Description

Technical Field

[0001] The invention relates to the technical field of paraffin production, in particular to a residual chlorine treatment device for chlorinated paraffin. Background Art

[0002] During the production process of chlorinated paraffin, residual chlorine and hydrogen chloride gas will remain inside the chlorinated paraffin. Chlorine is a toxic gas that can invade the human body through the respiratory tract and dissolve in the moisture contained in the mucous membrane to generate hypochlorous acid and hydrochloric acid, causing damage to the upper respiratory tract mucosa. The residual chlorine remaining in the chlorinated paraffin is seriously harmful to the environment and can cause pollution to water bodies. Therefore, when making chlorinated paraffin, the residual chlorine inside needs to be removed.

[0003] To solve this problem, a Chinese patent document with publication number CN118976766A discloses a residual chlorine treatment device for chlorinated paraffin, including a storage tank, a container tank, a negative pressure box, a drive motor, a rotating shaft, a stirring rod, and a vacuum pump. The storage tank is connected to the container tank through a delivery pipe. The drive motor is connected to the rotating shaft in a driving manner. The liquid in the storage tank is transported to a container tank with a smaller volume than the storage tank, a vacuum operation is performed in the container tank, and the liquid is disturbed by stirring and aerating, so that the residual chlorine is removed more thoroughly.

[0004] However, the following problems exist when using the above-mentioned device: the turbulence formed by mechanical stirring and gas blowing can accelerate the mass transfer reaction between free chlorine and the neutralizer, and promote the escape of volatile substances such as chlorine. However, the violent gas-liquid mixing will cause micron-sized bubble groups to form in the system. These bubbles will absorb chlorinated paraffin sol particles during the rising process, forming aerosols and escaping with the airflow, resulting in product loss. In addition, the aerosols will gradually deposit in pipe elbows, valves and other parts during the flow process, forming viscous polymer blockages, causing equipment blockage and affecting operational safety. For this reason, we propose a residual chlorine treatment device for chlorinated paraffin. Summary of the Invention

[0016] The present invention has at least the following beneficial effects:

At the same time, the cleaning part and the scraping part are linked to remove the condensed chlorinated paraffin in the filter holes, effectively preventing the filter plate from clogging and ensuring the continuous and stable operation of the entire production process.

[0018] 2. Compared with the ordinary U-shaped condensation plate, the condensation filter plate has obvious advantages. By increasing the surface area, the condensation filter screen can achieve the rapid condensation of gaseous residual chlorine and the physical interception of tiny droplets at the same time; while the U-shaped condensation channel mainly relies on gravity sedimentation and temperature difference condensation, and has a low interception efficiency for smaller droplets. In addition, the filter screen structure can effectively break the vortices in the air flow and reduce the possibility of the condensed droplets being re-entrained by the gas; in contrast, the longer flow path of the U-shaped tube may cause the re-evaporation of the condensed droplets due to too high local flow velocity.

[0019] 3. The setting of the discharge part can melt the condensed chlorinated paraffin and re-discharge it into the chlorinated paraffin solution. After melting, the fluidity of the liquid chlorinated paraffin is significantly enhanced. Compared with the direct discharge of solid condensate, the risk of pipeline blockage can be greatly reduced. Moreover, the melted chlorinated paraffin can be fully mixed with the main solution, effectively eliminating local crystallization or phase separation caused by condensation, ensuring the consistency of product viscosity and density, and improving product quality.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1: Please refer to Figure 1-11 , the present invention provides a technical solution: A residual chlorine treatment device for chlorinated paraffin includes a vacuum tank 1 and an isolation plate 2 arranged in the vacuum tank 1, and a heat insulation coating is applied on the surface of the isolation plate 2 facing the chlorinated paraffin in the vacuum tank 1. A filtration chamber 3 is arranged on the isolation plate 2, and air inlet holes 31 communicating with the vacuum tank 1 are opened on the filtration chamber 3 and the isolation plate 2. A condensation filter plate 4 is arranged in the filtration chamber 3. A separation unit 5 connected to the condensation filter plate 4 is arranged in the filtration chamber 3. The separation unit 5 is used to drive the condensation filter plate 4 to separate the residual chlorine gas flowing through, and at the same time scrape the chlorinated paraffin generated by condensation on the condensation filter plate 4. A flow disturbing unit 10 is arranged on the isolation plate 2 to inject gas into the chlorinated paraffin solution in the vacuum tank 1.

[0035] The separation unit 5 includes a condensation member 6 disposed in the filtration chamber 3 for condensing the residual chlorine gas flowing through the condensation filter plate 4. A cleaning member 7 is disposed in the filtration chamber 3 for cleaning the filter holes on the condensation filter plate 4. A scraping member 8 is disposed in the filtration chamber 3 for scraping the condensate cleaned by the cleaning member 7. A discharging member 9 is disposed in the filtration chamber 3 for discharging the scraped condensate back into the vacuum tank 1.

[0036] The condensation member 6 includes diversion tubes 61 disposed on both sides of the condensation filter plate 4. A circulation tube 62 is disposed on the diversion tube 61. A low-temperature circulation device 63 connected to the circulation tube 62 is disposed on the partition plate 2. A purification tube 64 is disposed on the filtration chamber 3. The purification tube 64 penetrates through the side wall of the vacuum tank 1, and the purification tube 64 is externally connected to a chlorine purification device. When the low-temperature circulation device 63 operates, the cooling medium enters each diversion tube 61 through the circulation tube 62, and then enters the condensation filter plate 4 through the diversion tube 61. Since there are multiple diversion tubes 61 and they are evenly arranged on both sides of the condensation filter plate 4, the cooling medium will enter the condensation plate more evenly. The uniform entry of the cooling medium into the condensation filter plate 4 enables each part of the condensation filter plate 4 to fully play the condensation role, avoiding the situation of insufficient or excessive local condensation, greatly improving the stability and uniformity of the condensation effect of each part of the condensation plate, thereby enhancing the condensation efficiency of the chlorinated paraffin sol during the entire condensation process, ensuring that more chlorinated paraffin sol is effectively condensed and recovered, improving the resource recovery rate. At the same time, the uniform air flow distribution reduces the problem of local stress concentration caused by uneven air flow, reduces the risk of damage to the condensation filter plate 4 and related components due to uneven force, extends the service life of the equipment, reduces the cost of equipment maintenance and replacement, and ensures the long-term stable and efficient operation of the equipment.

[0037] The cleaning member 7 includes a driving lead screw 71 rotatably disposed on the filtration chamber 3. A driving motor 74 is disposed outside the filtration chamber 3, and the power output end of the driving motor 74 is connected to the driving lead screw 71. A moving rod 72 is slidably disposed in the filtration chamber 3. One end of the driving lead screw 71 located in the filtration chamber 3 penetrates through the moving rod 72 and is threadedly connected to the moving rod 7, and the moving rod 72 is in contact with the condensation filter plate 4. A circular groove 73 is formed on the moving rod 72, and the notch of the circular groove 73 faces the surface of the condensation filter plate 4. A sliding frame 75 is disposed in the filtration chamber 3 on the side of the condensation filter plate 4 away from the moving rod 72. An electric push rod 76 connected to the sliding frame 75 is disposed in the filtration chamber 3. A plurality of extension rods 77 are disposed on the sliding frame 75, and a cleaning plate 78 is disposed at the end of the extension rod 77. The cleaning plate 78 is slidably connected to the filter holes on the condensation filter plate 4.

[0038] After a period of residual chlorine gas separation, some condensed chlorinated paraffin will be attached to the condensation filter plate 4. At this time, the staff can first start the electric push rod 76. The electric push rod 76 drives the sliding frame 75 to move synchronously, and further drives the multiple extension rods 77 and cleaning plates 78 set on the sliding frame 75 to move. During the movement of the cleaning plate 78, it docks with the filter holes on the condensation filter plate 4 and simultaneously pushes the condensed chlorinated paraffin in the filter holes out of the filter holes. At this time, the filter holes can be cleaned in time and effectively to avoid the continuous accumulation of chlorinated paraffin in the filter holes and cause blockage, ensuring The condensation filter plate 4 always has good air permeability and condensation performance, maintaining its normal condensation and separation function of the chlorinated paraffin sol in the residual chlorine gas, and then drives the drive motor 74 to work, synchronously drives the drive screw 71 to rotate, and the rotation of the drive screw 71 drives the moving rod 72 threadedly connected to it to move. While the moving rod 72 moves, the condensate on the condensation filter plate 4 is scraped into the circular groove 73 in the moving rod 72. Through the automated operation of the electric push rod 76 and the drive motor 74, the automation of the cleaning and scraping process is realized, which greatly reduces the difficulty and labor intensity of manual cleaning.

[0039] The scraper 8 includes a rotating shaft 81 rotatably set in the circular groove 73, and a plurality of fixed plates 82 are set on the rotating shaft 81. The plurality of fixed plates 82 are arranged in a circular array around the rotating shaft 81. A contraction groove 83 is opened on the fixed plate 82, and a scraper 84 is slidably set in the contraction groove 83. A buffer spring 85 is provided on the scraper 84, and one end of the buffer spring 85 is connected to the contraction groove 83. A power shaft 86 is rotatably set at one end of the moving rod 72, and one end of the power shaft 86 passes through the circular groove 73 and is connected to the rotating shaft 81. A power gear 87 is provided at one end of the power shaft 86 located on the outer side of the circular groove 73. The power gear 87 is connected to the power shaft 86 through a one-way bearing, and the side wall of the filter bin 3 is provided with a power rack 88 meshing with the power gear 87.

[0040] When the moving rod 72 descends, it drives the power shaft 86 arranged thereon to move synchronously. When the power shaft 86 moves, it drives the power gear 87 arranged at its end to move synchronously. Because the power gear 87 is engaged with the power rack 88, the power gear 87 will rotate under the push of the power rack 88 during the movement of the power gear 87. The rotation of the power gear 87 drives the power shaft 86 to rotate synchronously. The rotation of the power shaft 86 drives the rotating shaft 81 to rotate. The rotation of the rotating shaft 81 drives the fixed plate 82 arranged thereon and the scraper 84 slidingly arranged on the fixed plate 82 to rotate synchronously. When the scraper 84 rotates with the rotating shaft 81, it elastically adheres to the surface of the condensation filter plate 4 and scrapes the attachments into the circular groove 73. At the same time, the design of the rubber scraper 84 makes the surface of the condensation filter plate 4 cleaned more cleanly.

[0041] This design can deeply clean the surface of the condensation filter plate 4, effectively remove the condensate attached to the filter plate, ensure that the condensation filter plate 4 always remains clean, maintain good condensation performance. At the same time, the scraper 84 made of rubber material has good flexibility and conformability. When it rotates in contact with the side wall of the condensation filter plate 4, it can better conform to the surface of the filter plate, completely scrape off the attachments, make the surface of the condensation filter plate 4 cleaner, reduce problems such as uneven condensation and reduced efficiency caused by residual attachments, and improve the condensation recovery effect of chlorinated paraffin sol in the residual chlorine gas.

[0042] Moreover, timely cleaning of the attachments on the condensation filter plate 4 can prevent the filter plate from being corroded or blocked due to the long-term accumulation of attachments, thereby preventing the performance degradation of the condensation filter plate 4, extending its service life, reducing the equipment maintenance cost and replacement frequency, ensuring the long-term stable operation of the equipment. At the same time, this cleaning process is automated through the linkage of a series of mechanical components, eliminating the need for frequent manual cleaning of the condensation filter plate 4 by workers, reducing the workload and labor intensity of manual operations, and also reducing the errors and safety risks that may be brought by manual operations, improving the convenience and safety of operations.

[0043] The discharge part 9 includes a baffle slot 91 arranged in the circular slot 73. A limiting plate 93 is slidably arranged in the baffle slot 91. A return spring 92 connecting the baffle slot 91 is arranged on the limiting plate 93. A discharge slot 94 is arranged on the circular slot 73. An extrusion slot 95 is opened on the discharge slot 94. A sealing plate 96 is slidably arranged in the extrusion slot 95. An extrusion spring 97 is arranged on the sealing plate 96. One end of the extrusion spring 97 is connected to the extrusion slot 95. A conduction cavity 98 cooperating with the discharge slot 94 is arranged at the bottom of the filter chamber 3. And the surface of the sealing plate 96 in contact with the conduction cavity 98 is a smooth inclined surface. A receiving cavity 99 is opened in the partition plate 2. The receiving cavity 99 is communicated with the conduction cavity 98. And the bottom surface of the receiving cavity 99 is an inclined surface. A discharge pipe 911 is arranged in the receiving cavity 99. The discharge pipe 911 is communicated with the vacuum tank 1. A hot melt cavity 910 is opened in the partition plate 2. The hot melt cavity 910 is communicated with the circulation pipe 62.

[0044] During the continuous downward movement of the moving rod 72, the discharge groove 94 formed on the moving rod 72 is docked with the conduction cavity 98, and under the extrusion of the conduction cavity 98, the sealing plate 96 is pushed to move, causing the sealing plate 96 to retract against the pressure of the extrusion spring 97, so that the circular groove 73 communicates with the conduction cavity 98. Thus, the condensate in the circular groove 73 is sent into the receiving cavity 99 through the conduction cavity 98. Since the receiving cavity 99 is adjacent to the heat melting cavity 910, and the gas after heat exchange flowing through the heat melting cavity 910 will cause the temperature in the heat melting cavity 910 to rise, the condensate falling into the receiving cavity 99 will melt under the drive of heat and be discharged back into the vacuum tank 1 again. After the discharge is completed, controlling the driving motor 74 to rotate reversely can reset the moving rod 72. At the same time, the sealing plate 96 extends out again under the push of the extrusion spring 97 to seal the discharge groove 94. The design of the limiting plate 93 can clean the scraping plate 84 during the rotation process, effectively preventing the condensate from adhering to the scraping plate 84. When the moving rod 72 descends, the discharge groove 94 is docked with the conduction cavity 98, and under the extrusion effect, the sealing plate 96 is pushed to move, realizing the communication between the circular groove 73 and the conduction cavity 98, and automatically sending the condensate in the circular groove 73 into the receiving cavity 99. This process does not require manual intervention, realizing the automation of condensate discharge, improving work efficiency, and reducing the errors and labor intensity that may be brought by manual operation. The design of the limiting plate 93 can clean the scraping plate 84 during the rotation process, effectively preventing the condensate from adhering to the scraping plate 84. This ensures that the scraping plate 84 can always maintain a good working state during the subsequent cleaning process and will not affect the cleaning effect due to the adhesion of condensate, further improving the reliability and stability of the equipment. Finally, the heat melting cavity 910 uses the waste heat introduced through the circulation pipe 62 to melt the condensate and discharge it back into the chlorinated paraffin solution again. After melting, the fluidity of the liquid chlorinated paraffin is significantly enhanced. Compared with the direct discharge of solid condensate, the risk of pipeline blockage can be greatly reduced. Moreover, the melted chlorinated paraffin can be fully mixed with the main solution, effectively eliminating local crystallization or phase separation caused by condensation, ensuring the consistency of the product viscosity and density, and improving the product quality.

[0045] The turbulence unit 10 includes a disturbing member 11 provided on the partition plate 2. The chlorinated paraffin solution is stirred by the disturbing member 11 and gas is simultaneously blown in. A deflecting member 12 is provided on the disturbing member 11, and the stirring angle of the disturbing member 11 is adjusted by using the deflecting member 12.

[0046] The disturbing member 11 includes a power bin 111 provided on the partition plate 2. A power source is provided in the power bin 111. A disturbing pipe 112 connected to the power source is rotatably provided on the power bin 111. An air inlet pipe 113 communicating with the disturbing pipe 112 is provided on the power bin 111. The air inlet pipe 113 is externally connected to a gas source. A plurality of air blowing plates 114 are rotatably provided on the disturbing pipe 112. The air blowing plates 114 are of a hollow structure, and a plurality of air spraying holes 115 are formed on their surfaces.

[0047] The deflecting member 12 includes a mounting groove 121 formed in the fixing plate 82, a torsion spring 122 is arranged on the mounting groove 121, and the torsion spring 122 is connected to the perturbation tube 112.

[0048] During the treatment of residual chlorine gas, by driving the rotation of the perturbation tube 112 to drive the rotation of a plurality of air-blowing plates 114 mounted on the perturbation plate, the chlorinated paraffin liquid is stirred, and air is blown into the chlorinated paraffin liquid during the stirring process. Moreover, the deflection angle of the air-blowing plate 114 can be adaptively adjusted through the elastic deformation of the torsion spring 122 to realize the dynamic control of the stirring intensity. When there is more residual chlorine gas in the chlorinated paraffin in the initial stage and the stirring speed is faster, the angle of the air-blowing plate 114 is changed to make the stirring effect better. And in the later stage of the treatment of residual chlorine gas when the stirring speed is slower, the torsion spring 122 drives the air-blowing plate 114 to deflect, making the stirring amplitude smaller, thereby reducing the probability of the residual chlorine gas entraining the paraffin sol. Driving the rotation of the perturbation tube 112 to drive the air-blowing plate 114 to stir the chlorinated paraffin liquid can make the liquid fully mixed, break the concentration gradient and temperature gradient inside the liquid, and make the properties of each part of the chlorinated paraffin liquid more uniform. This helps to improve the stability and consistency of the subsequent treatment process, ensure the product quality. When there is more residual chlorine gas in the chlorinated paraffin in the initial stage and the stirring speed is faster, the torsion spring 122 changes the angle of the air-blowing plate 114. This design enables the air-blowing plate 114 to better adapt to the working condition of rapid stirring, further enhancing the stirring strength and effect. Through more efficient stirring and air-blowing, the escape speed of the residual chlorine gas from the chlorinated paraffin liquid is increased, the initial treatment efficiency is improved, and the treatment time is shortened. In the later stage of the treatment of residual chlorine gas when the stirring speed is slower, the torsion spring 122 drives the air-blowing plate 114 to deflect, making the stirring amplitude smaller. This change effectively reduces the probability of the residual chlorine gas entraining the paraffin sol, avoids the paraffin sol being re-brought out by the gas due to excessive stirring, and ensures that the recovered paraffin sol will not be lost again, improving the purity and efficiency of resource recovery.

[0049] Example 2: Please refer to Figure 12, the present invention provides a technical solution: A plurality of guide plates 13 are arranged inside the filtration chamber 3 on the side of the condensation filter plate 4 close to the air inlet hole 31, and the plurality of guide plates 13 are cross - arranged to form a U - shaped air passage. The air - contact surface of the guide plate 13 is a smooth inclined plane. The U - shaped air passage formed by the cross - arrangement of the guide plates 13 can guide the gas to flow uniformly towards the condensation filter plate 4, avoiding the situation of local accumulation or poor flow of the gas in the filtration chamber 3. The uniformly distributed air flow enables each part of the condensation filter plate 4 to fully play its role, ensuring the stability and consistency of the condensation process, and improving the working efficiency of the entire filtration chamber 3. The U - shaped air passage formed by the cross - arrangement of the plurality of guide plates 13 prolongs the residence time of the high - heat residual - chlorine gas in the filtration chamber 3. During the flow process, the gas will exchange heat with the low - temperature environment in the filtration chamber 3, thereby achieving preliminary cooling. This preliminary cooling can reduce the temperature of the gas when it enters the condensation filter plate 4 and reduce the direct impact of high temperature on the condensation filter plate 4.
