| titleOfInvention | Back flushing method of simulated moving bed device for adsorption separation of dimethylbenzene |
| abstract | The application discloses a backwashing method of a simulated moving bed device for adsorbing and separating dimethylbenzene, wherein two adjacent inlet and outlet pipelines of the simulated moving bed device are used as a group of cleaning pipes, wherein the inlet and outlet pipeline positioned at the downstream side of a material path is used as a flushing liquid inlet pipe, and the inlet and outlet pipeline positioned at the upstream side of the material path is used as a flushing liquid outlet pipe; the back washing liquid enters the connected grating from the washing liquid inlet pipe and flows upwards, and is discharged from the washing liquid outlet pipe after the bed layer positioned at the upper side of the washing liquid inlet pipe is back washed; the backwash liquid does not pass through the rotary valve. Utilize this application can only carry out the back flush to single bed, can not lead to the fact the influence to adsorbent and the internals of other beds, because the backwash liquid does not pass through the rotary valve, has avoided the interference of rotary valve work, has guaranteed the overall stability of production. |
