【摘要】：近年来,尽管我国钢化玻璃的产量非常大,但我国在生产钢化玻璃产品的过程中存在着产品质量不高和能耗大等问题。玻璃钢化炉是生产钢化玻璃最主要的设备之一,对玻璃钢化炉炉内温度场和流场研究,是合理设计和改进玻璃钢化炉的前提,也是生产更加高效节能玻璃钢化炉的要求。首先,论文论述了国内外玻璃钢化炉的研究现状、玻璃钢化工艺和钢化炉的加热方式,分析了钢化玻璃自爆与温度的关系,介绍了水平辊道式钢化生产线的发展。其次,论文通过数值传热学和流体动力学理论对钢化炉内传热方式及气体流动建立了数学模型。然后,利用CFD软件中的FLUENT14.0对玻璃钢化炉炉内温度场和流场进行数值模拟。在模拟过程中根据全辐射加热玻璃钢化炉结构特点,将其简化成二维几何模型,应用Laminar模型和DO辐射传热模型,将钢化炉加热过程分别选取三个典型的时间段对钢化炉炉内气体的温度场和流场进行模拟计算。通过计算机计算得到三个时间段炉内气体流场和温度场的分布规律。最后,论文总结出钢化炉加热过程中炉内气体的变化规律。这个课题的研究使我们对全辐射加热玻璃钢化炉炉内的情况认识更加清晰透彻,这必然会为加热效率更高的辐射—强制对流玻璃钢化炉的设计提供重要的参考依据。
[Abstract]:In recent years, although the production of tempered glass in China is very large. However, in the process of producing tempered glass in China, the quality of the product is not high and the energy consumption is large. Glass tempering furnace is one of the most important equipment for the production of tempered glass. The study of temperature field and flow field in glass tempering furnace is the premise of reasonable design and improvement of glass tempering furnace, and is also the requirement of producing more efficient and energy saving glass tempering furnace. This paper discusses the research status of glass tempering furnace at home and abroad, the glass tempering process and the heating mode of the furnace, and analyzes the relationship between the self-explosion of tempered glass and temperature. The development of horizontal roller steaming production line is introduced. Secondly, the mathematical model of heat transfer mode and gas flow in the furnace is established by numerical heat transfer and hydrodynamic theory. The temperature field and flow field in glass tempering furnace were simulated by FLUENT14.0 in CFD software. In the process of simulation, the structure characteristics of glass tempering furnace were calculated according to the total radiation heating. It is simplified into a two-dimensional geometric model, and the Laminar model and do radiative heat transfer model are applied. The temperature field and flow field of the gas in the furnace are simulated and calculated by selecting three typical time periods during the heating process of the furnace. The distribution rules of the flow field and temperature field of the gas in the furnace are obtained by computer calculation. Law. Finally. This paper summarizes the change of gas in the furnace during the heating process of the tempering furnace. The research of this subject makes us understand the situation of the glass tempered furnace with total radiation heating more clearly and thoroughly. This will provide an important reference for the design of radiation-forced convection glass tempering furnace with higher heating efficiency.
