Problems solved by technology

[0003] In the existing electrostatic precipitator, due to the large distance between the positive and negative plates, the particles with a diameter of less than or equal to 2.5 microns in the flue gas of the power plant have not had time to move in the air flow and adhere to the positive and negative plates. It is carried by the air flow through the positive and negative plates. If the speed of the air flow passing through the electrode plates is reduced, the air flow that the electrostatic precipitator can handle will be greatly reduced, and it is difficult to meet the processing requirements required for production.
Therefore, the existing electrostatic precipitator cannot meet the design requirements of removing very fine dust in the large flow gas. Particles that can enter the lungs

Embodiment Construction

[0020] like figure 1 and figure 2 As shown in the figure, the rotary disk type runoff electrode plate dust collector of the present invention includes a casing 1, and a dust gas duct 7 is arranged in the casing 1, and an electrode plate 3 whose plate surface can be ventilated is arranged in the dust gas duct 7. The electrode plate 3 The plate surface is located in the cross-sectional direction of the dust and gas duct 7, the electrode plate 3 is provided with a front discharge net 4 in front of the direction of the inlet end of the dust and gas duct 7, the plate surface of the electrode plate 3 facing the front discharge net 4 is a plane, and the electrode plate 3 It can be rotated in the dust and gas duct 7 under the driving of the prime mover 11. The plate surface of the electrode plate 3 facing the inlet end of the dust and gas duct 7 is always kept parallel to the mesh surface of the front discharge mesh 4 during the rotation process. The front discharge mesh 4 A potenti...

Abstract

The invention discloses a rotating disc type runoff lightning shield dust remover. The dust remover comprises a casing, wherein a dust air pipe is arranged in the casing; a disc-shaped lightning shield is arranged inside the dust air pipe; the disc surface of the lightning shield can rotate around the section of the dust air pipe; the circumferential surface of the lightning shield is in clearance fit with the inner wall of the dust air pipe; a front discharging net is arranged in front of the lightning shield towards the inlet end of the dust air pipe; the end surface of the lightning shield towards the front discharging net is parallel to the front discharging net; the lightning shield is made of porous foam metal plates, a plurality of parallel corrugated plates, honeycomb plates or silk nets; a potential difference is generated between the front discharging net and the lightning shield through the electric connection with a high-voltage direct-current power supply; a dust blowing pipe is arranged in the dust air pipe; the dust blowing opening of the dust blowing pipe is towards the disc surface of the lightning shield. The invention aims to provide the rotating disc type runoff lightning shield dust remover which has greater treated air quantity in the unit time and a prominent effect of removing fine dust comprising PM 2.5, is stable in dust removing performance, low in operation cost and long in service life.

Description

technical field [0001] The invention relates to a rotary disc type radial flow electrode plate dust collector. Background technique [0002] PM2.5 refers to particulate matter in the atmosphere with a diameter of less than or equal to 2.5 microns, also known as particulate matter that can enter the lungs. Although PM2.5 is only a very small component in the composition of the earth's atmosphere, it has important effects on air quality and visibility. PM2.5 has a small particle size, is rich in a large amount of toxic and harmful substances, and has a long residence time in the atmosphere and a long transportation distance, so it has a greater impact on human health and the quality of the atmospheric environment. Meteorological experts and medical experts believe that the haze weather caused by fine particles is even more harmful to human health than sandstorms. Particles with a particle size of more than 10 microns will be blocked out of the human nose; particles with a pa...
