  • Bubble elimination tube with acutely angled transducer horn assembly
    Patent number: 6620226
    Abstract: A debubbling apparatus for removing gaseous bubbles entrained in a liquid is taught which has improved dearation capacity. The debubbling apparatus includes a vessel including a liquid inlet, at least one well extending from the vessel, the at least one well having a liquid outlet, and an ultrasonic transducer horn residing in the at least one well, the at least one well and the ultrasonic transducer horn residing therein being positioned at an angle in the range of from about 20° to about 45° with respect to vertical. With the ultrasonic horn and well so angled, bubbles in the liquid in the at least one well are subjected to a buoyancy force, a drag force, and an acoustic wave force which yields a resultant force that drives the bubbles toward an upper wall section of the at least one well.
