【摘要】:近年來(lái),盡管我國(guó)鋼化玻璃的產(chǎn)量非常大,但我國(guó)在生產(chǎn)鋼化玻璃產(chǎn)品的過(guò)程中存在著產(chǎn)品質(zhì)量不高和能耗大等問題。玻璃鋼化爐是生產(chǎn)鋼化玻璃最主要的設(shè)備之一,對(duì)玻璃鋼化爐爐內(nèi)溫度場(chǎng)和流場(chǎng)研究,是合理設(shè)計(jì)和改進(jìn)玻璃鋼化爐的前提,也是生產(chǎn)更加高效節(jié)能玻璃鋼化爐的要求。首先,論文論述了國(guó)內(nèi)外玻璃鋼化爐的研究現(xiàn)狀、玻璃鋼化工藝和鋼化爐的加熱方式,分析了鋼化玻璃自爆與溫度的關(guān)系,介紹了水平輥道式鋼化生產(chǎn)線的發(fā)展。其次,論文通過(guò)數(shù)值傳熱學(xué)和流體動(dòng)力學(xué)理論對(duì)鋼化爐內(nèi)傳熱方式及氣體流動(dòng)建立了數(shù)學(xué)模型。然后,利用CFD軟件中的FLUENT14.0對(duì)玻璃鋼化爐爐內(nèi)溫度場(chǎng)和流場(chǎng)進(jìn)行數(shù)值模擬。在模擬過(guò)程中根據(jù)全輻射加熱玻璃鋼化爐結(jié)構(gòu)特點(diǎn),將其簡(jiǎn)化成二維幾何模型,應(yīng)用Laminar模型和DO輻射傳熱模型,將鋼化爐加熱過(guò)程分別選取三個(gè)典型的時(shí)間段對(duì)鋼化爐爐內(nèi)氣體的溫度場(chǎng)和流場(chǎng)進(jìn)行模擬計(jì)算。通過(guò)計(jì)算機(jī)計(jì)算得到三個(gè)時(shí)間段爐內(nèi)氣體流場(chǎng)和溫度場(chǎng)的分布規(guī)律。最后,論文總結(jié)出鋼化爐加熱過(guò)程中爐內(nèi)氣體的變化規(guī)律。這個(gè)課題的研究使我們對(duì)全輻射加熱玻璃鋼化爐爐內(nèi)的情況認(rèn)識(shí)更加清晰透徹,這必然會(huì)為加熱效率更高的輻射—強(qiáng)制對(duì)流玻璃鋼化爐的設(shè)計(jì)提供重要的參考依據(jù)。
[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.
