Abstract
The utility model discloses a kind of gasification furnace liquid carbon dioxide to go out fast furnace system, this furnace system that goes out is furnished with liquid carbon dioxide storage facilities at grass, between grass and underground gasification furnace, be provided with conveyance conduit, be connected with valve by connecting pipe between storage facilities with conveyance conduit; The storage facilities of above-mentioned storing liquid carbon dioxide is liquefied carbon dioxide tank vehicle, low temperature liquid carbon dioxide holding tank or mining mobile liquid carbon dioxide fire extinguishing equipment.The utility model utilizes carbon dioxide to coal excellent adsorption, and inerting effect is good, and cooling is fast, can lower the temperature and inerting fast and effectively, effectively put out fast by coal seam gasification stove coal body, solves gasification furnace and to go out the slow-footed difficult problem of stove.
Description
Technical field
The utility model belongs to the furnace system that goes out of underground coal mine gasification stove.
Background technology
In recent years, a kind of gasifying process is not only in underground coal gasification(UCG) (Underground Coal Gasification), and is a kind of coal-mining method; Underground gasification is exactly the burning carrying out the coal being in underground to have control, by producing the process of fuel gas to the heat effect of coal and chemical action.Both at home and abroad for gasification furnace roadway layout and some stove technique study more, but few for stove research of how going out.
The go out method of stove of current employing mainly contains: disconnected oxygen go out stove, water filling go out stove, fill nitrogen go out stove, slip casting of stove, logical steam of going out and to go out stove and the used in combination stove method of comprehensively going out of above method.
Fill nitrogen to go out stove method, can inerting gasification zone but be difficult to take away heat.Water filling stove method of going out makes furnace heat constantly convert steam to, thus reduces furnace temperature and displace oxygen, but easily produces the danger such as water coal vapour blast, is difficult to control freely burning fire.Slip casting go out stove cooling scope little, be difficult to control and leak out.Comprehensively to go out stove method, first adopt steam go out stove stop working, then air cooling-down is carried out with atomized water spray, finally adopt slip casting method shutoff gasification furnace all enter outlet passageway, make underground gasification furnace and atmospheric isolation, faster than single stove method of going out, but in-furnace temperature can not be realized reduce fast, reach stove object of going out fast.
Liquid carbon dioxide has inerting, cooling and datonation-inhibition function, can be used for fire extinguishing, but the precedent of the stove that also goes out not used for gasification furnace at present.
Summary of the invention
The purpose of this utility model is to provide a kind of liquid carbon dioxide that utilizes and goes out fast to mine underground gasification furnace the system of stove, and effective realization is gone out the object of stove fast.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of gasification furnace liquid carbon dioxide goes out furnace system fast, it is characterized in that, this furnace system that goes out is furnished with liquid carbon dioxide storage facilities at grass, between grass and underground gasification furnace, be provided with conveyance conduit, be connected with valve by connecting pipe between storage facilities with conveyance conduit.
The storage facilities of described storing liquid carbon dioxide is liquefied carbon dioxide tank vehicle, low temperature liquid carbon dioxide holding tank or mining mobile liquid carbon dioxide fire extinguishing equipment.
Described conveyance conduit is the former gasification pipe of gasification furnace or the boring of newly boring from ground.
In order to ensure liquid carbon dioxide burst size, connecting pipe is provided with flow meter and pressure meter.
Good effect of the present utility model is:
1, go out stove time, in gasification furnace, high-temperature gas and-5 DEG C of liquid carbon dioxide gas carry out interchange of heat, give off high-temperature high concentration CO gas by rough gas gas vent, thus reduce goaf temperature and thoroughly reduce the energy of gasification zone, realize going out stove.Compared with traditional the technology of fire prevention and extinction by nitrogen injection, carbon dioxide is to coal excellent adsorption, and inerting effect is good, and cooling is fast, can lower the temperature and inerting fast and effectively, effectively put out fast by coal seam gasification stove coal body, solves gasification furnace and to go out the slow-footed difficult problem of stove.
2, mining mobile liquid carbon dioxide fire extinguishing device is without the need to supercharging device, is directly released into spontaneous combustionof coal region, improves nearly 10 times than original automatic gas-producing device speed, and blow-off velocity is fast, and good cooling effect, safety is good.
3, carbon dioxide is a kind of industrial chemicals of having many uses, and is numerous chemical plant byproducts, can realizes twice laid, energy-saving and emission-reduction.According to statistics, if purchase nitrogen making machine to add operating cost, fill nitrogen and to go out stove cost 4.8 yuan/cubic metre; And liquid carbon dioxide is by 700 yuan of calculating per ton, 1 ton 600 cubic metres, cost 1.16 yuan/cubic metre, the stove cost that makes to go out reduces 4 times, and efficiency improves about 50 times.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1-grass, 2-storage facilities, 3-flow meter, 4-pressure meter, 5-valve, 6-connecting pipe, 7-conveyance conduit, 8-gasification furnace.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further elaborated.
As shown in Figure 1, a kind of furnace system that goes out fast of mine underground gasification furnace, it is the storage facilities 2 being furnished with storing liquid carbon dioxide at grass 1, between grass 1 and underground gasification furnace 8, be provided with conveyance conduit 7, be connected with valve 5 by connecting pipe 6 between storage facilities 2 with conveyance conduit 7.
The storage facilities 2 of described storing liquid carbon dioxide can be liquefied carbon dioxide tank vehicle, or mining mobile liquid carbon dioxide fire extinguishing equipment, or low temperature liquid carbon dioxide holding tank.
In order to ensure liquid carbon dioxide burst size, connecting pipe 6 is provided with flow meter 3 and pressure meter 4.
Above-mentioned conveyance conduit 7 is the former gasification pipe for gasification furnace, also can again hole from ground to gasification furnace, and connecting pipe 6 to be inserted in boring and sealed.
