Description

Technical Field

[0001] The utility model relates to the field of devolatilization equipment, in particular to a flow distribution device of a devolatilizer. Background Art

[0002] The flow distribution pipe is a key component in the devolatilization process of high-viscosity fluids, and its design is directly related to the efficiency and effectiveness of the devolatilization. Traditional devolatilizer flow distribution pipes mostly use a simple circular tube structure, with distribution holes on the tube to evenly distribute the fluid to the devolatilization area. However, this design has exposed a series of problems in practical applications, especially for high-viscosity fluids, resulting in unsatisfactory devolatilization results.

[0003] First, the circular tube design restricts the fluid flow during the distribution process, resulting in uneven velocity and flow distribution at the distribution holes. This leads to high fluid concentrations in some areas and low fluid concentrations in others. This uneven fluid distribution not only affects devolatilization efficiency but can also lead to unstable product quality after devolatilization.

[0004] Secondly, the diameter of the flow holes in traditional circular tubes is typically consistent, making it difficult to flexibly adjust according to the actual flow conditions during the devolatilization process. High-viscosity fluids have poor flow properties, resulting in greater flow resistance at the flow holes, which can easily lead to fluid accumulation inside the tubes, further reducing devolatilization efficiency.

[0005] To improve this problem, a solution has been proposed in the prior art to increase the number of flow distribution pipes to improve the devolatilization effect. However, while this approach improves the uniformity of fluid distribution to a certain extent, it also increases the complexity of the equipment and the manufacturing cost. Utility Model Content

[0006] The purpose of the utility model is to solve the above technical problems and provide a flow distribution device for a devolatilizer. The present application aims to improve the structure of the flow distribution device for a devolatilizer.

[0007] A flow distribution device for a devolatilizer includes a flow distribution pipe, a connecting side plate and a flow distribution plate. The side of the flow distribution pipe has a feed port, the flow distribution pipe is provided with a connecting slot, the flow distribution plate is connected to the outer side wall of the flow distribution pipe through the connecting side plate, the flow distribution plate includes a bottom plate and a fin plate, the size of the bottom plate is the same as the width of the flow distribution pipe, and is arranged below the flow distribution pipe, the fin plate is arranged on the side of the bottom plate, the bottom plate and the fin plate are arranged horizontally, so that the fin plate extends to the outside of the flow distribution pipe, a plurality of flow distribution holes are provided on the flow distribution pipe, and the connecting slot connects the feed port and the flow distribution holes.

[0008] According to the flow distribution device of the devolatilizer of the present application, the traditional circular flow distribution tube is improved, and a flow distribution plate is formed under the flow distribution tube, so that the material that needs to be devolatilized entering the flow distribution tube will first flow from the flow distribution tube to the flow distribution plate. The horizontal shape of the flow distribution plate allows the material to flow into the devolatilizer more evenly than the flow distribution tube. The fin plate can increase the flow area relative to a simple circular flow distribution tube, which helps to volatilize unreacted monomers and solvents and reduce the residual monomer content of the product.

[0009] Furthermore, a support tube is included, which is arranged between the distribution tube and the distribution plate to form a distribution space between the distribution tube and the distribution plate. The support tube supports the distribution space to prevent the distribution tube from collapsing, so that materials can flow smoothly on the distribution plate.

[0010] Furthermore, the connecting side plates include two first side plates arranged along the axis of the distribution pipe and second side plates arranged on either side of the distribution pipe. The second side plates are arranged above the fin plate and are welded to the outer wall of the distribution pipe and the first side plates, respectively. The first side plates are welded to the distribution plate, the second side plates, and the outer wall of the distribution pipe, respectively. The distribution device is welded together, which facilitates construction within the devolatilizer, allowing the distribution device to be assembled and formed within the devolatilizer.

[0011] Furthermore, the side edges connecting the side plates and the distribution plate are open, so that the material can flow smoothly to the distribution plate, and when there is more material, the distribution plate can be left out from the opening to prevent the material from accumulating and solidifying on the distribution plate.

[0012] Furthermore, the devolatilizer includes a tank body, and the feed port of the flow distribution pipe extends out of the tank body.

[0013] Furthermore, a fixing column is extended from the top of the tank body into the tank body, and the flow distribution device is welded and fixed to the fixing column, so that the flow distribution plate is horizontally installed in the middle of the tank body.

[0018] A flow distribution device of a devolatilizer of the present invention is described with reference to the accompanying drawings.

[0019] like Figures 1 to 4 The flow distribution device of a devolatilizer shown in the figure includes a flow distribution pipe 1, a connecting side plate 2 and a flow distribution plate 3. The side of the flow distribution pipe 1 has a feed port 11, and a connecting slot 12 is opened on the flow distribution pipe 1. The flow distribution plate 3 is connected to the outer wall of the flow distribution pipe 1 through the connecting side plate 2. The flow distribution plate 3 includes a bottom plate 31 and a fin plate 32. The size of the bottom plate 31 is the same as the width of the flow distribution pipe 1 and is arranged below the flow distribution pipe 1. The fin plate 32 is arranged on the side of the bottom plate 31. The bottom plate 31 and the fin plate 32 are arranged horizontally so that the fin plate 32 extends to the outside of the flow distribution pipe 1. The distribution flow tube 1 is provided with a plurality of distribution flow holes 33, and the connecting slot 12 connects the feed port 11 and the distribution flow holes 33. The traditional circular distribution flow tube 1 is improved, and a distribution flow plate 3 is formed under the distribution flow tube 1, so that the material that needs to be devolatilized entering the distribution flow tube 1 will first flow from the distribution flow tube 1 to the distribution flow plate 3. The horizontal shape of the distribution flow plate 3 allows the material to flow into the devolatilizer more evenly relative to the distribution flow tube 1. The fin plate 32 can increase the distribution flow area relative to the simple circular distribution flow tube 1, which is conducive to the volatilization of unreacted monomers and solvents and reduces the residual monomer content of the product.

[0020] It also includes a support tube 4, which is arranged between the flow distribution tube 1 and the flow distribution plate 3, so that a flow distribution space is formed between the flow distribution tube 1 and the flow distribution plate 3. The flow distribution space is supported by the support tube 4 to prevent the flow distribution tube 1 from collapsing, so that the material can flow smoothly on the flow distribution plate 3.

[0021] The connecting side plate 2 includes two first side plates 21 arranged along the axis of the distribution pipe 1 and second side plates 22 arranged on both sides of the distribution pipe 1. The second side plates 22 are arranged above the fin plate 32. The second side plates 22 are welded to the outer side wall of the distribution pipe 1 and the first side plate 21 respectively. The first side plate 21 is welded to the distribution plate 3, the second side plate 22 and the outer side wall of the distribution pipe 1 respectively. The distribution device is connected as a whole by welding, which can facilitate construction in the devolatilizer, so that the distribution device can be assembled and formed in the devolatilizer.

[0022] The side edges connecting the side plate 2 and the distribution plate 3 are open, so that the material can flow smoothly to the distribution plate 3. When there is more material, the distribution plate 3 can also be left out from the opening to prevent the material from accumulating and solidifying on the distribution plate 3.

[0023] like Figure 4 As shown, the devolatilizer includes a tank body 5 , and the feed port 11 of the flow distribution pipe 1 extends out of the tank body 5 , so that the material to be devolatilized can enter the devolatilizer from the feed port 11 .

[0024] A fixed column 51 extends from the top of the tank body 5 into the tank body 5, and the flow distribution device is welded and fixed to the fixed column 51, so that the flow distribution plate 3 is horizontally mounted in the middle of the tank body 5. After the material enters the devolatilizer from the feed inlet 11, it can flow to the bottom of the tank body 5 under the action of gravity under the flow distribution action of the flow distribution device.
