摘要
本文是在分别采用改型θ环丝网填料和开孔波纹丝网填料，对水─—空气系统进行实测的基础上，对所获数据经过回归分析，得到了不同喷淋密度下干湿填料塔压降关联式，泛点气速关联式和持液量关联式。并与文献值进行比较，确认上述两种丝网填料具有高效、低压降和小持液量的特点。
This paper using changed一type θ一ring metal screen extender and corrugationmetal screen extender which made一holes,under the fundamental of actualadmensuerment for the system of water and air.By the regression analysis based on thedatum,get the relationship between spray density and pressure drop for dry and wet ex-tender tower,as well as the relationship between flooding一piont velocity and the quantityof holding一water.After compared with the articles value,confirmed those two typesmetal screen extender which mentioned above have the characteristics of high effeciency,low pressure drop and small quantity of holding一water.
