Description

Technical Field

[0001] The invention relates to the technical field of packed towers, in particular to a packed tower for effectively separating ethyl chloride and hydrogen chloride. Background Art

[0002] Ethyl chloride is primarily used in the synthesis of dye intermediates, fragrance intermediates, ethyl cellulose, antimicrobial agents, and pesticides, and has a wide range of applications. Currently, ethyl chloride is synthesized using the ethanol-hydrochloric acid or ethanol-hydrogen chloride methods, accounting for over 80% of the total market. Packed towers are currently used to separate ethyl chloride and hydrogen chloride to purify ethyl chloride, primarily through physical or chemical absorption.

[0003] Existing technology utilizes the difference in solubility between ethyl chloride and hydrogen chloride in specific solvents (such as water) to achieve selective separation of the two using packed towers. For example, hydrogen chloride is readily soluble in water, while ethyl chloride is less soluble. Therefore, HCl is absorbed by the water, while ethyl chloride is discharged as a gas. A gas mixture containing ethyl chloride and HCl enters the tower from the bottom, while a solvent (such as cold water) is sprayed down from the top, countercurrently contacting the rising gas. HCl is absorbed by the solvent due to its high solubility, while ethyl chloride, due to its poor solubility, continues to rise to the top of the tower and is discharged. An HCl-rich solution (such as hydrochloric acid) flows out from the bottom of the tower, and purified ethyl chloride gas is collected at the top of the tower. The solvent entering from the top of the tower body is first dispersed by the liquid distributor and enters the bulk packing area. The rising gas entering from the bottom of the tower body also enters the bulk packing area, and the two fully react in the bulk packing area. However, since the bulk packing area is usually composed of a number of individual packings with a certain shape, and the structure has no fixed shape, it is inevitable that some solvent cannot flow smoothly through the bulk packing area, and thus accumulates in the bulk packing area, affecting its full reaction with the gas and affecting the separation effect of the packed tower. Summary of the Invention

[0004] Based on this, in order to solve the above technical problems, the present invention adopts the following technical solutions: A packed tower for effectively separating ethyl chloride and hydrogen chloride, comprising: A tower body, wherein a lower inlet is installed at the bottom of the tower body and an upper inlet is installed at the top of the tower body; A liquid distributor is provided in the tower body, comprising a liquid inlet pipe connected to the upper inlet, a distribution box connected to the bottom output end of the liquid inlet pipe, and an overflow trough connected to the bottom of the distribution box. Distribution ports are provided at positions corresponding to the overflow trough, and a weight sensor is installed between the distribution box and the overflow trough. A bulk packing area, the bulk packing area is arranged below the liquid distributor, the bulk packing area includes a bulk packing body and an upper screen and a lower screen respectively arranged at the upper and lower ends of the bulk packing body, a middle vibration plate is installed in the middle of the bulk packing body, a vibration motor is installed at the upper end of the middle vibration plate through a conduction rod, a weight detection mechanism installed on the inner wall of the tower body is provided above the screen, and a detection end of the weight detection mechanism is connected to the screen for detecting weight data of the screen; A separation intelligent controller is provided on one side of the tower body. A separation detection module, a processing module and a separation control module are provided on the separation intelligent controller. The separation detection module is respectively connected to the weight sensor, the weight detection mechanism and the processing module signals. The processing module is connected to the separation control module signals. The separation control module is connected to the vibration motor signals.

[0005] As a preferred embodiment of the packed tower for effectively separating ethyl chloride and hydrogen chloride provided by the present invention, the weight detection mechanism includes a detection cylinder installed on the inner wall of the tower body, a lower elastic piston plate and an upper elastic piston plate vertically slidably connected to the inner wall of the detection cylinder respectively, the bottom of the lower elastic piston plate is connected to the screen plate through a connecting rod, the upper elastic piston plate is placed above the lower elastic piston plate, and a distance sensor installed on the inner wall of the detection cylinder is provided above the upper elastic piston plate. The separation detection module is connected to the distance sensor signal. When the solvent enters the bulk filler body, the overall weight of the screen plate, the bulk filler body and the lower screen plate will increase. At this time, the screen plate drives the connecting rod and the lower elastic piston plate to move downward, and the pressure between the lower elastic piston plate and the upper elastic piston plate is reduced, thereby driving the upper elastic piston plate to move downward synchronously. At this time, the upper elastic piston plate is detected by the distance sensor The displacement distance data of the plug plate is collected and sent to the separation detection module. The processing module can calculate the corresponding solvent value flowing through the bulk filler body through the distance data sent by the distance sensor, thereby judging the solvent value flowing through the bulk filler body, and by setting the lower elastic piston plate, the lower elastic piston plate is an elastic material, which can drive the upper plate to vibrate when the vibration motor is working for preliminary filtering. A buffer solution is filled between the lower elastic piston plate and the upper elastic piston plate. The top and bottom of the bulk filler area are both open settings. The upper elastic piston plate and the lower elastic piston plate are non-contact designs, which also simultaneously reduce the influence of the frequent vibration of the lower elastic piston plate on the up and down movement of the upper elastic piston plate, so that the upper elastic piston plate can better move with the change of the solvent weight on the bulk filler body, reduce the influence of the vibration of the upper plate, and improve the accuracy of judging the solvent weight on the bulk filler body through the detection results of the distance sensor.

[0006] As a preferred embodiment of the packed tower for effectively separating ethyl chloride and hydrogen chloride provided by the present invention, a buffer solution is filled between the lower elastic piston plate and the upper elastic piston plate, the top and bottom of the bulk packing area are both open, and the upper elastic piston plate and the lower elastic piston plate are designed to be non-contact, which also simultaneously reduces the impact of frequent vibration of the lower elastic piston plate on the up and down movement of the upper elastic piston plate, so that the upper elastic piston plate can better move with the change of the solvent weight on the bulk packing body, reduce the impact of the vibration of the screen plate, and improve the accuracy of judging the solvent weight on the bulk packing body through the detection results of the distance sensor.

[0007] As a preferred embodiment of the packed tower for effectively separating ethyl chloride and hydrogen chloride provided by the present invention, an elastic mounting plate is provided at the bottom of the lower mesh plate and is mounted on the inner wall of the tower body. The elastic mounting plate is an elastic structure, which enables the bulk packing body to better move up and down synchronously with the change of the solvent amount, facilitating detection by the corresponding distance sensor.

[0008] As a preferred embodiment of the packed tower for effectively separating ethyl chloride and hydrogen chloride provided by the present invention, the top of the conduction rod extends out of the top of the mesh plate, and convex balls are provided on the upper and lower surfaces of the middle vibration plate, so as to facilitate the vibration of the conduction rod by the operation of the vibration motor. When the middle vibration plate vibrates synchronously, the convex balls on the middle vibration plate can drive several fillers in the bulk filler body to vibrate, thereby vibrating and discharging the retained solvent.

[0009] As a preferred embodiment of the packed tower for effectively separating ethyl chloride and hydrogen chloride provided by the present invention, a plurality of overflow troughs are provided, and a distribution port is provided at the bottom of the distribution box corresponding to each overflow trough. The solvent entering the distribution box is evenly dispersed to each overflow trough through the distribution port and overflows into the bulk packing area at the bottom through the multiple overflow troughs.

[0010] As a preferred embodiment of the packed tower for effectively separating ethyl chloride and hydrogen chloride provided by the present invention, an adjusting baffle is provided in the inner cavity of the distribution box and at the position corresponding to each distribution port, and multiple adjusting baffles are connected in series through a connecting plate. A telescopic part is installed on one side of one of the adjusting baffles. When it is necessary to control the flow of the distribution box entering the overflow trough, the adjusting baffle is pushed to move by controlling the operation of the telescopic part, and the adjusting baffle blocks the distribution port, thereby adjusting the flow entering the overflow trough.

[0011] As a preferred embodiment of the packed tower for effectively separating ethyl chloride and hydrogen chloride provided by the present invention, the separation intelligent controller is further provided with a flow control module, which is respectively connected to the processing module and the telescopic member by signal. When the solvent passing through the overflow trough enters the bulk packing body, the processing module determines the weight of the solvent flowing through the bulk packing body through the weight data detected by the weight detection mechanism, and calculates the difference with the weight of the solvent flowing through the overflow trough. When it is determined that the difference between the two is within a normal value, the processing module simultaneously determines the weight of the solvent flowing through the bulk packing body and compares it with the normal processing threshold (the normal processing value of the bulk packing body preset in the processing module). When it is determined that the weight is greater than the normal processing threshold, it is determined that the amount of solvent flowing into the bulk packing body through the overflow trough exceeds the normal processing range. At this time, the processing module sends a flow reduction signal to the flow control module, and the flow control module controls the telescopic member to operate. The operation of the telescopic member pushes the adjustment baffle to move to reduce the opening size of the distribution port, thereby reducing the amount of solvent flowing into the overflow trough, thereby automatically determining the solvent flow rate and automatically regulating the solvent flow rate to achieve an effective separation effect.

[0012] As a preferred embodiment of the packed tower for effectively separating ethyl chloride and hydrogen chloride provided by the present invention, a regulating ring is installed on the inner wall of the liquid inlet pipe, an regulating ball is arranged below the regulating ring, a buoyancy ball is fixed to the bottom of the regulating ball by an inserted rod, and the buoyancy ball is placed in the inner cavity of the distribution box.

[0013] As a preferred embodiment of the packed tower for effectively separating ethyl chloride and hydrogen chloride provided by the present invention, a plurality of overflow ports are provided on the upper end surface of the overflow trough, and the overflow trough has a square structure, which better disperses the solvent evenly to the bulk packing area through the plurality of overflow troughs, thereby improving the separation effect.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a packing tower for effectively separating ethyl chloride and hydrogen chloride. When the packing tower separates ethyl chloride and hydrogen chloride, the ethyl chloride can easily enter the distribution box through the liquid inlet pipe and overflow into the bulk packing area through the overflow trough, uniformly soaking the bulk packing body. During this process, the weight sensor detects the weight data of the solvent entering the overflow trough and sends it to the separation detection module in real time. The separation detection module sends the weight data to the processing module. The processing module determines the weight of the solvent flowing through the overflow trough through the weight data detected by the weight sensor. At the same time, the weight detection mechanism sends the detected weight data to the separation detection module. The separation detection module sends the corresponding weight data to the processing module. The processing module determines the weight of the solvent flowing through the bulk packing body through the weight data detected by the weight detection mechanism, and calculates the difference with the weight of the solvent flowing through the overflow trough. When it is determined that the difference between the two is within a normal value (the processing module has a preset normal value, the normal value is calculated). When the value is the normal difference between the solvent flowing through the overflow trough and the solvent flowing through the bulk packing body normally, it is judged that the solvent retained in the bulk packing body is within the normal range; when it is judged that the difference between the two is greater than the normal value, it is judged that the amount of solvent retained in the bulk packing body is too much, which is greater than the amount of solvent flowing out through the overflow trough. At this time, the processing module sends a control signal to the separation control module, and the separation module controls the vibration motor to work. The operation of the vibration motor drives the middle vibration plate to vibrate, thereby driving the bulk packing body to vibrate and make the retained solvent flow down smoothly, reducing the solvent retention. When the processing module determines that the difference between the weight of the solvent flowing through the bulk packing body and the weight of the solvent flowing through the overflow trough is within the normal value, the separation control module controls the vibration motor to stop working, thereby allowing the solvent to flow through the bulk packing body, automatically judge the solvent retention situation, and automatically control the retained solvent to vibrate and flow out, thereby improving the separation effect of the packing tower.

[0019] As described in the background technology, since the bulk packing area is usually composed of a number of individual packings with a certain shape, and the structure of the composition has no fixed shape, it is inevitable that some solvents cannot flow smoothly through the bulk packing area, and thus accumulate in the bulk packing area, affecting its full reaction with the gas and affecting the separation effect of the packed tower.

[0021] The present invention provides a packing tower for effectively separating ethyl chloride and hydrogen chloride. The packing tower comprises a separation intelligent controller 6, which automatically determines the amount of solvent remaining in the bulk packing body 12 using a processing module.

[0022] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein may be combined with each other.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings. Example

[0025] Please refer to Figure 1-Figure 7A packed tower for effectively separating ethyl chloride and hydrogen chloride comprises a tower body 1, a liquid distributor 4, a bulk packing area 5 and a separation intelligent controller 6. A lower inlet 2 is installed at the bottom of the tower body 1, and an upper inlet 3 is installed at the top of the tower body 1. The gas enters through the lower inlet 2 at the bottom, and the solvent enters through the upper inlet 3 at the top; the liquid distributor 4 is arranged in the tower body 1, and the liquid distributor 4 comprises a liquid inlet pipe 7 connected to the upper inlet 3, a distribution box 8 connected to the bottom output end of the liquid inlet pipe 7, and an overflow trough 9 connected to the bottom of the distribution box 8. A distribution port 15 is opened at the corresponding position of the distribution box 8 and the overflow trough 9. A weight sensor 18 is installed between the distribution box 8 and the overflow trough 9. The solvent enters the distribution box 8 through the liquid inlet pipe 7, and is evenly dispersed to each overflow trough 9 through the distribution box 8, and gradually overflows from the upper end of the overflow trough 9. The weight sensor 18 can detect the weight data of the solvent flowing into the overflow trough 9.

[0026] It is worth mentioning that see Figure 2-Figure 5 The bulk packing area 5 is arranged below the liquid distributor 4. The bulk packing area 5 includes a bulk packing body 12 and a mesh plate 10 and a lower mesh plate 11 respectively arranged at the upper and lower ends of the bulk packing body 12. The solvent overflowing from the upper end of the overflow trough 9 falls into the bulk packing area 5 at the bottom. The solvent passes through the bulk packing body 12 on the bulk packing area 5 and is evenly infiltrated on the surface of the bulk packing body 12, thereby fully contacting and reacting with the passing gas. A middle vibration plate 13 is installed in the middle of the bulk packing body 12. The upper end of the middle vibration plate 13 is installed with a vibration motor 1 through a conduction rod 17. 6. The vibration motor 16 drives the conduction rod 17 and the middle vibration plate 13 to vibrate, thereby driving the entire bulk filler body 12 to vibrate, so that the solvent retained in the bulk filler body 12 can flow down smoothly, reducing the situation where the solvent remains in the bulk filler body 12. A weight detection mechanism 19 is provided above the screen plate 10 and is installed on the inner wall of the tower body 1. The detection end of the weight detection mechanism 19 is connected to the screen plate 10 for detecting the weight data of the screen plate 10. The weight detection mechanism 19 can detect the overall weight of the bulk filler area 5 when the solvent flows through the bulk filler body 12.

[0027] In this embodiment, the separation intelligent controller 6 is arranged on one side of the tower body 1. The separation intelligent controller 6 is provided with a separation detection module, a processing module and a separation control module. The separation detection module is respectively connected to the weight sensor 18, the weight detection mechanism 19 and the processing module signal-connected, the processing module is signal-connected to the separation control module, and the separation control module is signal-connected to the vibration motor 16. When the packing tower separates ethyl chloride and hydrogen chloride, it is easy to enter the distribution box 8 through the liquid inlet pipe 7 and overflow into the bulk packing area 5 through the overflow trough 9, uniformly infiltrating the bulk packing body 12. In this process, the weight sensor 18 will detect the weight data of the solvent entering the overflow trough 9 and send it to the separation detection module in real time. The separation detection module sends the weight data to the processing module. The processing module determines the weight of the solvent flowing through the overflow trough 9 by the weight data detected by the weight sensor 18. At the same time, the weight detection mechanism 19 sends the detected weight data to the separation detection module. The separation detection module sends the corresponding weight data to the processing module. The processing module determines the weight of the solvent flowing through the bulk packing body 12 by the weight data detected by the weight detection mechanism 19. The amount of solvent remaining in the bulk filler body 12 is determined to be within the normal range. If the difference between the two values ​​is greater than the normal value, the amount of solvent remaining in the bulk filler body 12 is determined to be excessive and greater than the amount of solvent flowing out of the overflow tank 9. At this time, the processing module sends a control signal to the separation control module, and the separation module controls the vibration. The motor 16 is working, and the vibration motor 16 drives the middle vibration plate 13 to vibrate, thereby driving the bulk packing body 12 to vibrate and make the retained solvent flow down smoothly, reducing the solvent retention. When the processing module determines that the weight difference between the solvent flowing through the bulk packing body 12 and the solvent flowing through the overflow tank 9 is at a normal value, the separation control module controls the vibration motor 16 to stop working, thereby making the solvent flow through the bulk packing body 12, automatically judging the solvent retention situation, and automatically controlling the retained solvent to vibrate out, thereby improving the separation effect of the packing tower.

[0028] It is worth mentioning that Figure 6As shown, the weight detection mechanism 19 includes a detection cylinder 25 installed on the inner wall of the tower body 1, a lower elastic piston plate 28 and an upper elastic piston plate 29 which are respectively connected to the inner wall of the detection cylinder 25 in a vertical sliding manner. The bottom of the lower elastic piston plate 28 is connected to the screen plate 10 through a connecting rod 27, and the upper elastic piston plate 29 is placed above the lower elastic piston plate 28. A distance sensor 26 installed on the inner wall of the detection cylinder 25 is provided above the upper elastic piston plate 29. The separation detection module is connected to the distance sensor 26 signal. When the solvent enters the bulk filler body 12, the overall weight of the screen plate 10, the bulk filler body 12 and the lower screen plate 11 will increase. At this time, the screen plate 10 drives the connecting rod 27 and the lower elastic piston plate 28 to move downward, and the pressure between the lower elastic piston plate 28 and the upper elastic piston plate 29 is reduced, thereby driving the upper elastic piston plate 29 to move downward synchronously. At this time, the displacement distance data of the upper elastic piston plate 29 is detected by the distance sensor 26 and sent For the separation detection module, the processing module can calculate the solvent value corresponding to the flow through the bulk filler body 12 through the distance data sent by the distance sensor 26, thereby judging the solvent value flowing through the bulk filler body 12, and by setting the lower elastic piston plate 28, the lower elastic piston plate 28 is an elastic material, which can drive the screen plate 10 to vibrate when the vibration motor 16 is working for preliminary filtering, and a buffer solution is filled between the lower elastic piston plate 28 and the upper elastic piston plate 29. The top and bottom of the bulk filler area 5 are both open settings, and the upper elastic piston plate 29 and the lower elastic piston plate 28 are non-contact designs, which also simultaneously reduce the impact of the frequent vibration of the lower elastic piston plate 28 on the up and down movement of the upper elastic piston plate 29, so that the upper elastic piston plate 29 can better move with the change of the solvent weight on the bulk filler body 12, reducing the impact of the vibration of the screen plate 10, and improving the accuracy of judging the solvent weight on the bulk filler body 12 through the detection results of the distance sensor 26.

[0029] In addition, an elastic mounting plate 14 is provided at the bottom of the lower mesh plate 11 and is installed with the inner wall of the tower body 1. The elastic mounting plate 14 is an elastic structure, so that the bulk filler body 12 can better move up and down synchronously with the different amounts of solvent, which is convenient for detection by the corresponding distance sensor 26. The top of the conduction rod 17 extends out of the top of the mesh plate 10, and the upper and lower surfaces of the middle vibration plate 13 are provided with convex balls, which are convenient for driving the conduction rod 17 to vibrate through the operation of the vibration motor 16. When the middle vibration plate 13 vibrates synchronously, the convex balls on the middle vibration plate 13 can drive several fillers in the bulk filler body 12 to vibrate, and the retained solvent can be vibrated and discharged. A plurality of overflow ports are provided on the upper end face of the overflow trough 9, and the overflow trough 9 is a square structure, which can better disperse the solvent evenly to the bulk filler area 5 through multiple overflow troughs 9, thereby improving the separation effect. Example

[0030] The packed tower for effectively separating ethyl chloride and hydrogen chloride provided in Example 1 is further optimized. The difference from Example 1 is that, specifically, Figure 7 and Figure 8 As shown, there are multiple overflow grooves 9, and a distribution port 15 is opened at the bottom of the distribution box 8 corresponding to each overflow groove 9. The solvent entering the distribution box 8 is evenly dispersed to each overflow groove 9 through the distribution port 15, and overflows to the bulk filler area 5 at the bottom through multiple overflow grooves 9.

[0031] In this embodiment, an adjustment baffle 21 is provided at the inner cavity of the distribution box 8 and corresponding to each distribution port 15. Multiple adjustment baffles 21 are connected in series through connecting plates. A telescopic member 20 is installed on one side of one of the adjustment baffles 21. When it is necessary to control the flow of the distribution box 8 entering the overflow trough 9, the adjustment baffle 21 is pushed to move by controlling the operation of the telescopic member 20, and the adjustment baffle 21 blocks the distribution port 15, thereby adjusting the flow entering the overflow trough 9.

[0032] It is worth mentioning that the separation intelligent controller 6 is also provided with a flow control module, which is respectively connected to the processing module and the telescopic member 20 by signal. When the solvent passing through the overflow tank 9 enters the bulk filler body 12, the processing module judges the weight of the solvent flowing through the bulk filler body 12 through the weight data detected by the weight detection mechanism 19, and calculates the difference with the weight of the solvent flowing through the overflow tank 9. When it is judged that the difference between the two is at a normal value, the processing module judges the weight of the solvent flowing through the bulk filler body 12 and compares it with the normal processing threshold (the normal processing value of the bulk filler body 12 preset in the processing module). When it is judged to be greater than the normal processing threshold, it is determined that the amount of solvent flowing into the bulk filler body 12 through the overflow tank 9 exceeds the normal processing range. At this time, the processing module sends a flow reduction signal to the flow control module, and the flow control module controls the telescopic member 20 to work. The telescopic member 20 works to push the adjustment baffle 21 to move to reduce the opening size of the distribution port 15, thereby reducing the amount of solvent flowing into the overflow tank 9, thereby automatically judging the flow rate of the solvent and automatically regulating the solvent flow rate to achieve an effective separation effect.

[0033] In addition, a regulating ring 22 is installed on the inner wall of the liquid inlet pipe 7, and an regulating ball 23 is arranged below the regulating ring 22. A buoyancy ball 24 is fixed to the bottom of the regulating ball 23 by an inserted rod. The buoyancy ball 24 is placed in the inner cavity of the distribution box 8. When the opening size of the distribution port 15 on the distribution box 8 is reduced through regulation, in order to prevent the solvent from overflowing through the distribution box 8, the solvent in the distribution box 8 will push the buoyancy ball 24 upward, and the buoyancy ball 24 will simultaneously push the regulating ball 23 upward to seal the opening on the regulating ring 22, thereby reducing the outflow of the liquid inlet pipe 7 and preventing the solvent from overflowing in the distribution box 8.
