FIELD: biology and medicine, petrochemical and chemical industry, gas and liquids purification, separation of suspended particles, cells in particular. SUBSTANCE: material in the form of particles dispersed in liquid is separated by ultrasonic resonance field, that in general is generated in multilayer combined resonator, that has dispersion in vessel, transducer and mirror. All layers ar in parallel to each other. Amplitude resonance growth of acoustic squeezing out in dispersion is provided due to presence of much more expressed growth of amplitude acoustic squeezing out in other layers, as compared to resonance one. The effect is achieved due to matching of multilayer resonator resonance frequency component and electrical frequency of excitation under simultaneous dismatching of own frequencies of transducer and electrical part of excitation. Due to that level of electrical power required for provision of separation process is significantly decreased. In general apparatus is used with all type of dispersions (solid, liquid and gas-shaped phases) and is especially useful in case of particles in water and also for separation of biological particles (cells). EFFECT: significant decrease of electrical power consumption required to provide process of separation. 2 cl |
