Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0032] Such as figure 1 As shown, a water washing system for solvent-based regenerated cellulose membranes includes several washing tanks 4 connected in sequence. Adjacent washing tanks 4 are connected by overflow structures, and the overflow directions between the washing tanks are the same. A cellulose film conveying device is arranged inside, and the conveying direction of the cellulose film is opposite to the overflow direction between the washing tanks; the outlet of each washing tank 4 is equipped with a scraper 2 and a spraying device.
[0033] The overflow structure can be an overflow weir or an overflow pipe 6. When the overflow structure is an overflow weir, the overflow weir is set at the set height of the side wall of the washing tank 4. When the liquid level in the washing tank When the set height is reached, clear water flows int...
