The tank truck body 10 can be connected with the storage tank 200. Since the high-level water tank 100 is located above the tank truck body 10, the compressed carbon water in the high-level water tank 100 uses the height difference to increase the water pressure, and the compressed carbon water is transported to the tank truck body 10, so that the carbon disulfide in the tank truck body 10 is pressed out into the storage tank 200.
