Become high voltage electric field；When gas enters dedusting module by the passage on outer housing 3, dust granules can by with
The cleaner unit 4 of electrostatic, agitator 5 or outer housing 3 adsorb, it is achieved purify the purpose of gas.This structure
The high voltage electric field produced keeps several hours the most several days, the electric charge that agitation once produces, it is sufficient to for the longest
Dust-filtering in a period of time；Therefore, agitator 5 is not required to continuous firing, but intermittently stirs
Mix, within such as three days, be sufficiently stirred for once, once stirring 30 minutes.Have only to periodically start agitator 5
Once, gas dust-removing device gets final product continuous firing a period of time, can realize the suction of dust in gas in stirring
Attached, it is only necessary to the electric energy providing little can realize the adsorption cleaning to gas, and energy resource consumption is few, is cleaned into
This is low；Gap between cleaner unit 4 is more, and gas can easily pass through, and dedusting module is to gas stream
The resistance of movable property life is the least, negligible.
Alternatively, described air inlet 12 or gas outlet 11 connect blower fan 2.Blower fan 2 is utilized to drive gas warp
Cross cabinet 1, and by the dedusting module adsorption cleaning in cabinet 1, purified gas is discharged the most at last.
Alternatively, described air inlet 12 connects blower fan 2, and described gas outlet 11 is by being opened in described cabinet 1
On some passages constitute；Passage is: circular hole, square hole, slotted hole or gap structure.Such as Fig. 1 institute
Showing, blower fan 2 is arranged at air inlet 12, can be pumped into constantly in cabinet 1 by ambient atmos；Gas outlet
11 region be directly facing the environment such as indoor, so only need to offer some passages on cabinet 1, after purification
Gas is directly discharged in the environment residing for cabinet 1 through passage.
This utility model makes to produce between cleaner unit 4 or between cleaner unit 4 and outer housing 3 electricity by agitation
Son transfer, makes cleaner unit 4 or the upper electrostatic of outer housing 3 band, thus realizes the dust in the gas of process
The absorption of grain；Be not required to during work by plus high-voltage field provide corona ionized gas make dust granules charged and
Absorption Charged, and mainly make the cleaner unit 4 in dedusting module or outer housing 3 surface by friction
Produce electrostatic, the dust granules in adsorbed gas, thus realize purifying the purpose of gas.Have only to periodically open
Opening driving motor and stir a period of time, can realize the absorption of dust in gas, agitator is without leaving for a long time
Open, it is only necessary to the electric energy providing little can realize the adsorption cleaning to gas, and energy resource consumption is few；Electric field quilt
After consuming, it is again started up agitator 5 and can regenerate electric field, it is not necessary to change dedusting module or dust suction list
Unit 4, purifies low cost；Gas is not had between cleaner unit 4 and between cleaner unit 4 and outer housing 3
, the most there is not the ozoniferous phenomenon of product, do not result in secondary pollution in the phenomenon being ionized；Dust suction list
There is gap between unit 4, gas can easily pass through, and the resistance that gas flowing is produced by whole device is non-
The least, negligible.
Different embodiments can be combined into according to claim of the present utility model, but according to this utility model
Embodiment be only used for this utility model being illustrated and this utility model can't being caused restriction.
Obviously, those skilled in the art can carry out various change and modification without deviating from this reality to this utility model
By novel spirit and scope.So, if these amendments of the present utility model and modification belong to this practicality newly
Within the scope of type claim and equivalent technologies thereof, then this utility model is also intended to comprise these changes and become
Including type.
