Efficient gas-liquid reactor

Abstract

The invention relates to an efficient gas-liquid reactor, which comprises a reactor body and a gas inlet pipe, wherein an agitation motor is arranged below the reactor body, a motor shaft of the agitation motor extends into the reactor body, a cover-shaped turntable which is positioned in the reactor body is installed at the upper end of the motor shaft, a group of air holes are produced in the cover body of the cover-shaped turntable, the gas inlet pipe is coaxially sleeved on the motor shaft, and the gas outlet of the gas inlet pipe is positioned in the cover-shaped turntable. The efficient gas-liquid reactor provided by the invention has a reasonable design and a simple structure, is easy to produce and has high practicability, the reactor is added with the cover-shaped turntable which has an agitation function, a plurality of air holes are arranged in the cover-shaped turntable and can produce a large quantity of small bubbles during the rotation process, so the gas-liquid contact surface area for unit gas quantity is greatly increased, the gas-liquid reaction speed is accelerated, and the reaction efficiency is improved.

Description

technical field [0001] The invention relates to the field of reactors, in particular to a high-efficiency gas-liquid reactor. Background technique [0002] Gas-liquid reaction is very common in chemical production. For example, the production method of benzoic acid is to pour the toluene solution into the reactor, then feed air into the reactor for oxidation and catalytic reaction, and finally generate benzoic acid. When air enters the solution, bubbles will be generated. The oxidation reaction is the reaction between the oxygen in the bubbles and the toluene in the liquid phase. The smaller and more the bubbles, the more surface area the gas-liquid contacts, and the better the reaction. Since the existing reactors are filled with air at the lower part, and because the gas distributor mainly relies on the injection of gas, the gas-liquid mixing effect is poor, and the bubbles formed are larger and less, resulting in incomplete reaction and ultimately affecting product qualit...

AI Technical Summary

Problems solved by technology

Since the existing reactors are filled with air at the lower part, and because the gas distributor mainly relies on the injection of gas, the gas-liquid mixing effect is poor, and the bubbles formed are larger and less, resulting in incomplete reaction and ultimately affecting product quality. and production speed

If the outlet aperture of the intake pipe is reduced and high-pressure air is injected, small air bubbles can be produced, but it is difficult to realize due to its large resistance and high energy consumption.
