specific Embodiment 1
[0018] The present invention is used for the novel coacervation scrubber that carbon dioxide-propylene oxide copolymer prepares, as figure 1 As shown, a cylindrical kettle body 1 is included, and the kettle body 1 is arranged upright. A central rotating shaft 3 connected to an external motor 2 is longitudinally arranged in the kettle body 1, and several layers of ellipsoidal agitators 4 are vertically arranged side by side at the lower end of the central rotating shaft 3. The ellipsoidal stirrer 4 is surrounded by several hollow elliptical stirring frame leaves 5 arranged staggeredly on the central rotating shaft 3. The inner side wall of the kettle body 1 is provided with a filtering device 6, and the outer wall of the kettle body 1 is corresponding to the filtering device 6. The position is provided with a washing liquid discharge pipe 7.
[0019] In this specific embodiment, the angular distances of adjacent elliptical stirring frame leaves 5 are the same, the horizontal di...
