How does the vacuum system separate viscous substances and bring them into the vacuum unit?
Thread Content
With a negative pressure of 0.1 MPa, the material is cooled to -10 degrees in the vacuum unit; viscous substances precipitate within this unit. How can these substances be separated in order to ensure stable operation of the vacuum unit?
A buffer tank is placed in front, where crystallization occurs. Two can be connected in parallel for alternating use.
Install a separation tower; it should be effective
Ensure proper pre-filtering, and select the vacuum pump correctly
There are 2 options available: 1. Add a condensing coil in front of the vacuum unit’s inlet; the cooled liquid flows directly into the liquid collection tank, while the upper end remains connected to the unit’s suction port. 2. When preparing to shut down, after closing the main valve on the steam inlet pipeline, the vacuum unit opens the purge steam inlet valve for about 5 minutes before shutting down automatically (this allows most of the material inside the unit to be discharged).
