The pyrolysis heating device 10 includes a feed end (the right end shown in the figure) and a discharge end (the left end shown in the figure). As a method for treating organic solid waste, pyrolysis technology has the advantages of high treatment efficiency, low pollution, and high resource recovery rate, and can convert organic solid waste into high value-added carbon powder. As an important industrial raw material, carbon powder has a wide range of applications in metallurgy, chemical industry, environmental protection and other fields. Therefore, pyrolysis technology has great potential in the utilization of organic solid waste. Optionally, the pyrolysis heating device 10 can use a heating furnace, and the heating furnace can use an alumina fiber lining to ensure rapid heating and low heat storage in the furnace. A heating element and a temperature measuring element are provided in the heating furnace.

[0039] For a long time, laboratory research on organic matter pyrolysis has been mainly based on sequencing batch experiments. Although this method provides a basic platform for research, it cannot achieve continuous material input and output, resulting in significant deviations between experimental results and actual industrial production. Sequencing batch experimental equipment has limitations in material supply, heat transfer, and stability of the experimental process, making it difficult to accurately simulate the continuous pyrolysis process in actual production.

[0040] Therefore, the resource recovery equipment for organic matter in solid waste provided by the present application is adopted, and the organic material is subjected to pyrolysis reaction through the pyrolysis heating device 10 to generate solid-phase carbon powder and gas-phase pyrolysis oil and gas.

[0045] Furthermore, the pushing mechanism 24 penetrates one end of the pyrolysis heating device 10, and further penetrates the separator 30 after passing through the pyrolysis heating device 10 from the discharge end, so that the organic material after the pyrolysis heating reaction can be sent to the separator 30 for separation.
