Ultrasonic cleaning method and device therefor

Ultrasonic cleaning device for cleaning an inside portion of a polygonal tube having an axis, the device comprising:

• a plurality of ultrasonic transducers irradiating ultrasonic waves towards the tube from an exterior portion of the tube and from at least two directions;
• a support member supporting the tube;
• an ultrasonic transducer transferring mechanism moving said ultrasonic transducers along the axis of the tube;
• a cleaning liquid supply mechanism arranged outside the tube, said supply mechanism supplying cleaning fluid into the tube;
• a cleaning liquid discharge mechanism discharging the cleaning liquid from the tube;
• and
• an ultrasonic wave leakage prevention structure preventing leakage of ultrasonic waves from the ultrasonic transducers to areas external of the device wherein said ultrasonic wave leakage prevention structure comprises a stainless steel wire mesh enclosure.
