Abstract: In order to discuss the structure, function and manufacturing key technology of gas distributor in fluidized bed reactor, this paper reviewed the basic structure and special characteristics of the distributor of hydrogenation reactor, refinery reactor and olefin polymerization reactor. Based on the review, it expatiates on the structure and manufacturing technology of three kinds of distributor commonly used in olefin polymerization reactors covering the circular flat hood distributor, the funnel-shaped combination distributor and the conical integral distributor. The structure and manufacturing technology includes the main structural features, design methods, precision forming of parts, assembly inspection and precision control of supporting and connecting structures. This can provide reference for the design and manufacture of reactor gas distributors.
