High-capacity solid-phase polycondensation device

The invention provides a high-capacity solid-phase polycondensation device, and belongs to the technical field of preparation or chemical processing of terephthalate polymer compounds. The high-capacity solid-phase polycondensation device comprises a crystallizer, a ridge reaction section and a plurality of filling reaction sections; to-be-treated raw material slices enter the crystallizer to be crystallized; an outlet of the crystallizer communicates with the ridge reaction section; and the ridge reaction section and the multiple filling reaction sections are of an integrated communicating structure. According to the high-capacity solid-phase polycondensation device, high-capacity uniform viscosifying of the slices can be achieved. 本申请提供种大容量固相缩聚装置，属于对苯二酸酯类高分子化合物的制备或化学加工技术领域。包括结晶器、屋脊反应段和多个填充反应段，待处理原料切片进入结晶器进行结晶，结晶器的出口与屋脊反应段连通，屋脊反应段和多个填充反应段为体式连通结构。该装置可实现切片大容量、均匀增粘。
