Description

Technical Field

[0001] The invention relates to the technical field of electrostatic precipitator, and in particular to a micro-electrostatic precipitator. Background Art

[0002] Practice has shown that when a certain thickness of dust layer is attached to the dust collecting electrode and the corona electrode during the use of the electrostatic precipitator, the dust removal effect of the electrostatic precipitator is significantly reduced. Especially on the corona electrode that can generate a large number of ionized electrons, the attached dust will affect the normal operation of the corona electrode teeth, so it is necessary to clean the area.

[0003] In the prior art, there are two ways to clean the corona pole teeth: rapping and brush cleaning. The disadvantage is that when rapping is used for cleaning, dust can fall off the corona pole teeth under the action of rapping. However, secondary dust raising cannot be avoided. The secondary dust raising leaves the electric field and directly enters the atmosphere, affecting the dust removal efficiency of the electrostatic precipitator. At the same time, multiple rapping will seriously affect the assembly accuracy of the corona pole teeth and the service life of the equipment. In addition, at the tip of the corona pole teeth, due to the maximum electric field intensity, the tip dust is easy to form lumps, which are not easy to remove by rapping. When the brush is used for cleaning, friction is generated between the brush and the corona pole teeth, resulting in serious wear of the brush and a short service life. At the same time, the lumps formed by the dust at the tip of the corona pole teeth cannot be solved. Since the number of corona pole teeth in the electrostatic precipitator is relatively large, it is not easy to clean the lumps formed at the tip of the corona pole teeth by rapping and brush cleaning multiple corona pole teeth, and the dust removal efficiency is relatively low.
