Rotary gas feed distributor suitable for multi-phase reactor

Abstract

The invention discloses a rotary gas feed distributor suitable for a multi-phase reactor. The distributor comprises a main gas inlet pipe, a rotary connector, feed distribution branch pipes, inclined transverse nozzles and longitudinal nozzles. The main gas inlet pipe is located at the center of the distributor, is of a cylindrical structure and perpendicularly penetrates through the whole distributor. The rotary connector is located in the middle of the main gas inlet pipe and can freely rotate. The rotary connector can keep the lower portion of the main gas inlet pipe still, but the upper portion of the main gas inlet pipe can freely rotate. The feed distribution branch pipes are connected and communicated with the upper portion of the main gas inlet pipe. The inclined transverse nozzles and the longitudinal nozzles are located on the feed distribution branch pipes. When the longitudinal nozzles spray out gas, sprayed gas generates lateral counter-acting force to push the feed distribution branch pipes and the upper portion of the main gas inlet pipe to rotate. By means of the distributor, the uniformity of gas distribution can be improved, abrasion to catalysts is reduced, and reaction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a rotary gas feed distributor suitable for multiphase reactors. Background technique [0002] At present, in the slurry bed F-T synthesis reactor, the gas raw material enters the gas distributor from the main inlet pipe. When the inlet pressure is stable, the gas will disperse into the feed distribution pipe and finally pass through the openings on the distribution pipe. Entering the slurry bed reactor, it drives the slurry (liquid and solid catalyst) in the reactor to move and the Fischer-Tropsch synthesis reaction occurs under the action of the catalyst, and the resulting liquid product is filtered and separated to leave the reactor. [0003] However, in the slurry bed F-T synthesis reactor in the prior art, the entire gas distributor is not active, resulting in uneven distribution of raw material gas in the reactor, insufficient mixing of gas and catalyst, resulting...
