A near sound field ultrasonic reactor

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of generation and transmission of ultrasonic vibrations, in particular to a near-sound-field ultrasonic reactor that utilizes ultrasonic energy efficiently. Background technique [0002] With the development of ultrasonic technology, sonochemistry began to form as a new branch of chemistry. The emergence of sonochemistry has attracted the attention of many advanced countries and invested manpower and material resources in research. Due to the vibration of medium particles caused by ultrasonic waves, it can generate great speed and acceleration, and can transmit a large amount of energy to medium particles. When propagating in liquid, it can produce cavitation effect, activation effect, polymerization effect, shear effect, mechanical thermal effect, etc. A series of physical effects, so that the ultrasonic has the functions of dispersing, pulverizing, activating, etc., which can make the reaction process onl...

AI Technical Summary

Problems solved by technology

However, this kind of reactor is not very compatible with other equipment in the field application, and it occupies a large area, and uses more transducers, which increases the failure points. In addition, the service life of the parallel plate is limited

The ultrasonic field of the reactor is not uniform due to the structure of the rectangular channel of the reactor. There are many weak and dead corners of cavitation in the reaction field, and there is the problem of uneven ultrasonic cavitation. In the large-scale continuous production process, it may There will be unstable product quality

In addition, in terms of effective utilization of ultrasonic energy, there are also cases where only the energy on one side of the ultrasonic radiation surface is used, while the energy on the other side is not utilized.
