摘要：A new static mixer Cross-over-Disc has been invented to strip off the boundary layer and to make strong radial mixing.The pressure drop of Cross-over-Disc is 12–26 times as large as that of empty pipe with equivalent diameter and length.The mixing performance of Cross-over-Disc with 14 elements has been investigated in the viscosity range of 190–250 Pa·s by decoloration method,and the gray analysis of images shows that mixing inhomogeneity is about 7.5%and 9.4%for the mixing ratio of 5∶1 and 10∶1,respectively.Furthermore,mixing inhomogeneity for a combination of static mixing elements(four from Cross-over-Disc and three pairs from Sulzer-type)can be decreased to 2.1%–3.1%within a reasonable range of pressure drop.
