A kind of oil hydrogenation reactor

Abstract

The invention belongs to the technical field of grease chemical production and in particular relates to a grease hydrogenation reactor. The grease hydrogenation reactor comprises an upper box body, alower box body, an oil injection unit, a hydrogenation plate and a carrying plate. A circular flange is arranged on the lower end face of the upper box body, a lug is arranged on the outer surface ofthe upper box body for lifting the upper box conveniently, and a hydrogenation pipe is arranged on the upper box body; a circular groove is formed in the upper end face of the lower box body, and theupper box body and the lower box body are connected by matching of the circular flange and the circular groove; the oil injection unit is used for injecting liquid grease; the hydrogenation plate is horizontally fixed in the upper box body, a cavity is formed in the hydrogenation plate, the cavity of the hydrogenation plate communicates to the hydrogenation pipe, an air outlet hole is formed in the bottom face of the hydrogenation plate, the air outlet hole communicates to the cavity in the hydrogenation plate, and the hydrogenation plate is used for injecting hydrogen; and the carrying plateis located in the lower box body, and a reaction cavity is formed between the carrying plate and the hydrogenation plate. The grease hydrogenation reactor provided by the invention enhances the ability of mixing hydrogen into grease and is high in reaction rate.

Description

technical field [0001] The invention belongs to the technical field of oil chemical production, in particular to an oil hydrogenation reactor. Background technique [0002] Hydrogenation of unsaturated oils refers to the process of adding unsaturated animal and vegetable oils with hydrogen under the action of a catalyst to saturate the double bonds or triple bonds contained in the oil molecules. Its function is to reduce the degree of unsaturation of oil, increase the melting point, increase the content of solid fat; improve the stability of oil to oxygen and heat; improve the color, aroma and flavor of oil. In the process of oil hydrogenation reaction, the mixing degree of liquid oil and hydrogen has a very important influence on the reaction rate. The mixing degree of hydrogen and oil increases, and the hydrogenation rate increases accordingly.

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned patent document 1, by arranging the stirring shaft and the paddle in the tank, the hydrogen gas is mixed with the grease through the rotation of the stirring shaft, and the solid grease after hydrogenation is adhered to the stirring shaft due to the existence of the stirring shaft, which is the follow-up solidified grease. The removal and cleaning work brings difficulties and reduces work efficiency
