Problems solved by technology

However, at present, the dust collection plates of the plate-type wet electrostatic precipitator are arranged in a "one" shape to form a straight channel, and the dust collection plates of the honeycomb wet electrostatic precipitator are surrounded by a "hole" channel. The main problems of the two are: The included angle between all the dust collecting plates and the flue gas flow direction is 0 degrees, and the turbulence of the air flow is relatively smooth, so the agglomeration and growth of the dust are restrained to a certain extent, and the dust can only be captured by the electric field force, and the inertial force of the particles has not been effectively utilized. , and the honeycomb wet electrostatic precipitator dust collection plate consumables are relatively large

Embodiment 1

[0028] An anode plate, the surface of the anode plate is provided with at least one protrusion, and the protruding direction of the protrusion is perpendicular to or intersects with the direction of the flue gas flowing through the anode plate to form a set angle, so as to improve the turbulence of the flue gas; the flue gas passes through The protrusions on the protruding anode plate can effectively cause the turbulent flow of the flue gas, which is beneficial to the dispersion of the flue gas and contributes to the effect of dust removal on the flue gas.

[0029] The shape of the anode plate may be a continuous S-shape, and each protrusion may be in the shape of a trapezoid.

Embodiment 2

[0031] A wet electrostatic precipitator, comprising a housing, the housing is provided with a flue gas inlet 1 and a flue gas outlet 6, an air distribution device 2 is arranged at the flue gas inlet 1, an anode dust collection system 8 is arranged in the housing, and the anode collection The dust system 8 includes a plurality of anode plates set at intervals, and the surface of the anode plate is provided with at least one protrusion. When there are multiple protrusions on an anode plate, adjacent protrusions are separated by a set distance; The protruding direction is perpendicular to or intersects the direction of flue gas flowing through the anode plates to form a set angle to improve the turbulence of the flue gas. A cathode system 9 is arranged between every two adjacent anode plates; the flue gas enters the shell In the body, the flowing flue gas flows through the anode plate, and the turbulence of the flue gas is caused by the protrusions, which is conducive to the unifo...

Embodiment 3

[0042] The difference between this embodiment and embodiment 2 is:

[0043] Both the flue gas inlet and the flue gas outlet are arranged in a vertical position.

Abstract

The invention discloses an anode plate and a wet electric precipitator. The electric precipitator comprises a casing, wherein the casing comprises a smoke inlet and a smoke outlet; an anode dust collecting system is arranged in the casing and comprises multiple anode plates spaced by set distances; at least one bulge is arranged on the surface of each anode plate, and the protruding direction of each bulge and the flowing direction of smoke flowing through the anode plate are perpendicular to each other or intersect with each other to form a set angle, so that the turbulent effect of the smoke is improved; and a cathode system is arranged between every two adjacent anode plates. The bulges are arranged on the anode plates, and the protruding directions of the bulges and the flowing direction of smoke flowing through the anode plates are perpendicular to each other or intersect with each other to form the set angle, so that the turbulent effect of the smoke is improved, coagulation of the smoke is improved, meanwhile, the smoke is trapped under the inertia effect, the dust removal efficiency of the precipitator can be remarkably improved, and energy is saved; and the bulges are arranged on the anode plates, the multiple bulges are aligned one by one, and thus, the smoke can be balanced and can be uniformly distributed in an electric field area of the casing.

Description

technical field [0001] The invention relates to flue gas dedusting equipment, in particular to an anode plate and a wet electric dust collector. Background technique [0002] Electrostatic precipitator is a relatively economical and most effective method to reduce flue gas and dust emissions in coal-fired power plants, metallurgy and cement industries. The technical route of the dust collector. At present, wet electrostatic precipitators include plate wet electrostatic precipitators and honeycomb electrostatic precipitators. [0003] The wet electrostatic precipitator is used after wet desulfurization and before the smoke outlet to remove the smoke and dust in the flue gas to achieve ultra-low emission of smoke and dust. However, at present, the dust collection plates of the plate-type wet electrostatic precipitator are arranged in a "one" shape to form a straight channel, and the dust collection plates of the honeycomb wet electrostatic precipitator are surrounded by a "h...
