Embodiment 1

[0058] like figure 1 As shown, the present invention provides a kind of household garbage disposal method, comprises the following steps:

[0059] S101: Perform bag breaking, magnetic separation, and eddy current sorting on domestic waste to select magnetic substances and metal substances.

[0060] Firstly, pour domestic garbage into the garbage storage tank, and the apron feeder sends the domestic garbage into the bag breaking machine for bag breaking. The bag breaking machine is a flying shear bag breaking machine, which can quickly and evenly break the garbage bags Garbage is scattered out to facilitate subsequent screening work. The domestic waste after bag breaking enters the magnetic separator to select magnetic materials, such as: magnets, waste batteries, etc.; the domestic waste after magnetic separation is sorted by the eddy current machine to separate metal substances. For example: copper, aluminum, etc. Metals such as copper and aluminum will become catalysts for...

Embodiment 2

[0084] like image 3 As shown, the present invention also provides a domestic waste treatment device, which includes sequentially connected: bag breaking machine 1, magnetic separator 2, vortex machine 3, ball mill 4, dissolving filter 5, squeeze filter 6, dryer 7 , gasifier 8 and internal combustion engine 9; wherein,

[0085] The bag breaking machine 1 is used to break bags of domestic garbage, so that the garbage is scattered out;

[0086] The magnetic separator 2 is used for magnetically separating domestic garbage to select magnetic substances;

[0087] The vortex machine 3 is used for vortex sorting the domestic garbage to select metal substances;

[0088] The ball mill 4 is used for ball milling the domestic garbage after the magnetic substances and metal substances are selected to obtain powdery organic matter and granular inorganic matter;

[0089] The dissolving filter 5 is used for dissolving and filtering powdery organic matter and granular inorganic matter to o...

Abstract

The invention relates to the technical field of domestic garbage disposal, in particular to a domestic garbage treatment method and device. The domestic garbage treatment method includes the steps that domestic garbage is subjected to bag breaking, magnetic separating and vortex separating treatment so that magnetic substances and metal substances can be separated; the domestic garbage with the magnetic substances and the metal substances separated is subjected to ball-milling treatment, and powder-like organic matter and granular inorganic matter are acquired; the powder-like organic matter and the granular inorganic matter are subjected to dissolving and filtering treatment, and an organic matter solution is obtained; the organic matter solution is subjected to filter-pressing concentration treatment, and cake-shaped organic matter and waste water are acquired; the cake-shaped organic matter is subjected to drying treatment, and garbage derived fuel and waste gas are acquired; and the garbage derived fuel is subjected to pyrolysis gasification, and combustible gas is generated and used for power generation. According to the domestic garbage treatment method and device, the domestic garbage is subjected to multi-stage separation so that useful substances can be separated to be reused, the converting rate of resources is increased, and the treated garbage reaches the clean discharging standard.

Description

【Technical field】 [0001] The invention relates to the field of garbage treatment, in particular to a domestic garbage treatment method and device. 【Background technique】 [0002] With the development of the economy and the improvement of people's living standards, the output of domestic waste is also increasing. At present, domestic mainstream domestic waste disposal methods are landfill, incineration power generation and diversified treatment. The landfill method not only occupies a large amount of land resources, but also causes serious secondary pollution to the land and groundwater; due to the poor classification effect of domestic waste, the calorific value of the material used for incineration for power generation is too low, the power generation efficiency is low, and the dioxin produced by incineration Serious air pollution poses a threat to people's life and health; diversified treatment is to sort domestic waste and then process various items, but the existing sor...
