Detailed description of the invention
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of mining drill orifice wet scrubber, the dust cover adapter 1-3 on dust arrester 1 top is by Flange joint flexible pipe adapter 2-1, flexible pipe adapter 2-1 connecting hose 2(flexible pipe can be mild steel fiber tube), flexible pipe 2 connects jet dish 6, jet dish 6 is a funneling tubulose (namely thickness is uneven), centre is provided with aqueous vapor shower nozzle 5(around it by dust and methane gas), aqueous vapor shower nozzle 5 being connected to respectively this place of water interface 3 gentle interface 4(Fig. 1 led to outside jet dish 6 is sectional drawing), can be gentle to water flowing in aqueous vapor shower nozzle 5 by the gentle interface of water interface 34, jet dish 6 is by rear thin pipe thick before Flange joint spray chamber 71(), spray chamber 71 connects jet pipe 7, and jet pipe 7 afterbody is provided with shunting grid 8.Outfall 72 backward and downward sewage draining exit 73 is provided with after shunting grid 8.Shunting grid 8 are the helical blade of some separation, and it can alleviate the speed of water smoke effectively, makes water smoke be unlikely to high speed straight to ejection, thus the sewage of band coal dust is discharged from sewage draining exit 73; Other steam fog is then discharged backward by outfall 72.
The structure of dust arrester 1 is: dust cover 1-2 is two semicircular structure (being generally lower half circle), can fasten rear fixing; Dust cover 1-2 front portion arranges groove card 1-6, the cylinder edge at the sleeve 1-1 rear portion that can be fastened; Sleeve 1-1 is placed in rib hole; Be provided with ring-type hairbrush 1-4 in the middle part of dust cover 1-2, rear portion is provided with ring-type hairbrush 1-4, the fixing outer ring of two ring-type hairbrush 1-4 is fixed on by screw on the inwall of dust cover 1-2; Ring-type hairbrush 1-4 also can be fixed on inwall by connecting ring, and namely the fixing outer ring of ring-type hairbrush 1-4 is screwed on connecting ring, and connecting ring is fixed on dust cover 1-2 inwall; Drilling rod 20 passes from the endoporus of ring-type hairbrush 1-4; Dust cover 1-2 top is dust cover adapter 1-3, by Flange joint flexible pipe adapter 2-1, flexible pipe adapter 2-1 connecting hose 2; Dust cover 1-2 bottom, for leading dirt funnel 1-5, by leading dirt funnel 1-5, can be taken drilling rod 20 out of larger grit and lead away.
During use, sleeve 1-1 is placed in and need holes in the rib hole of rib, holes, and particle is taken in boring out of and dust is brushed down through hairbrush, and particle falls into leads dirt funnel 1-5, and lighter dust and methane gas are inhaled into flexible pipe 2 under suction; When dust is by jet dish 6, gentle owing to being connected with water in aqueous vapor shower nozzle 5, under the effect of Wen Qiuli pipe principle, be atomized (form negative pressure simultaneously, produce suction), form dust mist, when dust mist is by shunting grid 8, owing to shunting the barrier effect of canopy 8, dust mist forms the globule, finally discharges from outfall 72.
For reducing noise, there is noise damper 9 in the outer setting of jet pipe 7.
Structure of the present invention is simple, and with low cost, good dedusting effect, is easy to carry and installs.Effectively improve operating environment.
What finally illustrate is; above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted; other amendments that those of ordinary skill in the art make technical scheme of the present invention or equivalently to replace; only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of protection scope of the present invention.
