VAESKE-GAS-DISPERSIONSREAKTOR

摘要

A dispersion of air or oxygen in liquid sewage and/or or sludge is admitted tangentially into the lower portion of an upright vessel wherein the dispersion rises and is compelled to flow through eccentric flow restricting passages in several superimposed horizontal partitions so that the dispersion is repeatedly induced to form a turbulent helical flow. The rising dispersion flows around a tube which returns a portion of the dispersion into the lower part of the vessel and causes the remaining portion to overflow into a receptacle having an outlet at a level below the open top of the tube. The dispersion which descends in the tube is readmitted tangentially into one or more chambers which are separated from each other by the partitions in the vessel and communicate with each other by way of the respective flow restricting passages.
