Abstract

The invention provides a return air and waste heat recovery utilization system of a mine. The system comprises a wind guiding device, a wind heat exchanger assembly, a water heat exchanger assembly, ahot water transmission and distribution device and a hot water utilization device; one end of an air channel of the wind guiding device is connected to an air return well of the mine, and the other end of the air channel is connected with the wind heat exchanger assembly; the hot water transmission and distribution device comprises a hot water supply pipe and a hot water return pipe, one end of each of the hot water supply pipe and the hot water return pipe is connected to the water heat exchanger assembly, and the other end of the same is connected with the hot water utilization device; andthe wind heat exchanger assembly is connected with the water heat exchanger assembly via a copper pipe, the wind heat exchanger assembly absorbs heat in the return air, and the water heat exchanger assembly transfers heat absorbed by the wind heat exchanger assembly to circulation water in the hot water transmission and distribution device.

Description

Technical field [0001] The invention relates to the field of mine waste heat recovery, in particular to a mine return air waste heat recovery and utilization system. Background technique [0002] Mine return air is a high-quality waste heat resource, but at present, mine return air is generally directly discharged into the atmosphere, and a large amount of waste heat resources are not effectively used, which not only causes energy waste, but also exacerbates the greenhouse effect. [0003] In the prior art, the mine return air waste heat recovery and utilization system mainly uses spray water to spray the mine return air, thereby absorbing the heat in the return air, and the spray water that absorbs the heat is stored in a collecting tank, and then the water source heat pump The spray water is converted into hot water with a higher temperature for use in the mining area. [0004] Among the above technologies, the overall structure of the recovery system composed of sprinkler equipme...
