Description

Technical Field

[0001] This utility model relates to the technical field of bromine production equipment, specifically a multi-stage bromine dehumidification device. Background Technology

[0002] Bromine is the only non-metallic element that is liquid at room temperature. It is a dark reddish-brown liquid with a pungent odor. During the production and purification of bromine, it often contains a certain amount of moisture. The presence of moisture affects the quality of bromine and its subsequent use. Therefore, dehumidification treatment is necessary for bromine.

[0003] Most existing bromine dehumidification devices have simple structures and typically employ a single dehumidification method, resulting in limited dehumidification effectiveness and difficulty in reducing the moisture content of bromine to a low level. Furthermore, the contact between bromine and the desiccant is insufficient during the dehumidification process, leading to low dehumidification efficiency. Additionally, problems such as inconvenient desiccant replacement may arise, increasing production costs and operational complexity.

[0004] Therefore, it is necessary to provide a bromine multi-stage dehumidification device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a bromine multi-stage dehumidification device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bromine multi-stage dehumidification device, comprising:

[0008] A dehumidifier has symmetrically distributed support legs fixedly installed on both sides of its bottom. A drying tower is fixedly embedded in the top of the dehumidifier, and a feed pipe is fixedly inserted in the top of the drying tower. An inner box is fixedly installed on the lower side of one side of the dehumidifier, and a drying box is set inside the inner box. A barrier net is fixedly embedded in the bottom of the drying box.

[0009] A conduit is fixedly connected between the bottom of the drying tower and the top of the inner box. An external exhaust pipe is fixedly installed at the bottom of the inner box, and one end of the external exhaust pipe passes through the dehumidification tank and extends to the bottom of the dehumidification tank.

[0010] A first electric valve is provided on the upper side of the conduit. A drain pipe is fixedly installed on the outer wall of the conduit above the first electric valve. One end of the drain pipe passes through the dehumidifier and extends to the outside of the dehumidifier. A second electric valve is provided on the drain pipe.

[0011] Preferably, a fixed window corresponding to the position of the inner chamber is provided on the lower side of the other side of the dehumidifier. A horizontal rail is fixedly installed on the other side of the dehumidifier below the fixed window. An adjusting screw is rotatably installed inside the horizontal rail. An adjusting block is sleeved on the outer wall of the adjusting screw and is slidably installed on the horizontal rail. A support arm is fixedly installed on the top of the adjusting block. A sealing cover is fixedly installed at one end of the support arm and is fixedly connected to one side of the drying box. A sealing opening adapted to the sealing cover is provided on the side of the inner chamber near the fixed window. A first servo motor is fixedly installed on one side of the horizontal rail, and the drive end of the first servo motor passes through the horizontal rail and extends into the interior of the horizontal rail and is fixedly connected to one end of the adjusting screw.

[0012] Preferably, a horizontal stirring shaft is rotatably installed inside the drying tower, and several vertical stirring rollers are fixedly installed on the outer wall of the horizontal stirring shaft. A second servo motor is fixedly installed on one side of the drying tower, and the drive end of the second servo motor passes through the drying tower and extends into the interior of the drying tower and is fixedly connected to one end of the horizontal stirring shaft.

[0013] Preferably, the dehumidifier has a viewing window on the front, and the drying tower is made of a transparent material.

[0014] Preferably, the adjusting block has a threaded hole that matches the adjusting screw, and the adjusting block is threadedly connected to the adjusting screw through the threaded hole.

[0015] Preferably, the inner wall of the sealing opening is stepped, and a sealing gasket is provided on the inner wall of the sealing opening.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model integrates different dehumidification methods based on various principles to achieve multi-stage dehumidification of bromine through the coordinated use of a dehumidification tank, support legs, a visualization window, a feed pipe, a drying chamber, a conduit, an inner chamber, an outer discharge pipe, a barrier mesh, a drying tower, a first electric valve, a second electric valve, and a drain pipe. First, the bromine is brought into contact with concentrated sulfuric acid, utilizing the strong hygroscopic properties of the sulfuric acid to remove most of the moisture. Then, the hydrated sulfuric acid is discharged through stratification based on density differences. Next, the partially dried bromine passes through a drying chamber filled with anhydrous calcium chloride and molecular sieves to deeply adsorb residual moisture. Finally, it is filtered and discharged through the barrier mesh. This multi-stage dehumidification effectively reduces the moisture content of the bromine to a low level, avoiding the limitations of single dehumidification methods, effectively ensuring the quality of the bromine, and meeting relevant production and usage requirements.

[0018] 2. This utility model utilizes a combination of a sealing cover, support arm, adjusting block, first servo motor, horizontal rail, adjusting screw, and sealing port. When using anhydrous calcium chloride and molecular sieves for bromine dehumidification, the molecular sieve needs regeneration, the anhydrous calcium chloride needs periodic replacement, and the device must be stopped when replacing the desiccant in the drying chamber. This design allows the drying chamber to be moved out of the dehumidification tank through the sealing port and fixed window. This design greatly facilitates desiccant replacement, is highly practical, avoids complex internal operations, effectively reduces operational difficulty, and decreases labor and replacement time costs, thereby lowering overall production costs.

[0019] 3. This utility model utilizes the combined use of a vertical stirring roller, a second servo motor, and a horizontal stirring shaft. The rotation of the vertical stirring roller ensures that the bromine and concentrated sulfuric acid in the drying tower are thoroughly stirred. Through this mechanical stirring action, the contact area and contact frequency between the bromine and the concentrated sulfuric acid, which serves as a dehumidifier, are significantly increased, thereby greatly improving the dehumidification efficiency and effectively shortening the time required for the entire dehumidification process.

[0029] Please see Figures 1-4 One embodiment provided by this utility model:

[0030] A bromine multi-stage dehumidification device, comprising:

[0031] The dehumidifier 1 has symmetrically distributed support legs 2 fixedly installed on both sides of the bottom of the dehumidifier 1. The top of the dehumidifier 1 is fixedly embedded with a drying tower 18. The top of the drying tower 18 is fixedly inserted with a feed pipe 4. The bottom of one side of the dehumidifier 1 is fixedly installed with an inner box 14. The inner box 14 is equipped with a drying box 6. The bottom of the drying box 6 is fixedly embedded with a barrier net 17.

[0032] A conduit 13 is fixedly connected between the bottom of the drying tower 18 and the top of the inner box 14. An external discharge pipe 16 is fixedly installed at the bottom of the inner box 14, and one end of the external discharge pipe 16 passes through the dehumidification tank 1 and extends to the bottom of the dehumidification tank 1.

[0033] A first electric valve 21 is provided on the upper side of the conduit 13. A drain pipe 23 is fixedly installed on the outer wall of the conduit 13 above the first electric valve 21. One end of the drain pipe 23 passes through the dehumidifier tank 1 and extends to one side outside the dehumidifier tank 1. A second electric valve 22 is provided on the drain pipe 23.

[0034] A fixed window 5 corresponding to the position of the inner box 14 is provided on the lower side of the other side of the dehumidifier tank 1. A horizontal rail 11 is fixedly installed on the other side of the dehumidifier tank 1 below the fixed window 5. An adjusting screw 12 is rotatably installed inside the horizontal rail 11. An adjusting block 9 is sleeved on the outer wall of the adjusting screw 12 and is slidably installed on the horizontal rail 11. A support arm 8 is fixedly installed on the top of the adjusting block 9. A sealing cover 7 is fixedly installed on one end of the support arm 8 and is fixedly connected to one side of the drying box 6. A sealing port 15 adapted to the sealing cover 7 is provided on the side of the inner box 14 near the fixed window 5. A first servo motor 10 is fixedly installed on one side of the horizontal rail 11 and the drive end of the first servo motor 10 passes through the horizontal rail 11 and extends into the interior of the horizontal rail 11 and is fixedly connected to one end of the adjusting screw 12.

[0035] In one embodiment, a horizontal stirring shaft 24 is rotatably installed inside the drying tower 18, and several vertical stirring rollers 19 are fixedly installed on the outer wall of the horizontal stirring shaft 24. A second servo motor 20 is fixedly installed on one side of the drying tower 18, and the drive end of the second servo motor 20 passes through the drying tower 18 and extends into the interior of the drying tower 18 and is fixedly connected to one end of the horizontal stirring shaft 24. This allows for thorough stirring of the bromine and concentrated sulfuric acid inside the drying tower 18, ensuring that the bromine and concentrated sulfuric acid, which serve as a dehumidifier, come into full contact. This improves dehumidification efficiency, shortens dehumidification time, and enhances the overall dehumidification process.

[0036] In one preferred embodiment, the dehumidifier tank 1 is provided with a visualization window 3 on the front, and the drying tower 18 is made of a transparent material for visualization, so that the operator can observe the bromine dehumidification process and the status of the dehumidifier in the dehumidifier tank 1 and the drying tower 18 in real time, so as to discover and deal with problems in time, and ensure the stable operation of the equipment and the dehumidification effect.

[0037] In one embodiment, the adjusting block 9 has a threaded hole that matches the adjusting screw 12, and the adjusting block 9 is threadedly connected to the adjusting screw 12 through the threaded hole, which can convert the rotation of the adjusting screw 12 into a smooth linear movement of the adjusting block 9, ensuring that the operation of changing the desiccant in the drying box 6 is accurate and reliable.

[0038] In one preferred embodiment, the inner wall of the sealing port 15 is stepped, and a sealing gasket is provided on the inner wall of the sealing port 15 to enhance the sealing effect, prevent bromine leakage, ensure the safe operation of the device, and improve dehumidification efficiency.

[0039] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer for control, and existing publicly available power connection technologies are not detailed here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. In use, a suitable amount of concentrated sulfuric acid is first precisely added to the drying tower 18 through the feed pipe 4. After the concentrated sulfuric acid is added, bromine is introduced into the drying tower 18 at a slow and stable flow rate, ensuring full contact with the concentrated sulfuric acid. During this process, the concentrated sulfuric acid, due to its strong hygroscopic properties, rapidly absorbs most of the water in the bromine. Subsequently, due to the density difference between bromine and sulfuric acid, they naturally separate into layers. At this point, by precisely controlling the opening of the first electric valve 21, the lower layer of preliminarily dried bromine enters the drying chamber 6 under the guidance of the conduit 13. Concentrated sulfuric acid containing moisture can be discharged from the drain pipe 23 by closing the first electric valve 21 and opening the second electric valve 22. The drying chamber 6 is pre-filled with strictly screened anhydrous calcium chloride and molecular sieves with suitable pore sizes. When the bromine that has undergone primary dehumidification slowly passes through at a suitable flow rate, the anhydrous calcium chloride and molecular sieves utilize their own physical adsorption properties to deeply adsorb the residual moisture in the bromine, thereby further reducing the moisture content of the bromine. After multi-stage dehumidification, the bromine continues to flow and finally flows into the external drain pipe 16 and is discharged from the device after being filtered by the barrier screen 17. This device achieves multi-stage dehumidification of bromine by integrating dehumidification methods based on different principles, effectively reducing the moisture content of the bromine to a low level and strongly ensuring the quality of the bromine.

[0040] In the process of dehumidifying bromine using anhydrous calcium chloride and molecular sieves, the molecular sieves require regeneration after a certain period of use, and the anhydrous calcium chloride loses its drying efficiency after absorbing a certain amount of moisture and needs to be replaced periodically. Therefore, when it is necessary to replace the desiccant in the drying chamber 6, the device must be stopped. At this time, the first servo motor 10 can be started. The drive end of the first servo motor 10 drives the adjusting screw 12 to rotate. Through the threaded transmission between the adjusting screw 12 and the adjusting block 9, and the sliding cooperation between the adjusting block 9 and the horizontal rail 11, the adjusting block 9 is moved smoothly in the lateral direction. The movement of the adjusting block 9 drives the sealing cover 7 to move synchronously through the support arm 8, which in turn moves the drying chamber 6, allowing the drying chamber 6 to pass through the sealing port 15 and the fixed window 5 and be removed from the dehumidification tank 1. This design greatly facilitates the replacement of the desiccant in the drying chamber 6, has high practicality, and effectively reduces the difficulty of operation and production costs.

[0041] During the stage where bromine contacts concentrated sulfuric acid and undergoes a dehumidification reaction within the drying tower 18, the second servo motor 20 can be activated. The drive end of the second servo motor 20 rotates the horizontal stirring shaft 24, and based on the rotation of the horizontal stirring shaft 24, the vertical stirring roller 19 connected to it rotates synchronously. The rotation of the vertical stirring roller 19 ensures that the bromine and concentrated sulfuric acid within the drying tower 18 are thoroughly stirred. Through this mechanical stirring action, the contact area and contact frequency between the bromine and the concentrated sulfuric acid, which serves as a dehumidifying agent, can be significantly increased, thereby greatly improving the dehumidification efficiency and effectively shortening the time required for the entire dehumidification process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
