Problems solved by technology

Although very high removal efficiency can be achieved, problems such as large equipment volume and high input cost limit the widespread use of the technology
The inventor found that for small industrial boilers such as waste incinerators, due to cost and volume limitations, the removal efficiency of harmful gases and carcinogens is very limited

Embodiment

[0084] A waste incinerator system such as Figures 1~3 As shown, it includes: furnace outlet 1, chimney 2, tertiary tuyere 21, secondary tuyere 22, primary tuyere 21, air cap baffle 3, peripheral steel frame structure 4, air inlet 5, feed port 6, isobaric air chamber 7 , Cooling slag pipe 71, slag removal port 8, furnace main body 9, boiling vertical section chlorine inhibitor 91, boiling section catalytic refractory material 92, suspension section catalytic refractory material 93.

[0085] The top suspension section catalytic refractory 93 can replace the original suspension section furnace wall refractory material in the furnace and the furnace top furnace wall refractory material. In actual operation, it can combine the original CO of the flue gas to reduce NO in the flue gas x Catalytic removal is carried out.

[0086] The boiling section catalytic refractory material 92 replaces the original boiling section furnace wall, air distribution plate 3 and surface refractory ma...

Abstract

The invention discloses a garbage incinerator system and a method for catalytic removal of garbage incinerator flue gas purification furnace, comprising a garbage incinerator, the flue gas outlet of the garbage incinerator is connected to a flue, the flue gas outlet of the garbage incinerator is provided with a heat exchange device, and the garbage incinerator The garbage input port of the furnace is equipped with a mixing device, which is connected to the garbage source and the chlorine inhibitor source. The furnace wall of the boiling section of the garbage incinerator furnace is equipped with an insulating high-temperature catalyst layer, and the furnace wall of the suspension section of the garbage incinerator furnace wall and the inner wall of the flue are provided with insulation Medium-temperature catalyst layer and heat storage ball layer are laid on the surface of the heat exchange device; chlorine inhibitor is formed by compounding sulfur-containing carbon and calcium oxide; heat-insulating high-temperature catalyst is formed by compounding refractory material and high-temperature catalyst; heat-insulating medium-temperature catalyst is formed by compounding refractory material and medium-temperature catalyst Formation; heat storage balls contain catalytically active components. The invention can effectively reduce the cost of the out-of-furnace treatment of flue gas and fly ash, effectively realize the inhibition in the process of dioxin formation and the decomposition of incineration products.

Description

technical field [0001] The invention belongs to the technical field of waste incineration, and relates to a waste incinerator system and a method for purifying the furnace chamber of waste incineration flue gas by catalytic removal. Background technique [0002] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.
