  1. 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的干壓降及場速度分佈分析對比后發現,固定閥周圍場存在較強的湍動,閥側孔與壁面區域以及閥體的上方空間存在明顯的渦區,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。
  2. The test was made on the compound tray, dual flow tray, sieve tray and valve tray for mass transfer efficiency with in - diameter 300 mm column using ethanoi and water system

    在直徑300mm的精餾內,以乙醇-水為介質,進行了復合穿、篩和浮閥的傳質效率的研究。
  3. The experiment ' s results show that the total and plat efficiency of the compound tray is over 100 %, the highest efficiency can be up to 122 % within the range of f factor i ~ 2. 5m / s ( kg / m3 ) i / 2, it is far higher than the efficiency of dual flow tray, sieve tray and valve tray

    實驗表明,復合的全效率和單效率在f因子1 2 . 5m s ( kg m3 ) 」 』范圍內,可超過100 ,最高效率達122 ,遠高於穿、篩和浮閥的效率。
  4. This paper analyzed the mechanism that gas and liquid flow through the holes according to the fluid characteristics of the compound tray, and put forward that there are three states of liquid flowing, gas flowing and blocked for the holes because of the foam fluctuating on the tray while the compound tray operates

    本文根據復合的氣液動特點,分析了氣液穿動的機理。根據前人的研究結果,提出復合在操作時,由於泡沫層的波動,其篩孔存在通氣、通液和阻塞三種狀態。
  5. The compound tray has no down comer, gas and liquid counter flow through the holes of on the tray

    復合不設降液管,氣液同時逆穿過篩孔。
  6. The compound tray researched in this paper consists of dual - flow tray and 50 - 1 ^ omm high structural packing which is directly put under the dual - flow tray. it has three mass transfer sections that is the foam section on the tray, the film section in the packing layer and the shower section under the packing, so it has very high mass transfer efficiency

    本文研究的復合是在穿之下緊貼一層50 150mm的規整填料所構成,它有三個傳質區,即上的泡沫區、填料層內的液膜區以及填料層下的淋降區,因此,具有很高的傳質效率。
