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.
