Continuous stirring polymerizing reactor tower

A continuous stirred polymerization reactor tower, the partition between the upper and lower head of the cold separator baffles into several stages, each stage outer tower section with a cooling jacket, stirring shaft is assembled from segments, each tower segment stirring shaft with two sieve tray, the tower section is divided into three zones, each zone of the agitator shaft are respectively equipped with a stirring paddle. As a result of smaller cross-sectional axial passage of material within the isolation baffle and cooling characteristics of both additional stirring action sieve trays, suppressing material interstage backmixing axial back-mixing, with near plug flow. The present invention is applicable to a large thermal load chemical reactions, inhibiting backmixing material requires a high continuous polymerization process.
