Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a biomass hydrothermal charcoal generation reaction kettle. Background Art

[0002] Hot charcoal is a black solid product mainly composed of carbon and rich in oxygen functional groups, which is obtained by hydrothermal reaction at 150℃-375℃ and autogenous pressure with biomass or its components as raw materials and water as solvent and reaction medium.

[0003] For example, the double-axis hydrothermal carbonization reactor with patent number CN220224107U includes a reactor body and a horizontal axis stirring component and a vertical axis stirring component inside the reactor body. The horizontal axis stirring component is arranged at the bottom of the reactor body, and the vertical axis stirring component is arranged at the upper part of the reactor body; a feed port is arranged at the bottom of the reactor body, and a discharge port is arranged at the top; a circulation pipeline is arranged between the feed port and the discharge port of the reactor body, so that part of the biochar slurry discharged from the reactor body can be returned to the bottom of the reactor body. The above documents still have deficiencies. When in use, the viscosity is large, the fluidity is poor, Materials with high resistance enter from the bottom of the kettle and are stirred by the horizontal axis stirring assembly. As the hydrothermal carbonization reaction proceeds, the viscosity of the material decreases, the fluidity increases, and the resistance decreases. The vertical axis stirring assembly stirs to complete the hydrothermal carbonization reaction. It is suitable for hydrothermal carbonization of high-solid and high-viscosity organic solid waste. The combination of horizontal axis stirring and vertical axis stirring can improve the uniformity of material stirring in the kettle, make the temperature more uniform, increase the processing capacity, and increase the reaction efficiency. However, when performing hydrothermal carbonization reaction on biomass, it is not convenient to control the amount of biomass added. At the same time, after the reaction of the biomass is completed, impurities are attached to the inner wall of the reactor, and it is not convenient to clean the inner wall of the reactor after the reaction is completed.
