Principles of Acoustic Scale Prevent Technology：　   

    The Acoustic Scale Preventer consists of a generator and a magnetostrictive energy transducer(referred to as the transducer). The pulse signal generated by the generator is transmitted via cable to the transducer, where it is converted into 10–25 kHz acoustic oscillations. These oscillations propagate along the metal components of the heat exchange equipment (e.g., tube sheets) to the heat transfer surfaces, achieving descaling and scaling preventing effects.
   Acoustic Scale Prevent Technology leverages the hard and brittle mechanical properties of scale deposits to function. When the acoustic oscillations generated by the transducer propagate along steel of heat exchanger to the heat transfer surfaces, attached scale deposits—including iron-containing compounds that are difficult to remove even with chemical treatments—continuously detach. Additionally, bending vibrations in the pipeline create tangential mechanical tension at residual scale locations, inducing cracks in the scale. Water then infiltrates these cracks. As the water in the cracks is heated by the hot pipe wall and expands, combined with the shear forces generated by pipeline vibrations, the scale breaks into chunks and is carried away by the fluid flow. In essence, Acoustic Scale Prevent Technology exploits the significant disparity in vibrational modes between scale deposits and metal heat transfer tubes. When forced vibrations are applied to the metal tubes, the scale—due to its poor elasticity—fails to synchronize with the tube's vibration mode. This mismatch generates tangential stresses that disrupt the scale’s adhesion, leading to its detachment.
   The acoustic oscillations also contribute to remove oxygen-containing bubbles trapped in micropores and cracks on the pipe wall surface, while reducing the supersaturation of dissolved oxygen in water. This mitigates oxidative corrosion on the pipe wall and delays under-deposit corrosion.
   In fact,all physical energy fields (including ultrasound), can’t prevent the chemical process of calcium/magnesium compounds deposition on heat exchange surface in aqueous media. Instead, Acoustic Scale Prevent Technology is the only physical method with the feature of online descaling. By continuously stripping away scale deposits in real time, the technology establishes a dynamic equilibrium between descaling and scaling. As long as the descaling rate exceeds the scaling rate, the heat exchange equipment remains scale-free during operation.
  The unique reliance on the mechanical properties of scale (rather than liquid-phase media or chemical composition) enables this technology to address globally challenging scaling issues in chemical production processes. This mechanical approach ensures broad applicability, regardless of the scale’s chemical makeup.
