Abstract
Description
Technical Field
[0001] This application relates to the field of gas-liquid separation equipment technology, and in particular to a gas-water separator. Background Technology
[0002] The compressed air used in the electrolytic cell contains a small amount of moisture, which can affect the service life of the equipment. Currently, this moisture is discharged through the electronic drain valve of the gas-water separator at the bottom of the cell. However, over time, rust accumulates in the pipes and enters the gas-water separator. The rust accumulates in the gas-water separator, causing the valve core of the electronic drain valve to become stuck. This results in frequent air release and waste of compressed air when the electric drain valve is used for drainage.
[0003] In the relevant technical field, a filter screen is now installed before the electronic drain valve pipeline to filter rust and clean it regularly, but the steam-water separator needs to be shut down when cleaning. Utility Model Content
[0004] This application provides a steam-water separator that can reduce gas leakage when the steam-water separator discharges water.
[0005] The gas-water separator includes a gas-water separation component and a drainage component. The gas-water separation component has a gas-water separation chamber. The drainage component includes a liquid collecting element, a sealing ring, a filter screen, and a drain valve. The liquid collecting element is connected to the gas-water separation component and has a liquid collecting chamber communicating with the gas-water separation chamber. The liquid collecting element has a first disassembly opening communicating with the liquid collecting chamber. The sealing ring is rotatably sleeved on the surface of the liquid collecting element and has a second disassembly opening communicating with the first disassembly opening. When the first disassembly opening and the second disassembly opening are at least partially connected, the filter screen can be inserted into the liquid collecting chamber through the first disassembly opening and the second disassembly opening. When the first disassembly opening and the second disassembly opening are misaligned, the sealing ring seals the first disassembly opening. The drain valve is connected to the bottom end of the liquid collecting element and communicates with the liquid collecting chamber.
[0006] Based on the gas-water separator of this application embodiment, when the user cleans the filter screen, the sealing ring is rotated to make the first disassembly opening and the second disassembly opening at least partially overlap, so as to remove the filter screen from the first disassembly opening and the second disassembly opening. Then, the sealing ring is immediately rotated to make the first disassembly opening and the second disassembly opening misaligned, so that the sealing ring seals the first disassembly opening. During this process, only a small amount of gas-water mixture or liquid flows out from the first disassembly opening and the second disassembly opening. After the filter screen is cleaned, the first sealing ring is rotated again to make the first disassembly opening and the second disassembly opening at least partially overlap to insert the filter screen. Then, the sealing ring is immediately rotated to make the first disassembly opening and the second disassembly opening misaligned, so that the sealing ring re-seals the first disassembly opening. This allows the gas-water separator to replace the filter screen without stopping the machine.
[0007] In some embodiments of this application, the filter screen includes an elastic frame and a soft mesh body, the elastic frame being capable of elastic deformation; the edges of the soft mesh body are fixed to the elastic frame.
[0008] Based on the above embodiments, the liquid collection component can have a smaller first disassembly and assembly opening. When the filter screen is installed into the liquid collection chamber, the elastic frame deforms and the soft mesh shrinks so that the filter screen can pass through the first disassembly and assembly opening. After the filter screen is installed into the liquid collection chamber, the elastic frame restores its deformation so that the filter screen adheres tightly to the inner wall of the liquid collection chamber.
[0009] In some embodiments of this application, the number of the soft mesh body is at least two, and the at least two soft mesh bodies are stacked; the filter screen also includes magnetic blocks, which are disposed between adjacent soft mesh bodies.
[0010] Based on the above embodiments, the magnetic block enables the filter screen to better filter magnetic impurities, such as rust that often occurs in pipelines.
[0011] In some embodiments of this application, a limiting ring is provided on the inner wall of the liquid collection chamber, and the elastic frame is located below the limiting ring and abuts against the limiting ring along the height direction of the gas-water separator.
[0012] Based on the above embodiments, after the filter screen is installed into the liquid storage cavity through the first disassembly opening, the elastic frame begins to recover its deformation. After the elastic frame recovers its deformation, the limiting ring can position the elastic frame so that the elastic frame is in a suitable position.
[0013] In some embodiments of this application, the outer surface of the liquid collecting element has a positioning groove for the first disassembly opening, the filter screen further includes a positioning part, the positioning part is connected to the elastic frame and is located inside the positioning part, and the sealing ring presses against the positioning part to make the positioning part and the bottom wall of the positioning groove make sealed contact.
[0014] Based on the above embodiments, after the filter screen is in the liquid collection chamber, since the positioning part is outside the liquid collection chamber and cooperates with the positioning groove to restrict the elastic frame, the elastic frame basically remains in a fixed position after restoring its deformation in the liquid collection chamber, and the positioning part and the groove wall of the positioning groove are in sealed contact, which further improves the sealing performance of the liquid collection component.
[0015] In some embodiments of this application, the liquid collecting component further includes a sealing gasket located between the positioning portion and the bottom wall of the positioning groove, and the sealing ring has a pressure surface that is gradually moved away from the center of the sealing ring along its circumference.
[0016] Based on the above embodiments, during the rotation of the sealing ring, the pressure surface gradually applies pressure to the positioning part to squeeze the sealing gasket, thereby enhancing the sealing between the positioning part and the bottom wall of the positioning groove to ensure the sealing performance of the steam-water separator.
[0017] In some embodiments of this application, the filter screen is positioned close to the drain valve.
[0018] Based on the above embodiments, the filter screen is located close to the drain valve, that is, the filter screen is located at the bottom of the liquid collection chamber. In this way, when the filter screen is replaced, the liquid in the liquid collection chamber will flow out of the liquid collection chamber through the first disassembly opening and the second disassembly opening, thus preventing the loss of compressed gas in the gas-water separator.
[0019] In some embodiments of this application, the drain valve is an electrically controlled valve, and the drainage assembly further includes a liquid level detection element, which is installed in the liquid collection chamber and electrically connected to the electrically controlled valve.
[0020] Based on the above embodiments, after the liquid level in the liquid collection chamber touches the liquid level detection device, the liquid level detection device sends a signal to the solenoid valve, and the solenoid valve automatically connects to discharge the liquid in the liquid collection chamber.

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0029] The compressed air used in the electrolytic cell contains a small amount of moisture, which can affect the service life of the equipment. Currently, this moisture is discharged through the electronic drain valve of the gas-water separator at the bottom of the cell. However, over time, rust accumulates in the pipes and enters the gas-water separator. The rust accumulates in the gas-water separator, causing the valve core of the electronic drain valve to become stuck. This results in frequent air release and waste of compressed air when the electric drain valve is used for drainage.
[0030] In the relevant technical field, a filter screen is now installed before the electronic drain valve pipeline to filter rust and clean it regularly, but the steam-water separator needs to be shut down when cleaning.
[0031] To solve the above technical problems, please refer to Figures 1 to 3 As shown, the first aspect of this application proposes a steam-water separator that can reduce gas leakage when the steam-water separator discharges water.
[0032] Please refer to Figures 1 to 3 As shown, the steam-water separator includes a steam-water separation component 10 and a drainage component 20. The steam-water separation component 10 has a steam-water separation chamber. The drainage component 20 includes a liquid collecting element 21, a sealing ring 22, a filter screen 23, and a drain valve 24. The liquid collecting element 21 is connected to the steam-water separation component 10 and has a liquid collecting chamber 211 communicating with the steam-water separation chamber. The liquid collecting element 21 has a first disassembly and assembly opening 212 communicating with the liquid collecting chamber 211. The sealing ring 22 is rotatably sleeved on the surface of the liquid collecting element 21. It has a second disassembly opening 221 that can connect to the first disassembly opening 212; when the first disassembly opening 212 and the second disassembly opening 221 are at least partially connected, the filter screen 23 can be installed into the liquid collection chamber 211 through the first disassembly opening 212 and the second disassembly opening 221; when the first disassembly opening 212 and the second disassembly opening 221 are misaligned, the sealing ring 22 seals the first disassembly opening 212; the drain valve 24 is connected to the bottom end of the liquid collection component 21 and communicates with the liquid collection chamber 211.
[0033] The mixture of steam and water is separated into gas and liquid in the steam-water separation component 10. The gas will be discharged from the steam-water separator, and the liquid and impurities in the steam-water separator will be collected in the liquid collection component 21. The filter screen 23 can filter the impurities in the liquid so that the drain valve 24 can be opened or closed normally. It can be understood that the drain valve 24 is fixed at the bottom of the liquid collection component 21. When the drain valve 24 is opened, all the liquid in the liquid collection chamber 211 can be discharged.
[0034] The liquid collector will be used to store the liquid separated from the soda-water mixture. Immediately, in order to fit the sealing ring 22, at least part of the outer surface of the liquid collector 21 in this embodiment needs to be configured as an annular surface.
[0035] Based on the gas-water separator of this application embodiment, when the user cleans the filter screen 23, the sealing ring 22 is rotated to make the first disassembly opening 212 and the second disassembly opening 221 at least partially overlap, so that the filter screen 23 can be removed from the first disassembly opening 212 and the second disassembly opening 221. Then, the sealing ring 22 is immediately rotated to make the first disassembly opening 212 and the second disassembly opening 221 misaligned, so that the sealing ring 22 seals the first disassembly opening 212. During this process, only a small amount of gas-water mixture or liquid flows out from the first disassembly opening 212 and the second disassembly opening 221. After the filter screen 23 is cleaned, the first sealing ring 22 is rotated again to make the first disassembly opening 212 and the second disassembly opening 221 at least partially overlap to insert the filter screen 23. Then, the sealing ring 22 is immediately rotated to make the first disassembly opening 212 and the second disassembly opening 221 misaligned, so that the sealing ring 22 seals the first disassembly opening 212 again, so that the gas-water separator can replace the filter screen 23 without stopping the machine.
[0036] Please refer to Figure 3 As shown, in some embodiments of this application, the filter screen 23 includes an elastic frame 231 and a soft mesh 232, the elastic frame 231 being capable of elastic deformation; the edge of the soft mesh 232 is fixed to the elastic frame 231.
[0037] The liquid collecting component 21 can have a smaller first disassembly and assembly opening 212. When the filter screen 23 is installed into the liquid collecting cavity 211, the elastic frame 231 deforms and the soft mesh body 232 contracts so that the filter screen 23 can pass through the first disassembly and assembly opening 212. After the filter screen 23 is installed into the liquid collecting cavity 211, the elastic frame 231 restores its deformation so that the filter screen 23 is close to the inner wall of the liquid collecting cavity 211.
[0038] The elastic frame 231 in this embodiment can be formed by bending steel wire. The steel wire not only has good elasticity but also generates a large elastic force after deformation, which is beneficial for the elastic frame 231 to recover its deformation in the liquid collection cavity 211.
[0039] Since the soft mesh 232 needs to be bent during the assembly and disassembly of the filter screen 23, the soft mesh 232 in this embodiment can be configured as a fiber mesh, nylon mesh, or fabric, etc.
[0040] Please refer to Figure 3 As shown, in some embodiments of this application, the number of soft mesh bodies 232 is at least two, and at least two soft mesh bodies 232 are stacked; the filter screen 23 also includes a magnetic block 233, which is disposed between adjacent soft mesh bodies 232. The magnetic block 233 enables the filter screen 23 to better filter magnetic impurities, such as rust that often occurs in pipelines. In the embodiments of this application, the magnetic block 233 is configured as a permanent magnet.
[0041] Please refer to Figure 4 As shown, in some embodiments of this application, a limiting ring 213 protrudes from the inner wall of the liquid collection chamber 211. The elastic frame 231 is located below and abuts against the limiting ring 213 along the height direction a of the gas-water separator. After the filter screen 23 is installed into the liquid storage chamber through the first disassembly opening 212, the elastic frame 231 begins to recover its deformation. After the elastic frame 231 recovers its deformation, the limiting ring 213 can position the elastic frame 231 so that the elastic frame 231 is in a suitable position.
[0042] Please refer to Figure 2 As shown in some embodiments of this application, the outer surface of the liquid collecting component 21 has a positioning groove 214 with a first disassembly opening 212. The filter screen 23 also includes a positioning part 234, which is connected to the elastic frame 231 and located within the positioning part 234. The sealing ring 22 presses against the positioning part 234 to make the positioning part 234 and the bottom wall of the positioning groove 214 make a sealing contact. After the filter screen 23 is in the liquid collecting cavity 211, since the positioning part 234 is outside the liquid collecting cavity 211 and cooperates with the positioning groove 214, it can restrict the elastic frame 231, so that the elastic frame 231 basically remains in a fixed position after restoring its deformation in the liquid collecting cavity 211. Furthermore, the positioning part 234 and the groove wall of the positioning groove 214 make a sealing contact, which further improves the sealing performance of the liquid collecting component 21.
[0043] Please refer to Figure 2 and Figure 5 As shown, in some embodiments of this application, the liquid collecting member 21 further includes a sealing gasket (not shown in the figure). The sealing gasket is located between the positioning part 234 and the bottom wall of the positioning groove 214. The sealing ring 22 has a pressure surface 222. The pressure surface 222 is arranged gradually away from the center of the sealing ring 22 along the circumference of the sealing ring 22. During the rotation of the sealing ring 22, the pressure surface 222 gradually applies pressure to the positioning part 234 to squeeze the sealing gasket, thereby enhancing the sealing between the positioning part 234 and the bottom wall of the positioning groove 214, so as to ensure the sealing performance of the steam-water separator.
[0044] In some embodiments of this application, the filter screen 23 is positioned close to the drain valve 24, that is, the filter screen 23 is positioned at the bottom of the liquid collection chamber 211. In this way, when the filter screen 23 is replaced, the liquid in the liquid collection chamber 211 will flow out of the liquid collection chamber 211 through the first disassembly opening 212 and the second disassembly opening 221. Thus, the compressed gas in the gas-liquid separator will not be lost. Combined with the above-mentioned filter screen 23 abutting against the limiting ring 213, the corresponding limiting ring 213 is also positioned at the bottom of the liquid collection chamber 211.
[0045] In some embodiments of this application, the drain valve 24 is an electrically controlled valve, and the drainage assembly 20 also includes a liquid level detection element 25, which is installed in the liquid collection chamber 211 and electrically connected to the electrically controlled valve.
[0046] After the liquid level in the liquid collecting chamber 211 touches the liquid level detection element 25, the liquid level detection element 25 sends a signal to the solenoid valve, and the solenoid valve automatically connects to discharge the liquid in the liquid collecting chamber 211.
