Background technology
The main component of coal mine gas is a methane, is a kind of greenhouse gases, and its greenhouse effects are 21 times of carbon dioxide.In recent years, China is more than 150 hundred million Nm by coal mine methane discharging methane every year
3If this ventilation air gas is used, amount to 2,300 ten thousand tons of standard coals approximately, can reduce discharging 200,000,000 tons of equivalent carbon dioxide.Coal mine wind-lack gas concentration is very low, be difficult to utilize conventional burners directly to be burnt, effectively utilizing method at present is to adopt hot counter flow oxidation technology (Thermal Flow Reversal Reactor, be called for short TFRR) and catalysis counter flow oxidation technology (Catalytic Flow Reversal is called for short CFRR).The basic functional principle of these two kinds of counter flow oxidation technology is identical substantially with structure, and the main distinction is that CFRR has used oxidation catalyst, has reduced the needed temperature of gas oxidation.The MEGTEC company of Sweden adopts the methane in the TFRR technical finesse coal mine methane, and reclaims its energy.MEGTEC company has installed 4 cover TFRR in 2004 at Australia's ratio with than opening up company West Cliff colliery, brings into operation at the beginning of 2007, about 20% coal mine methane in West Cliff colliery can be converted into the useful energy, and generating capacity is 5MW; In one tame colliery, Dengfeng City, China Henan 1 cover TFRR was installed in 2007, has been specifically designed to the destruction ventilation air methane.Units such as the Shandong Technology Univ of China, Shengli Oil Field Shengli Power Machinery Group Co., Ltd, the black bavin new forms of energy in Zibo Co., Ltd also independent development successively the hot counter flow oxidation device of coal mine wind-lack gas, and carried out application test research at colliery scene, begun the demonstration operation now.Nineteen ninety-five Canada mineral and energy technology center (CANMET) begin to research and develop coal mine wind-lack gas catalysis countercurrent reaction (CFRR) technology, develop laboratory scale catalytic methane countercurrent reaction chamber now, and on this device, carried out coal mine wind-lack gas catalytic oxidation simulated test.On the whole, the gas in the coal mine methane can be administered and utilize in hot countercurrent reaction chamber and catalysis countercurrent reaction chamber effectively.But, have only hot countercurrent reaction technology successfully to carry out commercial application at present at colliery scene from the practical application angle.But adopt TFRR technical finesse coal mine wind-lack gas also to exist following problem: (1) TFRR takes up an area of relatively large, for example will handle 150m with the TFRR unit of MEGTEC company
3The gas of/s, its plant area area is about (63 * 14.62 * 4.49) m; (2) oxidation bed of TFRR is made of a large amount of ceramic honey combs, and in general problems such as ceramic honey comb can ftracture after long-term use the, fragmentation and obstruction will change one time ceramic honey comb every year, and maintenance cost is too high; (3) drag losses of TFRR is very big, and generally more than 8000KPa, the energy consumption of blower fan is very high; (4) air-flow in the oxidation bed of TFRR need constantly be changed direction, and maintains the middle part of oxidation bed to guarantee high-temperature area, and control degree is automatically had relatively high expectations, and operating technology requires very high.These subject matters have strengthened the difficulty that the TFRR technology is applied.
