no. 1 approach

[0029] An electrolysis system 1 according to a first embodiment of the present invention will be described in detail with reference to the drawings.

[0030] figure 1 It is a schematic configuration diagram of the electrolysis system 1 according to the first embodiment of the present invention. Such as figure 1 As shown, the electrolysis system 1 is a system mainly including a combined cycle power generation facility P including a waste heat recovery boiler B, a seawater electrolysis device 2, and a control device (not shown).

[0031] Combined cycle power generation facility P (hereinafter, referred to as facility P) includes: a gas turbine (not shown); a waste heat recovery boiler B (hereinafter, referred to as boiler B) to which exhaust gas from the gas turbine is sent; a steam turbine (not shown); And a generator (not shown) that is driven by the rotational driving force of the gas turbine and the steam turbine to generate electricity.

[0032] The seawater M taken out ...

Abstract

An electrolysis system comprising: a seawater line through which seawater to be introduced into the plant flows; a nitrogen treatment tank into which nitrogen-containing waste water discharged from the plant is introduced; an electrolysis apparatus for electrolyzing seawater or brine to generate electrolyzed water with hypochlorous acid; an injection line for injecting the electrolyzed water into the seawater line; a branch line branching from the injection line for injecting the electrolyzed water into the nitrogen treatment tank.

Description

technical field [0001] The present invention relates to an electrolysis system including an electrolysis device that electrolyzes seawater or brine to generate electrolytically treated water containing hypochlorous acid. [0002] this application claims priority based on Japanese Patent Application No. 2014-228012 for which it applied on November 10, 2014, and uses the content here. Background technique [0003] Conventionally, in thermal power generation facilities and nuclear power generation facilities that use a large amount of seawater, the attachment and propagation of algae and shellfish to parts that come into contact with seawater, such as water intakes, piping, condensers, and various coolers, has become a problem. [0004] In order to solve this problem, the following anti-fouling device for marine organisms has been proposed, which generates sodium hypochlorite (chlorine, sodium hypochlorite salt) by electrolysis of natural seawater, and injects electrolyzed wate...
