Description

According to the prior art, such as the Chinese patent document CN201621489343.X, a rotary arch-breaking, high-material layer up-suction biomass pyrolysis and gasification charcoal gas cogeneration device, the disclosed technical solution overcomes the defect of easy bridging of biomass raw materials by combining the rotation of the middle section of the furnace body with the layered rotating grate, greatly improves the efficiency of pyrolysis and gasification and the product quality, and increases the scale of cogeneration of charcoal gas.

[0003] According to the technical solution disclosed by the invention, the biomass pyrolysis and gasification carbon gas cogeneration device in the prior art performs drying and collection and discharge of pyrolysis gas at the top, but the dry airflow generated during the drying process will dilute the pyrolysis gas product, resulting in a decrease in the concentration of the pyrolysis gas product. On the other hand, since the pyrolysis tank as a whole is a continuous feeding and discharging process, the bottom discharge easily leads to a difference in the descending speed of the material at the inner edge and the material at the center, which ultimately makes the pyrolysis processing time of the inner and outer layers of the material inconsistent, resulting in some materials being unable to be completely carbonized or being over-carbonized.
