Abstract

The invention relates to a system for directly recycling mine return air afterheat. The system comprises a return air shaft, an intake shaft, a guide mechanism, a heat exchange mechanism and an energystorage mechanism; and the guide mechanism, the heat exchange mechanism and the energy storage mechanism are arranged between the return air shaft and the intake shaft. The system is prominent in economical benefits and social benefits of no increment of the ventilation resistance of a mine main fan, low energy consumption, high heat efficiency, low production cost, capability of saving a lot ofenergy, low operation cost, environmental protection, capability of effectively reducing environmental pollution, popularization and application.

Description

technical field [0001] The invention relates to air and air heat recovery and heat exchange technology, in particular to a system for direct recovery and utilization of mine return air waste heat. Background technique [0002] Coal mine is a huge heat accumulator with abundant geothermal resources. The air entering the coal mine is constantly exchanging heat with the coal mine roadway, electromechanical equipment, shower water, etc., and finally, the air temperature and the ground temperature of the coal mine reach equilibrium. The ground temperature of the coal mine is basically constant, so that the temperature of the return air of the coal mine is basically constant throughout the year, and is little affected by the outside air temperature. On the other hand, the heat dissipation of underground electromechanical equipment (20% of the power of general electromechanical equipment), coal dust oxidation heat dissipation, groundwater heat dissipation, personnel heat dissipati...
