A wet porous roller shutter electrostatic precipitator

Abstract

The invention relates to a wet porous roller shutter electrostatic precipitator. The technical solution is: the dry electrostatic precipitator is equipped with 1~2 wet porous roller shutter dust collectors, the wet porous roller shutter dust collector is located on the side of the air outlet box (7), and the baffle (5) is located on the wet porous roller shutter. The intake side of the dust collector. The bottom of the dust collector body (2) is provided with a water tank (9), the water tank (9) is located between the air outlet box (7) and the ash hopper (11), and the notch of the water tank (9) is flush with the bottom of the dust collector body (2); Drive drum (10) is housed in the water tank (9), and driven drum (6) is housed directly above the drive drum (10), and drive drum (10) and driven drum (6) pass around drive drum (10) and The wet porous roller blinds (8) between the driven rollers (6) are connected. The front side baffle, the top baffle and the rear side baffle of the baffle are successively fixed on the inner wall of the body front side plate, the inner wall of the body top plate and the inner wall of the body rear side plate. The device has the characteristics of simple structure, low cost, reliable operation and high dust removal efficiency.

Description

technical field [0001] The invention belongs to the technical field of electrostatic precipitators. Specifically, it is a wet-type porous roller shutter electrostatic precipitator. Background technique [0002] At present, various types of dust removal devices are mainly used to separate and capture dust from dust-laden flue gas, among which electrostatic precipitators are widely used. [0003] The dry electrostatic precipitator uses corona wire discharge to charge the dust in the flue gas, and the charged dust moves to the dust collecting plate under the action of the electric field force and is collected, so as to separate the dust from the flue gas. Purpose, the cleaning method generally adopts mechanical rapping. Although it has the advantages of large amount of flue gas, low resistance, and high dust removal efficiency, it also has some shortcomings, mainly because of its low capture efficiency of fine particles, and In the process of rapping and cleaning, it is easy ...

AI Technical Summary

Problems solved by technology

[0004] The wet electrostatic precipitator generally adopts the method of water spray overflow to form a layer of water film on the surface of the dust collecting plate, so that the dust and water deposited on the dust collecting plate are discharged through the ash hopper; the wet electrostatic precipitator Although it can effectively solve the problem of secondary dust, it still needs further improvement due to its complex structure, high cost, serious corrosion of internal parts, and low capture efficiency of fine particles.
