摘要
卧式捏合反应器具有大的反应体积,优异的混合性能、表面更新性能、传热性能和自清洁性能,因而在本体聚合、缩合聚合和聚合物脱挥等领域具有广阔的应用前景.综述了几种捏合反应器及其搅拌特性研究,以及在聚合工业中的应用研究,指出捏合反应器具有非常复杂的几何结构,实验测量技术具有很大的局限性,计算流体力学(CFD)模拟为主要的研究方法;进一步指出具有自清洁特性的捏合反应器是聚合物搅拌设备开发的主要方向,高效、集约化、绿色、环保的先进工艺与装置是促进我国聚合工业发展的关键.
Abstract
The horizontal kneading reactor with large effective reaction volume possesses excellent mixing,surface renewal,heat transfer and self-cleaning performance.Hence,the kneading reactor has broad application prospects in fields such as bulk polymerization,polymerization condensation and polymer devolatilization.This article reviews several types of kneading reactors,research on stirring characteristics and their application in the polymerization industry.The experimental measurement techniques have significant limitations due to the complex geometry and the CFD simulation is the main research method.The kneading reactor with self-cleaning characteristics is the main direction for the development of agitated equipment for polymer.The efficient,intensive,green and environmentally friendly advanced processes and devices are the key to promoting the development of polymer industry.
