Title:
DETOXIFICATION AND RECYCLING METHOD FOR GASIFICATION AND HIGH-TEMPERATURE MELTING OF FULL-INDUSTRIAL ORGANIC HAZARDOUS WASTE
Document Type and Number:
WIPO Patent Application WO/2023/109034
Kind Code:
A1
Abstract:
Provided are a detoxification and recycling method for gasification and high-temperature melting of full-industrial organic hazardous waste, comprising: multiphase pretreatment, multi-element regulation and control, and multi-component homogenization are performed on the full-industrial organic hazardous waste for furnace-entering raw material configuration, and flowing type raw materials subjected to precise compatibility and meeting related requirements undergo gasification and high-temperature melting reactions in a furnace, and then are subjected to chilling; generated gas is subjected to desulfurization, decarburization and purification to obtain carbon dioxide and high-purity hydrogen products, and glassy byproducts after chilling can be used as general solid waste after being subjected to hazardous waste identification; after sedimentation and filter pressing of chilled water, ash forms a filter cake, wastewater is recycled, and inorganic salt and nitrogen and phosphorus resources in the wastewater are extracted. Main elements in the furnace-entering raw materials are accurately regulated and controlled, gasification and high-temperature melting serve as reaction conditions, and element migration and transformation rules serve as a basis, thereby realizing detoxification and recycling of industrial organic hazardous waste, and near-zero emission of pollutants. The method is a low-carbon green and clean technical method.
