Application of Gas Full Concentration Utilization,Heating,Electricity and Cooling Triple Supply Technology in Wangfeng Coal Mine
In order to fully utilize the high concentration gas extracted from the surface of Wangfeng Coal Mine,the low concentration gas extracted from the underground of the coal mine,and the exhaust gas in the mine exhaust,and to meet the heating,power supply,and cooling needs of the coal mine,different types of gas are safely transported,mixed,dehydrated,and dedusted through a gas safety transportation and pretreatment system,a gas and mine exhaust blending system,to meet the inlet quality requirements of internal combustion engine generator sets and RTO thermal storage oxidation devices.The internal combustion engine power generation+RTO thermal storage oxidation technology route is used to achieve comprehensive utilization of coal mine gas concentration,making the utilization rate of coal mine exhaust gas reach 100%.The high-temperature flue gas waste heat emitted by the internal combustion engine,cylinder liner water waste heat,and RTO thermal storage oxidation device flue gas waste heat are recovered and used for heating in the coal mine during the heating season,and cooling during non heating seasons,and generate electricity throughout the year,thus achieving the triple supply of coal mine gas heat,cold,and electricity.
