Seeking advice on the design of suspended reaction reactors
Thread Content
Recently, my company has been working on new product development, focusing on modifying the molecular structure of polymers. I’ve been finding that the stirring effect in the small test reactor used in my workplace isn’t very good; I would appreciate any advice from those with experience in this area. . .

I’m not sure what shape the mixing blades in your unit are at the moment. You can consider factors such as the mixing speed, as well as the height and shape of the mixing blades.
The shape of the stirrer, the properties of the fluid, and the size of the reactor all affect mixing. To achieve good results, it is advisable to consult a professional stirring equipment manufacturer for design assistance.
Generally, homemade reaction vessels are bare inside; if it doesn’t cause any problems, you can try adding some baffles
Find a company that specializes in mixing to get advice from them
You should consider the desired distribution based on the particle size, degree of polymerization, and other factors you need. Consider the stirring speed as well as the distribution issue.
The impeller is a paddle-type impeller. . . I have been adjusting the stirring speed, height, and shape, but it seems that the stirring effect in the large reactors used for production is not as good. .
Thank you for your attention; a baffle has been added. .
It can be found by searching on Baidu, but the quality varies; be careful when choosing.
Great Wall Mixing – it seems okay. I asked for their advice, and they submitted a proposal within a few days. I’m not a promoter
It is recommended to use simplified three-blade stirrers, with four baffles installed inside the tank; these baffles can be used, together with circulating water, to regulate the temperature within the tank. Stirring can be done using a bottom-extending or top-extending type. It is recommended to use imported mixing reducers, as they offer better performance in terms of speed and quality compared to domestic ones. However, this does not mean that domestic options are unsuitable; the quality of products produced by Jinxi Chemical Machinery Factory is quite good. At the same time, the polish level inside the kettle must be high.
