Setting up fire prevention device and heat sink at present in the pit and occuping in the pit that the space is big for solving, the problem that the cost is high designs. It includes low temperature inert fluid storage tank, and low temperature inert fluid storage tank includes the casing, and there is the protective housing casing outside, and fill insulant material between protective housing and the casing is connected with into on the low temperature inert fluid storage tank, the drain pipe way, advances, the drain pipe establishes manometer, relief valve on saying, the other end and the pipeline that advance, the drain pipe are said link to each other, and a pipeline's the other end is connected with the import of wind -warm syndrome interchanger, and the export and the 2nd pipeline of wind -warm syndrome interchanger are continuous. The delivery pump is established between low temperature inert fluid storage tank and wind -warm syndrome interchanger, and the terminal of the import of pressure regulation and control ware and the 2nd pipeline links to each other, and the exit linkage of pressure regulation and control ware has the 3rd pipeline. The advantage is that to cool down fire prevention effectual.
Description
Technical field：
The utility model is related to underground high-temperature mine and fire extinguishing integrated apparatus, more particularly to a kind of to underground transportation
Tunnel, working face, return aircourse, development end and goaf are lowered the temperature, the device of fire extinguishing.
Background technology：
During pit mining, spontaneous fire problem and Problems On The Geotemperature are increasingly protruded.Fire and gas explosion accident
Happen occasionally, the life security and national resources to miner bring about great losses.But constantly to deep mining, underground heat must in colliery
So manifest serious；Or mine due to oxidation of coal produce a large amount of heat energy and high-power machine run discharge in itself heat it is larger etc. because
Element, causes getting working face area constant temperature to increase even beyond state-set standard, causes worker laboring environment severe, seriously
Influence is physically and mentally healthy.
Above two natural calamity endangers problem, is solved often by respective countermeasure approach, and fire extinguishing is arranged by fire extinguishing
Solution is applied, this respect measure is more；And for cooling, current majority is to being directly injected into cold air in mine by air conditioner refrigerating
Carry out the measure solution such as lower the temperature.This cool-down method power consumption is big, high cost and DeGrain.
Fire extinguishing device is set in underground in addition and heat sink takes underground space greatly, cost is high.
The content of the invention：
Technical problem to be solved in the utility model is to provide one kind and cryogenic inert liquid safe can be transported into well
The lower region for needing to lower the temperature with fire extinguishing, can simultaneously play the down-hole high-temperature mine of cooling and fire extinguishing function and prevent, go out
Fiery integrated apparatus.
What above-mentioned purpose was realized in：It includes cryogenic inert wet tank, described cryogenic inert wet tank bag
Housing is included, housing outside is provided with containment vessel, the space between containment vessel and housing is filled with insulation material, the storage of cryogenic inert liquid
Be connected with liquid inlet and outlet pipeline on tank, described liquid inlet and outlet pipeline is provided with pressure gauge, safety valve, liquid inlet and outlet pipeline it is another
End is connected with the first conveyance conduit, and the other end of the first conveyance conduit is connected with the import of wind-warm syndrome exchanger, wind-warm syndrome exchanger
Outlet be connected with the second conveyance conduit.
Delivery pump and pressure regulator can also be set up, described delivery pump is located at cryogenic inert wet tank and wind-warm syndrome is handed over
Between parallel operation, the end of liquid inlet and outlet pipeline is connected with the import of delivery pump, the head end of the first conveyance conduit and the outlet of delivery pump
It is connected, the import of described pressure regulator is connected with the end of the second conveyance conduit, the outlet of pressure regulator is connected with the
Three conveyance conduits.The outlet of the 3rd conveyance conduit enters goaf or is connected with the fire extinguishing conveyance conduit in colliery.
Described cryogenic inert liquid can be liquid nitrogen or liquid carbon dioxide.
The utility model has the advantages that：By the liquid conveying in cryogenic inert wet tank to underground correct position.Pass through
Delivery pump discharges into wind-warm syndrome exchanger cryogenic inert liquid；Cryogenic inert liquid is converted into gas in wind-warm syndrome exchanger
During discharge a large amount of colds, heat exchange is carried out with the hot-air in the middle of environment, so as to reach to the effect of environment temperature reduction.Will be low
After warm inert fluid injection oxidation and spontaneous combustion band, oxidation reaction heat build-up condition is not only broken up, prevented oxidation reaction, served resistance
Combustion is acted on.
By taking liquid nitrogen as an example, the liquid nitrogen in cryogenic inert wet tank is delivered to wind-warm syndrome exchanger and in wind by delivery pump
Nitrogen is gradually converted into warm exchanger, nitrogen is injected into the oxidation that oxidized zone suppresses coal.And turn the cold energy of gas process release i.e.
It is to the process of environment temperature reduction.
Its oxidation of coal problem and inerting oxidation and spontaneous combustion band internal oxidition for both having solved during coal mining in oxidized zone reacts
Required oxygen concentration and heat build-up heat up and trigger the condition of spontaneous fire；Solve again because cryogenic inert liquid turns to be released during gas
The problem that the cold put is lowered the temperature to underground coal mine local environment.The system simple structure, easy to operate, reducing temperature for preventing extinguishing effect
It is good, overall equipment safety reliability.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Specific embodiment：
The utility model is described further with reference to Fig. 1；
It includes cryogenic inert wet tank, and described cryogenic inert wet tank includes housing 1, and housing outside is provided with guarantor
