Double-loop double-pyrogenation incinerator for garbage harmless treatment and its usage method

Abstract

The invention relates to double loop double pyrolysis incinerator and its using method. Its features are that drying apparatus is formed by horizontal rotary kiln drying device, steam separator, and fume reflux line; the feed port of the horizontal rotary kiln is connected with discharge port of the feeding device; its discharge port is connected with the feed port above secondary burning chamber. While running, part of high temperature fume of secondary burning chamber can enter the rotary kiln to process reverse drying preheat and pyrolysis for the garbage; cooled fume is inducted into the secondary burning chamber by secondary fan after dehydrating by steam separator. Compared with exiting technique, the invention has the advantages of continual heat transfer, fast gasification rate, full burning, processing domestic garbage without auxiliary fuel etc.

Description

Technical field: [0001] The invention relates to environmental protection equipment for the harmless treatment of garbage, in particular to a vertical pyrolysis incinerator with double-circuit drying and pyrolysis technology for the harmless treatment of garbage and its treatment and use method. Background technique: [0002] At present, domestic urban and rural domestic garbage centralized treatment methods mainly include sanitary landfill method, composting method, direct incineration method and comprehensive incineration treatment method. The disadvantages of the sanitary landfill method are: difficult site selection, large investment, inability to reduce waste, and difficult disposal of waste seepage. The composting method has played a certain role in dealing with a large amount of domestic waste and stale waste. However, there is still a certain gap between my country's composting technology and equipment compared with foreign developed countries, especially due to the ...

However, in the pyrolysis furnaces of the above two technologies, the primary garbage with high moisture content is allowed to enter the pyrolysis furnace directly from the upper inlet of the pyrolysis furnace through the feeding mechanism at room temperature, and then directly complete the process in the pyrolysis furnace body. During the drying and pyrolysis process of materials, since general garbage, especially domestic garbage, is stored in the open air and has a high moisture content, the effect of continuous pyrolysis and incineration is greatly affected and restricted from time to time, resulting in the effect of pyrolysis and the subsequent stage of elimination. The effect of smoke and dust removal and purification is still not ideal, and there are shortcomings that cannot be widely promoted and used
