The invention relates to the technical field of generation and transfer of
ultrasonic vibration and particularly relates to a near
sound field ultrasonic reactor which efficiently uses ultrasonic energies. The near
sound field ultrasonic reactor comprises an
ultrasonic vibration tube, an ultrasonic internal reflection tube, an ultrasonic external reflection tube, an ultrasonic amplitude
transformer, a
flange connected with the ultrasonic amplitude
transformer, an ultrasonic amplitude
transformer flange, a fixed amplitude transformer sleeve, a fixed internal reflection tube rib, an internal reflection tube dividing conehead, an external reflection tube
flange and the like. The ultrasonic reactor provided by the utility model is the near
sound field ultrasonic reactor which is simple in structure, free from maintenance in operation, high in utilization ratio of ultrasonic energy, large in ultrasonic radiating area, uniform in ultrasonic
sound intensity, low in
power consumption and energy-saving and
environmentally friendly and efficiently uses ultrasonic energies. The near sound field ultrasonic reactor provided by the utility model not only effectively utilizes radiating energies on the internal and external faces of the ultrasonic vibrating tube, but also effectively utilizes radiating energies reflected from inner and outer sides, so that the near sound field ultrasonic reactor is suitable for industrial flows in
continuous production. A common plate type ultrasonic reactor is not as good as the near sound field ultrasonic reactor.
