Phase mutual friction between it, to form triboelectrification, electrification, the entirety of particulate matter being charged by friction through insulated particle container
Vibration or partial vibration realize enhancing triboelectrification effect, or to magnetic-particle impose transformation electric field magnetic field realization rub
The enhancing of electric effect.
Further, it is migrated by the dynamic in the work process of particulate matter, realizes that the update of charged insulating particulate matter is replaced
It changes, it is kept to filter adsorption capacity.
The principle of the present invention is to provide a kind of gas filtration medium, is mainly characterized by the filtering material liquidation used,
Filtering material is insulating materials, is contacted with each other between material granule, and there are mutual friction of motions, can also be deposited between particle and structure
It is rubbing, to enhance the amount of being charged by friction, gas is realized by the hole changed between particle or between particle and filtered, in gas
On-gaseous compound matter is attached to particle surface, and institute's static electrification further enhances the adsorption capacity of particle, realizes particulate matter
Filtering removal, meanwhile, particulate matter constantly moves update, realizes the maintenance of filtering material adsorption capacity and is removed going for object
It removes.
The beneficial effects of the present invention are：The present invention provides a kind of method of charged insulating particle filtering gas, by adopting
The problem for taking filtering hole and medium continually changing mode effective solution sorbing material absorption property to stablize.Gas passes through
The hole changed between intergranular texture or particle realizes filtering, and on-gaseous compound matter is attached to particle surface in gas, institute
Static electrification further enhances the adsorption capacity of particle, realizes the filtering removal of particulate matter, meanwhile, particulate matter constantly moves more
Newly, it realizes the maintenance of filtering material adsorption capacity and is removed the removal of object.
The present invention solves the problems, such as to be limited to be limited to be removed the specific resistance of substance, and activity in high-pressure electrostatic precipitation
The problem of charcoal adsorption capacity is saturated, dust removal and filtration ability is not limited by this two kinds of problems.It is suitable for industrial dedusting and purification
The multiple fields such as haze air use.
