A permeable wire mesh dust collector and its wet electrostatic precipitator

Abstract

The invention discloses a penetration-type wire mesh dust-collection pole. The penetration-type wire mesh dust-collection pole comprises dust-collection anode plates, a dust-collection framework and a water distribution device. The dust-collection anode plates are fixed to the dust-collection framework. The dust-collection anode plates are wire mesh plates and are fixed to the outer side of at least plane of the dust-collection framework. Metal plates are arranged on other sides of the dust-collection framework. The dust-collection anode plates and the metal plates are connected and surround the dust-collection framework to form a tank. The water distribution device is arranged in the tank and is used for feeding water into the tank. The invention also discloses a wet-type electric deduster with the wire mesh plates. The wire mesh plates are used as the dust-collection anode plates so that the problem that an electrode plate of the existing wet-type electric deduster forms all-area uniform water film difficultly and local dry spots and severe local back corona are formed is solved; dust accumulated on an electrode plate is fully and ideally removed; equipment is simple; and reconstruction and construction costs are low.

Description

technical field [0001] The invention relates to the field of flue gas purification for environmental protection, and more specifically relates to a permeable wire mesh dust collecting pole and a wet electrostatic precipitator thereof. Background technique [0002] At present, the wet electrostatic precipitator uses water spray to form a water film on the surface of the dust collector, and the cleaning water flows downward under the action of gravity, washing away the dust deposited on the electrode plate, and then falls into the dust collector through the sewage pipe. The ash hopper below the dust collector is discharged. Compared with the dry electrostatic precipitator, the wet electrostatic precipitator has the following advantages: no vibration equipment is required, and secondary dust is avoided; since there is always a layer of water film on the electrode plate, the dust is collected on the electrode plate and immediately absorbed by the water. Membrane flushing preven...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the technical problem that the dust collection plate of the existing wet electrostatic precipitator cannot form a uniform water film on the dust removal plate, and it is easy to generate dead spots for dust removal, thereby making the dust removal efficiency of the wet electrostatic precipitator low
