The pyrolysis reactor is the key for realizing thermochemical conversion, and the biomass pyrolysis carbonization device commonly used at present mainly comprises a fixed bed, a fluidized bed, a spiral pyrolysis reactor and other types.
The structural form and technological parameters of the pyrolysis device have important influence on the physicochemical structure, fuel property and other qualities of the pyrolytic carbon product. For example, the fixed bed device has simple structure, but lower heat transfer efficiency, and poor quality uniformity of pyrolytic carbon products caused by uneven heating of materials in the carbonization process, and belongs to intermittent production. The spiral pyrolysis reaction device can realize continuous production, but the expansion and contraction of the screw shaft at high temperature easily causes the reduction of the sealing property of the device, and in order to ensure pyrolysis residence time, the spiral pyrolysis reactor is used for improving the quality uniformity of pyrolytic carbon products, and a lengthened screw shaft is adopted, so that the screw shaft is easily deformed at high temperature, and the materials are blocked and cannot be conveyed normally. In addition, the condensable pyrolysis gas in the biomass pyrolysis carbonization process is easy to be adsorbed by the biochar, so that the use of the pyrolysis carbon in the specific field is limited, and if the requirements of the carbon heating type cigarette on the carbon heating body material can not be met.
In summary, in order to continuously and stably obtain a high-quality pyrolytic carbon product with stable and uniform quality, high purity and no adsorbed tar on the surface, it is necessary to develop a high-quality pyrolytic carbon production device which is continuously and stably operated and can regulate and control the surface structural characteristics of biomass pyrolytic carbon.
