Waste heat recycling device

Technical Field

The utility model relates to the technical field of waste heat recovery, in particular to a waste heat recovery and utilization device.

Background

During the coal mining process, a large amount of mine wastewater can be gushed out. Mine waste water is continuously discharged all the year round, and the temperature is constant at 18-20 ℃. At present, in order to reasonably utilize the waste heat of mine waste water, the mine waste water is intensively discharged into a water collecting tank through a drainage device, the waste heat of the mine waste water in the water collecting tank is extracted through a water source heat pump unit, and the mine water after heat extraction is directly discharged back to the water collecting tank.

In the practical application process, the temperature of the mine wastewater at 18-20 ℃ is reduced after heat is extracted by a water source heat pump unit. The low-temperature mine water subjected to heat exchange is directly discharged into the water collecting tank, so that the overall water temperature in the water collecting tank is greatly reduced, and the waste heat recovery efficiency of the mine waste water is greatly reduced due to repeated circulation. If the low-temperature mine water after the waste heat is extracted is directly discharged, not only is the waste of water resources caused, but also the environment is polluted. Therefore, we propose a waste heat recycling device for mine waste water.
