AERATOR Russian patent published in 2000 - IPC

FIELD: process equipment for treatment of multiphase systems, particularly, devices for aeration and saturation of liquid with gas. SUBSTANCE: aerator has header on which air distributing branch pipes are installed for air supply. Branch pipes are located over circumference of header provided with inlet pipe. Branch pipes have horizontal slots which are located symmetrically, one opposite the other and overlapped by polymer or metal wire cloth attached to branch pipe outer side. Ends of each branch pipe are closed with plugs. Compressed air or gas is supplied through inlet pipe and distributed among branch pipes. Air or gas from branch pipe passes through slots overlapped by wire cloth and enters the liquid to be aerated in the form of air bubbles proportional to slot width which is determined by expression given in the invention description. EFFECT: improved distribution of gas, higher efficiency of mass transfer process and considerable simplification of design as a whole. 5 dwg
