Abstract

The invention discloses a depressurization device for an underground cooling system, belongs to a device for regulating pressure of running water, in particular to a depressurization device by converting water potential energy under high pressure to kinetic energy. The depressurization device is characterized by consisting of a frozen water conveying system and an underground high-temperature water return system which are respectively connected with an overground freezing system and an underground heat exchange device; the frozen water conveying system comprises a water turbine water inlet electric valve, a water turbine and a water turbine water outlet electric valve which are sequentially connected from top to bottom; the underground high-temperature water return system comprises a return water pump water inlet electric valve, a return water pump and a return water pump water outlet electric valve; and a power transmission device is arranged between the water turbine and the water pump. According to the depressurization device, the water turbine is driven to put the return water pump in motion by using pressure and potential energy of high-pressure frozen water, so that the high-pressure frozen water is depressurized, and simultaneously, energy is saved for the underground cooling system.

Description

Technical field [0001] The present invention belongs to a flowing water pressure regulating device, in particular a pressure reducing device that adopts the variable energy of high-pressure water potential energy. Background technique [0002] Under the conditions of deep mine mining, the ground temperature continues to rise, and the heat damage is also increasing, which seriously affects the efficiency of workers and their physical and mental health, and may even lead to the occurrence of some malignant mine accidents, which will bring safety to the mine’s production and daily management. There is a great threat. Therefore, a well temperature reduction system is needed to reduce the temperature of the roadway working surface. However, due to the depth of the well, the pressure of the chilled water in front of the workpiece is very high, which can reach more than 10Mpa. Direct use of high-pressure chilled water is dangerous, and the tunnel cooler cannot withstand high pressure, ...
