Background
Garbage is a renewable resource, and if the garbage can be effectively utilized in an integrated way, huge economic benefits can be created. The existing landfill mode can treat garbage, but has the problems of consuming land resources, polluting soil water bodies and the like. Yet another common treatment is incineration. However, since the garbage generally has the problems of high humidity, complex components and the like, the common incineration treatment mode is not easy to completely burn, toxic and harmful gases (dust, sulfur-containing, nitrate pollutants, dioxin and the like) are easy to generate, and in order to enable the garbage to be ignited, fuel is also required to be added, so that extra energy consumption and pollutant generation are caused. The garbage pyrolysis gas is a process of utilizing the thermal instability of organic matters in garbage, heating and distilling the garbage to crack the organic matters, condensing the organic matters to form various new gases, liquids and solids, and extracting combustible gas from the gases.
However, the existing garbage pyrolysis furnace generally has the defects that the garbage treatment capacity cannot be high because of insufficient pyrolysis caused by excessive coming and accumulation in the furnace, so that the garbage needs to be subjected to batch pyrolysis mechanically, a large amount of manual servo is needed during the batch pyrolysis, and the heat energy is easily lost due to the frequent charging of the furnace.
