BAFFLE FOR AGITATING VESSEL AND AGITATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide baffles for an agitating vessel which enhances a bubble holding rate in gas-liquid mixing and exhibits good gas-liquid mixing efficiency by generating downflow by baffles near a inner wall of the vessel.;SOLUTION: Whirling flow caused by rotation of agitating blades 3 collides with the baffles 4, 5 and 6 roughly vertically provided in the vicinity of the inner wall of the agitating vessel 1 to be converted to a vertical flow. An overlapped part of the baffles 4 and 5 or baffles 5 and 6, an upflow generated by the baffle 5 (or 6) located ahead of the whirling flow is converted into a flow streaming around the upper ends of the baffles, and joins with the downflow generated by the baffle 4 (or 5) located upward. The composed flow passes through a space between the baffles and descends along the rear surfaces of the baffles as the downflow.;COPYRIGHT: (C)2004,JPO
