Abstract
The invention relates to a gas washing system and washing method for an underground shelter. The domestic traditional gas washing systems for underground shelters need electric drive, if mine disaster occurs, no power is provided under the general conditions, so that the gas washing systems for underground shelters lose action, and the rescue purpose can not be achieved, thereby bringing potential safety hazards for rescue works. The gas washing system for an underground shelter comprises a compressed air bottle (1), wherein the compressed air bottle is connected with a pressure reducing valve (2); the pressure reducing valve is connected with an air channel (4) through a pipeline (3); the air channel is connected with a pneumatic blower (5) through a pipeline; the pneumatic blower is provided with a silencer (6) and a regenerated air outlet; a filter screen (7) is arranged at the inlet of the pneumatic blower; and an adsorbing agent (8) is arranged above the filter screen. The invention is used for air purification and regeneration in the underground sheltering process.
Description
Technical field:
The present invention relates to a kind of down-hole refuge go up used for down-hole refuge gas scrubbing system and washing methods, be specifically related to a kind of for down-hole refuge gas scrubbing system and the method for using this system to wash.
Background technology:
Domestic existing down-hole refuge on for down-hole refuge gas scrubbing system all need driven by power, if when mine disaster occurs, generally all there is no electricity, like this down-hole refuge on for down-hole refuge gas scrubbing system just lost effect, do not reach the object of rescue; To rescue work, brought potential safety hazard.
Summary of the invention:
The object of this invention is to provide a kind of air filtering system, be applicable to down-hole refuge transfer chamber in, remove pernicious gas and the dust when the personnel of taking refuge enter transfer chamber, brought into, ensure its down-hole refuge life security.
Above-mentioned object realizes by following technical scheme:
For down-hole refuge gas scrubbing system, its composition comprises: compressed air bottle, described compressed air bottle connects reducing valve, described reducing valve connects air channel by pipeline, described air channel connects pneumatic fan by pipeline, on described pneumatic fan, with noise damper and regeneration air outlet, screen pack is equipped with in described pneumatic fan import, and adsorbent is equipped with in described screen pack top.
Described for down-hole refuge gas scrubbing system, described reducing valve comprises high pressure gauge and low-pressure meter.
For down-hole refuge a gas scrubbing process, the oxygen in compressed air bottle reduces pressure by pressure reducer, by regulating reducing valve gas after treatment to control the rotating speed of pneumatic fan; The air of wish processing enters in watertight aircase by adsorbent and screen pack, removes pernicious gas in mixing air and filters out after dust simultaneously, enters pneumatic fan, converges with oxygen, and the gas after dissolved oxygen rotates output with blower fan.
Beneficial effect:
1. the present invention drives gas flow by high pressure air drives pneumatic fan, by adsorbent and the screen pack of the pernicious gas for different collieries, removes pernicious gas and dust, without driven by power, safer stable.
2. the design indicates of the noise damper that the present invention adopts the design concept that people-oriented, avoid evoking the personnel's of taking refuge irritated mood, create the environment of a relative comfort; Noise while reducing air outflow, creates good environment to the personnel of taking refuge; Due to the combination of gases at high pressure outlet opening and noise damper, reduced system noise.
The present invention be applicable to down-hole refuge transfer chamber in, remove pernicious gas and the dust when the personnel of taking refuge enter transfer chamber, brought into, effectively ensured down-hole refuge personnel's oxygen supply and the besoin de respirer of clean air, ensure the safety of human life.
4. the present invention is with the pressure-air source that is used as power, and in the situation that there is no power supply, still the fresh air of supply normally carries out rescue work, reaches the object that guarantees rescue.
5. filtration fraction of the present invention is to be comprised of the filtration adsorpting formulation for different mine pernicious gases, activated carbon and special gas special filtering cavernous body, and filter effect is better, more thorough.
6. filtration system of the present invention has multifunctionality, not only can wash the toxic and harmful of transfer chamber, can also in main cabin, provide fresh in oxygen air.
Accompanying drawing explanation:
The structural representation that accompanying drawing 1 is this product.
The specific embodiment:
Embodiment 1:
Embodiment 1:
A kind of for down-hole refuge gas scrubbing system, its composition comprises: compressed air bottle 1, described compressed air bottle connects reducing valve 2, described reducing valve connects air channel 4 by pipeline 3, described air channel connects pneumatic fan 5 by pipeline, on described pneumatic fan, with noise damper 6 and regeneration air outlet, screen pack 7 is equipped with in described pneumatic fan import, and adsorbent 8 is equipped with in described screen pack top.
Described for down-hole refuge gas scrubbing system, described pneumatic fan 5 is with described noise damper 6, with described screen pack 7, be all contained in watertight aircase 9 with described adsorbent 8.
Embodiment 2:
According to described in embodiment 1 for down-hole refuge gas scrubbing system, described reducing valve comprises high pressure gauge 10 and low-pressure meter 11.
Embodiment 3:
Utilize the product of embodiment 1-2 carry out down-hole refuge the method for gas scrubbing, the oxygen in compressed air bottle reduces pressure by pressure reducer, by regulating reducing valve gas after treatment to control the rotating speed of pneumatic fan; The air of wish processing enters in watertight aircase by adsorbent and screen pack, removes pernicious gas in mixing air and filters out after dust simultaneously, enters pneumatic fan, converges with oxygen, and the gas after dissolved oxygen rotates output with blower fan.
When the personnel's mine disaster of taking refuge occurs, first people opens down-hole refuge institute door and enters transfer chamber, closes hatch door.Open transfer chamber gas scrubbing unit controls valve, carry out transfer chamber gas scrubbing 3～5 minutes, close transfer chamber gas scrubbing unit controls valve, when needs supply oxygen and fresh air, again start.
