文氏洗滌器之性能分析

Abstract

本文使用數值方法分析文氏洗滌器的性能，其方法如下，利用數值模擬軟體，完成洗滌器內流場狀況與吸附劑在洗滌器中的分佈狀況之模擬，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器的性能，並在不同液氣比及水滴粒徑狀況下，比較所得效率。

This paper is to study adsorption efficiency in Venturi scrubber numerically. The adsorption model which includes the ratio of remnant capacity and the concentration effect is proposed , and the size and the trajectory of water droplet are considered to calculate the adsorption efficiency. The solver of CFD code is need to execute numerical computation. The results revealed that the effects of the mass flow rate of the water droplet and the trajectory of water droplet on the adsorption efficiency are remarkable . The adsorption efficiency could be over 95% under large liquid gas ratio.
