简介了精馏常识,从精馏常识的前提假设和逆向思维两个方面入手,对精馏中的平衡级模型、理论塔板计算中绝热设定和精馏是为了提高产品纯度3个问题进行拓展思考,并引出非混合池模型、热耦合和混合塔等概念,启示了一些思维拓展的方式。 In this paper, the general knowledge of distillation is introduced. From the two aspects of preconditions and reverse thinking of distillation common sense, three questions about equilibrium model in distillation, adiabatic setting and rectification in theoretical calculation of plate are to improve product purity Expansion of thinking, and leads to non-mixed pool model, coupled with the concept of heat and hybrid towers, inspired some ideas to expand the way.
