Description

Technical Field

[0001] This invention relates to an electrolyte regeneration device, and more particularly to an electrolyte dissolution and regeneration reaction device for electrolytic fluorine production. Background Technology

[0002] Industrially, fluorine gas is produced by electrolyzing anhydrous hydrogen fluoride (HF). The electrolyte is a molten mixture (KF·2HF) made from potassium hydrogen fluoride (KHF2, containing 20.4% HF) and anhydrous hydrogen fluoride (HF). During electrolysis, the electrolyte solution corrodes the electrolytic cell and its components, causing perforations and water ingress into the inner wall. Corrosion of the electrolytic cell leads to excessive impurities in the electrolyte solution, resulting in electrolyte aging. Side reactions or impurity accumulation in the electrolyte can occur, leading to an imbalance in the proportion of effective components, directly affecting current efficiency and the purity of fluorine products. If the electrolyte is not replaced in time, irreversible electrode damage may occur due to impurity accumulation. Therefore, the electrolyte needs to be replaced after a period of use. In traditional processes, the replaced electrolyte is directly treated externally, which is not only costly to recover but also wastes a large amount of useful materials.

[0003] In the traditional process of regenerating electrolyte, an alkali is added to dissolve the electrolyte solution, and the reacted electrolyte solution is filtered. The filtered product is then crystallized and dried. In the regeneration dissolution process, the existing technology first crushes the waste electrolyte and places it in a water bath to dissolve it. After it is completely dissolved into a liquid, it is transferred to another constant temperature water bath and an appropriate amount of KOH is added to adjust the pH value of the electrolyte solution to 3-5. After the reaction, it is transferred to an aging zone for aging. Throughout the process, in order to avoid contact with metal containers, the solution needs to be continuously transferred from plastic buckets to different environments for reaction. The overall reaction efficiency is very slow, and due to the limited area of ​​the water bath zone, the annual electrolyte processing capacity is limited, and the output can never be increased.

[0004] Therefore, this invention aims to provide an electrolytic fluorine production electrolyte dissolution and regeneration reaction device, which not only avoids metal containers from contacting the equipment and preventing more impurities from entering, but also allows dissolution, reaction, and aging steps to be carried out simultaneously in the same container. This not only improves the overall reaction efficiency, but also makes the overall reaction continuous and increases the yield. Summary of the Invention

[0005] This invention provides an electrolytic fluorine production electrolyte dissolution and regeneration reaction device, which can effectively solve the above-mentioned problems.

[0006] This invention is implemented as follows:

[0007] An electrolytic fluorine production electrolyte dissolution and regeneration reaction device includes: an external dissolution vessel for holding the liquid, a mounting cover on the top of the external dissolution vessel, and an electrolyte feeding hopper, a mother liquor return pipe, and an alkali feeding pipe respectively disposed on the top of the mounting cover; and further includes:

[0008] The inner swirl dissolving tank has a lower swirl frame at the bottom of the inner side of the outer dissolving vessel and an upper swirl frame at the top of the inner side of the outer dissolving vessel. The inner swirl dissolving tank includes a steel-lined PTFE tube movably installed between the lower and upper swirl frames. An outer swirl component is provided on the upper half of the outer side of the steel-lined PTFE tube. The outer swirl component is driven by at least one driving component. The electrolyte, mother liquor, and alkali added through the electrolyte feeding hopper, mother liquor return pipe, and alkali feeding pipe are fully mixed and dissolved in the outer swirl component driven by the driving component.

[0009] The movable steam structure has an opening at the top of the external dissolving vessel. The movable steam structure includes a steam conduit that is movably inserted into the opening. The top end of the steam conduit is connected to an external steam pipe, and the bottom end of the steam conduit is connected to a steam applicator. The outer wall of the steam applicator is in close contact with the inner wall of the PTFE-lined steel tube. When the driving component drives the PTFE-lined steel tube to rotate, the steam applicator provides a counterforce on the inside, and the end of the steam applicator is in close contact with the inner wall of the PTFE-lined steel tube.

[0010] As a further improvement, the lower rotating frame includes a support frame fixed to the inner wall of the outer dissolving vessel. A wrapping ring is fixed to the inner side of the support frame, and a plurality of outer guide wheels are provided on the inner side of the wrapping ring. The outer guide wheels are movably engaged with the outer wall of the steel-lined PTFE tube.

[0011] As a further improvement, the steel-lined PTFE tube includes a steel cylinder, the inner side of which is provided with a PTFE tube liner, and a support edge is provided extending outward from the top of the steel cylinder. The thickness of the PTFE tube liner is greater than that of the steel cylinder.

[0012] As a further improvement, the upper rotating frame includes a bottom guide plate that fits against the lower end of the support edge, and an upper guide plate is provided at the upper end of the support edge. When the steel-lined PTFE tube rotates, it is located in the gap formed by the bottom guide plate and the upper guide plate.

[0013] As a further improvement, the external rotating component includes an external rotating ring disposed on the outside of the steel-lined PTFE tube, and an external rotating gear ring is disposed on the outside of the external rotating ring, the external rotating gear ring being connected via a driving component.

[0014] As a further improvement, the drive unit includes a drive frame disposed on the inner wall of the outer dissolving vessel, the drive frame extending to the bottom surface of the outer rotating ring, an inner liner rotating motor disposed on the drive frame, and a mating gear disposed on the output end of the inner liner rotating motor, the mating gear meshing with the outer rotating gear ring.

[0015] As a further improvement, the steam applicator includes an inner steam support frame located inside the steel-lined PTFE tube. The inner steam support frame and the outer rotating component are located on the same horizontal plane. The inner side of the inner steam support frame is provided with a plurality of steam branch pipes communicating with the steam conduit. The lower end of the steam branch pipes points towards the inner wall of the steel-lined PTFE tube.

[0016] As a further improvement, the outer walls of the inner steam support frame and the steam branch pipe are provided with embedded guide wheels, and the inner steam support frame and the steam branch pipe are movably connected to the inner wall of the steel-lined PTFE tube.

[0017] As a further improvement, a discharge pipe clearance groove is provided on the inner steam support frame, and the electrolyte feeding hopper extends downward and passes through the discharge pipe clearance groove.

[0018] As a further improvement, an inner plastic ring is provided on the inner side of the steel-lined PTFE tube, and the inner steam support frame is embedded in the inner plastic ring.

[0019] The beneficial effects of this invention are:

[0020] Existing technologies require the solution to be continuously transferred through plastic containers to different environments for reaction, resulting in very slow overall reaction efficiency. Furthermore, due to the limited area of ​​the water bath, the annual electrolyte processing capacity is limited, and production output cannot be increased. Therefore, this invention, through the design of an internal swirling dissolution tank, firstly employs a steel-lined PTFE tube, allowing the entire dissolution reaction to take place inside the PTFE-lined tube, avoiding the introduction of new metal impurities. Simultaneously, an external swirling component is installed on the outside of the PTFE-lined tube, allowing the entire rotation to be completed externally, avoiding the direct placement of the stirring equipment inside the PTFE-lined tube. This minimizes the contact between more metals and the electrolyte, thereby ensuring the purity of the regenerated electrolyte.

[0021] The entire PTFE-lined steel tube is quite heavy, both in terms of its own weight and the weight of the electrolyte it carries. To ensure stability while allowing rotation, the lower rotating frame of this invention needs to be supported by a support frame and further supported and guided by a wrapping ring and an outer guide wheel. The rotation of the outer rotating component and the driving component ensures stable rotation at the bottom, thereby ensuring the stability of the inner rotating dissolving tank during rotation.

[0022] Since the entire steel-lined PTFE tube needs to be rotated, the overall weight needs to be reduced. However, in order to avoid electrolyte leakage, the thickness of the PTFE tube lining in this invention remains unchanged, but the thickness of the steel tube is made thinner, thereby reducing the overall weight and making rotation easier.

[0023] If the top surface of the PTFE-lined tube is not guided, it is easy to make it difficult to position the material at the top. Therefore, the present invention sets an upper rotating frame on the top surface of the PTFE-lined tube. The upper guide plate and the bottom guide plate formed by the upper rotating frame restrict the support along a certain area, so that the PTFE-lined tube can maintain linear rotation, thereby ensuring that the PTFE-lined tube can stably cooperate with the moving steam structure and the electrolyte feeding hopper.

[0024] In order to ensure the stability of the meshing effect during the engagement of the driving component and the outer rotating component, this invention not only uses the outer rotating gear ring to engage with the mating gear driven by the inner rotating motor, but also allows the driving frame of the driving component to support the outer rotating ring of the outer rotating component. This can maintain the stability of the lower connecting surface during the meshing process and avoid phenomena such as misalignment.

[0025] While placing the external rotating component outside the PTFE-lined tubing reduces the introduction of metal impurities, the metal portion of the tubing needs to be thinned to facilitate rotation. This thinning reduces the overall strength of the tubing, making it prone to deformation when rotated by the external rotating component. Therefore, this invention incorporates a movable steam structure into the internal rotating dissolving tank. The steam applicator of this movable steam structure not only provides steam heating without contacting the electrolyte solution but also fits snugly against the interior of the PTFE-lined tubing. Positioned at the same level as the external rotating component, the steam applicator supports the inner wall of the tubing, ensuring balance between the inside and outside during rotation, preventing deformation of the tubing, and guaranteeing a stable dissolving reaction.

[0026] The steam applicator not only needs support but also steam conduction. Therefore, the steam applicator of this invention is first provided with an inner steam support frame to provide resistance. In addition, steam branch pipes are provided on the inner side of the inner steam support frame. The inner wall of the steel-lined PTFE tube is heated through several steam branch pipes to first stabilize the temperature of the inner wall of the entire steel-lined PTFE tube and then further raise the temperature of the solution, thereby providing a constant temperature heating or heat preservation effect.

[0027] To prevent some electrolyte from splashing onto the steam dispenser during feeding, the inner steam support frame of this invention has a feed pipe clearance groove, which can extend the feeding path of the electrolyte feed hopper and thus prevent the metal inner steam support frame from contacting the electrolyte solution.

[0028] To ensure the stability of the steam applicator when the PTFE-lined tube rotates, this invention provides an embedded guide wheel on the outside of the steam applicator and an inner plastic ring on the inside of the PTFE-lined tube. This ensures that the position of the steam applicator is always on the inner opposite side of the outer rotating part, thus guaranteeing the force balance of the entire PTFE-lined tube.

The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Reference Figures 1 to 7As shown, an electrolytic fluorine production electrolyte dissolution and regeneration reaction device includes: an external dissolution vessel 10 for holding the liquid, with a mounting cover 11 on the top of the external dissolution vessel 10, and an electrolyte feeding hopper 12, a mother liquor return pipe 13, and an alkali feeding pipe 14 respectively disposed on the top of the mounting cover 11; and an internal swirl dissolution tank 15. A lower swirl frame 101 is disposed at the bottom of the inner side of the external dissolution vessel 10, and an upper swirl frame 102 is disposed at the top inside the external dissolution vessel 10. The internal swirl dissolution tank 15 includes a PTFE-lined steel tube 151 movably installed between the lower swirl frame 101 and the upper swirl frame 102. An external swirl member 152 is disposed on the upper half of the outer side of the PTFE-lined steel tube 151. The external swirl member 152 is driven by at least one driving member 153, and the electrolyte feeding hopper 12 is connected to the external fluorine production electrolyte. The electrolyte, mother liquor, and alkali added to the hopper 12, mother liquor return pipe 13, and alkali addition pipe 14 are fully mixed and dissolved in the external rotating part 152 driven by the drive component 153. A movable steam structure 16 is provided, with an opening at the top of the external dissolution vessel 10. The movable steam structure 16 includes a steam conduit 161 movably inserted into the opening. The top end of the steam conduit 161 is connected to an external steam pipe, and the bottom end of the steam conduit 161 is connected to a steam applicator 162. The outer wall of the steam applicator 162 is tightly attached to the inner wall of the PTFE-lined steel tube 151. When the drive component 153 drives the PTFE-lined steel tube 151 to rotate, the steam applicator 162 provides resistance on the inside, and the end of the steam applicator 162 is tightly attached to the inner wall of the PTFE-lined steel tube 151.

[0042] Existing technologies require the solution to be continuously transferred through plastic containers to different environments for reaction, resulting in very slow overall reaction efficiency. Furthermore, due to the limited area of ​​the water bath, the annual electrolyte processing capacity is limited, and production output cannot be increased. Therefore, this invention, through the design of an inner swirling dissolution tank 15, firstly employs a steel-lined PTFE tube 151, allowing the entire dissolution reaction to take place within the PTFE-lined tube 151, thus avoiding the introduction of new metal impurities. Simultaneously, an outer swirling element 152 is provided on the outside of the PTFE-lined tube 151, enabling the entire rotation to be completed externally. This avoids the stirring equipment being directly placed inside the PTFE-lined tube 151, thereby preventing more metal from coming into contact with the electrolyte and ensuring the purity of the regenerated electrolyte.

[0043] The entire PTFE-lined steel tube 151 is quite heavy, both in terms of its own weight and the weight of the electrolyte it carries. To ensure stability while allowing rotation, the lower rotating frame 101 in this embodiment includes a support frame 1011 fixed to the inner wall of the outer dissolving vessel 10. A wrapping ring 1012 is fixed to the inner side of the support frame 1011, and several outer guide wheels 1013 are provided on the inner side of the wrapping ring 1012. The outer guide wheels 1013 are movably engaged with the outer wall of the PTFE-lined steel tube 151. The lower rotating frame 101 needs to be supported by the support frame 1011 and further supported and guided in a ring shape by the wrapping ring 1012 and the outer guide wheels 1013. Under the rotation of the outer rotating component 152 and the driving component 153, the bottom can be stably rotated, thereby ensuring the stability of the inner rotating dissolving tank 15 in the rotating state.

[0044] Since the entire PTFE-lined steel tube 151 needs to rotate, the overall weight needs to be reduced. However, to prevent electrolyte leakage, the PTFE-lined steel tube 151 in this embodiment includes a steel tube 1511. The inner side of the steel tube 1511 is provided with a PTFE tube liner 1512. A support edge 1513 extends outward from the top of the steel tube 1511. The thickness of the PTFE tube liner 1512 is greater than that of the steel tube 1511. The thickness of the PTFE tube liner 1512 remains unchanged, but the thickness of the steel tube 1511 is made thinner, thereby reducing the overall weight and simplifying the rotation process.

[0045] If the top surface of the PTFE-lined tube 151 is not guided, it is easy to make it difficult to position the material at the top. Therefore, the upper rotating frame 102 in this embodiment includes a bottom guide plate 1021 attached to the lower end of the support edge 1513, and an upper guide plate 1022 is provided at the upper end of the support edge 1513. When the PTFE-lined tube 151 rotates, it is located in the gap formed by the bottom guide plate 1021 and the upper guide plate 1022. The upper rotating frame 102 is provided on the top surface of the PTFE-lined tube 151. The upper guide plate 1022 and the bottom guide plate 1021 formed by the upper rotating frame 102 restrict the support edge 1513 to a certain area, so that the PTFE-lined tube 151 can maintain linear rotation, thereby ensuring that the PTFE-lined tube 151 can stably cooperate with the movable steam structure 16 and the electrolyte feeding hopper 12.

[0046] In order to ensure the stability of the meshing effect during the engagement of the driving component 153 and the external rotating component 152, the external rotating component 152 of the present invention includes an external rotating ring 1521 disposed on the outside of the steel-lined PTFE tube 151. An external rotating gear ring 1522 is disposed on the outside of the external rotating ring 1521. The external rotating gear ring 1522 is connected via the driving component 153. The driving component 153 includes a driving frame 1531 disposed on the inner wall of the outer dissolving vessel 10. The driving frame 1531 extends to the bottom surface of the external rotating ring 1521. An inner liner rotating motor 1532 is provided on 1531. A mating gear 1533 is provided on the output end of the inner liner rotating motor 1532. The mating gear 1533 meshes with the outer rotating gear ring 1522. Not only does the outer rotating gear ring 1522 mesh with the mating gear 1533 driven by the inner liner rotating motor 1532, but the drive frame 1531 of the drive component 153 also supports the outer rotating ring 1521 of the outer rotating component 152. This can maintain the stability of the lower connecting surface during meshing and avoid phenomena such as misalignment.

[0047] Although placing the outer rotating member 152 outside the PTFE-lined tube 151 can reduce the introduction of metal impurities, the metal part of the PTFE-lined tube 151 needs to be thinned to facilitate rotation. After thinning, the overall strength of the PTFE-lined tube 151 is reduced, and the entire tube is prone to deformation when rotated by the outer rotating member 152. Therefore, the present invention sets up a movable steam structure 16 on the basis of the inner rotating dissolving tank 15. The steam applicator 162 of the movable steam structure 16 can not only provide steam heating without contacting the electrolyte solution, but also fits in close contact with the inside of the PTFE-lined tube 151. The steam applicator 162, which is at the same level as the outer rotating member 152, can support the inner wall of the PTFE-lined tube 151, thereby balancing the inside and outside during rotation, avoiding deformation of the PTFE-lined tube 151, and ensuring the stable progress of the dissolving reaction.

[0048] The steam distributor 162 not only needs support but also needs to conduct steam. Therefore, the steam distributor 162 in this embodiment includes an inner steam support frame 1621 located inside the PTFE-lined tube 151. The inner steam support frame 1621 and the outer rotating member 152 are located on the same horizontal plane. The inner side of the inner steam support frame 1621 is provided with a plurality of steam branch pipes 1622 communicating with the steam conduit 161. The lower end of the steam branch pipes 1622 points towards the PTFE-lined tube. The inner wall of the 151 steam applicator 162 is first provided with an inner steam support frame 1621, which provides resistance. A steam branch pipe 1622 is also provided on the inner side of the inner steam support frame 1621. The inner wall of the PTFE-lined steel tube 151 is heated through several steam branch pipes 1622, so that the temperature of the inner wall of the entire PTFE-lined steel tube 151 rises steadily first, and then the temperature of the solution rises further, thereby providing a constant temperature heating or heat preservation effect.

[0049] To prevent some electrolyte from splashing onto the steam applicator 162 during discharging from the electrolyte hopper 12, a discharge pipe clearance groove 1624 is provided on the inner steam support frame 1621 in this embodiment. The electrolyte hopper 12 extends downward and passes through the discharge pipe clearance groove 1624. The discharge pipe clearance groove 1624 on the inner steam support frame 1621 can extend the discharge path of the electrolyte hopper 12, thereby preventing the metal inner steam support frame 1621 from contacting the electrolyte solution.

[0050] To ensure the stability of the steam distributor 162 when the PTFE-lined tube 151 rotates, embedded guide wheels 1623 are provided on the outer walls of the inner steam support frame 1621 and the steam branch pipe 1622 in this embodiment. The inner steam support frame 1621 and the steam branch pipe 1622 are movably connected to the inner wall of the PTFE-lined tube 151. An inner plastic ring 1514 is provided on the inner side of the PTFE-lined tube 151, and the inner steam support frame 1621 is embedded in the inner plastic ring 1514. The embedded guide wheels 1623 are provided on the outer side of the steam distributor 162, and the inner plastic ring 1514 is provided on the inner side of the PTFE-lined tube 151. This ensures that the position of the steam distributor 162 is always on the inner opposite side of the outer rotating part 152, thus ensuring the force balance of the entire PTFE-lined tube 151.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
