Mine waste heat utilization refers to the recovery and utilization of waste heat generated in the mine. In mine production, due to ore mining, mechanical equipment operation, mine ventilation, and other reasons, a large amount of waste heat will be generated. If not recycled, these residual heat will cause energy waste and environmental pollution.
Coal mine exhaust air heat pump system is an energy recovery system that utilizes the residual heat of coal mine underground air to raise the low-temperature residual heat to the available temperature through heat pump technology. This system can effectively utilize the residual heat of underground air in coal mines, achieving the effects of energy conservation and environmental protection.
Specifically, the coal mine exhaust air heat pump system is mainly composed of air source heat pumps, heat exchangers, and pipelines. An air source heat pump can convert the low-temperature residual heat in the underground air of a coal mine into high-temperature heat energy, and then transfer this heat energy through a heat exchanger to the medium to be heated, such as indoor air or water. During the operation of the heat pump cycle, the principle of reverse circulation is used to transfer low temperature heat to high temperature areas, thereby achieving energy recovery and utilization.
In general, the coal mine exhaust air heat pump system can fully utilize the waste heat in the coal mine and convert it into usable heat energy, achieving the effects of energy conservation and environmental protection. However, in practical applications, it is necessary to consider the safety, reliability, and economy of the system, as well as the actual situation of coal mine production, and comprehensively consider the application prospects and benefits of the system.
