[0030] A production line for making biochar and extracting biomass vinegar of the present invention comprises the following steps:

[0031] Picking green tea: It starts from the Jingzhe Festival of the 24 solar terms. After the spring rain, the newly grown buds are picked manually to make spring tea. In this stage, the tea is picked manually to ensure the quality of the buds and reduce the subsequent screening process. After picking, the sieve is placed in a sink of spring water and the buds are placed in the sink for cleaning to remove the stains on the surface. After cleaning, the sieve is picked up and placed on a vibrating base with a vibration of 10mm / s and an indoor temperature of 15°-20°. It is placed for 4-5 hours and taken out. S1. Waste pretreatment and transportation: The green waste and wood waste are crushed, and the flake or block solids are stacked on the loading vehicle in the loading area.

[0032] S2, Processing 1: An electromagnetic heating pipeline is provided, and S1 is transported to the electromagnetic heating pipeline at a constant temperature of 360-400°C and a pressure of +10kp.

[0033] S3, Processing 2: A first cooling pipeline is provided at the rear end of S2, and S1 is further transported to the cooling pipeline, in which plasma water mist cooling is provided at a pressure of +15 to +20 kp.

[0034] S4, processing three: a second cooling pipeline is set at the rear end of S3, and S1 is further transported to the cooling pipeline. The cooling pipeline has the same structure as the cooling pipeline in S3, and is also equipped with plasma water mist cooling. Here the pipeline is under a pressure state of +4 to +8kp.

[0035] S5, recovery: S1 automatically drives out from S4, continues to move forward, reaches the unloading area, unloads by turning over, and after unloading, the empty loading crane is used to return to the loading area through a crane.

[0036] S6. Biomass vinegar extraction: Pressure relief pipes are set every two meters on the inner walls of S2, S3 and S4. The pressure relief pipes are used to relieve pressure and condense and collect liquid organic acids. The end point of the pressure relief pipe is set at the bottom of S2, where a biomass vinegar recovery device is installed.

[0037] S7, smoke recovery, environmental protection and sealing, high temperature resistant automatic valves are set at both ends of S2, S3 and S4, and smoke recovery pipes are set on S2, S3 and S4.

[0038] During processing, firstly, green waste and wood waste are pre-processed in S1, such as crushing, and the flake or block solids are stacked on the loading vehicle in the loading area. At this time, the first high-temperature resistant automatic valve in the electromagnetic heating pipeline in S2 is opened, and the loading vehicle is driven into the electromagnetic heating pipeline to close the high-temperature resistant automatic valve. At this time, the electromagnetic heating pipeline is in a sealed state, and the internal environment of the electromagnetic heating pipeline is set to a constant temperature of 360-400°C and a pressure of +10kp through the set program. The processing is 1-1.5 hours. In this process, the waste is processed into biochar blocks through high temperature. At the same time, during the heating process, the waste is heated to undergo a pyrolysis reaction at high temperature. During the pyrolysis process, the organic components in the biomass raw materials will decompose into gas, liquid and solid products, among which the liquid product contains the main components of biomass vinegar, which flows into the recovery device through the set pressure relief pipeline to collect and recover the biomass vinegar.

At this time, the loading carriage will automatically drive into S3. Several nozzles are installed in S3 to spray plasma water mist to cool the carbon blocks in the loading carriage in S1 to 100°C. After the temperature sensor detects that the internal temperature reaches the standard, the subsequent high temperature resistant automatic valve is controlled to open, so that the loading carriage enters S4 for the second cooling. After the temperature is controlled to 50-60°C, the last high temperature resistant automatic valve is opened after monitoring by the temperature sensor to drive the loading carriage out to the unloading area. The mist generated during the entire production process will be recovered and processed through the set smoke recovery pipeline.

[0040] After arriving at the unloading area, a crane is installed in the unloading area to assist the loading crane to flip the carbon blocks and pour them into the unloading pool. After the carbon blocks are cleaned, they are transported to the loading area of ​​S1 for circulation by the crane, and a screw conveyor is installed in the unloading pool to transport the carbon blocks to the packaging area for packaging.
