DEVICE FOR FLUID RECIRCULATION AND TANK CLEANING, AND STORAGE TANK

摘要

A device able to allow for the supply of a pressurized fluid to inner portions of tanks for fluid storage (e.g. petroleum), so as to enable its cleaning or the recirculation of the stored fluids is disclosed. The device includes a revolving element able to allow the flow of pressurized fluids to change its direction inside the tank. Additionally, the device includes a main basis fixed at the tank and having a central orifice which houses the revolving element. The revolving element is arranged to move rotationally around a first geometrical central axis x and around a second geometrical central axis y, wherein the first geometrical central axis x and the second geometrical central axis y form together an angle different from zero. A tank for fluid storage which includes a device for fluid recirculation and tank cleaning, is also disclosed.
