The homemade YSA8 type anion separating column can't separate F- ,Cl- ,NO3- and SO42- after loosing capability.

国产YSA8型阴离子分离柱,因失效无法分离F~-、Cl~-、NO_3~-和SO_4~(2-)4种离子,用HCl法处理,并重新选择合适淋洗液浓度后,能成功地分离F~-、Cl~-、NO_3~-和SO_4~(2-)。

This paper establishes a mathematical model of the gas flow field inside separating column of the circumfluent circulation cyclone separator based on the N-S equation under column coordinate,gives the resolution of the cyclone flow field in separating column with weighted residual method,and compares computation values with trial values as well.

由柱坐标系下的Navier-Stokes方程出发,建立了环流循环除尘系统分离柱内流速场新的数学模型,利用具有成熟使用经验的加权残值法对流场进行求解,并与实验结果进行了比较。
