Description

Electrostatic dust collection module group

Technical Field

The invention relates to the field of air purification, in particular to an electrostatic dust collection module group.

Background

The electrostatic dust collector utilizes DC high voltage electric field to make the micro dust and germ in the air collide with high voltage electric ion to make it carry negative charge when passing through high voltage discharging electric field, and then the micro dust and germ are adsorbed on the surface of the fin of the positive electric field according to the physical principle of positive and negative attraction when passing through the positive electric field of post dust collection, thus realizing the function of air purification.

At present, in some industry and civilian dust removal field, use the mode preparation electric field of sheetmetal and metal (conductive coating) tectorial membrane when adopting single electric field and two electric field modes to the equipment that adopts the high voltage static mode to remove dust, wherein the electric field can take place the discharge arc between the electrode because of the characteristic of adsorbed material and air, the dust collection effect obviously descends when this electric arc takes place can cause purifying effect to obviously descend and the amount of wind, can discover the obvious gradual decay of dust collection effect in the later maintenance along with the lapse of time, thereby lead to the general popularization of electrostatic precipitation mode, reuse and environmental protection requirement all receive obvious restriction.

Therefore, the reduction of discharge arc and the improvement of corrosion resistance of the surface of the dust collecting sheet for easy cleaning and reduction of attenuation are problems to be solved when the electrostatic dust collection is promoted.
