Double-system temperature controlled acoustochemical reactor

Abstract

A double-system temp-controlling acoustochemical reactor is composed of a dual-wall reaction liquid tank, an ultrasonic generator, a temp controller, an ultrasonic transducer, a cavity between both walls with cooling medium inlet and outlet, a flow controller at cooling medium inlet, and cooling medium in said cavity between both walls. Its advantages are high reaction speed, autocontrol of reaction liquid temp and less consumption of catalyst.

Description

Technical field [0001] The invention belongs to the technical field of methods or equipment for the generation or transmission of sub-sonic, sonic or ultrasonic mechanical vibrations for general mechanical operations, and specifically relates to the use of electric energy to generate sub-sound, acoustic, or electric energy using piezoelectric effect or electrostrictive work. A method or device for mechanical vibration at audio or ultrasonic frequencies. Background technique [0002] In order to speed up the chemical reaction and reduce the amount of catalyst used, ultrasonic waves are usually applied to the chemical reaction liquid, and the cavitation effect generated by the ultrasonic wave in the chemical reaction liquid, that is, the local high temperature and high pressure effect generated when the cavitation bubble is closed, is realized. Chemical reactions that cannot be achieved by conventional means. [0003] In the existing sonochemical reactor, an ultrasonic transducer i...

AI Technical Summary

Problems solved by technology

The sonochemical reactor is not equipped with a cooling system on the reaction liquid tank, so that during the sonochemical reaction, part of the sound energy is converted into heat energy, resulting in an increase in the temperature of the reaction liquid, and for a long period of time, the reaction liquid The temperature changes with ti
