Problems solved by technology

[0002] The electrostatic precipitator usually includes a corona electrode and a dust collection plate. The dust collection plate will continuously collect dust during the dust removal process of the electrostatic precipitator, and then remove it by rapping and water washing at regular intervals. Dust collected on the surface of the dust collection plate, otherwise it will seriously affect the dust removal efficiency of the electrostatic precipitator
However, the existing dust collecting boards are all made of metal materials with no gaps on the surface for collecting dust, which results in the existing dust collecting boards having a low ability to store dust and needing to be cleaned more frequently
In addition, due to the flat and smooth surface of the dust collection plate, its ability to capture tiny dust is low, which directly leads to the unsatisfactory dust removal efficiency of the existing electrostatic precipitator for removing particles with an equivalent diameter less than or equal to 2.5 microns

Embodiment Construction

[0017] Such as figure 1 and figure 2 As shown, the composite dust-collecting plate for electrostatic dust removal of the present invention includes a dust-collecting electrode 1 made of conductive material, and the dust-collecting electrode 1 is preferably made of metal materials such as stainless steel, aluminum, copper, etc., and the dust-collecting electrode 1 The surface is provided with a dust-absorbing layer 2 made of a filamentous or porous material, and the electrical conductivity of the filamentous or porous material constituting the dust-absorbing layer 2 is 1×10 -8 S / m—1×10 -5 S / cm. It is particularly emphasized that the electrical conductivity of the filamentous or porous material constituting the dust-absorbing layer 2 can only be 1×10 -8 S / m—1×10 -5 S / cm, the reason is that if the dust-absorbing layer 2 is made of metal wire, so that the dust-absorbing layer 2 can be completely conductive as a conductor, then because the electrostatic charge will tend to be ...

Abstract

A composite dust collecting plate for electrostatic dust collection comprises a dust collecting electrode (1) made of conductive materials, and a dust suction layer (2) made of silk-shaped or porous materials is arranged on the surface of the dust collecting electrode (1); and the conductivity of the silk-shaped or porous materials for forming the dust suction layer (2) is 1*10<-8>S / m to 1*10<-5>S / m. According to the composite dust collecting plate for electrostatic dust removal, the dust containing capacity is high, the time period needing by dust cleaning is long, the efficiency of cleaning particles with the equivalent diameter smaller than or equal to 2.5 micrometers is high, and the dust removal performance is very stable.

Description

technical field [0001] The invention relates to a composite dust collecting plate used for electrostatic dust removal. Background technique [0002] The electrostatic precipitator usually includes a corona electrode and a dust collection plate. The dust collection plate will continuously collect dust during the dust removal process of the electrostatic precipitator, and then remove it by vibration, water washing, etc. at regular intervals. The dust collected on the surface of the dust collecting plate will seriously affect the dust removal efficiency of the electrostatic precipitator. However, the existing dust collecting boards are all made of metal materials with no gaps on the surface to accommodate dust, thus causing the existing dust collecting boards to have a low ability to store dust and require a higher frequency of cleaning. In addition, because the surface of the dust collecting plate is relatively flat and smooth, its ability to capture tiny dust is low, and thi...
