Go out, just obtain the air of pure and fresh cleaning through one-level demister except mist.
Use this device, the sky that gathers dust has been escalated in the face of gathering dust in tradition electric cleaner
Between so that the region gathered dust becomes a three-dimensional space from a two-dimentional plane, makes dedusting
Efficiency is greatly improved.Use this device, make metal gather dust net weight greatly alleviate.
Owing to have employed the metal net that gathers dust as dust collector pole, this device is not suitable for processing containing acid
Property the more flue gas of composition, it is to avoid because the effect of corrosion is by steel wire eating thrown.
According to of the present invention. the preferred version of wet electrostatic air deduster, metal is received
The online shape of a mesh of dirt is provided in round or hexagon.
Wet electrostatic air deduster of the present invention provides the benefit that: the present invention will pass
A space of gathering dust has been escalated in the face of gathering dust in system electric cleaner so that the region gathered dust is from one
The plane of individual two dimension becomes a three-dimensional space, makes efficiency of dust collection be greatly improved；With
Time due to device inner rotation, rotation process adds the disturbance of gas-liquid interface, promotes
Pollutant or toxic gas are absorbed；Meanwhile, the gather dust top of net of every layer of metal is equal
It is provided with charged annulus, adjacent charged annulus is set to the electric charge of opposed polarity, for inner chamber
Room produces an alternation repeatedly, has the electric field of strong turbulating effect, by increasing capacitance it is possible to increase a grit
Turbulent flow, further enhance inside transport phenomenon, add drop catch granule probability,
The most also the electric field trapping effect to granule is increased so that dust collection effect is greatly improved；This
Bright fully utilizing charged dedusting technology, spray for dust suppression technology, charged water spray dedusting technology is mutual
Coupling comprehensive mass transfer theory intensified dust removal effect；Wet method filtration is used to effectively absorb in gas
Pollutant, simple in construction, processing cost is low, and efficiency is high, is with a wide range of applications,
Can be widely used in the field such as chemical industry, environmental protection, including large tunnel engineering, subway station, pit
The dedusting that production etc. are local, it is also possible to for public arena, the even air cleaning in family.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described specifically, but the enforcement of the present invention
Mode is not limited to this.
Seeing Fig. 1 to Fig. 4, wet electrostatic air deduster, including line shell 5, cover plate
7 and water-collecting tray 11；Described cover plate 7 is arranged on the top of line shell 5；Water-collecting tray 11 is arranged
Bottom at line shell 5；Rotary shaft 1 is had centrally along axially arranged, this rotation at line shell 5
Rotating shaft 1 is by motor-driven rotation；Multiple deep bead 4 it has been disposed radially in line shell 5,
This deep bead 4 is installed in rotary shaft 1；In line shell 5, circumferentially face is provided with multilamellar gold
Belong to and gathering dust net 3, described metal gather dust net 3 by line shell 5 internal chamber 10 by different radii
It is divided into multilamellar；The gather dust top of net 3 of every layer of metal is provided with charged annulus 2, adjacent lotus
The electric charge of opposed polarity it is connected with on electricity annulus 2；Horizontally disposed in the bottom of line shell 5
Having sealing plate 6, gather dust with the outermost metal radius of net 3 of the radius of sealing plate 6 is consistent,
Described metal gathers dust net 3 and deep bead 4 extends axially downward and fixes with sealing plate 6；Institute
Stating and be provided with into water air inlet 8 on cover plate 7, this water inlet air inlet 8 is positioned in cover plate 7
Heart position；The side of water-collecting tray 11 is provided with gas outlet 12；The bottom of described water-collecting tray 11
It is provided with outlet 13.
In a particular embodiment, the charged voltage charged annulus 2 arranged can not be received more than metal
Breakdown voltage between dirt net 3, within breakdown voltage, measures efficiency of dust collection and institute's making alive
Relation, choose efficiency of dust collection peak as running voltage.
The metal shape of a mesh arranged on net 3 that gathers dust needs to ensure when fluid flows through wherein
Resistance is minimum, also easily forms more stable moisture film on wire netting simultaneously, can select shape
The circle of shape regular uniform or hexagon etc..
It is interior that dusty gas and water are simultaneously into device by water inlet air inlet 8 by the present invention
Layer chamber；Motor drives rotary shaft to rotate, and rotary shaft drives deep bead 4 and metal to gather dust net 3
Also rotate.Will be with rotating owing to being provided with deep bead 4, air-flow and water, be greatly reinforced
Internal transport phenomenon, adds the disturbance of gas-liquid interface in rotation process, promotes dirt
Dye thing or toxic gas absorb；Meanwhile, because in centrifugal action and line shell 5
The effect of the sealing plate 6 arranged, makes gas and water can only spread to the direction away from the center of circle, expands
During Saning, water is uniformly distributed by the hole that metal gathers dust on net 3, gathers dust net 3 at metal
Surface forms one layer of uniform moisture film, and this layer of moisture film can carry out filtration to gas.If adopted
With higher rotating speed, and abundant metal gathers dust net, and this wet method filtration enables to
PM2.5 removes the efficiency reaching the highest.Further, carry to the water spread away from direction, the center of circle simultaneously
Walk metal to gather dust the dust that net 3 collects above.Meanwhile, the gather dust top of net of every layer of metal is equal
It is provided with charged annulus 2, adjacent charged annulus is set to the electric charge of opposed polarity, for inside
Chamber 10 produces an alternation repeatedly, has an electric field of strong turbulating effect, it is possible to increase
Add the turbulent flow of grit, further enhance the transport phenomenon of inside, add drop and catch granule
Probability, the most also increase the electric field trapping effect to granule so that dust collection effect greatly carries simultaneously
High.Owing to gas is gradually purified, when gas is diffused into outermost metal by the metal net 3 that gathers dust
During the region 9 that the net that gathers dust is constituted with line shell 5, all purify as clean gas, clean gas
Flowing out from gas outlet 12, remove the water smoke in air by peripheral hardware demister, dust-containing water is from going out
The mouth of a river 13 is got rid of, and can select discharge according to practical situation or recycle.
