[0052] Reference Figure 1 to Figure 7 , which is an embodiment of the present invention, proposes a device for reducing impurity gases in chlorine, comprising: a decomposition tank 1, having a liquid inlet 101 and an exhaust port 102, the liquid inlet 101 is used to pass light salt water, and the exhaust port 102 is used to discharge wet chlorine; a steam coil 2, arranged at the bottom of the inner side of the decomposition tank 1, and the steam coil 2 is used to provide heat required for the decomposition reaction; a drying tower 3, having a concentrated sulfuric acid inlet 302 and a wet chlorine inlet 301, a packing layer 4 is provided in the drying tower 3, and a filler 5 is provided in the packing layer 4, and the filler 5 is used to disperse the concentrated sulfuric acid and wet chlorine; a vibrating member 8, having a power part 85, the power part 85 faces the wet chlorine inlet 301, and after the wet chlorine inlet 301 passes the wet chlorine, the power part 85 drives the vibrating member 8 to move.

[0053] In the above scheme, it is composed of a decomposition tank 1, a steam coil 2, a drying tower 3 and a vibrating member 8. The decomposition tank 1 is provided with a liquid inlet 101 and an exhaust port 102, and the liquid inlet 101 is used to stably pass the light salt water, which can ensure that the light salt water can enter the decomposition tank 1 at a suitable flow rate and pressure. The exhaust port 102 is used to discharge the wet chlorine produced by the reaction, and can ensure that the wet chlorine is discharged smoothly to avoid accumulation in the tank. The steam coil 2 is located at the bottom of the inner side of the decomposition tank 1, and the steam coil 2 is connected to the external heat source system, which can provide continuous and stable heat for the reaction in the decomposition tank 1. The bottom heating method can make the heat evenly distributed in the tank, which is conducive to the full decomposition reaction of the light salt water. The drying tower 3 is a device for realizing chlorine drying and impurity removal, and it is provided with a concentrated sulfuric acid inlet 302 and a wet chlorine inlet 301. The concentrated sulfuric acid inlet 302 is used to introduce high-concentration concentrated sulfuric acid, which can ensure that the concentrated sulfuric acid enters the drying tower 3 at a suitable flow rate. The wet chlorine inlet 301 is a passage for wet chlorine to enter the drying tower 3, which matches the gas flow path of the entire device. The packing layer 4 inside the drying tower 3 is filled with a filler 5, which has good dispersibility and can make concentrated sulfuric acid and wet chlorine fully contact in the packing layer 4. The vibrating member 8 has a power part 85, and the power part 85 faces the wet chlorine inlet 301. When the wet chlorine enters from the inlet, the power part 85 of the vibrating member 8 can be triggered, so that the vibrating member 8 starts to move, thereby providing power support for the operation of the entire device.

[0054] In the actual working process, first, the light salt water enters the decomposition tank 1 from the liquid inlet 101 of the decomposition tank 1. At the same time, the steam coil 2 starts to work, transferring the heat provided by the external heat source to the light salt water in the decomposition tank 1. Under the action of heat, the light salt water undergoes a decomposition reaction to produce wet chlorine. The produced wet chlorine is discharged from the exhaust port 102 of the decomposition tank 1 and enters the wet chlorine inlet 301 of the drying tower 3. At the same time, concentrated sulfuric acid enters from the concentrated sulfuric acid inlet 302 of the drying tower 3. When the wet chlorine enters the wet chlorine inlet 301, the power part 85 of the vibrator 8 is triggered, so that the vibrator 8 starts to move. The action of the vibrator 8 is transmitted to the filler 5 in the packing layer 4 through a certain mechanical structure, so that the filler 5 vibrates. Under the vibration of the filler 5, the concentrated sulfuric acid and the wet chlorine are fully in contact in the packing layer 4. The concentrated sulfuric acid will react chemically with impurities such as moisture in the wet chlorine, thereby achieving preliminary drying of the wet chlorine and removal of impurities. The wet chlorine gas after the preliminary treatment continues to flow upward in the drying tower 3 and contacts with more concentrated sulfuric acid, further improving the drying effect.

[0055] The steam coil 2 is arranged in the decomposition tank 1 to accurately control the reaction temperature, ensure that the decomposition reaction proceeds smoothly and efficiently, and stably produce wet chlorine. This provides a stable raw gas for the subsequent drying and impurity removal process. Secondly, the unique design of the vibrator 8 and the filler 5 in the drying tower 3 breaks the limitation of insufficient contact between concentrated sulfuric acid and wet chlorine in the traditional drying tower 3. The special structure of the filler 5 and the synergistic effect of the vibrator 8 enable the concentrated sulfuric acid and wet chlorine to be in full contact, greatly improving the drying effect of the wet chlorine. Compared with the existing drying technology, this device can more effectively remove moisture and other impurities in wet chlorine, thereby significantly reducing the impurity gas content in chlorine, providing high-quality chlorine for downstream chlorine-using enterprises, ensuring their product quality, and reducing product quality problems and production losses caused by chlorine impurities.

[0056] Furthermore, the drying tower 3 has a concentrated sulfuric acid outlet 303 and a wet chlorine outlet 304, the concentrated sulfuric acid outlet 303 is located at the bottom of the drying tower 3, the concentrated sulfuric acid inlet 302 is located at the top of the drying tower 3, the wet chlorine inlet 301 is located at the bottom of the drying tower 3 and above the concentrated sulfuric acid outlet 303, and the wet chlorine outlet 304 is located at the top of the drying tower 3.

[0057] In the above scheme, concentrated sulfuric acid outlet 303 is located at the bottom of drying tower 3, and it is necessary to control the outflow path and flow control of concentrated sulfuric acid after fully contacting with wet chlorine. The concentrated sulfuric acid outlet 303 position can ensure that concentrated sulfuric acid can naturally and smoothly flow out of drying tower 3 under the action of gravity after completing the drying effect on wet chlorine, avoiding the residual and accumulation of concentrated sulfuric acid in the tower. Concentrated sulfuric acid inlet 302 is located at the top of drying tower 3, and this top feeding mode is combined with the concentrated sulfuric acid outlet 303 of bottom discharging, so that concentrated sulfuric acid forms a flow path from top to bottom in drying tower 3. Wet chlorine inlet 301 is located at the bottom of drying tower 3 and above concentrated sulfuric acid outlet 303, and this positional relationship enables wet chlorine to enter from the bottom and fully contact with the concentrated sulfuric acid flowing from top to bottom in the process of upward flow. Wet chlorine outlet 304 is located at the top of drying tower 3, for the wet chlorine after drying treatment provides a suitable discharge channel. The wet chlorine outlet 304 can ensure that the dried wet chlorine is discharged smoothly while avoiding mixing with the incoming wet chlorine.

[0058] Working process: After the wet chlorine enters from the wet chlorine inlet 301 at the bottom of the drying tower 3, the wet chlorine begins to flow upward under the vibration of the vibrating member 8 and the dispersion of the filler 5. At the same time, the concentrated sulfuric acid entering from the top flows downward under the action of gravity. Since the flow directions of the two are opposite and they are disturbed and dispersed by the filler 5 in the packing layer 4, the contact between them becomes more sufficient and lasting. Impurities such as moisture in the wet chlorine will react strongly with the concentrated sulfuric acid and be absorbed by the concentrated sulfuric acid. After sufficient contact and reaction, the dried wet chlorine is discharged from the wet chlorine outlet 304 at the top, and the concentrated sulfuric acid that absorbs impurities flows out from the concentrated sulfuric acid outlet 303 at the bottom. In the whole process, the filler 5 in the drying tower 3 continuously disperses and mixes the concentrated sulfuric acid and the wet chlorine, ensuring sufficient contact and reaction between the two.

[0059] Furthermore, the drying tower 3 includes: a cylinder 31, a packing layer 4 is located in the cylinder 31; a placement plate 9, which is slidably arranged in the cylinder 31 along the axial direction of the cylinder 31, the placement plate 9 is located at the bottom of the packing layer 4, there are a plurality of fillers 5, and the plurality of fillers 5 are stacked on the placement plate 9, and a vibrating member 8 is in contact with the bottom surface of the placement plate 9. After the vibrating member 8 is actuated, it drives the placement plate 9 to reciprocate along the axial direction of the cylinder 31.

[0060] In the above scheme, the drying tower 3 is composed of a cylinder 31 and a placement plate 9. The cylinder 31 serves as the main structure of the drying tower 3 and provides stable support and accommodation space for the internal packing layer 4 and other components. The cylinder 31 can ensure that it remains stable under internal pressure and external vibration. The packing layer 4 is located in the cylinder 31 and is the area for mixing and drying concentrated sulfuric acid and wet chlorine. The placement plate 9 can flexibly reciprocate along the axial direction of the cylinder 31 under the action of the vibrator 8. There are several fillers 5, which are neatly stacked on the placement plate 9. The vibrator 8 abuts against the bottom surface of the placement plate 9. This tight connection ensures that the vibration of the vibrator 8 can be effectively transmitted to the placement plate 9.

[0061] When wet chlorine enters the drying tower 3 from the wet chlorine inlet 301, the vibrating member 8 will be triggered to start moving. The vibration of the vibrating member 8 will be directly transmitted to the placement plate 9 that is closely abutted therewith, causing the placement plate 9 to start reciprocating movement in the axial direction of the cylinder 31. This reciprocating movement of the placement plate 9 will drive the filler 5 placed thereon to move together. Since the filler 5 is loosely stacked on the placement plate 9, the movement of the placement plate 9 will cause relative movement and vibration between the fillers 5. This vibration will form complex disturbances in the packing layer 4, causing the filler 5 to rearrange under the action of vibration, and the concentrated sulfuric acid will form a complex flow path in the gap and surface of the filler 5, fully interweaving with the wet chlorine, thereby more effectively absorbing moisture and other impurities in the wet chlorine. During the whole process, the reciprocating movement of the placement plate 9 and the vibration of the filler 5 continue, ensuring the full mixing and contact of the concentrated sulfuric acid and the wet chlorine.

[0062] Furthermore, the filler 5 includes: a ring body 501, on which a plurality of through grooves 502 are arranged at intervals on the circumferential side wall; a bending plate 503, one end of which is arranged in the through groove 502 and the other end of which extends into the ring body 501, the bending plate 503 is inclined in the direction of the ring body 501, and the bending plate 503 is used to disperse concentrated sulfuric acid and wet chlorine gas; a baffle 504, which is arranged on the bending plate 503, and a through hole 505 is provided between the baffle and the bending part of the bending plate 503, and the baffle and the through hole 505 are used to increase the flow path of concentrated sulfuric acid and wet chlorine gas.

[0063] In the above scheme, the filler 5 is mainly composed of three parts: a ring body 501, a bending plate 503 and a baffle 504, which work together to achieve efficient dispersion and mixing of concentrated sulfuric acid and wet chlorine. The ring body 501 serves as the basic structure of the filler 5, and a plurality of through holes 505 are arranged at intervals on its circumferential side wall. The through groove 502 and the through hole 505 provide a circulation channel for the flow of concentrated sulfuric acid and wet chlorine. One end of the bending plate 503 is arranged in the through groove 502, and the other end extends into the ring body 501, and the bending plate 503 is inclined with respect to the direction of the ring body 501. The inclined arrangement is to change the flow direction of concentrated sulfuric acid and wet chlorine, so that concentrated sulfuric acid and wet chlorine can turn under the guidance of the bending plate 503 after passing through the through groove 502 of the ring body 501. The bending plate 503 is like a small guide plate, which disperses the fluid that originally flows in a straight line to different directions, increasing the flow path and complexity of the fluid in the filler 5. The baffle 504 is arranged on the bending plate 503, and a through hole 505 is provided between the baffle and the bending part of the bending plate 503. The arrangement of these baffles 504 and the through hole 505 further increases the complexity of the flow path of the concentrated sulfuric acid and the wet chlorine gas. When the fluid passes through the bending plate 503, the baffle 504 will have a blocking and diverting effect on it, so that the fluid changes its flow direction and speed again when passing through the through hole 505 between the baffle and the bending plate 503. This multi-level diversion and diversion design allows the concentrated sulfuric acid and the wet chlorine gas to undergo multiple changes in direction and speed in the filler 5, greatly increasing the contact opportunities and contact areas between them.

[0064] Working process: When concentrated sulfuric acid and wet chlorine flow in the drying tower 3 and pass through the filler 5, they will enter the interior of the filler 5 through the through groove 502 of the ring body 501. Under the action of the bending plate 503, the flow direction of the fluid changes and begins to disperse at different angles in the ring body 501. As the fluid continues to flow, the baffle 504 further blocks and diverts it, causing the fluid to change its path again when passing through the through hole 505 between the baffle and the bending plate 503. In this process, concentrated sulfuric acid and wet chlorine are fully intertwined, collided and mixed in the complex structure of the filler 5. Concentrated sulfuric acid can more comprehensively wrap the wet chlorine, fully contact and react with the water and other impurities therein, thereby more effectively removing impurities in the wet chlorine. Throughout the process, the structure of the filler 5 continuously disperses and mixes the concentrated sulfuric acid and wet chlorine, ensuring full contact and reaction between the two.

[0065] Furthermore, the placement plate 9 has a plurality of filter slots 901, which are used to pass concentrated sulfuric acid and wet chlorine gas. The vibrating member 8 includes: a fixed plate 83, which is arranged on the cylinder 31; a telescopic rod 81, which is slidably penetrated and arranged on the fixed plate 83; a connecting member 87, one end of which is hinged on the telescopic rod 81, and the other end of which is hinged on the cylinder 31; a cam 84, which is rotatably arranged on the bottom surface of the fixed plate 83, and the bottom end of the telescopic rod 81 is hinged on the circumference of the outer wall of the cam 84, and the cam 84 is used to drive the telescopic rod 81 to move back and forth; a top column 86, which is arranged on the top of the telescopic rod 81, and the end of the top column 86 away from the telescopic rod 81 abuts against the bottom surface of the placement plate 9.

[0066] In the above scheme, the filter tank 901 is distributed on the placement plate 9, and its size, shape and position are determined according to the flow rate, flow velocity and flow path of concentrated sulfuric acid and wet chlorine in the drying tower 3. The existence of the filter tank 901 provides a channel for the flow of concentrated sulfuric acid and wet chlorine in the packing layer 4, ensuring that they can pass smoothly up and down on the placement plate 9. The vibrating member 8 includes a fixed plate 83, a telescopic rod 81, a connecting member 87, a cam 84 and a top column 86. The fixed plate 83 is arranged on the cylinder 31, providing a stable installation foundation for the entire vibrating member 8 to ensure that the vibrating member 8 will not loosen or shift during operation. The telescopic rod 81 is slidably arranged on the fixed plate 83, so that the telescopic rod 81 can move up and down flexibly on the fixed plate 83. One end of the connecting piece 87 is hinged on the telescopic rod 81, and the other end is hinged on the barrel 31, which plays the role of connecting the telescopic rod 81 and the barrel 31. The cam 84 is rotatably arranged on the bottom surface of the fixing plate 83, and the bottom end of the telescopic rod 81 is hinged on the circumference of the outer wall of the cam 84. As one of the power sources of vibration, when the cam 84 rotates, it will drive the telescopic rod 81 to reciprocate on the fixing plate 83 through the hinge relationship with the telescopic rod 81. The top column 86 is arranged on the top of the telescopic rod 81, and one end of the top column 86 away from the telescopic rod 81 abuts against the bottom surface of the placement plate 9. When the telescopic rod 81 moves up and down under the drive of the cam 84, the top column 86 will transmit this movement to the placement plate 9, causing the placement plate 9 to vibrate.

[0067] Working process: When wet chlorine enters the drying tower 3 from the wet chlorine inlet 301, the vibration member 8 will be triggered to start. First, the cam 84 starts to rotate. Due to the hinged relationship between the cam 84 and the telescopic rod 81, the rotation of the cam 84 will be converted into the reciprocating movement of the telescopic rod 81 on the fixed plate 83. During the movement of the telescopic rod 81, the connecting member 87 will make corresponding angle adjustments according to its movement direction and strength to ensure the stability of the entire vibration process. As the telescopic rod 81 moves up and down, the top column 86 will transmit this movement to the placement plate 9. Under the push of the top column 86, the placement plate 9 vibrates along the axis direction of the cylinder 31. At the same time, the filter tank 901 on the placement plate 9 allows concentrated sulfuric acid and wet chlorine to pass smoothly, and the flow of the fluid will not be hindered by the vibration of the placement plate 9. Under the action of the vibration of the placement plate 9, the filler 5 placed thereon will also vibrate, thereby enhancing the mixing effect of concentrated sulfuric acid and wet chlorine in the packing layer 4. In the whole process, the action of the vibration member 8 continues, ensuring the full mixing and contact of concentrated sulfuric acid and wet chlorine.

[0068] Furthermore, the cylinder 31 further includes: an extension bar 7 , one end of which is disposed on the inner wall of the cylinder 31 , and the other end of which extends into the cylinder 31 , and the fixing sheet 83 is disposed on the extension bar 7 .

[0069] In the above solution, the extension strip 7 provides a stable installation position for the fixing plate 83, ensuring its stability during vibration, so that the vibration is accurately transmitted to the placement plate 9. This improves the installation stability of the vibrating member 8, reduces shaking, ensures that the vibration effectively acts on the placement plate 9, ensures drying, and reduces chlorine impurities.

[0070] Furthermore, the connecting member 87 includes: a sleeve 871, one end of which is hinged to the inner wall of the cylinder 31; a piston rod 872, one end of which is hinged to the telescopic rod 81, and the other end is slidably arranged in the sleeve 871; a first spring 873, which is sleeved on the piston rod 872, the first spring 873 is located in the sleeve 871, and the first spring 873 provides a force for resetting the piston rod 872.

[0071] In the above scheme, when the vibrating member 8 moves, the telescopic rod 81 makes the piston rod 872 slide in the sleeve 871, the first spring 873 is compressed or stretched, and when the force of the cam 84 changes, the first spring 873 resets the piston rod 872 to make the movement smoother. This makes the vibration process smoother, reduces the impact damage, ensures the vibration is stable and continuous, improves the mixing effect, and reduces the chlorine impurities.

[0072] Furthermore, the power unit 85 is an impeller, which is arranged on the axle of the cam 84, and also includes: an air intake distribution pipe 6, which is arranged in the cylinder 31, the air intake distribution pipe 6 is connected to the wet chlorine gas inlet 301, and the air intake distribution pipe 6 has a plurality of air outlets 601. The power unit 85 is arranged directly above the air outlet 601, and the air outlet 601 discharges the wet chlorine gas to drive the impeller to rotate.

[0073] In the above scheme, the impeller is arranged on the axle of the cam 84, and there is a close mechanical connection between the impeller and the cam 84. The air inlet distribution pipe 6 is arranged in the cylinder 31, and is connected to the wet chlorine inlet 301, and is an important distribution channel after the wet chlorine enters the drying tower 3. The air inlet distribution pipe 6 has a plurality of air outlets 601, and these air outlets 601 are evenly distributed on the air inlet distribution pipe 6.
