Fixed structure of dust collecting plate, anode system and flexible wet electrostatic precipitator

Abstract

The invention discloses a dust-collecting pole plate fixing structure, an anode system and a flexible wet electrostatic dust remover. The dust-collecting pole plate fixing structure comprises a limiting device matched with a vertical column or / and a fixing device on a dust-collecting pole plate, wherein a plurality of longitudinal grooves are uniformly formed in the side surface of the vertical column so as to insert flexible pole plates; the limiting device comprises a connector; a convex column body capable of being inserted into the cavity of the vertical column is arranged at the upper end of the connector and a plurality of clamping slots are formed in the lower end of the connector so as to achieve flexible insertion; the fixing device comprises parallel clamping plates arranged on the two sides of the flexible pole plates, and a plurality of tightening components which are distributed along the clamping plates at intervals and clamp the flexible pole plates and flexible components on the inner side of the dust-collecting pole plate, so that close fit between the clamping plates and the flexible pole plates is achieved.

Description

technical field [0001] The invention relates to a fixed structure of a dust collecting pole plate, an anode system and a flexible wet electric dust collector. Background technique [0002] Wet electrostatic precipitator is an environmental protection equipment used to remove liquid droplets, aerosols, PM2.5 and other harmful substances carried in wet flue gas. It is an ideal equipment for controlling flue gas dust pollution. As thermal power plants and steel mills reach ultra-low emission standards and energy-saving renovations, wet electrostatic precipitators are increasingly used. Wet electrostatic precipitator is divided into rigid plate, flexible plate and glass fiber reinforced plastic wet electrostatic precipitator according to the dust collecting plate. Among them, the flexible wet electrostatic precipitator uses excellent organic fibers as the anode dust collecting plate, and the "nearly zero water consumption" and "zero alkali consumption" water film in the process...

AI Technical Summary

Problems solved by technology

For example, the flexible wet electrostatic precipitator dust collection plate fixing device and flexible wet precipitator provided by the invention patent 201610819283.1, however, the anode lower flower plate of this kind of flexible wet precipitator has certain incompatibility in the process of manufacturing, and the lower flower plate The plate is assembled and welded by frame channel steel, internal criss-cross flat steel, and limit round steel (column). The welding workload is large, the economic cost is high, and there is local corrosion at the welding place between the flat steel and the cylinder in a wet smoke environment. Phenomenon

[0004] At the same time, when the anode system is flushed, there is a distance directly below the clamping point of the dust collection plate and the flexible plate, and a uniform water film cannot be formed. The gap between the splint and the flexible plate and the two ends of the splint form a large water flow, which is prone to splashing , a uniform water film cannot be formed on both sides of the flexible plate, resulting in poor cleaning effect, frequent flashover of electric field voltage, and obvious decline in dust removal efficiency.

[0005] In summary, the structural design of the current flexible wet electrostatic precipitator has problems that may cause frequent voltage flashovers, breakdown of the dust collection plate, and affect the efficiency of dust removal, which urgently needs to be improved.
