The invention discloses a jacket continuous parallel orthogonal multi-frequency chemical reactor. Wherein, the liquid distributing groove is connected to the cycle pump; the cycle pump, the first valve, the rotator flow gauge and the second valve are connected; the second valve is connected to the inlet of reaction room; the outlet of reaction room is connected to the liquid distributing groove and the discharge groove; the reaction room is rectangular while its two opposite walls are mounted with groups of ultrasonic energy exchanger which are formed by several paster-type ultrasonic energy exchangers; the top of reaction room is mounted with a detector-type ultrasonic energy exchanger. Said invention can be used in groups and control the power via external current; when parallel or orthogonal ultrasonic waves are used, the sonic field will be wider with more uniform distribution; the jacket structure will cool it to keep constant temperature. And ti can be used in sonic chemical reaction technique.
Description
technical field [0001] The invention belongs to the field of sonochemical reaction devices, in particular to a continuous parallel orthogonal multi-frequency sonochemical reaction device with a jacket structure. Background technique [0002] Ultrasound refers to elastic waves with a frequency range higher than that which can be heard by the human ear (ie > 16-20KHz). Sonochemistry refers to a new interdisciplinary subject that uses ultrasonic irradiation to accelerate chemical reactions and improve productivity. [0003] Sonochemical reactions do not result from the direct interaction of sound waves with molecules of matter, because the wavelengths of sound waves commonly used in liquids are much larger than the molecular scale. Sonochemical reactions originate primarily from acoustic cavitation—the formation, oscillation, growth, shrinkage, and collapse of cavities in liquids, and the resulting physical and chemical reactions. The process of liquid acoustic cavitation i...
