Pocket type water distribution flushing system and method for cleaning pole plate

Abstract

The invention discloses a pocket type water distribution flushing system and method for cleaning a pole plate. The system comprises flexible fabric I and flexible fabric II which are arranged on the two sides of the flexible pole plate. The flexible fabric I, the flexible pole plate and the flexible fabric II are connected together so that the flexible fabric I and the flexible fabric II can forma pocket structure. Multiple water flowing passageways parallel in the vertical direction are arranged on the surface of the flexible fabric I and the surface of the flexible fabric II. A drilled flushing water pipe above the flexible pole plate is wrapped with the flexible fabric I and the flexible fabric II. Multiple drainage holes are formed in the bottom of the drilled flushing water pipe. When the pole plate is cleaned, flushing water is drained from the drainage holes in the bottom of the drilled flushing water pipe and is uniformly distributed to the surface of the flexible pole plate along the water flowing passageways, and a uniform flushing water film is formed. By the adoption of the pocket type water distribution flushing system and method for cleaning the pole plate, uniform distribution of the flushing water film on the surface of the pole plate can be improved effectively, channeling formed on the surface of the dust suction pole plate is lowered and eliminated, and thesurface of the pole plate is prevented from forming the scaling surface.

Description

technical field [0001] The invention belongs to the field of cleaning polar plates, and in particular relates to a pocket-type cloth water rinsing system and method for cleaning polar plates. 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 uses liquid to flush the surface of the dust collector to clean the dust, which can effectively collect fine particles (PM 2.5 Dust, SO 3 acid mist, aerosol), heavy metals (Hg, As, Se, Pb, Cr), organic pollutants (polycyclic aromatic hydrocarbons, dioxins), etc. [0003] As we all...

AI Technical Summary

Problems solved by technology

After the electrode plate of the wet electrostatic precipitator is changed to non-metallic and corrosion-resistant alloy steel, the corrosion of the electrode plate has been effectively controlled, but the anti-fouling of the electrode plate has not been completely solved. The reason is that the structure of wet electric washing is not perfect. At present, the plate is cleaned mainly by increasing the number of nozzles, increasing the amount of flushing water or the frequency of flushing. The surface of the plate forms a "channel flow" instead of a uniform water film. The amount of flushing water is large, the energy consumption of flushing is high, and the flushing is not thorough. The voltage also affects the moisture removal efficiency and other issues
