Abstract

PURPOSE: In the titled device of the perforated plate type, to improve agitating effect, by driving natural circulation more powerfully, using it in combination with forced circulation.
CONSTITUTION: The aerated agitator is set vertically in the water tank 1, and the partitions 5a and 5b for bubble rising are formed with their righest and lowest parts having proper intervals between them and the top cover 1a and the bottom cover 1b of the water tank 1. The aerated agitator consists of the partitions 5a and 5b, the multi-stage perforated plate 3 having the holes 3a set in the whole horizontal direction in the interior or outside of the partitions 5a and 5b, the hollow pipes 3a, 3b, and 3c passing through the perforated plate 3 protruding downward and/or upward and downward, and the gas dispersersing means 2 set at the interior of the lowest part of the partitions 5a and 5b. The agitating area A shows agitation consisting of the vertical flow of the liquid resulting from natural circulation and the rising flow of the liquid dragged by the gas rise resulting from forced circulation, and the falling flow area B exhibits an area where a falling flow in an amount corresponding to that of the raised liquid caused by forced circulation takes place.
