STERILIZING AND WASHING OF CONTINUOUS ELECTROLYTIC WATER-MAKING APPARATUS, AND CONTINUOUS ELECTROLYTIC WATER MAKING APPARATUS EQUIPPED WITH WASHING MECHANISM FOR THE EXECUTION

摘要

PROBLEM TO BE SOLVED: To sterilize a water supply pipeline, cathode chamber and drain pipe on the downstream side of an adsorbing water purifier by passing acidic water formed in an anode chamber through an electrolytic cell from the water supply pipeline on the side of a cathode chamber containing a microfilter to discharge the same from a cathode chamber drain pipe. ;SOLUTION: A water supply pipeline 8 on the side of a cathode chamber and the water supply pipeline 9 on the side of an anode chamber are respectively independently connected to the water supply sides of the cathode chamber 6 and anode chamber 7 of a diaphragm electrolytic cell 2 and a cathode chamber drain pipeline 10 and an anode chamber drain pipe 11 are respectively independently provided to the drain sides of the cathode chamber 6 and the anode chamber 7. The valve disc 24 of a passage control means 18 is provided at a washing position, that is, stops the supply of raw water to a water supply pipeline 8b on the side of the cathode chamber containing a microfilter and allows a water supply port 22 and a drain port 23 to communicate with each other to drain acidic water formed in the anode chamber 7 from the cathode chamber 6 and the drain pipeline 10 through the water supply pipeline 8b on the side of the cathode chamber. By this constitution, the water supply pipeline 8b on the side of the cathode chamber, cathode chamber 6 and drain pipeline 10 on the downstream side of an adsorbing water purifier 12 an be sterilized and washed.;COPYRIGHT: (C)1998,JPO
