本发明涉及一种分离聚碳酸酯和溶剂的系统及方法,聚碳酸酯的二氯甲烷溶液和过热蒸汽分别沿混合喷嘴的轴线方向和垂直于混合喷嘴的轴线方向进入混合喷嘴的混合区混合,混合后的物料进入凝结器的器壁上凝结成聚碳酸酯液滴,聚碳酸酯液滴在重力作用下形成聚碳酸酯薄片,聚碳酸酯薄片被吹入聚碳酸酯薄片与溶剂初步分离系统中进行与二氯甲烷溶剂的初步分离;然后,聚碳酸酯薄片进入蒸
The present invention relates to a system and method for separating a polycarbonate and a solvent by mixing a methylene chloride solution and a superheated vapor of polycarbonate into a mixing zone of a mixing nozzle along an axial direction of the mixing nozzle and perpendicular to an axial direction of the mixing nozzle, The mixed material enters the wall of the condenser to condense into polycarbonate droplets, and the polycarbonate droplets form a polycarbonate sheet under the action of gravity. The polycarbonate sheet is blown into the polycarbonate sheet and the preliminary separation system of the solvent A preliminary separation from the methylene chloride solvent is carried out; the polycarbonate flakes then enter the steam
