dust removal unit, and these two units are connected as a whole. When the electric bag compound dust collector is working, the dust-laden flue gas enters directly from the inlet of the electrostatic precipitator unit first, and the dust particles, after being charged, tend to the dust collection electrode under the action of the electric field force and are collected by the dust collection electrode. , The flue gas after electrostatic dust removal enters the bag dust removal unit, and the clean gas filtered ...

AI Technical Summary

Problems solved by technology

Because the flue gas directly entering the electrostatic precipitator unit not only has high concentration and temperature, but also has a large specific resistance of the dust, which not only affects the dust removal efficiency, but also shortens the service life of the bag of the bag filter unit.
