Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas-liquid mixing, specifically to a micro gas-liquid mixer. Background Technology
[0002] Gas-liquid mixers are widely used in many industries such as chemical, environmental protection, food, and pharmaceutical. In chemical reactors, the mixing of gaseous and liquid reactants can increase the reaction rate and efficiency, thereby improving production efficiency.
[0003] Current mixers are generally large in size, which not only increases the footprint of the equipment but may also cause inconvenience during use. In addition, large mixers are prone to material residue, which affects the final reaction results. Most existing mixers use contact-type turbulence structures, such as stirring blades. Driven by the gas flow rate, the mixing effect of this structure is limited and is more suitable for mixing liquid reactions, while it may not be effective for gas-liquid mixing. Utility Model Content
[0004] To overcome the above-mentioned shortcomings, this utility model provides a micro gas-liquid mixer.
[0005] The technical solution adopted by this utility model is as follows:
[0006] A miniature gas-liquid mixer includes a mixing tube. Connector 1 and connector 2 are fixedly connected to the top and bottom of the mixing tube, respectively. Connector 1 has an inlet at the top and connector 2 has an outlet at the bottom. Both the inlet and outlet are connected to the mixing tube. The bottom and upper parts of the inner wall of the mixing tube are constricted. Five dispersing and separating components are evenly distributed from top to bottom inside the mixing tube. The dispersing and separating components are fixedly connected to the inner wall of the mixing tube. A mixing and flow structure is provided between two adjacent dispersing and separating components. The mixing and flow structure is connected to the dispersing and separating components.
[0007] The dispersing and separating component includes a short pipe, the outer wall of which is fixedly connected to the inner wall of the mixing pipe. A sieve plate is fixedly connected to the middle of the inner wall of the short pipe. A dispersing protrusion is fixedly connected to the center of the top of the sieve plate. The dispersing protrusion is conical. Sieve holes are opened at the top of the sieve plate and are evenly distributed around the dispersing protrusion.
[0008] The mixing and flow structure includes a partition plate located between two short pipes, which is fixedly connected to the inner wall of the mixing pipe. An upper connecting plate is fixedly connected to the top of the partition plate and inserted into the bottom of the inner wall of the upper short pipe. A mixing groove, shaped like an inverted frustum, is opened in the center of the top of the upper connecting plate. A lower connecting plate, shaped like an inverted frustum, is fixedly connected to the bottom of the partition plate and inserted into the top of the inner wall of the lower short pipe. The lower short pipe is fitted with the lower connecting plate. A flow groove, shaped like a frustum, is opened in the center of the bottom of the lower connecting plate. There is a gap between the flow groove and the dispersing protrusion. A connecting hole is opened in the middle of the partition plate, which connects the bottom of the mixing groove and the top of the flow groove.
[0009] The beneficial effects of this utility model are:
[0010] This invention features a small size, excellent mixing effect, stable mixing results, and low pressure resistance. Through its internal structure, it enables thorough mixing of multiple gases or liquids, or multiple gases and liquids simultaneously. The compact design occupies little space, making it easy to install and use in limited spaces. Through multiple processes of dispersing, separating, and agglomerating, the fluid is thoroughly mixed within the mixing tube, resulting in high mixing uniformity.
[0011] Because the mixing process uses a forced mixing method, and each mixing process involves a dispersing and separating component and a coagulation and mixing flow structure, the mixing results are stable and reliable. Attached Figure Description

[0015] like Figure 1-2 As shown: A miniature gas-liquid mixer includes a mixing tube 1. The top and bottom ends of the mixing tube 1 are fixedly connected to a first connector 2 and a second connector 4, respectively. The first connector 2 has an inlet 3 at its top and the second connector 4 has an outlet 5 at its bottom. Both the inlet 3 and the outlet 5 are connected to the mixing tube 1. The bottom of the inner wall of the mixing tube 1 is constricted, and the upper part of the inner wall of the mixing tube 1 is also constricted. Five dispersing and separating components 6 are evenly distributed from top to bottom inside the mixing tube 1. The dispersing and separating components 6 are fixedly connected to the inner wall of the mixing tube 1. A mixing and flow structure 7 is provided between two adjacent dispersing and separating components 6, and the mixing and flow structure 7 is connected to the dispersing and separating components 6.
[0016] The dispersing and separating component 6 includes a short pipe 61, the outer wall of which is fixedly connected to the inner wall of the mixing pipe 1. A sieve plate 62 is fixedly connected to the middle of the inner wall of the short pipe 61. A dispersing protrusion 63 is fixedly connected to the center of the top of the sieve plate 62. The dispersing protrusion 63 is conical. A sieve hole 64 is opened on the top of the sieve plate 62. The sieve hole 64 is evenly distributed around the dispersing protrusion 63.
[0017] The mixing and flow structure includes a partition 71 located between two short pipes 61. The partition 71 is fixedly connected to the inner wall of the mixing pipe 1. An upper connecting plate 72 is fixedly connected to the top of the partition 71 and inserted into the bottom of the inner wall of the upper short pipe 61. A mixing groove 73 is formed in the center of the top of the upper connecting plate 72. The mixing groove 73 is in the shape of an inverted frustum. A lower connecting plate 74 is fixedly connected to the bottom of the partition 71 and inserted into the top of the inner wall of the lower short pipe 61. The lower short pipe 61 is fitted with the lower connecting plate 74. A flow groove 75 is formed in the center of the bottom of the lower connecting plate 74. The flow groove 75 is in the shape of a frustum. There is a gap between the flow groove 75 and the dispersing protrusion 63. A connecting hole 76 is formed in the middle of the partition 71, which connects the bottom of the mixing groove 73 and the top of the flow groove 75.
[0018] Multiple gases or multiple liquids, or both gases and liquids, enter the mixing tube 1 through the inlet 3 at the top of the connector 2.
[0019] The upper part of the inner wall of the mixing tube 1 is constricted, which helps the fluid to form a certain flow velocity and pressure when entering the mixing tube 1, providing power for the subsequent mixing process.
[0020] After the fluid enters the mixing tube 1, it first encounters the dispersing and separating component 6. The fluid passes through the sieve plate 62 in the short tube 61. The sieve holes 64 on the sieve plate 62 disperse the fluid into smaller droplets or bubbles, increasing the contact area between the fluids.
[0021] The dispersing protrusions 63 on the top of the sieve plate 62 further agitate and disperse the fluid, making the fluid more evenly distributed in the mixing tube 1.
[0022] After being dispersed and separated, the fluid enters the mixing flow structure 7. The fluid first passes through the mixing groove 73 at the top of the upper connecting plate 72. The shape of the mixing groove 73 helps the fluid to form a vortex here, further promoting the mixing between fluids.
[0023] The fluid then enters the flow channel 75 below through the connecting hole 76 in the middle of the partition 71. The gap between the flow channel 75 and the dispersing protrusion 63 allows the fluid to continue mixing during the flow while maintaining a certain flow rate.
[0024] The above-mentioned dispersing and mixing process is repeated five times in the mixing tube 1, each time passing through a different dispersing component 6 and mixing structure 7 to ensure that the fluid is fully mixed.
[0025] Finally, the uniformly mixed fluid is discharged from the mixing tube 1 through the outlet 5 at the bottom of connector 2 4.
