Wet electrostatic dust collector pole plate

Abstract

A pole plate of a wet electrostatic dust collector structurally comprises a top water delivery pipe (1), a middle water delivery pipe (2), a uniformly distributed cover plate (3) and a dust collectionpole plate (4). The bottom of the top water pipe (1) is connected with the dust collection polar plate (4) into a whole, the two side faces of the dust collection polar plate (4) and the outer circumferential face of the top water pipe (1) are connected with the evenly-distributed cover plates (3), and cleaning water is sprayed to the inner surfaces of the evenly-distributed cover plates (3) through small holes in the two sides of the bottom of the top water pipe (1); and the water sprayed to the inner surface of the uniformly distributed cover plate (3) under the action of gravity is preliminarily uniform and then falls onto the outer surface of the dust collection polar plate (4) to form a uniform water film. The dust collecting polar plate (4) exceeds a certain height, the middle waterconveying pipe (2) is arranged in the middle of the dust collecting polar plate (4), water films continuously and evenly flow on the two surfaces of the dust collecting polar plate (4), the continuous and even water films are formed on the surface of the dust collecting polar plate (4), and pollutants attached to the surface are removed.

Description

technical field [0001] The invention relates to a key internal part of a flue gas purification device in the field of environmental protection, in particular to a pole plate of a wet electrostatic precipitator. [0002] technical background [0003] Wet electrostatic precipitator is a kind of purification equipment used to deal with trace dust and fine particles. It is mainly used to remove dust, acid mist, liquid droplets, aerosol, PM2.5 and other harmful substances in wet gas. It has dust removal efficiency. High, small pressure loss, simple operation, low energy consumption, no moving parts, no secondary dust, can work below the flue gas dew point temperature, can be combined with other flue gas treatment equipment, flexible and diverse, etc., is an industrial flue gas One of the ideal equipment for pollution control, it is widely used in acid removal and fog removal in various industrial production processes. Especially with the deteriorating quality of my country's atmo...

Problems solved by technology

[0006] The present invention aims at the shortcomings of the dust collection plate of the wet electrostatic precipitator, especially the problems of uneven water film and poor cleaning effect as the height of the dust collection plate increases, and proposes a new structure of the dust collection plate. In order to improve the function of the dust collection plate and increase the height of the dust collection plate, at the same time, ensure that the cleaning water film of the dust collection plate covers evenly, improve the cleaning effect and save investment
