A kind of industrial dedusting method using wet deposition, step are：

S1：Clean liquid water is filled to 260/ time back cavity of left chamber by reception pipe 240 first, will then be connect with rubber stopper The nozzle of closed tube 240 blocks, and starts water pumper 220, and water pumper 220 draws 260/ time back cavity of left chamber by drinking-water pipe 250 Interior clean liquid water is simultaneously delivered to water-supply-pipe 321 by outlet pipe 230, and liquid water is conveyed by water-supply-pipe 321, rotation pipe 323 To atomizer 324, a part of liquid water is become big water droplet and sprays to form the curtain of rain, another part liquid water by atomizer 324 Atomization sprays and forms cloud cluster by being atomized small water droplet in 330 inner cavity of cartridge filter, and remaining liquid water is by connecting tube 341, support Pipe, annular diversion pipe are sprayed by atomizer forms the second layer curtain of rain and second layer atomization cloud cluster；

S2：Start wind turbine 120 at this time, around own axis, impeller 140 will seal the output end impeller 140 of wind turbine 120 The air of shell inner cavity is blown into 311 inner cavity of reduction of speed shell by dust guiding tube 160, and the air pressure of capsul inner cavity reduces, and the external world carries powder The air of dirt enters capsul inner cavity by ventilation opening 130 under atmospheric pressure, and the sky of dust is carried into capsul inner cavity Under gas enters reduction of speed shell 311 under the action of impeller 140 by dust guiding tube 160 and the connecting hole on support plate 318a Chamber, air flow to upper chamber by lower chambers, and air is through passing through fan 312 and drives fan 312 around own axis, fan 312 drive rotation pipe 323 and connecting tube 341 around own axis, and rotation pipe 323 drives atomizer 324 to rotate, atomization spray Mouth 324 uniformly sprays big water droplet during rotation and is atomized small water droplet and is distributed in upper filtering chamber, and connecting tube 341 passes through branch Stay tube drives atomizer of the annular diversion pipe on own axis, annular diversion pipe with the cascade and mist of rotation injection Change the more uniform of cloud cluster distribution, the part kinetic energy of air is converted into the kinetic energy of fan 312, and the air of reduction of speed is flowed to by upper chamber It stops circular conical surface 315 and is hit under the guiding of guiding cambered surface 316 and stop circular conical surface 315, the flow velocity of air further decreases, and drops Air after speed enters upper filtering chamber by a guiding channel part, another part enters lower filter chamber by filter hole 332 The air pressure of Shi Bingshixia filtering chamber increases, and when filtering chamber is in high pressure instantly, the air that guiding channel is entered by upper chamber is complete Portion flows into upper filtering chamber；

S3：Air into upper filtering chamber collides the curtain of rain, and the dust in big water droplet absorption air in the curtain of rain simultaneously hits obstruction Circular conical surface 315 and filter hole 332, hit stop circular conical surface 315 big water droplet along stop circular conical surface 315 inclined-plane flowing and It is fallen from the edge of obstruction circular conical surface 315 to filter hole 332 under the action of its own gravity, air carries remaining dust and bangs into atomization Cloud cluster, the small water droplet in adsorbing powder dust cloud cluster, since 324 sustained firing of atomizer is atomized small water droplet so that carry dust Small water droplet, which increases and mutually collides, congeals into big water droplet, and flood drop is fallen under the effect of gravity is stopping the oblique of circular conical surface 315 On face or in filter hole 332, the flood for carrying dust drops in filter hole 332 and collects around and fell by filter hole 332 Filter chamber room simultaneously eventually falls into the intracavitary that flows back in right chamber 280/, and big water droplet falls into back cavity in right chamber 280/ from lower filtering chamber During the air with dust in lower filtering chamber can be also filtered；

S4：Preliminary filtered air is flowed into the inner cavity of secondary filter cylinder 345 by upper filtering chamber, and preliminary filtered air is met to second The layer curtain of rain and second layer atomization cloud cluster simultaneously form the big water droplet with dust, and the flood with dust drops in the effect of its own gravity It is lower to pass through secondary 345 inner cavity of filter cylinder, upper filtering chamber, filter hole 332, lower filtering chamber and eventually fall into 280/ last time of right chamber Intracavitary is flowed, the air of purification enters 347 inner cavity of dust-collecting cylinder across through hole, and air flows to two from the gap between collecting plate 346 At the top of secondary filter cylinder 345, the dust in air is trapped in the inflection point of collecting plate 346；

S5：Air enters through gas vent in gas cylinder 351, and air moves straight up along the inner cavity of gas cylinder 351, and air is hit It hits liquid collecting plate 353 and the external world is discharged by discharge orifice, the steam during air impact liquid collecting plate 353 in air is trapped in liquid collecting On plate 353, the steam on liquid collecting plate 353 gradually increases and is agglomerated into water droplet, and water droplet is detached from liquid collecting under the effect of gravity Plate 353 drips straight down, and water droplet is fallen by 351 inner cavity of gas cylinder, drainage tube 354, conducting endless tube 355,356 inner cavity of communicating pipe Enter back cavity within/on right chamber 280；

S6：Sewage with dust is gathered in right chamber 280/ intracavitary that flows back, and left chamber flows back for 260/ time in water pumper 220 During the purified liquid water of intracavitary extracts, the air pressure of 260/ time reflux intracavitary of left chamber reduces, and flows back in right chamber 280/ The sewage with dust of intracavitary enters to 260/ time reflux of left chamber through overpopulation strainer 270 under atmospheric pressure Chamber, the sewage with dust become the more liquid water of cleaning under the filtration of high density strainer 270 and by water pumpers 220 It is delivered to filter device 30 and completes water cycle.

The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, after knowing content described in the present invention, without departing from the principle of the present invention, it can also be made several Same transformation and replacement, these convert and substitute on an equal basis and also should be regarded as belonging to the scope of protection of the present invention.
