Abstract
The invention provides a temperature reduction and dehumidification device for a mine movable rescue capsule and aims to solve the technical problem that when an air conditioner is directly used in the rescue capsule, novel problems which cannot be solved are generated. The temperature reduction and dehumidification device has the key points that a plurality of liquid carbon dioxide steel cylinders are arranged in an equipment cabin; liquid carbon dioxide is used as a refrigerant; the liquid carbon dioxide steel cylinders, a high pressure gauge, a main valve, a throttling valve, a thermostatic expansion valve, an evaporator, a low pressure gauge, a reversing valve and a pneumatic fan are connected sequentially through pipelines; except for the liquid carbon dioxide steel cylinders, other components are arranged in a main cabin; and another inlet of the reversing valve is connected with an inherent compressed-air system of a mine. After a mine accident occurs, the temperature reduction and dehumidification device can work independently and the reliable temperature reduction and dehumidification device can be provided for the rescue capsule and has great significance on prolonging the lives of miners and prolonging the rescue time.
Description
Technical field
The present invention relates to a kind of cool-down dehumidification device, is the cool-down dehumidification device on the mining packaged type survival capsule specifically.
Background technology
Being provided with in underground mine and using mining packaged type survival capsule is a important measures in the mine emergency management and rescue.The packaged type survival capsule generally is made of successively transfer chamber, main cabin and equipment compartment, and transfer chamber is used for the external world and main cabin are isolated, and main cabin is the main space that wrecked personnel take refuge and survive, and is one sealed space.During mine disaster such as phenomenons such as blast, impact, fire, can produce hot environment in the well, the trapped personnel in survival capsule self metabolism meeting constantly produces heat and moisture.Therefore, heat and the steam accumulation problem that how to solve in confined space is the most difficult part in the survival capsule research.Generally, the packaged type survival capsule uses the intrinsic compressed-air system of mine to come cool-down dehumidification, is about to the intrinsic compressed-air system of mine and inserts in the packaged type survival capsule.But after the generation mine disaster, the intrinsic compressed-air system of mine can be destroyed sometimes, can't provide ventilation to survival capsule.This moment, the packaged type survival capsule needed a device that is similar to air-conditioning that the function of cool-down dehumidification is provided for main cabin.
The most electrification air-conditionings of external packaged type survival capsule are controlled temperature, air-conditioner host places survival capsule inside, and compressor must be external, this has produced compressor of air conditioner again must explosion-proof problem, and air-conditioning has individual maximum operating temperature, after mine disaster takes place, the mine environmental parameter complexity is difficult to guarantee that air-conditioning can operate as normal.
Summary of the invention
For solving the problems of the technologies described above, the objective of the invention is to provides a kind of cool-down dehumidification device that does not need power supply, do not need external compressor for the packaged type survival capsule.
The object of the present invention is achieved like this: place several liquid carbon dioxide steel cylinders at equipment compartment, 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 pipeline, each parts except that the liquid carbon dioxide steel cylinder are arranged in the main cabin, and another inlet of reversal valve connects the intrinsic compressed-air system of mine.When the mine compressed air system does not meet with destruction, drive blower fan by compressed-air system.When mine presses air feed system experience destruction not work, and native system started when temperature was greater than 30 ℃ in the survival capsule, and the cryogenic gaseous carbon dioxide after the throttling enters evaporimeter and carries out heat exchange, and 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 survival capsule, 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 survival capsule at last.When the mine compressed air system does not meet with destruction, drive blower fan by compressed-air system.
Compared with prior art, the invention has the beneficial effects as follows: it can work alone after mine disaster takes place, and for survival capsule provides reliable cool-down dehumidification device, this is to prolonging miner's life, and it is significant to prolong rescue time.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Accompanying drawing is a schematic diagram of the present invention.
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 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 enters choke valve through main valve, and the main function of choke valve is by the output of control refrigerant flow control refrigerating capacity.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 compressed air system does not meet with destruction, drive blower fan by compressed-air system.
