Destructive distillation method and device for organic solid waste harmless treatment

Abstract

The invention relates to a destructive distillation method and device for organic solid waste harmless treatment. Drying is conducted through sending organic solid waste into a drying room arranged horizontally, and then destructive distillation is conducted through pushing the organic solid waste into a sealed destructive distillation room arranged horizontally, continuous stirring on materials is conducted in the destructive distillation process, full drying and destructive distillation are conducted on the materials, and the destructive distillation efficiency is high; solid pyrolysate formed by destructive distillation is mainly coke which can be utilized, dry distillation gas generated by destructive distillation is the gas with a high heating value, part of the solid pyrolysate and the dry distillation gas can be burned to obtain the heat source of the drying and destructive distillation, and the restof the solid pyrolysate and the dry distillation gas can be collected and stored. According to the destructive distillation method and device for the organic solid waste harmless treatment, the organic solid waste harmless treatment is achieved, the energy is saved, and the clean energy which is utilized in high degree can be produced through the destructive distillation.

Description

technical field [0001] The invention relates to a dry distillation method and dry distillation equipment, in particular to a dry distillation method and dry distillation device for harmless treatment of organic solid waste. Background technique [0002] One of the ways to harmlessly treat the organic solid waste in municipal solid waste is to dry it. Dry distillation refers to the process in which organic solid waste is decomposed from high-molecular organic compounds into low-molecular carbohydrates by heating in the absence of gasification agents such as oxygen, air, carbon dioxide, and water vapor, resulting in an increase in entropy. The dry distillation of solid waste is affected by factors such as the chemical composition of solid waste, moisture content, the type of reactor and its operation mode, dry distillation temperature and reaction time. Studies have shown that when the temperature reaches 200°C, solid waste dries due to its physical separation of moisture. W...

Problems solved by technology

[0008] (2) High energy consumption

The above-mentioned device generates high-temperature gas through the gasification section to provide the heat source required for dry distillation and drying, but the gasification reaction is an endothermic reaction that consumes a lot of energy, so the energy consumption is relatively high

[0009] (3) The high-temperature hot gas directly leads to the drying chamber and the carbonization chamber, and the temperature cannot be controlled, so it is impossible to control the carbonization process to produce the required carbonization products

[0010] (4) After the material enters the retort chamber, it accumulates in the retort chamber and is heated unevenly, which affects the retort efficiency
