ADJUSTMENT APPARATUS FOR LIQUID SURFACE LEVEL OF ACID PRODUCING TANK AND ADJUSTMENT METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an adjustment apparatus for the liquid surface level of an acid producing apparatus capable of ensuring a gas-liquid separation length and reducing the overflow of air bubbles to a discharge line, and an adjustment method using the same.;SOLUTION: A control device 10 monitors the output of a liquid surface meter 9 to adjust the opening degree of the adjusting valve 81 on the discharge line 8 corresponding to a liquid surface. By this constitution, the flow rate of water overflowing into the acid producing tank 3 from the upper end 7U of a gas-liquid separator 7 is adjusted while keeping the flow rate of treated water through the gas-liquid separator 7 to adjust the liquid surface level in the acid producing tank 3.;COPYRIGHT: (C)2004,JPO
