Abstract

The invention discloses a method and equipment for fluidized bed gasification and melting treatment of solid waste and hazardous waste. The equipment comprises a shredder, wherein a discharge port ofthe shredder is connected to a conveyor, a discharge port of the conveyor is communicated with a feed port of a stokehole stock bin, and the stokehole stock bin is connected to a fluidized bed gasification furnace through a sealed feeder; an exhaust port of the fluidized bed gasification furnace is connected to a separator and a melting furnace, and an ash discharge port of the separator is communicated with a return feeder; an ash discharge port of the return feeder is connected to the fluidized bed gasification furnace; and a slag hole of a melting fire grate is connected to a water quenching slag box. According to the method, the solid waste and the hazardous waste are subjected to gasification reaction firstly, organic matter and carbon in the solid waste and the hazardous waste are changed into combustible gas, and ash fusion is achieved through the characteristics that gas-gas reaction is violent and high temperature is likely to be generated. Only furnace slag and vitreous bodies which are burnt at high temperature are generated in the whole process, so that harmless treatment of the solid waste and the hazardous waste is realized.

Description

technical field [0001] The invention belongs to the field of urban and industrial solid and hazardous waste disposal, and in particular relates to a method and equipment for treating solid and hazardous waste by fluidized bed gasification and melting. Background technique [0002] With the proposal of the goal of "zero waste city", the construction index system centered on the reduction of solid waste and recycling rate will be gradually established and improved. At the same time, the green development index system and the ecological civilization construction target system will also be integrated. With the establishment and optimization of various index systems, the solid waste treatment industry will become more standardized. [0003] Hazardous waste treatment is very important for building a "waste-free city". According to the latest "National Hazardous Waste List" jointly promulgated by the Ministry of Environmental Protection and the National Development and Reform Comm...
