【摘要】：在以增大端效应区为手段的旋转填料床(RPB)基础上设计了一种新型结构的RPB,即静态导流板式RPB,通过在主体填料区设置静态导流板,使周向运动的液体重新获取径向上的速度分量,液体重新被切割,产生第二端效应区,从而使气液传质效果得到加强。在脱碳实验中,对比静态导流板4种不同安装方式下的传质效果,结果表明,当导流板弧面切线方向与外填料垂直时,传质效果最好;CO2-Na OH气液传质实验的结果表明,安装静态导流板时设备的脱碳率比传统的满填料转子高5%左右,比未安装导流板时高10%左右;在H2S-CO2-MDEA的竞争反应体系中,H2S的脱除效率较高,选择因子较大,脱硫效率大于99.8%,净化气中H2S体积分数低于0.002%,同时选择性因子高达13.5。
[Abstract]:On the basis of rotating packed bed (RPBs) with increasing the end effect zone, a new type of RPB-static diversion plate RPBis designed. By setting the static baffle in the main packing area, the circumferential moving liquid can reacquire the velocity component in the radial direction. The effect of gas-liquid mass transfer is enhanced by cutting the liquid again and producing the second end effect zone. In the experiment of decarburization, the mass transfer effect under four different installation modes of static diversion plate is compared, and the results show that, When the tangent direction of the arc surface of the guide plate is perpendicular to the outer packing, the result of the gas-liquid mass transfer experiment of CO2-NaOH shows that the decarburization rate of the equipment is about 5% higher than that of the traditional full-packed rotor when the static guide plate is installed. In the competitive reaction system of H2S-CO2-MDEA, the removal efficiency of H2S is higher, the desulfurization efficiency is larger than 99.8, the volume fraction of H2S in the purified gas is lower than 0.002 and the selectivity factor is up to 13.5.
