Abstract

The invention provides a high-efficiency polymerization reactor, belonging to the field of chemical industry. The reactor comprises a reactor cylinder body, a guide cylinder, an annularly arranged ring heat pipe, a special deflection baffle, an axial-flow pump and a feed port with special charging. The reactor can solve the problem of uniform and quick heat exchange of a polymerization reaction, changes the heat exchange mode of the traditional reactor, has the advantages of high yield in unit volume, uniform heat exchange, no dead angle low energy consumption, low investment and simple and convenient operation, greatly reduces the size of the reactor by improving the heat exchange efficiency and is applicable to all polymerization processes, in particular to rubber production.

Description

Technical field [0001] The invention belongs to the field of chemical engineering, and specifically relates to a high-efficiency polymerization reactor. Background technique [0002] Butyl rubber is a high value-added chemical product, but its industrialized production technology is one of the most complex varieties in polymer production. The design and manufacturing technology of reactors, the core equipment for industrialized production, is currently only a few. Owned by foreign companies. [0003] The polymerization reaction of butyl rubber has the characteristics of fast reaction speed, low temperature, and easy adhesion of the product. Therefore, the reactor used for the polymerization reaction needs to have the characteristics of large heat exchange area, strong heat removal capacity, and no dead corners. The existing polymerization reactors used in the production of butyl rubber mostly adopt heat exchange tube bundles (with refrigerant in the tube and materials outside) or ...
