Abstract

The utility model relates to a mine water waste heat extraction and utilization system, and belongs to the technical field of mine waste heat utilization. The mine water waste heat extraction and utilization system is characterized in that a heat pump water source unit (2) is included, the heat pump water source unit (2) is provided with a mine circulating water feeding pipe (3) and a water returnpipe (4), the heat pump water source unit (2) is connected with a mine water lifting device through he mine circulating water feeding pipe (3), the heat pump water source unit (2) is connected with awater return pool (5) through the water return pipe (4), and the mine water lifting device communicates with a downhole roadway (9). The mine water waste heat extraction and utilization system fullyutilizes the storage function of the abandoned roadway, realizes the purposes of temperature rise for energy storage in summer and heat release for energy release in winter of a roadway water body, reasonably stores, transfers and extracts energy, can maintain the operation of the water source heat pump unit, can realize zero discharge of external circulating water and is considerable in economicand social benefit.

Description

technical field [0001] A mine water waste heat extraction and utilization system belongs to the technical field of mine waste heat utilization. Background technique [0002] Heating in winter, cooling in summer, and heating for bathing in coal mining areas are basically provided by water source heat pump systems. Mine water, as the external circulation medium of the system, plays the role of energy exchange and transfer, and maintains the normal operation of the system. After the mine is shut down, the water source of the mine will not be obtained from the underground, and the water source heat pump will not be able to start operation at that time. [0003] The water source heat pump unit is equipped with two water cycles, namely internal circulation and external circulation. The internal circulation sends the hot water in winter or cold water in summer to the user's cold and heat exchanger. The user can control the indoor temperature by controlling the air volume flowing t...
