Density Sorting Technology and Equipment for Domestic Garbage

Abstract

The invention relates to a domestic garbage density method sorting technology and device. The pretreatment technology adopted before domestic garbage enters a furnace is the worldwide problem so far,non-combustible matter accounting for 50% of domestic garbage participates in incineration, damage is caused to the society and enterprises, and people are afraid of garbage incineration or even resist garbage incineration. By means of the domestic garbage density method sorting technology and device, a sorting medium is configured based on the density method sorting principle, the density value of the sorting medium is located between the density value of non-combustible matter and the density value of combustible matter in domestic garbage, the domestic garbage enters a sorting bin, separation of the combustible matter and the non-combustible matter is rapidly completed in the sorting medium, the combustible matter is pressed and dried and then enters an incinerator to be incinerated ina dry matter state, the non-combustible matter is subjected to magnetic separation and smashing and then is used as a roadbed material, and the sorting medium flows back into a backflow purifying poolto be purified and then repeatedly used. The domestic garbage density method sorting technology and device have the beneficial effects of being reasonable in design, simple in structure, convenient to use and economically feasible, and harmless, reducing and resourceful treatment of domestic garbage is achieved indeed.

Description

technical field [0001] The invention relates to the field of household garbage treatment, in particular to a sorting process and equipment of household garbage by density method. Background technique [0002] The pretreatment technology of domestic waste before being incinerated is a worldwide problem so far. Although the incineration technology and equipment are constantly improving, due to the fact that the domestic waste entering the furnace has not been strictly sorted, a large amount of non-combustible substances and water accounting for about 40% of the total domestic waste participate in the incineration, resulting in high ash content, High harmful gas emissions, low production capacity and low economic benefits. These "two highs and two lows" have seriously polluted the environment, endangered human health, and the safety of livestock and poultry, and also made many people in the society fear and even openly resist the mention of thermal power plants that incinerate...

AI Technical Summary

Problems solved by technology

[0009] Japan's RDF research requires air separators, pulverizers, vibrating screens, etc. Due to the complexity of the process, the production capacity is restricted. The production capacity of the RDF device in Banwara Town, Nara City is only 28t / 7h, and it can only be collected as small domestic waste. Station use, unable to support large-scale thermal power enterprises
