背景技术Background technique
矿井主通风机原抽出带有大量热能的乏风正常都没有利用，直接排出到空气当中，造成环境污染，温室效应。煤矿生产过程中伴随着大量余热资源，井下通风、排水、压风、井口防冻热风，设备热排放、地热等，从回风井排放时温度一般在10.0-30.0℃范围、由于受矿尘影响，品位较低，而建筑采暖和井口防冻用热温度要求一般不低于45.0℃。矿井大部分余、废热资源无法直接利用而直接排放。利用矿井乏风源热泵系统从低品位热源中提取余热，提升温度后使其达到供热温度要求，从而替代燃煤、燃油、燃气及电锅炉满足矿井供热及井口防冻需求。所以就需要一种矿井乏风余热回收系统。The exhaust air with a large amount of heat energy drawn out by the mine's main ventilator is not used normally, and is directly discharged into the air, causing environmental pollution and the greenhouse effect. Coal mine production process is accompanied by a large amount of waste heat resources, such as underground ventilation, drainage, compressed air, wellhead antifreeze hot air, equipment heat discharge, geothermal heat, etc. The temperature is generally in the range of 10.0-30.0 ℃ when discharged from the return air well. Due to the influence of mine dust, The grade is low, and the heat temperature requirements for building heating and wellhead antifreeze are generally not lower than 45.0°C. Most of the surplus and waste heat resources in the mine cannot be directly used and discharged directly. Utilize the mine exhaust air source heat pump system to extract waste heat from low-grade heat sources, raise the temperature to meet the heating temperature requirements, thereby replacing coal, oil, gas and electric boilers to meet mine heating and wellhead antifreeze requirements. So there is a need for a mine exhaust air waste heat recovery system.
