Description

TECHNICAL FIELD

[0001] The present application relates to carbonization furnace technology, in particular to a segmented biomass continuous drying pyrolysis carbonization equipment. BACKGROUND

[0002] Biomass carbonization is a process that converts biomass (such as straw, wood) into biochar, pyrolysis gas and bio-oil under oxygen-deficient or limited oxygen conditions. This process is achieved through pyrolysis technology, in which biomass undergoes drying, pyrolysis and other stages at temperatures ranging from 350°C to 650°C, and large molecular organic matter is gradually decomposed into small molecular volatile matter, while forming carbon-rich solid biochar. Biomass carbonization technology is diverse, including pyrolysis carbonization, hydrothermal carbonization and microwave pyrolysis, each with its unique advantages and application scenarios.

[0003] Biomass carbonization has multiple values. In the agricultural field, biochar as a soil conditioner can significantly improve soil fertility and crop yield, while adsorbing heavy metals in the soil and reducing crop absorption of heavy metals. In the energy field, the combustible gas and bio-oil produced during the carbonization process can be used as clean energy to replace traditional fossil energy and serve power generation or heating. In addition, biomass carbonization technology is also widely used in sludge treatment, industrial waste conversion and other fields, realizing the recycling of resources and protection of the environment.

[0004] Biomass carbonization equipment is the key, among which biomass carbonization furnace can be divided into batch processing and continuous type. Continuous biomass carbonization furnace has the characteristics of high production efficiency and high automation, suitable for large-scale production, and can meet the demand of different fields for biochar. With the progress of technology, biomass carbonization furnace is increasingly widely used in the fields of energy recovery, environmental protection, agricultural waste treatment and other fields, contributing to sustainable development.

[0005] The existing pyrolysis carbonization equipment lacks the cooperation of the roller and the fixed ring when in use, which causes the carbonization furnace to easily deviate when rotating, affecting the running stability; the traditional equipment mostly uses the whole heating method, which leads to low pyrolysis efficiency or unstable quality of biochar; the material is unevenly heated, and due to the lack of spiral propulsion, the material is easy to accumulate or move unevenly in the furnace, causing local overheating or insufficient pyrolysis, and the biochar is directly discharged after being cold-made, resulting in high biochar discharge temperature and easy spontaneous combustion after discharge.
