Background
At present, the annual output of domestic garbage reaches 10 hundred million tons, wherein the domestic garbage is about 4 hundred million tons, and the stock of Chinese garbage exceeds 80 hundred million tons. The data indicate that: more than two thirds of cities in China are surrounded by garbage, and one quarter of cities have no suitable places for stacking garbage, and the accumulated garbage stacking occupies 80 ten thousand mu of land area. The domestic garbage produced by 4 ten thousand villages and towns in China and nearly 60 ten thousand administrative villages per year exceeds 2.8 hundred million tons, and in most rural areas and small and medium towns, a great deal of garbage throwing and misplacement behaviors exist, so that the garbage throwing and misplacement behavior not only occupies scarce land and pollutes the environment, but also seriously endangers the health of human beings.
The treatment of Chinese garbage is still mainly landfill, and the landfill method is simple and extensive, and only the contaminated land is transferred. The volume of the garbage is generally reduced by 80% -90% after modern incineration treatment, meanwhile, various pathogens can be eliminated, harmful substances are converted into harmless substances, recycling utilization can be realized, and garbage incineration is one of main ways for realizing garbage reduction, harmless and recycling treatment.
Refuse incineration is one of the main ways of current refuse disposal, and the existing refuse incineration in China adopts a mechanical refuse incinerator, for example, CN104613481a discloses a refuse incinerator, and the refuse incinerator is provided in a transverse arrangement and is formed by combining a plurality of mobile units in the transverse direction, wherein the plurality of mobile units are integrally supported by a supporting device and are driven by the same driving device.
