Description
Technical field
The present invention relates to a kind of transportation and method for using of coal-seam gas, relating in particular to a kind of in the Coal Transport process is that medium absorption coal-seam gas is for carrying the energy, the transportation of the supply vehicle energy and method for using with the coal.
Background technique
The modernization of World Economics has benefited from fossil energy, like oil, rock gas and coal etc.; Yet this economic resource carrier of fossil energy will be in the promptly approaching exhaustion of the 21 century first half, the interruption of fossil energy and raw material chain; Will cause the aggravation of world crisis and conflict, finally ruin Modern Market Economy, for alleviating energy crisis; The R and D of new energy extensively are devoted in countries in the world; Biomass energies such as for example renewable new energy such as solar energy, wind energy, ocean energy, and hydrogen, methyl alcohol, ethanol, butanols, but the development cost of new energy is extremely expensive; And only have 10% of not enough fossil feedstock generation electric power to be used for modern humans's production and life, can in half a century from now on, replace fossil energy still be a unknown number comprehensively.
Fortunately, have a kind of tax to exist in the coal seam with methane to be the unconventional rock gas of main component to be called coal-seam gas, methane accounts for 80%-90%; Be the gas that produces in the coalification works,, claim gas again with the coal coexistence; Be a kind of potential clear energy sources, reserves are very abundant, estimate according to International Energy Agency; The coal bed gas resource of land coalfield, whole world buried depth above 2000 meters is about 260,000,000,000,000 m3, is that the twice of conventional gas explored reserve is many, and China's coal bed gas resource is abundant; The whole nation has 14 greater than the coal-seam gas basin that contains of 5,000 hundred million m3; Buried depth 2000m is about 36,000,000,000,000 m3 with shallow coal-seam gas geological resource amount, and 1000m accounts for 38.8%, 28.8% and 32.4% of national coal bed gas resource geology total amount respectively with the coal-seam gas geological resource amount of shallow, 1000-1500m and 1500-2000m.Though because a series of technical barriers, the utilization ratio of China's coal-seam gas present stage is very low, a large amount of existence of this existing energy definitely are one of desirable alternative energy sources of traditional fossil energy.
And the transportation of the energy, especially like this heavy fuel transport of coal, because gasoline, diesel-fuel price are growing, and the distance of transporting the coal in the North to the South; The cost that expends in transportation process is very high, simultaneously, along with the exploitation of coal a large amount of coal-seam gas is arranged at coal district, discharges owing to transporting to utilize; Not only befouling environment but also waste energy, however coal-seam gas has a very important characteristic; Promptly be prone to by porous crack material absorption such as coals, so the present invention, from the easy characterization of adsorption angle of the comprehensive utilization energy and coal-seam gas; Propose a kind of improved mobile haulage vehicle device, in transportation coal, carry a large amount of coal-seam gas of transportation; Be used for the energy resource supply of vehicle in transit, make full use of the energy, practice thrift cost of transportation.
Summary of the invention
The objective of the invention is to make full use of the coal-seam gas energy of coal district, in the process of transportation coal, be used for the vehicle energy resource supply, reducing a kind of of cost of transportation greatly is the transportation and the method for using of medium absorption coal-seam gas with the coal.
The present invention realizes through following technological scheme:

When needing energy resource supply in transit, can connect the pipeline between material feeding mouth (7) and the motor vehicle fuel cylinder, Open valve gradually, coal-seam gas is desorb progressively, and the promotion of pressure difference in the fuel tank through the motor energy supply.Simultaneously, combustion tail gas that installs and the following end entrance of heat exchanging tube (2) are connected, make thermal source pass through the coal-seam gas in the heat exchanging tube heated sealant jar (1), promote the desorb of coal-seam gas also to make full use of automobile exhaust heat.
After the sealing haulage vehicle arrives the destination, complete if the coal-seam gas of carrying is also utilized, can be with storing for future use after its whole desorbs; The coal-seam gas desorb is dismantled circular head (4) after accomplishing once more, and coal from the end socket discharging, is accomplished transportation process.
In the said apparatus of the present invention:
1, pressure gauge is conventional standard piece.
2, safety valve is conventional totally enclosed type safety valve.
3, inlet pipeline gos deep into bottom of device, is convenient to filling of gas.
4, sealing cover is a demountable structure, has seal washer, is connected sealing with tank body through flange.
5, heat exchanging tube is common heat exchange structure, includes but are not limited to snakelike formula, tube still type etc.
6, tank body is common middle pressure tank body, and its material is common pressure-resistant material, includes but are not limited to Q345R, 20R, 16MnR etc.
7, coal-seam gas includes but are not limited to methane, ethane, butane equal energy source gas.
The present invention has advantage:
