    • PURPOSE:To perform defoaming with high defoaming efficiency, by arranging a pipe for introducing solution to be defoamed comprising a spiral round pipe having a flat cross-sectional area and an ultrasonic wave generator in a heat insulating tank. CONSTITUTION:An ultrasonic wave is allowed to irradiate a solution to be defoamed when said solution flows through an introducing pipe 7 toward a defoaming tank 5 and air bubbles generated by cavitation crowd together. Because the introducing pipe 7 has an upwardly directed spiral form constituted of a flat round pipe, centrifugal force acts on the solution and air bubbles are gathered to the inner wall surface of the pipe 7 and rising. This solution to be defoamed is flowed into the defoaming tank 5 and large air bubbles are floated and separated while air bubbles flocculated by the irradiation from a second ultrasonic wave generator 9 are also floated and separated.
    • 目的:为了进行消泡效率高的消泡,通过在绝热箱中配置导入具有平坦的截面面积的螺旋形圆管和消声器的管, 构成:当所述溶液通过导入管7朝向消泡槽5流通时,允许超声波照射要消泡的溶液,并将气泡产生的气泡聚集在一起。 由于导管7具有由扁平圆管构成的向上方向的螺旋形状,所以离心力作用在溶液上,气泡聚集在管7的内壁表面并升高。 待脱泡的这种溶液流入消泡罐5中,并且由第二超声波发生器9的照射而絮凝的气泡也浮起并分离,浮选和分离大的气泡。
