Kettle type stirring reactor

Abstract

The invention relates to a kettle type stirring reactor. The stirring reactor comprises a kettle body, a stirring shaft arranged in the kettle body, paddles connected to the lower portion of the stirring shaft and a motor arranged on the upper portion of the kettle body and connected with the upper end of the stirring shaft, and a feed port and a discharge port are formed in the kettle body; a hollow barrel-shaped flow guide cover opened in the upper portion and the lower portion is arranged in the kettle body and is fixed in the kettle body through a connecting part, a gap is formed between the flow guide cover and the inner wall of the kettle body, multiple flow guide holes for a material to pass through are formed in the side wall of the flow guide cover, the paddles are arranged in the flow guide cover, and the height of the paddles in the flow guide cover corresponds to the positions of the flow guide holes in the side wall of the flow guide cover. The kettle type stirring reactor has the advantages of being simple in structure and good in effect, stirs the material uniformly and enables the material to react sufficiently.

Description

technical field [0001] The invention relates to the field of chemical tank reactors, in particular to a tank stirred reactor. Background technique [0002] Tank reactors, also known as tank and pot reactors, are mainly used in liquid-liquid homogeneous reaction processes, and are also used in gas-liquid and liquid-liquid heterogeneous reaction processes. In chemical production, it is not only suitable for batch operation process, but also can be used for continuous operation process in single tank or multiple tanks in series. [0003] Stirred tank reactors are often used in the research and application of microbial fermentation, chemical synthesis, etc., and play an important role in modern chemical production. They are suitable for liquid materials or fibrous and crystalline solutions. The stirred tank reactor is composed of a stirrer and a tank body. The materials are mixed and flowed in the reactor, with a large phase contact area, a wide range of applicable temperature ...

AI Technical Summary

Problems solved by technology

The stirred tank reactor is composed of a stirrer and a tank body. The materials are mixed and flowed in the reactor, with a large phase contact area, a wide range of applicable temperature and pressure, strong adaptability, large operating flexibility, and easy temperature concentration during continuous operation. Control and other characteristics, but when there is a high conversion rate process requirement, the existing tank-type stirred reactor is not evenly stirred and the reaction is not complete. If the gas is introduced into the reactor to speed up the mixing and flow of materials in the reactor, it cannot be guaranteed. Whether there is a reaction relationship between the gas and the reaction liquid, and will bring impurities
