Title: DEVICE FOR FLUID RECIRCULATION AND TANK CLEANING, AND STORAGE TANK
Abstract:
The present invention relates to a device (1 ), able to allow for the supply of a pressurized fluid to inner portions of tanks (2) for fluid storage (e.g. petroleum), so as to enable its cleaning or the recirculation of the stored fluids. Such device (1 ) comprises at least a means for fluid conduction (3) able to allow for the flow of pressurized fluids inside the tank (2). Besides, the device (1 ) also comprises at least a revolving element (4), able to allow the flow of pressurized fluids to change its direction inside the tank (2), associated to the means for fluid conduction (3). Additionally, the device (1 ) comprises a main basis (5) fixed at the tank and having a central orifice which houses the revolving element (4). Said revolving element (4) is arranged to move rotationally around a first geometrical central axis x and around a second geometrical central axis ӯ, wherein the first geometrical central axis x and the second geometrical central axis ӯ form together an angle different from zero. The present invention also relates to a tank for fluid storage (2) which comprises a device (1 ) for fluid recirculation and tank (2) cleaning, as previously mentioned.
