Ultrasonic wave Main Function principle of antiscaling, descaling in condenser of power plant is:
1, cavitation effect
The radiate ultrasound energy of ultrasonic transducer 2 is in cooling circulating water, make in water, to produce a large amount of holes and bubble, when these holes and bubbles burst or when mutually extruding, powerful pressure spike can be produced, make into dirty material comminuted suspension in water, and make the dirty layer fragmentation generated cause it to be easy to come off.
2, activating effect
Ultrasonic wave passes through cavitation effect in cooling circulating water, hydrone is cracked into H free radical and HO free radical, even H+ and OH-etc., and OH and the complex becoming dirt substance ion can form such as Ca (OH) 2, Mg (OH) 2 etc., thus increase the solvability of water, its solubility for scale is improved relatively, there is activating effect.That is, ultrasonic wave can improve working fluid and the activity becoming dirty material, the release of the one-tenth dirt material microcrystals that increase is wrapped in by hydrone, destroy the existence of dirty class and the condition in tube wall attachment, make into dirty material in water, form dispersed deposition body and on tube wall, do not form hard scale, thus play anti-scaling action.
3, shearing effect
The ultrasonic wave vibration acting on metal surface creates mechanical energy, metal, incrustation scale, water are shaken thereupon, because the frequency response between three is different, produce non synchronous vibration, because the condition of dirty matter is different with metal with elastic impedance, therefore relative motion is at a high speed produced, form the relative shear on dirty layer and tube wall interface, namely shearing effect is formed, destroy the combination between incrustation scale and metal, cause dirty layer to produce fatigue, crackle, loose, fragmentation and coming off, thus play scale removal effect.
4, depression effect
By hyperacoustic effect, change the physicochemical properties of main body of liquid, shorten into the nucleation induction period of dirty material, have stimulated the generation of small nucleus.These newly-generated small nucleus, because volume is little, quality is light, specific area is large, be suspended in liquid, generate the interface more much bigger than wall, there is the ability of very strong contention water intermediate ion, ion can be suppressed at the nucleation and growth at wall place, allow the grain growth of given structure, because this reducing the quantity adhering to incrustation ion on heat-transfer surface, thus it also reduce the sedimentation rate of incrustation.
5, high speed microvovtex effect
When ultrasonic wave is propagated at metal tube, wooden partition, produce high acceleration Sasser, make to produce high speed microvovtex with the liquid of this interracial contact, hinder the attachment of the materials such as fouling, crystallization, incrustation, metal interface is cleared up simultaneously, serve the double action of antiscale and scale removal.
