Description

Technical Field

[0001] The present invention relates to the technical field of biomass carbonization, and in particular to a biomass carbonization method, system, equipment and storage medium. Background Art

[0002] With the continuous growth of global energy demand and the increasing depletion of fossil energy, reducing dependence on fossil energy and developing and utilizing renewable energy have become global energy development trends. Biomass feedstocks, such as straw and wood chips, are renewable resources with high yields, widespread availability, low costs, and environmental friendliness. They are often used to partially replace coal in thermal power plants for biomass co-firing. Leveraging the renewability and low-carbon nature of biomass fuels, this fuel achieves a low-carbon transition for thermal power plants, while also improving energy efficiency and reducing fossil energy consumption and pollutant emissions. However, the combustion process of biomass feedstocks is unstable and prone to incomplete combustion, resulting in energy waste and increased pollutant emissions. This is because biomass feedstocks have a high volatile content and a fast combustion rate, but a short combustion duration. They are also prone to forming localized high and low temperature zones during combustion, which affects combustion uniformity. Therefore, biomass co-firing requires pulverization, drying, and carbonization. Carbonization improves the combustion characteristics of biomass. Carbonized biochar has a more regular pore structure and a higher specific surface area, which facilitates oxygen diffusion and combustion reactions. At the same time, biochar burns relatively slowly and lasts longer, which can better match the combustion process with fuels such as coal and improve the overall combustion efficiency of the boiler.

[0003] The existing biomass carbonization process relies on manual experience. This method of controlling biomass carbonization is often difficult to ensure consistent quality of the carbonized product due to the subjectivity and uncertainty of manual experience, as well as differences in judgment and operational skills among different operators. This lack of precise judgment standards also makes it difficult to ensure consistent quality of the carbonized product. Furthermore, the moisture content, particle size, and composition of the biomass feedstock significantly impact the carbonization process. When material properties change rapidly, such as a sudden increase in moisture content, manual operation is unable to immediately detect and respond to material changes, making it impossible to accurately adjust process parameters, leading to quality issues in the carbonized product.

[0004] Furthermore, the carbonization process, which relies on manual experience, requires operators to monitor and adjust the equipment for extended periods of time, resulting in high labor intensity and a high risk of fatigue. This not only affects the operator's health but can also lead to operational errors, reducing production efficiency and product quality. Due to the limitations of manual operation, the heating and cooling stages of the carbonization process often take a long time, extending the production cycle and further reducing production efficiency. Summary of the Invention

[0021] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a biomass carbonization method, which obtains biomass carbonization data in real time; and adjusts the inclination angle of a drying tube and the flue gas flow rate according to the biomass carbonization data, so that the biomass is uniformly carbonized, thereby achieving real-time adjustment of the biomass carbonization process. By obtaining key biomass carbonization data such as the moisture content of biomass particles, the functional group ratio of biomass carbonization products, and the oxygen concentration in the drying tube in real time, the method can comprehensively and accurately grasp various key parameters in the biomass carbonization process. These parameters provide an accurate basis for subsequent adjustment operations, and the inclination angle of the drying tube and the flue gas flow rate are specifically adjusted according to the various parameters to adjust the residence time of biochar in the drying tube and the flue gas flow rate, optimize the carbonization conditions, and accurately control the degree of the carbonization reaction, thereby achieving uniform carbonization of the biomass.

[0022] The adjusted inclination angle of the drying tube and the flue gas flow rate are calculated based on the moisture content of the biomass particles, the functional group ratio of the biomass carbonization product, and the oxygen concentration in the drying tube. The moisture content of biomass particles in different batches may vary. When the moisture content is high, by calculating and adjusting the inclination angle of the drying tube, the residence time of the material in the drying tube can be extended, ensuring that the moisture is fully evaporated, and avoiding uneven carbonization or burning due to residual moisture; the functional group ratio of the biomass carbonization product reflects the degree of carbonization and product characteristics. By comprehensively calculating the inclination angle of the drying tube, it can ensure that the biomass has sufficient reaction time while improving the degree of precise control of the carbonization process and further improving the consistency of the carbonized product. The oxygen concentration in the drying tube is an indicator to ensure the carbonization process and safe carbonization. Incorporating the oxygen concentration factor into the calculation of the inclination of the drying tube can not only control the oxygen concentration within a safe range, but also adjust the contact between oxygen and biomass, improving carbonization uniformity while ensuring production safety.

[0023] It also includes obtaining the crushed particle size of the biomass and adjusting the knife roller frequency and screen aperture according to the crushed particle size of the biomass. The physical properties of different biomass raw materials vary greatly, and different application scenarios have specific requirements for the biomass crushed particle size. By obtaining the biomass crushed particle size, it is possible to understand in real time whether the current crushing effect meets the standard. During the crushing process, the physical properties of the biomass may change. For example, as the crushing proceeds, the hardness of the biomass may decrease. By obtaining the crushed particle size, these changes can be discovered in time, and the knife roller frequency and screen aperture can be adjusted accordingly to achieve precise control of the biomass particle size and reduce rework and repeated crushing.

[0024] The present invention also provides a biomass carbonization system, comprising a control unit and a crushing unit and a drying and carbonizing unit connected in sequence to a biomass material output end; wherein the moisture content detection device of the crushing unit can obtain the moisture content of the biomass particles in real time. The control unit can adjust the operating parameters of the crushing unit and the carbonization unit based on the moisture content data. At the same time, in the drying and carbonizing unit, the functional group ratio monitoring device of the biomass carbonization product can monitor the functional group ratio in real time, adjust the inclination angle of the drying tube and the flue gas flow rate according to the moisture content, and adjust the inclination angle of the drying tube and the flue gas flow rate during the carbonization process based on the parameter data obtained by the crushing unit and the carbonization unit, ensuring that the biomass is carbonized under appropriate conditions, avoiding uneven carbonization due to moisture problems, and improving the consistency of product quality. The control unit highly integrates a data acquisition module and a biomass carbonization control module, wherein the data acquisition module is responsible for real-time acquisition of biomass carbonization data; the biomass carbonization control module is responsible for adjusting the inclination angle of the drying tube and the flue gas flow rate based on the biomass carbonization data to ensure uniform carbonization of the biomass, thereby achieving real-time automated adjustment of the biomass carbonization process and ensuring the uniformity and consistency of carbonization.
