 The dust concentration sensor 3 is used in real-time detection of the dust concentration in the working environment, and the signal processors of the dust concentration sensor 3 are connected to the induction solenoid valve 16, the dust removal power member 7, and the inductive solenoid valve 16 is used to control atomization. The start and stop of the nozzle 15. When the dust concentration is higher than 50mg / m 3 When the signal processor connected to the dust concentration sensor 3 and the dust-filled power member 7 will automatically open the interval 3 to 5 s, and the atomization nozzle 15 is pre-formed in the wetting chamber 14, dusting dust. The power component 7 then forms a negative pressure suction environment in the wetting chamber 14. Of course, the above process involves automated control, and the specific line arrangement and control device do not belong to the key discussion of the present invention, and will not be described herein. External dust winds enter the moisturizing fluid cavity 5 under differential pressure, and some dust particles will gradually condense with the fog droplets, and some dust particles will be adhered to the dust after moisturizing. The fluid plate 17, the sewage will be contained along the inhibition of dust supply plate 17 to the collecting groove 13, and the sewage can be emptied to the first discharge port of the intensive groove 13.
 The dust-filled power component 7 needs to use a mine explosion-proof fan with a coal moisture.
 The wetting chamber 14 is in communication with the growth rate reduction member 6, and the growth rate reduction member 6 includes a tapered inlet 18, a steady flow wind cylinder 19, a gradual exit 20, wherein the tapered inlet 18 and the gradual exit port 20 are The upper bottom diameter is 0.1 to 0.2m, the lower end diameter is 0.3 to 0.5m, the two rounds of 0.2 ~ 0.3m, and the two reverse placed, the diameter of the steady flow air cylinder 19 and the upper bottom phase of the tapered inlet 18 and the gradual exit port 20 Adapter, the steady flow air cylinder 19 can achieve a length adjustment of 0.3 to 1.0 m according to the sputum body.
 The tapered inlet 18 of the growth rate reduction member 6 is used to improve the dust-free wind speed, which produces a negative pressure suction effect at the tail flow to further enhance the negative pressure in the wetting passage chamber 5; growth decompression The steady flow wind cylindrical effect of the member 6 is used to eliminate the turbulence of dust-shaped stains, and the dust particles are avoided in the growth rate reduction member 6, so that the dust-containing wind is dust-saving. Dynamic member 7 is incident with the settlement purification mechanism 2 after boosting.
 The settling purification mechanism 2 includes a filter box 10, a inertial dehumidifier 11, a gradual expansion stream member 12, sequentially connected to the second telescopic negative pressure wind cylinder 8-3.
 Further, the above-mentioned filter box 10 is a long square having a length of 0.5 to 1.0m, width, from 0.8 to 1.0m, and a lower portion of a circular stain 21 having a diameter of 0.2 to 0.3m, and a bust inlet 21 pair. A clean wind exit 22 having a diameter of 0.2 to 0.3 m is set. The filter box 10 is contained in the dust collecting agent solution, which is used to efficiently settled dust particles in dust-containing stain. The height of the dust collecting liquid surface should be flooded with the stain inlet 21 but below the clean air outlet 22, the stain inlet 21 mounts liquid stop countervers 9. Only the dust-containing wind is allowed to enter the filter box 10 from the bust inlet 21, and the dust collecting agent solution in the filter box 10 can be avoided. The upper portion of the filter box 10 is provided with a reducing port 23, and the bottom is provided for a second rolling port 24 for regularizing the waste liquid in the filter box 10 and replaces the dust collecting agent solution.
 The inertial dehumidifier 11 includes a U-type dehumidifying chamber 25, a tubular cavity of 0.3 to 0.5 m, a diameter of 0.1 to 0.2 m, and a 90 ° corner is provided on both sides, and a blast port 26 is provided at the bottom of the cavity. After purification, the wet routing has been shocked by the wet cavity 25 bottom corner. The droplets are trained from the gas stream, along the abduction to the third row of stains 26, and the dry cleanliness is covered into the lane in fresh air. This ensures that the liquidity of the cover is sufficient, and the environment is clean.
 The expansion stream member 12 has gradually expanded, so that the dry clean rhythm is further reduced, which is conducive to the stabilization of the wind and can effectively avoid the impact of the routine.
 The dust concentration of the work is less than 50mg / m 3 The dust removal power member 7 and the inductive solenoid valve 16 will automatically stop closing the interval 3 to 5 s.
 Of course, the above description is not limited to the present invention, and the present invention is not limited to the above examples, and those skilled in the art will change, modification, addition or replacement in the spirit of the invention, should also belong to this The scope of the invention.
