循環(huán)流化床鍋爐流動特性的圖像分析研究


 


摘  要   本研究主要在前人的基礎(chǔ)上通過自行設(shè)計圖像處理軟件并且結(jié)合傳統(tǒng)的圖像采集技術(shù)對循環(huán)流化床氣固兩相流作出簡單的分析研究。研究的內(nèi)容主要包括：1. 制作基于MATLAB具有人機交互界面的圖像分析處理軟件。2.本文的圖片通過實驗來獲取，實驗的模型整體高3470mm，橫截面最大尺寸為300mm×280mm，實驗采用的床料為各種粒徑的玻璃微珠。實驗中我們對不同工況、不同顆粒度、不同高度的床料以及不同高度區(qū)域進行了長時間的連續(xù)拍攝，首先分析了影響底部區(qū)域氣泡大小、形狀的因素，以及計算氣泡的面積比。其次分析了CFB中不同情況下的顆粒團（簇）以及影響顆粒團（簇）的各種因素。

Abstract  This study is based on the previous ,image processing software is designed by myself and combine the traditional image acquisition phase flow circulating fluidized bed technology to make a simple analysis. Contents of the study include: 1. Making a computer interface based on MATLAB image analysis software. 2. This picture by experiment to obtain experimental model of the overall high-3470mm, the largest cross-sectional size of 300mm × 280mm, experimental bed materials used for various size of glass beads. We experiment with different conditions, different particle size, bed material of different heights and different height regions of the long continuous shot, The first analyzes the impact of the bottom of the regional bubble size, shape factors, and to calculate the bubble area ratio. Second, analysis of the CFB in the case of particles of different groups (clusters) and the impact of particle groups (clusters) of various factors.
