| 摘要 |
The invention relates to a device (10) for an operation of skimming petrochemical or chemical fluid process or storage tanks operating by gravitation comprising buoyancy means (20), collection means (30) for collecting the surface fluid to be skimmed off, comprising an opening (31) opening above the interface between the fluid of density d1 and the fluid of density d2 and connection means (32), and discharge means (40) of removing the surface fluid collected. The discharge means (40) comprise at least two flexible pipes (41, 42) connected symmetrically to the connection means (32) and extending vertically into the fluid of density d2 toward the bottom of the tank. |
