Description

Technical Field

[0001] The invention belongs to the technical field of crude benzene separation, and in particular relates to a crude benzene solid impurity separation and processing system and a processing method. Background Art

[0002] Crude benzene comes from coal tar. The formation of coal tar is a complex process. When coal is isolated from air and heated, it will produce coke, raw gas and other substances. This process is called high-temperature coking. The product obtained by high-temperature coking is mainly coke, and coal tar is a by-product obtained by high-temperature coking. When coal is pyrolyzed at high temperature in an air-isolated state, the pyrolysis products produced enter the top space of the coke oven through the middle of the carbonization chamber, and the other part enters the gap on the top of the furnace along the edge of the furnace wall of the carbonization chamber. This process is the process of forming crude tar. Benzene compounds are recovered from the coke oven gas after deammoniation / dehydration of the crude tar, among which crude benzene is mainly composed of benzene, toluene and xylene.

[0003] Chinese invention patent CN117797518A relates to a diversion type crude benzene oil-water separation device and a crude benzene oil-water separation method, the device includes a separator body and a partition baffle, an inlet liquid guide pipe and a diversion collector arranged in the separator body; the separation equipment has low separation efficiency and poor separation effect.

[0004] Chinese invention patent CN108970199A discloses a crude benzene filter with high filtration efficiency, including a filter housing, the top of which is fixedly connected to a liquid inlet pipe, and the top of the inner wall of the filter housing is fixedly connected to a first mounting shell at a position corresponding to the opening of the liquid inlet pipe; the filter is difficult to operate and cannot meet the needs of mass production.

[0005] At present, the common crude benzene distillation (rather than distillation) methods in the coking industry generally include the atmospheric pressure superheated steam stripping method for crude benzene distillation and the negative pressure superheated steam stripping method for crude benzene distillation. Because the distillation method is not adopted, the crude benzene must contain a certain amount of carbon particles or coal-like substances, which will bring great harm to the subsequent storage and production.

[0006] Taking a 100,000-ton crude benzene hydrogenation unit as an example, the raw material storage tank must be cleaned every two years to remove about 30 to 50 tons of "oil sludge". The cleaning process not only pollutes the environment, but also has caused safety accidents such as "fires" in some companies. Materials containing "oil sludge" particles enter subsequent hydrogenation units and accumulate in the catalyst gaps in the liquid phase reactor, thereby affecting the performance of the catalyst. The unit must be shut down every 2 to 3 years and will inevitably go through cooling, material withdrawal, catalyst passivation, partial catalyst replacement, system recovery, catalyst sulfidation, and reheating to start up, thereby reducing production efficiency and sustainability.

[0007] When crude benzene is separated from impurities, it flows above the filter and filters and recovers the oil phase. However, since the inlet and outlet directions of crude benzene are fixed, crude benzene is easily accumulated on one side above the filter, thereby reducing the separation efficiency and affecting the recovery accuracy of the oil phase.

[0008] At the same time, when the crude benzene is subsequently separated with the help of high-temperature steam, since the steam inlet direction is fixed and the steam flow direction inside the separation chamber is unstable, the high-temperature separation efficiency of the high-temperature steam on the impurities inside the filter is uneven, thereby reducing the separation effect of the oil phase in the impurities.

[0009] When the impurities are cleaned with clean water, due to the fixed stirring direction, the clean water is prone to tangential rotation and swirling inside the separation chamber, which will reduce the cleaning effect of the impurities inside the filter and easily cause pollution to the subsequent impurity separation of crude benzene.

[0024] The processing method of the crude benzene solid impurity separation and processing system as described above comprises the following steps:

[0025] S1. After crude benzene enters the separation chamber and is filtered by the filter screen, the oil phase continuously flows downward for recovery.

[0032] 3. The present application sets up the cooperation of components such as inclined surfaces and sliding plates. When high-temperature steam is used to strip solid impurities, the rotating drum is correspondingly tilted and rotated, thereby improving the flow stability and uniformity of the high-temperature steam and ensuring the stripping effect of the high-temperature steam on the solid impurities inside the filter.

[0033] 4. The present application sets a first electric telescopic rod and a second electric telescopic rod and other components to cooperate with each other, and uses clean water to flush solid impurities.

After that, the solid impurities remaining above the filter screen 301 are completely discharged along the solid discharge valve pipe 114, thereby realizing a complete crude benzene impurity treatment process.

[0051] The driving assembly 2 includes a driving shaft 201, which rotates inside the separation chamber 102. The outer surface of the driving shaft 201 is rotatably connected to the axis of the outer shell 101 through a sealed bearing. The top input end of the driving shaft 201 passes through the outer shell 101 and is provided with a coupling 203. The top input end of the coupling 203 is provided with a driving motor 204. The driving motor 204 is started and drives the driving shaft 201 to rotate through the coupling 203. A protective shell 202 is provided above the outer shell 101 and on the outer surface of the driving shaft 201. The protective shell 202 not only supports and protects the internal driving shaft 201, but also can fix the coupling 203 and the top driving motor 204. The inner wall of the protective shell 202 is provided with a fixed bearing 205. The inner wall of the fixed bearing 205 is connected to The outer surface of the driving shaft 201 is rotatably connected, and the setting of the fixed bearing 205 further improves the rotation stability and efficiency of the driving shaft 201 inside the protective shell 202. The bottom outer surface of the driving shaft 201 is provided with a bottom bearing seat 206.

[0052] The filter assembly 3 includes a filter screen 301, which moves inside the separation chamber 102 to improve the separation effect of impurities in the crude benzene. A plurality of wedge-shaped baffles 307 are evenly arranged at the bottom of the filter screen 301. When the bottom of the wedge-shaped baffle 307 is subjected to an extrusion force, the wedge-shaped baffle 307 correspondingly drives the filter screen 301 to elastically vibrate inside the separation chamber 102. A plurality of filter holes 302 are evenly arranged inside the filter screen 301. The filter holes 302 filter and separate impurities in the crude benzene. An elastic sealing ring 304 is arranged on the outer surface of the filter screen 301. The outer surface of the elastic sealing ring 304 It is in elastic sealing contact with the inner wall of the separation chamber 102. The setting of the elastic sealing ring 304 ensures that no matter what shape the filter screen 301 is elastically deformed into, the elastic sealing ring 304 always ensures sealing contact with the inner wall of the separation chamber 102, thereby preventing the crude benzene impurities from detaching along the elastic sealing ring 304 and the inner wall of the separation chamber 102 and reducing the impurity separation effect. A sealing hole 303 is provided at the axis of the filter screen 301. The inner wall of the sealing hole 303 is sealingly and movably connected with the outer surface of the driving shaft 201. The driving shaft 201 rotates inside the sealing hole 303 and ensures the sealing performance of the filter screen 301.

[0053] The inner wall of the separation chamber 102 is evenly provided with a plurality of fixed blocks 306, and a connecting spring 305 is provided on the top of the fixed block 306. The top of the connecting spring 305 is fixedly connected to the bottom of the elastic sealing ring 304, and the position of the fixed block 306 will not change. The setting of the connecting spring 305 further improves the elastic reset performance of the elastic sealing ring 304. Therefore, when the bottom of the elastic sealing ring 304 is subjected to an upward supporting force, the elastic sealing ring 304 stretches the connecting spring 305 and moves upward. The inside of the wedge-shaped baffle 307 is evenly provided with a plurality of docking holes 308, and the docking holes 308 match the filter holes 302. Therefore, the oil phase or clean water in the crude benzene can flow along the docking holes 308 and the filter holes 302.

[0054] The vibration assembly 4 includes a rotating cylinder 401, and the rotation of the rotating cylinder 401 rotates with the rotation of the driving shaft 201. A plurality of first electric telescopic rods 410 are evenly arranged above the outer surface of the driving shaft 201, and a plurality of second electric telescopic rods 411 are evenly arranged below the outer surface of the driving shaft 201. The first electric telescopic rods 410 and the second electric telescopic rods 411 match each other and are both located inside the separation chamber 102. Therefore, when the output ends of the first electric telescopic rods 410 and the second electric telescopic rods 411 are extended, the rotating cylinder 401 is correspondingly driven. Moving away from the end of the driving shaft 201, the output ends of the first electric telescopic rod 410 and the second electric telescopic rod 411 close to the rotating cylinder 401 are both provided with a hinge seat 412, and the other end of the hinge seat 412 is hinged to the side wall of the rotating cylinder 401. The first electric telescopic rod 410 and the second electric telescopic rod 411 are hinged to the rotating cylinder 401 by means of the hinge seat 412. When the extension distances of the output ends of the first electric telescopic rod 410 and the second electric telescopic rod 411 are different, the corresponding rotating cylinder 401 tilts and rotates.

[0055] A through hole 402 is provided inside the rotating cylinder 401, and a top groove 404 is opened on the top of the rotating cylinder 401. The top groove 404 is internally sealed and slidably connected with a sliding plate 407, and the sliding plate 407 can slide up and down inside the top groove 404. A plurality of matching holes 408 are evenly provided inside the sliding plate 407, and the through hole 402 matches the matching hole 408. When the overlapping area between the matching hole 408 and the through hole 402 increases, the amount of clean water passing between the matching hole 408 and the through hole 402 increases accordingly, thereby increasing the turbulent effect of the clean water inside the separation chamber 102, thereby further improving the cleaning effect of the impurities inside the filter 301.

[0056] The two side walls of the rotating cylinder 401 are symmetrically provided with inclined surfaces 403, which match the rotation direction of the driving shaft 201. The setting of the inclined surfaces 403 further realizes the stability of the upward flow of clean water inside the separation chamber 102, and cooperates with the driving shaft 201 to drive the rotation of the rotating cylinder 401, thereby improving the cleaning effect of the clean water on the solid impurities inside the filter 301.

[0057] A pressure sensor 405 is provided at the bottom of the sliding plate 407, and a return spring 406 is provided at the inner bottom of the top groove 404. The top of the return spring 406 is fixedly connected to the bottom of the pressure sensor 405. The pressure sensor 405 is used to detect the pressure value of the sliding plate 407. An arc-shaped top head 409 is provided at the top of the sliding plate 407. The top of the arc-shaped top head 409 matches the bottom outer surface of the wedge-shaped baffle 307. As the rotating cylinder 401 rotates, the arc-shaped top head 409 continuously squeezes and collides with the wedge-shaped baffle 307, thereby realizing vibration cleaning of the filter 301. The height value of the wedge-shaped baffle 307 gradually decreases from one end of the driving shaft 201 to the other end. With the help of the different contact positions between the wedge-shaped baffle 307 and the arc-shaped top head 409 on the top of the sliding plate 407, the vibration amplitude and the inclination angle of the filter 301 are further adjusted.

[0058] When crude benzene is separated from impurities, the crude benzene flows above the filter 301 and realizes the downward flow of the oil phase. However, since the inlet and outlet directions of the crude benzene are fixed, the crude benzene is easily accumulated on one side above the filter 301, thereby reducing the separation efficiency and affecting the recovery accuracy of the oil phase; at the same time, when the crude benzene is subsequently separated by means of high-temperature steam, since the air inlet direction of the steam is fixed and the flow direction of the steam in the separation chamber 102 is unstable, the high-temperature separation efficiency of the high-temperature steam on the impurities inside the filter 301 is uneven, thereby reducing the separation effect of the oil phase in the impurities; when the impurities are cleaned with clean water afterwards, since the rotation direction of the drive shaft 201 is fixed, the clean water is easily rotated tangentially inside the separation chamber 102 and forms a swirling phenomenon, which will reduce the cleaning effect of the impurities inside the filter 301 and easily cause pollution to the subsequent impurity separation of the crude benzene.

[0059] In order to solve the above problems, when the crude benzene fixed impurity separation and processing system is actually used, the controller 103 controls the opening of the feed valve pipe 107 and the discharge valve pipe 108 of the first shell 101 (the other valve pipes connected to the crude benzene fixed impurity separation and processing system are in a closed state), and the crude benzene passes through the separation chamber 102, and the solid impurities are intercepted and adsorbed on the filter 301. This step monitors the pressure difference before and after the first shell 101, and controls the pressure difference between the feed valve pipe 107 and the discharge valve pipe 108 to be ≤0.2MPa. When the pressure difference reaches the set value, this drainage operation step is based on the first contact liquid level switch and the second contact liquid level switch in the separation chamber 102. Within the set time (30 minutes), the first contact liquid level switch and the second contact liquid level switch drop to "zero", which is regarded as the end of the drainage stage.

[0060] Afterwards, the controller 103 controls the closing of the feed valve pipe 107 and the discharge valve pipe 108 of the first shell 101, which is regarded as the end of the filtration stage; the controller 103 controls the opening of the feed valve pipe 107 and the discharge valve pipe 108 of the second bypass online equipment (the other valve pipes connected to the crude benzene fixed impurity separation and treatment system are in a closed state), and the raw crude benzene filtration is switched to the second shell 101 for filtration, thereby realizing a batch processing procedure, improving the separation and treatment efficiency, and ensuring the separation and treatment effect.

[0061] After the switching filtration is normal, the controller 103 controls the closing of the feed valve tube 107 and the discharge valve tube 108 of the first shell 101 to drain the crude benzene liquid in the separation chamber 102. The controller 103 controls the opening of the gas phase communication valve tube 109 and the oil phase discharge valve tube 110. The shell 101 introduces gas along the gas phase communication valve tube 109 to empty the oil phase in the separation chamber 102 into the organic tank for recovery, thereby separating the solid impurities from the crude benzene oil phase and recovering the organic matter therein. When the recovery of the oil phase is completed, the controller 103 controls the closing of the oil phase discharge valve tube 110.

[0062] In this process, since the crude benzene enters the separation chamber 102 along the feed valve tube 107 and accumulates above the filter 301, the controller 103 controls the drive motor 204 to start, and the bottom output end of the drive motor 204 drives the drive shaft 201 to rotate forward through the coupling 203, and the drive shaft 201 drives multiple first electric telescopic rods 410 and second electric telescopic rods 411 to rotate forward. In the initial state, the first electric telescopic rod 410 and the second electric telescopic rod 411 are at an initial length, and the rotating cylinder 401 is in an initial position. The first electric telescopic rod 410 and the second electric telescopic rod 411 drive the rotating cylinder 401 at the output end to rotate forward. At this time, with the help of the downward feeding direction of the rotating cylinder 401, the downward circulation efficiency of the oil phase is further improved, and the recovery accuracy and recovery efficiency of the oil phase are guaranteed.

[0063] The rotating cylinder 401 rotates and drives the sliding plate 407 inside the top groove 404 to rotate forward. When the arc-shaped top head 409 on the top of the sliding plate 407 squeezes and collides with the bottom of the wedge-shaped baffle 307, the wedge-shaped baffle 307 drives the filter 301 to move upward in the separation chamber 102. The filter 301 drives the elastic sealing ring 304 to stretch the connecting spring 305 to move upward. When the arc-shaped top head 409 on the top of the sliding plate 407 is separated from the bottom of the wedge-shaped baffle 307, the elastic sealing ring is driven by the elastic force of the connecting spring 305. 304 moves downward to return to its original position, and the elastic sealing ring 304 simultaneously drives the filter screen 301 to move downward to return to its original position, thereby realizing the up and down vibration of the filter screen 301 inside the separation chamber 102, thereby improving the vibration cleaning effect of the crude benzene above the filter screen 301, and ensuring that the oil phase can flow downward along the filter holes 302 between the filter screens 301 for recovery. At the same time, the up and down vibration of the filter screen 301 can also vibrate and clear the solid impurities blocked in the filter holes 302, thereby preventing them from blocking the filter holes 302 for a long time and reducing the flow efficiency of the oil phase.

[0064] When the wedge-shaped baffle plate 307 and the arc-shaped top head 409 on the top of the sliding plate 407 are squeezed and contacted with each other, the sliding plate 407 is driven downward to squeeze the return spring 406 under the action of the action force and the reaction force, and the pressure value detected by the pressure sensor 405 reaches the set pressure preset value. When the pressure value detected by the pressure sensor 405 increases and is greater than the set pressure preset value, it indicates that crude benzene is accumulated above the filter screen 301 at this position, and the controller 103 controls the output ends of the first electric telescopic rod 410 and the second electric telescopic rod 411 to shorten, and the first electric telescopic rod 410 and the second electric telescopic rod 411 drive the rotating cylinder 401 to move toward the end close to the driving shaft 201, and the rotating cylinder 401 drives the sliding plate 407 to move simultaneously. The wedge-shaped baffle 307 moves step by step. As the height of the wedge-shaped baffle 307 increases when it is close to the end of the driving shaft 201, when the arc-shaped top 409 on the top of the sliding plate 407 and the wedge-shaped baffle 307 are squeezed and contacted with each other, the upward movement value of the wedge-shaped baffle 307 increases, and the wedge-shaped baffle 307 drives the filter screen 301 to move upward. The distance increased, after that, when the arc-shaped top 409 on the top of the sliding plate 407 is separated from the wedge-shaped baffle 307, the first electric telescopic rod 410 and the second electric telescopic rod 411 drive the rotating cylinder 401 to return to its original position, and the filter screen 301 moves downward to return to its original position, and the up and down vibration amplitude of the filter screen 301 inside the separation chamber 102 increases, thereby further improving the vibration clearing effect on the filter screen 301, and ensuring that the oil phase in the crude benzene is evenly and thoroughly circulated and recovered downward.

[0065] After the oil discharge stage inside the separation chamber 102 is completed, the crude benzene inside the separation chamber 102 is steam-heated to separate the crude benzene oil phase adsorbed on the solid impurities. At this time, the controller 103 controls the steam addition valve pipe 111 to open, and the high-temperature steam directly enters the equipment along the steam addition valve pipe 111, so that the organic matter is separated from the solid impurities in the form of steam in the form of steam stripping.

[0066] This operation step is based on the display of the thermometer in the separation chamber 102. Within 3 minutes after the steam is introduced, the thermometer displays ≥100°C, which is considered to be normal in the addition of steam. When the above conditions are met, the steam replacement is carried out for 30 minutes, which is considered to be the end of the replacement stage. The controller 103 controls the closure of the steam addition valve pipe 111, and the generated process steam enters the crude benzene hydrogenation unit through the gas phase communication valve pipe 109.

[0067] At the same time, since the position where steam is added to the valve tube 111 is fixed and the steam flow direction inside the separation chamber 102 is uneven, the steam cannot perform high-temperature stripping of the solid impurities inside the filter 301. At this time, the controller 103 controls the drive motor 204 to reverse, and the drive motor 204 drives the drive shaft 201 to reverse through the coupling 203. The drive shaft 201 drives the rotating cylinder 401 to rotate in the opposite direction through multiple first electric telescopic rods 410 and second electric telescopic rods 411. The inclined surface 403 of the side wall of the rotating cylinder 401 pushes the steam inside the separation chamber 102 and reaches the inside of the filter 301, thereby improving the steam stripping effect on the solid impurities inside the filter 301.

[0068] At the same time, in order to ensure that the high-temperature steam entering the separation chamber 102 along the steam addition valve tube 111 can flow evenly, the controller 103 controls the second electric telescopic rod 411 to be in the initial position, so that the bottom of the rotating cylinder 401 matches the position of the steam addition valve tube 111, that is, the distance between the bottom of the rotating cylinder 401 and the driving shaft 201 is the same as the distance between the steam addition valve tube 111 and the driving shaft 201. The high-temperature steam inside the steam addition valve tube 111 enters the separation chamber 102 and can flow continuously upward along the inclined surface 403 under the pushing action of the rotating cylinder 401, thereby improving the pushing and stripping effect on the steam inside the separation chamber 102.

[0069] Afterwards, the controller 103 controls the length of the first electric telescopic rod 410 to change continuously, and the first electric telescopic rod 410 drives the upper position of the rotating cylinder 401 to change continuously through the hinge seat 412. Then, the steam on the inclined surface 403 of the side wall of the rotating cylinder 401 continuously reaches the bottom of the filter 301 under the pushing action of the reverse rotation of the rotating cylinder 401, and with the help of the uniform change in the top position of the rotating cylinder 401, the high-temperature steam evenly reaches the inside of the filter 301 and performs high-temperature stripping on the solid impurities, further improving the contact uniformity and thoroughness of the solid impurities in the steam filter 301, and ensuring the steam stripping effect.

[0070] At the same time, when the rotating cylinder 401 rotates, the sliding plate 407 is synchronously driven to rotate, and the arc-shaped top head 409 on the top of the sliding plate 407 and the wedge-shaped baffle 307 squeeze and collide with each other. The pressure value detected by the pressure sensor 405 is at the initial value, and as the first electric telescopic rod 410 drives the rotating cylinder 401 to change its rotation position, the pressure value detected by the pressure sensor 405 changes accordingly. However, when the pressure value detected by the pressure sensor 405 at a certain position is greater than the corresponding pressure preset value set at the position, it means that the solid impurities docked by the filter screen 301 at the position increase, and the controller 103 controls the output end of the first electric telescopic rod 410 not to move, and the top of the rotating cylinder 401 does not move at this position. At this time, high-temperature steam continuously performs high-temperature stripping on this position along the inclined surface 403 of the side wall of the rotating cylinder 401, thereby further improving the stripping effect of solid impurities at the accumulation position, with higher accuracy and stronger adaptability. At the same time, the collision between the arc-shaped top head 409 at the top of the sliding plate 407 and the wedge-shaped baffle 307 further increases the vibration frequency of the filter screen 301, thereby improving the vibration filtering and dredging effect of the solid impurities inside the filter hole 302, with stronger dredging performance and better controllability.

[0071] When the stripping stage inside the separation chamber 102 is completed, the controller 103 controls the steam to be added to the valve tube 111 tank body, and the controller 103 controls to open the water adding valve tube 112, and clean water is added to the separation chamber 102 along the water adding valve tube 112. When the liquid level contact switch in the separation chamber 102 is triggered to display "full", it is full of water, and the controller 103 controls to close the water adding valve tube 112, and turns on the drive motor 204. The drive motor 204 drives the drive shaft 201 to reverse through the coupling 203, and the drive shaft 201 drives The first electric telescopic rods 410 and the second electric telescopic rods 411 on the side of the moving cylinder drive the rotating cylinder 401 to reverse, and with the help of the inclined surface 403 of the side wall of the rotating cylinder 401, the clean water continuously exerts impact force on the solid impurities adsorbed on the separation chamber 102 and the filter 301, so that the solid impurities are desorbed and enter the water phase. Due to the replacement of the oil phase, the solid impurities are no longer wrapped by organic matter and lose their sticky appearance, and are very easy to desorb into the water phase. Stirring for 30 minutes is considered to be the end of desorption.

[0072] At the same time, the controller 103 controls the output ends of multiple first electric telescopic rods 410 and second electric telescopic rods 411 at the same position to extend at different distances, so that the distances between the multiple rotating cylinders 401 and the driving shaft 201 are different. When the driving shaft 201 rotates, the rotating cylinder 401 is driven to rotate by the multiple first electric telescopic rods 410 and the second electric telescopic rods 411. The stirring force applied by the rotating cylinder 401 to the clean water inside the separation chamber 102 is different, thereby ensuring the cleaning effect of the clean water on the solid impurities inside the filter 301, and at the same time, the clean water can also flow along the overlapping position of the through hole 402 and the matching hole 408, so that the clean water can be stirred axially while being cut horizontally, thereby ensuring the irregular stirring of the clean water, and avoiding the clean water swirling inside the separation chamber 102 for a long time and affecting the cleaning effect on the solid impurities inside the filter 301.

[0073] At the same time, when the rotating cylinder 401 rotates to the end close to the solid discharge valve tube 114, the controller 103 controls the output ends of the multiple first electric telescopic rods 410 and the second electric telescopic rods 411 to extend, and the first electric telescopic rod 410 and the second electric telescopic rod 411 drive the rotating cylinder 401 to move away from the end of the driving shaft 201, and the rotating cylinder 401 drives the sliding plate 407 inside the top groove 404 to move, and the arc-shaped top head 409 on the top of the sliding plate 407 is reduced in height when it is squeezed and contacted with the wedge-shaped baffle 307, and the wedge-shaped baffle 307 drives the filter screen 301 to reduce its height at the end of the solid discharge valve tube 114, and the end of the filter screen 301 matches the input port of the solid discharge valve tube 114. At the same time, when the rotating cylinder 401 rotates to the end away from the solid discharge valve tube 114, the controller 103 controls the output ends of the first electric telescopic rod 410 and the second electric telescopic rod 411 to shorten, and the first electric The movable telescopic rod 410 and the second electric telescopic rod 411 drive the rotating cylinder 401 to move toward the end of the driving shaft 201, and the rotating cylinder 401 drives the sliding plate 407 inside the top groove 404 to move toward the end of the driving shaft 201. When the arc-shaped top head 409 on the top of the sliding plate 407 is squeezed and contacted with the bottom of the wedge-shaped baffle 307, the upward movement distance of the wedge-shaped baffle 307 increases, and the wedge-shaped baffle 307 drives the filter screen 301 to move upward. The filter screen 301 tilts inside the separation chamber 102 and tilts obliquely downward toward the end of the solid discharge valve pipe 114. With the help of the tilting effect and the continuous vibration of the filter screen 301, the solid impurities above the filter screen 301 continue to flow obliquely downward and reach the inside of the solid discharge valve pipe 114 for recovery and treatment, thereby improving the recovery efficiency and recovery effect of the solid impurities and preventing the solid impurities above the filter screen 301 from affecting the subsequent separation and treatment of crude benzene.

[0074] At the same time, when the rotating cylinder 401 drives the sliding plate 407 inside the top groove 404 to rotate and squeeze and contact each other with the wedge-shaped baffle 307, if the pressure value detected by the pressure sensor 405 increases and is greater than the preset pressure value set at this position, it means that solid impurities are accumulated above the filter screen 301 at this position, and the controller 103 controls the output ends of the first electric telescopic rod 410 and the second electric telescopic rod 411 to shorten, and the first electric telescopic rod 410 and the second electric telescopic rod 411 drive the rotating cylinder 401 to move closer to the end of the drive shaft 201, and the rotating cylinder 401 drives The sliding plate 407 inside the moving top groove 404 moves synchronously. When the arc-shaped top head 409 on the top of the sliding plate 407 is squeezed and contacted with the bottom of the wedge-shaped baffle 307, the wedge-shaped baffle 307 drives the filter 301 to move upward to increase the distance. Then, when the arc-shaped top head 409 on the top of the sliding plate 407 is separated from the bottom of the wedge-shaped baffle 307, the wedge-shaped baffle 307 drives the filter 301 to move downward to return to its original position. Then, the up and down vibration amplitude of the filter 301 inside the separation chamber 102 is increased, thereby further improving the vibration cleaning effect of the filter 301, and the cleaning efficiency is higher and the cleaning effect is better.

[0075] In addition, since the distance between the rotating cylinder 401 and the driving shaft 201 is different at different positions, the distance between the sliding plate 407 inside the top groove 404 driven by the rotating cylinder 401 and the driving shaft 201 is different, and the sliding plate 407 and the bottom of the wedge-shaped baffle 307 are pressed and contacted at different positions. When the distance between the rotating cylinder 401 and the driving shaft 201 is smaller, the height value of the wedge-shaped baffle 307 is larger, and the sliding plate 407 and the bottom of the wedge-shaped baffle 307 are pressed and contacted with each other. After the sliding plate 407 and the reset spring 406 are pressed and contacted with each other, the distance moved downward along the top groove 404 is larger, and the sliding plate 407 drives the multiple matching holes 408 to move downward. The matching holes 408 and the through holes are pressed and contacted. The larger the overlapping area of ​​402 is, the greater the amount of liquid in the separation chamber 102 that passes through the overlapping position of the matching hole 408 and the through hole 402 in coordination with the rotation of the rotating cylinder 401, which corresponds to an increase in the cutting amount of the clean water in the separation chamber 102 in the lateral direction. After that, when the arc-shaped top head 409 on the top of the sliding plate 407 is separated from the bottom of the wedge-shaped baffle 307, the sliding plate 407 is driven to move upward and return to its original position under the elastic force of the reset spring 406, and the overlapping area of ​​the through hole 402 and the matching hole 408 is continuously reduced to the initial value, thereby ensuring the variability and agitation of the clean water in the separation chamber 102, and achieving a continuous turbulent cleaning effect of the clean water.

[0076] After the replacement stage of the separation chamber 102 is completed, the water phase containing solid impurities is removed from the system in the form of clean water to remove waste water liquid. There are two states: the controller 103 controls to open the liquid discharge valve pipe 113, and the clean water in the separation chamber 102 is discharged. The clean water goes to the waste water tank. When the liquid level contact switch in the equipment is not triggered and displays "zero", the controller 103 controls to close the liquid discharge valve pipe 113; open the water adding valve pipe 112, fill the separation chamber 102 with water, repeat the filling of water, stirring and desorption, and then drain the waste liquid, implement "three full and three empty", use water to bring out the solid impurities above the filter 301, and the controller 103 controls to close the liquid discharge valve pipe 113.

[0077] The controller 103 controls to open the water adding valve pipe 112, fills the separation chamber 102 with water, opens the solid discharge valve pipe 114, and while the water is entering, the solid impurities from the inner side of the filter 301 are discharged to the wastewater tank along the solid discharge valve pipe 114. After running for 30 minutes, the water entering is about 3 to 5 times the volume of the separation chamber 102 according to the flow meter on the water pipeline. Then the controller 103 controls to close the water adding valve pipe 112, close the solid discharge valve pipe 114, and open the liquid discharge valve pipe 113 to discharge the clean water in the separation chamber 102 until the liquid level contact switch is not triggered and displays "zero". The controller 103 controls to close the liquid discharge valve pipe 113, and the clean water discharge stage in the filter 301 is considered to be over.

[0078] After the clean water discharge stage in the separation chamber 102 is completed, the controller 103 controls the closing of the gas phase connecting valve pipe 109 and the opening of the nitrogen pressure test valve pipe 115, and the separation chamber 102 is nitrogen-pressurized to display 0.2MPaG. The controller 103 controls the closing of the nitrogen pressure test valve pipe 115, and the pressure is maintained for 30 minutes. If the pressure decreases by ≤10%, it is considered that the pressure test is qualified. After the pressure test stage is completed, the controller 103 controls the opening of the gas phase connecting valve pipe 109 to relieve the pressure in the separation chamber 102. After the pressure is relieved to normal pressure, the controller 103 controls the closing of the gas phase connecting valve pipe 109.

[0079] After the pressure test stage of separation chamber 102 is completed, the whole process of separation chamber 102 is completed and enters the waiting controller 103 control. After the pressure difference value of the subsequent equipment triggers the switching controller 103 control, the separation chamber 102 enters the next cycle, thereby realizing the cyclic separation and processing process of solid impurities in crude benzene, ensuring the separation and processing quality, and improving the separation and processing efficiency.

[0080] The treatment system effectively improves the separation and treatment effect of crude benzene solid impurities, has stronger circulation, higher separation and treatment efficiency, simple operation, efficient system completion, meets the needs of mass production, and has stronger controllability, higher adjustability, safety and stability; in the process of crude benzene feeding, the rotating drum 401 drives the filter screen 301 to vibrate up and down continuously inside the separation chamber 102, further improving the filtering effect of the oil phase in the crude benzene, avoiding the accumulation of crude benzene and affecting the recovery efficiency of the oil phase; when the high-temperature steam is used to strip the solid impurities, the rotating drum 401 is correspondingly tilted and rotated, thereby improving the flow stability and uniformity of the high-temperature steam, and ensuring the stripping effect of the high-temperature steam on the solid impurities inside the filter screen 301; finally, the solid impurities are flushed with the help of clean water, and the rotation positions of multiple rotating drums 401 are different, which not only realizes the turbulence of clean water inside the separation chamber 102, improves the cleaning effect of the solid impurities inside the filter screen 301, but also drives the filter screen 301 to tilt toward the end of the solid discharge valve pipe 114, thereby improving the recovery efficiency and recovery effect of the solid impurities.

[0081] The processing method of the crude benzene solid impurity separation and processing system as described above comprises the following steps:

[0082] S1. After the crude benzene enters the separation chamber 102 and is filtered by the filter screen 301, the oil phase continuously flows downward for recovery. The rotating cylinder 401 rotates inside the separation chamber 102, and the rotating cylinder 401 drives the sliding plate 407 inside the top groove 404 to rotate. The sliding plate 407 and the bottom of the wedge-shaped baffle 307 are squeezed and contacted with each other and drive the filter screen 301 to vibrate up and down.

[0083] S2. When the pressure value detected by the pressure sensor 405 increases, the rotating cylinder 401 moves toward the end of the driving shaft 201, and the rotating cylinder 401 drives the sliding plate 407 inside the top groove 404 to move and the position of the mutual squeezing contact with the bottom of the wedge-shaped baffle 307 changes, and the wedge-shaped baffle 307 drives the filter 301 to increase the up and down vibration amplitude.

[0084] S3. When high-temperature steam is introduced into the bottom of the separation chamber 102, the bottom position of the rotating cylinder 401 remains unchanged and the top position continuously changes in inclination. The rotating cylinder 401 pushes the high-temperature steam upward and uniformly strips the solid impurities inside the filter screen 301.

[0085] S4. When clean water is introduced into the separation chamber 102, the distances between the multiple rotating cylinders 401 and the end of the driving shaft 201 are different, the filter screen 301 vibrates tiltedly inside the separation chamber 102, the overlapping area of ​​the through hole 402 and the matching hole 408 keeps changing, and the clean water keeps turbulent inside the separation chamber 102.

[0086] By further limiting the processing methods, the processing efficiency can be improved and the processing quality can be guaranteed.
