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 disposal method, which comprises the following steps: after preliminary high-temperature shrinkage treatment of bagged garbage, it is transported to a drain tank for extrusion, cutting, bag breaking and screen vibration draining treatment, and then The relatively heavy garbage and relatively light garbage are screened out after hammering and crushing by the crushing device I; the relatively heavy garbage is hammered and crushed by the crushing device II, and then the ferromagnetic materials and non-ferromagnetic materials are screened out, and then the ferromagnetic materials are recovered. Non-ferromagnetic materials are screened to obtain ductile waste, brittle waste and rigid waste; the relatively light waste and ductile waste are combined to separate dry ductile waste and wet ductile waste; the dry ductile waste is incinerated; the wet ductile waste is incinerated; Tough waste is used to prepare organic fermented fertilizer; rigid waste and brittle waste are used for burning into building bricks. The method of the invention realizes the harmless treatment of garbage, does not cause pollution to the environment in the whole process, and realizes a sustainable circulation system.

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...
