Abstract
The utility model discloses a wet dust removal system for a coal-mine gas pumping-exhaust drill hole, relating to the dust removal technology for the coal-mine gas pumping-exhaust drill hole. The system is mainly applied to the dust removal at the orifice of the dry-method drill hole of underground gas pumping-exhaust of a coal mine, and particularly refers to a wet dust collector system for the dust removal at the orifice of the coal-mine gas pumping-exhaust drill hole. The system comprises a dust control box, wherein the front side of the dust control box is connected with a dust collection pipe; a dust collection bag is connected below the dust control box, and a hose is connected above the dust control box; the other end of the hose is connected with an injection pipe; a compressed gas distribution chamber and a water inlet pipe spray head are arranged in the injection pipe; the other end of the injection pipe is connected with a mixing pipe; the upper end in the dust control box is connected with a filter net. Since the filter net is welded at the upper end in the dust control box, the system disclosed by the utility model has the advantages that (1) large coal dust is blocked and falls to the ground from the dust collection bag; (2) the smoothness of the pipeline and dust collector is guaranteed; (3) the water gas resource is utilized more effectively to remove dust, and the dust removal effect is enhanced.
Description
Technical field
The utility model relates to Patent classificating number E21B 21/00, E21B 21/16 technical field, coal mine gas pump drainage boring dedusting technology, is mainly used in the dedusting of coal mine gas pump drainage dry method drilling orifice, refers in particular to a kind of coal mine gas pump drainage drilling orifice dedusting wet scrubber system.
Background technology
Gas in coal seam threatens the safety of coal mining, one important step before coal mining is need to be in recovery process, the methane gas of constantly holing in pump drainage coal seam at coal mine down-hole tunnel wall, when being holed, weak seam dry method adopts compressing-deslagging technique, the dirt slag that boring procedure produces gap along drilling rod and hole wall under Compressed Gas effect sprays, cause the dust pollution of tunnel work plane serious, dangerous with harm operating personnel healthy; Meanwhile, in the dusty gas of boring ejection, with high concentration gas, have the danger that produces explosion accident, safety regulations in coal mine provides against to be used motor for power or can produce friction spark, have the blower fan of rotary blade to aspirate dusty gas dedusting.
Existing coal mine gas pump drainage boring wet dedusting system mainly comprises control dirt box, the front side of control dirt box connects dust leg, the top connecting hose of control dirt box, and the below of control dirt box connects dust collecting sleeve, the other end of flexible pipe connects induction tunnel, and the other end of induction tunnel connects mixing tube.The shortcoming of this structure mainly contains following 2 points: 1, bulky grain ickings can be sucked by deduster, increases dedusting difficulty, reduces dust removing effects, waste aqueous vapor resource; 2, use for a long time, bulky grain ickings can stop up deduster to lose efficacy.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of coal mine gas pump drainage boring wet dedusting system of good dedusting effect is provided.
The purpose of this utility model is achieved in that coal mine gas pump drainage boring wet dedusting system, comprise control dirt box, the front side of control dirt box connects dust leg, the below of control dirt box connects dust collecting sleeve, the top connecting hose of control dirt box, the other end of flexible pipe connects induction tunnel, and Compressed Gas distributor chamber and water inlet pipe shower nozzle are set in induction tunnel, the other end of induction tunnel connects mixing tube, and the upper end in described control dirt box connects screen pack.
The utility model, by the upper end welding screen pack in control dirt box, has the following advantages: 1, block bulky grain ickings, it is fallen earthward from dust collecting sleeve; 2, guarantee pipeline, deduster is unimpeded; 3, more effectively utilize aqueous vapor resource that dust is removed, strengthen dust removing effects.
Mixing tube of the present utility model is Venturi tube.
Mixing tube of the present utility model is straight tube.
Accompanying drawing explanation
Fig. 1 is the first structural representation of the present utility model.
Fig. 2 is the second structural representation of the present utility model.
Fig. 3 be the utility model use occasion with reference to figure.
In figure, 1 dust leg, 2 control dirt boxes, 3 dust collecting sleeves, 4 too fast acting flanges, 5 flexible pipes, 6 induction tunnels, 7 Venturi tubes, 8 straight tubes, 10 Compressed Gas distributor chambers, 11 water inlet pipe shower nozzles, 12 screen packs, 13 drilling rods.
The specific embodiment
As shown in Figure 1, for coal mine gas pump drainage boring wet dedusting system, comprise control dirt box 2, the screen pack 12 of the upper end welding lateral arrangement in control dirt box 2, the front side of control dirt box 2 connects dust leg 1, and the below of control dirt box 2 connects dust collecting sleeve 3, the top of control dirt box 2 connects coil component spring skeleton flexible pipe 5 by fast acting flange 4, the other end of flexible pipe 5 connects induction tunnel 6, interior Compressed Gas distributor chamber 10 and the water inlet pipe shower nozzle 11 of arranging of induction tunnel 6, and the other end of induction tunnel 6 connects Venturi tube 7.
As shown in Figure 2, the other end of induction tunnel 6 connects straight tube 8.
As shown in Figure 3, compressed air enters bit location by hollow drill 13, carries ickings secretly, and ejects from gap between drilling rod 13 and dust leg 1, and the dust-contained airflow of formation enters control dirt box 2 inner chambers; When compressed air is connected with the induction tunnel 6 of deduster, in pipeline of dust collector combination, form negative pressure, the floating dust of small particle diameter is pumped; Oarse-grained ickings is filtered net 12 and blocks, and from dust collecting sleeve 3, discharges, and falls into ground, and when high-pressure water hose is connected with deduster induction tunnel 6, the injection eddy flow complex dust collector of calming the anger starts dedusting work, be sucked and small size particle in deduster, remove.
