Gas liquid reaction kettle adopting spherical crown-shaped micropore corundum gas supply apparatus

Abstract

The invention relates to a gas liquid reaction kettle adopting a spherical crown-shaped micropore corundum gas supply apparatus. The gas liquid reaction kettle comprises a reaction kettle body and a gas supply device, the reaction kettle body comprises a main kettle body, the gas supply device comprises the gas supply apparatus, the gas supply apparatus is arranged in the main kettle body, and thetop surface of the gas supply apparatus is a spherical surface; the gas supply apparatus is in a spherical crown shape and is of an integrated structure, and upper and lower surfaces of the gas supply apparatus release gas simultaneously; the gas liquid reaction kettle has the advantages of a large gas supply amount, high stirring intensity, low resistance, high efficiency, low consumption, reliable operation, no blockage, ageing resistance, corrosion resistance, long service life and the like; in addition, the superficial area of contact between gas and liquid is greatly increased through alarge number of fine bubbles, the reaction speed is increased, and the reaction efficiency is improved; in addition, during gas supply, a high self-stirring effect of a large number of small bubbles is achieved, a stirring device of a conventional gas liquid reaction kettle does not need to be arranged, the structure can be simplified, the cost is reduced, and if the stirring device is arranged, the speed and efficiency of a gas liquid reaction can be further improved.

Description

technical field [0001] The invention belongs to the technical field of gas-liquid reactors, and in particular relates to a gas-liquid reactor using a spherical crown-shaped microporous corundum gas supplier. Background technique [0002] The reactor is the most commonly used chemical reactor in the industrial production process. According to different process conditions, the structure design and parameter configuration of the container are carried out to realize the heating, evaporation, cooling and low-speed mixing reaction functions required by the process. The reaction kettle can carry out both homogeneous reaction and heterogeneous reaction. Generally, there is a stirring device inside it, which can make the concentration of the reaction material in the reaction zone of the reactor uniform. There are many types of reactors. According to the heating / cooling methods, they can be divided into electric heating, hot water heating, heat conduction oil circulation heating, far ...

AI Technical Summary

Problems solved by technology

However, limited by the processing and manufacturing of small air supply holes, the diameter is at least on the order of mm, so that the size of the bubbles is not small enough, the number is not enough, and the speed and efficiency of gas-liquid reaction cannot be fully utilized.

[0005] It can be seen that the above-mentioned various structures and methods for improving gas-liquid mixing in gas-liquid reactors are either complex in structure, high in cost, or have limited improvement effects, and have obvious deficiencies.
