• 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
  通过对数值模拟得出的单阀和双阀塔板的干板压降及流场速度分布分析对比后发现，固定阀周围流场存在较强的湍动，阀侧孔与塔板壁面区域以及阀体的上方空间存在明显的涡流区，使气体穿阀后的行为变得复杂，并对气液传质过程产生重大影响；模拟结果表明，为防止和削弱固定阀间的对冲造成的“死区”对传质带来的不利影响，通过折边来改变气体的气路是非常有效的，模拟值与实验值基本得到吻合。
• 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
  在实验中，利用测速管等仪器对在不同速度下的单阀和双阀固定阀周围的流场进行了点压力测量，然后把点压力转化为点速度后绘出固定阀周围流场的二维流线图，同时测定了塔板的干板压降，来考察新型固定阀带折边后对流场分布和压降的影响，为随后的数值模拟提供对比和依据。
• The pressure drop of the compound tray can be regarded as consisting of dry plate pressure drop , clear liquid resistance , liquid surface tension resistance , and packing pressure drop . the model that has established can fairly predict the pressure drop of the compound tray , the value calculated by the model compared with that detected by experiment is less than 20 %
  复合塔板的压降可认为由干板压降、清液层阻力、填料层压降和克服液体表面张力的压降四部分组成，所建立的压降计算模型，能较好地预测复合塔板的压降，计算值与实验值误差在20以内，可用于工程设计。
