AI Technical Summary
Expanding the existing accident oil pool requires demolition and reconstruction, which results in high costs and makes it impossible to collect the leaked oil during the demolition and reconstruction process, potentially polluting the ecological environment.
A series structure is adopted to connect the newly built emergency oil tank with the existing emergency oil tank. The volume is expanded by connecting pipes and diversion mechanism, the oil-water separation time is extended by using diversion wall, and the oil absorption layer is combined to prevent oil from flowing into the outside.
It enables capacity expansion without dismantling the original oil tank, reducing costs, preventing oil pollution of the ecological environment, and ensuring effective oil-water separation.
