喷水塔饱和器的动态建模与仿真

讨论了建立喷水塔饱和器的一维动态模型的方法。该方法将饱和器沿高度方向分解为若干段，每个段用气体和水滴模块表示。通过建立显式仿真模型，可以得到饱和器在稳定状态下和动态过程中参数的变化规律。根据模型稳定状态的数据。沿气体的主要流动方向，压力变化基本呈线性关系，而其它参数的变化为非线性。模型动态仿真结果表明，饱和器中气体压力和水之间的相互作用属于快过程，表现出与换热器不同的特点。

Dynamic Modeling and Simulation of a Water-spray Tower Saturator

A method of building a one-dimensional dynamic model for a water-spray tower saturator is discussed. Under this method the saturator has been divided along its height into several segments, each being represented by gas and water-drop modules. The setting-up of an explicit simulation model makes it possible to clarify the variation mechanism of parameters of the saturator under a steady state and during a dynamic process. According to the data of the model under a steady state the variation of pressure along the main flow direction of gas basically assumes a linear relationship, while the variation of other parameters has been found to be nonlinear. The results of the model dynamic simulation indicate that the interaction between gas pressure and water in the saturator features a rapid process, thus exhibiting the characteristics different from those of a heat exchanger.
