Embodiment Construction

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] see Figure 1-5 Shown: the wet dust and mist removal device, including the electrostatic precipitator 1, and the mist eliminator 2 is fixedly installed in the outlet horn of the electrostatic precipitator 1. In this embodiment, the demister 2 is installed in the outlet horn through a flange, and those skilled in the art can also install it by means of welding or the like. Wherein the dust collector 1 and the mist eliminator 2 are the prior art, the technical problem to be solved by the present invention is how to organically comb...

Abstract

The invention relates to the technical field of electric dust removers, in particular to a wet dedusting and demisting device. The wet dedusting and demisting device comprises an electric dust remover, wherein a demister is fixedly mounted in an outlet horn of the electric dust remover; a polar matching form of the electric dust remover is that a plurality of anode plates and a plurality of cathode wires are arranged at intervals; a plurality of grooves are densely formed in the anode plates, and the cathode wires are arranged in corresponding positions of the grooves; a plurality of needling wires used for discharge at sharp points are densely arranged on the cathode wires; the arrangement direction of the grooves is parallel to an air inlet direction. According to the wet dedusting and demisting device, the grooves are densely formed in the anode plates, and the needling wires are densely arranged on the cathode wires, so that the flue gas speed of the electric dust remover can reach 3.3-3.8 m / s, the airflow distribution uniformity is good, a stable spray water film can be formed at the flue gas speed of 3.3-3.8 m / s, and dust can be effectively removed.

Description

technical field [0001] The invention relates to the technical field of electrostatic precipitators, in particular to a wet dust and mist removal device. Background technique [0002] Wet electrostatic precipitator is a high-voltage electrostatic precipitator used to treat wet gas. It is mainly used to remove dust, acid mist, water droplets, aerosol, odor, PM2.5 and other harmful substances in wet gas. Ideal equipment for atmospheric dust pollution. The wet electrostatic precipitator is usually referred to as WESP. The basic principle of dust removal is the same as that of the dry electrostatic precipitator. It has to go through three stages of charging, collecting and cleaning. [0003] The mist eliminator system consists of the mist eliminator body and the flushing system. The demister is mainly composed of wire mesh, wire mesh grid, wire mesh block and supporting device for fixing the wire mesh block. The wire mesh is a gas-liquid filter of various materials, and the gas...
