A more comprehensive mathematic model is presented for the process of vacuum desorption to remove gases from water in a packed column. This mode1 involves the mass, heat and momentum transfer. Owing to lacking of mass transfer coefficient for the gas phase, a numerical solution has been obtained by introducing a correction factor. An optim um tower pressure exists, which must be a little higher than saturate d vapor press ure of the entering water when the temperature of water is given. At this pressure, as the stripping steam maintains mere1y the stripping operation of entire tower (There is neither any excess of steam nor any evaporation of water taking place at tshe adiabatic condition), the steam consumption is most economical. For removing the relatively insolub1e gases dissolved in water, such as O2 or N2, the height of packing bed can be estimated according to the equa- tion 1n(XTi/xBi) =z·Lai/L, which does not depend on the stripping factor. The pressure drop of gases through packing bed is an important parameter in the operation, since it concerns the steam consun1ption.

本文就传质、传热和流体阻力几方面着手分忻,从而对填料塔中真空汽提脱气过 程建立了数学模型,并据此计算了塔内气液两相的温度分布,浓度分布以及压力变化 等。 当进水温度一定时,存在一个最佳的塔压,它应稍高于进水温度的饱和蒸汽压; 在最佳塔压下,刚好保证整个滇料层在汽提下操作而没有绝热蒸发时的汽提蒸汽量为 最经济的用汽量.

Concurrent vacuum degasification can lower the dissolved oxygen in water to theextent of 10 ppb, though it has one equilibrium stage at most.

The above qualificationcan be attained if the temperature of inlet water is slightly higher than the saturatedtemperature of water under the pressure at the bottom of the column.

Concurrent vacuum degasification can lower the dissolved oxygen in water to theextent of 10 ppb, though it has one equilibrium stage at most. The experiment wascarried out in a packed column with a diameter of 20mm and packing height of 1.7m,which corresponds to six mass transfer units based on liquid phase. The above qualificationcan be attained if the temperature of inlet water is slightly higher than the saturatedtemperature of water under the pressure at the bottom of the column. This is becausethe self-evaporated water vapor plays the role of stripping vapor. However, for countercurrent process, this effect cannot be obtained if the stripping steam is not introduced.

并流真空脱气过程虽然最多只能相当于一个平衡级,但在理论上可以使水中的溶解氧降到10ppb以下。在直径为20mm填料层、高度为1.7m的填料塔(相当于6个液相传质单元数)中进行了试验,结果证明,只要进水温度略高于塔底压力所对应的饱和温度,就足以达到上述要求。这是因为自蒸发的水蒸汽本身起到了汽提作用。而对逆流过程而言,如果不供给汽提蒸汽,则是达不到的。
