Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline mixer technology, and in particular to a static mixing device. Background Technology
[0002] A static mixer is a mixing device without moving parts. It mainly uses a mixing unit fixed in a pipe to change the flow state of the fluid, so as to disperse and mix different fluids. At present, static mixers are not only used in mixing processes, but also in processes related to mixing and transfer, including gas-gas mixing, liquid-liquid mixing, gas-liquid mixing, enhanced heat transfer and liquid-liquid reaction processes.
[0003] However, the mixing structure inside most static mixers on the market is a combination of spiral blades or cross-tilted plates, which is complex and difficult to separate. This not only easily causes blockage inside the mixer, but also leads to a significant loss of fluid pressure, reducing the ease of maintenance and practicality of the static mixer. Utility Model Content
[0004] The purpose of this invention is to solve the problems of blockage and large pressure loss caused by the complex structure of existing static mixers, and to propose a static mixing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A static mixing device includes a first pipe, two sets of mounting components arranged sequentially along the fluid flow direction of the first pipe, the projections of the two sets of mounting components on the axis L having a preset distance, and further includes: a second pipe disposed on the first mounting component, wherein the second pipe has a through hole facing the inlet end of the first pipe; and a flow-disrupting component disposed on the second mounting component.
[0007] To improve the mixing effect, preferably, the spoiler includes a first spoiler plate, the first spoiler plate having a first plane, and an axis L passing through the first plane and perpendicular to the first plane.
[0008] Furthermore, both the first spoiler and the second pipe are made of titanium.
[0009] To improve the turbulence effect, preferably, a second turbulence plate is symmetrically arranged on the circumferential surface of the second pipe, and the second turbulence plate has a second plane, with the axis L perpendicular to the second plane.
[0010] Furthermore, the through holes are provided in two rows, and both rows of through holes are located on the same side of the second spoiler.
[0011] Furthermore, the mounting component includes a first branch pipe and a second branch pipe, the axes of the first branch pipe and the second branch pipe being spatially perpendicular.
[0012] Furthermore, the ends of both the first branch pipe and the second branch pipe are fixedly connected to a second flange, wherein the second pipe and the baffle are both fixedly connected to a mounting flange, and the mounting flange is connected to the second flange by bolts.
[0013] Preferably, both ends of the first pipe are fixedly connected to a first flange.
[0014] Compared with the prior art, the present invention provides a static mixing device with the following advantages:
[0015] 1. This static mixing device ensures that the fluid velocity in the second pipe is lower than that in the first pipe by controlling the number of through holes. A second baffle is set behind the through holes of the second pipe, so that the fluid in the second pipe can fully diffuse into the first pipe. After the fluid in the second pipe has fully diffused and mixed with the fluid in the first pipe and flows forward for a certain distance, the horizontally placed first baffle re-disperses the mixed liquid and mixes it again. This improves the mixing efficiency, reduces the complexity of the structure, reduces pressure loss, and improves the flexibility of maintenance.
[0016] 2. This static mixing device, by setting a second pipe and a flow-dispersing element before and after the first pipe, on the one hand, releases the fluid to be mixed in the second pipe to mix with the fluid flowing in the first pipe. On the other hand, by using the structural shape of the second pipe to create a primary flow disturbance for the mixed fluid, the flow-dispersing element, which is set at intervals, can ensure the duration of the primary mixing to promote the fullness of the secondary mixing, prevent the interception of impurities and blockage, and also prevent excessive loss of fluid velocity in the first pipe, thus effectively improving the practicality of static mixing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.
[0024] Example:
[0025] Reference Figures 1-4 A static mixing device includes a first pipe 1 for conveying a first gas or liquid. Both ends of the first pipe 1 are welded with first flanges 10. Two sets of first flanges 10 are connected to equipment or other pipes via bolts through circumferentially equidistant fixing holes for transmission operations. Two sets of mounting components are arranged sequentially in a front-to-back manner along the fluid flow direction of the first pipe 1. The projections of the two sets of mounting components on the axis L of the first pipe 1 are 3-10 cm apart. The device also includes a second pipe 4 for conveying another mixing gas or liquid, mounted on the front mounting component. The second pipe 4 has a through hole 6 for discharging the second gas or liquid, facing the inlet end of the first pipe 1. A flow-dispersing element is mounted on the rear mounting component; that is, when fluid enters the first pipe 1, it first passes through the second pipe 4 and then through the flow-dispersing element.
[0026] In the above design, by setting the second pipe 4 and the flow-dispersing element before and after the first pipe 1, on the one hand, the fluid that needs to be mixed in the second pipe 4 is released to mix with the fluid flowing through the first pipe 1. On the other hand, the structural shape of the second pipe 4 forms a primary flow disturbance to the mixed fluid, while the flow-dispersing element is set at intervals to ensure that the duration of the primary mixing promotes the fullness of the secondary mixing, prevents the interception of impurities and blockage, and also prevents excessive loss of fluid velocity in the first pipe 1, effectively improving the practicality of static mixing.
[0027] Specifically, the turbulence-disrupting component includes a first turbulence-disrupting plate 7, which has a first plane. An axis L passes through the first plane and is perpendicular to the first plane, which can ensure effective mixing of the fluid after the first mixing. In some embodiments, the first plane may also have an inclined angle with the axis L, such as 60° or 75°, which can also ensure effective turbulence mixing.
[0028] Here, positioning blocks are fixedly connected to both sides of one end of the first baffle 7. When it is inserted into the branch pipe, it can fit against the inner wall of the branch pipe, thereby preventing it from shaking when it is impacted by fluid.
[0029] In addition, the first spoiler 7 and the second pipe 4 can be made of pure titanium or related titanium alloys, which can ensure the strength of the structural components while slowing down corrosion.
[0030] In some embodiments, second baffles 5 are symmetrically arranged on the circumferential surface of the second pipe 4, and the second baffles 5 have a second plane, the axis L is perpendicular to the second plane, that is, the second plane is parallel to the first plane, and the width of the second baffles 5 is much smaller than that of the first baffles 7. The two rows of through holes 6 opened on the second pipe 4 are located on the same side of the second baffles 5. At this time, the second baffles 5 have the speed to block the fluid discharged in the through holes 6 from being carried away by the fluid in the first pipe 1, so that the fluid in the first pipe 1 can be fully mixed with the fluid discharged in the through holes 6.
[0031] Here, the axis of the through hole 6 forms a 60° angle with the axis L. The number of through holes 6 is controlled to ensure that the fluid flow rate in the injection pipe is lower than the fluid flow rate in the first pipe 1, so as to further improve the mixing effect.
[0032] Specifically, the mounting components are the first branch pipe 2 and the second branch pipe 3. The two branch pipes are welded to the first pipe 1 and their diameters are much smaller than those of the first pipe 1. In some embodiments, the axes of the first branch pipe 2 and the second branch pipe 3 are perpendicular to each other to improve the mixing effect. Of course, other angles can also be used to ensure secondary mixing.
[0033] A second flange 9 is fixedly connected to the ends of the first branch pipe 2 and the second branch pipe 3. A mounting flange 8 is fixedly connected to the second pipe 4 and the flow-dispersing component. The mounting flange 8 is connected to the second flange 9 by bolts, thereby fixing the second pipe 4 and the flow-dispersing component, ensuring the stability of each structural component when the fluid flows, and the detachable method makes it easy to remove, thereby clearing the first pipe 1. The number of branch pipes and flow-dispersing components can also be increased as needed to improve the mixing effect.
[0034] In this invention, one fluid first flows into the first pipe 1, and the other fluid flows out through the through hole 6 through the second pipe 4. After passing through the second baffles 5 on both sides, the fluid diffuses into the first pipe 1. The two liquids are mixed for the first time in the first pipe 1. After passing through the first baffle 7, they are mixed for the second time, and finally achieve uniform mixing. When the first pipe 1 is blocked, the fixing bolts of the first baffle 7 can be removed and the baffle can be taken out. After maintenance, it can be reinstalled in its original position.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
