Description

Technical Field

[0001] This utility model belongs to the technical field of natural gas vertical static mixers, specifically relating to a natural gas vertical static mixer with filtration function. Background Technology

[0002] A vertical static mixer for natural gas is a highly efficient mixing device commonly used in natural gas processing and transportation. It has no moving parts and relies on mixing units fixed inside the pipe to change the flow state of the fluid, achieving good dispersion and thorough mixing between different fluids. When fluids such as natural gas flow in the pipeline, they impact various plate elements. In laminar flow, this increases the velocity gradient of the fluid, causing the fluid to undergo a process of "splitting - repositioning - re-merging." In turbulent flow, in addition to the above three situations, intense eddies are formed in the cross-sectional direction. These eddies generate strong shear forces that act on the fluid, further dividing and mixing it, ultimately forming a homogeneous mixture.

[0003] Currently, existing vertical static mixers for natural gas typically use internal mixing units to alter the flow of fluids, enabling thorough mixing between different fluids. However, traditional vertical static mixers for natural gas usually lack filtration capabilities. Therefore, when natural gas containing impurities enters the vertical static mixer, it mixes with the impurities. These impurities mixed in the natural gas may cause wear and tear on the vertical static mixer during its flow, thus reducing its service life. Furthermore, the natural gas mixed with impurities can interfere with the mixing process, thereby reducing the uniformity and stability of the gas. Utility Model Content

[0004] The purpose of this invention is to provide a vertical static mixer for natural gas with a filtration function. This addresses the problem that existing vertical static mixers for natural gas typically rely on internal mixing units to alter fluid flow and ensure thorough mixing of different fluids. However, traditional vertical static mixers for natural gas usually lack filtration capabilities. Therefore, when natural gas containing impurities enters the mixer, it mixes with the impurities. These impurities mixed in the natural gas can cause wear and tear on the mixer during flow, reducing its lifespan. Furthermore, the mixed impurities can interfere with the mixing process, thus reducing the uniformity and stability of the gas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical static mixer for natural gas with filtration function, comprising a vertical static mixer shell, a mixing unit installed inside the vertical static mixer shell, a connecting flange fixedly connected to the end of the vertical static mixer shell, and two positioning grooves formed on the surface of the connecting flange;

[0006] The positioning groove has a limit slot inside. A connecting frame is installed on the top inner side of the vertical static mixer shell.

[0012] As a preferred embodiment of the present invention, a vertical static mixer for natural gas with filtration function is provided, wherein an annular sealing ring is bonded to the inside of the annular groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By moving the movable block with the toggle, the limit pin retracts. Then, the connecting frame and filter element are placed into the housing of the vertical static mixer from the top, and the mounting base is embedded in the positioning groove. At this time, by releasing the toggle, the limit pin can be ejected under the action of the return spring and inserted into the limit slot, thereby installing the filter element on the top of the housing of the vertical static mixer.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4The present invention provides the following technical solution: a vertical static mixer for natural gas with filtration function, including a vertical static mixer shell 1, a mixing unit 2 installed inside the vertical static mixer shell 1, a connecting flange 3 fixedly connected to the end of the vertical static mixer shell 1, and two positioning grooves 4 opened on the surface of the connecting flange 3.

[0024] The positioning groove 4 has a limit slot 5 inside. A connecting frame 6 is installed on the top of the inner side of the vertical static mixer shell 1. A filter element 7 is connected to the bottom of the connecting frame 6. Two mounting seats 8 are fixedly connected to the outer wall of the connecting frame 6. A return spring 9 is movably connected inside the mounting seat 8. A movable block 10 is connected to the end of the return spring 9. A limit pin 11 is fixedly connected to one end of the movable block 10. A toggle block 12 is fixedly connected to the top of the movable block 10.

[0025] Preferably, the two mounting bases 8 are symmetrically distributed, the two positioning grooves 4 are also symmetrically distributed, the dimensions of the mounting bases 8 and the positioning grooves 4 are compatible, and the dimensions of the limiting slots 5 and the limiting pins 11 at the ends away from the movable block 10 are compatible.

[0026] In practical use, the movable block 10 is moved by the toggle block 12 to retract the limit pin 11. Then, the connecting frame 6 and the filter element 7 are placed into the vertical static mixer housing 1 from the top, and the mounting base 8 is embedded in the positioning groove 4. At this time, by releasing the toggle block 12, the limit pin 11 can be ejected and inserted into the limit slot 5 under the action of the return spring 9, thereby installing the filter element 7 on the top of the vertical static mixer housing 1. The filter element 7 can be used to filter the natural gas fluid fed into the vertical static mixer to reduce wear, and at the same time improve the mixing uniformity and stability of the natural gas fluid.

[0027] Preferably, the filter element 7 can form an elastic engagement structure with the connecting flange 3 through the positioning groove 4, the limiting groove 5, the connecting frame 6, the mounting base 8, the return spring 9, the movable block 10, the limiting pin 11, and the toggle block 12.

[0028] In practical use, the movable block 10 is moved by the lever 12 to cause the limit pin 11 to retract. At this time, one end of the limit pin 11 will disengage from the limit slot 5 inside the positioning slot 4. Then, the connecting frame 6 is lifted upward so that the mounting seat 8 connected to its outer wall can disengage from the positioning slot 4, thereby making it easy to remove the filter element 7.

[0029] Preferably, the surface of the connecting flange 3 is provided with an annular groove 13, and the surface of the connecting flange 3 is provided with a plurality of mounting holes 15 distributed in an annular pattern. An annular sealing ring 14 is bonded inside the annular groove 13.

[0030] In practical use, through the setting of the annular groove 13 and the annular sealing ring 14, when the connecting flange 3 at the top of the vertical static mixer housing 1 is connected to the natural gas transmission pipeline, the annular sealing ring 14 will be subjected to force and squeezed, thereby further improving the sealing performance at the connection between the vertical static mixer housing 1 and the natural gas transmission pipeline.

[0031] Working principle: First, by moving the movable block 10 with the toggle 12, the limiting pin 11 retracts. Then, the connecting frame 6 and filter element 7 are placed into the vertical static mixer housing 1 from the top, and the mounting base 8 is embedded in the positioning groove 4. At this time, by releasing the toggle 12, the limiting pin 11 can be ejected under the action of the return spring 9 and inserted into the limiting groove 5, thereby installing the filter element 7 on the top of the vertical static mixer housing 1. Then, by moving the movable block 10 with the toggle 12, the limiting pin 11 retracts, and one end of the limiting pin 11 will disengage from the limiting groove 5 inside the positioning groove 4. At this time, the connecting frame 6 is lifted upwards, so that the mounting base 8 connected to its outer wall can disengage from the positioning groove 4. This allows for easy removal of the filter element 7. Finally, through the setting of the annular groove 13 and the annular sealing ring 14, when the connecting flange 3 at the top of the vertical static mixer housing 1 is connected to the natural gas transmission pipeline, the annular sealing ring 14 will be subjected to force and squeezed, thereby further improving the sealing performance at the connection between the vertical static mixer housing 1 and the natural gas transmission pipeline. When natural gas fluid enters the interior of the vertical static mixer housing 1 from the top, the filter element 7 can filter the natural gas fluid fed into the vertical static mixer to reduce wear, and at the same time improve the mixing uniformity and stability of the natural gas fluid. The filtered natural gas fluid will then undergo static mixing under the action of the mixing unit 2.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
