Title:
MARINE ORGANISM STICKING PREVENTION DEVICE
Document Type and Number:
Japanese Patent JPH04148313
Kind Code:
A
Abstract:
PURPOSE:To automatically control the generation and injection rate of sodium hypochlorite by controlling the flow rate of sea water including the sodium hypochlorite flowing to a water injecting unit, and controlling the sea water flowing to the electrolytic cell of a sea water electrolytic device connected serially to be always a constant rate. CONSTITUTION:The sea water intaken by a sea water intaking pump 1 is feeded to a receiving cell 4, fed to a sea water electrolytic device 25 by an electrolyte injecting pump 7, and electrolyzed in order to obtain the sea water including the sodium hypochlorite. Then, the sea water is again returned through a reflux pipe to the receiving cell 4, the sea water flowing through a supply pipe is made to include the sodium hypochlorite, one part of the sea water is fed to each water injecting unit 28, and to each circulating water pump line. Also, a flowmeter 10a and a flow rate regulating valve 11 or the like are provided at each stage in order to control the flow rate of the sea water. Thus, the generation and injection rate of the sodium hypochlorite can be automatically controlled, and each device can be efficiently operated.
