Catalytic distillation equipment provided with liquid distributor

Abstract

The invention relates to catalytic distillation equipment provided with a liquid distributor, belonging to the field of chemical devices. A liquid distributor is arranged at the upper part of each catalyst bed layer of a middle reaction section, air riser pipes are arranged at two sides, each air riser pipe is of a space formed by the wall of the catalyst bed layer and a tower body, and the tops of the air riser pipes are higher than the liquid distributors; each liquid distributor comprises a disc surface, and sieve meshes and sieve pipes evenly distributed on the disc surface triangularly, and two adjacent triangles enable the sieve meshes and sieve pipes to be alternated; a bottom support is arranged at the bottom of each catalyst bed layer; and a catalyst is bulkily filled in spaces defined by the liquid distributors, the bottom supports and the catalyst bed layer walls. According to the catalytic distillation equipment provided with the liquid distributor, liquid-phase materials are evenly distributed on the catalyst bed layers, and the utilization efficiency of the catalyst can be improved.

Description

technical field [0001] The invention relates to a catalytic distillation equipment provided with a liquid distributor, which is a new type of equipment for the catalytic distillation process in the petrochemical industry and belongs to the field of chemical equipment. Background technique [0002] Catalytic distillation equipment is based on the exothermic chemical reaction process, and the reactants and products have different boiling points. The two processes of catalytic reaction and separation are coupled in the same device, and the reactants and products are separated while the reaction is in progress. To break the balance of the reaction to complete the reaction, and then achieve a higher reaction conversion rate. Since the heat released by the reaction is used for product separation, the process flow is simplified and energy consumption is reduced. [0003] The catalytic distillation column generally includes three parts: the upper rectification section, the middle r...

Problems solved by technology

Although the catalytic distillation equipment provided by this patent provides an inverted funnel-shaped liquid-phase reaction material conduit above the catalyst bed, which is beneficial to the uniform distribution of the liquid-phase material in the catalyst bed, but because there is no special diversion measure inside the conduit, only by pouring The diversion of the funnel is easy to form a phenomenon that there are too many intermediate materials, while the catalysts on both sides of the bed contact with the reaction materials are too small
