Embodiment 1
[0024] (1) In the stage of water suspension coating granulation and vacuum distillation, the granulation kettle 1 circulation hot water unit and the winding tube condenser 2, 3 circulation chiller units are opened in advance, and the condenser is pre-cooled to 8°C. In the process of gradually heating up, open the vacuum port valve of the secondary solvent receiving tank 5, and the solvent vapor will basically realize complete condensation after passing through the primary and secondary winding tube condensers 2 and 3 and the primary and secondary solvent receiving tanks 4 and 5 in sequence. The final aqueous solvent is received into the primary and secondary solvent receiving tanks.
[0025] (2) Dehydration and purification of the solvent obtained by condensation: first, the solvent recovered by the solvent receiving tanks 4 and 5 is allowed to stand still for a period of time to form obvious layers, and the liquid outlet bypass valve at the bottom of the primary and secondary ...
Embodiment 2
[0028] (1) In the stage of water suspension coating granulation and vacuum distillation, the granulation kettle 1 circulation hot water unit and the winding tube condenser 2, 3 circulation chiller units are opened in advance, and the condenser is pre-cooled to 5°C. In the process of gradually heating up, open the vacuum port valve of the secondary solvent receiving tank 5, and the solvent vapor will basically realize complete condensation after passing through the primary and secondary winding tube condensers 2 and 3 and the primary and secondary solvent receiving tanks 4 and 5 in sequence. The final aqueous solvent is received into the primary and secondary solvent receiving tanks.
[0029] (2) Dehydration and purification of the solvent obtained by condensation: first, the solvent recovered by the solvent receiving tanks 4 and 5 is allowed to stand still for a period of time to form obvious layers, and the liquid outlet bypass valve at the bottom of the primary and secondary ...
Embodiment 3
[0032] (1) In the stage of water suspension coating granulation and vacuum distillation, the granulation kettle 1 circulation hot water unit and the winding tube condenser 2, 3 circulation chiller units are opened in advance, and the condenser is pre-cooled to 3°C. In the process of gradually heating up, open the vacuum port valve of the secondary solvent receiving tank 5, and the solvent vapor will basically realize complete condensation after passing through the primary and secondary winding tube condensers 2 and 3 and the primary and secondary solvent receiving tanks 4 and 5 in sequence. The final aqueous solvent is received into the primary and secondary solvent receiving tanks.
[0033](2) Dehydration and purification of the solvent obtained by condensation: first, the solvent recovered by the solvent receiving tanks 4 and 5 is allowed to stand still for a period of time to form obvious layers, and the liquid outlet bypass valve at the bottom of the primary and secondary s...
