Abstract
The utility model provides a cooling and dehumidifying device of a refuge chamber for mines, which resolves the problem that using air conditioners directly in the refuge chamber can lead to new irresolvable problems. The cooling and dehumidifying device of the refuge chamber for mines is characterized in that a liquid state carbon dioxide steel cylinder, a high pressure gauge, a master valve, a throttling valve, a thermostatic expansion valve, an evaporator, a low pressure gauge, a reversing valve and a pneumatic fan are connected in sequence through pipelines. The liquid state carbon dioxide steel cylinder is arranged in a transition region, and the other parts are arranged in a living area. After a mining disaster happens, the cooling and dehumidifying device of the refuge chamber for mines can work independently, thereby providing the refuge chamber with a reliable cooling and dehumidifying device and further facilitating the guarantee of life safety of miners and the prolonging of rescue time.
Description
Technical field
The utility model relates to a kind of cool-down dehumidification device, is the cool-down dehumidification device of mine refuge chamber specifically.
Background technology
Setting and use emergency-sheltering chamber are important measures in the mine emergency management and rescue in underground mine.
During mine disaster as blast, accidents such as impact, fire, can cause the abominable hot environment in the mine.In refuge chamber, trapped personnel self metabolism meeting constantly produces heat and moisture.Therefore, how solving heat in the confined space and steam accumulation problem, promptly to solve the cool-down dehumidification problem be the most difficult part in the refuge chamber research.
Generally, refuge chamber uses the intrinsic ventilation system of mine to come cool-down dehumidification, and ventilation system intrinsic under the mine is inserted in the refuge chamber.But after the generation mine disaster, intrinsic ventilation system can be destroyed in the mine sometimes, can't provide ventilation to refuge chamber.Need this moment a device that is similar to air-conditioning that the function of cool-down dehumidification is provided for refuge chamber.
The most electrification air-conditionings of external refuge chamber are controlled temperature, and air-conditioner host can place refuge chamber inside, and compressor must be external, and therefore, the explosion-proof problem of the external compressor of air conditioner of refuge chamber is difficult for solving.In addition, air-conditioning needs enough electric power and keeps operation of air conditioner, and external power very likely interrupts during mine disaster.Therefore, directly use air-conditioning can produce some new insurmountable problems at refuge chamber.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of cool-down dehumidification device of mine refuge chamber.
The purpose of this utility model is achieved in that refuge chamber is made of transition region, living area, place several liquid carbon dioxide steel cylinders in transition region, liquid carbon dioxide is as cold-producing medium, liquid carbon dioxide steel cylinder, high pressure gauge, main valve, choke valve, heating power expansion valve, evaporimeter, low-pressure meter, reversal valve and pneumatic blower fan are connected successively by the high-pressure pneumatic pipeline, each parts except that the liquid carbon dioxide steel cylinder are called main frame and are arranged in the living area, and another inlet of reversal valve connects the intrinsic ventilation system of mine.When taking refuge cave when mine air feed system experience destruction can not be worked, and native system started when temperature was greater than 30 ℃ in the chamber, cryogenic gaseous carbon dioxide after the throttling enters evaporimeter and carries out heat exchange, the gas that comes out from evaporimeter enters pneumatic blower fan, the rotation of driving shaft flow fan is flowed indoor gas.Because the dewpoint temperature of evaporator temperature air in the chamber, airborne moisture will condense in evaporator surface, thereby realize the function of cool-down dehumidification.Air behind the cool-down dehumidification reenters the living area.Tail gas after the refrigeration is sent to outside the chamber at last.When the mine air feed system outside the refuge chamber does not meet with destruction, drive blower fan by ventilation system.
Compared with prior art, the beneficial effects of the utility model are: it can work alone after mine disaster takes place, and for refuge chamber provides reliable cool-down dehumidification device, this is to ensureing miner's life security, and it is significant to prolong rescue time.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is a schematic diagram of the present utility model.
The specific embodiment
Liquid carbon dioxide steel cylinder 1, high pressure gauge 12, main valve 3, choke valve 4, heating power expansion valve 5, evaporimeter 6, low-pressure meter 7, reversal valve 8 and pneumatic blower fan 9 are connected successively by pipeline 11, the liquid carbon dioxide steel cylinder is arranged on transition region 13, remaining part is called main frame and is arranged in the living area 2, and another inlet of reversal valve connects the intrinsic ventilation system of mine 10.Open choke valve during system works, high pressure gauge is a normally open, and the high pressure low temperature carbon dioxide is through choke valve, and the main function of choke valve is to control refrigerating capacity output by the control refrigerant flow.The carbon dioxide coolant that comes out from choke valve enters evaporimeter after by the expansion valve throttling; Heating power expansion valve is the open and close that relies on the outer temperature-sensitive bag control expansion valve of transition chamber.By the cold-producing medium after the expansion valve throttling is cryogen, and this cryogenic gas carries out interchange of heat by the air in the evaporimeter and the external world.The carbon dioxide that evaporimeter comes out drives pneumatic blower fan and carries out air blast, realizes the cross-ventilation of whole system.Last carbon dioxide is discharged chamber outer 14.
When the mine air feed system outside the refuge chamber does not meet with destruction, drive blower fan by ventilation system.
If chamber is bigger, in the living area two main frames can be set, two main frame parallel connections.
Claims (2)
1. the cool-down dehumidification device of a mine refuge chamber, it is characterized in that: refuge chamber is made of transition region, living area, liquid carbon dioxide steel cylinder, high pressure gauge, main valve, choke valve, heating power expansion valve, evaporimeter, low-pressure meter, reversal valve and pneumatic blower fan are connected successively by pipeline, the liquid carbon dioxide steel cylinder is arranged on transition region, remaining part is called main frame and is arranged in the living area, and another inlet of reversal valve connects the intrinsic compressed-air system of mine.
2. according to the cool-down dehumidification device of the described mine refuge chamber of claim 1, it is characterized in that: two main frames are set, two main frame parallel connections in the living area.
