Abstract (en)
[origin: WO2010076446A1] The invention relates to a device for reducing fouling inside a tube (1) through which a fluid (F) flows, comprising at least one turbulence generation device, said device comprising a mobile rotary element (2) connected to a stationary bearing element (3) rigidly connectable to the upstream end of the tube (1), said mobile rotary element (2) including an upstream portion (4) defining a journal and including a mechanical link (5) with the stationary bearing element (3) and enabling the free rotation of the mobile element (2) on itself about the axis of the tube (1), a helix-shaped downstream portion (6) including a plurality of turns and shaped so as to be rotated by the flow of fluid (F) in the tube (1), wherein the upstream (4) and downstream (6) portions of the mobile rotary element (2) are connected to each other by an elongate flexible connection capable of deformation along the entire length thereof (7), and the downstream portion (6) comprises at least one turn potion having a pitch (8) that is reversed relative to the pitch of the other turns. The invention also relates to a heat exchanger including a plurality of tubes through which a fluid flows and including at least one fouling-reducing device.
