Description
Technical field
The utility model relates to a kind of liquid gas with defeated underground gasification stainless steel compound continuous-tube.
Background technology
Coal is the basic industry of Chinese national economy development, and by the restriction of traditional pit mining technical level, along with the increase gradually of mining rate, a large amount of mine abandonments or industry are scrapped, and abandons existing more than 30,000,000,000 tons of resource reserve at present.Traditional pit mining can be difficult to the poor girdle of exploitation or exploitation economy and safety, dark producing coal layer, " three times " pressure coal and high-sulfur, high-carbon, high gas layer and exploit further by the application of coal underground gasification technology, substantially increases the utilization rate of coal resources.Underground gasification is the gaseous mixture by injecting oxygen and water or oxygen and water vapour to coal seam, the gasification reactions such as coal generation pyrolysis, reduction and oxidation, and water vapour provides the hydrogen needed for reaction, and reduces temperature, and the coal gas of generation is drawn from another boring.When oxygen and water inject respectively, need to hang equipment by two and successively probe into corresponding oxygen hose and water pipe to coal seam, the activity duration is long, and production efficiency is low; When oxygen and water vapour are injected to coal seam jointly by a pipe, because fed distance is long, the concentration of oxygen and water vapour changes, and gasification result is poor.
Summary of the invention
The utility model is to solve the problems of the technologies described above, and provides one to improve gasification result, reaches best gas production, shortens activity duration, the liquid gas of enhancing productivity with defeated underground gasification stainless steel compound continuous-tube.
Technical solution of the present utility model is: a kind of liquid gas is with defeated underground gasification stainless steel compound continuous-tube, comprise outer tube, its special character is: be fitted with interior pipe within the outer tube, the length of described outer tube and interior pipe is 1200m ~ 2500m, and between described inner and outer tubes, be arranged at intervals with the bracing frame that multiple axis is evenly arranged, between described inner and outer tubes, thermocouple is set vertically, described thermocouple has multiple point for measuring temperature, the point for measuring temperature of bottom is near the bottom of outer tube and interior pipe, and described interior pipe, outer tube and bracing frame are stainless steel.
Described outer tube diameter is 38.1mm ~ 89mm.
Described thermocouple is installed in stainless steel sleeve pipe, and described stainless steel sleeve pipe clamp is located at the gap location of inner and outer pipes.
Support frame as described above is made up of inner sleeve and along the circumferential direction uniform radial support block.
The spacing of adjacent two bracing frames is 2m-3m.
The beneficial effects of the utility model are:
1, inside and outside sleeve structure is adopted, oxygen is injected in inside pipe, for underground coal gasification(UCG) provides combustion adjuvant, water filling in the circular passage between inner and outer tubes, the water injected plays cooling effect for interior pipe and combustion head and provides water vapour for underground coal gasification(UCG), utilize thermocouple measurement combustion head place temperature, then make underground coal gasification(UCG) reach optimum state by the flow controlling to inject oxygen and water.Because in logical oxygen, pipe is inserted in the outer tube of water flowing, only need can be visited to the coal seam of underground by a hole, shorten the activity duration, improve production efficiency.
2, thermocouple is arranged multiple point for measuring temperature, the temperature of in pipeline each section can be monitored in real time, meet user's requirement.
3, each parts adopt stainless steel, and acid-fast alkali-proof is high pressure resistant.
