When the crude benzene is separated from impurities, the crude benzene flows above the filter screen 301 and downwards flows to realize the downward flow of the oil phase, but because the liquid inlet direction and the liquid outlet direction of the crude benzene are fixed, the crude benzene is easy to accumulate at one side above the filter screen 301, the separation efficiency is reduced, the recovery precision of the oil phase is affected, meanwhile, when the crude benzene is separated by means of high-temperature steam, the high-temperature steam has unbalanced high-temperature separation efficiency on impurities in the filter screen 301 because of the fixed air inlet direction of the steam and unstable flow direction of the steam in the separating cavity 102, the separation effect of the oil phase in the impurities is reduced, and then when the impurities are cleaned by clean water, the clean water is easy to tangentially rotate in the separating cavity 102 because of the fixed rotation direction of the driving shaft 201, the cleaning effect on the impurities in the filter screen 301 is reduced, and the pollution is easy to be caused on the subsequent impurity separation of the crude benzene.
In order to solve the above problems, when the crude benzene fixed impurity separation processing system is in actual use, the controller 103 controls to open the feed valve pipe 107 and the discharge valve pipe 108 of the first housing 101 (other valve pipes communicating the crude benzene fixed impurity separation processing system are all in a closed state), crude benzene is adsorbed on the filter screen 301 through the separation chamber 102, solid impurities are intercepted, the step monitors the pressure difference between the front and rear of the first housing 101, controls the pressure difference between the feed valve pipe 107 and the discharge valve pipe 108 to be less than or equal to 0.2MPa, and when the pressure difference reaches a set value, the liquid discharging operation step is regarded as ending in a liquid discharging stage according to the fact that the first contact liquid level switch and the second contact liquid level switch in the separation chamber 102 are reduced to zero within a set time (30 minutes).
And the controller 103 controls the feed valve pipe 107 and the discharge valve pipe 108 of the first shell 101 to be closed and is regarded as the end of the filtering stage, and the controller 103 controls the feed valve pipe 107 and the discharge valve pipe 108 of the bypass on-line second equipment to be opened (other valve pipes communicated with the crude benzene fixed impurity separation treatment system are all in a closed state), so that the raw material crude benzene is filtered and switched to the second shell 101 for filtering, thereby realizing a batch treatment process, improving the separation treatment efficiency and ensuring the separation treatment effect.
After the switching filtration is normal, the controller 103 controls to close the feed valve pipe 107 and the discharge valve pipe 108 of the first shell 101, the crude benzene liquid in the separation cavity 102 is discharged completely, the controller 103 controls to open the gas phase communication valve pipe 109 and the oil phase discharge valve pipe 110, the shell 101 introduces gas along the gas phase communication valve pipe 109, the oil phase in the separation cavity 102 is emptied and enters the organic tank for recovery, so that solid impurities are separated from the crude benzene oil phase, organic matters in the crude benzene oil phase are recovered, and after the recovery of the oil phase is completed, the controller 103 controls to close the oil phase discharge valve pipe 110.
In this process, as the crude benzene enters the separating chamber 102 along the feeding valve pipe 107 and is accumulated above the filter screen 301, the controller 103 controls the driving motor 204 to start, the output end at the bottom of the driving motor 204 drives the driving shaft 201 to rotate forward through the coupling 203, the driving shaft 201 drives the first electric telescopic rods 410 and the second electric telescopic rods 411 to rotate forward, the first electric telescopic rods 410 and the second electric telescopic rods 411 are in initial lengths under initial conditions, the rotating cylinder 401 is in initial positions, the first electric telescopic rods 410 and the second electric telescopic rods 411 drive the rotating cylinder 401 at the output end to rotate forward, and at this time, the downward circulation efficiency of oil phase is further improved by means of the downward feeding direction of the rotating cylinder 401, and the recovery precision and recovery efficiency of the oil phase are ensured.
The rotary cylinder 401 rotates and drives the sliding plate 407 in the top groove 404 to rotate positively, when the arc-shaped top 409 at the top of the sliding plate 407 collides with the bottom of the wedge-shaped baffle 307 in an extrusion mode, the wedge-shaped baffle 307 drives the filter screen 301 to move upwards in the separation cavity 102, the filter screen 301 drives the elastic sealing ring 304 to stretch and connect the spring 305 to move upwards, and when the arc-shaped top 409 at the top of the sliding plate 407 is separated from the bottom of the wedge-shaped baffle 307, the elastic sealing ring 304 is driven to move downwards under the action of the elasticity of the connecting spring 305 to restore the original position, the elastic sealing ring 304 synchronously drives the filter screen 301 to move downwards to restore the original position, and further, the filter screen 301 vibrates upwards and downwards in the separation cavity 102, the vibration cleaning effect on crude benzene above the filter screen 301 is improved, oil phases can flow downwards along the filter holes 302 between the filter screens 301 to be recovered, meanwhile, the vertical vibration of the filter screen 301 can also clean solid impurities blocked in the filter holes 302 in a vibration mode, the filter holes 302 are prevented from being blocked for a long time, and the flow efficiency of the oil phase is reduced.
When the pressure value detected by the pressure sensor 405 reaches the preset pressure value, and when the pressure value detected by the pressure sensor 405 increases and is greater than the preset pressure value, it is indicated that the crude benzene above the filter screen 301 at the position is accumulated, the controller 103 controls the output ends of the first electric telescopic rod 410 and the second electric telescopic rod 411 to be shortened, the first electric telescopic rod 410 and the second electric telescopic rod 411 drive the rotary cylinder 401 to move towards the end close to the driving shaft 201, the rotary cylinder 401 drives the rotary plate 407 to synchronously move, and as the height of the wedge-shaped baffle 307 near the end of the driving shaft 201 increases, the arc-shaped top 409 at the top of the sliding plate 407 is in mutual extrusion contact with the wedge-shaped baffle 307, the upward movement value of the wedge-shaped baffle 307 increases, the upward movement distance of the filter screen 301 is increased, and then after the arc-shaped top 409 at 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 rotary cylinder 401 to move towards the end close to the driving shaft 201, the vibration of the filter screen 301 is recovered, and the vibration amplitude of the filter screen 301 is further increased, and the vibration in situ is recovered.
After the oil phase exhausting stage in the separation chamber 102 is finished, the crude benzene in the separation chamber 102 is heated by steam, so that the crude benzene oil phase adsorbed on the solid impurities is separated, at this time, the controller 103 controls the steam adding valve tube 111 to open, high-temperature steam directly enters the equipment along the steam adding valve tube 111, and organic matters are separated from the solid impurities in a steam stripping mode.
This operation step is based on the fact that the thermometer in the separation chamber 102 shows that the temperature is not less than 100 ℃ within 3 minutes after the steam is introduced, and the steam is normally added, and when the above conditions are satisfied, the steam is replaced for 30 minutes, and the replacement stage is completed, and the controller 103 controls the closing of the steam adding valve tube 111, so that the generated process steam enters the crude benzene hydrogenation unit through the vapor phase communicating valve tube 109.
Meanwhile, as the position of the steam adding valve tube 111 is fixed and the flow direction of the steam in the separation cavity 102 is uneven, the steam cannot strip the solid impurities in the filter screen 301 at high temperature, at this time, the controller 103 controls the driving motor 204 to rotate reversely, the driving motor 204 drives the driving shaft 201 to rotate reversely through the coupler 203, the driving shaft 201 drives the rotating cylinder 401 to rotate reversely through the plurality of first electric telescopic rods 410 and the second electric telescopic rods 411, and the inclined plane 403 on the side wall of the rotating cylinder 401 pushes the steam in the separation cavity 102 and reaches the inside of the filter screen 301, so that the stripping effect of the steam on the solid impurities in the filter screen 301 is improved.
Meanwhile, in order to ensure that high-temperature steam entering the separation cavity 102 along the steam adding valve tube 111 can flow uniformly, the controller 103 controls the second electric telescopic rod 411 to be in an initial position, the bottom of the rotating cylinder 401 is matched with the position of the steam adding valve tube 111, namely, the distance between the bottom of the rotating cylinder 401 and the driving shaft 201 is the same as the distance between the steam adding valve tube 111 and the driving shaft 201, and the high-temperature steam inside the steam adding valve tube 111 enters the separation cavity 102 and can flow upwards continuously along the inclined plane 403 under the pushing action of the rotating cylinder 401, so that the pushing stripping effect of steam inside the separation cavity 102 is improved.
