Tar problem in desolvation vacuum screw pumps

If tar damages the equipment during the solvent recovery process using a vacuum screw pump, it may be due to the presence of substances in the solvent that are prone to pyrolysis at high temperatures, resulting in the formation of tar. Here are some possible solutions and similar cases: 1. Optimize process conditions: It may be necessary to adjust operational parameters such as reducing temperature, lowering pressure, or increasing the liquid circulation speed in order to reduce tar formation. 2. Regular cleaning: Clean the pump regularly to prevent tar from accumulating and causing blockages inside the equipment. 3. Choose materials with good tar resistance: If you frequently encounter tar-related problems, consider using materials with excellent tar resistance to manufacture components such as the pump body and blades. 4. Add barrier devices: Installing filters or other barrier devices at the pump’s inlet can prevent tar from entering the pump. 5. Refer to similar cases: You can consult experts in related industries or other experienced users to find out how they handled similar situations. Please note that in actual operation, the appropriate solution should be selected based on specific circumstances, and safety procedures must be strictly followed throughout the process to ensure the safety of both the equipment and personnel. .
