Reaction kettle and three-phase flow catalytic reaction method applying same

Abstract

The invention relates to a reaction kettle and a three-phase flow catalytic reaction method applying the same. The invention aims to provide the reaction kettle high in production efficiency and meanwhile provide the three-phase flow catalytic reaction method applying the reaction kettle. The invention relates to the field of chemical industrial reaction equipment. In order to achieve the purpose, the reaction kettle comprises a kettle body, wherein a reaction chamber is formed in the kettle body; a flow guiding structure is arranged in the reaction chamber and comprises a permeating part; a feeding hole and a discharging hole are communicated with the flow guiding structure or the flow guiding structure comprises a first flow guiding structure and a second flow guiding structure; the feeding hole is communicated with the first flow guiding structure; the discharging hole is communicated with the second flow guiding structure; reactants are introduced through the feeding hole and then react after entering into the reaction chamber through the permeating part; acquired products are discharged from the discharging hole communicated with the flow guiding structure through the permeating part. Meanwhile, the invention also provides the three-phase flow catalytic reaction method applying the reaction kettle.

Description

technical field [0001] The field that the present invention relates to is a kind of field of chemical reaction equipment, especially relates to the field of three-phase flow reaction. Background technique [0002] In the prior art, in the field of chemical industry, two methods are commonly used for the reaction of liquid-phase and gas-phase substances in the dispersion system, and the production reaction catalyzed by solid-phase catalysts: [0003] The first is to use a fixed bed as a catalyst carrier to fix the catalyst in the reactor, and use the liquid phase and the gas phase in the dispersion system to mix and then contact the catalytic bed to realize the catalytic reaction. [0004] In this kind of reactor, the position of the catalyst in the reactor is relatively fixed, and the position of the catalyst in the reactor generally does not disperse and move, so there is no need to consider filtering and separating the catalyst and the product after the reaction is complet...

AI Technical Summary

Problems solved by technology

Such production equipment has a complex structure, which also increases the process steps in production, and also increases the loss probability of products and catalysts

The reason why such problems exist in the prior art is that those skilled in the art have not designed a suitable filter structure that can be installed in the reactor and will not cause damage to the original equipment in the reactor. Secondly, the working environment in the reaction kettle is generally corrosive and harsh in chemical reactions. It is difficult to find a filter material that can perform filtering, back blowing and mechanical stirring and vibration in such harsh working conditions. Long-term stable operation

[0011] In summary, it can be seen that currently, for the three-phase flow catalytic reaction, there is a lack of an ideal high-efficiency production equipment and reaction production method.
