Condensation water recycling device based on exhaust -heat boiler low temperature flue gas

The utility model discloses a condensation water recycling device based on exhaust -heat boiler low temperature flue gas, including exhaust -heat boiler (6), flue (1), chimney (10), first water pump (2) and moisturizing case (3), its characterized in that still wraps rubbing board formula heat exchanger (8), collection cylinder (4) and condensate water collecting box (7), during plate heat exchanger set up the front end flue between exhaust -heat boiler (6) and chimney (10), plate heat exchanger's soft water outlet linked to each other with exhaust -heat boiler's water feeding pipe, and exhaust -heat boiler's steam conduit exit linkage collection cylinder (4), and condensate water collecting box (7) set up in plate heat exchanger's cold water opening below. Through set plate formula heat exchanger in the flue, abundant low temperature recovery flue gas waste heat improves the boiler feed water temperature, improves the gas utilization efficiency, retrieve the flue gas condensate water, as boiler water supplem
