Description

Technical Field

[0001] This utility model relates to the technical field of gas-liquid separation equipment, specifically a gas-liquid separator for a collection tank. Background Technology

[0002] Solution collection tanks can greatly improve the continuity, stability and safety of the production process. They are widely used in many fields such as chemical production, environmental protection, food processing, and nuclear power plants. In order to prevent gas from accumulating and overpressure in the tank, avoid fluid dynamic instability, increase the effective volume of the tank, and ensure the safe and long-term operation of the equipment, it is necessary to separate the gas and liquid in the solution entering the collection tank.

[0003] Traditional gas-liquid separators allow the gas-liquid mixture to enter directly, impacting the separator's internal structure. This impact can lead to seal failure and leakage due to excessive force, affecting separation efficiency and production safety. Furthermore, concentrated liquid flow reduces the effectiveness of initial gas-liquid separation, increasing maintenance frequency. Simultaneously, impurities in the gas and liquid easily adhere to the filter surface during separation, causing clogging over time and requiring frequent shutdowns for cleaning. This increases maintenance costs, disrupts continuous operation, and hinders normal production, making them unsuitable for use in strictly controlled nuclear power plant isolation zones. Additionally, some separators experience unstable liquid flow efficiency under conditions of significant gas pressure fluctuations, further limiting separation effectiveness. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a gas-liquid separator for a collection tank. The gas-liquid separator guides the gas-liquid mixture entering the gas-liquid separator to the surrounding area through a guiding mechanism to avoid the liquid directly impacting the interior of the separator and reduce the occurrence of leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas-liquid separator for a collection tank, comprising a guiding mechanism, a diversion mechanism, and a backflushing mechanism installed within a protective mechanism. The diversion mechanism is positioned above the guiding mechanism and includes a diversion plate and drain holes. The diversion plate is detachably installed above the guiding mechanism, and multiple drain holes are respectively opened around the top of the diversion plate. The backflushing mechanism is slidably installed above the diversion mechanism and includes a piston and an exhaust groove. The piston is slidably connected to the center of the top of the diversion plate, and multiple exhaust grooves are respectively opened on the outer wall of the piston.

[0006] Furthermore, the protective mechanism includes a protective shell, a limiting ring, and a sealing gasket. The limiting ring is fixedly installed on the lower part of the inner sidewall of the protective shell, and the sealing gasket is fixedly installed on the top of the limiting ring.

[0007] Furthermore, the top of the protective shell is provided with a liquid inlet mechanism, which includes a top cover, a drainage tube, a mounting plate, and a filter screen. The top cover is bolted to the top of the protective shell, the drainage tube is bolted to the center of the top of the top cover, the mounting plate is disposed between the top cover and the protective shell, and the filter screen is fixedly installed on the inner side wall of the mounting plate.

[0008] Furthermore, the bottom of the protective shell is provided with an exhaust mechanism, which includes a lower cover and an exhaust pipe. The lower cover is bolted to the bottom of the protective shell, and the exhaust pipe passes through and is connected to the bottom of the lower cover.

[0009] Furthermore, the guiding mechanism includes a limiting plate, a guiding tube, a retaining ring, an exhaust port, a partition, and a pressure cap. The limiting plate is detachably connected to the inner wall of the protective shell and is located at the top of the limiting ring. The guiding tube is fixedly installed at the top of the limiting plate. The retaining ring is fixedly installed above the inner wall of the guiding tube. Multiple exhaust ports are respectively opened above the outer surface of the guiding tube. The partition is detachably installed above the inner wall of the guiding tube and is located above the retaining ring. The pressure cap is threadedly connected to the upper part of the inner wall of the guiding tube.

[0010] Furthermore, the diversion mechanism also includes support rods and guide holes. Multiple support rods are fixedly installed on the top of the diversion plate, and the bottom ends of the multiple support rods are inserted into the top of the limiting plate. One end of the support rod that extends out of the limiting plate is threaded with a fixing bolt. The guide hole is opened at the center of the top of the diversion plate, and the piston is slidably connected to the inner wall of the guide hole.

[0012] Furthermore, the bottom of the protective shell is provided with a drain pipe communicating with its inner cavity, and one end of the drain pipe that enters the protective shell is located above the limiting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The gas-liquid separator for the collection tank of this utility model is equipped with a diversion mechanism. The diversion mechanism, through the cooperation of the guide plate and the drain hole, can guide the gas-containing solution to the surroundings when it flows downwards, thereby avoiding the solution directly impacting the guiding mechanism, reducing the occurrence of leakage, reducing the number of maintenance times of the separator, and is suitable for nuclear power plant isolation areas with strict access control. When guiding the solution to the surroundings, it can more effectively achieve preliminary separation between liquid and gas, and when there is a large change in gas pressure above the guide plate, it can assist the solution to quickly pass through the drain hole.

[0015] 2. The gas-liquid separator for the collection tank of this utility model is equipped with a backflush mechanism. The backflush mechanism is configured with the cooperation of a piston and an exhaust groove. After the gas-liquid separation is completed, the gas is guided and transported upward, thereby achieving an upward reverse flow of the gas and blowing the gas upward. Therefore, the gas can be blown from bottom to top, which can blow away the impurities filtered on the filter screen, avoiding the situation where impurities are adsorbed for a long time and cause filter screen blockage. Furthermore, the reverse blowing of the gas can cause the impurities to be initially separated from the filter screen, thereby extending the filter screen cleaning interval, reducing the filter screen cleaning frequency, and meeting the usage requirements of nuclear power plant isolation areas.

[0016] 3. In summary, this utility model, by setting up a diversion mechanism and a backflushing mechanism, has a simple structure and reasonable design. It can not only reduce the risk of leakage in the solution collection tank, but also extend the interval between cleaning the filter screen of the gas-liquid separator, reduce the number of maintenance times, and lower the operating costs. It is not only suitable for the needs of general industrial production, but also meets the requirements for use in nuclear power plant isolation areas. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] This invention provides a separator for use in scenarios where gas-containing solutions are collected in collection tanks, particularly suitable for nuclear power plant isolation areas with strict access control. This embodiment improves the separator's structure to provide advantages in liquid diversion and gas backflushing. Specifically, taking the gas-liquid separation of gas-containing liquids as an example, as a preferred embodiment, the separator is a gas-liquid separator for collection tanks, capable of rapidly separating the gas from the gas-containing liquid.

[0027] Example: See Figures 1 to 4The gas-liquid separator for the collection tank provided in this embodiment includes a guiding mechanism 4, a diversion mechanism 5, and a backflushing mechanism 6 installed within a protective mechanism 1. The diversion mechanism 5 is positioned above the guiding mechanism 4 and includes a diversion plate 501 and drain holes 502. The diversion plate 501 is detachably installed above the guiding mechanism 4. Multiple drain holes 502 are respectively opened around the top of the diversion plate 501. Specifically, the middle part of the diversion plate 501 gradually bulges upward to form an upwardly protruding spherical surface, and its outer edge is a plane that contacts the spherical surface. The drain holes 502 are opened at the four peripheral edges of the diversion plate 501, thereby guiding the gas-liquid mixture to the surrounding areas, avoiding direct impact of liquid on the guiding mechanism, and thus reducing leakage. In other embodiments, the middle cross-section of the diversion plate 502 is an inverted V-shape. In this embodiment, the backflush mechanism 6 is slidably mounted above the diversion mechanism 5. The backflush mechanism 6 includes a piston 601 and an exhaust groove 605. The piston 601 is slidably connected to the center of the top of the diversion plate 501. A plurality of exhaust grooves 605 are respectively opened on the outer wall of the piston 601 and arranged along the length of the piston 601.

[0028] In this embodiment, a diversion plate 501 is detachably installed above the guiding mechanism 4. The diversion plate 501 guides the liquid to its surroundings, preventing the liquid from directly impacting the top of the guiding pipe 402, reducing mechanical impact and wear on the seals of the guiding mechanism 4. Simultaneously, the dispersed flow increases the gas-liquid contact area, improving the initial separation effect. Drain holes 502 are located around the top of the diversion plate 501, serving as liquid flow channels. During pressure fluctuations, they assist in the rapid discharge of liquid, preventing liquid accumulation on the surface of the diversion plate 501. Furthermore, the dispersed drainage further promotes gas-liquid separation. When the water hole 502 falls, the entrained gas is more easily released. The piston 601 is slidably connected to the inner wall of the guide hole 504. By sliding up and down, the state of the gas channel is changed. When the gas and liquid are separated, the piston 601 moves downward without affecting the normal separation. When backflushing, the piston 601 moves upward and guides the gas to flow upward through the exhaust groove 605 to achieve reverse blowing. The exhaust groove 605 is opened on the outer wall of the piston 601 as an upward channel for the gas during backflushing. The separated gas flows upward through the exhaust groove 605 to blow away the impurities adsorbed on the surface of the filter screen 204, avoid the filter screen 204 from being blocked, and maintain smooth liquid inlet.

[0029] In this embodiment, see Figure 2 , Figure 4 and Figure 5The protective mechanism 1 includes a protective shell 101, a limiting ring 102, and a sealing gasket 103. The limiting ring 102 is fixedly installed on the lower part of the inner wall of the protective shell 101, and the sealing gasket 103 is fixedly installed on the top of the limiting ring 102. The protective shell 101 serves as the external load-bearing structure of the gas-liquid separator, providing installation space and a protective barrier for all internal mechanisms, avoiding interference from the external environment on the separation process, while ensuring the overall structural strength of the equipment, adapting to pressure fluctuations and mechanical vibrations in industrial settings, forming a closed separation chamber, ensuring that the gas-liquid mixture is separated within a controllable space, and improving the operational safety of the equipment. The limiting ring 102 is fixedly installed on the lower inner wall of the protective shell 101 to support and position the limiting plate 401 of the guide mechanism 4, restricting its displacement in the vertical direction, ensuring the stability of the guide mechanism 4 during separation, avoiding structural displacement caused by liquid impact or air pressure changes, and indirectly reducing the risk of leakage. The sealing gasket 103 is fixed to the top of the limiting ring 102 and fits tightly against the bottom of the limiting plate 401, enhancing the sealing between the limiting ring 102 and the limiting plate 401, preventing liquid from leaking from the gap between them, and improving their overall sealing performance.

[0030] In this embodiment, see Figure 1 and Figure 2 The protective housing 101 has a liquid inlet mechanism 2 on its top. The liquid inlet mechanism 2 includes a top cover 201, a drainage pipe 202, a mounting plate 203, and a filter screen 204. The top cover 201 is bolted to the top of the protective housing 101. The drainage pipe 202 is bolted to the center of the top of the top cover 201. The mounting plate 203 is positioned between the top cover 201 and the protective housing 101. The filter screen 204 is fixedly installed on the inner wall of the mounting plate 203. The top cover 201 is bolted to the top of the protective housing 101 and uses a sealing gasket to seal the top of the protective housing 101. This also provides a mounting base for the drainage pipe 202, facilitating disassembly and maintenance. The top can be quickly opened to inspect the internal filter screen 204, the flow distribution mechanism 5, etc. The drainage pipe 202, installed at the center of the top of the top cover 201, guides the gas-liquid mixture into the separator. Directional flow ensures the gas-liquid mixture enters along a stable path, avoiding turbulence at the inlet from affecting separation efficiency. The mounting plate 203 is located between the upper cover 201 and the protective shell 101, serving as the mounting carrier for the filter screen 204. This allows for the detachable connection of the filter screen 204, facilitating regular replacement or cleaning of the filter screen 204 and maintaining the filtration effect. The filter screen 204 is fixed to the inner wall of the mounting plate 203, performing preliminary filtration on the gas-liquid mixture entering the separator, intercepting solid impurities in the mixture, preventing impurities from entering subsequent mechanisms and causing blockage or wear, and extending the service life of the equipment.

[0031] In this embodiment, an exhaust mechanism 3 is provided at the bottom of the protective shell 101. The exhaust mechanism 3 includes a lower cover 301 and an exhaust pipe 302. The lower cover 301 is installed below the protective shell 101 by bolts and a sealing gasket. The exhaust pipe 302 passes through and is connected to the lower cover 301. The lower cover 301 is installed below the protective shell 101 by bolts, sealing the bottom of the protective shell 101 and providing an installation interface for the exhaust pipe 302. This facilitates opening the bottom to clean components such as the guide mechanism 4 and the exhaust port 404, meeting the maintenance needs after long-term use. The exhaust pipe 302 passes through and is connected to the lower cover 301 as a discharge channel for the separated gas, directionally exporting the gas separated by the guide mechanism 4 to ensure that the gas quickly leaves the liquid environment and improves the separation efficiency.

[0032] In the above embodiments, see Figure 3 , 4The guiding mechanism 4 includes a limiting plate 401, a guiding tube 402, a retaining ring 403, an exhaust port 404, a partition net 405, and a pressure cap 406. The limiting plate 401 is detachably connected to the inner wall of the protective shell 101 and is located at the top of the limiting ring 102. The guiding tube 402 is fixedly installed at the top of the limiting plate 401. The retaining ring 403 is fixedly installed above the inner wall of the guiding tube 402. Multiple exhaust ports 404 are respectively opened above the outer surface of the guiding tube 402. The partition net 405 is detachably installed above the inner wall of the guiding tube 402 and is located above the retaining ring 403. The pressure cap 406 is threadedly connected to the upper part of the inner wall of the guiding tube 402. The limiting plate 401 is detachably connected to the inner wall of the protective shell 101 to fix the guiding tube 402 and separate the internal space of the protective shell 101, dividing the interior of the protective shell 101 into upper and lower cavities. At the same time, it provides an installation base for the support rod 503 of the diversion mechanism 5 to ensure structural stability. The guide tube 402 is fixed to the top of the limiting plate 401, guiding the liquid downwards and providing a channel for gas-liquid separation. The pipe structure constrains the liquid flow direction, preventing disorderly diffusion during separation and enhancing controllability. The retaining ring 403 is fixed to the upper inner wall of the guide tube 402, supporting the mesh 405 and limiting its position to prevent displacement under liquid impact. This ensures the mesh 405 stably performs its secondary gas-liquid separation function. The exhaust port 404 is located above the outer surface of the guide tube 402, providing an upward flow channel for gas. This allows gas entrained in the liquid to escape through the exhaust port 404, achieving initial gas-liquid separation and reducing residual gas in the liquid. The mesh 405 is detachably installed on the upper inner wall of the guide tube 402, performing secondary filtration and separation on the gas-liquid mixture passing through the guide tube 402. This further intercepts tiny bubbles and impurities in the liquid, improving the precision of gas-liquid separation while slowing the liquid flow rate to facilitate gas escape. The gland 406 is threaded onto the upper inner wall of the guide tube 402, pressing the mesh 405 and sealing the top of the guide tube 402, ensuring that the mesh 405 is firmly installed and preventing liquid from leaking from the gap at the top of the guide tube 402. At the same time, the threaded structure enables quick disassembly and assembly, facilitating the maintenance of the mesh 405.

[0033] In the above embodiments, see Figure 4 and Figure 7The diversion mechanism 5 also includes support rods 503 and guide holes 504. Multiple support rods 503 are fixedly installed on the diversion plate 501. The bottom ends of the multiple support rods 503 are inserted into the top of the limiting plate 401. One end of the support rod 503 that extends out of the limiting plate 401 is threaded with a fixing bolt. The guide hole 504 is opened at the center of the top of the diversion plate 501. The piston 601 is slidably connected to the inner wall of the guide hole 504 and fixed to the top of the diversion plate 501 by the support rods 503. The bottom end is inserted into the limiting plate 401 and locked by the fixing bolt, so that the diversion plate 501 is stably supported above the guiding mechanism 4, ensuring that it does not shift under liquid impact. At the same time, the detachable design makes it easy to adjust the height of the diversion plate 501 or replace it. The guide hole 504 is opened at the center of the top of the diversion plate 501, providing a sliding channel for the piston 601 of the backflush mechanism 6, so as to achieve precise sliding with the piston 601, ensuring the directional flow of gas during backflush and improving the working stability of the backflush mechanism 6.

[0034] In the above embodiment, the backflushing mechanism 6 further includes a guide groove 602, a guide block 603, and a limiting bolt 604. Multiple guide grooves 602 are respectively opened on the outer wall of the piston 601. Multiple guide blocks 603 are respectively fixedly installed on the inner side wall of the guide hole 504 and are slidably connected to the inner wall of the guide groove 602. The limiting bolt 604 is threadedly connected to one end of the piston 601 that penetrates the guide plate 501. The guide groove 602 is opened on the outer wall of the piston 601. The guide block 603 is fixed to the inner side wall of the guide hole 504 and slidably connected to the guide groove 602, limiting the sliding direction of the piston 601 and preventing it from rotating or deviating during sliding, ensuring the stability of the gas passage during backflushing. The limiting bolt 604 is threadedly connected to one end of the piston 601 that penetrates the guide plate 501, limiting the maximum stroke of the piston 601 upward and preventing it from falling out of the guide hole 504. At the same time, the threaded structure enables quick disassembly and maintenance of the piston 601.

[0035] In the above embodiment, a drain pipe 7 is inserted into the outer surface of the protective shell 101. One end of the drain pipe 7 is inserted into the protective shell 101 and is located above the limiting disk 401. The drain pipe 7 is inserted into the outer surface of the protective shell 101 and the insertion end is located above the limiting disk 401. It serves as a discharge channel for the separated liquid, directing the liquid separated by the diversion and guiding mechanism 4 to avoid the liquid from accumulating in the protective shell 101 and ensuring that the separated liquid quickly enters the subsequent processing stage.

[0036] The working process of using this embodiment to perform a gas-liquid separator on a liquid collection tank is as follows:

[0037] I. Liquid Inlet and Preliminary Filtration Stage:

[0038] The gas-liquid mixture enters the separator through the inlet pipe 202 of the liquid inlet mechanism 2. When it flows through the filter screen 204 between the upper cover 201 and the protective shell 101, the filter screen 204 intercepts solid impurities in the mixture, achieving preliminary filtration. The filtered gas-liquid mixture then flows downward into the internal cavity of the protective shell 101.

[0039] II. Separation and Preliminary Gas-Liquid Separation Stage:

[0040] When the gas-liquid mixture falls onto the guide plate 501 of the diversion mechanism 5, the guide plate 501 guides the liquid to the surrounding areas, preventing the liquid from directly impacting the guide mechanism 4 below. The liquid flows downward through the drain holes 502 around the guide plate 501. During the flow, due to the increased dispersion contact area, some gas separates from the liquid, achieving initial separation. At the same time, when the air pressure above the guide plate 501 fluctuates, the drain holes 502 assist the liquid to pass through quickly.

[0041] III. Guiding and Deep Gas-Liquid Separation Stage:

[0042] Liquid flowing down through drain hole 502 enters guide tube 402 of guide mechanism 4 and flows downward under the constraint of guide tube 402. When the liquid flows through partition 405, partition 405 further intercepts tiny air bubbles and residual impurities, while slowing down the liquid flow rate to facilitate gas escape. Vent hole 404 on the outer surface of guide tube 402 provides an upward channel for gas entrained in the liquid. Gas escapes from the liquid through vent hole 404, achieving deep separation. Cover 406 presses the partition 405 to ensure its stable separation function and prevents liquid from leaking from the top gap of guide tube 402.

[0043] IV. Gas-liquid separation and discharge stage:

[0044] The separated gas rises through the exhaust port 404 of the guide pipe 402 and is finally discharged through the exhaust pipe 302 of the exhaust mechanism 3 at the bottom of the protective shell 101. The separated liquid continues to flow downward along the guide pipe 402. After reaching the limit plate 401, it is discharged directionally into the collection tank through the drain pipe 7 on the outer surface of the protective shell 101.

[0045] V. Backflushing and cleaning stage:

[0046] When impurities accumulate on the surface of the filter screen 204 and need to be cleaned, the piston 601 slides upward along the guide hole 504 of the guide plate 501. The limit bolt 604 limits the maximum stroke of the piston 601 to prevent it from falling off. During the upward movement of the piston 601, the gas flows upward through the exhaust groove 605 on the outer wall of the piston 601, forming a reverse airflow, which blows and washes the filter screen 204 of the liquid inlet mechanism 2, so that the adsorbed impurities are separated from the filter screen 204 to avoid clogging. After cleaning, the piston 601 moves downward to reset, without affecting the normal gas-liquid separation process.
