The invention provides a flue gas waste heat recycling system, and belongs to the technical field of heat energy. The flue gas waste heat recycling system comprises a first heat exchanger and a deacidification tower, wherein the first heat exchanger is provided with a first flue gas inlet, a first flue gas outlet, a first water inlet and a first water outlet; the first flue gas inlet communicateswith a flue gas pipeline; the first water inlet communicates with a tap water tube through a pipeline; the first water outlet is used for outputting hot water; a second flue gas inlet is formed in theside wall of the deacidification tower; the first flue gas outlet communicates with the second flue gas inlet through a pipeline; a second flue gas outlet is formed in the top of the deacidificationtower; an alkali liquor tank is arranged on the inner bottom surface of the deacidification tower; a spray device is arranged between the second flue gas inlet and the second flue gas outlet; and thealkali liquor tank communicates with the spray device through a pipeline on which a circulating pump is arranged. The flue gas waste heat recycling system is simple in structure, is convenient to use,is high in waste heat utilization rate, and has a relatively good market popularization and application value.
Description
technical field [0001] The invention relates to the technical field of thermal energy, in particular to a flue gas waste heat recovery and utilization system. Background technique [0002] The temperature of flue gas produced by conventional fuel combustion is relatively high. If the high-temperature flue gas is directly discharged into the atmosphere without treatment, it will cause a great waste of heat energy; in addition, the high-temperature flue gas contains acidic components. If it is directly discharged Into the atmosphere, it will also pollute the environment; therefore, the high-temperature flue gas must be treated before being discharged. [0003] At present, the structure of flue gas waste heat recovery devices on the market usually adopts the method of opening the inlet and outlet of flue gas and the inlet and outlet of the heated medium on the smoke collecting box, and setting a number of heat dissipation pipes arranged in parallel in the smoke collecting box. ...
