Garbage incinerator system and garbage incineration flue gas purification hearth catalytic removal method

Abstract

The invention discloses a garbage incinerator system and a garbage incineration flue gas purification hearth catalytic removal method. The garbage incinerator system comprises a garbage incinerator; a flue gas outlet of the garbage incinerator is connected with a flue; a heat exchange device is arranged at the flue gas outlet of the garbage incinerator; a garbage throwing opening of the garbage incinerator is provided with a mixing device; the mixing device is connected with a garbage source and a chlorine inhibitor source; a heat-preservation high-temperature catalyst layer is arranged on the furnace wall of a boiling section of a hearth of the garbage incinerator; heat-preservation medium-temperature catalyst layers are arranged on the furnace wall of a suspension section of the hearth of the garbage incinerator and the inner wall of the flue; a heat storage ball layer is laid on the surface of the heat exchange device; the chlorine inhibitor is formed by compounding sulfur-containing carbon and calcium oxide; the heat preservation high-temperature catalyst is formed by compounding a refractory material and a high-temperature catalyst; the heat-preservation medium-temperature catalyst is formed by compounding a refractory material and a medium-temperature catalyst; and catalytic active components are contained in the heat storage balls. According to the garbage incinerator system and the garbage incineration flue gas purification hearth catalytic removal method, the external treatment cost of the flue gas and the fly ash can be effectively reduced, and inhibition of dioxin during generation and decomposition of products obtained after incineration are effectively achieved.
