Multi-frequency ultrasonic parallel radiation gas-liquid mass-transfer reaction device

Abstract

The invention discloses a multi-frequency ultrasonic parallel radiation gas-liquid mass-transfer reaction device, which comprises a compressor, a gas buffer tank, a gas flowmeter, a distributing plate, an ultrasonic bubbling reaction tower, a double-conductivity probe, a liquid-phase inlet, a liquid flowmeter, an air inlet, a thermometer, a drain outlet, a discharge hole, a liquid seal, a bubble characteristic parameter measuring instrument, an ultrasonic transducer and connecting pipes. When the device disclosed by the invention is used, a liquid phase enters the ultrasonic bubbling reactiontower through a liquid-phase inlet at the upper end of the ultrasonic bubbling reaction tower prior to the beginning of a reaction and is discharged from the discharge hole at the lower end of the ultrasonic bubbling reaction tower so as to form a continuous flow; and a gas phase enters the ultrasonic bubbling reaction tower from the bottom of the ultrasonic bubbling reaction tower through the distributing plate to form an overall counterflow with the liquid phase and react the mass-transfer reaction. The device disclosed by the invention has the characteristics of large and adjustable ultrasonic power range, large and evenly-distributed acoustic intensity density, high and visualized energy utilization ratio, capability of being in butted joint with other measuring instruments so as to carry out data real-time acquisition and monitoring treatment and the like.

Description

technical field [0001] The invention belongs to the field of sonochemistry, and relates to an ultrasonic mass transfer reaction device, in particular to a multi-frequency ultrasonic parallel radiation gas-liquid mass transfer reaction device. Background technique [0002] Interphase mass transfer reactions play an extremely important role in the fields of chemistry, energy, and environmental protection. The reaction rate of the interphase mass transfer reaction is mainly related to the mass transfer effect. [0003] Ultrasonic refers to the frequency of 2 × 10 4 ~2×10 9 Hz sound waves. Ultrasound, as a special form of energy, has the advantages of high frequency and orientation, and its operation is simple, low in equipment requirements, green and environmentally friendly, and it is widely used in the field of chemical mass transfer. Ultrasound can produce a series of physical effects, such as cavitation effect, turbulence effect, perturbation effect, interface effect a...

AI Technical Summary

Problems solved by technology

[0005] Most of the existing ultrasonic mass transfer reaction devices work intermittently, which mainly have the following defects: no gas-liquid two-phase flow, single ultrasonic frequency, and poor uniformity of ultrasonic field sound intensity

It is difficult to meet the needs of industrial applications due to low energy utilization efficiency, low degree of equipment visualization, and inability to effectively interface with other measuring instruments.
