A kind of efficiently short cracking dual firing chamber rubbish thermal cracking heat energy reburner
Technical field
The invention belongs to field of garbage disposal, be specially a kind of efficiently short cracking dual firing chamber rubbish thermal cracking heat energy reburner.
Background technology
Along with the quickening of economic development and urbanization, the quantity that annual domestic waste produces is multiplied. The traditional approach of garbage disposal is to build refuse landfill, is filled by rubbish. There is many drawbacks in this mode, first takies a large amount of soil exactly to build landfill yard, and soil is non-renewable resource, and land resource is pretty nervous; Second, after the material such as large amount of organic and battery enters landfill yard, the poisonous percolate of its generation will bring severe contamination to soil and groundwater, consider from the angle of environmental protection, have to set up that percolate from garbage filling field is impermeable, collection processing system implementing, this difficulty that will develop skill, also increases investment simultaneously, fills complicated operation, manage also highly difficult, additionally, the waste gas such as the methane of landfill yard, hydrogen sulfide also must be handled well, to guarantee explosion-proof and environmental requirement; Its three, a large amount of dumpings are in landfill yard, and the matter and energy wherein contained cannot be obtained by, and according to the viewpoint of recycling economy, this is also a kind of wasting of resources. Because landfill has such drawback, seldom adopt in this simple process mode of developed country at present.
, when thermal cracking rubbish, burning insufficient in existing combustion furnace, it is easy to produces bigger smoke pollution, bring difficulty to subsequent treatment; And the thermal conversion efficiency of pyrocrack furnace is low, waste heat waste is many, causes bigger pollution and waste. There is the space of bigger improvement in existing crucible garbage cracking.
