[0031] Specifically, when using the boiler waste heat heating device to treat the boiler flue gas, the flue gas generated by the boiler is transported to the inside of the serpentine heat exchange tube 5 through the air inlet pipe 6. The water body inside the waste heat recovery bin 101 absorbs the heat of the flue gas inside the serpentine heat exchange tube 5. The flue gas after waste heat recovery treatment enters the water washing bin 102. The water body inside the F-shaped three-way water inlet pipe 4 enters the inside of the spray seat 9, and the flue gas entering the water washing bin 102 is washed through the spray seat 9, so that the solid pollutants and water-soluble pollutants in the flue gas settle to the bottom of the water washing bin 102.
