Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation technology, and in particular to a gas-liquid separation device. Background Technology

[0002] In modern industrial production and daily life, gas-liquid separation technology is a key link in the separation and purification of substances and has a wide range of important applications. With the rapid development of industries such as chemical, energy, environmental protection, and food, higher requirements are being placed on the performance, efficiency and adaptability of gas-liquid separation devices.

[0003] However, in existing technologies, the separation efficiency is significantly reduced when dealing with relatively small droplets. Inertial separation relies on the droplets colliding with the baffle or being separated by centrifugal force during high-speed motion. However, small droplets are lightweight and have low inertia, making it easy for them to bypass obstacles with the gas flow. They are difficult to collide effectively with the baffle or generate sufficient centrifugal force to settle in the swirling flow field. Utility Model Content

[0016] In a preferred embodiment, the liquid storage tank is fixedly connected to the outer wall of the separation tank.

[0017] The above technical solution is adopted: when in use, the liquid storage tank is fixedly connected to the outer wall of the separation tank, and the liquid storage tank is avoided from being placed directly on the ground, as it is easy to detach.

[0036] 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.

[0037] like Figure 1-6 As shown, this utility model provides a technical solution: a gas-liquid separation device, comprising:

[0038] The separation chamber 1 has an inner frame 3 fixedly connected inside it, an installation port is opened at the bottom of the outer wall of the separation chamber 1, and a flange is installed on the top of the separation chamber 1.

[0039] The separation assembly 2 includes a top filter screen 21 and an inner rotating frame 24 slidably connected within the separation chamber 1. A fixed rod 27 is rotatably connected within the inner rotating frame 24, and a backflow rod 210 is fixedly connected to the bottom of the fixed rod 27. A second inclined plate 25 is fixedly connected within the inner rotating frame 24, and a rotating block 28 is threadedly connected to the fixed rod 27. The rotating block 28 is slidably connected to the bottom of the top filter screen 21. A rotating frame 22 is slidably connected to the bottom of the separation chamber 1, and a first inclined plate 23 is fixedly connected to the rotating frame 22.

[0040] This invention utilizes a motor 7 to drive a rotating frame 22 to form a multi-stage swirling flow field, enhancing the centrifugal force and collision probability of tiny droplets. A reverse flow rod 210 drives a rotating block 28 to generate periodic vibrations, promoting droplet desorption and filter coalescence. The spiral guide grooves on the inner wall of the inner frame 3, in conjunction with the rotational motion, shorten the droplet settling path and accelerate collection. The design of the threaded groove and annular groove limiting structure on the fixing rod 27 ensures efficient separation while reducing airflow resistance, avoiding the high energy consumption and clogging problems of traditional coalescing separators. Through multi-stage swirling flow enhancement, vibration-assisted desorption, and spiral guide flow, it effectively solves the problem of low efficiency in separating fine droplets using traditional inertial separation and gravity settling.

[0041] Furthermore, such as Figures 2 to 5As shown, the fixed rod 27 is slidably connected to the bottom of the inner wall of the inner rotating frame 24. An air vent is provided at the bottom of the inner wall of the inner rotating frame 24. An annular groove is provided on the outer wall of the inner rotating frame 24. A limiting rod 26 is slidably connected to the annular groove on the inner rotating frame 24. The limiting rod 26 is fixedly connected to the inner wall of the separation chamber 1. A threaded groove is provided on the fixed rod 27. The rotating block 28 is threadedly connected to the fixed rod 27 through the threaded groove on the fixed rod 27. In use, the threaded groove on the fixed rod 27 not only facilitates the water flow out, but also forms a spiral guide path when the fixed rod 27 rotates, which extends the movement trajectory of water droplets in the inner rotating frame 24 and increases the probability of collision with the inner frame 3. At the same time, the protruding structure of the threaded groove can form turbulence on the airflow, further promoting the aggregation of tiny droplets.

[0042] like Figure 6 As shown, a transmission disk 72 is fixedly connected to the bottom of the rotating frame 22, and a motor 7 is fixedly connected to the bottom of the transmission disk 72. A base plate 11 is fixedly connected to the side of the motor 7 away from the rotating frame 22. The base plate 11 is fixedly connected to the bottom of the inner wall of the separation chamber 1. In use, by fixing the transmission disk 72 to the bottom of the rotating frame 22, the driving force of the motor 7 is evenly transmitted to the rotating frame 22, ensuring that the first inclined plate 23 rotates at a stable angular velocity, forming a swirling field with controllable intensity, which assists the gas delivery of external equipment. This design can also adapt to different gas and liquid loads by adjusting the speed of the motor 7, thereby improving the operational flexibility of the device.

[0043] like Figure 4 As shown, a liquid extraction pipe 5 is fixedly connected to the rotating frame 22. A liquid storage tank 51 is fixedly connected to the side of the liquid extraction pipe 5 away from the separation tank 1. An extension pipe 53 is fixedly connected to the liquid storage tank 51. A water pump 52 is fixedly connected to the end of the extension pipe 53 away from the liquid storage tank 51. In use, by fixing the liquid extraction pipe 5 to the rotating frame 22 and cooperating with the water pump 52 to form a negative pressure suction system, the accumulated liquid in the rotating frame 22 can be discharged in time to avoid secondary liquid entrainment. The fixed connection between the liquid storage tank 51 and the outer wall of the separation tank 1 saves space and makes it easy to observe the liquid level. At the same time, it reduces pipe bends and reduces flow resistance.

[0044] like Figures 2 to 4 As shown, the inner wall of the inner frame 3 is provided with a guide channel. The guide channel on the inner wall of the inner frame 3 is distributed in an Archimedean spiral, which can guide the droplets to flow along the shortest path to the rotating frame 22. At the same time, the inclination angle of the spiral guide channel matches the rotation direction of the inner rotating frame 24, and the centrifugal force is used to accelerate the collection of liquid.

[0045] like Figure 2 As shown, the liquid storage tank 51 is fixedly connected to the outer wall of the separation tank 1. The fixed connection between the liquid storage tank 51 and the outer wall of the separation tank 1 saves space, facilitates the observation of the liquid level, and reduces pipe bends, thereby reducing flow resistance.

[0046] like Figure 3 As shown, a sliding rod 4 is fixedly connected to the rotating block 28. One end of the sliding rod 4 away from the rotating block 28 is slidably connected to the inner frame 3. A rubber rod 29 is fixedly connected to the rotating block 28. A damper 6 is fixedly connected to the sliding rod 4. One end of the damper 6 away from the sliding rod 4 is fixedly connected to the inner frame 3. A vertical groove is provided in the inner frame 3. The sliding rod 4 is slidably connected in the vertical groove in the inner frame 3. The sliding of the sliding rod 4 in the vertical groove of the inner frame 3, in conjunction with the damper 6 structure, causes the rotating block 28 to generate damped oscillation during the reset process, thereby enhancing the cleaning effect on the top filter screen 21.

[0047] Working principle:

[0048] like Figure 1-6 As shown, during use, the gas supply pipe is connected through the flange on the top of the separation chamber 1, and the gas inlet pipe is connected through the opening on the top of the separation chamber 1.

[0049] The gas-liquid mixture is introduced through the air intake pipe, and the motor 7 is started, which drives the rotating frame 22 to rotate. This causes the first inclined plate 23 to fan the airflow and rotate, which hits the inner wall of the inner frame 3. Some of the liquid hits the inner wall of the inner frame 3 and accumulates, flowing down the spiral guide channel on the inner wall of the separation chamber 1.

[0050] The airflow passes through the inner rotating frame 24, and the second inclined plate 25 drives the inner rotating frame 24 to rotate, causing the liquid droplets to further accumulate in the inner rotating frame 24.

[0051] The reverse flow rod 210 will be driven to rotate by the airflow, which will cause the fixed rod 27 to rotate. At this time, the rotating block 28 will be driven to slide up and down on the fixed rod 27 and rise upward. The rubber rod 29 will be used to push and squeeze the top filter screen 21, so that the top filter screen 21 is stuck in the separation chamber 1.

[0052] By operating the air intake, the staff can intermittently supply air to the separation chamber 1, which can cause the sliding rod 4 separation component 2 to be pulled back to its original position. The downward movement of the rotating block 28 will cause the fixed rod 27 to rotate, causing the inner rotating frame 24 to vibrate and spray water. The rotating block 28 will quickly strike the inner rotating frame 24, causing the water to fall off and slide into the rotating frame 22.

[0053] Then, the water pump 52 is started, which draws air into the liquid storage tank 51. The liquid storage tank 51 uses the liquid extraction pipe 5 to extract the liquid from the rotating frame 22, while the gas flows through the gas transmission pipe pre-installed on the top of the separation chamber 1.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
