基于热泵技术的白雾防治系统设计

摘要

Based on the technology of heat pump,the device of anti-mist is designed,which can remove the mist through cooling down of the moist air by the evaporator of heat pump until the dew-point temperature,then the water vapor would condense into liquid water and separate from air,cooling the moist air sequential y until its temperature is the same as ambi-ent temperature,then discharge it into atmosphere,this procedure realized the hot wet air emissions without mist.%基于热泵技术设计了一套白雾防治系统，可实现白雾的去除———将高温的热湿空气，经过热泵蒸发器进行冷却降温至其露点温度后，水蒸气凝结为液态水后析出，继续降温至环境温度后将其排至大气，实现了热湿空气的无白雾排放。冷却除湿回收了湿空气中的水分，节约了宝贵的水资源，经计算年可节水1．4万吨，而热泵冷凝器可以进行供暖或者热水制取，因此系统实现了热泵制冷量和制热量的全部利用，热泵的COP可达8，系统的节能效果显著。
