Gaseous bubble injection device in liq. - for flotation of suspended and colloidal matter

Abstract

Abstract Gaseous bubbles are introduced by an injection device into a liq. in a recipient for the floatation of pulverulent or colloidal matter in suspension in water. Water is introduced into the emulsifier by the pump through a vertical tube. Air is admitted through the tube, with a peripheral emulsifier with a deflector immediately below its lower end. The emulsifier assembly is immersed in the water to be treated in the tank. The air emulsified in the water is deflected in the horizontal direction across the base of the tank, as shown by the arrows, the speed decreasing gradually under the effect of friction. Device is simple and uses but little energy. It supplies the flotation bath with a system of bubbles with a dia. 100 mu without causing eddies that would destoy the particle floccules or unstable agglomerates.
