Large air pyrolysis treatment device of urban domestic garbage

Abstract

The invention discloses a large air pyrolysis treatment device of urban domestic garbage. The large air pyrolysis treatment device is provided with a treatment chamber main cabin and an isolating cabin, wherein the treatment chamber main cabin is internally provided with a transporting channel which is formed by a plurality of layers of transporting belts and realizes zigzag reciprocating circulation; the treatment chamber main cabin is internally provided with a thermoelectric couple; a waste gas exhausting hole at the top part of the treatment chamber main cabin is provided with a waste gas purifying device which is used for purifying waste gas from a treatment chamber and then the purified waste gas is exhausted outwards; an air inlet device comprises a fan and an air inlet pipeline; the air inlet pipeline is provided with an air inlet flow valve. The large air pyrolysis treatment device disclosed by the invention has the advantages that the placement of garbage materials can be finished under the condition of relative isolation of the working environment of the treatment chamber main cabin by virtue of the isolating cabin, and thus outward leakage of odor and heat is prevented when the garbage enters; due to the garbage material transporting channel which is formed by the plurality of layers of transporting belts and realizes zigzag reciprocating circulation, full pyrolytic reaction can be carried out on the garbage materials in the treatment chamber; energy is greatly saved and the pyrolytic efficiency is greatly improved.

Description

technical field [0001] The invention relates to a garbage treatment device, in particular to a garbage pyrolysis treatment device. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, more and more garbage is generated in daily life and in the production and operation of various industries, and it contains a lot of organic waste that is difficult to degrade, which is constantly becoming an environmental hazard. At the same time, people are paying more and more attention to the world environment. How to maintain a green living environment has become a major issue in the development of the world. Among them, the large amount of domestic garbage produced every day in our growing and expanding cities is also an important part of waste treatment. The most important thing is to deal with a large amount of municipal solid waste that is continuously produced in a reasonable and environmentally friendly way, wh...

Problems solved by technology

However, there are still many problems in the direct incineration of garbage, such as: (1) Secondary pollution; acid gases (HCl, HF, NOx, etc.) Substances) and fly ash containing Hg and Pb will pollute the environment

(2) Damage to incineration equipment; chlorine-containing compounds in garbage form corrosive gases such as HCl in the furnace, which will seriously corrode metal parts in the furnace above 300 °C

(3) The composition of garbage is complex, and various components have different densities, shapes, chemical properties, ignition and combustion characteristics. They present different combustion properties in the incinerator, so it is difficult to control the combustion process

Although waste pyrolysis treatment devices have been used, there is no large-scale air pyrolysis treatment device that can centrally process a large amount of municipal solid waste, which obviously cannot keep up with the current rapid development of urban environment, urban culture, and increasingly colorful of city life
