Device for dissipation of mechanical energy from liquid e.g. petroleum, reservoir, has fan blades formed by dished or welded sheets, and obstacles arranged on walls of liquid reservoir, where each fan blade organizes vortices

摘要

The device has fan blades (1) formed by dished or welded sheets, where each fan blade organizes vortices. Obstacles are arranged on walls of a liquid reservoir for creating vortices in case of movement of liquid, where obstacles are arranged along directions. The blades are composed of two triangles located on both sides of plane of sheet. The vortices are turned in a same direction, thus increasing the dissipation of mechanical energy from liquid reservoir.
