Aldehyde hydrogenation catalyst reduction device

Abstract

The invention discloses an aldehyde hydrogenation catalyst reduction device. The device comprises a reaction kettle body. The device further comprises a jolting assembly which is used for uniformly jolting and turning over materials; a uniform distribution assembly which is used for uniformly distributing a catalyst material onto the jolting assembly; and a heating assembly which is used for switching a heating function and a heat removing function on the jolting assembly. Through a sliding plate and a partition plate, a catalyst material entering from a feeding opening is evenly scattered to reaction bins along the sliding plate, the broken and caked catalyst material is screened and crushed through a knife rest, so that the number and the type of the material distributed in the reaction bins are uniform and consistent. A telescopic rod is driven by a motor to do reciprocating motion, the reaction bins do jolting motion, and therefore, materials in the reaction bins are uniformly rolled, the catalyst is uniformly reduced, and the reaction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of chemical reaction devices, in particular to an aldehyde hydrogenation catalyst reduction device. Background technique [0002] In chemical engineering, the reduction method of the aldehyde hydrogenation catalyst is to first heat the catalyst in the reaction kettle to melt the catalyst to a certain temperature and change its properties, and finally introduce a reducing gas to complete the reduction of the aldehyde hydrogenation catalyst, so that use again. [0003] Then, in the existing reaction kettle, the heating uniformity of the catalyst is not uniform, and some catalysts do not completely change their properties, resulting in that after the reducing gas is introduced, a part of the catalyst fails to react with the reducing gas, the production efficiency is low, and the heat is not enough. The reducing gas has a certain influence, and in the existing reactor, the aldehyde hydrogenation catalyst cannot...

Problems solved by technology

[0003] Then, in the existing reaction kettle, the heating uniformity of the catalyst is not uniform, and part of the catalyst has not completely changed its properties. After the reducing gas is introduced, there is a part of the catalyst that fails to react with the reducing gas, and the production efficiency is low. The reducing gas has a certain influence, and in the existing reactor, the aldehyde hydrogenation catalyst cannot remove the heat in time, which affects the reduction rate of the reducing gas to the catalyst. Therefore, we propose a reduction device for the aldehyde hydrogenation catalyst
