Ultrasonic debubbling method and apparatus

摘要

A method for debubbling a liquid includes flowing the liquid into an inlet, applying high energy ultrasonic waves to the liquid inside the inlet, introducing the liquid into a debubbling chamber through the inlet and applying low-energy ultrasonic waves to the liquid in the debubbling chamber to obtain a debubbled liquid. An ultrasonic debubbling apparatus comprises a medium chamber containing a heat and ultrasonic wave transmitting medium, a debubbling chamber inside the medium chamber, an introducing pipe arranged to extend a predetermined length into the medium chamber so as to introduce the liquid to be debubbled into the debubbling chamber, a primary ultrasonic transducer for applying high energy ultransonic waves to the liquid in the introducing pipe and a secondary ultrasonic transducer for applying low energy ultrasonic waves to the liquid in the debubbling chamber.
