Abstract

PURPOSE: To inexpensively obtain chlorite of high purity by interlocking an analyzer for determining the concns. of chlorine dioxide and chlorine quantitatively and automatically and a flow rate regulation valve or the like to adjust the amounts of a basic substance and a reducing agent fed.
CONSTITUTION: Chlorine dioxide gas is introduced into absorption tower 11 through flowmeter 17, and in tower 11 it is brought into counter-current contact with a mixed soln. of NaOH and H2O2 as an absorbing soln. to continuously obtain an aqueous NaClO2 soln. Part of a mixed gas at the inlet of tower 11 is introduced into chlorine dioxide analyzer 15 to determine the concns. of chlorine dioxide and chlorine quantitatively and automatically, and the concns. are outputted to interface 16. Interface 16 and flow rate regulation valve 19 for an aqueous NaOH soln. are interlocked through transmitter 18, and interface 16 and flow rate regulation valve 2 for an aqueous H2O2 soln. through transmitter 18. Interface 16 receives signals from analyzer 16 and flowmeter 17 and makes a predetermined calculation, and the results are converted into electric signals with transmitters 18, whereby valves 19, 20 are actuated to feed the solns. to receiving tank 12.
