濕式洗滌塔之流場均勻化分析

Abstract

本文使用數值方法分析填充式濕式洗滌塔的性能，其方法如下，利用數值模擬軟體，完成洗滌塔內流場狀況，再藉由所得的資料，代入剩餘容積比與濃度效應之吸附模式中，使用數值方法計算出洗滌塔的性能，並在不同洗滌水體積的模式及改變理論公式的係數下，比較所得效率。為改善傳統填充式濕式洗滌塔的過濾效率，設計一孔洞檔板使其流場均勻化，並比較流場均勻化的好壞是否會影響洗滌塔之過濾效率。

This paper is to study adsorption efficiency in Wet scrubber numerically. The adsorption model which includes the ratio of remnant capacity and the concentration effect is proposed , also the different model of water volume and different coefficient of the theoretically formula are considered to calculate the adsorption efficiency. The solver of CFD code is need to execute numerical computation. In order to improve the efficiency of wet scrubber, we design a porous plate, expect that can have uniform flow inside the scrubber. Finally, we discuss the efficiency between the improved scrubber and the old one, and we can find that there is about 3% enhancement by using the porous plate.
