[0002] In today's petrochemical industry field, the transportation link mainly relies on automobile and train tank car to realize the transfer of materials. However, after the loading operation on the top of the tank car is finished, the residual petrochemical products on the surface of the vertical pipe will drop by chance in the process of withdrawing the vertical pipe from the tank opening. This phenomenon not only destroys the overall neatness of the operation site, but also may derive many potential safety hazards and environmental problems. For example, the chemical products dropped on the ground may pollute the air due to volatilization, and under the action of high temperature or fire source, there is even a risk of fire or explosion; moreover, the long-term accumulation of chemical product residues will also pollute the soil and water, increasing the environmental governance cost of enterprises.
