The stirring device of the reaction kettle for the hydrogenation of hydrocarbon derivatives, including the reactor body, the jacket outside the kettle body, the reducer on the kettle body, the motor on the reducer, the stirring shaft in the kettle body, the stirring shaft and the reducer The output shaft is connected, and it is characterized in that: the upper, middle and lower three layers of stirring paddles are set on the stirring shaft, wherein the angles of the upper and lower layers of stirring paddles and the middle layer of the stirring paddles in the horizontal direction are staggered by 90°, and the The agitating paddle includes a connecting sleeve, and the two sides of the connecting sleeve are made with sheet-shaped inclined paddles. The end of the inclined paddle is made with multi-layer connecting paddles. Blade and lower blade, upper blade is shaped on left upper blade and right upper blade, and lower blade is shaped on left lower blade and right lower 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...
