本文討論傾斜角對以塔端進出料型平版熱擴散塔提煉重水之影響,逐漸而推導出預測最佳傾斜角之計算公式。結果發現:若該塔以最佳角度傾斜,可適度減弱對流強度而抑制再混合效應,進而增加分離度。 The equations which may be employed to predict the optimum angles of inclination for enrichment of heavy water in an inclined flat-plate thermal-diffusion column with transverse sampling streams, have been derived. Considerable improvement in performance is obtainable if the column is tilted at the optimum angle, instead of being placed vertically, 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.
