  • Aeration efficiency is high due to functions of vacuum, cavitation, and air suction powered by kinetic energy of the flow. Saturation of air gases has been achieved within treatment of few seconds in brief tests. Energy consumption is little compared with typical prior art technologies. In flowing waters like rivers and water piping, the aeration can be executed without additional energy. Further, the air is sucked out of the water surface that ensures clear air dissolving and avoids dissolution of reaction and bio gases back into the water as many recent aerators do.
  • Dissolving is fast and efficiency high, and energy consumption low for soluble gases like oxygen, ozone, carbon oxide, nitrogen etc.
  • a mixing and dissolving tube comprising a multi-channel nozzle head of the kind describe above ensures even dissolving of the treated liquid. This is a very important feature in industrial water treatment and disinfection in general. Bacteria can be killed by the treatment, and energy and ozone can be saved.
  • Bacteria and viruses can be killed in water by ozone feed or suction due to even mixing feature of a mixing and dissolving tube of the kind described above.
  • a mixing and dissolving tube of the kind described above improves flotation processes due to its high performance and even gas suction, mixing, and dissolving.
  • the liquid to be treated by flotation can be led through the mixing and dissolving tube in total, pretreated with desirable chemicals and feed air in it to create bubbles for the flotation separation.
  • the mixing and dissolving tube ensures separation efficiency and low energy consumption by the continuous treatment and separation without stopping the flow.
  • a mixing and dissolving tube of the kind described above can be integrated in household water supply systems like taps and showers to enrich the water with clear air.
  • the specific examples provided in the description given above should not be construed as limiting. Therefore, the invention is not limited merely to the exemplifying and non-limiting embodiments described above.

Abstract

Un tube de mélange et de dissolution comprend une tête de buse (101) et un élément de tube (102) entourant la tête de buse. Une paroi de l'élément de tube comprend au moins une ouverture (103) pour faire passer un écoulement latéral soumis à une aspiration provoquée par un écoulement principal. L'élément de tube comprend une section d'étranglement (104) située après la tête de buse dans une direction d'écoulement. Le tube de mélange et de dissolution comprend en outre au moins un élément de guidage d'écoulement (105, 106) pour générer un écoulement à tourbillon à deux têtes après la section d'étranglement dans la direction d'écoulement. La tête de buse accélère l'écoulement principal et crée l'aspiration qui accélère l'écoulement latéral. La section d'étranglement mélange les écoulements principal et latéral pour produire un mélange uniforme et ralentit l'écoulement accéléré. L'élément de guidage d'écoulement améliore le mélange, et l'écoulement à tourbillon à deux têtes réduit les turbulences et les pertes dans une tuyauterie par rapport à un écoulement continu droit.
