Description
Technical field
The present invention relates to a kind of mine air refrigerating devie, cool-down dehumidification method and the device of especially a kind of mine danger-avoiding chamber, survival capsule; Belong to the special-purpose Refrigeration Technique apparatus field in mine.
Background technology
Mine danger-avoiding chamber and survival capsule are a kind of act of rescue place or equipment that is placed in the mine that carries out digging operation.When the major accidents such as burst blast, fire under the mine, if in time gug escape of underground work personnel is perhaps selected to enter to wait for rescue in mine danger-avoiding chamber and the survival capsule, will cause great life disaster nearby.The basic existence equipment such as a certain amount of food, oxygen supply that generally all stores in mine danger-avoiding chamber or the survival capsule is for the hedging librarian use.After a large amount of personnel entered, owing to chamber and survival capsule are invaded for isolated outside toxic and harmful and adopted totally-enclosed design, the heat that people's survival activity produces was added outside heat meeting that gas explosion and combustion produces so that internal temperature raises gradually.Thus, not only cause in the cabin and indoor temperature raises, simultaneously also can because of internal-external temperature difference and the indoor occupant physiological activity causes in the cabin or indoor humidity also increases; This abominable narrow and small living environment can have a strong impact on the personnel's of taking refuge the state of mind.Therefore, need timely gas cooling to inside badly.
Chinese patent CN201020689015.0 discloses a kind of anti-explosion air conditioning device for coalmine rescue capsule, by common aircondition is carried out explosion-proof consolidation process, sustainable gas in the survival capsule is carried out adjustment, because this aircondition is electric fixtures, in abominable Minepit environment, if device fails or have the hidden danger of initiation fire accident because of personnel's maloperation.Simultaneously, this equipment in use need consume a large amount of electric power, after the down-hole has an accident, the risk that exists supply of electric power to interrupt, if the storage battery power supply in the use survival capsule, because rescue time is indefinite, the electric power that long-time refrigeration can consume valuable, even affect the normal use of other existence equipment.The space is more limited in the narrow field under the mine, refuge chamber and survival capsule, settles a large amount of batteries obviously infeasible, does not also meet the safety requirements of mine production environment.
For avoiding the problems referred to above, Chinese patent CN200920288259.5 discloses a kind of liquid carbon dioxide that adopts as the ejector refrigeration system of cold-producing medium, this is a kind of comparatively advanced passive refrigeration mode, solved the power shortages problem of interrupting alive that electric chiller plant faces, but the pressure gas cylinder as the storing liquid carbon dioxide, itself also there is certain potential safety hazard in this metal high voltage container, need make regular check on and change, because environment is abominable under the mine, also easy because collide with injury in the transportation assembling process, more can cause gas concentration lwevel increase in the environment just in case occur to leak, so that the living environment of shelter is more abominable.
