【 摘 要 】
In order to solve the problem of low concentration coal mine methane (CMM) emission and low utilization rate in coal mine and the underground refrigeration demand of coal mine, this paper puts forward a technology of regenerative thermal oxidation (RTO) to provide waste heat vapor for lithium bromide refrigeration unit, which can effectively solve the problem of low concentration CMM utilization and provide stable heat source output for the refrigeration unit. The integrated process of oxidizing heat supplying to refrigerating unit includes low concentration CMM transportation security system, CMM RTO system and waste heat utilization system. The designed methane concentration is 1.2%, with flow rate 100, 000 Nm3/h, and steam heat of 7537kW. The expected effect of project operation is analyzed, and the economy of the project is demonstrated. The technology of CMM RTO supplying steam for underground refrigeration, through the destruction of methane, and the output of heat for underground refrigeration, has multiple meanings of energy saving and emission reduction, improving the utilization efficiency of coal bed gas in coal mine area, and promoting the safe production of coal mine.【 预 览 】
