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 are some cleaners to enter using blast and hydraulic pressure collective effect using the wind and water smoke of certain pressure
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 be the negative pressure region the drawbacks of, that is to say, that：On the one hand, processing dust pipeline in if
Air outlet tube mouth is at the rear of aqueduct shower nozzle, and atomizing effect difference is so that still there is dust in the exit of cleaner if hydraulic pressure is too small
Wave, the wind that the water smoke that the pipeline inner conduit shower nozzle of processing dust is sprayed if hydraulic pressure is excessive is blown out to airduct has certain
Resistance and cause negative pressure in cleaning shaft reduce the dust for causing drilling neighbouring take out it is motionless；On the other hand, in processing dust
Negative pressure region of the water smoke that aqueduct shower nozzle sprays if front of the air outlet tube mouth in aqueduct shower nozzle in pipeline at airduct mouth rear
It is interior so that water smoke and dust condense and easily block aqueduct shower nozzle and cleaning shaft.
