Zusammenfassung: | Introduction. The creation of modern ultrasonic cavitation equipment for filtering working fluids in various technological processes is associated with the study of the interaction of a liquid load with ultrasonic emitters, taking into account the influence of the geometric shape of the cavitation chamber. The efficiency of the operation of ultrasonic cavitation devices for filtration is a rather urgent issue today and directly depends on the quality of this agreement. Problem statement. To build an ultrasonic filter with a regeneration effect and to increase its efficiency, it is necessary to create a calculation method that will take into account both the impedance of electro-acoustic emitters and the complexity of the geometric shape of the cavitation chamber. Development of calculation methods. The proposed method for calculating the geometric dimensions of the acoustic resonance system of the modular section of the tubular ultrasonic cavitator, which is excited by folded piezoelectric drive-emitters, which carry out longitudinal vibrations and are installed on the outer surface of the tubular vibrator. Simulation results. The results of modeling in the Abaqus Student Edition 2018 software environment are presented, confirming the possibility of creating ultrasonic flow cavitators, the vibrator, which are excited in a radial-flexion mode of vibration, for the technological process of ultrasonic cavitation filtration with the regeneration effect. Conclusions. The proposed calculation technique allows designing cylindrical ultrasonic cavitation filter chambers with a regeneration effect. Repeated practical verification of the presented method for calculating resonant acoustic systems has confirmed its sufficient accuracy under the applied assumptions. |
