A polar plate and a wet electrostatic precipitator for realizing uniform distribution of water film

Abstract

The invention discloses a pole plate with water film uniformly distributed and a wet electrostatic precipitator. The pole plate is composed of at least two pole plate areas. Sloping grains are arranged on the surfaces of the pole plate areas correspondingly and are parallel. The horizontal distances between the slopping grains are equal. The adjacent sloping grains on the surfaces of the two poleplate areas are opposite in direction. Angles formed by the sloping grains are acute angles formed between the sloping grains and the latitude line direction. According to the pole plate with the water film uniformly distributed and the wet electrostatic precipitator, surface characteristics of the pole plate of the wet electrostatic precipitator are improved, consumption of washing water is reduced, the water film is uniformly distributed under small water amount distribution conditions, and accordingly the efficient dedusting efficiency is guaranteed.

Description

technical field [0001] The invention belongs to the field of cleaning polar plates, and in particular relates to a polar plate and a wet electrostatic precipitator for realizing uniform water film distribution. Background technique [0002] In recent years, with the implementation of "ultra-low emission" transformation of pollutants in the whole country, wet electrostatic precipitators have been widely promoted and applied. Wet electrostatic precipitator is a new dust removal equipment used to deal with tiny dust and fine particles, mainly used to remove dust, acid mist, water droplets, aerosol, odor, PM in wet gas 2.5 It is an ideal equipment for controlling air dust pollution. The wet electrostatic precipitator is usually referred to as WESP, and the basic principle of dust removal is the same as that of the dry electrostatic precipitator. It relies on high-voltage corona discharge to charge the dust, and the charged dust reaches the dust collection plate / pipe under the a...

Problems solved by technology

The adverse effect of this is: in the process of engineering application, the water flow on the surface of the polar plate flows at a certain angle under the diversion effect of the texture. figure 1 As shown, it is difficult to form a water film covering the entire surface of the plate, and the area without water film coverage forms dust, which affects the dust removal efficiency

[0005] For a rigid plate, the surface of the plate is relatively smooth without the above-mentioned texture structure. However, due to the lack of diversion, water tends to form "branch"-shaped channels on the surface of the plate, and it is also difficult to form a channel that covers the entire surface of the plate. water film

[0006] Due to the surface physical characteristics of the above two plates, in actual engineering, a large amount of flushing water is required to form a water film covering the entire surface to complete dust removal, which increases the water consumption of wet electricity and its related electricity. consumption, alkali consumption, etc.
