摘　　要：供热系统双筒式除污器是一种新型除污器。该除污器采用低速沉降原理,利用重力和惯性力的双重作用,有效去除供热系统内的型砂。文中应用计算流体力学软件FLUENT,采用欧拉两相流模型和标准k-ε双方程湍流模型,对双筒式除污器进行了三维的固液两相流的模拟,分析了其内部流场及在不同进口流速下去除型砂的效果。The double cylinder dust-removal device of heating systems is a new-style kind of dust-removal device. The dust-removal device can take out molding sand of heat supply system effectively adopting low-speed sedimentation principle and using double effect of gravity and inertia. It use computational fluid dynamics software FLUENT. And it use Eulerian two-phase flow model and standard κ-ε two-turbulence model for the double cylinder dust-removal device of a solid-liquid flow simulation. It analyses the double cylinder dust-removal device＇s internal flow field and the efficiency of removing sand under different inlet velocity.
