The invention provides a cooling
system for the working face of the mine. The invention consists of a ground refrigerating unit, a cooling water recycling device, a cold wind preparing device and a cold wind conveying pipeline. The refrigerating unit and the cooling water recycling device comprise a compressor 7, a condenser 3, a
throttle 8, a
heat exchanger 10, a cooling water pond 1, and a
fresh water pump 2. The cold wind preparing device is a wind spraying chamber 11, and uses the cold media water prepared by the refrigerating unit to spray the wind current, can comprises a wind-inlet grille 16, a wind outlet 20, a water squirting
pipe 17, a
nozzle 18, a
breakwater 19, a wind chamber water falling pond 21, a general water inlet
pipe 22, a general water outlet
pipe 23 and the like. A plurality of rows of vertical water squirting pipes are arranged between the wind-inlet grille and the wind inlet, nozzles are arranged on the top of the water squirting pipes, and the general water inlet pipe introduces the cold media water of the refrigerating unit. The invention adopts the cold media
water spray to process, and prepare the cold wind with the high wind volume, high
temperature difference, high
enthalpy difference; can reduce the times of the heat exchanging process, lower the heat transferring
temperature difference, improve the whole efficiency, and reduce the cold volume waste of the middle course; thereby is applicable for cooling the high-temperature hot and harmful circumstance.
