Description

The device of superheated steam continuous anaerobic carbonization organic waste
Technical field
The present invention relates to organic waste processing arrangements technical field, it is a kind of overheated to especially relate to The device of steam continuous anaerobic carbonization organic waste.
Background technology
At present, China's carbonization technical merit is the most single, is used for the carbonization of living beings, such as wood The organic carbonizations such as material, stalk, rice husk, coal.The carbonization effect requirements of carbide is the highest. Along with the fast development of the industries such as China Chemical Industry, agricultural chemicals, medicine, the substantial amounts of danger of annual generation Organic waste, a lot of discarded objects no doubt can destroy the pollution of difficult degradation by simple burning Thing, but substantial amounts of severe toxicity gas two English and residue, flying dust the like waste can be produced simultaneously.
The whole world produces organic waste more than 1,000,000,000 tons every year, China's dangerous waste in 2015 The raw amount of produce surpasses 60,000,000 tons, ends the whole nation in 2011 and holds danger wastes business licence Unit about 1500, danger wastes year disposal amount also can only be located more than more than 9,000,000 tons Putting ability and disposal technology can not meet far away present situation, incineration technology can not be disposed completely simultaneously All of danger wastes.The such as burning of high salt organic waste, can shorten making of incinerator Use the life-span.Therefore, the disposal industry of organic waste is badly in need of introducing more new technology.
