Wet static cyclone dust collector

Abstract

The invention relates to a wet static cyclone dust collector. The dust collector comprises a conical shell, an air inlet pipe, a water supply part, a discharge electrode pipe, a drain pipe connected with the shell and an exhaust pipe connected with the shell, wherein the interior of the conical shell is hollow and provided with a cavity, and the shell is made of a conductive material; the air inlet pipe is connected with the shell and extends along the tangential direction of the shell; the water supply part is arranged inside the air inlet pipe or inside the shell; and the discharge electrode pipe is accommodated in the cavity of the shell and provided with an axle tube part, a plurality of through holes and a plurality of extension parts, each through hole passes through the inside and outside of the axle tube part, and each extension part is arranged on the outer wall of the axle tube part. Therefore, an electric field can be formed between the shell and the discharge electrode pipe, when waste gas to be treated passes through the air inlet pipe and enters the inner cavity of the shell, particles in the waste gas are electrified by virtue of a corona discharge mechanism of the discharge electrode pipe and move toward the inner wall surface of the shell under the action of the electric field and centrifugal force, at the moment, washing water sprayed from the water supply part flows along the inner wall surface of the shell in a helical shape, thus the particles are washed and removed.

Description

technical field [0001] The present invention relates to air pollution prevention and control equipment, in particular to a cyclone dust collector which additionally adds a corona discharge mechanism to remove dust and uses washing water to clean the inner wall of the chamber. Background technique [0002] The known cyclone dust collector is generally inverted cone-shaped, and the interior is hollow and has a chamber, an air inlet and an exhaust port. When a waste gas to be treated enters the chamber through the air inlet, the The exhaust gas will flow in a spiral shape in the chamber, and the particles in the exhaust gas can move towards the pipe wall under the action of centrifugal force, and then be collected at the bottom of the chamber under the action of gravity, and the purified air can pass through the exhaust exhausted to the outside world. [0003] The general cyclone dust collector is mainly used to remove particles with a larger particle size. As for the sub-part...

AI Technical Summary

Problems solved by technology

[0003] The general cyclone dust collector is mainly used to remove particles with a larger particle size. As for the sub-particle or even nanometer-sized particles, the cyclone dust collector cannot remove them, which makes the cyclone dust collector subject to considerable restrictions in application. limit
