FIELD: process engineering. ^ SUBSTANCE: invention relates to ultrasound cleaning of process and operating impurities. Proposed method consists in the following. Article placed in vessel with detergent is subjected to ultrasound oscillations generated by the main high-amplitude radiation source that provides 15 to 20 mcm amplitude of oscillatory displacements and 20 to 30 kHz frequency, and generates fluid flow with cavitation properties directed onto article. Note that additional power flux is directed to said article. Note also that low-amplitude ultrasound radiation power is used that creates, together with the main source radiation, a common zone distant from the latter which brings about a stable cavitation effect on the article due to interaction of two acoustic flows. Said common zone extends for L=(4-5) l, where l is the distance from the main source active acoustic effect length. ^ EFFECT: additional zone of erosion effects in detergent wherein no destruction of impurities occurs. ^ 1 dwg |
