Research on Descaling Characteristics and Simulation Calculation of a Coaxial High-Frequency Electronic Descaling Device

High-frequency electronic descaling devices are physical water treatment methods that use a high-frequency electromagnetic field to prevent and remove scale. The effectiveness of the method is verified by monitoring growth scale on surface heat exchange tubes. microstructure obtained from experiments analyzed scanning electron microscope (SEM), action characteristics fields explored observing change solution contact angle at different times. experimental results show can slow down scaling tubes changing morphology substances physicochemical properties water. cavity instrument modeled simulated ANSYS Maxwell, three operating parameters, waveform, voltage frequency, changed respectively. performance parameters cavity, such as magnetic energy, electric energy flux, calculated compared, then more suitable selected improve instrument. simulation generated anode rod in axial position be overlooked compared with energy. Square wave excitation produces greater than using sine excitation, increases, peak value continues rise increases faster. With an increase flux will maintain slight decrease over certain frequency range. After this range, rapidly. This due relaxation caused waveform direction. influence time significantly time.
