Description
Technical field
The present invention relates to a kind of drilling dust-removing apparatus, more particularly to a kind of coal mine drilling geomantic omen jet extraction dedusting dress
Put.
Background technology
Coal mine operation bad environments, gas and dust are two big dangerous matter sources in mine.Gas Outburst can destroy underground
Ventilating system causes underground wind current control and causes personnel to suffocate, and gas is met fire and can trigger explosion accident.Dust is strong to human body
Health harm is big, and the lighter then causes respiratory inflammation, and severe one then causes the pneumoconiosis, dust to cause skin disease and can stimulate eye mask；
And dust explosion is one of big disaster in colliery five；In addition dust concentration is high can reduce visibility, not only influence efficiency, also
Be easily caused maloperation, erroneous judgement and trigger security incident；Mechanical wear under the easy pick-up well of dust and greatly shorten precision instrument
Service life.Therefore in coal bed drilling, the dust and gas of generation have greatly to the production of miner, equipment and downhole safety
Harm.
Administered for coal mine gas, concordant drilling is carried out particularly in coal seam and is required to using pressure wind deslagging technique
And produce the process problem of a large amount of dust, dust to annoying underground work personnel always when coal mine down-hole drilling is constructed.To the greatest extent
Pipe people also develop some cleaners to process dust, but the effect of cleaning is very undesirable, is mainly manifested in：1st, it is existing
Cleaner volume is big, takes the limited space of underworkings, both unfavorable ventilation or the transport of influence pedestrian and material；2nd, dedusting
The environment that the big equipment of water consumption is easily caused in tunnel is poor, and then dedusting is not to the utmost for the small equipment of water for dust removal amount；3rd, itself does not possess
Dust suction act on and exist both water wasting can not fully erased dust.
Although also there is some cleaners to enter using the wind and water smoke of certain pressure using blast and hydraulic pressure collective effect
Row nebulization dust, but due in this kind of cleaner the mouth of pipe of airduct separated with the shower nozzle of water pipe, this certainly exists water
Press through that small, hydraulic pressure is excessive or water smoke is the drawbacks of negative pressure region, that is to say, that：On the one hand, treatment dust pipeline in if
At the rear of aqueduct shower nozzle, atomizing effect difference is so that still there is dust in the exit of cleaner to air outlet tube mouth if hydraulic pressure is too small
Wave, the wind that the water smoke that the pipeline inner conduit shower nozzle for the treatment of dust is sprayed if hydraulic pressure is excessive is blown out to airduct has certain
Resistance and cause negative pressure in cleaning shaft to reduce the dust near causing to drill and take out motionless；On the other hand, in treatment dust
Negative pressure region of the water smoke that aqueduct shower nozzle sprays if front in pipeline if air outlet tube mouth in aqueduct shower nozzle at airduct mouthful rear
It is interior so that water smoke and dust condense and easily block aqueduct shower nozzle and cleaning shaft.
