HYPOCHLOROUS ACID WATER SUPPLY DEVICE AND SPACE STERILIZATION SYSTEM USING THE SAME

To provide a hypochlorous acid water supply device capable of generating hypochlorous acid water with reduced residual components caused by electrolysis of salt water, and a space sterilization system using the same.SOLUTION: A hypochlorous acid water supply device 1 includes: a serpentine electrolytic flow path configured to supply salt water; a hypochlorous acid water generating unit 1a for continuously electrolytically generating hypochlorous acid water by energizing between a pair of cathode and anode electrodes (between a cathode 2 and an anode 3) from salt water supplied in a non-diaphragm electrolytic flow path (a flow path 12 between the cathode and the anode) constituting a preceding stage of the electrolytic flow path; and a hypochlorous acid water treatment unit 1b that continuously treats hypochlorous acid water supplied from the hypochlorous acid water generating unit 1a to each of diaphragm-equipped electrolytic flow paths (a cathode side flow path 13 and an anode side flow path 14) that constitute a subsequent stage of the electrolytic flow path by energizing between the pair of anode and cathode electrodes (between the cathode 2 and the anode 3), in which the hypochlorous acid water sent out from the electrolytic flow path on the cathode 2 side of the hypochlorous acid water treatment unit 1b is supplied to outside.SELECTED DRAWING: Figure 1 【課題】塩水の電気分解によって生じる残留成分を低減した次亜塩素酸水を生成することが可能な次亜塩素酸水供給装置及びこれを用いた空間除菌システムを提供する。【解決手段】次亜塩素酸水供給装置１は、塩水を供給可能に構成された蛇行状の電解流路と、電解流路の前段を構成する無隔膜電解流路（陰陽電極間流路１２）内に供給される塩水から一対の陰陽電極間（陽電極２と陰電極３との間）への通電によって次亜塩素酸水を連続的に電解生成する次亜塩素酸水生成部１ａと、電解流路の後段を構成する有隔膜電解流路（陽電極側流路１３及び陰電極側流路１４）内のそれぞれに次亜塩素酸水生成部１ａから供給される次亜塩素酸水を一対の陰陽電極間（陽電極２と陰電極３との間）への通電によって連続的に処理する次亜塩素酸水処理部１ｂと、を備え、次亜塩素酸水処理部１ｂの陽電極２側における電解流路から送出される次亜塩素酸水を外部に供給する。【選択図】図１
