The two ends of dust collecting electrode 22 of hollow cylinder shape linked into an integrated entity by mending plate 26 respectively.
The dust collecting electrode of hollow cylinder shape can also be one.
As Fig. 1, support 21 are fixed on the housing 10 or mended on plate by seal 15, mend plate and fix（As welded）
Plate is mended on housing 10, in the present embodiment by metal is made.
Such as Fig. 4, in another embodiment, the dust collecting electrode of hollow cylinder shape is have reeded collecting plate 50 respectively by two
Connect and compose.Groove shapes are semicircle or polygonal half, have three semicircles on two collecting plates in figure respectively
Connected in star, the depression direction of three semi-circular recesses is identical, and formation three is hollow after so the two collecting plates link together
The dust collecting electrode of cylinder.In addition, the gap between two neighboring dust collecting electrode is equally filled and led up with plate.
As Fig. 1, the both sides of housing 10 have air inlet 11 and air outlet 12 respectively, electric field arrangement 20 is upper and lower interior with housing 10
Form upper air duct 13, lower air duct 14 between surface respectively, upper air duct 13, lower air duct 14 respectively with air inlet 11 and the phase of air outlet 12
Logical, the position in upper air duct 14 respectively close to air inlet 11 and air outlet 12 sets the first air-valve 31, the second air-valve 32, lower air duct
Position in 14 respectively close to air inlet 11 and air outlet 12 sets the 3rd air-valve 33, the 4th air-valve 34.First air-valve 31, second
Air-valve 32, the 3rd air-valve 33 and the 4th air-valve 34 are fixed on the inwall of housing 10, are preferably welded.
First air-valve 31, the second air-valve 32, the 3rd air-valve 33 and the 4th air-valve 34 are used for controlling by the gas of electric field arrangement
The direction of stream, specially：When the first air-valve 31, the 4th air-valve 34 are opened, when the second air-valve 32, the 3rd air-valve 33 is closed, waste gas
From air inlet 11 enter after after upper air duct 13, air-flow from top to bottom by electric field arrangement, then through lower air duct 14 from air outlet 12
Discharge, wind wheel is moved downward in the process.When the first air-valve 31, the 4th air-valve 34 are closed, the second air-valve 32, the 3rd air-valve 33
During unlatching, waste gas from air inlet 11 enter after after lower air duct 14, air-flow from the bottom to top by electric field arrangement, then through upper air duct 13
Discharged from air outlet 12, wind wheel is moved upwards in the process.Therefore can very easily be changed by electricity by control valve
The direction of the waste gas of field device so that wind wheel can be moved from top to bottom and moving back and forth from the bottom to top, so that thoroughly
Clean dust.
Such as Fig. 1, spray equipment 40 is provided with upper air duct 13, spray equipment 40 fixes interior table on the housing 10 in the present embodiment
On face, spray equipment 40 can to electric field arrangement 20 spray cleaning fluid, on wind wheel sweep dirt device clean dust collecting electrode inwall on
During dust, opening spray equipment can further clean out of dust.In addition, spray equipment 40 is only as a kind of preferred side
Case, the waste gas that purify as needed in practice chooses whether to need to install spray equipment, for example, need the waste gas of purification
In the greasy dirt containing recoverable, if can be polluted to the greasy dirt for purifying using spray equipment.
The utility model proposes the electrostatic precipitator with automatic clearing function, waste gas when by electric field arrangement, gas
Stream can drive wind wheel to rotate, and wind wheel can move up and down while rotating along corona bar so that wind wheel is from hollow cylinder shape
Dust collecting electrode inside pass through, and now the dirt device of sweeping on wind wheel follows wind wheel to rotate to clean out the powder on dust collecting electrode inwall
Dirt, the so electric field arrangement in time can also fall the dust cleaning on dust collecting electrode inwall while waste gas is purified, so that
Obtaining the electric field arrangement has the function of automatic cleaning, without using manual cleaning, has saved time and cost, and structure letter
It is single.In addition, changing air-flow can make wind wheel motion on corona bar up and down back and forth by the direction of the electric field arrangement, can be with
The dust on dust collecting electrode inwall is thoroughly cleaned out, compared to using non-secondary pollution is cleaned using solution, beneficial to environment.Wind wheel
It is engaged using internal and external threads mode between corona bar, also can be to corona while wind wheel is moved back and forth up and down on corona bar
Dust is cleared up on bar.
Specific embodiment above is only used to illustrate design of the present utility model, and one of ordinary skill in the art exists
Various deformation and change can be made under design of the present utility model, these deformations and change are included in guarantor of the present utility model
Within the scope of shield.
