Embodiment 1
[0033] Refer to attached figure 1 , 2 , a method for recycling waste glue in viscose production, belonging to the field of viscose production, including a method for recycling waste glue with a viscosity of 50 to 70 mPa.s and a method for recycling waste glue with a viscosity less than 50 mPa.s;
[0034] Said viscosity is 50~70mPa.s waste glue recycling method,
[0035] Collect waste glue with a viscosity of 50-70mPa.s. The waste glue comes from the cleaning water of filter cloths, nozzles and components. The temperature of the process environment is controlled at 18-22°C, and then placed in the collection tank I7 to obtain the collected liquid. 1; the collection liquid I in the collection tank 17 is input into the sedimentation type separator 8 again, and the sedimentation type separation machine 8 is 5000r / min operation with the rotating speed, the collection liquid I is separated, and the solid impurities and the collection liquid II are obtained. The solid impurities are...
Embodiment 2
[0042] Compared with Embodiment 1, the difference between this embodiment is that the sedimentation separator 8 separates the collected liquid I at a speed of 6500 r / min.
Embodiment 3
[0044] Compared with Example 1, this embodiment differs in that the filter device III 10 is a filter device III 10 with a filtration precision of 50 μm, and the filter device IV 11 is a filter device IV11 with a filtration precision of 25 μm.
