Regarding the heating of the reactor jacket
Thread Content
The company’s reaction reactors are quite special – both steam and cooling water are required, which makes temperature control challenging. Before turning on the steam to raise the temperature, it’s necessary to drain the water first; if the water isn’t completely drained, the temperature won’t rise. The problem is that there’s no easy way to determine whether the water has been fully drained. Installing a temperature sensor on the drainage pipe isn’t very effective, as the temperature response is slow and delayed. Does anyone have any good suggestions?
It is sufficient to install a drain at the bottom of the reactor jacket or coil; once steam pushes against the water, it will naturally be discharged. Float-type steam traps are more suitable when there is cold water in the system (they have a large diameter and low resistance).
Are the reaction kettles in your company double-coil reaction kettles?
Is the drain valve located next to the steam trap? For steam hydrophobicity issues, turn to me! Let me give you a promise: over 15% energy savings.
There are steam traps, but there is a lot of water in the jacket; as a result, the steam traps drain water too slowly. When the temperature fluctuates, the drainage cannot keep up, so generally, the drainage valve is used to release the water
It’s just a jacket, without coils
This is not just a problem with the drain valve; it’s mainly due to the large volume of water causing drainage issues
Use a larger diameter one or connect another in parallel.
Add a compressed air pipeline/use air pressure
This question is too simple! It was solved very well!
