Description

Technical Field

[0001] The utility model relates to the technical field of tubular reactors, in particular to a tubular reactor for oxidation reactions. Background Art

[0002] With the rapid development of the chemical industry, oxidation reaction is a key step in chemical synthesis, and the design and optimization of its reactor is particularly important. When performing oxidation reaction operations, traditional oxidation reactors, such as kettle reactors and stirred reactors, have met production needs to a certain extent, but there are still many shortcomings when processing high-viscosity and high-concentration materials or performing specific reactions. Tubular reactors for oxidation reactions have become an important research direction in the current chemical industry to improve reaction efficiency, optimize the reaction environment, and reduce energy consumption.

[0003] At present, the preferred container for oxidation reaction is a tubular reactor. There are many types of tubular reactors on the market. However, most tubular reactors are difficult to be used with large external stirring components for stirring, such as common stirring motors and stirring blades, due to their relatively small inner diameter. The stirring motor and stirring blades cannot be assembled normally, which will cause the lack of corresponding stirring components on such tubular reactors, which is not conducive to promoting the full mixing of raw materials, and will affect the oxidation reaction effect of the materials, causing inconvenience to users. In view of this, we propose a tubular reactor for oxidation reaction. Utility Model Content
