Abstract
Description
Technical Field
[0001] This invention belongs to the field of catalytic reaction technology for alkyl glycoside products, specifically relating to a catalyst distributed dispensing reaction device. Background Technology
[0002] In organic synthesis experiments, a certain amount of catalyst is usually added to promote the forward reaction. Conventional methods of adding catalyst include either direct addition during the initial feeding or dropwise addition using a constant-pressure funnel. However, in the production of alkyl glycosides, after the solid mixed fatty alcohol is melted at high temperature, powdered glucose and liquid catalyst are added. On a large scale, due to the high viscosity of the materials, uneven mixing of the catalyst and reactants is prone to occur, leading to excessively high local catalyst concentrations. This affects the product structure, reduces reaction efficiency, and increases production energy consumption. Neither of the above two methods of catalyst addition effectively solves this problem.
[0003] Therefore, it is necessary to explore and solve the problem of uniform distribution of catalysts. Utility Model Content
[0004] To address the aforementioned problems, this invention designs and manufactures a catalyst distributed addition reaction device, which can add catalyst to the reaction system in a decentralized manner. This effectively solves the problem of uneven catalyst addition to high-viscosity semi-solid materials, thereby improving reaction efficiency and reducing energy consumption.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A catalyst distributed addition reaction device includes a reaction vessel 1 and a feeder 2.
[0007] The feeder includes a feed pipe 2-2 and a branch pipe 3 connected together. The bottom end of the feed pipe 2-2 passes through the wall of the reactor 1 and is connected to the branch pipe 3 inside the reactor 1.
[0008] There are several branch pipes 3, each of which is an inverted L-shape. The lower end of each branch pipe 3 is the outlet end, and the upper end of each branch pipe 3 is connected to the bottom end of the feed pipe 2-2 through the same multi-channel connector 4.
[0009] The height of the outlet end of each of the branch pipes 3 is different.
[0010] Furthermore, the feed pipe 2-2 is vertically arranged inside the reactor 1, and the branch pipes 3 are evenly distributed around the feed pipe 2-2 in the circumferential direction.
[0011] Furthermore, there are a total of 4 branch pipes 3, and the distances between the outlet end of the 4 branch pipes 3 and the bottom of the inner cavity of the reactor 1 are 10%H, 30%H, 50%H and 70%H respectively, where H is the total height of the inner cavity of the reactor 1, and the multi-channel connector 4 is a five-way valve.
[0012] Furthermore, a feeding valve 2-5 is also provided on the feeding pipe 2-2.
[0013] Furthermore, the bottom end of the feeding pipe 2-2 has only one feeding port 2-3 on the side. The bottom end of the feeding pipe 2-2 is inserted into the vertical passage of the multi-channel connector 4, and the feeding pipe 2-2 rotates under the drive of the first motor 2-4. The rotation of the feeding pipe 2-2 under the drive of the first motor 2-4 causes the feeding port 2-3 to sequentially connect to each branch pipe 3, thereby enabling the catalyst to be added to different branch pipes separately.
[0014] Furthermore, the inverted L-shape has a 5° angle between its lateral portion and the horizontal direction, while its longitudinal portion is vertical. The angle between the lateral portion and the horizontal direction creates a slope in the lateral portion of the branch pipe, which facilitates catalyst flow.
[0015] Furthermore, the vertical portion of the branch pipe 3 is close to the inner wall of the reactor 1. This close but not completely tight fit to the inner wall of the reactor 1 allows for effective catalyst distribution.
[0016] Furthermore, the reactor 1 is also equipped with a stirring device 1-1, which is driven by a second motor 1-2.
[0017] Furthermore, the feeder 2 also includes a feeding tank 2-1, the outlet of which is connected to the feeding pipe 2-2.
[0018] Furthermore, the feeder 2 also includes a reinforcing ring 5, which clamps the vertical portions of all the branch pipes 3. This is used to fix all the branch pipes.
[0019] This utility model has the following beneficial effects:
[0020] This invention adds a feeder to the existing reactor design. The feeder, through the arrangement of branch pipes, adds catalyst from multiple directions, effectively solving the problem of uneven addition from a single direction, thereby improving reaction efficiency and reducing energy consumption. The feed pipes of this invention can rotate freely inside the reactor under the drive of a first motor. Simultaneously, the outlets of the branch pipes at different heights effectively improve the uniformity of catalyst addition, thus increasing reaction efficiency.
[0021] This invention has a simple structure. During the reaction process, the feeding pipe can be rotated to adjust the connection between the feeding port and the branch pipes in different directions, thereby achieving the effect of adding the catalyst in different directions and dispersing it evenly.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the drawings are for illustrative purposes only and are not drawn to strict scale. In addition, there may be local enlargements or reductions for the sake of convenience of description, and there may be certain omissions for well-known parts.
[0028] like Figure 1-3 As shown, a preferred embodiment of this utility model provides a catalyst distributed addition reaction device, including a reactor 1 and a feeder 2. The feeder includes a feed pipe 2-2 and a branch pipe 3 connected together. The bottom end of the feed pipe 2-2 passes through the wall of the reactor 1 and is connected to the branch pipe 3 inside the reactor 1. There are several branch pipes 3, each of which is an inverted L-shape. The lower end of the branch pipe 3 is the outlet end. The upper end of each branch pipe 3 is connected to the bottom end of the feed pipe 2-2 through the same multi-channel connector 4. The height of the outlet end of each branch pipe 3 is different.
[0029] The feeding pipe 2-2 is vertically arranged inside the reactor 1, and the branch pipes 3 are evenly distributed around the feeding pipe 2-2 in the circumferential direction.
[0030] A feeding valve 2-5 is also provided on the feeding pipe 2-2.
[0031] The bottom end of the feeding pipe 2-2 has only one feeding port 2-3 on the side. The bottom end of the feeding pipe 2-2 is inserted into the vertical passage of the multi-channel connector 4. The feeding pipe 2-2 rotates under the drive of the first motor 2-4. Under the drive of the first motor 2-4, the feeding pipe 2-2 rotates, thereby causing the feeding port 2-3 to connect to each branch pipe 3 in sequence, thus realizing the separate addition of catalyst to different branch pipes.
[0032] The inverted L-shape has a 5° angle between its lateral portion and the horizontal direction, while its longitudinal portion is vertical. The angle between the lateral portion and the horizontal direction creates a slope in the lateral portion of the branch pipe, which facilitates catalyst flow.
[0033] The vertical portion of the branch pipe 3 is close to the inner wall of the reactor 1. This close but not completely tight fit with the inner wall of the reactor 1 allows for effective catalyst distribution.
[0034] The reactor 1 is also equipped with a stirring device 1-1, which is driven by a second motor 1-2.
[0035] The feeder 2 also includes a feed tank 2-1, the outlet of which is connected to the feed pipe 2-2.
[0036] The feeder 2 also includes a reinforcing ring 5, which tightens all the vertical portions of the branch pipes 3. This is used to fix all the branch pipes.
[0037] There are four branch pipes 3 in total. The distances between the outlet ends of the four branch pipes 3 and the bottom of the inner cavity of the reactor 1 are 10%H, 30%H, 50%H, and 70%H, respectively, where H is the total height of the inner cavity of the reactor 1. The multi-channel connector 4 is a five-way valve. Specifically, the height of the inner cavity of the reactor 1 is 1m, the total liquid level is 66cm, and the vertical lengths of the four branch pipes are 15-16cm, 30-32cm, 45-48cm, and 60-64cm, respectively.
[0038] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the application.
