The invention discloses a fluidized gasification and detoxification system of pre-concentrated salt slag, and belongs to the technical field of waste recycling. The system comprises a fluidized gasifier and a helical water cooler. The pre-concentrated salt slag enters the fluidized gasifier for gasification and detoxification firstly, is discharged from an overflow port and enters the helical water cooler for cooling, after water washing and filtration, a filtrate enters a crystallizing evaporator, and finally, a crystalloid salt product is formed. The invention further discloses a fluidized gasification and detoxification method of the pre-concentrated salt slag. The system and the method adopt the high-temperature organic matter gasification principle, heat is supplied by using high-temperature air, primary separation of organic matter from salt in the pre-concentrated salt slag is achieved in the fluidized gasifier under the conditions of high-temperature turbulence and an inert atmosphere the crystalloid salt formed through cooling, water washing, filtration and recrystallization can be used as a raw material of industrial salt in the chlor-alkali industry, and filter residuesand fly ash return to an incinerator for incineration; the fluidized gasification and detoxification system can be embedded into a hazardous waste incineration system, the treatment cost of the pre-concentrated salt slag is effectively reduced, and the problem that the crystalloid salt is contaminated by pollutants in flue gas is avoided.
Description
technical field [0001] The invention belongs to the technical field of waste resource utilization, and in particular relates to a pre-concentrated salt slag fluidized bed gasification detoxification system and method. Background technique [0002] Pre-concentrated salt slag is generally produced in the sections of high-salt waste liquid evaporation concentration and membrane separation in fine chemical industries such as pesticides and pharmaceuticals. It is a typical hazardous waste that is difficult to treat in the chemical industry. [0003] Thorough separation of organic matter and salt in pre-concentrated salt residue is the key to the ultimate realization of waste salt recycling. At present, the incineration method is mainly used to treat pre-concentrated salt residue at home and abroad. Incineration technology can use high temperature to completely decompose residual organic poisons in pre-concentrated salt residue , but because the operating temperature is too high, ...
