  3. In addition, the hf in the downcomer of ctst plate is 110 ~ 150mm lower than that of fl valve plate. it was showed that making a comparison of two plates, the downcomer of ctst tray can cope with more operation loads with the same size downcomers

    這說明相同大小的降液管， ctst塔板上的降液管可處理的操作負荷比浮閥塔板的要大；即若在相同的操作負荷下，在設計降液管時， ctst塔板的降液管尺寸可比浮閥塔板的小。
  4. By comparing the dry plate pressures drop and distributions of velocities simulated on single valve with those of double valves, it was found that there was intense turbulence in the flow fields around fixed - valve, there were eddy areas between valve side orifices and tray wall, there were eddies above the valves too, these led to the complex behaviors of gas perforating valve, these had a great effect on the gas - liquid mass transfer process. at the same time, in order to prevent the disadvantageous effect of gas between one valve with another on the gas - liquid mass transfer, it was very effective to change the fields of gas perforating valve by folding the edges of valve

    通過對數值模擬得出的單閥和雙閥塔板的干板壓降及流場速度分佈分析對比后發現，固定閥周圍流場存在較強的湍動，閥側孔與塔板壁面區域以及閥體的上方空間存在明顯的渦流區，使氣體穿閥后的行為變得復雜，並對氣液傳質過程產生重大影響；模擬結果表明，為防止和削弱固定閥間的對沖造成的「死區」對傳質帶來的不利影響，通過折邊來改變氣體的氣路是非常有效的，模擬值與實驗值基本得到吻合。
  5. At first, in the process of experiments, it were measured that dry plate pressures drop and point pressures in the flow fields around the single fixed - valve and double fixed - valves under different velocities by using of pitot tube. after that point pressure was transformed to point velocity, two dimensions flow plane of flow fields around fixed - valve were plotted to observe the difference between of the fixed - valve tray with fold edges and the common rectangular fixed - valve tray on the distributions of flow fields and pressures, to provide comparisons and refer - rence for cfd simulation

    在實驗中，利用測速管等儀器對在不同速度下的單閥和雙閥固定閥周圍的流場進行了點壓力測量，然後把點壓力轉化為點速度后繪出固定閥周圍流場的二維流線圖，同時測定了塔板的干板壓降，來考察新型固定閥帶折邊后對流場分佈和壓降的影響，為隨后的數值模擬提供對比和依據。
