APPARATUS FOR INTRODUCING GAS FIRST OF ALL AIR INTO STREAMING LIQUIDE

摘要

Gas is introduced into a flowing liq. (in particular air into water). The liq. stream is accelerated in a constriction and routed through a gap into a mixing chamber. A gas space is also located between the mixing chamber and the constriction. The gap can be changed. - The mixing chamber is equipped with elements creating turbulence. These elements are in the form of rotatable discs with perforations. A chamber imparting a rotary motion to the liq. is located downstream of the mixing chamber.(Dwg.0/0)
