Vinyl chloride polymerization reactor design
Abstract：This paper describes the broad prospects development of PVC. The production of PVC polymerization reactor is the most important. This design is about the general of 50cm3PVC polymerization reactor and the book of directions relates the whole design process. In preface there are some technological claim of the polymerization reactor such as text、operation、trail、post safety and so on. The book of direction generally relates the design computation and strength computation. In the technical computation, there are technical dimension determination of reactor body and jacket, the computation and selection of technological conjugation tube and so on; In the strength computation, there are stress check age of the reactor body and jacket, hydraulic test, opening compensation strength, the choice of being structure, the critical rotational speed of axis, the selection and lifespan computation of the bearing and the design of the shaft, s sealing and so on.
