Problems solved by technology

[0005] However, the pyrolysis device in the above-mentioned patent does not control the volume of the waste, and does not classify the waste according to the volume of the waste after pyrolysis, resulting in a low uniformity of pyrolysis, which is not conducive to the secondary processing of biochar , and the pyrolysis adopts direct combustion pyrolysis with an open flame, which can easily lead to excessive pyrolysis and waste energy. At the same time, the pyrolysis process stays in the pyrolysis chamber of the device, and a driving device is required to discharge the biochar obtained after pyrolysis out of the device chamber. lead to low efficiency of pyrolysis

Description

technical field [0001] The invention relates to the technical field of pyrolysis processing devices, in particular to a pyrolysis processing device and processing method for preparing biochar for recycling waste materials. Background technique [0002] A reaction in which a substance decomposes when heated. Many inorganic and organic substances undergo decomposition reactions when heated to a certain extent. In the past, pyrolysis processes did not involve catalysts, as well as reactions induced by other energies such as ultraviolet radiation. At present, due to factors such as improving pyrolysis efficiency, increasing the yield of pyrolysis products, and preparing products that are not easy to prepare by conventional pyrolysis, more and more researches are carried out on catalytic pyrolysis by adding catalysts during the pyrolysis process. Some catalytic pyrolysis processes, such as adding catalysts such as CaO and MgO, have been used in industrial production. [0003] ...
