The uppermost charcoal-making channel 2 is a drying channel 10 for drying the material on the material cart 3. The temperature in the drying channel 10 is 100-200 degrees Celsius. The charcoal-making channel 2 on the second layer is a pyrolysis channel 14 for low-temperature pyrolysis of the material on the material cart 3. The temperature in the pyrolysis channel is 200-500 degrees Celsius. The charcoal-making channel 2 on the third layer is a calcination channel 36 for high-temperature calcination of the material on the material cart 3. The temperature in the calcination channel 36 is 500-800 degrees Celsius. The charcoal-making channel 2 on the bottom layer is a cooling channel 37 for cooling the material on the material cart 3. The heat in the calcination channel 36 can be used to supplement the heat of the drying channel 10 and the pyrolysis channel 14 on the upper side. An oxygen supply pipe is provided at the bottom of the calcination channel 36, through which the temperature of the material in the calcination channel is controlled, and the material in the calcination channel is in an oxygen-deficient / low-oxygen combustion state to prevent the material from burning too violently and causing a reduction in products, and to avoid oxygen in the tail gas, which affects hydrogen production.

When the material cart 3 moves into the high temperature rotary furnace 7, the push rod 23 pushes the docking plate 24 to move toward the high temperature rotary furnace, the positioning pin 16 will pass through the first card slot 15 and the second card slot 19, and the material cart 3 will be locked in the high temperature rotary furnace 7, and the docking shaft 17 will be engaged with the docking slot 25, so that the high temperature rotary furnace 7 can be driven to rotate during the rotation of the rotating shaft 22, and the rotating shaft 22 is driven by an external motor. The material in the material cart 3 is a bundle of materials, and the material is turned over and high temperature calcined during the rotation of the high temperature rotary furnace 7 to prevent the material in the middle of the material cart from being carbonized incompletely.

[0035] When the present application is in use, when the present application is assembled, the container body 1 can be assembled by a crane, or the container body 1 can be transported by a trailer. After being transported to the designated position, the container body 1 is lifted by a supporting mechanism, so that the trailer can be separated from the container body 1, and the trailer can continue to transport the container body 1. A new container body 1 is set on the lower side of the original container body 1. After the construction is completed, a transfer lifting platform is installed, the container body 1 is in an elevated state, and the transfer lifting platform 5 can be moved to the ground. A guide slope corresponding to the transfer lifting platform 5 can be laid on the ground, so that the material car can move onto the transfer lifting platform 5. First, the rotating layer lifting platform can drive the material cart to move to one side of the drying channel 10. At this time, the hydraulic cylinder sealing door 32 will push the material cart into the drying channel 10. After the material cart 3 is completely pushed into the drying channel 10, the sealing door 34 will combine with the drying channel 10 to form a seal. In the process of the hydraulic cylinder sealing door 32 pushing the material cart to move, the material cart will push the material cart originally in the drying channel 10 to move out of the drying channel, and enter the pyrolysis channel 14 for pyrolysis under the action of the rotating layer lifting platform, and then it will be sent to the calcination channel 36 for high-temperature calcination. In order to prevent the material in the middle of the material cart from being incompletely calcined, A converter high temperature chamber 20 and a high temperature rotary kiln 7 are arranged at the discharge end of the calcining channel 36, and the material cart will enter the installation cavity 18 of the high temperature rotary kiln, and then under the action of the push rod 23, the positioning pin 16 on the docking plate 24 will pass through the first card slot 15 and the second card slot 19 to lock the material cart 3, so as to prevent the material cart 3 from being separated from the high temperature rotary kiln 7 during the rotation of the high temperature rotary kiln 7, and the docking shaft 17 will cooperate with the docking groove 25 to drive the high temperature rotary kiln 7 to rotate, and the rotating shaft 22 is driven by an external motor, and the support roller 21 can support the high temperature rotary kiln 7 to reduce the burden of the rotating shaft 22. The materials on the material cart 3 are arranged in bundles, and during the rotation of the high temperature rotary kiln 7, the materials can be turned over and calcined at high temperature to fully carbonize the materials. After calcination is completed in the high-temperature rotary furnace 7, the push rod 23 will move away from the high-temperature rotary furnace 7 to release the lock on the material cart 3. Under the action of the hydraulic cylinder sealing door, the new material cart will move into the installation cavity of the high-temperature rotary furnace 7, and the raw material cart will be lifted onto the rotary lifting platform 5. It will be transported to the cooling channel 45 of the cooling cabin through the rotary lifting platform 5, and enter the cooling channel under the action of the hydraulic cylinder sealing door 32 for cooling. After cooling, it will be sent out through the inlet and outlet 9.

[0036] During the carbonization process, a large amount of pyrolysis gas and tail gas will be generated, which will be collected through the tail gas collection pipe 57 and transported to the tail gas treatment device for treatment, which can remove harmful gases in the tail gas and collect and utilize components such as methane in the pyrolysis gas. If hydrogen production is to be carried out, a catalyst is added to the tail gas box 39 and pressure swing adsorption is performed to produce hydrogen. The harmful components in the tail gas will be absorbed by the agent spray in the spray tower 41 to obtain hydrogen.

[0037] Embodiment 2. On the basis of embodiment 1, the container body 1 is divided into three groups, and the six carbon-making channels 2 are, from top to bottom, a drying channel 10, three groups of pyrolysis channels 14, a group of calcination channels 36, and a group of cooling channels 37. The purpose of setting up three groups of container bodies 1 is that during the carbonization of biomass materials, the time required for the pyrolysis process is longer than the time required for high-temperature calcination. In this way, two groups of pyrolysis channels 14 for material pyrolysis are added, so that the three groups of pyrolysis channels can be operated simultaneously, matching the processing efficiency of the calcination channels used for high-temperature calcination of materials, thereby improving the carbon-making efficiency.
