Technical field
The present invention relates to the refuse disposal for being sorted after technical field of waste treatment, more particularly to a kind of high-temperature heat treatment again and
Application process.
Background technology
As resource is nervous and environmental degradation, refuse classification is increasingly taken seriously, and refuse classification is a system engineering,
Including putting on by classification, receive the links such as fortune, process.China in 20th century mid-term Beijing carry out separate waste collection pilot work,
Hereafter promulgate in succession《Urban garbage disposal and prevention and cure of pollution policy》、《Domestic rubbish disposal guide》Life is advocated energetically
Separate waste collection and transport, disposal.And issue at the beginning of 21 century《Experimental city is collected with regard to announcing categorized consumer waste
Notify》8 cities such as selected Beijing, Shanghai, Guangzhou, Nanjing, Shenzhen are used as separate waste collection experimental city.
But limited by the factors such as domestic waste transport, disposal technology means and condition, categorized consumer waste is received
Collection, process work progress are slow, and effect is unsatisfactory.At present, China's majority cities, especially the life rubbish of small and medium-sized cities
Rubbish is still in mixed collection and the state of mixed processing.Therefore, rubbish is classified from source and is difficult at present meet China pair
House refuse carries out the demand of classified use.
In the prior art, main method is that first rubbish is carried out to carry out heat after artificial or mechanical means is sorted
Process, the major defect of this method is：Sorting is carried out before rubbish heat treatment and is also easy to produce stench, make severe operational environment；And
Sorting is carried out before rubbish heat treatment and is also easy to produce percolate, cause secondary pollution；Additionally, artificial separation causes human cost to increase；
Therefore, the above-mentioned technological deficiency for how overcoming traditional rubbish heat treatment method is that those skilled in the art are badly in need of solving
