Technical Field
[0001] This application belongs to the field of distributor technology, and specifically relates to a flow distributor. Background Technology
[0002] In related technologies, when liquid is transported from a pipeline to the inside of the equipment, the diameter of the pipeline is relatively small compared to the internal space of the equipment. Due to the small compressibility of the liquid, the large internal space of the equipment directly causes the liquid to rapidly decrease in flow velocity after leaving the outlet of the pipeline, which is not conducive to the rapid distribution of materials. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a flow distributor, which aims to at least partially solve the technical problem of hindering the rapid distribution of materials when liquid is transported from a pipeline into the equipment.
[0004] The technical solution of this utility model is as follows:
[0005] A flow guide distributor includes: at least two distribution members; at least two of the distribution members are partially disposed inside and connected to the material conveying pipe, and at least two of the distribution members are coaxially arranged with the material conveying pipe. Along the radial direction of the material conveying pipe, the projections of two adjacent distribution members on the material conveying pipe at least partially overlap; wherein, along the radial direction of the material conveying pipe, two adjacent distribution members are spaced apart to form a first flow interception channel, and the outermost distribution member located along the radial direction of the material conveying pipe is a first distribution member, and the first distribution member is spaced apart from the inner wall of the material conveying pipe to form a second flow interception channel.
[0006] In some embodiments, the distribution component includes: a cut-off pipe, at least partially disposed within the material conveying pipe; and a guide pipe, communicating with the cut-off pipe and disposed outside the material conveying pipe; wherein, along the direction from the inlet to the outlet of the material conveying pipe, the distance between the inner wall of the guide pipe and the central axis of the material conveying pipe gradually increases.
[0007] In some embodiments, along the axial direction of the material conveying pipe, the inlet of the guide pipe of the first distribution member is spaced apart from the outlet of the material conveying pipe; along the axial direction of the material conveying pipe, the inlets of the guide pipes of two adjacent distribution members are spaced apart.
[0008] In some embodiments, along the direction from the inlet to the outlet of the material conveying pipe, the distance between the inlet of the at least two distribution members' choke pipes and the inlet of the material conveying pipe gradually increases; along the direction from the central axis of the material conveying pipe to the inner wall of the material conveying pipe, the inner diameter of the at least two distribution members' choke pipes gradually increases.
[0009] In some implementations, the inlet walls of the feed ports of at least two of the distribution members are located on the same conical surface.
[0010] In some embodiments, the flow distributor further includes a secondary distribution plate with at least two distribution hole groups; the intercepting pipe, the flow guide pipe, and the secondary distribution plate are arranged sequentially along the direction from the inlet of the material conveying pipe to the outlet of the material conveying pipe; wherein, at least two distribution hole groups are respectively connected to the first intercepting flow channel and the second intercepting flow channel, and the number of distribution holes in each distribution hole group is different.
[0011] In some implementations, the projections of the intercepting pipe and the guiding pipe both fall on the secondary distribution plate in the direction from the inlet to the outlet of the material conveying pipe.
[0012] In some embodiments, the flow distributor further includes a diffuser tube connected to the material conveying pipe; wherein the flow distributor tube is partially disposed within the diffuser tube.
[0013] In some embodiments, the flow distributor further includes a baffle connected to the outlet of a flow guide tube of at least two of the distribution elements that is not the first distribution element; wherein the baffle extends along the central axis of the diffuser tube toward the inner wall of the diffuser tube.
[0014] In some embodiments, the flow distributor further includes a connector for connecting to two adjacent distributors.
[0015] The beneficial effects of this utility model include at least the following:
[0016] Since at least two distribution components are located inside the material conveying pipe, the space inside the material conveying pipe can be fully utilized, reducing the space occupied by the at least two distribution components inside the equipment and improving the utilization rate of the internal space of the equipment.
[0017] Since at least two distribution components are connected to the material conveying pipe, the material conveyed by the material conveying pipe can enter at least two distribution components.
[0018] The projections of two adjacent distribution components on the material conveying pipe overlap at least partially. It can be understood that at least two distribution components are sequentially nested inside the material conveying pipe. Since the two adjacent distribution components are spaced apart along the radial direction of the material conveying pipe to form a first intercepting flow channel, the outermost distribution component located in the radial direction of the material conveying pipe is the first distribution component. The first distribution component is spaced apart from the inner wall of the material conveying pipe to form a second intercepting flow channel. Therefore, when the material enters the material conveying pipe, the material will enter the first intercepting flow channel and the second intercepting flow channel respectively. Along the radial direction of the material conveying pipe, the liquid flow is segmented and intercepted at different flow rates through the first intercepting flow channel and the second intercepting flow channel, and then transported into the equipment.
[0019] Since at least two distribution components are coaxially arranged with the material conveying pipe, the liquid material always flows within the material conveying pipe before entering the equipment, and there is no change in spatial volume. No additional work is required within the at least two distribution components, and the original flow state of the liquid material can still be maintained. Along the flow direction of the liquid material, the resistance of the at least two distribution components is small, and the pressure head loss of the liquid material flow is small. When the liquid material is conveyed into the equipment through the first intercepting flow channel and the second intercepting flow channel, the flow velocity of the liquid material is reduced quickly, so that the liquid material can be distributed quickly. Moreover, the structure of the at least two distribution components is simple, which reduces the pressure difference of the material conveying pipe and eliminates the need to add an inlet pressure release, thereby reducing operating costs.

[0040] This application is described below with reference to the accompanying drawings and specific embodiments:
[0041] The flow distributor provided in this embodiment aims to at least partially solve the technical problem of hindering the rapid distribution of materials when liquid is transported from a pipeline into the equipment.
[0042] Figure 1 These are schematic diagrams of the flow distributors in some embodiments; Figure 2 for Figure 1 Cross-sectional view of the central flow distributor; Figure 3 for Figure 1 Schematic diagram of the working principle of the flow distributor. (Combined with...) Figure 1 , Figure 2 and Figure 3 The flow distributor in this embodiment includes at least two distribution members 10. The at least two distribution members 10 are partially disposed within and connected to the material conveying pipe 20. Both distribution members 10 are coaxially arranged with the material conveying pipe 20. Along the radial direction of the material conveying pipe 20, the projections of adjacent distribution members 10 on the material conveying pipe 20 at least partially overlap. Adjacent distribution members 10 are spaced apart along the radial direction of the material conveying pipe 20 to form a first intercepting flow channel 30. The outermost distribution member 10 located along the radial direction of the material conveying pipe 20 is a first distribution member 11. The first distribution member 11 is spaced apart from the inner wall of the material conveying pipe 20 to form a second intercepting flow channel 40.
[0043] The number of distribution components 10 can be two or more.
[0044] Since at least two distribution components 10 are partially located inside the material conveying pipe 20, the at least two distribution components 10 can make full use of the space inside the material conveying pipe 20, reduce the space occupied by the at least two distribution components 10 inside the equipment, and improve the utilization rate of the internal space of the equipment.
[0045] Since at least two distribution components 10 are connected to the material conveying pipe 20, the material conveyed by the material conveying pipe 20 can enter the at least two distribution components 10.
[0046] The projections of two adjacent distribution members 10 on the material conveying pipe 20 at least partially overlap. It can be understood that at least two distribution members 10 are sequentially nested inside the material conveying pipe 20. Since two adjacent distribution members 10 are spaced apart along the radial direction of the material conveying pipe 20 to form a first intercepting flow channel 30, the outermost distribution member 10 located in the radial direction of the material conveying pipe 20 is the first distribution member 11. The first distribution member 11 is spaced apart from the inner wall of the material conveying pipe 20 to form a second intercepting flow channel 40. Therefore, when the material enters the material conveying pipe 20, the material will enter the first intercepting flow channel 30 and the second intercepting flow channel 40 respectively. Along the radial direction of the material conveying pipe 20, the liquid flow is segmented and intercepted at different flow rates through the first intercepting flow channel 30 and the second intercepting flow channel 40, and then transported into the equipment.
[0047] Since at least two distribution components 10 are coaxially arranged with the material conveying pipe 20, the liquid material always flows within the material conveying pipe 20 before entering the equipment, and there is no change in spatial volume. No additional work is required within the at least two distribution components 10, and the original flow state of the liquid material can still be maintained. Along the flow direction of the liquid material, the resistance of the at least two distribution components 10 is small, and the pressure head loss of the liquid material flow is small. When the liquid material is conveyed into the equipment through the first intercepting channel 30 and the second intercepting channel 40, the flow velocity of the liquid material is reduced quickly, so that the liquid material can be distributed quickly. Moreover, the structure of the at least two distribution components 10 is simple, which reduces the pressure difference of the material conveying pipe 20, eliminates the need to add an inlet pressure release, and reduces operating costs.
[0048] Combination Figure 1 The outermost of the at least two distribution components 10 is the third distribution component 15. The distance between the outlet of the third distribution component 15 and the outlet of the material conveying pipe 20 is L. The occupancy rate of the flow distributor inside the equipment can be adjusted by adjusting the length of L.
[0049] Combination Figure 1 In some embodiments, to achieve material distribution, the distribution component 10 includes a intercepting pipe 12 and a guiding pipe 13. The intercepting pipe 12 is at least partially disposed within the material conveying pipe 20. The guiding pipe 13 communicates with the intercepting pipe 12 and is disposed outside the material conveying pipe 20. The distance between the inner wall of the guiding pipe 13 and the central axis of the material conveying pipe 20 gradually increases along the direction from the inlet to the outlet of the material conveying pipe 20. The intercepting pipe 12 can be cylindrical, and the guiding pipe 13 can be frustoconical.
[0050] After the material enters the material conveying pipe 20, the intercepting pipes 12 of at least two distribution components 10 cut off the material in the radial direction of the material conveying pipe 20 at different flow rates. The guide pipe 13 performs secondary distribution of the material according to actual production needs, so as to achieve rapid distribution of the material in a very short distance or large-area distribution.
[0051] In some embodiments, along the radial direction of the material conveying pipe 20, the intercepting pipes 12 of two adjacent distribution members 10 are spaced apart to form a first intercepting flow channel 30. Along the radial direction of the material conveying pipe 20, the outermost distribution member 10 among at least two distribution members 10 is a first distribution member 11, and the intercepting pipe 12 of the first distribution member 11 is spaced apart from the inner wall of the material conveying pipe 20 to form a second intercepting flow channel 40.
[0052] Combination Figure 1 , Figure 2 and Figure 3 In some embodiments, there are three distribution members 10, namely a first distribution member 11, a second distribution member 14, and a third distribution member 15. Along the central axis of the material conveying pipe 20 towards the inner wall of the material conveying pipe 20, the third distribution member 15, the second distribution member 14, and the first distribution member 11 are arranged alternately. The second distribution member 14 is at least partially located inside the first distribution member 11, and the third distribution member 15 is at least partially located inside the second distribution member 14. The intercepting pipe of the first distribution member 11 is spaced apart from the inner wall of the material conveying pipe 20 to form a second intercepting flow channel 40. The intercepting pipe of the third distribution member 15 and the intercepting pipe of the second distribution member 14 form a first sub-intercepting flow channel 31. The intercepting pipe of the second distribution member 14 and the intercepting pipe of the first distribution member 11 form a second sub-intercepting flow channel 32. The first sub-intercepting flow channel 31 and the second sub-intercepting flow channel 32 together constitute the first intercepting flow channel 30.
[0053] In some embodiments, the intercepting pipe 12, the guiding pipe 13 and the material conveying pipe 20 are coaxially arranged. Before the liquid material enters the equipment, the liquid material always flows in the material conveying pipe 20 and there will be no change in spatial volume. No additional work is required in the intercepting pipe 12 and the guiding pipe 13 of at least two distribution components 10, and the original flow state can still be maintained. Moreover, the resistance of at least two distribution components 10 arranged along the material flow direction is small and the material flow head loss is small. The material distribution is achieved without changing the flow rate of the liquid in the material conveying pipe 20 or increasing the pipe resistance.
[0054] In some embodiments, when preparing the distribution component 10, the distance between the inner wall of the guide pipe 13 and the central axis of the material conveying pipe 20 can be adjusted according to the distribution requirements of different areas and ranges of the equipment. In this way, the angle between the guide pipe 13 and the central axis of the material conveying pipe 20 can be adjusted to ensure that the distribution component 10 can distribute the material according to the distribution requirements of different areas and ranges of the equipment.
[0055] Combination Figure 1 In some embodiments, to achieve the distribution function requirements of the distributor, the inlet of the guide pipe 13 of the first distributor 11 and the outlet of the material conveying pipe 20 are spaced apart along the axial direction of the material conveying pipe 20. The inlets of the guide pipes 13 of two adjacent distributors 10 are also spaced apart along the axial direction of the material conveying pipe 20 to ensure that the material at the connection between the intercepting pipe 12 and the guide pipe 13 maintains the necessary flow rate. This maintains the flow rate of the material in the first intercepting channel 30 and the second intercepting channel 40, reduces material flow head loss, and achieves material distribution.
[0056] Combination Figure 1 In some embodiments, when the distribution member 10 is a first distribution member 11, a second distribution member 14, and a third distribution member 15, the inner diameter of the intercepting pipe of the first distribution member 11 is D1, the inner diameter of the intercepting pipe of the second distribution member 14 is D2, and the inner diameter of the intercepting pipe of the third distribution member 15 is D3.
[0057] To maintain the flow velocity of the material liquid in the second intercepting channel 40 and reduce the head loss of the material liquid flow, the distance between the inlet of the guide pipe of the first distributor 11 and the outlet of the material conveying pipe 20 is H1, and the flow cross-sectional area of the second intercepting channel 40 is A1 = π × D1 × H1. To maintain the flow velocity of the material liquid in the second sub-intercepting channel 32 and reduce the head loss of the material liquid flow, the distance between the inlet of the guide pipe of the second distributor 14 and the inlet of the guide pipe of the first distributor 11 is H2, and the flow cross-sectional area of the second intercepting channel 40 is A2 = π × D2 × H2. To maintain the flow velocity of the material liquid in the first sub-intercepting channel 31 and reduce the head loss of the material liquid flow, the distance between the inlet of the guide pipe of the third distributor 15 and the inlet of the guide pipe of the second distributor 14 is H3, and the flow cross-sectional area of the second intercepting channel 40 is A3 = π × D3 × H3.
[0058] In some embodiments, if the flow distributor has special distribution requirements, by adjusting the sizes of H1, H2 and H3, the material at the connection between the intercepting pipe 12 and the flow guiding pipe 13 can still maintain the necessary flow rate to achieve the distribution function requirements of the flow distributor.
[0059] Combination Figure 1In some embodiments, to ensure that the flow velocity of the material in the first intercepting channel 30 and the second intercepting channel 40 is as uniform as possible, the distance between the inlet of the intercepting pipe 12 of at least two distribution members 10 and the inlet of the material conveying pipe 20 gradually increases along the direction from the inlet to the outlet of the material conveying pipe 20. Along the central axis of the material conveying pipe 20 towards the inner wall of the material conveying pipe 20, the inner diameter of the intercepting pipe 12 of at least two distribution members 10 gradually increases, which can reduce the flow velocity in the first intercepting channel 30 and increase the flow velocity in the second intercepting channel 40, making the flow velocity of the material in the first intercepting channel 30 and the second intercepting channel 40 as uniform as possible, thus achieving rapid material distribution.
[0060] Combination Figure 1 In some embodiments, the inlet walls of the feed ports of the intercepting pipes 12 of at least two distribution members 10 are located on the same conical surface, which can make the flow velocity of the material in the first intercepting channel 30 and the flow velocity of the material in the second intercepting channel 40 as uniform as possible, thereby achieving rapid material distribution.
[0061] Figure 4 for Figure 1 A schematic diagram of the first application of the flow distributor; Figure 5 for Figure 4 Top view of the central flow distributor. (Combined with...) Figure 4 and Figure 5 In some embodiments, to achieve rapid and uniform distribution of liquid across the entire inner cross-section of the vertical container, the flow distributor further includes a secondary distribution plate 50 with at least two distribution hole groups 51. Along the direction from the inlet to the outlet of the material conveying pipe 20, the intercepting pipe 12, the guide pipe 13, and the secondary distribution plate 50 are arranged sequentially. At least two distribution hole groups 51 are respectively connected to the first intercepting channel 30 and the second intercepting channel 40. The number of distribution holes in each distribution hole group 51 is different. After the material enters the material conveying pipe 20, it is distributed by at least two distribution members 10, rapidly and uniformly distributing the liquid to the lower part of the secondary distribution plate 50, achieving a large-area distribution effect in a small pipe opening. The at least two distribution hole groups 51 further distribute the material within the corresponding first intercepting channel 30 and second intercepting channel 40, enabling the material to be rapidly and uniformly distributed across the entire inner cross-section of the equipment. The secondary distribution plate 50 is arc-shaped.
[0062] Combination Figure 4In some embodiments, when the distribution component 10 consists of a first distribution component 11, a second distribution component 14, and a third distribution component 15, the angle between the guide pipe of the third distribution component 15 and the central axis of the material conveying component 20 is angle 1; the angle between the guide pipe of the second distribution component 14 and the guide pipe of the third distribution component 15 is angle 2; the angle between the guide pipe of the second distribution component 14 and the guide pipe of the first distribution component 11 is angle 3; and the angle between the guide pipe of the second distribution component 14 and the inner wall of the equipment is angle 4. Based on the flow rate of the material in the material conveying pipe 20 and the number of distribution holes in the distribution hole group 51, angles 1, 2, 3, and 4 are adjusted to quickly and evenly distribute the material to the lower part of the secondary distribution plate 3, achieving the effect of large-area distribution through small openings.
[0063] In some embodiments, in order to protect the distributor 10, the projections of the intercepting pipe 12 and the guide pipe 13 fall on the secondary distribution plate 50 in the direction from the inlet of the material conveying pipe 20 to the outlet of the material conveying pipe 20. That is, the secondary distribution plate 3 can serve as a protective cover for the guide distributor to avoid the influence of material changes inside the equipment on the guide distributor.
[0064] According to relevant technical standards, the liquid flow velocity inside the diffuser 60 at the inlet of the internal floating roof should not exceed 1 m / s. In actual production, the material flow velocity inside the material conveying pipe 20 is very high, usually 2 to 4 m / s. In order to reduce the material flow velocity, a diffuser 60 is installed inside the material conveying pipe 20. The greater the material liquid flow velocity, the longer the inner extension length of the diffuser 60 needs to be. The weight of the diffuser 60 will generate a greater additional bending moment on the equipment, which is not conducive to the safety of the equipment. Moreover, the longer the diffuser 60 is, the higher the investment cost.
[0065] Figure 6 for Figure 1 A schematic diagram of the second application of the flow distributor. (Combined with...) Figure 6 The flow distributor also includes a diffuser 60, which is connected to the material conveying pipe 20. A portion of the guide pipe 13 is located within the diffuser 60. Adjusting the distance between the guide pipe 13 and the central axis of the material conveying pipe 20 allows for adjustment of the angle of the guide pipe 13, enabling rapid diffusion of the liquid material. This eliminates the need for the diffuser 60 to extend into the material conveying pipe 20, reducing the additional bending moment caused by the weight of the diffuser 60 and improving equipment safety. Furthermore, it reduces the length of the diffuser 60, lowering costs. The distributor 10 is located within the diameter-changing section between the material conveying pipe 20 and the diffuser 60.
[0066] Combination Figure 6In some embodiments, to further reduce the required length of the diffuser tube 60, the flow distributor further includes a baffle 70. The baffle 70 is connected to the outlet of the flow tube 13 of at least two of the distributors 10 that are not the first distributor 11. The baffle 70 extends along the central axis of the diffuser tube 60 toward the inner wall of the diffuser tube 60.
[0067] Since the baffle 70 extends along the central axis of the diffuser 60 towards the inner wall of the diffuser 60, it can be understood that the baffle 70 is perpendicular to the inner wall of the diffuser 60. This causes the material flowing out of the outlet of the guide pipe 13 to not only flow along the axial direction of the diffuser 60, but also to flow in the radial direction of the diffuser 60. The two mutually perpendicular material flows will mix, causing the flow velocity of the material entering the diffuser 660 to drop rapidly, reducing the required length of the diffuser 60, lowering investment costs, and improving the safety of the equipment.
[0068] In some embodiments, when the distributor 10 consists of a first distributor 11, a second distributor 14, and a third distributor 15, the first distributor 11 does not have a baffle 70 to avoid the baffle 70 reducing the distance between the first distributor 11 and the inner wall of the diffuser 60, thus ensuring the stability of the material flow. The second distributor 14 and the third distributor 15 are provided with baffles 70.
[0069] Combination Figure 1 In some embodiments, for the stability of the arrangement of at least two distribution members 10, the flow distributor further includes a connector 80. The connector 80 is connected to two adjacent distribution members 10, thereby realizing the connection between the two adjacent distribution members 10.
[0070] In some embodiments, the connector 80 is connected to the guide pipes 13 of two adjacent distribution members 10 to avoid the connector 80 occupying the flow cross-sectional area of the first intercepting flow channel 30 and the second intercepting flow channel 40.
