Mine ventilation cooling and waste heat utilization system

The utility model discloses a mine ventilation cooling and waste heat utilization system. The mine ventilation cooling and waste heat utilization system comprises a heapstead which is located on the outer side of a wellhead, wherein a plurality of air heat exchangers are mounted on the side wall of the heapstead; one end of a refrigeration heat pump unit in a machine room is connected with the air heat exchangers by a cold and hot medium water circulation pipeline; the other end of the refrigeration heat pump unit is connected with a cooling tower on the machine room by a cooling tower water circulation pipeline; the refrigeration heat pump unit is connected with a mine water tank by a mine water circulation pipeline. According to the mine ventilation cooling and waste heat utilization system, cold air which is subjected to cooling and dehumidifying is input under a shaft in summer, the temperature under the shaft is effectively reduced, the humidity under the shaft is also effectively reduced, the whole damp and hot environment of the wellhead and under the shaft is improved, the comprehensive cooling and dehumidifying effects are realized, not just the cooling and dehumidifying of a local work face are realized, the whole environment of work under the shaft is improved, the work efficiency of miners is improved, the safety production of a coal mine is ensured, and the aims of cooling and dehumidifying under the shaft are realized; in winter, the waste heat of mine water with high temperature can be recycled to be used for thermal insulation of the wellhead, and the aims of energy saving and consumption reduction are realized.
