The present invention provides a kind of absorption boiler flue gas treatment systems of twin-stage, including condensing unit, first absorber, first regenerator, second absorber and Second reactivator, boiler sequentially concatenates the first regenerator of connection by flue, condensing unit, first absorber, second absorber, first regenerator is connected to by the first inlet tube and the first drain pipe with the first absorber, first regenerator is connected to by jet chimney with Second reactivator, Second reactivator is connected to by the second inlet tube and the second drain pipe with the second absorber, Second reactivator is connected to by combustion-aid air pipe with boiler.The present invention can achieve the effect that with lower cost-effective Mist heat recovering and moisture, the content for avoiding soluble nitrogen oxide in flue gas that nitrogen oxides in smoke evacuation is polluted, reduced to hygroscopic solution. |
