    • A cleaning-liquid circulation path (7) is formed so that cleaning liquid in a cleaning tank (1) is suctioned by a circulating pump (8) and circulated through a predetermined path and then, returned to the cleaning tank again. A deaeration device (9) for bubbling dissolved air in the cleaning liquid by cavitation is connected on the way of the cleaning-liquid circulation path so as to bubble the dissolved air in the cleaning liquid flowing through the cleaning-liquid circulation path by the deaeration device, and the bubbled dissolved air flows back to the cleaning tank together with the cleaning liquid so that the bubbled dissolved air is ejected from the liquid surface of the cleaning tank to the outside of the tank. Moreover, a propeller-type pump is used as the circulating pump, and the dissolved air concentration of the cleaning liquid is controlled within a range of 2.5 to 3.5 mg/l.
    • 清洗液循环通路(7)形成为使得清洗槽(1)中的清洗液体被循环泵(8)吸引并循环通过预定路径,然后再次返回清洗槽。 在清洗液循环路径上连接用于通过空化将溶解的空气吹入清洗液中的脱气装置(9),以使通过清洗液循环路径流动的清洗液中的溶解空气通过除气 装置,并且鼓泡的溶解空气与清洁液体一起流回到清洁槽,使得起泡的溶解空气从清洗槽的液体表面喷射到罐的外部。 此外,使用螺旋桨型泵作为循环泵,将清洗液的溶解空气浓度控制在2.5〜3.5mg / l的范围内。
