Method and device for treating solid combustion exhaust gas

The invention discloses a method and device for treating solid combustion exhaust gas. The method for treating the solid combustion exhaust gas includes the steps of removing at least major amount ofSOX and possibly other pollutants, pre-removing of NOX and removing of NOX and/or other reaction products. The device for treating the solid combustion exhaust gas includes a moving bed reactor for removing SOX, NOX and possibly other pollutants in the solid combustion exhaust gas, a NH3 supply unit and a regeneration unit for an adsorbent; and after air cooled by the adsorbent in the regenerationunit flows out of a cooling section of the regeneration unit, the air can be introduced into a dilution fan in the NH3 supply unit. According to the method and device for treating the solid combustion exhaust gas, simple and convenient production of NH3 can be realized, recycle of gas during the regeneration of the adsorbent is realized, and the gas during regeneration of the adsorbent can be used in the NH3 supply unit.
