Description
Technical field
The utility model relates to a kind of electrostatic dust-collecting device, espespecially a kind of electrostatic dust-collecting device of scroll-type structure.
Background technique
The basic principle of electrostatic precipitation is that identical charges repel each other and principle of opposite sex attraction by applied voltage and using charge, is formed
Two opposite polarity electric fields, that is, make air ionization by principle of corona discharge, the particle in gas to be processed via from
Son hits and charges, and shifts to collecting plate and remove from gas to be processed, reaches the purpose of purification gas.
Secondary person, electrostatic precipitation is mostly used for industrial use at present, and the public places such as general house, office or medical institutes are not
It is more, although there are many gas branner type on the market, the branner of PM2.5 and few can be effectively removed, this is because of electrostatic precipitator
The time that dirt needs larger dust to contact with electrode, therefore it is more difficult to reach Miniaturization Design.In addition, at present it is industrial or
General commercially available electrostatic dust arrester reaches the effect for the time that increase dust is contacted with electrode mostly with flat or honeycomb structure
Fruit, so either flat or honeycomb structure.
