玻璃纤维窑炉玻璃液流场数学模拟研究

Mathematical Simulation of Glass Liquid Flow Field in Fiberglass Furnace

玻璃纤维窑炉作为玻璃纤维生产最重要的热工设备之一,被称为玻璃纤维生产的心脏。为了实现玻璃液熔制的高效节能和玻璃液高质量的输出,需掌握窑炉中高温玻璃液的运动轨迹,对生产过程实现实时控制。通过对窑炉内玻璃液的流动状态进行模拟,可以在提高产品质量、节约能源、降低废物排放、提高单位产出率等方面得到优化。以年产8万t玻璃纤维窑炉玻璃液为研究对象,通过使用ANSYS软件对窑炉生产状态进行数值模拟,分析了模型中温度场分布、速度场分布和电功率场分布情况,同时计算了不同电助熔参数设置对窑炉内玻璃液温度场分布以及速度场分布的影响,结合生产实际提出了窑炉内部实际的玻璃液流动场优化情况。

Fiberglass furnace,as one of the most important thermal equipment in fiberglass production,is known as the heart of fiberglass production.In order to achieve high efficiency and energy saving of glass melting and high quality output of glass-melt,it is necessary to master the movement track of high temperature glass-melt in the furnace,and realize real-time control of the production process.By simulating the flow state of glass-melt in the furnace,it can be optimized in improving product quality,saving energy,reducing waste emissions and increasing unit output rate.Taking glass-melt in the annual output of 80,000 t furnace as the research object,the author analyzes the distribution of temperature field,velocity field and power field of molten glass in the furnace by using ANSYS software to simulate the production state of the furnace.At the same time,the influence of different parameters on the distribution of temperature field and velocity field of molten glass in furnace was calculated.Combined with the production practice,the actual flow field optimization of glass-melt in the furnace is proposed.
