Abstract
Description
Technical Field
[0001] This disclosure relates to the field of fluid mixing technology, and more specifically, to a mixing device. Background Technology
[0002] Currently, a common method to mix two fluid streams into one is to install a tee at the point of fluid mixing, for example, refer to... Figure 1 As shown, a conventional tee includes a main pipe 1' and a branch pipe 3' that are interconnected. The first fluid 01' in the branch pipe 3' mixes with the second fluid 02' in the upstream section of the main pipe 1' to form a third fluid 03'.
[0003] In related technologies, when the two fluids being mixed have significantly different states, such as a large difference in temperature and pressure, or when two gas-liquid two-phase fluids are mixed, the use of current tees to directly mix these two fluids will result in a strong exchange of momentum and energy. This will cause stress, thermal stress, and corrosion stress caused by internal pressure to be superimposed, resulting in the main pipeline in the tee bearing a large stress load and erosion corrosion, leading to the risk of leakage. Summary of the Invention
[0004] The purpose of this disclosure is to provide a mixing device that can reduce the stress load and erosion corrosion on the main pipeline, thereby avoiding the risk of leakage.
[0005] To achieve the above objectives, this disclosure provides a mixing device including a main pipeline, a branch pipeline, and a sub-pipeline. The branch pipeline is at least partially disposed in the main pipeline, and the outer wall of the branch pipeline is spaced apart from the inner wall of the main pipeline. The branch pipeline has a first inlet disposed in the main pipeline and communicating with the main pipeline. The sub-pipeline includes a guide pipe, which has a second inlet and a second outlet. The second inlet is disposed outside the main pipeline, and the guide pipe extends into the branch pipeline, with the second outlet located inside the branch pipeline.
[0006] Optionally, the diversion pipe extends along a preset direction, and the diversion pipe is provided with a first inlet and a first outlet on both sides of the preset direction, with the second outlet facing the first outlet.
[0007] Optionally, the medium outflow direction of the second outlet is parallel to the preset direction.
[0008] Optionally, the diversion pipe has a first pipe section and a second pipe section that are interconnected, the central axis of the first pipe section is perpendicular to the central axis of the diversion pipe, the second pipe section is disposed in the diversion pipe, wherein the second pipe section is constructed as a bend and has the second outlet.
[0009] Optionally, the angle between the medium outflow direction of the second outlet and the preset direction is acute.
[0010] Optionally, the first outlet is located in the main pipeline.
[0011] Optionally, the branch pipeline further includes a base pipe connected to the main pipeline and having an inlet, and a guide pipe passing through the base pipe, the guide pipe also having a radial flange that closes the inlet.
[0012] Optionally, the mixing device further includes a support member, wherein the support member is provided between each of the radial sides of the diversion pipe and the main pipeline.
[0013] Optionally, the two supports are staggered in the extension direction of the diversion pipe, and the guide pipe is provided between the two supports.
[0014] Through the above technical solution, in the mixing device provided in this disclosure, when the mixing device is used to mix the first fluid and the second fluid, the second fluid can be injected into the main pipeline. At this time, the second fluid enters from the main pipeline and is divided by the diversion pipe to form an external second fluid located outside the diversion pipe and an internal second fluid located inside the diversion pipe. The first fluid enters the guide pipe through the second inlet and flows into the diversion pipe from the second outlet by injection, and mixes with the second fluid in the diversion pipe to form a fourth fluid. After that, the fourth fluid flows out of the diversion pipe and mixes with the external second fluid again to finally form a third fluid. That is to say, the first fluid and the second fluid are mixed twice in the mixing device to form the third fluid. In this process, because a diversion pipe is installed, and the first fluid in the guide pipe is injected into the diversion pipe rather than directly into the main pipeline, the mixing of the first and second fluids mainly occurs within the diversion pipe. Therefore, this design allows most of the momentum and energy exchange to occur inside the diversion pipe, ensuring that the fourth fluid, when flowing out of the diversion pipe, has a relatively stable flow state. This reduces the stress load and erosion corrosion on the main pipeline, avoiding the risk of leakage. Furthermore, compared to the direct mixing of the first and second fluids in related technologies, the secondary mixing method of the mixing device disclosed herein further reduces the momentum and energy exchange during mixing, further preventing leakage risks. Moreover, since most of the momentum and energy exchange occurs inside the diversion pipe, the mixing device disclosed herein can adapt to mixing first and second fluids with significant differences in fluid states, such as significant differences in temperature and pressure, or one of the first and second fluids being a gas phase and the other a liquid phase. Therefore, the mixing device disclosed herein also has the advantage of good applicability.
[0015] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0025] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours of each component itself. The terms "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same or similar elements, which this disclosure will not elaborate upon.
[0026] refer to Figure 1As shown, in the related technology, when using a tee to mix the first fluid 01' and the second fluid 02', the first fluid 01' in the branch pipe 3' mixes with the second fluid 02' in the upstream section of the main pipe 1' to form the third fluid 03'. That is, in the related technology, the first fluid 01' and the second fluid 02' in the tee are directly mixed, while the third fluid 03' is formed through a single mixing process. The drawback of this design is that it easily leads to the main pipe 1' being subjected to large stress loads and erosion corrosion, causing a risk of leakage.
[0027] Therefore, this disclosure provides a mixing device, with reference to Figures 2 to 4 As shown, the mixing device includes a main pipeline 1, a branch pipeline 2, and a branch pipeline 3. The branch pipeline 2 is at least partially disposed in the main pipeline 1, and the outer wall of the branch pipeline 2 is spaced apart from the inner wall of the main pipeline 1. The branch pipeline 2 has a first inlet 21 disposed in the main pipeline 1 and communicating with the main pipeline 1. The branch pipeline 3 includes a guide pipe 31, which has a second inlet 311 and a second outlet 312. The second inlet 311 is disposed on the outside of the main pipeline 1, and the guide pipe 31 extends into the branch pipeline 2, with the second outlet 312 located inside the branch pipeline 2.
[0028] Through the above technical solution, in the mixing device provided in this disclosure, when the mixing device is used to mix the first fluid 01 and the second fluid 02, the second fluid 02 can be injected into the main pipeline 1. At this time, the second fluid 02 enters from the main pipeline 1 and is divided by the diversion pipe 2 to form an external second fluid 02 located outside the diversion pipe 2 and an internal second fluid 02 located inside the diversion pipe 2. The first fluid 01 enters the guide pipe 31 through the second inlet 311 and flows into the diversion pipe 2 from the second outlet 312 by injection. It mixes with the second fluid 02 in the diversion pipe 2 to form a fourth fluid 04. After that, the fourth fluid 04 flows out of the diversion pipe 2 and mixes with the external second fluid 02 again to finally form a third fluid 03. That is to say, the first fluid 01 and the second fluid 02 are mixed twice in the mixing device to form the third fluid 03. In this process, because a diversion pipe 2 is provided, and the first fluid 01 in the guide pipe 31 is injected into the diversion pipe 2 rather than directly into the main pipeline 1, the mixing of the first fluid 01 and the second fluid 02 mainly occurs in the diversion pipe 2. Therefore, this design allows most of the momentum and energy exchange to occur inside the diversion pipe 2, so that the flow state of the fourth fluid 04 formed is already relatively stable when it flows out of the diversion pipe 2. This reduces the stress load and erosion corrosion on the main pipeline 1, avoiding the risk of leakage. In addition, compared with the method of directly mixing the first fluid 01 and the second fluid 02 in related technologies, the secondary mixing method of the mixing device disclosed in this invention can further reduce the momentum and energy exchange that occurs during mixing, further avoiding the risk of leakage. Furthermore, since most of the momentum and energy exchange occurs inside the splitter tube 2, the mixing device of this disclosure can be adapted to the mixing of a first fluid 01 and a second fluid 02 with significant differences in fluid states. For example, the temperature and pressure values of the first fluid 01 and the second fluid 02 may differ significantly, or one of the first fluid 01 and the second fluid 02 may be in a gas phase and the other in a liquid phase. Therefore, the mixing device of this disclosure also has the advantage of good applicability.
[0029] It should be noted that the reference Figure 2 and Figure 4 As shown, the main pipeline 1 may have a third inlet 11 and a third outlet 12. In use, the second fluid 02 can enter the main pipeline 1 through the third inlet 11, and the third fluid 03 formed after mixing can flow out of the main pipeline 1 through the third outlet 12.
[0030] In an exemplary embodiment of this disclosure, reference is made to Figures 2 to 4As shown, the first outlet 22 can be located in the main pipeline 1, so that the mixing of the fourth fluid 04 and the second fluid 02 can occur inside the main pipeline 1. Thus, when the fourth fluid 04 mixes with the external second fluid 02 to form the third fluid 03, only a small portion of the momentum and energy exchange acts on the main pipeline 1, thereby increasing the service life of the main pipeline 1.
[0031] In an exemplary embodiment of this disclosure, reference is made to Figures 2 to 4 As shown, the diversion pipe 2 extends along a preset direction, and the diversion pipe 2 is provided with a first inlet 21 and a first outlet 22 on both sides of the preset direction. The second outlet 312 can be set towards the first outlet 22. In this way, the first fluid 01 flowing out through the second outlet 312 can flow towards the first outlet 22, avoiding the backflow phenomenon when the second outlet 312 is set towards the first outlet 22, and increasing the momentum and energy exchange that occurs when the first fluid 01 and the second fluid 02 mix in the diversion pipe 2.
[0032] In some embodiments of this disclosure, reference is made to Figure 4 As shown, the medium outflow direction of the second outlet 312 can be parallel to a preset direction. In this way, the flow direction of the first fluid 01 flowing out of the second outlet 312 can be the same as the flow direction of the second fluid 02 in the diversion pipe 2. This can further reduce momentum exchange, thereby making the mixing process of the first fluid 01 and the second fluid 02 in the diversion pipe 2 smoother and more stable.
[0033] In some embodiments of this disclosure, reference is made to Figure 4 As shown, the guide pipe 31 may have a first pipe section 313 and a second pipe section 314 that are interconnected. The central axis of the first pipe section 313 is perpendicular to the central axis of the branch pipe 2. The second pipe section 314 is disposed in the branch pipe 2, and the second pipe section 314 may be constructed as a bend and have a second outlet 312. Here, since the central axis of the first pipe section 313 is perpendicular to the central axis of the branch pipe 2, by designing the second pipe section 314 as a bend, it is easy to arrange the medium flow direction of the second outlet 312 parallel to a preset direction, resulting in a simple structure that is easy to implement. Here, refer to... Figure 4 As shown, the end of the bend can extend in a preset direction so that the medium flow direction of the second outlet 312 is arranged parallel to the preset direction, and this disclosure does not limit this.
[0034] In other embodiments of this disclosure, reference is made to Figure 2 and Figure 3 As shown, the medium outflow direction of the second outlet 312 can form an acute angle with the preset direction. For example, in some embodiments, the medium outflow direction of the second outlet 312 can form an angle of 30° or 45° with the preset direction, and this disclosure does not limit this.
[0035] In an exemplary embodiment of this disclosure, reference is made to Figures 2 to 4 As shown, the branch pipe 3 also includes a base pipe 32, which is connected to the main pipe 1 and has an inlet. A guide pipe 31 passes through the base pipe 32, and the guide pipe 31 also has a radial flange 315 that closes the inlet. Thus, the base pipe 32 and the main pipe 1 can form a tee as described in the related art. By setting the branch pipe 2 and the guide pipe 31 in this tee, a mixing device can be assembled. Therefore, the mixing device of this disclosure also has the characteristics of simple structure and easy assembly. The radial flange 315 can close the inlet to prevent leakage. Of course, in other embodiments, the branch pipe 3 may only include the guide pipe 31. In this case, a clearance hole can be formed on the main pipe 1, and the guide pipe 31 is sealed to the clearance hole.
[0036] In an exemplary embodiment of this disclosure, reference is made to Figure 4 As shown, the mixing device may also include a support 4, with a support 4 provided between each of the radial sides of the diversion pipe 2 and the main pipeline 1. This can increase the stability of the diversion pipe 2, prevent accidental movement or erratic movement of the diversion pipe 2, and the support 4 can also counteract the vibrations generated during power and energy exchange, improving the durability of the mixing device.
[0037] In some embodiments of this disclosure, reference is made to Figure 4 As shown, the two support members 4 are staggered in the extension direction of the diversion pipe 2, and a guide pipe 31 is provided between the two support members 4. This arrangement can further improve the stability of the diversion pipe 2.
[0038] In some embodiments of this disclosure, the support 4 may be constructed as an arc-shaped block, which may fit against the inner wall of the main pipeline 1 and the outer wall of the diversion pipe 2 respectively, so as to further improve the stability of the diversion pipe 2.
[0039] In some embodiments of this disclosure, the central axis of the diversion pipe 2 may be parallel to the center of the main pipeline 1. For example, the central axis of the diversion pipe 2 may coincide with the central axis of the main pipeline 1. This disclosure does not limit this.
[0040] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
[0041] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0042] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
