Multi-line reactor

Abstract

The invention discloses a multi-line plug flow reactor, comprising a shell, a reaction tube bundle, tube plates and end enclosures, wherein the upper end and the lower end of the shell are respectively connected with the tube plates; the reaction tube bundle is arranged in the shell, and comprises multiple reaction tubes, the reaction tubes are arranged in parallel, and the upper end and the lowerend of each reaction tube both penetrate through and are fixedly connected to the tube plates; the upper end and the lower end of the shell are respectively provided with an end enclosure, the end enclosures are connected with the tube plates, each end enclosure is of a cavity structure with openings at the upper and the lower parts, the end enclosures are connected with the tube plates to form amixed cavity, and the mixed cavity is used for filling a filler playing a mixing role and / or a catalysis role. The multi-line reactor has the following beneficial effects that on the one hand, the filler can play a mixing role, so as to uniformly mix incoming materials; on the other hand, the filler can also be prepared from a catalyst, so as to perform a catalysis reaction during mixing, and beconvenient for the mounting, fixing and replacement of the catalyst.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and pharmacy, and in particular relates to a multi-line reactor. Background technique [0002] Reactor equipment commonly used in the field of chemical and pharmaceutical technology includes tubular reactors and tank reactors, etc. Among them, tank reactors are often equipped with stirring devices in the reactor for mixing liquid phase reactants. The conversion rate is low, and the energy consumption and pollution are serious. Due to the high requirements for the purity of products in the chemical and pharmaceutical fields, the commonly used reactor equipment is a continuous flow tube reactor. During the use of the continuous flow tube reactor, some reactants often need solid catalysts to catalyze the reaction. There is no special equipment for the installation and removal of solid catalysts, which is inconvenient to use. In addition, when the reactants flow through the reactor, the re...
