Description

technical field

The invention relates to a treatment device for waste residue, and more specifically relates to a complete set of high-temperature anaerobic pyrolysis device for oil-containing hazardous waste.

Background technique

Among the hazardous wastes, there are many sludges, oil feet, residues, sludges, wastes, muds, etc. containing waste oils and liquids. Not only are there a large number of them, but they are also very difficult to deal with, and the treatment cost is high. In the past, oil-containing hazardous wastes were mainly treated by pressing, incineration, and landfill technologies. The oil content of pressing treatment is still high, and the oil content of incineration treatment is low, but the smoke and fly ash are large, secondary pollution is heavy, and oil resources are not available. Can be recycled; landfill treatment requires a large amount of land, pollutes the surrounding environment, and leaves major hidden dangers. At present, oily hazardous wastes are mainly treated by sealed rotary drying furnaces. A set of sealed rotary drying furnaces requires an investment of 1.5 million yuan to process 5 tons of oily hazardous wastes in three days, with an average treatment cost of 917.4 yuan/ton; The oil content is greater than 2%, which is much higher than the requirement of GB4284-2018 "Agricultural Sludge Pollutant Control Standards" that the oil content of dry residue is less than 3‰. It cannot be returned to cultivated land, and it is not allowed to be discharged directly, so it is difficult to be used as building materials. In order to improve the treatment technology level of oily hazardous waste, significantly reduce the oil content in the dry residue after oily hazardous waste treatment, significantly reduce the cost of oily hazardous waste treatment, significantly increase the processing speed, actively recycle waste oil, and save energy, a method needs to be explored. A complete set of high-temperature anaerobic pyrolysis equipment for oily hazardous waste.
