dc.description.abstract本研究主要之目的為設計一款新型的高效率旋風集塵器,藉由文獻研讀瞭解了旋風集塵器的設計原理、缺陷、改善方法、參數影響等,而後利用技術相當成熟的CFD軟體與3D建模軟體,進行不同結構之分析與研究。本研究將列出文獻研究的精要與本研究設計的新型高效率旋風集塵系統及最後的後續研究方向,期能透過本研究來開啟旋風集塵系統研究的新的里程碑。 本研究之新型旋風集塵器之集塵系統設計為在傳統的旋風集塵系統之圓錐處加入了粒子井的設計,透過粒子井特殊的設計,使部分粒子與氣體分離而被蒐集,其餘粒子則隨著氣體繼續向下往集塵盒方向前進,在接近集塵盒入口處,有另一阻擋器設計,此結構之尺寸與安裝位置,可避免氣體進入集塵盒而引起再揚起效應,藉此提高蒐集效率。 本研究當中證實了新型旋風集塵器之效能相較傳統旋風集塵器,性能有顯著的提升,在進氣流速為5m/s時,其新型之截取直徑較低(新型為8um而傳統為13um)、蒐集效率較高(於d50,新型之蒐集效率高於傳統50%)、壓力降降低約11%-14%、高度亦減少20%以上,整體性能相較傳統設計得到了全面性的提升。另外更驗證了使用Solidworks Flow Simulation來進行預測與優化旋風集塵系統是可行的,縱使可能會遭遇一些誤差,但在了解此軟體的誤差所在之後,技巧性地避開可能造成重大誤差之條件,研究者便可以善用Solidworls Flow Simulation之優勢,進行快速且大量的模型分析,而取得之結果亦具有合理之準確性。zh_TW
dc.description.abstractThis study is intent to design an new type of high efficient cyclone , via literature studying to understand the design basis and defect of cyclone , and the method to improve cyclone and the effect of each parameter , thereafter utilized 3D and CFD software to analyze and research the multiple construction of cyclone to find the best efficiency of cyclone . In this study , will present the essence of the previous literatures and show an new type of high efficient cyclone , the system of dust collection in the new one is made from the traditional one but added some particle traps on the cone area , the particular particle traps will capture some portion of particle from the air , the others will keep moving into the dust box , near the entrance of dust box , there is another obstacle , the dimensions of construction and the settled position could reduce the amount of air into the dust box , and then increase the collection efficiency This study confirmed the quality of new one is more efficient than the traditional one , such as , lower d_50 (the new one is 8um and the traditional one is 13um) , higher collection efficiency (when using the new one d_50 , the new one is higher than the traditional one about 50%) , low pressure drop (the new one is lower than the traditional one about 11%-14%) and the height of cyclone is lower than the traditional one about 20% , We can say that the new one got entirely advancement , also this study confirmed the feasibility of solidworks Flow simulation to analyze the cyclone system , even though there is deviation in the analysis , once we realized where/when/why caused the deviation , then we can dodge these condition which will cause the obvious deviation to do the right analysis , the researcher could perform solidworks flow simulation to analyze multiple cyclone and the results are reasonable and with enough accuracy .en_US
