【摘要】：鍋爐占據(jù)著國民經(jīng)濟(jì)中舉足輕重地位,以鍋爐產(chǎn)生的熱能推動著各個行業(yè)的發(fā)展。鍋爐水循環(huán)系統(tǒng)則是鍋爐系統(tǒng)的核心所在,關(guān)鍵的能量的轉(zhuǎn)換均在水循環(huán)系統(tǒng)中進(jìn)行。水循環(huán)系統(tǒng)在運行中不僅承著受高溫、高壓與腐蝕,還得面臨司爐工誤操作與維護(hù)不足等不利因素極易造成鍋爐水循環(huán)事故。本文首先分析鍋爐的社會意義并根據(jù)國家安全生產(chǎn)監(jiān)督管理總局給出的統(tǒng)計數(shù)據(jù)分析鍋爐的常見問題;然后以常見問題為依據(jù)選取出鍋爐系統(tǒng)中關(guān)鍵子系統(tǒng)—鍋爐水循環(huán)系統(tǒng)進(jìn)行進(jìn)一步的研究;接著以鍋爐水循環(huán)事故的演變過程為主干,分析在不同階段進(jìn)入系統(tǒng)的輸入輸出事件,并以熱力學(xué)為理論基礎(chǔ)建立鍋爐水循環(huán)的數(shù)學(xué)模型;然后分析水循環(huán)系統(tǒng)內(nèi)的傳熱效率,計算上升管的水動力與阻力大小,并鍋爐自然循環(huán)故障的常見原因,同時以傳熱學(xué)、流體力學(xué)為基礎(chǔ)建立數(shù)學(xué)模型;最后為了能夠真實的再現(xiàn)鍋爐事故的情景,模擬鍋爐事故發(fā)生的演變過程,本文將以3ds Max為建模工具、Unity 3D為驅(qū)動引擎以及C#為編程語言進(jìn)行本課題的開發(fā)。同時為了更好的呈現(xiàn)仿真效果,降低硬件渲染壓力,本課題將嘗試采用的一種新的方法Shader去編輯自定義的材質(zhì)效果。本文的研究實現(xiàn)了鍋爐水循環(huán)系統(tǒng)的狀態(tài)模擬,能夠真實的模擬鍋筒中的水位變化與液面沸騰狀態(tài),能夠模擬在不同工況下下降管與上升管中工質(zhì)的流動、汽水兩相的轉(zhuǎn)化與管道本身受熱后的狀態(tài)變化等。此水循環(huán)系統(tǒng)模擬軟件的意義在于能夠幫助操作人員理解鍋爐運作的原理,學(xué)習(xí)基本操作流程并提高緊急狀態(tài)下的應(yīng)急操作能力,這將有利于降低因司爐工誤操作而導(dǎo)致的鍋爐水循環(huán)事故。
[Abstract]:Boiler occupies a pivotal position in the national economy and promotes the development of various industries with the thermal energy generated by the boiler. Boiler water circulation system is the core of boiler system, and the key energy conversion is carried out in water circulation system. The water circulation system is not only subjected to high temperature, high pressure and corrosion, but also faced with the unfavorable factors, such as improper operation and insufficient maintenance of boiler workers, which can easily lead to boiler water circulation accident. This paper first analyzes the social significance of boiler and analyzes the common problems of boiler according to the statistical data given by the State Administration of production Safety Supervision and Administration. Then, based on the common problems, the key subsystem of boiler water circulation system is selected for further study, and then the evolution process of boiler water circulation accident is taken as the main part. The input and output events entering the system at different stages are analyzed, and the mathematical model of boiler water circulation is established on the basis of thermodynamics, and then the heat transfer efficiency in the water circulation system is analyzed to calculate the hydrodynamic force and resistance of the riser. At the same time, the mathematical model is established on the basis of heat transfer and fluid mechanics. Finally, in order to reproduce the scene of boiler accident, the evolution process of boiler accident is simulated. This paper uses 3ds Max as modeling tool and C # as programming language to develop this subject. At the same time, in order to show the simulation effect better and reduce the pressure of hardware rendering, this paper will try to use a new method Shader to edit the custom material effect. The research in this paper has realized the state simulation of boiler water circulation system, which can simulate the water level change and the boiling state of liquid level in the boiler tube, and simulate the flow of the working fluid in the descending tube and the rising tube under different working conditions. The transformation of steam-water two-phase and the change of the state of the pipe itself after heating. The purpose of this water circulation system simulation software is to help operators understand the principles of boiler operation, learn the basic operation process and improve the emergency operation capability. This will help to reduce boiler water circulation accidents caused by boiler workers' misoperation.
