Description

Technical Field

[0001] This utility model relates to the technical field of liquid-gas mixing pipelines, and more particularly to a liquid-gas mixing pipeline. Background Technology

[0002] With the development of technology, existing mixers are widely used in water treatment, chemical industry, and environmental protection. However, significant defects still exist in their design and operation, such as uneven water flow distribution and low liquid-gas mixing efficiency. Traditional ring network mixers suffer from large differences in local resistance due to their multiple bends and short pipe structures. Head loss in the edge areas causes deviations in the outlet flow rate, reducing reactor efficiency. Parallel flow channels lead to liquid stagnation, reducing reactant transport efficiency; and the excessive number of bends in the ring network increases local resistance.

[0003] In related technologies, existing liquid-gas mixing pipelines include a mixing pipeline body with a flow cavity for supplying liquid and gas flow. However, the liquid and gas are only mixed once in the flow cavity, resulting in poor mixing effect of liquid and gas in existing liquid-gas mixing pipelines. Utility Model Content

A docking flange is connected to the main body of the mixing pipeline and is located on one side of the main body of the mixing pipeline. The docking flange is used to dock with an external pipe body. The docking flange has a first mixing cavity, which is connected to the flow cavity. The first mixing cavity receives gas input from the external pipe. The liquid and gas are further mixed in the flow cavity to output a liquid-gas mixture. The gas-liquid mixture flows toward the flow cavity; the porous dispersion section is connected to the main body of the mixing pipe and is located on one side of the docking flange; the porous dispersion section has a second mixing cavity and multiple first dispersion holes; the second mixing cavity is connected to the flow cavity, and the multiple first dispersion holes are arranged in a ring along the porous dispersion section and connected to the second mixing cavity in different directions. The multiple first dispersion holes are used to divide the liquid-gas mixture flowing out of the second mixing cavity and output the liquid-gas mixture in different directions, so that the liquid-gas mixture in the flow cavity can be mixed multiple times through the multiple first dispersion holes, avoiding the liquid and gas being mixed only once in the flow cavity, and improving the mixing effect of the liquid-gas mixture in the liquid-gas mixing pipe.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0038] Please refer to the attached document. Figures 1-4 This application provides a liquid-gas mixing pipe 100 for multiple mixing of liquids and gases.

[0039] Please refer to the attached document. Figures 1-4In this embodiment, the liquid-gas mixing pipeline 100 includes a mixing pipeline body 10, a mounting flange 20, a docking flange 30, and a porous dispersion section 40. The mixing pipeline body 10 is provided with a flow cavity 10a, which is used for supplying liquid and gas flow and contains liquid and gas. The mounting flange 20 is connected to the mixing pipeline body 10 and is used to install external components. Liquid output from the external components flows through the mounting flange 20 to the flow cavity 10a. The docking flange 30 is connected to the mixing pipeline body 10 and is disposed on one side of the mixing pipeline body 10. The docking flange 30 is used to dock with an external pipe body and is provided with a first mixing cavity 30a, which communicates with the flow cavity 10a. The first mixing cavity 30a receives gas input from the external pipe, and the liquid and gas further mix within the flow cavity 10a. The mixture is mixed in one step to output a liquid-gas mixture, which flows toward the flow cavity 10a. A porous dispersion section 40 is connected to the mixing pipe body 10 and is disposed on one side of the docking flange 30. The porous dispersion section 40 is provided with a second mixing cavity 40a and a plurality of first dispersion holes 40b. The second mixing cavity 40a is connected to the flow cavity 10a. The plurality of first dispersion holes 40b are arranged in a ring along the porous dispersion section 40 and are connected to the second mixing cavity 40a in different directions. The plurality of first dispersion holes 40b are used to divide the liquid-gas mixture flowing out of the second mixing cavity 40a and output the liquid-gas mixture in different directions, so that the liquid-gas mixture in the flow cavity 10a can be mixed multiple times through the plurality of first dispersion holes 40b, avoiding the liquid and gas from being mixed only once in the flow cavity 10a, and improving the mixing effect of the liquid-gas mixture in the liquid-gas mixing pipe 100.

[0040] Please refer to the attached document. Figures 1-4 In this embodiment of the application, the mixing pipe body 10 is provided with a flow cavity 10a, which is used for the flow of liquid and gas and contains liquid and gas so as to facilitate the flow of liquid and gas inside the mixing pipe body 10.

[0041] The mounting flange 20 is located on the left side of the mixing pipe body 10 and is connected to the mixing pipe body 10. The mounting flange 20 is used to install external components so that the external components can be connected to the mixing pipe body 10 through the mounting flange 20, ensuring the connection effect between the external components and the mixing pipe body 10. The liquid output from the external components flows through the mounting flange 20 to the flow cavity 10a so that the liquid is inside the mixing pipe body 10.

[0042] The connecting flange 30 is connected to the mixing pipeline body 10 and is located on the upper side of the mixing pipeline body 10. The connecting flange 30 is used to connect to the external pipe body so that the external components can be connected to the mixing pipeline body 10 through the connecting flange 30, ensuring the connection effect between the external components and the mixing pipeline body 10. The gas output by the external components flows to the flow cavity 10a through the connecting flange 30 so that the gas is inside the mixing pipeline body 10.

[0043] The docking flange 30 is provided with a first mixing chamber 30a, which is connected to the flow chamber 10a. The first mixing chamber 30a receives gas input from an external pipeline. Liquid and gas are further mixed in the flow chamber 10a to output a liquid-gas mixture, which flows toward the flow chamber 10a to achieve the first mixing of liquid and gas.

[0044] The porous dispersion section 40 is connected to the mixing pipe body 10 and is disposed on one side of the docking flange 30. The porous dispersion section 40 is provided with a second mixing inner cavity 40a and a plurality of first dispersion holes 40b. The second mixing inner cavity 40a is connected to the flow inner cavity 10a. The plurality of first dispersion holes 40b are arranged in a ring along the porous dispersion section 40 and are connected to the second mixing inner cavity 40a in different directions. The plurality of first dispersion holes 40b are used to divide the liquid-gas mixture flowing out of the second mixing inner cavity 40a and output the liquid-gas mixture in different directions, so that the liquid-gas mixture in the flow inner cavity 10a can be mixed multiple times through the plurality of first dispersion holes 40b, avoiding the liquid and gas from being mixed only once in the flow inner cavity 10a, thereby improving the mixing effect of the liquid-gas mixture in the liquid-gas mixing pipe 100.

[0045] Please refer to the attached document. Figures 1-3 In this embodiment, the first mixing chamber 30a, the flow chamber 10a, the second mixing chamber 40a, and a plurality of first dispersion holes 40b are sequentially connected. Gas is input into the first mixing chamber 30a, and the gas mixes with the liquid in the flow chamber 10a to form a liquid-gas mixture. The liquid-gas mixture passes through the flow chamber 10a, the second mixing chamber 40a, and the plurality of first dispersion holes 40b in sequence, and is sprayed outward from the plurality of first dispersion holes 40b. This allows the liquid-gas mixture in the flow chamber 10a to undergo multiple mixing through the plurality of first dispersion holes 40b, avoiding the liquid and gas from mixing only once in the flow chamber 10a, and improving the mixing effect of the liquid-gas mixture in the liquid-gas mixing pipe 100.

[0046] Please refer to the attached document. Figures 1-3In this embodiment, the liquid and gas undergo initial mixing in the flow chamber 10a, followed by flow-type mixing. The liquid and gas can then be further mixed in the second mixing chamber 40a, and output as multiple sub-liquid-gas mixtures through the division of multiple first dispersion holes 40b. The volume of each sub-liquid-gas mixture is smaller than the volume of the liquid-gas mixture. During this flow-type mixing, the liquid and gas encounter resistance, and the multiple first dispersion holes 40b disrupt the original flow-type mixing state, cutting the water bubbles and creating secondary mixing. Under pressure, the liquid and gas are ejected through the porous dispersion head, allowing for more thorough mixing.

[0047] Please refer to the attached document. Figures 1-3 In this embodiment, the first mixing chamber 30a and the flow chamber 10a are vertically distributed to facilitate the downward flow of gas from the first mixing chamber 30a to the flow chamber 10a. This allows the gas to mix with the liquid in the flow chamber 10a under downward impact, ensuring the mixing effect of the gas and liquid. The flow chamber 10a and the second mixing chamber 40a are arranged in parallel, and the multiple first dispersion holes 40b are multidirectionally distributed with the second mixing chamber 40a. This allows the liquid-gas mixture in the flow chamber 10a to flow horizontally through the second mixing chamber 40a to the multiple first dispersion holes 40b, thereby facilitating the output of the liquid-gas mixture in the second mixing chamber 40a in multiple directions through the multiple first dispersion holes 40b.

[0048] Please refer to the attached document. Figures 1-4 In this embodiment, the axes of the plurality of first dispersion holes 40b are arranged at an incline and converge at the central axis of the second mixing cavity 40a. Due to the contraction effect of the plurality of first dispersion holes 40b and the guidance of the incline angle, the kinetic energy of the liquid-gas mixture increases, further promoting the mixing process between the liquid-gas mixture.

[0049] Please refer to the attached document. Figures 1-3 In this embodiment, the mixing pipe body 10 is cylindrical, and the flow cavity 10a extends along a straight direction; this facilitates the flow of the liquid-gas mixture within the flow cavity 10a to the second mixing cavity 40a in a straight line. Alternatively, the mixing pipe body 10 is serpentine, with the flow cavity 10a extending along a serpentine direction, thus extending the flow path and mixing time of the liquid-gas mixture, allowing for more opportunities for collision and mixing between the liquid and gas within the mixing pipe body 10. During the flow process, the relative motion of the liquid and gas constantly changes, which is beneficial for their thorough mixing.

[0050] Please refer to the attached document. Figures 1-3In this embodiment, the end of the docking flange 30 is inserted into the flow cavity 10a. There is a height difference between the end of the docking flange 30 and the peripheral wall of the flow cavity 10a. Gas is input into the flow cavity 10a along the end of the docking flange 30. When the gas is input into the flow cavity 10a along the end of the docking flange 30, due to the height difference, the gas will interact more with the liquid in the flow cavity 10a after entering the flow cavity 10a. The interaction can promote the mixing of gas and liquid and improve the uniformity of gas-liquid mixing.

[0051] Please refer to the attached document. Figures 1-3 In this embodiment, the flow cavity 10a is cylindrical or V-shaped. When the flow cavity 10a is V-shaped, the inner diameter of the end of the connecting flange 30 is larger than that of the beginning of the connecting flange 30 to facilitate the mixing of gas and liquid. When the liquid enters the flow cavity 10a, the change in inner diameter creates more eddies and turbulence. These eddies and turbulence can promote the interaction between the liquid and gas, improving the uniformity of liquid-gas mixing.

[0052] Please refer to the attached document. Figures 1-4 In this embodiment, the porous dispersion section 40 is further provided with a second dispersion hole 40c. The second dispersion hole 40c and the first dispersion hole 40b are opened on different sidewalls in the porous dispersion section 40. The second dispersion hole 40c is connected to the second mixing cavity 40a along the length direction of the porous dispersion section 40, so that the liquid-gas mixture in the second mixing cavity 40a can flow in multiple directions through the first dispersion hole 40b and the second dispersion hole 40c, thus ensuring the flow efficiency of the liquid-gas mixture to the external environment.

[0053] In this embodiment, the aperture of the second dispersion hole 40c is equal to that of the first dispersion hole 40b; there are multiple second dispersion holes 40c, and the array of multiple second dispersion holes 40c is arranged on the front sidewall of the porous dispersion part 40; the array of multiple first dispersion holes 40b is arranged on the peripheral sidewall of the porous dispersion part 40, so that the liquid-gas mixture can flow evenly to the external environment from multiple directions, making the liquid-gas mixture more evenly distributed.
