Direct contact residual heat from flue gas device

The utility model discloses a direct contact residual heat from flue gas device, including the recovery tower, be equipped with the flue gas entry, the exhanst gas outlet that supply the flue gas to flow on the recovery tower to and be used for spray cooling water main spray tube, locate a plurality of nozzles on the main spray tube, main spray tube is followed the axis setting of recovery tower, it is a plurality of the spray direction of nozzle is to radiating, just all around the flue gas entry the line of exhanst gas outlet with the spray direction of nozzle alternately. Adopt this kind of structure, can reduce the collision loss of liquid drop, reduce smoke resistance, can reduce acceleration of gravity's influence again, prolong the dwell time of liquid drop, improve mass transfer heat transfer capacity, and then improve the efficiency that the flue gas was retrieved. 本实用新型公开了种直接接触式烟气余热回收装置，包括回收塔，所述回收塔上设有供烟气流动的烟气入口、烟气出口，以及用于喷淋冷却水的主喷管、设于所述主喷管上的多个喷嘴；所述主喷管沿所述回收塔的轴线设置，多个所述喷嘴的喷射方向向四周辐射，且所述烟气入口、所述烟气出口的连线与所述喷嘴
