Stirring device of hydrocarbon derivatives hydrogenation reaction reactor

Abstract

A stirring device of a hydrocarbon derivatives hydrogenation reaction reactor comprises a reactor body, wherein a jacket is arranged outside the reactor body, a speed reducer is arranged on the reactor body, a motor is arranged on the speed reducer, a stirring shaft is arranged in the reactor body, and the stirring shaft is connected with an output shaft of the speed reducer. The stirring device is characterized in that an upper-layer stirring paddle, a middle-layer stirring paddle and a lower-layer stirring paddle are arranged on the stirring shaft, wherein the angle, in the horizontal direction, of each of the upper-layer stirring paddle and the lower-layer stirring paddle is staggered with and forms an included angle being 90 degrees with the angle, in the horizontal direction, of the middle-layer stirring paddle, and each of the stirring paddles comprises a connecting sleeve, the two sides of each connecting sleeve are provided with sheet oblique oar blades, the end part of each oblique oar blade is provided with multi-layer of connecting oar blades, each layer of connecting oar blades comprises a bottom plate, an upper oar blade and a lower oar blade are arranged on each bottom plate, an upper left blade and an upper right blade are arranged on each upper oar blade, and a lower left blade and a lower right blade are arranged on each lower oar blade.

Description

technical field [0001] The invention relates to a stirring device for a reaction kettle, in particular to a stirring device for a hydrogenation reaction reaction kettle of hydrocarbon derivatives. Background technique [0002] Hydrogenation reaction is a common chemical unit operation, widely used in pesticides, medicines, dyes and petrochemicals, such as benzene ring hydrogenation, olefin hydrogenation, etc. For the combined agitator used in the reactor in the previous hydrogenation reaction, the lower layer is axial flow agitation, and the upper layer is radial flow agitation. The combined paddle is easily affected by the ventilation position and ventilation volume, and the large ventilation volume may deteriorate the performance of the catalyst. Suspension effect, resulting in uneven distribution of catalyst; moreover, due to the incompatibility of gas and liquid, and the density difference is very large, hydrogen only gets dispersed and reacted by the combined paddle dur...

Problems solved by technology

But its disadvantages are: since the self-priming agitator has high requirements on the speed, it needs to run at a high speed, generally above 400 rpm, which affects the stability of the device
