摘　　要：根据落膜塔原理 ,一个中试湿法烟气脱硫 (WFGD)系统被建立用来模拟工业气液并流填料塔的 SO2 吸收过程。该系统由 10 0 k W的天然气燃烧器、直径3.2 6 cm高 5 m的湿壁塔和 110 L的持液槽等组成。该系统能等温操作 ,主要操作参数如进塔 SO2 浓度、浆液 p H值和 L/G比等能被控制在设定值。该系统能用于石灰石 /石灰的 WFGD研究 ,同时为湿壁塔A pilot- scale system of wet flue gas desulfurization(WFGD) ,based on the falling file principle,has been built to simulate SO2 absorption of a full- scale wet FGD packed tower with co- current gas- slurry flow.The system consists of the natural gas burnerof 10 0 k W,the wetted- wall column with an inner diameter of 3.2 6 cm and a length of 5 m,and the holding tank of 110 L .The system can be isothermally operated.The main operating parameters,i.e.inlet concentration of SO2 ,p H value of the slurry,and L/ G ratio can be controlled atvalues desired.The system can be used to investigate limestone/ lime WFGD,and also provide the base of wet FGD model of the wetted- wall columm and the experimental tool to evaluate the model predictions.
