Abstract
The utility model relates to a liquid carbon dioxide cooling system for an underground coal mine escape capsule and a refuge chamber, which is designed for mainly solving the problem that no energy system is used for cooling the escape capsule and the refuge chamber after a power supply is cut off in the event of encountering a danger in the current coal mining. The system comprises a plurality of liquid carbon dioxide steel cylinders. Liquid outlets of the liquid carbon dioxide steel cylinders are connected with the inlet of a vaporizer through a pipeline. A first stop valve is arranged on the pipeline. The outlet of the vaporizer is connected with the inlet of a pneumatic motor fan through a pipeline. A pressure-adjusting valve is arranged on the pipeline. The outlet of the pneumatic motor fan is leaded to outside through a pipeline. The system further comprises a compression air storage tank. The outlet of the compression air storage tank is connected with the pipeline between the vaporizer and the pressure-adjusting valve through a pipeline. A second stop valve is arranged on the pipeline between the joint and the vaporizer. The system disclosed by the utility model has the advantage of also capable of cooling the escape capsule and the refuge chamber in the event of not having a power supply.
Description
Technical field:
The utility model relates to the liquid carbon dioxide cooling system that a kind of colliery down-hole survival capsule, refuge chamber are used.
Background technology:
In coal mining; The explosion accident of catching fire that is caused by methane gas or dust happens occasionally; When danger occurs, need arrive in survival capsule or the refuge chamber the miner of underground work and to take refuge, but behind dump; Owing to do not have and source energy system to be lowered the temperature by survival capsule, refuge chamber, make the miner's that takes refuge life security can not get ensureing.
Summary of the invention:
The utility model technical problem to be solved provides a kind of when mine disaster takes place, and colliery down-hole survival capsule and the refuge chamber that behind dump, still lower the temperature for down-hole survival capsule, refuge chamber are used the liquid carbon dioxide cooling system.
Above-mentioned purpose is achieved in that it comprises several liquid carbon dioxide steel cylinders; The liquid outlet of liquid carbon dioxide steel cylinder has pipeline to be connected with the inlet of vaporizer; First stop valve is arranged on this pipeline; The outlet of vaporizer has pipeline to link to each other with the inlet of air motor fan, on this pipeline pressure regulator valve is housed, and it is outdoor that the outlet of air motor fan has pipeline to lead to.
When the carbon dioxide gas leakage needs the stop valve on the closing carbon dioxide gas pipeline; In order to continue power to be provided to the air motor fan; Can set up compressed air reservoir; The outlet of compressed air reservoir has pipeline to be connected with pipeline between vaporizer and the pressure regulator valve, and on the pipeline between this junction and the vaporizer, establishes second stop valve.
Operating principle and advantage: open first stop valve between liquid carbon dioxide steel cylinder and the vaporizer during work; Liquid CO 2 in the liquid carbon dioxide steel cylinder gets into the vaporizer heat absorption of gasifying through liquid outlet; For survival capsule, refuge chamber are lowered the temperature; Gaseous carbon dioxide after the gasification reduces pressure in pipeline gets into pressure regulator valve; Post-decompression gaseous carbon dioxide gets into air motor fan inner chamber and drives the rotation of air motor fan, and the air that the fan rotation can be quickened in survival capsule, the refuge chamber flows, thereby reaches the purpose of cooling.Owing to be provided with compressed air reservoir, when carbon dioxide leakage, first stop valve on the closing carbon dioxide gas pipeline and second stop valve are opened the compressed air reservoir valve and power are provided for air motor fan air feed, make fan continue rotation in addition.Advantage is that cooling rate is fast, and is easy and simple to handle; Not having also to give survival capsule, refuge chamber cooling under the situation of power supply, can play very big effect to the safe life-saving protection of down-hole survival capsule, refuge chamber, also try to gain time precious to one for the coalmine rescue rescue.
Description of drawings:
Accompanying drawing is the structural representation of the utility model.
The specific embodiment:
With reference to accompanying drawing; It comprises several liquid carbon dioxide steel cylinders 1; The liquid outlet of liquid carbon dioxide steel cylinder has pipeline to be connected with the inlet of vaporizer 2 (buying from market), and first stop valve 7 is arranged on this pipeline, and the outlet of vaporizer 2 has pipeline to link to each other with the inlet of air motor fan 5; Pressure regulator valve 3 is housed on this pipeline, and it is outdoor that the outlet of air motor fan 5 has pipeline to lead to.
Also can set up compressed air reservoir 6, the outlet of compressed air reservoir has pipeline to be connected with pipeline between vaporizer 2 and the pressure regulator valve 3, and on the pipeline between this junction and the vaporizer 2, establishes second stop valve 4.
