Processing system is synthesized to coal fired boiler's flue gas

The utility model discloses a processing system is synthesized to coal fired boiler's flue gas, it is connected between coal fired boiler and chimney. Install the flue gas re -heater between surplus enthalpy exchanger of low temperature side gas cleaning and the chimney, the high temperature side flue gas remains enthalpy exchanger, heat exchanger, circulation medium pipe of the surplus enthalpy exchanger formation of low temperature side gas cleaning, surplus enthalpy exchanger of high temperature side flue gas and flue gas re -heater form another circulation medium pipe. Processing system is synthesized to coal fired boiler's flue gas can absorb the flue gas heat with the hierarchical recycle of waste heat of boiler flue gas efficient, the surplus enthalpy exchanger of high temperature side flue gas, reduces the flue -gas temperature, reduces the working water jet capacity of desulfurizing tower, improves the work efficiency of desulfurizing tower. Reduce cigarette dust content through smoke and dust and the collision of heat exchanger tube bundles sweating water membrane, absorption, utilizing flue gas re -heater heating flue gas, playing and improve flue -gas temperature, promotion flue gas super -heated rate, the increase chimney pulls out lift and reduces the corrosive effects of flue gas to the chimney.
