Abstract

The invention relates to the technical field of reactor equipment, and particularly relates to a heat-preservation type hydrogenation reactor. The heat-preservation type hydrogenation reactor comprises a tank body with a hollow interlayer structure, wherein a steam inlet and a steam outlet which are used for conveying steam to a hollow interlayer are formed in the tank body, a hollow mixing shaft connected with a mixing motor is suspended at the center of the tank body, a gas sucking hole, a gas self-suction paddle and a propelling mixing blade are sequentially and fixedly arranged on the mixing shaft from top to bottom; a feeding hole and a hydrogenation hole are formed in an end cover of the tank body, a discharging hole is formed in the upper-half part of the side wall of the tank body, and a heat-transferring plate is fixedly arranged on the inner wall of the tank body. The heat-preservation type hydrogenation reactor is reasonable in design and relatively small in probability of side reaction; the gas-liquid mixing effect is improved, and the hydrogenation reaction rate is increased.

Description

technical field [0001] The invention relates to the technical field of reactor equipment, in particular to a thermal insulation hydrogenation reactor. Background technique [0002] With the continuous advancement of science and technology, sorbitol, xylitol, maltitol and furfuryl alcohol and other products required by chemical and pharmaceutical industries are produced by continuous hydrogenation method, which is the most core equipment in the production of such products It is a hydrogenation reactor. At present, the hydrogenation reaction carried out in the traditional hydrogenation reactor takes a relatively long time, and as the number of times the catalyst is applied, the time will become longer and longer, the side reactions will be more serious, and many impurities that are difficult to remove will be produced. It is easy to cause catalyst poisoning and increase the production cost. Contents of the invention [0003] The technical problem to be solved by the presen...
