摘要

A certain amount of gas is directed under the liquid surface in a solution reactor, advantageously into the bottom of the reactor, for dispersing the gas into small bubbles and distributing it as evenly as possible over the entire cross-sectional area of the reactor. When the gas discharges and disperses from a flexible-structured member, the reaction force produced by the discharging gas imparts to the dispersing member a whip-like movement having a continuously decreasing radius of curvature. This movement produces strong mechanical mixing in the liquid. This is further enhanced by the strong gas jet discharging from the end of the dispersing member and changing its place randomly. Due to the resultant strong mixing, the solid in the reactor remains in motion and continuously maintains the good degree of suspension and does not accumulate in piles on the bottom of the reactor. Depending on the amount of the gas, the rising gas bubbles produce in the reactor effective vertical flows which further mix the solid.
