Problems solved by technology

At the same time, it was found that the composition of the tar produced by garbage pyrolysis is also extremely complex. The composition analysis found that the tar contains hundreds of kinds of substances, including various organic acids, phenols, ketones, aldehydes, PAHs, etc., among which chlorine and heavy metal elements are common. On the high side, the water content is about 20%, and the calorific value is about 13-18MJ / Kg. At the same time, the high content of sulfides causes foul odor, and it is difficult to comprehensively utilize
Many factors make it difficult for my country to make major breakthroughs in waste pyrolysis
[0005] Therefore, the existing waste pyrolysis equipment needs to be improved

Abstract

The invention discloses an organic garbage pyrolysis system and a method for treating organic garbage by using the organic garbage pyrolysis system.The organic garbage pyrolysis system comprises a pyrolysis reactor and a flue gas cleaner.The organic pyrolysis reaction system pyrolyzes organic garbage by using a pyrolysis reactor, the pyrolysis reactor is provided with a stirring assembly, so that materials are distributed evenly in the reactor and are fully pyrolyzed, oil gas generated by pyrolysis can be released quickly, secondary splitting of the oil gas can be suppressed effectively, and pyrolysis tar yield is improved.In addition, a heat accumulating type radiant tube serves as a heating source of the pyrolysis reactor, and a heat carrier does not exist.Meanwhile, after being purified, smoke generated by pyrolysis treatment can be discharged directly.The organic pyrolysis reaction system has the advantages of few equipment, simple structure, easiness in operation, low failure rate and the like.

Description

technical field [0001] The invention relates to an organic waste pyrolysis system and a method for treating organic waste by utilizing the aforementioned organic waste pyrolysis system. Background technique [0002] With the acceleration of my country's modernization process, municipal solid waste has become an important factor restricting the rapid development of green cities. At present, urban waste treatment methods in various countries in the world mainly include sanitary landfill, incineration, composting, pyrolysis, and comprehensive waste treatment. However, my country's related waste classification and waste comprehensive utilization technologies lag behind. At present, the main treatment method of waste is sanitary landfill, supplemented by incineration and composting. Moreover, with the advancement of science and technology and the enhancement of environmental protection awareness, people have increasingly recognized the destructive effects of "incineration" and "...
