Embodiment Construction

[0018] refer to figure 1 , figure 2 , image 3 It is an embodiment of a screening electrostatic precipitator of the present invention, a screening electrostatic precipitator, which sequentially includes an inlet horn 3, a conventional electric field 4, a screening electric field 5 and an outlet horn 6 along the flue gas flow direction, and the screening electric field 5 Including the cathode part 8 and the anode part 9, both of the cathode part 8 and the anode part 9 are steel wire mesh, which are called the cathode steel wire mesh and the anode steel wire mesh in order to distinguish them, but their basic structure is the same as that of the anode plate and the smoke of the conventional electrostatic precipitator. The gas parallel arrangement is different. The steel wire mesh of the cathode part 8 and the anode part 9 of the device is perpendicular to the flow direction of the flue gas. The flue gas needs to pass through the small holes of the steel mesh. Steel wire mesh i...

Abstract

The invention discloses a screening electric precipitator which sequentially comprises an inlet horn, a conventional electric field, a screening electric field and an outlet horn in the flue gas flowdirection. A flow guide dust collection device is arranged in the inlet horn, the screening electric field comprises a cathode and an anode which are both steel wire nets, and the cathode and the anode are both perpendicular to the flue gas flow direction. The screening electric precipitator has the advantages that the two electric fields of different structures are used for removing dust in a graded mode, the conventional electric field removes most dust, the screening electric field removes ultrafine-particle dust, flue gas of the screening electric field perpendicularly penetrates through acathode steel wire net and an anode steel wire net, secondary dust flying caused by vibration and beating is avoided, and the dust driving speed is effectively improved.

Description

technical field [0001] The invention relates to a screening electric dust collector. Background technique [0002] Particulate matter emitted by coal-fired power plants includes PM 2.5 Primary fine particles, condensable particles and mist droplets containing soluble salts are one of the important causes of severe haze in recent years. With the full implementation of ultra-low emissions from coal-fired power plants in my country, dust emission requirements have been basically met, but Conventional dry electrostatic precipitators are still unable to achieve 10mg / m under low energy consumption conditions 3 following steady discharge. [0003] Existing electrostatic precipitators have the following defects: [0004] 1. Existing electrostatic precipitators generally adopt the pole-matching type of "plate-pole line", and the plate arrangement is parallel to the direction of flue gas flow. This structure has obvious secondary dust, and the dust needs sufficient driving speed to ...
