Specific embodiment

Below in conjunction with the accompanying drawings the utility model embodiment is described further：

As illustrated, a kind of self-excitation bathing deduster, including casing 2, inside described casing 2, include the water positioned at bottom The inlet plenum 22 being separated with middle baffle plate 1 above room 21 and hydroecium 21 and air-purifying chamber 23；Described inlet plenum 22 side be provided with into Gas port 221, described air-purifying chamber 23 top is provided with gas outlet 231, and described gas outlet 231 connects escape pipe 14 by centrifugal blower 3； In described air-purifying chamber 23, the position near hydroecium 21 and middle baffle plate 1 is provided with the blade 4 of bending, is additionally provided with described casing 2 The lower blade 5 corresponding with blade 4, the bottom of described lower blade 5 is placed in hydroecium 21, and top is placed in air-purifying chamber 23, institute State the vortex channel 6 being formed between lower blade 5 and blade 4 in " S " type；It is additionally provided with some water fenders in described air-purifying chamber 23 On 7, and the inwall being fixed on middle baffle plate 1 and casing 2 of uniform crossover.

Its operation principle：When dusty gas enters inlet plenum 22 by air inlet 221, air-flow can clash into middle baffle plate 1 and turn Bend towards lower impact in the water surface of hydroecium 21, wherein partly larger particle drops in water；

Then the gas in hydroecium 21 then can be by being entered by the vortex channel 6 that blade 4 and lower blade 5 form " S " type Enter air-purifying chamber 23, when by vortex channel 6, substantial amounts of spray can be evoked, so that aqueous vapor is fully contacted, the fine dirt of the overwhelming majority Grain is mixed in water, and vortex channel can make whole flow direction change simultaneously, produces the relative fortune of necessary particle and drop Dynamic, form an effective dust removal process；

After leaving vortex channel 6 entrance air-purifying chamber 23, water fender 7 can block dust-loaded drop further, and after purifying Gas is discharged by escape pipe 14 by centrifugal blower 3.

It is not only simple in structure, and with respect to existing routine wet dust collector, more preferable dust removing effects can be obtained.

As illustrated, the free end of described water fender 7 is in downward bending setting so that water fender 7 can preferably block Dust-loaded drop, it is to avoid discharged together by centrifugal blower with gas, effect is more preferable.

As illustrated, being additionally provided with demisting plate 8 at the gas outlet 231 of described air-purifying chamber 23, by demisting plate 8, one can be entered Walk reaches except fog effect.

As illustrated, being provided with muffler 9 on described escape pipe 14, muffler 9 can eliminate or reduce gas from giving vent to anger The noise that pipe 14 produces when discharging, reduces noise pollution.

As illustrated, the bottom of described hydroecium 21 side is provided with blow-off pipe 10, described blow-off pipe 10 connects blowoff valve 11, After dusty gas is cleaned, its particle is eventually combined with the water in hydroecium 21, and falls into the bottom, by blow-off pipe 10 and blowdown Water-bed residual particles can effectively be cleared up by valve 11.

Further, the bottom surface of described hydroecium 21 is arranged to ramp structure, and towards the downward-sloping setting of blow-off pipe 10, Residual particles can be automatically biased towards blow-off pipe 10, and filth-discharging effect is more preferable.

In addition, being additionally provided with water box cover outside hydroecium 21, when blowdown cannot be cleared up completely using blow-off pipe, open water box cover Carry out cleaning to be convenient to.

As illustrated, described hydroecium 21 connects downflow weir 12, downflow weir 12 connects blow-off pipe 10 by overflow pipe 13, described The level height of downflow weir 12 is consistent with the level height of middle baffle plate 1 lower end, and the water surface of hydroecium 21 can be kept just to overflow Cross the bottom of middle baffle plate 1 so as to be maintained at optimum level of water.

Embodiment is not construed as the restriction to utility model, but any based on of the present utility model spirit improvements introduced, All should be within protection domain of the present utility model.
