Injectors and their use in gassing liquids

摘要: In an injector for the dispersion of a gas into liquid and comprising inlet, mixing chamber communicating with said inlets having inlet outlet, improvement wherein is substantially round in cross-section outlet slit-shaped, whereby kinetic energy propulsion can be utilized high efficiency to produce very fine bubbles. Advantageously cross-sectional area at about 5 25 times nozzle throat, has throat diameter d diverging its discharge angle 5° 10°, beginning distance from 1 3 end being circular d, length 20 height slit d. The especially suited use treating effluents fermentation processes.
