Example Embodiment

[0015] Such as figure 1 Shown: it is composed of a feeding device 1, a pyrolysis carbonization furnace body 2, and a slag screw 3 which are arranged and connected in sequence;

[0016] The feeding device 1 is composed of a feeding port 1-1, an extrusion cavity 1-4, a pusher 1-2, and a solid material check valve 1-3. The extrusion cavity 1-4 is a cylindrical channel, The feed port 1-1 is connected to the front side wall of the extrusion cavity, the pusher 1-2 is located in the extrusion cavity 1-4 below the feed port 1-1, and the solid material check valve 1-3 is located in the extrusion cavity. The chambers in the back section of chambers 1-4; during use, the garbage passes through the solid material check valve of the feeding device and the compression and propulsion of the pusher, so that the garbage layer is compressed and compacted and the air is reduced to the pyrolysis furnace. Push the garbage into the pyrolysis carbonization furnace, and prevent the pyrolysis gas in the f...

Abstract

The invention relates to a reflux rotating household garbage pyrolysis carbonization furnace system and a garbage disposal process. The system is composed of a feeding device, a pyrolysis carbonization furnace body and a spiral slag tapping device, all of which are arranged and connected in sequence together; and a gas/heat circulating device connected with the pyrolysis carbonization furnace body is combined for the completion of the system; and with control on the temperature of the pyrolysis carbonization furnace body and the garbage retention time, the disposal of the household garbage and organic solid wastes is realized. The reflux rotating household garbage pyrolysis carbonization furnace system is capable of effectively disposing the household garbage and the organic solid wastes, and has the advantages of noncoking, non-blockage, good heat transfer and mass transfer effects and high disposal efficiency; the garbage is decomposed into combustible gases and slags under the conditions of heating and no oxygen; and continuous operation including continuous feeding, continuous pyrolysis and continuous slag tapping can be realized.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a countercurrent transfer domestic waste pyrolysis carbonization furnace system and a waste treatment process. Background technique [0002] According to statistics, my country's annual domestic waste production is about 310 million tons. Huge domestic waste is increasingly harmful to the environment. Reducing, harmless, and recycling waste is an important issue in environmental protection. [0003] Domestic waste incineration is an important means of reduction and harmless treatment, but the dioxins, heavy metals, and acid gases produced by incineration are likely to cause secondary environmental pollution. To eliminate these toxic and harmful substances in the flue gas, complex treatment must be established Facilities and consume a large amount of treatment agents such as lime and activated carbon. At the same time, the fly ash produced by flue gas treatment is ha...
