Optimized structure of dust collection plates, anode system and flexible wet electrostatic precipitator

Abstract

The invention discloses a dust collection pole plate optimizing structure, an anode system and a flexible wet type electric precipitator. The dust collection pole plate optimizing structure comprises a pulling device arranged on vertical columns surrounding a dust collection pole plate, and limiting devices matched with the vertical columns. The side face of each vertical column is provided with a plurality of longitudinal grooves so that flexible pole plates can be inserted into. The pulling device is arranged between the vertical column adjacent to a wallboard and the wallboard, and comprises a connection rod, one end of the connection rod is connected with the wallboard, the other end of the connection rod has an additional width relative to a connection rod body so as to be clamped into the longitudinal grooves of the corresponding vertical column, and rigid pulling is achieved. Each limiting device comprises a connector, the upper end of the connector is provided with a protruding column body capable of being inserted into the center of the corresponding vertical column, the lower end of the connector is provided with a plurality of clamping grooves, and flexible inserting is achieved. The performance of the flexible pole plates can be improved from multiple details, the phenomena that voltage of an electric field flashovers, and the dust collection pole plate is punctured are avoided, and accordingly, the dust collection efficiency is improved.

Description

technical field [0001] The invention relates to an optimized 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 pr...

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] In addition, because the pulling device on the column around the dust collection plate is a flexible part, the tension performance of the flexible part will be weakened after long-term use, resulting in the reduction of the discharge distance between the surrounding flexible plate and the cathode, frequent voltage flashovers, and the shock of the dust collection plate. Wear, affect the dust removal efficiency and other phenomena

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