Intermittent ultrasonic reaction device

Abstract

The invention discloses an intermittent ultrasonic reaction device. The intermittent ultrasonic reaction device comprises a protective cover, ultrasonic acoustical systems, a screw, a first throttle valve, an ultrasonic transmitting groove, first bolts, a four-way flow dividing pipe, pressure nozzles, first clamp nuts, a gas-liquid exchange reaction chamber, gas guide holes, second bolts, lead screws, third bolts, a cover, second clamp nuts, a supporting ring, double nuts, a second throttle valve, a third throttle valve, a fourth throttle valve, a fifth throttle valve, a booster pump, stirring paddles and a circulation liquid storage groove. According to the intermittent ultrasonic reaction device, under the action of ultrasonic cavatition, reaction liquid is refined more evenly and finely; in the crystallization process, crystal grains can be effectively refined, and the crystal grains can be prevented from growing up; the catalyst surface can be updated in time, and the catalyst activity can be kept; the device can be widely used in the large-scale process such as sewage treatment and chemical industry production.

Description

technical field [0001] The invention relates to a novel intermittent ultrasonic reaction device, in particular to an intermittent ultrasonic reaction device. Background technique [0002] Nowadays, in the process of industrial production, with the continuous improvement of the requirements for safety, efficiency, and cleanliness, some process strengthening technologies and equipment have attracted more and more attention. The three-phase system of gas, liquid and solid is the most common system in chemical industry. Effectively improving the efficiency of mass transfer and heat transfer is always a problem that needs to be solved in this system. Although devices such as fixed beds, fluidized beds, and high-gravity equipment have been widely used, especially high-gravity equipment creates a stable and adjustable centrifugal force field by rotating the liquid. It is stretched into a thin film and fine silk under the impact, resulting in a larger contact area between phases, w...

AI Technical Summary

Problems solved by technology

Although devices such as fixed beds, fluidized beds, and high-gravity equipment have been widely used, especially high-gravity equipment creates a stable and adjustable centrifugal force field by rotating the liquid. It is stretched into a thin film and fine silk under the impact, resulting in a larger contact area between phases, which improves the transmission speed, and makes the relative speed of the gas-liquid two-phase in the chemical unit operation of the equipment such as rectification, absorption and complex reaction Greatly improved, but the device still has complex structure, high energy consumption, reliability is not as good as the general tower equipment, especially the insufficient droplet refinement and unstable refinement, which affect the three-phase reaction and mass transfer efficiency and other problems
