Rotary household garbage low-temperature pyrolyzing furnace

Abstract

The invention provides a rotary household garbage low-temperature pyrolyzing furnace. A pyrolyzing furnace body of the pyrolyzing furnace is provided with a garbage feed port and a smoke outlet. The upper end of an ash hopper is connected to a bottom plate of the pyrolyzing furnace body. The lower end of the ash hopper is connected with an automatic ash discharge plate valve. The automatic ash discharge plate valve is connected with the bottom end of the ash hopper. A bottom plate of a pyrolyzing cone is welded and fixed to an axial upper circular ring of a bearing rotary disk. A stirring device is fixedly connected to the outer surface of the pyrolyzing cone. An air distribution device is fixedly connected to the pyrolyzing cone. The axial upper circular ring of the bearing rotary disk iswelded and fixed to a bottom circular ring of the pyrolyzing cone. An axial lower circular ring of the bearing rotary disk is welded and fixed to the bottom plate of the pyrolyzing furnace body. A driving device is matched with a radial gear ring of the bearing rotary disk. Ash scraping plates are fixedly connected to the outer surface of the pyrolyzing cone. Lifting lugs are firmly welded to thepyrolyzing furnace body. An air valve is fixed to the lower surface of a middle bottom plate of the pyrolyzing furnace body. A probe of a furnace body thermometer extends into a cavity. The pyrolyzing furnace has the advantages that a garbage layer in the furnace is adjustable, garbage is pyrolyzed uniformly, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to a rotatable low-temperature pyrolysis furnace for household garbage suitable for processing household garbage in rural areas and towns. Background technique [0002] Rural and township domestic waste treatment technologies mainly include three categories: sanitary landfill method, bio-effective composting method, and incineration power generation method; sanitary landfill method is a relatively traditional treatment method, which is easy to operate, but there are difficulties in site selection, It occupies a large area, has the disadvantages of odor pollution, leachate is difficult to handle, etc., and there is a risk of explosion caused by methane accumulation and leachate seepage polluting ground water; bio-effective composting generally accounts for a small proportion in foreign countries at present, because Compared with the landfill method, the investment is relatively high, the scale is limited, the quality is difficult t...

[0002] Rural and township domestic waste treatment technologies mainly include three categories: sanitary landfill method, bio-effective composting method, and incineration power generation method; sanitary landfill method is a relatively traditional treatment method, which is easy to operate, but there are difficulties in site selection, It occupies a large area, has the disadvantages of odor pollution, leachate is difficult to handle, etc., and there is a risk of explosion caused by methane accumulation and leachate seepage polluting ground water; bio-effective composting generally accounts for a small proportion in foreign countries at present, because Compared with the landfill method, the investment is relatively high, the scale is limited, the quality is difficult to control, and the product sales cannot be guaranteed, so the composting method can only be used as an auxiliary means of waste disposal

In the case of increasingly tight land resources, the waste incineration power generation treatment method is gradually being adopted by more and more countries. The technology is mature and can recycle el
