Abstract
The utility model provides a coal underground gasification furnace. The coal underground gasification furnace is arranged on a base rock and a gasification coal seam. An air inlet hole is communicated with a gasification channel, the gasification channel is communicated with an air flow channel and the air flow channel is connected with an air outlet hole. The air outlet hole is provided with a coal gas cooling device. The utility model has the advantages of that improving the unblocked safety coefficient of the air flow channel and solving the use of short distance multiple coal seam coals, and the gasification coal seam of the gentle inclined angle.
Description
Technical field
The utility model relates to coal seam, mine development technique, is a kind of coal underground gasifying furnace.
Background technology
At present, the deficiency that the gasifying underground coal stove technology of China exists is: generally be could realize in coal seam, anxious inclination angle, can not be used for the on average gasification zone, ore deposit about 8 degree of seam inclination, can not be used for balk, gasification zone, the closely spaced ore deposit of multilayer coal, and be the one-stor(e)y furnace structure, this coal underground gasifying furnace also cannot say for sure to demonstrate,prove the continuity of gasification, and the body of heater that is used to gasify can not be realized sealing; Can not solve problems such as the hole pipe expands with heat and contract with cold.
Summary of the invention
The purpose of this utility model is, a kind of coal underground gasifying furnace is provided, and makes it have following advantage: improve the unimpeded safety factor of gas channel, solve closely multiple seam coal resources utilization; Gasification coal seam etc. when low-angle dip.
For achieving the above object of the present utility model, be achieved through the following technical solutions, it is arranged on basement rock and the gasification coal seam, air inlet communicates with gasification tunnel, gasification tunnel communicates with gas channel, and gas channel is connected with venthole, and the coal gas heat sink is installed at the venthole place.Gasification tunnel and gas channel all are set to 2, make body of heater be duplex.The coal gas heat sink is that the airflow hole pipeline is installed at the venthole place, mounting sleeve on the airflow hole pipeline, and sleeve pipe is connected with gas flue.The ripple expansion bend is installed on the sleeve pipe.
The utility model has the advantages that, improved the unimpeded safety factor of gas channel, solved closely multiple seam coal resources utilization, can be at the low-angle dip coal seam gasification, and efficiently solve the problem of expanding with heat and contract with cold of hole pipe, but continuity gasification etc.
Description of drawings
Accompanying drawing 1 is the utility model structural representation; Accompanying drawing 2 is structural representations of coal gas heat sink in the accompanying drawing 1.
8 is basement rock among the figure, the 7th, and the gasification coal seam, air inlet 1 communicates with gasification tunnel 2, and gasification tunnel 2 communicates with gas channel 6, and gas channel 6 is connected with venthole 11, and coal gas heat sink 10 is installed at venthole 11 places.Gasification tunnel 2 and gas channel 6 all are set to 2, make body of heater be duplex.Coal gas heat sink 10 is that airflow hole pipeline 16 is installed at venthole 11 places, and mounting sleeve 15 on the airflow hole pipeline 16, and sleeve pipe 15 is connected with gas flue 12.Ripple expansion bend 14 is installed on the sleeve pipe 15.Air inlet 1 of the present utility model, be used to carry gasifying agent, when gasifying agent passes through air inlet 1 through gasification tunnel 2, finish the also logical reaction of gasification in zoneofoxidation 3, reducing zone 4 and dry distillation zone 5 and produce coal gas, carry gasifying agent and coal gas through gas channel 6 again, after venthole 11 coal gas is imported in the gasholder.Because the gas temperature that airflow hole pipeline 16 is flowed through is high more than 300 ℃, expanding with heat and contract with cold of pipeline is serious, so between gas pipe road junction and airflow hole pipeline 16, increase sleeve pipe 15, airflow hole pipeline 16 is not directly contacted with gas flue 12, and ripple expansion bend 14 is used to solve slightly expanding with heat and contract with cold of sleeve pipe 15.The mean obliquity that coal gas low-angle dip described in the utility model is the coal seam is about 8 degree.9 is topsoil among the figure, the 13rd, and valve.
