Container type garbage pyrolysis treatment device and method

Abstract

The invention discloses a container type garbage pyrolysis treatment device which comprises a container, a combined pyrolysis gasification furnace, a gas purifying tower, a quenching spray tower, an aeration purifying filtering tower, a high-pressure induced draft fan and an exhaust cylinder. The container is used for containing other parts. The combined pyrolysis gasification furnace comprises a garbage oxygen-free pyrolysis bin, an oxygen-deficient decomposition bin, a fusion chamber, a gas conversion bin, a water seal ash box, a heating chamber and a waste gas oxidation box. One end of the combined pyrolysis gasification furnace is provided with a continuous feeding sealing device. Gas produced after garbage is gasified through the combined pyrolysis gasification furnace returns to the heating chamber for combustion after acid gas and impurities are removed through the gas purifying tower, and provides heat energy for the garbage oxygen-free pyrolysis bin and the oxygen-deficient decomposition bin. Smoke generated due to combustion in the heating chamber enters the waste gas oxidation box for secondary heating oxidation, and the obtained waste gas enters the quenching spray tower for quick cooling through a smoke heating pipeline, then is introduced into the aeration purifying filtering tower by the high-pressure induced draft fan for filtering, and is exhausted to the atmosphere through the exhaust cylinder.

Description

technical field [0001] The invention relates to the field of garbage treatment devices, in particular to a carrying box type garbage pyrolysis treatment device and method. Background technique [0002] At present, my country's domestic waste treatment mainly includes sanitary landfill technology, composting (biochemical) technology and incineration technology. Most areas use sanitary landfill method to deal with domestic waste, which not only takes up a lot of land, wastes resources, but also easily pollutes land and groundwater; composting only utilizes about 40% of organic matter, and it is necessary to build supporting incineration process equipment and sanitary landfills. Heavy metals in composting products may pollute the soil and enter the food chain crops, and there are also secondary Hidden dangers of secondary pollution; the incineration method is used to deal with urban domestic waste, and the waste heat is used for power generation or heat supply, which can reduce t...
