This invention discloses a wet-type flue gas waste heat recovery device which is integrated into one with a flue and a chimney; spray header tubes are arranged in a chimney and a horizontal flue; a spraying hole with larger diameter and which can not be blocked is upturned, and on the top of which a spraying drip thinning device is provided; the time for drip thinning and the drips staying in the flue gas for interaction is comparatively long; the effect on eliminating the flue gas, lowering the temperature and recovering the waste heat is good. The bottom of the flue is provided with a reflux weir which separates the sewage sprayed down from the up stream and the down stream of the flue according to the different temperature of the sewage and the separated sewage flows to a hot water tank and a circulation tank, thus effectively increasing the temperature of the hot sewage obtained from the spraying and lowering the facility charge and running cost of a clean water heat exchanger; outside the part with highe
