Arrangement for dilute concentrated poly from solutions

摘要

The output of mixing devices of the type described in U.S. Pat. No. 4, 057,223 may be substantially improved by attaching to the outlet of such mixing devices a vertical line containing flow control means, eductor means, and a long leg which communicates with a discharge line for feeding dilute water-soluble polymer solution. The discharge line is perpendicular to the leg and is fitted with a second flow control means. PPWhile the invention is useful for increasing the efficiency of the devices of the type described in U.S. Pat. No. 4,057, 223, it may be adapted to improving other mixing devices.
