Dust collection polar plate of wet-type electric dust collector

Abstract

The invention relates to a dust collection polar plate of a wet-type electric dust collector. The surface of the dust collection polar plate is in a convex-concave shape, a slot is formed on one concave part, the slots are arranged in rows on the surface of the polar plate and uniformly distributed, the centers of the two rows of slots are arranged in a staggered manner, the slots are distributed in a triangular shape, and are smoothly connected with each other, and the three-dimensional shape of each slot is a spherical crown body or a pyramid body. The concave-convex dust collection polar plate has a function of transversely buffering and uniformly distributing the water flow, the flow direction of the water flow can be controlled in a guiding manner, a uniform water membrane can be formed on the entire surface of the polar plate, the rinsing water amount of the polar plate is reduced, and the water consumption can be reduced; the length of the polar plate can be increased from 6m to 8m to 8m to 13m, and the occupied area of the equipment can be reduced; the formation of channeling on the polar plate can be avoided, the running stability of the equipment can be improved, and the purification efficiency can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of wet electrostatic precipitators, and in particular relates to a dust collecting pole plate of a wet electrostatic precipitator. Background technique [0002] With the rapid development of my country's economy, the discharge of various air pollutants has increased sharply, and smog and haze continue to appear in some regions and cities, which has become one of the factors that threaten my country's human health and sustainable social development. The main components of haze weather are various fine particles, including fine dust, sulfate, and nitrate aerosol particles. Therefore, the control of fine particles and aerosol particles is a key issue in controlling haze. [0003] Electrostatic precipitator and bag filter are currently widely used high-efficiency dust removal and purification devices, and the purification efficiency can reach more than 99%, but the removal efficiency of fine particles of 0.1-2.0...

AI Technical Summary

Problems solved by technology

[0008] In order to ensure the stable operation of the wet electrostatic precipitator, the key issue is to form a continuous and uniform water film on the dust collecting plate. When the wet electrostatic precipitator is used in a large scale, it is more hoped that the plate should be manufactured as long as possible. The smaller the area, but when the water film flows down by itself, encountering obstacles or uneven surfaces, the direction of the water flow will change, and a complete and uniform water film cannot be formed
