Description
Technical Field
The utility model belongs to the technical field of the chemical reaction heat transfer, especially, relate to a polymerization heat transfer system.
Background
For some polymerization reactions, after the reaction is finished, monomers participating in the polymerization reaction need to be rapidly pumped out of the reactor by vacuum and enter a condenser for heat exchange treatment. For this type of polymerization, the prior art generally employs a conventional tubular heat exchanger or a hybrid condenser for heat exchange treatment.
When the traditional tube type heat exchanger is adopted for processing, a polymer can form a film on the heat exchange surface of the condenser after being cooled, so that the heat exchange performance of the heat exchanger is influenced, and even blockage can occur in severe cases. In addition, the tubular heat exchanger needs larger heat transfer area due to lower heat exchange coefficient, so that the occupied area of equipment is large, and the tubular heat exchanger is easy to scale due to low flow velocity of a tube side and a shell side, has a complex shell side internal structure and is not easy to clean.
When adopting hybrid condenser to handle, can avoid the heat exchange tube wall to form the problem that the tectorial membrane reduces heat exchange efficiency, but this kind of treatment methods can form a large amount of waste water, has increased the waste water treatment degree of difficulty and expense.
