    • 以傳統氣送分離方式處理沾塵濾材循環再生系統，其缺點最嚴重者包括濾材容易破碎及粉塵分離不完全，因而以振動篩分方式將粉塵與過濾床質分離，是一項良好的解決方案。本研究目的為設計此一振動篩分系統，可為高溫過濾器循環再生系統所使用。我們先以分批篩分的研究，得到能夠有效分離濾材與相關粉塵之振動條件，進而在相同振動條件下改變篩網孔徑大小，獲得較佳的振動條件與篩網孔徑等參數。另外，更進一步設計一套振動篩分輸送裝置運用在顆粒床過濾器上，將分批篩分等參數運用在此連續式的篩分系統上。研究結果顯示，此系統能有效分離濾材與粉塵，並不會造成濾材在輸送過程中破碎。

    In a regeneration of filter granular system, the mainly disadvantages of sand/fly ash segregation by using traditional pneumatic transportation are sand broken and incomplete segregation. However, using vibrating screen to segregate sand and fly ash is a good method. The purpose of this study is to design a vibrating screen system, which can be applied into the regeneration of filter granular system in high temperature. First, the batch vibrating screen experiments are carried out to explore the optimum vibrating conditions which can separate sand and fly ash efficiently. The influence of screen aperture size on the screen efficiency and screen rate are also investigated in the batch screen experiments. Moreover, the results of optimum vibrating conditions from the batch screen experiments are applied into the continuous vibrating screen system. We add the continuous vibrating screen into the granular filter bed. The result demonstrate that the vibrating screen system can segregate sand and fly ash efficiently with less sand broken.
