Which has a better heat exchange effect: the cooling water coil inside the reactor, the external coil, or the cooler? Low cost?
Does anyone have practical experience? Please help!
Built-in coil, provided it does not affect the internal mixing effect
The inner coil is fine, but it may affect mixing or cause material buildup; in addition, if the coil wall is damaged, the medium could leak out. The outer coil is less reliable, and whether an external cooler is needed depends on whether it’s necessary to remove heat from the material promptly – in cases of reactions, it’s better not to use one
Built-in cooling water coils are used in conjunction with both external coils and coolers; each choice is made for valid reasons. Without specific conditions, it’s impossible to say which option is more suitable; it’s best to describe the operating conditions you want to achieve
Surely, the internal coil design offers better performance and lower costs, but it poses safety risks, is difficult to maintain, and is integrated with the process system; thus, failures can disrupt production, and there is a risk of fluid or material leakage, leading to unpredictable negative consequences
Currently, the existing reactor has built-in cooling water coils, but the heat exchange efficiency is not very good! Modifications are required; some have suggested extending the inner coil inside the lower head, as there is a stirrer inside the reactor! I don’t think the feasibility is high!
For specific details, we can discuss it over the phone!
The reason you mentioned for the poor heat exchange performance could be an insufficient heat exchange area; both the internal and external coils have this drawback of having a relatively small heat exchange area. If an external heat exchanger is used, the heat exchange area can be adjusted according to requirements. However, it may be necessary to increase the power settings. This requires a comprehensive consideration to increase power consumption, improve heat exchange efficiency, and enhance overall performance. ，，
