Description

Technical Field

[0001] This application relates to the field of gas dispersion technology, and in particular to a gas outlet device. Background Technology

[0002] With the continuous development of industrialization, gas dissolution and dispersion technologies have been widely applied in various industries, especially in water treatment, aquaculture, wastewater treatment, and the chemical industry. Efficient gas dissolution and uniform dispersion have become crucial technologies for improving production efficiency and optimizing process effects. In these applications, effective gas dissolution not only improves system performance but also effectively reduces energy consumption and enhances process efficiency.

[0003] Traditional methods introduce gas into the liquid through aeration pipes, which typically employ a single pipe or a simple porous structure. These designs have inherent drawbacks, particularly in gas distribution and dissolution efficiency. Uneven gas pressure distribution within the pipes of traditional devices leads to uneven gas output. This uneven gas distribution causes the following problems:

[0004] 1. Low gas dissolution efficiency: Due to uneven gas distribution, there is an excess of gas in some areas, forming large bubbles. These bubbles are difficult to be fully dissolved by the liquid, or even escape directly from the liquid surface, resulting in gas waste and failing to effectively improve gas dissolution efficiency.

[0005] 2. High energy consumption: In order to ensure the gas output of the remote orifice, the traditional system needs to increase the overall gas supply pressure, which leads to an excessive increase in gas flow rate, thus significantly increasing the system's energy consumption.

[0006] 3. Shortened equipment lifespan: Under the influence of uneven airflow, the high airflow velocity in local areas may accelerate the wear of pipes or small holes, leading to equipment failure and increased maintenance costs, thus shortening the equipment's lifespan.

[0007] Therefore, existing gas dispersion devices have certain shortcomings in terms of gas dissolution efficiency, energy consumption, and equipment maintenance. These problems need to be solved through optimized design to improve the uniformity of gas dispersion and dissolution efficiency, reduce energy consumption, and extend the service life of the equipment. Utility Model Content

[0008] To improve the uniformity of gas dispersion and dissolution efficiency, this application provides a gas outlet device.

[0009] The gas outlet device provided in this application adopts the following technical solution:

[0010] An air outlet device includes a main pipe, a branch pipe, a secondary pipe, and a branch line pipe. The secondary pipe is connected to the main pipe, and the branch line pipe is connected to the branch pipe through the secondary pipe. The branch line pipe has multiple holes, which are evenly distributed along the length of the branch line pipe, and adjacent holes are staggered.

[0011] By adopting the above technical solution, this gas outlet device optimizes gas emission and dispersion by using multiple evenly distributed and staggered holes, improving the uniformity of gas within the pipeline, avoiding concentrated gas flow, and ensuring stable gas diffusion and dissolution efficiency. This design allows for more uniform gas distribution in the liquid, increasing the gas-liquid contact area and reducing bubble formation, thereby accelerating gas dissolution and improving dissolution efficiency, particularly in applications requiring high gas dissolution rates. This device not only improves gas dispersion and dissolution efficiency but also optimizes system operation, exhibiting high energy efficiency and durability. It is suitable for various industrial processes requiring gas dissolution, improving overall process performance.

[0012] In one specific implementation, a distance is left between the end of the branch pipe and the end of the main pipe.

[0013] By adopting the above technical solution, a certain distance is left between the end of the branch pipe and the end of the main pipe, which will generate a certain static pressure at the end of the main pipe and the connection of the branch pipe. The formation of static pressure helps the gas to flow smoothly in the pipe, reduces the fluctuation and unevenness of the airflow, and enables the gas to flow evenly from the main pipe to the branch pipe, and ensures the uniformity of gas delivery in each branch pipe.

[0014] In one specific implementation, the plurality of holes have the same diameter.

[0015] By adopting the above technical solution and maintaining the same orifice diameter, it is possible to avoid excessively high or low local flow velocities, reduce instability caused by uneven airflow, ensure smooth gas flow in the system, avoid local gas stagnation or concentration, and thus improve the stability of the system.

[0016] In one specific implementation, the angle range of two adjacent holes being staggered is 30-60°.

[0017] By adopting the above technical solution, the staggered angle design of adjacent holes effectively breaks the pattern of gas emission in a single direction, allowing the gas to be distributed more evenly in the pipe and avoiding the problem of excessive airflow concentration or uneven local emission. The staggered angle design can reduce the interference of airflow between adjacent holes, reduce the mutual influence of airflow during the emission process, and improve the stability and uniformity of gas emission.

[0018] In one specific implementation, the plurality of holes are distributed in a wavy pattern.

[0019] By adopting the above technical solution, the wavy arrangement of the holes effectively breaks the uniformity of gas emission, allowing the gas to be distributed more evenly in the pipe, avoiding the phenomenon of excessive concentration of airflow in certain areas, increasing the diffusion range of the gas, and the gas is discharged along the wavy path, resulting in a more uniform distribution in the liquid, increasing the contact area between the gas and the liquid, thereby improving the gas dissolution efficiency.

[0020] In one specific implementation, the branch pipe is arranged perpendicularly to both the main pipe and the secondary pipe.

[0021] By adopting the above technical solution, and by using branch pipes to be set perpendicular to the main pipes and auxiliary pipes, gas can flow quickly and directly from the main pipes, branch pipes, and auxiliary pipes to the branch pipes, reducing energy loss caused by pipe bends or unnecessary flow resistance; and the vertically set pipe design can be rationally laid out in a limited space, avoiding excessive horizontal space occupation by the pipes.

[0022] In one specific implementation scheme, there are multiple branch pipes and multiple secondary pipes, and each branch pipe and each secondary pipe is configured in a one-to-one correspondence.

[0023] By adopting the above technical solution, and by setting up multiple branch pipes and multiple secondary pipes, the corresponding setting of each branch pipe and a specific secondary pipe can ensure that the fluid is evenly distributed to each target area, avoid the problem of flow overload or flow imbalance in a single pipe, and improve gas emission efficiency.

[0024] In one specific implementation, the branch pipes are configured as multiple, and the multiple branch pipes are evenly distributed along the length direction of the secondary pipe.

[0025] By adopting the above technical solution, the uniform distribution design makes the installation layout of branch pipelines more reasonable. Multiple branch pipelines work together, reducing the burden on a single discharge port and ensuring that gas or liquid can be discharged evenly from multiple locations. The amount of fluid received by each branch pipeline is roughly the same, avoiding uneven efficiency caused by excessive or insufficient flow, thereby improving the stability and discharge efficiency of the system.

[0026] In one specific implementation scheme, the two ends of the secondary pipe are closed, and the end of the branch pipe away from the secondary pipe is the closed end.

[0027] By adopting the above technical solution, the closed design at both ends of the secondary pipe can better control the flow direction and flow rate of the gas, ensuring that the gas will not leak or flow disorderly from both ends of the secondary pipe. Through this design, the gas can only flow along the branch pipe, thereby improving the gas guidance and flow stability. The closed end of the branch pipe away from the secondary pipe further restricts the gas flow path, and the gas can only be discharged through specific holes, ensuring the uniformity and effectiveness of gas dispersion. The closed port prevents gas leakage, maintains the airtightness of the system, and further improves the gas utilization rate of the system.

[0028] In one specific implementation scheme, the main pipeline is provided with an air inlet, and the air inlet is provided with a pneumatic valve.

[0029] By adopting the above technical solution, a pneumatic valve is installed at the air inlet of the main pipeline, allowing the gas to pass smoothly when entering the main pipeline, but preventing it from returning along the same path. This unidirectional flow control can avoid the phenomenon of gas backflow, thereby maintaining the stability and efficiency of the airflow inside the system.

[0030] In summary, the beneficial technical effects of this application are as follows: This application improves the dissolution efficiency and uniform distribution of gas in liquid by optimizing the pipeline system and orifice design; the device adopts a hierarchical pipeline structure, including main pipeline, branch pipeline, secondary pipeline and branch line pipeline, combined with static pressure control, the pipeline system ensures stable gas flow, avoids turbulence and leakage, and the gas is evenly discharged through diversion and regulation, thereby improving the diffusion effect in liquid;

[0031] Furthermore, by designing staggered and wavy orifices, the contact area between gas and liquid is increased, ensuring uniform gas diffusion in water. The angle and distribution of the orifices effectively prevent airflow concentration and uneven local flow velocity, reduce airflow fluctuations and bubble extrusion, and accelerate gas dissolution.

[0032] This device can be widely used in water treatment, aquaculture, and wastewater treatment, significantly improving gas dissolution efficiency and optimizing system stability and economic benefits. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0038] Reference Figures 1-3 This application discloses a gas discharging device, including but not limited to gas dissolution and gas dispersion, particularly in water treatment, aquaculture, wastewater treatment, and chemical industry. Through the optimized design of this device, the gas emission and dispersion effect can be improved, thereby increasing the gas dissolution efficiency and distribution uniformity in the liquid.

[0039] The gas outlet device includes a main pipe 1, a branch pipe 2, an auxiliary pipe 3, and a branch line pipe 4, with the following specific structure:

[0040] Main pipe 1: Main pipe 1 connects to the gas source and is responsible for introducing gas;

[0041] Branch pipe 2: Branch pipe 2 branches off from main pipe 1 and connects to branch pipe 4 through secondary pipe 3;

[0042] Sub-pipe 3: Sub-pipe 3 is used to provide a certain static pressure during gas flow, which helps to ensure the smooth flow of gas from branch pipe 2 to branch pipe 4;

[0043] Branch pipe 4: Branch pipe 4 branches off from the secondary pipe 3. Multiple holes 41 are provided on one side of the bottom surface of branch pipe 4. The holes are evenly distributed along the length of branch pipe 4, and adjacent holes 41 are staggered to ensure that the gas can be discharged evenly. In this embodiment, the interval between two adjacent holes 41 includes, but is not limited to, 1 cm.

[0044] During operation, the system introduces gas from the gas source through the main pipe 1. The gas is then diverted from the main pipe 1 to the branch pipe 2, which is connected to the secondary pipe 3. The gas flows from the branch pipe 2 into the secondary pipe 3, and after passing through the secondary pipe 3, it enters the branch pipe 4 and is then discharged into the water through staggered holes 41. During the discharge process, the gas is uniform and dispersed, reducing the phenomenon of water bubbles rising and thus accelerating the dissolution efficiency of the gas in the water.

[0045] This gas outlet device significantly improves the uniformity and dispersion of gas by optimizing the orifice distribution and staggering the arrangement, reducing the phenomenon of water bubbles rising up. The gas dissolves more evenly in the liquid, increasing the contact area between the gas and the liquid, thereby accelerating the gas dissolution efficiency. At the same time, the uniform airflow reduces the concentrated flow of gas, avoids excessively large local bubbles or rising up, ensures the smooth diffusion of gas, and improves the stability and energy efficiency of the system.

[0046] In this embodiment, the air outlet device is placed vertically in the water. The branch pipe 2 is perpendicular to the main pipe 1 and the secondary pipe 3. In this embodiment, the main pipe 1, branch pipe 2, secondary pipe 3 and branch pipe 4 are welded together. In other embodiments, they can also be connected by a detachable connection. The main pipe 1 is horizontally arranged, the branch pipe 2 is vertically arranged, and there are 3 branch pipes. The branch pipes 2 are evenly distributed along the length of the main pipe 1. There are 3 secondary pipes, which are arranged one-to-one with the branch pipes 2. The secondary pipes 3 are horizontally arranged, and the horizontal direction of the secondary pipes 3 is perpendicular to the horizontal direction of the main pipe 1.

[0047] Each secondary pipe 3 has multiple branch pipes 4, which are evenly distributed along the length of the secondary pipe 3. The number of branch pipes 4 on each secondary pipe 3 can be the same or different, and can be adjusted according to actual needs. Multiple branch pipes 4 can be set on one or both sides of the secondary pipe 3. In this embodiment, eight branch pipes 4 are symmetrically arranged on both sides of the branch pipe 4 on the secondary pipe 3 located in the middle, and eight branch pipes 4 are only arranged on the inner side of the secondary pipe 3 located on both sides. The length of the branch pipes 4 on different secondary pipes 3 can be the same or different, including but not limited to 12cm.

[0048] In this embodiment, a certain distance is left between the branch pipes 2 on both sides and the end of the main pipe 1. The distance can be, but is not limited to, 1-5cm. This distance design allows a certain static pressure to be generated at the connection between the end of the main pipe 1 and the branch pipe 2. This static pressure can reduce airflow fluctuations and unevenness, and promote the uniformity of gas flow. The static pressure allows the gas to flow into the branch pipe 2 evenly. Furthermore, by setting multiple branch pipes 4, each branch pipe 4 can evenly distribute the gas under the same flow conditions, ensuring that the discharge effect of each branch pipe 4 is consistent and avoiding the reduction in system efficiency caused by uneven airflow.

[0049] In this embodiment, each branch pipe 4 is provided with multiple holes 41. The number of branch pipes 4 on different secondary pipes 3 can be the same or different. The hole diameter of all branch pipes 41 is the same. In this embodiment, the hole diameter of the hole 41 includes, but is not limited to, 6mm. By keeping the hole diameter the same, it is possible to ensure that the airflow rate is evenly distributed, avoid local flow rates that are too high or too low, reduce the instability caused by uneven airflow, and thus improve the stability of the system.

[0050] In this embodiment, two adjacent holes 41 are staggered by a certain angle A, which ranges from 30 to 60 degrees. The staggered design effectively avoids the phenomenon of excessive airflow concentration and reduces mutual interference between airflows between holes, thereby improving the stability and uniformity of gas flow. The staggered angle design of 30-60 degrees ensures that multiple holes 41 are located on one side of the bottom surface of the branch pipe 4, thus ensuring that the holes 41 can effectively discharge gas into the water. At the same time, this angle design can also reduce the interference of airflow between adjacent holes, reduce the mutual influence of airflows during the discharge process, and improve the stability and uniformity of gas discharge.

[0051] In this embodiment, the holes 41 on the same branch pipe 4 are arranged in a wavy pattern to further optimize the gas emission and dispersion effect. The wavy arrangement can enhance the contact area between the gas and the liquid, improve the gas dissolution efficiency, and increase the distribution range of the gas in the liquid, so that the gas can diffuse more evenly, thereby accelerating the gas dissolution.

[0052] In this embodiment, the two ends of the secondary pipe 3 are closed; this allows for better control of the gas flow direction and flow rate, ensuring that the gas does not leak or flow disorderly from the two ends of the secondary pipe 3. Through this design, the gas can flow smoothly into the branch pipe 4, avoiding the impact of airflow fluctuations or unevenness on the stability of the system.

[0053] In this embodiment, the end of the branch pipe 4 away from the secondary pipe 3 is a closed end 42; thereby further restricting the path of gas flow, the gas can only be discharged through a specific hole 41, ensuring the uniformity and effectiveness of gas dispersion.

[0054] In this embodiment, the main pipeline 1 is provided with an air inlet 11, with an air inlet pressure of 3.5-7 kg. The air inlet 11 is provided with a pneumatic valve (not shown in the figure). The pneumatic valve at the air inlet 11 of the main pipeline 1 allows the gas to pass smoothly when entering the main pipeline, but it cannot return along the same path. This unidirectional flow control can avoid the phenomenon of gas backflow, thereby maintaining the stability and efficiency of the airflow inside the system, and effectively avoiding potential failures and energy waste.

[0055] The implementation principle of this application embodiment is as follows: During operation, the gas outlet device is placed vertically in the water. Gas is introduced into the system through the main pipe 1, and the gas pressure is adjusted by the pressure regulating valve to ensure stable airflow. The gas is diverted from the main pipe 1 to three branch pipes 2, and then enters the corresponding secondary pipes 3 through the three branch pipes 2. After passing through the secondary pipes 3, the gas enters multiple branch pipes 4 on each secondary pipe 3. The gas is discharged into the water through multiple staggered holes 41 evenly arranged on the bottom surface of the branch pipes 4. After the gas is evenly discharged by this device, the gas velocity at each hole 41 is relatively small, which can reduce the emergence of water bubbles, ensure that the gas is evenly discharged into the water and effectively dispersed, thereby improving the gas dissolution efficiency.

[0056] This application improves the dissolution efficiency and uniformity of gas in liquid through a rationally designed pipeline system and orifice distribution. The device adopts a hierarchical design of main pipeline 1, branch pipeline 2, secondary pipeline 3 and branch pipeline 4. Through multiple staggered orifices 41 and wavy arrangement of orifices, the contact area between gas and liquid is effectively increased, ensuring uniform gas distribution in water. The staggered angle and distribution of orifices effectively avoid the phenomenon of airflow concentration and local flow velocity unevenness, reduce airflow fluctuations and bubble agitation, thereby accelerating the gas dissolution rate.

[0057] The structural design of the main pipeline 1, branch pipeline 2, secondary pipeline 3, and branch pipeline 4, combined with static pressure control, ensures the stability of gas flow and avoids turbulence or leakage during gas flow. Gas is gradually introduced into the water through the pipeline system. After multiple diversions and adjustments, the gas discharge of each branch pipeline 4 is uniform, thereby improving the diffusion effect of gas in the liquid.

[0058] The design of this device can not only significantly improve the efficiency of gas dissolution, but also achieve a more uniform gas dispersion effect in multiple application scenarios such as water treatment, aquaculture, and wastewater treatment, thereby improving the operational stability and economic benefits of the entire system.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
