[0002] Incinerators can be used to treat toxic and hazardous gases, medical waste, household waste, animal carcasses, and more. After incineration, dry deacidification technology can be used to deacidify the flue gas. Dry deacidification is a technique used to reduce the acid gases generated during the incineration process. This technology primarily involves injecting an alkaline deacidifier, such as slaked lime (Ca(OH)2), into the incinerator. This reacts chemically with the acid gases in the flue gas, neutralizing them and producing harmless neutral salt particles.

[0003] The salts and unreacted particles formed after the reaction are partially discharged from the bottom of the deacidification equipment to form slag; part enters the flue gas system after the furnace to form fly ash, but some impurities will stick to the inner wall of the deacidification equipment and cannot be effectively cleaned. Therefore, it is necessary to propose a deacidification device for a domestic waste incinerator. Utility Model Content
