Description
Technical field：
The present invention relates to down-hole high-temperature mine and fire extinguishing integrated apparatus, more particularly to a kind of to underground transportation tunnel, work
Make face, return aircourse, development end and goaf lowered the temperature, the device of fire extinguishing.
Background technology：
During pit mining, spontaneous fire problem and Problems On The Geotemperature are increasingly projected.Have when fire and gas explosion accident
Occur, bring about great losses to the life security and national resources of miner.But constantly to deep mining, underground heat necessarily shows in colliery
It is now serious；Or mine discharges the factors such as heat is larger because oxidation of coal produces a large amount of heat energy and high-power machine run itself, leads
Cause getting working face area constant temperature to increase even beyond state-set standard, cause worker laboring environment severe, have a strong impact on
It is physically and mentally healthy.
Above two natural calamity endangers problem, solves 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 be directly injected into cold air into 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.
In addition fire extinguishing device is set in down-hole and heat sink takes down-hole space greatly, cost is high.
The content of the invention：
The technical problem to be solved be to provide one kind can by cryogenic inert liquid safe be transported to down-hole need drop
The region of gentle fire extinguishing, can simultaneously play the down-hole high-temperature mine of cooling and fire extinguishing function and anti-, fire-extinguishing integrated
Device.
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.
It is an advantage of the invention that：By the liquid conveying in cryogenic inert wet tank to down-hole correct position.By conveying
Pump discharges cryogenic inert liquid into wind-warm syndrome exchanger；Cryogenic inert liquid is converted into the process of gas in wind-warm syndrome exchanger
It is middle to 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.Low temperature is lazy
Property liquid injection oxidation and spontaneous combustion band after, not only broken up oxidation reaction heat build-up condition, prevent oxidation reaction, serve fire-retardant work
With.
By taking liquid nitrogen as an example, the liquid nitrogen in cryogenic inert wet tank is delivered to into wind-warm syndrome exchanger and in wind by delivery pump
Nitrogen is gradually converted in 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.
It had both solved the oxidation of coal difficult problem during coal mining in oxidized zone and inerting oxidation and spontaneous combustion band internal oxidition reacts
Required oxygen concentration and heat build-up heats up and causes the condition of spontaneous fire；Solve again because cryogenic inert liquid turns to be released during gas
The difficult 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
Good, integral installation is for safe and reliable.
Description of the drawings：
Fig. 1 is the structural representation of the present invention.
Specific embodiment：
The present invention is described further with reference to Fig. 1；
