Polar plate for wet type electrostatic precipitator

Abstract

The invention relates to a polar plate for a wet type electrostatic precipitator. The polar plate comprises a current sharing tube (1) and a collecting plate (2) and has double characteristics of balanced distribution of washing water flows and uniform coverage of a polar plate water film. The polar plate is characterized in that the current sharing tube (1) is arranged at the top part of the collecting plate (2); the collecting plate (2) has a structure of double-layer symmetric concave-convex ripple surface and is shaped through a laser welding and bulging technology; concave surface welding spots on the collecting plate (2) are uniformly distributed in rows and lines in a stagger manner; with the combination of a non-spraying type polar plate washing mode such as dripping spraying or overflow spraying and the like and the adoption of the structure of the polar plate, flushing water can be uniformly distributed onto the two surfaces of the collecting plate (2) through the current sharing tube (1), and influence of the gravity to the water flows is overcome by utilizing the surface tension of water, so that a uniform washing water film is acquired. The polar plate for the wet type electrostatic precipitator has the remarkable advantages of balanced distribution of the water flows, uniform water film, good washing effect, stable electric field running and purification efficiency, great increase of rigidity and effective height of the polar plate, saved occupied places and investment and the like.

Description

technical field [0001] The invention relates to an internal key component of flue gas purification equipment in the field of environmental protection, in particular to a pole plate structure of a wet electrostatic precipitator. Background technique [0002] 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, aerosols, 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 count...
