Description

technical field

[0001] The invention relates to the field of garbage classification, in particular to a domestic garbage crushing and sorting system. Background technique

[0002] According to statistics, in 2014, the annual volume of municipal solid waste in my country was about 191 million tons, and it was growing at an annual rate of 8%-10%. . At present, my country's municipal solid waste treatment methods mainly include sanitary landfill, composting, and incineration. Among them, incineration has become a more popular treatment method because it can greatly reduce the volume and weight of garbage, and can generate clean electricity. However, the composition of domestic garbage in our country is complex, and the volume of garbage is different. In particular, it contains a large amount of kitchen waste, and it is mostly placed in plastic bags, making the moisture content of domestic garbage mostly above 50%, resulting in difficulty in burning garbage and low efficiency. ...
