Heat transfer device and composition requirements of jacketed reaction kettle
- Jul 13, 2018 -

In the process of making the jacketed reaction kettle, the part of the kettle body is mainly composed of a cylinder and upper and lower sealing heads, and can effectively provide a space for chemical reaction of materials during use, and the volume is mainly produced by the production capacity. The chemical reaction requirements of the product are determined.


The medium and low pressure cylinders of the  jacketed reaction kettle are usually welded by stainless steel plates. They can also be made of carbon steel or cast steel during operation. In order to prevent corrosion of materials during operation, they can be carbon to some extent. The inner surface of steel and cast steel is lining corrosion-resistant material. The shell body can withstand the internal medium pressure and the jacket pressure at the same time. It must be considered according to the situation of internal and external pressure separately, and the strength and stability are calculated separately. A thin-walled cylinder with a large external pressure is provided with a reinforcing ring on the outer surface of the cylinder.


The heat transfer device of the jacketed reaction kettle can be used to timely transfer the heat required for the chemical discharge or the heat discharged from the chemical discharge during operation, and the heat transfer device can be disposed outside or inside the kettle body during the operation. In this way, the temperature can be controlled within the required range. The commonly used heat transfer device is to provide a jacket outside the kettle body or a coil inside the kettle body.


The stirring device of the jacketed reaction kettle is composed of a stirring shaft and a stirrer, so that the materials can be uniformly mixed and contacted, and the chemical reaction is accelerated. During the stirring process, the degree of turbulence of the material increases, and the contact between the reactant molecules and the reactant molecules and the vessel wall is continuously updated, which not only enhances mass transfer and heat transfer, but also facilitates chemical reaction.
