Description

Technical Field

[0001] This invention belongs to the technical field of water washing tower equipment, specifically a water washing tower for organic fluorine chemical production with sludge removal function. Background Technology

[0002] In the production process of organofluorine chemicals, in order to effectively remove impurities from the generated gas and products, a water washing tower is often used to wash the generated mixed gas. During operation, the water washing tower filters the gaseous products through the liquid phase component on the tower plate, absorbing and filtering the impurities in the gaseous products. With the reverse flow between the liquid phase and the gaseous products, the impurities flow with the liquid phase component to the bottom of the tower. Under the action of the reboiler set in the bottom of the tower, the liquid phase evaporates. The evaporated gas flows upward and, under the action of the condenser at the top of the tower, is reliquefied and flows back into the tower plate, repeating the washing of the gaseous products.

[0003] During the operation of the water washing tower, impurities eventually accumulate in the liquid phase component in the bottom section of the tower. As the water washing tower continues to operate, the impurity content in the liquid phase component in the bottom section gradually increases. Solid impurities are deposited at the bottom of the bottom section, while impurities dissolved in the liquid phase component also gradually deposit at the bottom of the bottom section as their concentration increases. The deposition of impurities not only hinders the heat conduction of the reboiler, affecting the circulation of the liquid phase component in the water washing tower, but also causes corrosion to the water washing tower due to the long-term deposition of impurities, thus reducing the service life of the water washing tower.

[0004] In existing technologies, to reduce the impact of impurity deposition, liquid level control and periodic replacement are generally used for impurity removal. Specifically, during long-term use, the liquid level of the liquid phase component in the bottom of the column is controlled, thereby controlling the proportion of impurities in the liquid phase. During use, the liquid phase component in the bottom of the column is periodically replaced to remove impurities deposited at the bottom of the column. However, during operation, it is necessary not only to adjust the impurity output and the liquid level of the liquid phase component, but also to strictly control the concentration of impurities in the liquid phase component to prevent large-scale deposition of impurities. At the same time, during periodic replacement, since some impurities are deposited on the inner wall of the water washing tower, it is not easy to completely replace the impurities. Therefore, in actual use, the sludge removal effect is not ideal.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the present invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0006] In view of this, the present invention proposes a water washing tower for organic fluorine chemical production with sludge removal function to solve the above-mentioned technical problems. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this invention proposes a water washing tower for organic fluorine chemical production with sludge removal function.

[0008] The technical solution adopted by this invention to solve its technical problem is as follows: This invention uses a collection component and a displacement component. The collection component collects the impurity-containing liquid phase components and aggregates the impurities contained therein, thereby effectively enhancing the aggregation effect of impurities in the water washing tower. Then, the displacement component replaces the liquid phase components with high impurity concentrations aggregated in the sedimentation dish, thereby enhancing the removal effect and efficiency of impurities. This effectively enhances the control effect of impurities accumulated in the water washing tower, avoiding long-term accumulation of impurities in the water washing tower and thus preventing damage to the water washing tower components.

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] like Figures 1 to 5As shown, the organic fluorine chemical production water washing tower with sludge removal function described in this invention includes...

[0041] Tower body 1, which is a hollow structure, with an air inlet pipe 11 fixedly connected to the middle part of the tower body 1 and an air outlet pipe 12 fixedly installed at the top of the tower body 1;

[0042] The tray 13 is a plate-shaped structure with uniformly distributed through holes on its surface;

[0043] Reboiler 14 and condenser 15, wherein the reboiler 14 is installed at the bottom of the tower body 1, the reboiler 14 is used to heat the liquid, and the condenser 15 is used to condense the gas.

[0044] It also includes a collection component, which is installed inside the tower body 1. The collection component is used to collect the impurities from the washing process. The collection component includes...

[0045] Flow guide plate 2, which is fixedly installed on the tower body 1;

[0046] A sedimentation dish 21 is fixedly installed inside the tower body 1. The sedimentation dish 21 is located below the guide plate 2. The guide plate 2 guides the liquid into the inner cavity of the sedimentation dish 21. The reboiler 14 is installed at the bottom of the sedimentation dish 21 and is in communication with the sedimentation dish 21.

[0047] An interception net 22 is fixedly connected to a sedimentation dish 21 and is used to filter impurities in the liquid.

[0048] A displacement component is installed between the guide plate 2 and the converging component. The displacement component and the converging component work together to continuously displace the liquid phase components in the deposition dish 21.

[0049] In the production and preparation of organofluorine chemical products, the purification and impurity removal of gaseous products are carried out using a water washing tower. During the purification and impurity removal process, the gas mixture is introduced into the tower body 1 through the inlet pipe 11. The introduced gas moves upward along the tower body 1 and, upon contact with the tray 13, the impurities in the gas mixture are fixed and intercepted by the liquid phase component on the tray 13, thereby purifying the gaseous product. As the reboiler 14 at the bottom of the tower body 1 and the condenser 15 at the top of the tower body 1 continue to operate, the liquid phase component vaporizes from the bottom of the tower body 1 and rises to the top of the tower, then condenses at the top and falls downward. During the downward fall, the liquid phase component lands on the tray 13, increasing the amount of liquid phase component on the tray 13. The increased liquid phase component flows downward along the tray 13 and the tower body 1, eventually flowing back to the bottom of the tower body 1. During this process, the impurities fixed and intercepted by the liquid phase component flow with the liquid phase component to the bottom of the tower body 1, causing the impurities to accumulate at the bottom of the tower body 1.

[0050] As the liquid phase component flows towards the bottom of the tower body 1, it gradually comes into contact with the guide plate 2 and is guided by it, causing the liquid phase component containing impurities to flow in a specific direction. This directional flow eventually flows into the sedimentation dish 21, where the liquid phase component settles, causing solid dust and other impurities to settle downwards and accumulate at the bottom. Simultaneously, the liquid phase component at the top is filtered by the interception net 22 and flows into the reboiler 14. After being heated and evaporated in the reboiler 14, the generated gas mist floats upwards, while the remaining liquid phase component re-enters the sedimentation dish 21 and converges there, causing the concentration of soluble impurities to gradually increase. This leads to the gradual condensation and deposition of the soluble impurities at the bottom of the sedimentation dish 21.

[0051] As the impurity content in sedimentation dish 21 gradually increases, the displacement component is activated. The displacement component extracts the liquid phase component with a higher impurity content from sedimentation dish 21 and introduces pure liquid phase components from the outside environment into sedimentation dish 21, thereby replacing the liquid phase component. During the displacement process, impurities flow to the outside environment along with the liquid phase component, and after filtration, removal, and purification, the liquid phase can be reused.

[0052] This application incorporates a collection component and a displacement component in a water washing tower. The collection component collects the impurity-containing liquid phase components and aggregates the impurities contained therein, thereby effectively enhancing the aggregation effect of impurities in the water washing tower. Then, the displacement component replaces the liquid phase components with high impurity concentrations aggregated in the sedimentation dish 21, thereby enhancing the removal effect and efficiency of impurities. This effectively enhances the control effect of impurities accumulated in the water washing tower, preventing impurities from accumulating in the water washing tower for a long time and causing damage to the water washing tower components.

[0053] In a preferred embodiment of the present invention, a rotating shaft 23 is rotatably connected inside the sedimentation dish 21, and uniformly distributed stirring blades 24 are fixedly connected to the rotating shaft 23.

[0054] By incorporating stirring blades 24 and a rotating shaft 23, during the aggregation of liquid phase components, the rotation of the shaft 23 causes the stirring blades 24 to rotate within the sedimentation dish 21, thereby propelling the liquid phase components and causing them to rotate. Due to the shape of the sedimentation dish 21 and the continuous rotation of the liquid phase components, vortices are formed within the dish. Under the combined action of centrifugal force and gravity, larger solid dust impurities converge towards the bottom of these vortices. As more liquid phase components are added, the height of the vortices gradually increases, causing excess liquid phase components to flow out of the sedimentation dish 21 and eventually into the reboiler 14. After heating and evaporation in the reboiler 14, the liquid phase components return to the sedimentation dish 21.

[0055] Stirring the liquid phase component causes solid impurities in the liquid phase component to settle and aggregate, thereby enhancing the aggregation effect of impurities. At the same time, since the liquid phase component is in a continuous rotating state, the impurities in the liquid phase component, after being deposited into the deposition dish 21, will also be pushed away from the inner wall of the deposition dish 21 by the rotating liquid phase component, thereby reducing the probability of impurities adhering to and solidifying on the deposition dish 21. In conjunction with the displacement component, the effect of removing impurities is enhanced.

[0056] In a preferred embodiment of the present invention, a ring plate 25 is fixedly connected to the side wall of the sedimentation dish 21. The ring plate 25 is inclined, and the height of the side of the ring plate 25 near the side wall of the tower body 1 is less than the height of the side of the ring plate 25 near the sedimentation dish 21.

[0057] By setting the annular plate 25 and installing it on the outer wall of the sedimentation dish 21, and with the annular plate 25 in an inclined state, when the liquid phase component rotates in the sedimentation dish 21, the excess liquid phase component flows to the outside of the sedimentation dish 21 under the action of rotation, and is guided and directed by the annular plate 25 to collect the liquid phase component, thereby facilitating the liquid phase component to flow into the reboiler 14. This allows the liquid phase component to circulate in a timely manner, enhances the replacement effect of the liquid phase component on the tray 13, and accelerates the efficiency of impurities collecting in the sedimentation dish 21.

[0058] In a preferred embodiment of the present invention, a drive box 3 is fixedly connected below the guide plate 2, the rotating shaft 23 extends into the drive box 3, and an impeller 31 is fixedly connected to the rotating shaft 23 inside the drive box 3. The side wall of the drive box 3 is provided with evenly distributed ventilation holes 32. The rotating shaft 23 is hollow and the inner cavity of the rotating shaft 23 is designed to communicate with the drive box 3.

[0059] In actual operation, the steam generated in the reboiler 14 is discharged upwards towards the sedimentation dish 21. Due to the cooperation between the guide plate 2 and the drive box 3, the upward flow channel of the gas is blocked, resulting in a slower upward flow efficiency. At this time, the efficiency of steam formation in the reboiler 14 is greater than the efficiency of steam discharge, which increases the air pressure between the guide plate and the bottom of the tower body 1. The increased air pressure causes the airflow to flow into the vent 32 on the drive box 3 and finally flow upwards towards the guide plate 2 through the inner cavity of the rotating shaft 23. During the steam flow, since the direction of the vent 32 on the drive box 3 is in harmony with the blades of the impeller 31, the airflow into the drive box 3 generates a driving force on the impeller 31, causing the impeller 31 to rotate within the drive box 3. This, in turn, causes the rotating shaft 23 to rotate, thus stirring the liquid phase components in the sedimentation dish 21.

[0060] By evaporating the liquid phase components using the reboiler 14, the impeller 31 is driven by the airflow under the action of steam energy. The impeller 31 drives the rotating shaft 23, which in turn drives the stirring blades 24, ultimately causing the liquid phase components to rotate. This enhances the aggregation effect on impurities. In this process, the kinetic energy of the steam itself is used as the power source for the rotation of the liquid phase components. Therefore, during the washing of gaseous products, the aggregation components can operate continuously, effectively enhancing the aggregation and removal of impurities. At the same time, the use of steam energy can also effectively enhance the energy utilization rate in the water washing tower and reduce energy consumption.

[0061] In a preferred embodiment of the present invention, a baffle 4 is fixedly connected inside the drive box 3, the baffle 4 isolates the inner cavity of the drive box 3 from top to bottom, an impeller 31 is installed on both sides of the rotating shaft 23, the drive box 3 is sealed to the guide plate 2, a liquid flow hole 41 is opened on the top of the drive box 3, and a uniformly distributed liquid outlet pipe 42 is fixedly connected to the side wall of the drive box 3.

[0062] In actual use, by sealing the drive box 3 with the guide plate 2, the steam can only flow into the vent 32, effectively enhancing the driving effect of the steam on the impeller 31. At the same time, the liquid phase components gathered at the top of the guide plate 2 also flow into the drive box 3 through the liquid flow hole 41, and after being isolated by the baffle 4, they are discharged to the outside through the liquid outlet pipe 42. During the flow of the liquid phase components, they also generate a driving force on the impeller 31. By utilizing the same rotation of the upper and lower impellers 31, the rotation speed of the impeller 31 and the rotating shaft 23 is enhanced, thereby enhancing the driving effect on the liquid phase components in the sedimentation dish 21, increasing the flow rate of the vortex, and thus improving the impurity aggregation efficiency.

[0063] In a preferred embodiment of the present invention, the replacement component includes

[0064] The displacement cavity 5 is fixedly connected to the bottom of the tower body 1, and the rotating shaft 23 extends into the interior of the displacement cavity 5;

[0065] The piston plate 51 and the rotating shaft 23 are located in the displacement cavity 5 and have reciprocating threads. The piston plate 51 is helically driven by the reciprocating threads.

[0066] Extraction tube 52 and discharge tube 53 are fixedly connected to both ends of the replacement chamber 5. The extraction tube 52 and discharge tube 53 are used to connect the replacement chamber 5 with the sedimentation dish 21 and the external pipeline. Both the extraction tube 52 and discharge tube 53 are unidirectional tubes.

[0067] During the rotation of the rotating shaft 23 due to the impact of airflow and liquid flow, the portion of the rotating shaft 23 located within the displacement chamber 5 rotates. Because a reciprocating thread is provided at one end of the rotating shaft 23 within the displacement chamber 5, and a piston plate 51 is connected via a helical drive, and the piston plate 51 is limited by the inner wall of the displacement chamber 5, it reciprocates up and down within the displacement chamber 5. During this up-and-down movement of the piston plate 51, through the cooperation of the extraction pipe 52 and the discharge pipe 53, the upper and lower chambers of the displacement chamber 5, separated by the piston plate 51, continuously discharge the impurity-laden liquid phase components from the deposition dish 21 to the outside, while pure liquid phase components from the outside flow into the upper end of the deposition dish 21. This displaces the liquid phase components in the deposition dish 21, thereby enhancing the removal of impurities.

[0068] Meanwhile, since the rotating shaft 23 continues to rotate during the gas washing and purification process, the replacement process continues. By adjusting the size of the replacement chamber 5, the impurity-containing liquid phase components at the bottom of the sedimentation dish 21 can be slowly extracted continuously, thereby improving the control effect of impurity content in the water washing tower and reducing the probability of impurities depositing and adhering to the sedimentation dish 21 and the inner wall of the water washing tower.

[0069] In a preferred embodiment of the present invention, a heat exchange tube 6 is fixedly connected to the piston plate 51, and the heat exchange tube 6 is used to enhance the heat exchange effect on both sides of the displacement cavity 5.

[0070] By setting up heat exchange tube 6, during the replacement of liquid phase components, the contact area between the liquid phase components at the upper and lower ends of the replacement chamber 5 is increased, thereby enhancing the heat exchange effect between the newly added liquid phase components and the liquid phase components to be discharged, thereby reducing the outflow of heat inside the water washing tower, and thus enhancing the evaporation efficiency of the reboiler 14.

[0071] In a preferred embodiment of the present invention, the heat exchange tube 6 is made of an elastic hose, and the elastic hose is arranged in a spiral shape.

[0072] By setting the heat exchange tube 6 in a spiral shape and making it from an elastic material, it can not only effectively increase the heat exchange effect between liquid phase components in actual use, but also utilize the properties of the elastic flexible tube to enable the heat exchange tube 6 to deform, thereby reducing the obstruction to the up and down movement of the piston plate 51.

[0073] In a preferred embodiment of the present invention, a baffle 7 is fixedly connected to the rotating shaft 23. The baffle 7 is located in the sedimentation dish 21. The baffle 7 has a partially annular design and is used to block the extraction tube 52 in the sedimentation dish 21.

[0074] By setting baffle 7, and utilizing the fact that baffle 7 is not completely annular, as baffle 7 rotates with rotating shaft 23, the opening of extraction tube 52 connected to sedimentation dish 21 is located on the rotation path of baffle 7. Therefore, during the rotation of baffle 7, extraction tube 52 is blocked and intermittently opened, thus giving impurities in sedimentation dish 21 time to accumulate and enhancing the extraction effect of impurities.
