Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separator technology, and in particular to a gas-liquid separator with sediment collection function. Background Technology

[0002] Gas-liquid separation technology, as a core component of industrial processes, is widely used in petrochemicals, natural gas extraction, pharmaceutical engineering, and environmental protection. Traditional gas-liquid separators primarily target the separation of liquid droplets within gases. However, with increasing process complexity, the presence of solid particles, colloidal precipitates, and corrosive substances in mixed fluids places higher demands on equipment performance. For example, in MVR evaporation systems, if crystalline salts and organic precipitates in the material are not effectively captured, they can directly lead to impeller wear in the steam compressor, shortening equipment lifespan. In natural gas extraction, if sand particles and iron sulfide precipitates carried by formation water are not separated, they can cause pipeline blockage and corrosion problems.

[0003] A gas-liquid separator with announcement number CN220276526U relates to the field of gas-liquid separation. The gas-liquid separator includes a tank body, and further includes: a feed pipe disposed on the tank body and connected to the tank body; a top plate fixedly connected to the inner wall of the tank body, with a first partition fixedly connected to the top plate; a second partition fixedly connected to the top inner wall of the tank body, forming a flow channel between the first and second partitions; a first filter hole disposed on the top plate; and an outlet pipe disposed on the top of the tank body. The first partition divides the top plate into a feed zone and a discharge zone, the second partition is located within the feed zone on the top plate, the first filter hole is disposed on the feed zone, and the outlet pipe is positioned above the discharge zone. In this invention, the first and second partitions increase the path of gas flow and circulation within the tank body, thereby increasing the gas circulation time within the tank body and improving the efficiency and effect of gas-liquid separation.

[0004] The existing technology described above uses a single baffle and filter holes for gas-liquid separation, which is a simple method. The baffle separates droplets by gravity settling, but small droplets have low inertia and slow settling speed, making them easy to be entrained by gas through the filter holes, resulting in low gas-liquid separation efficiency. Furthermore, when the flow rate suddenly increases, the gas turbulence intensifies, making droplets more likely to be entrained. When the flow rate decreases, the liquid stays on the baffle surface for too long, which may form a liquid film that blocks the filter holes. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a gas-liquid separator with sediment collection function to solve the problem of low gas-liquid separation efficiency of existing gas-liquid separators mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas-liquid separator with sediment collection function, comprising a gas-liquid separator body, a drain pipe, a control panel, and an air inlet pipe. An inspection door is movably connected to one side of the gas-liquid separator body, an air inlet pipe is connected to the top outer side of the gas-liquid separator body, a drain pipe is connected to the bottom outer side of the gas-liquid separator body, and a control panel is provided on the outer side of the gas-liquid separator body.

[0007] The bottom of the gas-liquid separator body is connected to a bearing seat, and an exhaust pipe is rotatably connected inside the bearing seat. A rotating mechanism is provided on the outside of the exhaust pipe, and conveying blades are uniformly fixedly sleeved on the outside of the exhaust pipe. A gas-liquid separation component is provided inside the gas-liquid separator body, and a sediment separation and collection component is connected to the bottom of the gas-liquid separator body.

[0008] Furthermore, the exhaust pipe has a coolant chamber inside, which is filled with coolant, and the coolant is automatically changed using an external water pipe.

[0009] Furthermore, the rotating mechanism includes a support plate, which is fixed to the outside of the gas-liquid separator body. A power motor is connected to the top of the support plate, and a rotating shaft is fixed to the output shaft end of the power motor. A main gear is fixed to the outside of the rotating shaft, and a driven gear meshes with one side of the main gear. The driven gear is rotatably connected to the top of the gas-liquid separator body.

[0010] Furthermore, a secondary gear meshes with one side of the driven gear, and the secondary gear is fixedly sleeved on the exhaust pipe.

[0011] Furthermore, the gas-liquid separation component includes liquid-blocking frames disposed on both sides inside the exhaust pipe, and exhaust holes are uniformly disposed on the top of each liquid-blocking frame. Exhaust grooves are uniformly disposed on each liquid-blocking frame. The liquid-blocking frame is open, and multiple liquid-blocking columns are uniformly connected to the opening.

[0012] Furthermore, the bottom end of the exhaust pipe is threadedly connected to a bottom cover, and the bottom cover is uniformly connected with intercepting columns, all of which are made of stainless steel.

[0013] Furthermore, the sediment separation and collection assembly includes a dust collection plate disposed at the bottom of the gas-liquid separator body, and the dust collection plate is uniformly provided with through holes, and a dust collection mechanism is disposed inside the through holes.

[0014] Furthermore, the dust collection mechanism includes two support blocks, both of which are located inside the through hole. Each support block has a guide post connected to its top, and a return spring is evenly wound around each guide post. A dust collection screen is connected between the guide posts.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the gas-liquid separator with sediment collection function can efficiently separate gas and liquid, and can separate and collect sediment in the separated liquid to prevent blockage of the pipeline during the discharge process;

[0016] By utilizing the rotation of the exhaust pipe and multiple conveying blades, the gas-liquid mixture moves radially outward. Due to its higher density, the liquid experiences stronger centrifugal force and is thrown towards the inner wall of the gas-liquid separator body, while the gas, due to its lower density, concentrates in the central area, forming a preliminary gas-liquid separation. Furthermore, during the rotation of the conveying blades, a spiral downward flow channel is formed, causing the liquid and gas to flow downward. The liquid's own weight accelerates its downward settling, achieving secondary separation and improving the gas-liquid separation efficiency.

[0017] Then the gas rises and flows into the exhaust pipe from the bottom, making initial contact with multiple intercepting columns and impacting the liquid-blocking frame. The residual liquid carried in the gas further impacts the inner wall of the liquid-blocking frame and the liquid-blocking columns under the action of inertia, causing the small droplets in the impact to gradually gather into large droplets and be further separated, making the separation more thorough.

[0018] After separation, the liquid falls and passes through the dust collection screen, achieving partial and complete separation of gas and liquid. During this process, impurities and sediments in the liquid are intercepted on the dust collection screen, thus achieving sediment collection.

[0019] As the liquid flows through the through hole, it pushes the dust collection screen downwards and compresses the return spring. When the liquid impact is complete, the guide post returns to its original position, pushing the dust collection screen upwards and generating instantaneous vibration. This prevents the dust collection screen from being blocked by sediment, allowing the separated liquid to flow normally and finally be discharged from the drain pipe. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Please see Figures 1-6 The present invention provides the following technical solution:

[0030] Example 1: To address the problem of low separation efficiency in existing gas-liquid separators, the following technical solution is disclosed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6A gas-liquid separator with sediment collection function includes a gas-liquid separator body 1, a drain pipe 2, a control panel 3, and an air inlet pipe 4. An inspection door 7 is movably connected to one side of the gas-liquid separator body 1. The air inlet pipe 4 is connected to the top outer side of the gas-liquid separator body 1, and the drain pipe 2 is connected to the bottom outer side of the gas-liquid separator body 1. The control panel 3 is located on the outer side of the gas-liquid separator body 1. A bearing seat 8 is connected to the bottom inside the gas-liquid separator body 1, and an exhaust pipe 6 is rotatably connected inside the bearing seat 8. A coolant chamber 601 is located inside the exhaust pipe 6 and is filled with coolant, allowing for automatic coolant replacement via an external water pipe. A rotating mechanism 5 is located on the outer side of the exhaust pipe 6. The rotating mechanism 5 includes a support plate 501, which is fixed to the outside of the gas-liquid separator body 1. A power motor 502 is connected to the top of the support plate 501. A rotating shaft 503 is fixed to the output shaft end of the power motor 502. A main gear 504 is fixed to the outside of the rotating shaft 503. A driven gear 505 meshes with one side of the main gear 504 and is rotatably connected to the top of the gas-liquid separator body 1. A secondary gear 506 meshes with one side of the driven gear 505 and is fixedly sleeved on the exhaust pipe 6. A bottom cover 10 is threaded to the bottom end of the exhaust pipe 6, and intercepting columns 1001 are evenly connected inside the bottom cover 10. All intercepting columns 1001 are made of stainless steel.

[0031] The exhaust pipe 6 is uniformly and fixedly fitted with conveying blades 9. The gas-liquid separator body 1 is equipped with a gas-liquid separation component. The gas-liquid separation component includes a liquid-blocking frame 13 set on both sides inside the exhaust pipe 6. The top of the liquid-blocking frame 13 is uniformly provided with exhaust holes 1301. The liquid-blocking frame 13 is uniformly provided with exhaust grooves 1302. The liquid-blocking frame 13 is open, and multiple liquid-blocking columns 1303 are uniformly connected to the opening.

[0032] In this embodiment, the gas-liquid mixture is introduced into the gas-liquid separator body 1 through the inlet pipe 4. Then, the power motor 502 drives the rotating shaft 503 and the main gear 504 to rotate. The main gear 504 meshes with the driven gear 505, and the driven gear 505 meshes with the secondary gear 506, causing the secondary gear 506 to rotate. This, in turn, drives the exhaust pipe 6 and the conveying blades 9 to rotate, causing the gas-liquid mixture to move radially outward. The liquid, due to its higher density, experiences a stronger centrifugal force and is thrown against the inner wall of the gas-liquid separator body 1, achieving initial gas-liquid separation. Then, the rotating conveying blades 9 form a spiral downward flow channel, allowing the liquid to... The gas flows downwards and is accelerated to settle downwards by the weight of the liquid, achieving secondary separation and improving the gas-liquid separation efficiency. Then, the gas flows into the exhaust pipe 6 from the opening at the bottom and is discharged. During this process, the gas first flows upwards through the bottom cover 10. The residual liquid carried in the gas further impacts the intercepting column 1001 under the action of inertia, achieving separation. Similarly, the separation of liquid can be accelerated by passing through two liquid baffles 13 and multiple liquid baffles 1303. In addition, an appropriate amount of coolant is injected into the cooling liquid chamber 601 to condense and separate the liquid in the gas flowing in the exhaust pipe 6, thereby optimizing the gas-liquid separation efficiency and effect.

[0033] Example 2: This example differs from Example 1. By utilizing the dust collection mechanism 12, the separated liquid can be filtered, and the precipitates in the liquid can be collected, preventing pipe blockage in later processes. Therefore, the following technical solution is disclosed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 4 The bottom of the gas-liquid separator body 1 is connected to a sediment separation and collection assembly. The sediment separation and collection assembly includes a dust collection plate 11 disposed at the bottom of the gas-liquid separator body 1, and the dust collection plate 11 is uniformly provided with through holes 1101, and a dust collection mechanism 12 is disposed inside the through holes 1101. The dust collection mechanism 12 includes two support blocks 1204, and both support blocks 1204 are disposed inside the through holes 1101. The top of each support block 1204 is connected to a guide post 1202, and a return spring 1203 is uniformly wound on each guide post 1202. A dust collection screen 1201 is connected between the guide posts 1202.

[0034] In this embodiment, the separated liquid falls downwards under its own weight and flows through the through hole 1101 onto the dust collection screen plate 1201. The dust collection screen plate 1201 filters the liquid, thereby separating and capturing impurities and precipitates in the separated liquid. Finally, the liquid is discharged from the drain pipe 2. When the separated liquid falls onto the dust collection screen plate 1201, its own weight causes the dust collection screen plate 1201 to move downwards, sliding along the dust collection screen plate 1201 and compressing the return spring 1203. The more liquid is collected, the greater the compressive force received by the guide column 1202. Therefore, under the elastic reset action of the return spring 1203, the dust collection screen plate 1201 is pushed upwards and shaken to disperse the precipitates and prevent the collected precipitates from clogging the dust collection screen plate 1201 too quickly.
