Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0045] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0046] Such as figure 1 Shown, a kind of environmental protection and energy-saving garbage disposal method comprises the following steps:

[0047] Step 1: Preliminary high-temperature shrinkage treatment is performed on the bagged garbage through high-temperature treatment equipment, and then the bagged garbage treated by high-temperature shrinkage is transported to the screen in the drainage pool 10 for extrusion cutting and bag breaking treatment, and the bag is broken through the screen vibration Drain for at least 30 minutes;

[0048] Step 2: Hammer and crush the waste aft...

Abstract

The invention relates to the technical field of resource recycling, in particular to an environment-friendly and energy-saving garbage treatment method. The method comprises the following steps that bagged garbage is subjected to primary high-temperature shrinkage treatment and then is conveyed into a draining tank to be subjected to extruding cutting bag breaking and screen vibrating draining treatment; then the garbage is subjected to hammering crushing treatment by a crushing device I to screen out the relatively heavy garbage and the relatively light garbage; the relatively heavy garbage is subjected to hammering crushing by a crushing device II to screen out ferromagnetic substances for recycling and non-ferromagnetic substances, and the non-ferromagnetic substances are screened to obtain the tough garbage, the brittle garbage and the rigid garbage; the relatively light garbage and the tough garbage are combined, and then the dry tough garbage and the wet tough garbage are separated out; the dry tough garbage is subjected to incineration treatment; the wet tough garbage is used for preparing organic fermented fertilizers; and the rigid garbage and the brittle garbage are usedfor being fired into building bricks. According to the method, the harmless treatment on the garbage is achieved, no pollution is caused to the environment in the whole process, and a sustainable circulation system is achieved.

Description

technical field [0001] The invention relates to the technical field of resource recycling, in particular to an environmentally friendly and energy-saving garbage disposal method. Background technique [0002] In recent years, with the continuous development of major cities, the amount of domestic waste generated by urban residents has continued to increase. The average annual growth rate of garbage in the world is 8.42%, while the growth rate of garbage in China has reached more than 10%. The world produces about 500 million tons of waste every year, among which, China produces nearly 150 million tons of urban waste every year. Many cities in the world are facing the embarrassing situation of garbage siege. [0003] Municipal waste can generally be divided into four categories: recyclable waste, kitchen waste, hazardous waste and other waste. There are three traditional disposal methods for urban waste: landfill, composting and incineration. Both landfill and composting n...
