Zusammenfassung:	A defrosting dust cleaning device that is used for mine heat recovery heat pump unit heat exchanger of airing exhaust relates to a defrosting dust cleaning device. The utility model discloses a heat recovery heat exchanger of the well head of airing exhaust is arranged in the slope. Structurally, the pressure sample point has been put respectively to heat recovery heat exchanger's inside and outside both sides, and the pressure signal of two pressure sample points conveys the pressure differential controller. Airing exhaust in the well, having put ji water sedimentation chi under the well head, water filter is equipped with to the bottom on water pipe way no. 1, leads to the water in the extraction collection water sedimentation pond of pipe way by the water pump, carries water to installing in the washing nozzle of the high -end inboard of heat recovery heat exchanger through water pipe way no. 2, and the washing nozzle water spray is to the heat recovery heat exchanger dust cleaningoperation that defrosts.
