Abstract
A cooling, fireproof and fire-extinguishing system by using liquid carbon dioxide relates to an air inlet roadway applied under a coal mine shaft, is used for cooling, preventing fire and extinguishing the fire in an oxidation and spontaneous combustion zone and an extraction working face area of a gob and is designed for solving the problems that power consumption is large, cost is high and the like when cooling is performed in the oxidation and spontaneous combustion zone and the extraction working face area of the gob. The cooling, fireproof and fire-extinguishing system comprises a liquid carbon dioxide storage tank arranged on a cart and a cold-accumulation cooling vaporizer. The cold-accumulation cooling vaporizer comprises a casing, a heat exchange tube is arranged in the casing, a cooling fin is fixed on the casing, and a water inlet and an overflow opening are further arranged on the casing. A liquid outlet of the liquid carbon dioxide storage tank is connected with a heat exchange tube inlet in the casing of the cold-accumulation cooling vaporizer through a pipeline, and a heat exchange tube outlet in the casing of the cold-accumulation cooling vaporizer is connected with a pipeline leading to the oxidation and spontaneous combustion zone and the extraction working face area of the gob. The cooling, fireproof and fire-extinguishing system by using the liquid carbon dioxide ahs the advantages of having low cooling, fireproof and fire-extinguishing costs and good effect.
Description
Technical field:
The utility model relates to a kind of intake under the coal mine that is applied in, the system that goaf oxidation and spontaneous combustion band and getting working face district are lowered the temperature, prevent fires, put out a fire.
Background technology:
In coal mining, to deep mining, the problem that spontaneous combustion ignition and ground temperature are high is more and more outstanding along with constantly.Combine the discharge technique development owing to combine to adopt, the goaf is left over the coal problem and can not get effective control, because the flow velocity degree that leaks out in the oxidation and spontaneous combustion band is very slow; Cause the heat that in oxidation reaction process, produces in time to distribute; Accumulate heat energy oxidation reaction is played heat effect, impel oxidation reaction further to accelerate, move in circles according to this; Oxidation reaction is constantly quickened, happened occasionally so leave over the involuntary ignition accident that the coal autoxidation causes.Be that underground goaf causes that spontaneous combustion causes CO to increase or gas explosion because local temperature is too high, be easy to bring about great losses to miner's life security and national resources.In addition; Because the colliery is constantly to deep mining; Underground heat must manifest seriously, and mine causes getting working face district temperature to continue to increase even exceed state-set standard because oxidation of coal produces factors such as a large amount of heats and the release heat of high-power machine run own are bigger; Cause the worker laboring environment abominable, have a strong impact on physical and mental health.
For addressing the above problem, majority is to solve through the refrigeration measure at present, promptly adopts air conditioner refrigerating in mine, directly to inject the cold air cooling, and the shortcoming of this cool-down method is that power consumption is big, and cost is high, and poor effect.
Summary of the invention:
The utility model technical problem to be solved provides a kind of cooling, fire prevention and low, effective liquid carbon dioxide cooling, fire prevention, the fire extinguishing system of fire extinguishing cost.
Above-mentioned purpose is achieved in that it comprises the liquid carbon dioxide storage tank; The liquid carbon dioxide storage tank places on the dolly, it is characterized in that also comprising the cold accumulation cooling-down vaporizer, and the cold accumulation cooling-down vaporizer comprises housing; Heat exchanger tube is housed in the housing; Be fixed with fin on the housing, also have water inlet and overfall on the housing, water or anti-icing fluid are housed in the housing; The liquid outlet of liquid carbon dioxide storage tank has the heat exchanger tube inlet in pipeline and the cold accumulation cooling-down vaporizer shell to link to each other, and the heat exchanger tube in the cold accumulation cooling-down vaporizer shell exports and links to each other with the pipeline that leads to goaf oxidation and spontaneous combustion band and getting working face district.
The utility model has the advantages that: with the liquid carbon dioxide storage tank with after the cold accumulation cooling-down vaporizer is connected; Liquid carbon dioxide in the liquid carbon dioxide storage tank is released in the cold accumulation cooling-down vaporizer; Liquid carbon dioxide discharges a large amount of cold energy in the internal conversion of cold accumulation cooling-down vaporizer becomes the process of gas; Carry out interchange of heat with the hot air in oxidation and spontaneous combustion band in goaf in the coal mine and getting working face district; Realize cooling; And will change into carbon dioxide behind the gas and be transported to the coal seam that inerting oxidation in the oxidation and spontaneous combustion band of goaf is ongoing or treat oxidation, lower the temperature and the fire-retardant purpose of inerting with the getting working face district thereby be reached in the coal mine goaf oxidation and spontaneous combustion band.And native system cooling, fire prevention and fire extinguishing cost are low, effective, simple in structure, easy to operate, and whole equipment is safe and reliable.
Description of drawings:
Accompanying drawing is the structural representation of the utility model.
The specific embodiment:
With reference to accompanying drawing, it comprises liquid carbon dioxide storage tank 1, and liquid carbon dioxide storage tank 1 places on the dolly 2; Also comprise the cold accumulation cooling-down vaporizer; The cold accumulation cooling-down vaporizer comprises housing 4, and heat exchanger tube 5 is housed in the housing, is fixed with fin 3 on the housing; Also have water inlet 7 and overfall 6 on the housing; Water or anti-icing fluid are housed in the housing, and the liquid outlet of liquid carbon dioxide storage tank 1 has pipeline to link to each other with cold accumulation cooling-down vaporizer shell 4 interior heat exchanger tube inlets, and the heat exchanger tube outlet in the cold accumulation cooling-down vaporizer shell links to each other with the pipeline that leads to goaf oxidation and spontaneous combustion band and getting working face district.
