Abstract

The invention discloses organic hazardous waste thermocatalytic efficient reduction double-kettle process equipment. The equipment is characterized by comprising a batching kettle with a material inlet connected to an organic waste feeding system, the batching kettle is connected to a first main reaction kettle and a second main reaction kettle respectively, the first main reaction kettle and thesecond main reaction kettle are connected to a cooling kettle, and the cooling kettle is connected to a solid-liquid separation system; the first main reaction kettle and the second main reaction kettle are connected to a steam system; the first main reaction kettle is connected to the batching kettle and the second main reaction kettle; the second main reaction kettle is connected to the batchingkettle and the first main reaction kettle; the cooling kettle is connected to the batching kettle, and the batching kettle is connected to a VOCs treatment system; and a cooling water pipeline of thecooling kettle and the batching kettle are communicated to form a cooling water circulation system. Hot steam is recycled through flash evaporation between the double-kettle equipment, energy is greatly saved, a catalyst is recycled after water treatment, and use of the catalyst is reduced; and a carbon crystallization product obtained by the reaction can be recycled, so that secondary pollutionto the environment is avoided.

Description

technical field [0001] The invention belongs to the technical field of organic waste treatment, and in particular relates to a double-pot process equipment for thermally catalytic and efficient weight reduction of organic hazardous waste. Background technique [0002] Hazardous wastes refer to those listed in the national list of hazardous wastes or recognized according to the identification standards and identification methods of hazardous wastes stipulated by the state, having one or more hazardous characteristics such as corrosiveness, toxicity, flammability, reactivity, and infectivity, and Solid wastes with the above hazardous characteristics are not excluded. (Ministry of Environmental Protection. GB5085.7—2007 Hazardous Waste Identification Standards [S]. Beijing: China Environmental Science Press, 2007.) [0003] In environmental pollution, organic hazardous waste has the greatest pollution impact, but its disposal is basically blank. Although the traditional incin...
