Embodiment 1
[0020] Embodiment 1, a multi-line reactor, is characterized in that it includes a shell 1, a reaction tube group 2, a tube sheet 3 and a head 4, and the upper and lower ends of the shell 1 are respectively connected with the tube sheets 3.
[0021] The housing 1 is provided with a reaction tube group 2, the reaction tube group 2 includes a plurality of reaction tubes 20, the reaction tubes 20 are straight tubes arranged in parallel, and the upper and lower ends of each reaction tube 20 pass through and are fixedly connected On the tube sheet 3 and communicated with the mixing chamber 43.
[0022] The upper and lower ends of the housing 1 are all provided with a head 4, and the head 4 is connected with the tube sheet 3, such as image 3 As shown, specifically, the lower end of the head 4 is provided with a connecting flange 42, which is connected to the tube sheet 3 through the connecting flange 42. The head 4 is a cavity structure with upper and lower openings, and is connecte...
Embodiment 2
[0029] Example 2, such as figure 2 As shown, the reaction tube 20 is a helically wound tube with a certain helix angle, which can slow down the speed of the reactants passing through the reaction tube 20, make the rotary cutting rise, mix more uniformly, and react more fully.
[0030] Such as figure 1 , 2 As shown, the lower and upper parts of the housing 1 are respectively provided with a shell-side inlet 10 and a shell-side outlet 11, the temperature-controlled liquid enters through the shell-side inlet 10, is discharged from the shell-side outlet 11, and passes through the outer wall of the reaction tube 20 in the middle , adjust the temperature of the reaction tube 20 to ensure the temperature required for the reaction of the reactants, and improve the adequacy and stability of the reaction.

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...
