Embodiment Construction
[0042] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0043] One of the core ideas of the embodiment of the present application is to remove chlorine from chlorine-containing plastics in household waste through two steps of primary treatment in a high-temperature and high-pressure autoclave fed with steam and secondary treatment in a drying kiln. element
[0044] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a domestic waste treatment method of the present application, wherein the domestic waste includes: chlorine-containing plastics, which may specifically include the following steps:
[0045] Step 101, putting the domestic garbage into the autoclave, and feeding steam into the autoclave;
[0046] Step 102, adjusting the t...

The embodiment of the invention provides a household garbage treatment method. Household garbage comprises chlorine-containing plastic. The household garbage treatment method comprises the steps that the household garbage is put into an autoclave, and steam is introduced into the autoclave; and the temperature and the pressure value of the autoclave are adjusted, and deodorization and virus killing treatment is conducted on the household garbage, specifically, virus killing and deodorization treatment comprises the steps that primary treatment is conducted on the chlorine-containing plastic, primary emissions discharged after primary treatment are collected, the household garbage subjected to virus killing and deodorization treatment is put into a drying cellar, the temperature of the drying cellar is adjusted, secondary treatment is conducted on the chlorine-containing plastic, and discharged secondary emissions after secondary treatment are collected. According to the household garbage treatment method, chlorine elements of the chlorine-containing plastic in the household garbage are removed through primary treatment conducted in the high-temperature and high-pressure autoclave and secondary treatment conducted in the drying cellar, and thus dioxin can be effectively reduced during subsequent incineration.
Description
technical field [0001] The present application relates to the technical field of garbage disposal, in particular to a domestic garbage disposal method and a domestic garbage disposal device. Background technique [0002] Household garbage is the waste produced by urban residents in their daily life. With the development of the urban process, domestic garbage is constantly being produced, which has reached the point where the city is surrounded by garbage, threatening environmental protection and safety, and seriously affecting people's normal life. [0003] There are two treatment methods for domestic waste: landfill and centralized incineration for power generation. Among them, garbage landfill is a serious waste of land resources. At present, 80% of the primary garbage in big cities adopts this incineration power generation technology. These primary wastes are incinerated to generate electricity without treatment. During the incineration process, chlorine-containing plast...
