DISPENSER Russian patent published in 1997 - IPC

FIELD: devices for splitting (dispersion) of gas bubbles in the flow of moving liquid to form gas-liquid mixtures in plants of pressure flotation and aeration of liquids. SUBSTANCE: located inside the body made in the form of successively located confuser, cylinder and diffuser is cylinder-conical barrier provided with collar having longitudinal grooves. Supplying nozzle is located for axial motion in body confuser. Barrier is installed in cylinder and discharge branch pipe is located in diffuser. Due to this, favorable hydrodynamic conditions are provided for multistage impact splitting of bubbles and their discharge under the conditions preventing coalescence. Body is made in the form of two halves between which barrier collar is clamped to simplify its manufacture as in this case there is no need in additional fastening of barrier inside the body, and it is reliably protected from displacement. EFFECT: higher efficiency. 3 cl, 3 dwg
