Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of distillation towers, in particular to a catalytic distillation tower reactor. Background Art
[0002] The catalytic distillation tower reactor is a special chemical reaction equipment. It loads the solid catalyst in a proper form into the distillation tower, so that the catalytic reaction and distillation separation can be carried out continuously in the same tower. This design uses the coupling of separation and reaction to enhance the reaction and separation, and is a novel and efficient process method.
[0003] A Chinese patent discloses a catalytic distillation tower reactor (authorization announcement number CN217856053U). The patented technology is provided with a feeding assembly inside a packing cover. The catalyst is transferred from a feed plate to a feed plate. A spring seat is installed at the rear end of the feed plate. When the feed plate is affected by the gravity of the catalyst, the spring seat of the feed plate will shrink, and the feed plate can be forced to move downward and open. Finally, the catalyst is transported from the feed plate to the tower body. The catalyst can be quantitatively filled. A splash-proof frame is provided at the top of the feed plate to effectively prevent the catalyst from splashing. The patented technology is simple to use and effectively brings practicality and convenience to users.
[0004] However, most of the existing tower bodies use a feed plate to guide the feed when feeding, and the solid catalyst cannot be crushed and ground, resulting in large pieces of solid catalyst entering the tower body and affecting the catalytic reaction. For example, the above-mentioned reference document uses a feed plate to feed. In actual application, when the solid catalyst is large and enters the tower body, its reaction catalysis efficiency is slow. Therefore, those skilled in the art provide a catalytic distillation tower reactor to solve the problems raised in the above background technology. Utility Model Content
