    摘要: 本文探討捆線傾角對兩端進出料型捆線熱擴散塔提煉重水之影響,並推導出最佳傾角之計算公式。結果發現:若以最佳傾角之捆線環繞於同心套管熱擴散中,可適度減弱對流強度而抑制再混合效應,進而提高分離度。 The equations which may be employed to predict the optimum wire angles of inclination for enrichment of heavy water in a concentric-tube thermal-diffusion column with a tight fitting wire spiral, having a diameter equal to the annular spacing, wrapped on the entire inner tube, operating with transverse sampling streams, have been derived. Considerable improvement stead of the absence of wire spiral, so that the convection strength can be properly reduced and controlled, resulting in suppressing the undesirable remixing effect while still preserving the desirable cascading effect. Accordingly, essential savings in fixed charges and operating expense can be achieved, particularly for lower production rate operations or for smaller degree of separation.
