| description | The invention relates to the technical field of energy recycling, and provides a comprehensive utilization method for mine ventilation air methane heat energy. Comprising the following steps that ventilation air methane entering a pipeline is subjected to heat exchange with a cooling medium flowing into a first heat exchanger in the first heat exchanger; water vapor in the ventilation air methane passing through the first heat exchanger exchanges heat with the first heat exchanger and is condensed into water; ventilation air methane passing through the first heat exchanger enters the second heat exchanger through drainage, enables a cooling medium in the second heat exchanger to sublimate to generate gas and is introduced into the compressor; compressing the gas introduced into the compressor, so that the gas becomes high-temperature and high-pressure gas; and the high-temperature and high-pressure gas exchanges heat with cold water to obtain hot water. The system has the beneficial effects that the ventilati |
