The paper presents the activity developed developed in the field of polluted air purification from industrial shop (paint shops, foundries, welding constructions, forging, etc.).The advantages of using ultrasounds in the pollutant air filtration and purification process and an ultrasonic filter designed are presented considering the ultrasonic cavitation phenomenon.The main computational and construction elements of the ultra-acoustic system used in the design of the air filter are presented in the galaxy harmony nc paper.
The work focuses in the design of the main part of the ultrasonic system represented by ultrasonic transducer.In this case, the transducer network that is used in ultrasonic cavitation method consists of ten ultrasonic transducers.Each one of them consists of asymmetrical passive elements (reflector and radiant element).The design steps and the use of FEM as working method ucsb gaucho blue will provide the theoretical basis of the operation of the ultrasonic system so that it allows air filtration based on the ultrasonic acoustic cavitation phenomenon.
