Description

Technical Field

[0001] The present invention relates to the technical field of recovery and treatment of organic chemical waste liquid, and specifically relates to an acidic waste recycling device. Background Technique

[0002] During the production process of trichloroethylene, organic waste containing acid and water will be discharged during the maintenance, sampling, filling, startup and shutdown processes in the production process. To avoid direct discharge of organic waste, which reduces the yield and causes environmental pollution, generally, waste liquid recovery and storage facilities are first set up, and then the waste liquid is treated by waste liquid treatment facilities through acid and water removal facilities for utilization.

[0003] The traditional treatment process flow includes equipment and facilities such as neutralization treatment, static separation, and drying and dehydration. The original neutralization disposal method uses a neutralization reaction kettle. The low-boiling tower top liquid, intermediate tower top liquid, waste liquid discharged from the separation pump area, waste liquid discharged from the filling pump in the finished product tank area, and abnormal discharge recovery materials and dilute alkali liquid enter the neutralization reaction kettle through the feed pipe. Through adding alkali, stirring, neutralizing and standing for a period of time for natural sedimentation to achieve layered separation for recovery. However, there is a problem that after long-term use, dirt will adhere to the inner wall of the feed pipe of the existing neutralization reaction kettle, and at this time, it is necessary to stop the machine for cleaning, which affects the waste liquid treatment efficiency. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the present invention provides an acidic waste recycling device, which solves the problem that after long-term use, dirt will adhere to the inner wall of the feed pipe of the existing neutralization reaction kettle, and at this time, it is necessary to stop the machine for cleaning, which affects the waste liquid treatment efficiency.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the present invention provides the following technical solution: An acidic waste recycling device includes a sedimentation reactor. A reaction chamber is provided inside the sedimentation reactor. A main feed pipe for discharging organic chemical waste liquid containing acid and water is integrated at the middle position of the sedimentation reactor. A sub-feed pipe is integrated at the part of the main feed pipe entering the reaction chamber. The top end of the sub-feed pipe extends into the inner cavity of the main feed pipe and is in communication with the inner cavity of the main feed pipe. An ear plate is fixed at the part of the sub-feed pipe entering the inner cavity of the main feed pipe. An installation shaft is rotatably connected to the ear plate. A partition plate is fixed on the installation shaft. When the partition plate rotates to abut against the end of the sub-feed pipe, it closes the sub-feed pipe. When the partition plate rotates to abut against the inner cavity groove wall of the main feed pipe, it closes the main feed pipe. A control component for controlling the rotation of the installation shaft is provided on the main feed pipe. An upper drain pipe communicating with the reaction chamber is integrated on the upper side of the sedimentation reactor, and a lower drain pipe communicating with the reaction chamber is integrated on the lower side.

[0008] Through the above technical scheme, low-boiling tower top liquid, intermediate tower top liquid, waste liquid discharged from the separation pump area, waste liquid discharged from the filling pump in the finished product tank area, abnormally discharged recovered materials, dilute alkali liquid, etc. are discharged into the reaction chamber through the main feed pipe. After sufficient natural separation, the aqueous phase is returned to the dilute alkali tank for recycling through the upper discharge pipe, and the organic phase is discharged from the lower discharge pipe to the tail water pool. In the initial state, the partition and the branch feed pipe extend to the inner end of the main feed pipe to collide with each other to close the branch feed pipe, and the low-boiling tower top liquid, intermediate tower top liquid, waste liquid discharged from the separation pump area, waste liquid discharged from the filling pump in the finished product tank area, abnormally discharged recovered materials, dilute alkali liquid, etc. are discharged into the reaction chamber through the main feed pipe. The raw materials and dilute alkali liquid will not enter the sub-feed pipe. After long-term use, when the dirt adheres to the inner wall of the main feed pipe and affects the discharge efficiency of the main feed pipe, the control component provides power to drive the installation shaft and the partition of the integrated structure to rotate, so that the partition rotates to contact the inner wall of the main feed pipe to close the main feed pipe. At this time, the low-boiling tower top liquid, the intermediate tower top liquid, the waste liquid discharged from the separation pump area, the waste liquid discharged from the filling pump in the finished product tank area, the abnormally discharged recovered materials, and the dilute alkali liquid will enter the sub-feed pipe, which will not affect the discharge, and the main feed pipe can be cleaned without stopping the machine.

[0027] (III) Beneficial effects

[0028] The present invention provides an acid waste recovery device having the following beneficial effects:

[0029] (1) In the acid waste recovery equipment, low-boiling tower top liquid, intermediate tower top liquid, waste liquid discharged from the separation pump area, waste liquid discharged from the filling pump in the finished product tank area, abnormally discharged recovered materials, dilute alkali liquid, etc. are discharged into the reaction chamber through the main feed pipe. After sufficient natural separation, the aqueous phase is returned to the dilute alkali tank for recycling through the upper discharge pipe, and the organic phase is discharged from the lower discharge pipe to the tail water tank.

Recycled materials and dilute alkali liquid will not enter the sub-feed pipe. After long-term use, when dirt adheres to the inner wall of the main feed pipe and affects the discharge efficiency of the main feed pipe, the control component provides power to drive the mounting shaft and partition of the integrated structure to rotate, so that the partition rotates until it contacts the inner wall of the main feed pipe to close the main feed pipe. At this time, low-boiling tower top liquid, intermediate tower top liquid, waste liquid discharged from the separation pump area, waste liquid discharged from the filling pump in the finished product tank area, abnormally discharged recycled materials, and dilute alkali liquid will enter the sub-feed pipe, which will not affect the discharge and the main feed pipe can be cleaned without stopping the machine.

Detailed implementation manners

[0042] 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.

[0043] As Figures 1-9 shown, the present invention provides a technical solution: an acidic waste recycling device, including a buffer tank 1 for accommodating recycled low boiling tower top liquid, intermediate tower top liquid, separation pump area discharge waste liquid, finished product tank area filling pump discharge waste liquid, and abnormally discharged recycled materials, a dilute alkali tank 2 for accommodating dilute alkali liquid, a pipeline mixer 3, a waste liquid cooler 4, a sedimentation reactor 5, and a tail water tank 6. The dilute alkali tank 2 serves as an alkali circulation tank and at the same time serves as an aqueous phase self-reflux tank.

[0044] As Figure 1, the discharge port end of the buffer tank 1 is connected to the feed port of the first transfer pump through a pipeline, the discharge port of the first transfer pump is connected to one of the feed ports of the pipe mixer through a pipeline, the discharge port of the dilute alkali tank 2 is connected to the feed port of the second transfer pump through a pipeline, the discharge port of the second transfer pump is connected to the other feed port of the pipe mixer through a pipeline, the discharge port of the pipe mixer is connected to the feed port of the waste liquid cooler 4 through a pipeline, the discharge port of the waste liquid cooler 4 is connected to the feed port end of the main feed pipe 8 of the sedimentation reactor 5 through a pipeline, the upper drain pipe 12 of the sedimentation reactor 5 is connected to the feed port of the dilute alkali tank 2 through a pipeline, the lower drain pipe 13 of the sedimentation reactor 5 is connected to the feed port of the tail water tank 6 through a pipeline, and regulating valves and flow meters for controlling the pipeline flow rate are provided on each pipeline.

[0045] As Figure 1 , the alkali liquid is fully stirred and mixed in the dilute alkali tank 2 at 32% and water at a volume ratio of 10:1 to prepare a dilute alkali liquid with a concentration of about 3%-4% for standby. The waste liquid in the buffer tank 1 and the dilute alkali liquid in the dilute alkali tank are filled into the pipe mixer 3 at a volume ratio of 3:1. After being fully mixed by the pipe mixer 3, it enters the upper 1 / 3 depth of the reaction chamber 7 of the sedimentation reactor 5 through a pipeline. Before the liquid level is established in the sedimentation reactor 5 and the overflow port is not reached, the total flow rate can be appropriately increased. When the total volume of the incoming liquid is slightly up to 7.5 cubic meters, adjust the incoming liquid flow rate and observe the overflow liquid conditions of the upper drain pipe 12 and the lower drain pipe 13. When overflow liquid can be seen in the upper drain pipe 12 or the lower drain pipe 13, stop feeding and start static sedimentation. After standing for eight hours, re-establish normal continuous sedimentation and continuous discharging operations at a flow rate of about 450 liters per hour of the organic waste liquid and at a volume ratio of the organic waste liquid to the dilute alkali liquid of 3:1. After the sedimentation cycle is established normally, analyze the acidity of the organic waste liquid and adjust the volume ratio of the incoming alkali operation until the acidity of the organic waste liquid is lower than 0.002%. During operation, appropriately maintain the liquid level of the buffer tank 1 and observe its acid content. It is absolutely prohibited to feed materials into the sedimentation reactor 5 when the materials in the buffer tank 1 are completely acid. The observation and detection means all adopt existing equipment, such as a pH value automatic analyzer, etc., so no more details will be described here.

[0046] As Figure 1 , after sufficient natural separation, the aqueous phase overflows from the upper drain pipe 12 to the dilute alkali tank 2 for recycling, the organic phase enters the tail water tank 6 after maintaining a certain liquid seal height through the lower drain pipe 13. The organic matter in the tail water tank 6 that has been deacidified and separated from water returns directly to the desorption kettle liquefaction tank for reuse. The salt mud sedimented and separated at the bottom of the reaction chamber 7 is discharged to the recovery bucket through the sludge discharge pipe 14, and the organic matter is recovered again after sufficient static sedimentation. The remaining salt mud containing organic matter is centrally collected and treated as hazardous waste. Using the dilute alkali liquid as a neutralizing agent and an extraction agent, and utilizing the density difference and head difference between the aqueous phase and the organic phase for separation, the automation level of the device is greatly improved.

[0047] AsFigure 2 and Figure 3 and Figure 4 and Figure 5 , a sedimentation reactor (5) is internally provided with a reaction chamber (7). At the middle position of the sedimentation reactor (5), a main feed pipe (8) for discharging the acid-containing and water-containing organic waste of organic chemical industry is integrally formed. A sub-feed pipe (9) is integrally formed at the part of the main feed pipe (8) entering the reaction chamber (7). The top end of the sub-feed pipe (9) extends into the inner cavity of the main feed pipe (8) and is in communication with the inner cavity of the main feed pipe (8). An ear plate is fixed at the part of the sub-feed pipe (9) entering the inner cavity of the main feed pipe (8). A mounting shaft (10) is rotatably connected to the ear plate. A partition plate (11) is fixed on the mounting shaft (10). When the partition plate (11) rotates to abut against the end of the sub-feed pipe (9), the sub-feed pipe (9) is closed. When the partition plate (11) rotates to abut against the inner cavity wall of the main feed pipe (8), the main feed pipe (8) is closed. A control assembly (17) for controlling the rotation of the mounting shaft (10) is provided on the main feed pipe (8). An upper drain pipe (12) communicating with the reaction chamber (7) is integrally formed on the upper side of the sedimentation reactor (5), and a lower drain pipe (13) communicating with the reaction chamber (7) is integrally formed on the lower side.

[0048] Such as Figure 2 and Figure 3 and Figure 4 and Figure 5 , the low-boiling tower top liquid, the intermediate tower top liquid, the waste liquid discharged from the separation pump area, the waste liquid discharged from the filling pump in the finished product tank area, the recovered material from abnormal discharge, the dilute alkali solution, etc. are discharged into the reaction chamber (7) through the main feed pipe (8). After sufficient natural separation, the aqueous phase returns to the dilute alkali tank (2) through the upper drain pipe (12) for recycling, and the organic phase goes to the tail water pool (6) through the lower drain pipe (13). In the initial state, the partition plate (11) abuts against the inner end of the sub-feed pipe (9) extending into the main feed pipe (8) to close the sub-feed pipe (9). The low-boiling tower top liquid, the intermediate tower top liquid, the waste liquid discharged from the separation pump area, the waste liquid discharged from the filling pump in the finished product tank area, the recovered material from abnormal discharge, and the dilute alkali solution will not enter the sub-feed pipe (9). After long-term use, when dirt adheres to the inner cavity wall of the main feed pipe (8) and affects the discharge efficiency of the main feed pipe (8), power is provided by the control assembly (17) to drive the integrally structured mounting shaft (10) and the partition plate (11) to rotate, so that the partition plate (11) rotates to abut against the inner wall of the main feed pipe (8) to close the main feed pipe (8). At this time, the low-boiling tower top liquid, the intermediate tower top liquid, the waste liquid discharged from the separation pump area, the waste liquid discharged from the filling pump in the finished product tank area, the recovered material from abnormal discharge, and the dilute alkali solution will enter the sub-feed pipe (9), without affecting the discharge, and the main feed pipe (8) can be cleaned without stopping the machine.

[0049] Such as Figure 2 and Figure 3 and Figure 4 and Figure 5, by utilizing the physical principle that the organic phase and the inorganic phase can automatically separate layers, through establishing the liquid separation height of the organic phase and the inorganic phase, the automatic separation of organic substances from the waste liquid containing acid and water is realized, greatly improving the automation level of the device. After the transformation, the facility has changed from the original intermittent operation to continuous operation, greatly improving the processing capacity of the original device. The water removal effect of the transformed device is more reliable and stable than before. The water content of the treated material meets the process requirements, and the original device's drying and water removal facilities are cancelled, which not only reduces the generation amount of the original process hazardous waste but also reduces the fouling source of the rectification tower packing from the process source. The number of new process equipment and electrical instruments after the transformation is reduced, which will greatly reduce the maintenance workload at the production site.

[0050] Such as Figure 4 and Figure 5 , a protective pipe 15 penetrates through the sedimentation reactor 5 and is located outside the main feed pipe 8 and the sub-feed pipe 9. The outer wall of the protective pipe 15 is fixedly connected to the sedimentation reactor 5. The top of the main feed pipe 8 is fixedly connected to the inner wall of the protective pipe 15, and the outer wall of the sub-feed pipe 9 and the inner wall of the protective pipe 15 are fixedly connected through a number of cross bars. The gap between the protective pipe 15 and the main feed pipe 8 and the sub-feed pipe 9 is an installation groove 16. The control assembly 17 is located in the installation groove 16. The control assembly 17, the main feed pipe 8, and the sub-feed pipe 9 are protected and supported by the protective pipe 15. The protective pipe 15 is sleeved outside the main feed pipe 8 and the sub-feed pipe 9 and is fixedly connected to the main feed pipe 8 and the sub-feed pipe 9. A number of cross bars are located above the control assembly 17 and do not affect the operation of the control assembly 17.

[0051] Such as Figure 4 and Figure 5 and Figure 6 and Figure 7 , both ends of the installation shaft 10 pass through the sub-feed pipe 9 and the main sub-feed pipe and are rotatably connected to the sub-feed pipe 9 and the main sub-feed pipe. The end of the installation shaft 10 passing through the sub-feed pipe 9 enters the installation groove 16 and is rotatably connected to the groove wall of the installation groove 16. The control assembly 17 includes racks 1701 respectively arranged on both sides of the inner cavity groove wall of the installation groove 16. The racks 1701 are slidably connected to the groove wall of the installation groove 16 through slide rails. A gear 1702 meshing with the rack 1701 is arranged beside each rack 1701. The two gears 1702 are respectively nested outside the two ends of the installation shaft 10 entering the installation groove 16 and are coaxially fixed to the installation shaft 10. Two driving components for controlling the vertical movement of adjacent racks 1701 are also arranged in the installation groove 16.

[0052] Such as Figure 4 and Figure 5 and Figure 6 and Figure 7, powered by a driving component, drives each adjacent rack 1701 to move in the vertical direction. When the rack 1701 moves upward, it drives the gear 1702 meshing with the rack 1701 to rotate counterclockwise. The counterclockwise rotation of the gear 1702 drives the mounting shaft 10 fixedly connected to the gear 1702 coaxially to rotate counterclockwise, thereby driving the partition plate 11 to rotate and realizing shunt. Both ends of the mounting shaft 10 are connected to the sub-feed pipe 9 and the main sub-feed pipe through sealed bearings, reducing the possibility of sewage and dirt in the main feed pipe 8 and the sub-feed pipe 9 entering the installation groove 16, and reducing the possibility of dirt affecting the working life of the motor, connecting rope 1711, gear 1702, rack 1701, etc.

[0053] Such as Figure 4 and Figure 5 and Figure 6 and Figure 7 , the motor, drive shaft 1704, upper wire reel 1705, lower wire reel 1706, mounting seat 1703, first fixed pulley 1707, second fixed pulley 1708, movable pulley 1710, connecting rope 1711, gear 1702, rack 1701, mounting shaft 10, and partition plate 11 are all made of waterproof and anti-corrosion materials.

[0054] Such as Figure 6 and Figure 7 , the driving component includes a mounting seat 1703 fixed on the inner cavity wall of the installation groove 16. A drive shaft 1704 is rotatably connected to the mounting seat 1703. Two upper wire reels 1705 and lower wire reels 1706 coaxially fixed to the drive shaft 1704 are nested outside the drive shaft 1704. The diameter of the upper wire reel 1705 is larger than that of the lower wire reel 1706. A first fixed pulley 1707 is rotatably connected to one side of the mounting seat 1703, and a second fixed pulley 1708 is rotatably connected to the other end. A moving seat 1709 is integrated at the top of the rack 1701. The moving seat 1709 is slidably connected to the wall of the installation groove 16. A movable pulley 1710 is rotatably connected to the moving seat 1709.

[0055] Such as Figure 6 and Figure 7 , the mounting seat 1703 is fixedly connected to the inner cavity wall of the installation groove 16 and is located above the rack 1701 to support the upper wire reel 1705, lower wire reel 1706, first fixed pulley 1707, and second fixed pulley 1708. Through the cooperation of the upper wire reel 1705, lower wire reel 1706, first fixed pulley 1707, second fixed pulley 1708, and movable pulley 1710, the rack 1701 with an integrated structure with the moving seat 1709 is driven to move in the vertical direction.

[0056] Such as Figure 6 and Figure 7, a connecting rope 1711 is wound around the outside of the movable pulley 1710. Both ends of the connecting rope 1711 bypass the movable pulley 1710. One end of the connecting rope 1711 that bypasses the movable pulley 1710 bypasses the first fixed pulley 1707. One end of the connecting rope 1711 that bypasses the first fixed pulley 1707 is wound around the outside of the upper wire reel 1705 and its end is fixed to the outer wall of the upper wire reel 1705. The other end of the connecting rope 1711 that bypasses the movable pulley 1710 bypasses the second fixed pulley 1708. The other end that bypasses the second fixed pulley 1708 is wound around the outside of the lower wire reel 1706 and is fixed to the lower wire reel 1706. A motor for controlling the rotation of the drive shaft 1704 is fixed in the installation groove 16. A counterweight is fixed to the bottom end of the movable seat 1709. The bottom end of the counterweight is fixed to the rack 1701. By setting the counterweight, the stability of the movement of the rack 1701 is improved.

[0057] As Figure 4 and Figure 5 and Figure 6 and Figure 7 , power is provided by the motor to drive the drive shaft 1704 coaxially fixed to the output shaft of the motor to rotate. The rotation of the drive shaft 1704 will drive the upper wire reel 1705 and the lower wire reel 1706 coaxially fixed to the drive shaft 1704 to rotate. The rotation of the upper wire reel 1705 and the lower wire reel 1706 will control the movement of the connecting rope 1711, thereby driving the vertical movement of the movable seat 1709, and thus driving the vertical movement of the rack 1701.

[0058] As Figure 3 , a main annular sealing plate and a sub-annular sealing plate are fixed to the bottom end of the protection tube 15. The main annular sealing plate seals the gap between the bottom end of the protection tube 15 and the bottom end of the main feed pipe 8. The sub-annular sealing plate seals the gap between the bottom end of the protection tube 15 and the sub-feed pipe. The annular sealing plate seals the bottom of the installation groove 16, reducing the possibility of waste liquid entering the installation groove 16.

[0059] As Figure 3 and Figure 8 and Figure 9 , a vertical long rod 18 is fixed to the bottom end of each rack 1701. Two connection grooves adapted to the long rod 18 are provided on the main annular sealing plate. The bottom end of the long rod 18 passes through the main annular sealing plate through the connection groove and is slidably connected to the connection groove. A cleaning assembly 19 for cleaning the inner wall of the main feed pipe 8 is fixed to one end of the two long rods 18 passing through the main annular sealing plate. When the rack 1701 moves upward, it will drive the cleaning assembly 19 to move upward. The cleaning assembly 19 moves upward and abuts against the inner wall of the main feed pipe 8 to clean the inner wall of the main feed pipe 8, facilitating the subsequent use of the main feed pipe 8. A rubber sealing ring for reducing the passage of sewage and dirt into the installation groove 16 through the gap between the connection groove and the long rod 18 is fixed to the connection groove, and the rubber sealing ring does not affect the movement of the long rod 18.

[0060] AsFigure 3 and Figure 8 and Figure 9 For cleaning component 19, it includes two outer annular plates 1901 fixed to the main annular seal plate part extending from two long rods 18. An inner annular plate 1902 is arranged inside the outer annular plate 1901 at the bottom end. The inner annular plate 1902 and the adjacent outer annular plate 1901 are fixedly connected by a number of uniformly arranged support rods 1903. At the top of the inner annular plate 1902, there is an annular scraping plate 1904 for cleaning the main feed pipe 8. The annular scraping plate 1904 and the inner annular plate 1902 are fixedly connected by a number of uniformly arranged vertical rods 1905. The annular scraping plate 1904, the inner annular plate 1902, and the outer annular plate 1901 are coaxially arranged.

[0061] Such as Figure 3 and Figure 8 and Figure 9 For, the movement of the rack 1701 in the vertical direction will drive the movement of the long rod 18 which is an integral structure with the rack 1701. The movement of the long rod 18 will drive the movement of the outer annular plate 1901, the support rod 1903, the inner annular plate 1902, the vertical rod 1905, and the annular scraping plate 1904 which are integral structures with the long rod 18. The annular scraping plate 1904 fits against the inner wall of the main feed pipe 8, facilitating the scraping of dirt adhering to the inner wall of the main feed pipe 8.

[0062] Such as Figure 2 and Figure 3 For, an annular baffle 20 is integrally formed on the upper side of the reaction chamber 7 and is located below the upper drain pipe 12. The outer wall of the annular baffle 20 is fixed to the groove wall of the reaction chamber 7. An overflow weir 21 is provided on the annular baffle 20. By providing the annular baffle 20 and the overflow weir 21, the liquid overflows evenly. This is an existing structure, so it will not be elaborated here too much.

[0063] Such as Figure 2 and Figure 3 For, the bottom of the reaction chamber 7 is inverted conical. A sludge discharge pipe 14 which is integrally formed at the middle position of the bottom of the sedimentation reactor 5 and communicates with the reaction chamber 7. The communicating end of the sludge discharge pipe 14 with the reaction chamber 7 is located at the lowest end of the reaction chamber 7. During long-term use, a small amount of salt sludge will be generated at the bottom of the sedimentation reactor 5 and is discharged through the sludge discharge pipe 14.

[0064] In use, power is connected and the switch is turned on. After the device has been used for a period of time, the motor is turned on. Power is provided by the motor to drive the rotation of the drive shaft 1704. The rotation of the drive shaft 1704 drives the rotation of the upper wire reel 1705 and the lower wire reel 1706 that are coaxially fixed to the drive shaft 1704. The winding directions of the connecting ropes 1711 wound around the upper wire reel 1705 and the lower wire reel 1706 are opposite, and the diameter of the wire winding groove of the upper wire reel 1705 is larger than that of the lower wire reel 1706. When the drive shaft 1704 rotates clockwise, the upper wire reel 1705 drives the connecting rope 1711 to be recycled and wound outside the upper wire reel 1705, and the lower wire reel 1706 drives the connecting rope 1711 to pay out and leave the lower wire reel 1706. Due to the diameter difference, the movable pulley 1710 wound around the connecting rope 1711 and the moving seat 1709 rotatably connected to the movable pulley 1710 will be slowly driven to move upward. The upward movement of the moving seat 1709 drives the counterweight block, the rack 1701 and the long rod 18 that are of an integral structure with the moving seat 1709 to move upward;

[0065] The upward movement of the rack 1701 drives the rotation of the gear 1702 meshing with the rack 1701. The rotation of the gear 1702 drives the rotation of the mounting shaft 10 coaxially fixed to the gear 1702. The rotation of the mounting shaft 10 drives the rotation of the partition plate 11 fixed to the mounting shaft 10. The partition plate 11 rotates until it abuts against the inner wall of the main feed pipe 8 to close the main feed pipe 8. At this time, the low-boiling-point top liquid, the intermediate-top liquid, the waste liquid discharged from the separation pump area, the waste liquid discharged from the filling pump in the finished product tank area, the recycled material of the abnormal discharge, and the dilute alkali liquid will enter the sub-feed pipe 9;

[0066] At the same time, the upward movement of the rack 1701 drives the upward movement of the long rod 18 fixed to the rack 1701. The upward movement of the long rod 18 drives the upward movement of the outer annular plate 1901, the inner annular plate 1902, the annular scraping plate 1904, and the vertical rod 1905 that are of an integral structure with the long rod 18. The annular scraping plate 1904 moves upward into the inner wall of the main feed pipe 8 and abuts against the inner wall of the main feed pipe 8. The dirt on the inner wall of the main feed pipe 8 is cleaned and scraped by the annular scraping plate 1904. After the cleaning is completed, the motor drives the drive shaft 1704 to rotate in the reverse direction, so that the mounting shaft 10 rotates in the reverse direction until it abuts against the inner end of the sub-feed pipe 9 extending into the main feed pipe 8 to close the sub-feed pipe 9. The low-boiling-point top liquid, the intermediate-top liquid, the waste liquid discharged from the separation pump area, the waste liquid discharged from the filling pump in the finished product tank area, the recycled material of the abnormal discharge, and the dilute alkali liquid continue to be discharged into the reaction chamber 7 through the main feed pipe 8. This is the use process of the acidic waste recycling equipment. At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
