Description

本発明の実施形態は、空間殺菌装置及び空間除臭装置に関する。   Embodiments described herein relate generally to a space sterilization apparatus and a space deodorization apparatus.

従来、空気中に浮遊する菌を殺菌する目的や空間の除臭をする目的で次亜塩素酸水を空間中に噴霧することにより浮遊菌が殺菌されること、メチルメルカプタンやトイレ臭が除臭されることが知られており、除臭目的で空間中に噴霧する装置も販売されている。   Conventionally, suspended bacteria are sterilized by spraying hypochlorous acid water into the space for the purpose of sterilizing bacteria floating in the air or deodorizing the space, and methyl mercaptan and toilet odors are deodorized. Devices that spray into the space for the purpose of deodorization are also sold.

ところで、殺菌、除臭に対して室内空間に噴霧される濃度が少ないと殺菌、除臭に対して効果がなく、また多すぎると酸性ガスが充満し、空間内の金属製品が錆びたり、健康を害する等の悪影響を受ける可能性がある。
例えば８．１ｍ３の密閉空間にあるメチルメルカプタンに対し、５０〜１５０ｐｐｍの濃度の次亜塩素酸水を２５〜３０ｍｌ噴霧し、除臭効果が得られることが開示されているが、場所による濃度ばらつきや失活などにより除菌や除臭に効果的となる空間中の濃度は不明である。 By the way, if the concentration sprayed into the indoor space for sterilization and deodorization is low, it will not be effective for sterilization and deodorization, and if it is too much, it will be filled with acid gas, rusting the metal products in the space, health May be adversely affected.
For example, it is disclosed that 25 to 30 ml of hypochlorous acid water having a concentration of 50 to 150 ppm is sprayed on methyl mercaptan in a closed space of 8.1 m 3 to obtain a deodorizing effect. The concentration in the space that is effective for sterilization and deodorization due to variations and inactivation is unknown.

第１の実施形態にかかる空間殺菌装置は、被処理空間にガス状及び／または霧状の次亜塩素酸水を供給する次亜塩素酸水供給部を含み、被処理空間中の次亜塩素酸濃度を４００ｐｐｂないし５００ｐｐｍにすることができる。
また、第２の実施形態にかかる空間除臭装置は、被処理空間にガス状及び／または霧状の次亜塩素酸水を供給する次亜塩素酸水供給部を含み、前記被処理空間中の次亜塩素酸濃度を４００ｐｐｂないし５００ｐｐｍにすることができる。 The space sterilization apparatus according to the first embodiment includes a hypochlorous acid water supply unit that supplies gaseous and / or mist-like hypochlorous acid water to the treated space, and hypochlorous acid in the treated space. The acid concentration can be 400 ppb to 500 ppm.
Moreover, the space deodorization apparatus concerning 2nd Embodiment contains the hypochlorous acid water supply part which supplies gaseous and / or fog-like hypochlorous acid water to a to-be-processed space, In the said to-be-processed space The hypochlorous acid concentration can be 400 ppb to 500 ppm.

実施形態によれば、次亜塩素酸水供給部により被処理空間にガス状及び／または霧状の次亜塩素酸水を供給して、被処理空間中の次亜塩素酸濃度を４００ｐｐｂないし５００ｐｐｍとすることにより、次亜塩素酸水による悪影響が無く、かつ十分な殺菌及び除臭効果が得られる。   According to the embodiment, gaseous and / or mist-like hypochlorous acid water is supplied to the processing space by the hypochlorous acid water supply unit, and the hypochlorous acid concentration in the processing space is set to 400 ppb to 500 ppm. By doing so, there is no adverse effect of hypochlorous acid water, and sufficient sterilization and deodorizing effects can be obtained.

なお、ここでは、殺菌とは、被処理空間の菌の少なくとも一部を殺すことをいう。
また、除臭とは、菌の繁殖を抑制し、臭気の発生、あるいは発散を防ぐことをいう。
次亜塩素酸水は、次亜塩素酸分子（ＨＣｌＯ）と次亜塩素酸イオン（ＣｌＯ−）とを平衡して含んでおり、ＨＣｌＯはＣｌＯ−に比較し強い殺菌力を有する。両者の構成比率はｐＨによって変化し、アルカリ性領域ではＣｌＯ−の比率が高くなり、弱酸性領域ではＨＣｌＯが多くなるため、強い殺菌力を発揮できる。なお、塩素ガス（Ｃｌ２）の殺菌力は、ＣｌＯ−の殺菌力よりも低い。 Here, sterilization means killing at least a part of the bacteria in the treated space.
Deodorization refers to inhibiting the growth of bacteria and preventing the generation or emission of odors.
Hypochlorous acid water contains hypochlorous acid molecules (HClO) and hypochlorite ions (ClO − ) in equilibrium, and HClO has a stronger bactericidal power than ClO − . The constituent ratio of the two changes depending on the pH, and the ratio of ClO − is high in the alkaline region, and HClO is increased in the weakly acidic region, so that strong sterilizing power can be exhibited. The sterilizing power of chlorine gas (Cl 2 ) is lower than that of ClO − .

図１に、例えば温度２５℃における次亜塩素酸状態図の一例を示す。
図中、電解水は、ｐＨにより、ＳＡ領域では強酸性電解水、ＷＡ領域では弱酸性電解水、ＭＡ領域では微酸性電解水、ＡＩ領域では電解次亜水となっている。
次亜塩素酸水供給部は、次亜塩素酸水をガス状にする気化装置、または霧状にする噴霧装置を含むことができる。 FIG. 1 shows an example of a hypochlorous acid phase diagram at a temperature of 25 ° C., for example.
In the figure, depending on the pH, the electrolyzed water is strongly acidic electrolyzed water in the SA region, weakly acidic electrolyzed water in the WA region, slightly acidic electrolyzed water in the MA region, and electrolyzed sub-aqueous water in the AI region.
The hypochlorous acid water supply unit can include a vaporizer that makes the hypochlorous acid water in a gaseous state, or a spraying device that makes it mist.

また、実施形態に係る空間殺菌装置は、次亜塩素酸濃度を計測するシステムをさらに含むことができる。
一実施形態において、次亜塩素酸濃度を計測するシステムは、例えば、被処理空間内のガス状及び／または霧状の次亜塩素酸水を採取する容器及び前記容器内に収容され、次亜塩素酸と反応して発光する蛍光試薬を含む次亜塩素酸水採取部と、発光強度計測部とを含み、発光強度から次亜塩素酸濃度を算出することができる。 Moreover, the space sterilization apparatus which concerns on embodiment can further contain the system which measures hypochlorous acid concentration.
In one embodiment, a system for measuring hypochlorous acid concentration includes, for example, a container for collecting gaseous and / or mist-like hypochlorous acid water in a processing space, A hypochlorous acid water collecting unit containing a fluorescent reagent that emits light by reacting with chloric acid and a luminescence intensity measuring unit are included, and the hypochlorous acid concentration can be calculated from the luminescence intensity.

使用される蛍光試薬として、アミノフェニルフルオレセイン（ＡＰＦ）試薬があげられる。ＡＰＦ試薬は、次亜塩素酸に対して高い反応性を持ち、酸化により蛍光化合物を生成する。
また、他の実施形態において、次亜塩素酸濃度を計測するシステムは、例えば、被処理空間内のガス状及び／または霧状の次亜塩素酸水を採取する容器を有する次亜塩素酸水採取部及び容器内に収容された純水を含む次亜塩素酸水採取部と、容器から回収した純水中の有効塩素濃度を計測する有効塩素濃度計とを含むことができる。 An example of a fluorescent reagent used is aminophenylfluorescein (APF) reagent. The APF reagent has high reactivity to hypochlorous acid and generates a fluorescent compound by oxidation.
In another embodiment, the system for measuring hypochlorous acid concentration is, for example, hypochlorous acid water having a container for collecting gaseous and / or mist-like hypochlorous acid water in the space to be treated. A hypochlorous acid water sampling unit including pure water contained in the sampling unit and the container, and an effective chlorine concentration meter for measuring the effective chlorine concentration in the pure water recovered from the container can be included.

使用される有効塩素濃度計として、ヨウ素吸光光度法またはＤＰＤ法を用い、回収した純水中の次亜塩素酸を反応により発色させて有効塩素濃度を計測し、有効塩素濃度に基づいて次亜塩素酸濃度を算出することができる。
次亜塩素酸濃度は、好ましくは５００ｐｐｂないし２００ｐｐｍにすることができる。 As the effective chlorine concentration meter used, iodine absorption photometry or DPD method is used, hypochlorous acid in the collected pure water is colored by reaction to measure the effective chlorine concentration, and hypochlorous acid is measured based on the effective chlorine concentration. The chloric acid concentration can be calculated.
The hypochlorous acid concentration can be preferably 500 ppb to 200 ppm.

５００ｐｐｂ未満であると、十分な殺菌効果が得られず、２００ｐｐｍを越えると装置や空間の金属が錆びやすくなる傾向がある。
実施形態に係る空間殺菌装置はまた、被処理空間内の空気を吸気する吸気装置、及び吸気装置と次亜塩素酸水供給部に接続され、吸気装置により導入された空気をガス状及び／または霧状の次亜塩素酸水を用いて殺菌する殺菌部をさらに含むことができる。 If it is less than 500 ppb, a sufficient sterilizing effect cannot be obtained, and if it exceeds 200 ppm, the metal in the device or space tends to rust.
The space sterilization apparatus according to the embodiment is also connected to the intake device that sucks air in the processing space, and the intake device and the hypochlorous acid water supply unit, and the air introduced by the intake device is gaseous and / or A sterilization part sterilized using a mist-like hypochlorous acid water can be further included.

図２に、吸気装置を備えた空間殺菌装置の構成の一例を表す模式図を示す。
図示するように、この空間殺菌装置は、吸気装置５１、次亜塩素酸水供給部５６、及び吸気装置５１と次亜塩素酸水供給部５６に接続された殺菌部５４、殺菌部５４に接続された排気部５７を含む。また、吸気装置５１前段には、任意に、粗い塵を取り除く除塵フィルタ５２を設けることができる。吸気装置５１は、吸気ダクト５８及び吸気ファン５３から構成される。殺菌部５４では、被処理空間から吸気装置５１により殺菌部５４に導入された空気をガス状及び／または霧状の次亜塩素酸水を用いて殺菌し、排気部５７を通して再び被処理空間に排出することができる。殺菌部５４内の次亜塩素酸濃度は、有効塩素濃度計やＡＰＦ試薬等により、計測することが可能であり、好ましくは５００ｐｐｂないし２００ｐｐｍにすることができる。５００ｐｐｂ未満であると、十分な殺菌効果を得ることができず、２００ｐｐｍを越えると平衡等により生じる腐食性ガスにより装置内の金属酸化により金属腐食が進み、装置寿命が短くなる傾向がある。 In FIG. 2, the schematic diagram showing an example of a structure of the space sterilizer provided with the intake device is shown.
As shown in the figure, this space sterilizer is connected to an intake device 51, a hypochlorous acid water supply unit 56, a sterilization unit 54 connected to the intake device 51 and a hypochlorous acid water supply unit 56, and a sterilization unit 54. The exhaust portion 57 is included. In addition, a dust removal filter 52 that removes coarse dust can be optionally provided upstream of the intake device 51. The intake device 51 includes an intake duct 58 and an intake fan 53. In the sterilization unit 54, the air introduced into the sterilization unit 54 from the space to be treated by the intake device 51 is sterilized using gaseous and / or mist-like hypochlorous acid water, and again enters the space to be treated through the exhaust unit 57. Can be discharged. The hypochlorous acid concentration in the sterilization unit 54 can be measured by an effective chlorine concentration meter, an APF reagent, or the like, and can be preferably 500 ppb to 200 ppm. If it is less than 500 ppb, a sufficient sterilizing effect cannot be obtained, and if it exceeds 200 ppm, metal corrosion proceeds due to metal oxidation in the apparatus due to corrosive gas generated due to equilibrium and the like, and the apparatus life tends to be shortened.

図３に、実施形態に使用可能な次亜塩素酸水供給部の一例を示す。
図示するように、次亜塩素酸水供給部１は、タンク１０と、配管１１と、ポンプ１２と、噴霧装置１３と、コントローラ１４と、を備えている。
タンク１０は、殺菌水の一例である次亜塩素酸水を貯水する。この次亜塩素酸水は、タンク１０が備える給水口を介して人手により、或いはタンク１０に接続された給水管を介してポンプなどの動力源により、適宜に補充される。 In FIG. 3, an example of the hypochlorous acid water supply part which can be used for embodiment is shown.
As illustrated, the hypochlorous acid water supply unit 1 includes a tank 10, a pipe 11, a pump 12, a spray device 13, and a controller 14.
The tank 10 stores hypochlorous acid water which is an example of sterilizing water. The hypochlorous acid water is appropriately replenished manually by a water supply port provided in the tank 10 or by a power source such as a pump through a water supply pipe connected to the tank 10.

配管１１は、一端がタンク１０の例えば底面に接続されるとともに、他端が噴霧装置１３に接続されている。ポンプ１２は、タンク１０の次亜塩素酸水を噴霧装置１３に供給する送液装置として機能するものであり、配管１１に設けられている。ポンプ１２は、例えば回転数の可変制御により、噴霧装置１３に送る次亜塩素酸水の流量を調整することができる。なお、タンク１０から噴霧装置１３への次亜塩素酸水の送液は、水頭圧等を利用して行われても良い。この場合においては、例えば配管１１に開度が可変な電磁弁を設けることにより、噴霧装置１３に送る次亜塩素酸水の流量を調整することができる。   One end of the pipe 11 is connected to the bottom surface of the tank 10, for example, and the other end is connected to the spraying device 13. The pump 12 functions as a liquid feeding device that supplies hypochlorous acid water in the tank 10 to the spray device 13, and is provided in the pipe 11. The pump 12 can adjust the flow rate of hypochlorous acid water to be sent to the spraying device 13 by, for example, variable control of the rotation speed. In addition, the hypochlorous acid water feeding from the tank 10 to the spraying device 13 may be performed using a water head pressure or the like. In this case, for example, the flow rate of hypochlorous acid water sent to the spraying device 13 can be adjusted by providing the piping 11 with an electromagnetic valve having a variable opening degree.

噴霧装置１３は、吸気口１５ａ及び排気口１５ｂを有する筐体１５と、この筐体１５に収容された気化器１６及びファン１７と、を備えている。図３の例において、配管１１は筐体１５の内部に延び、気化器１６に接続されている。
気化器１６は、配管１１を介して供給される次亜塩素酸水を気化し、殺菌成分を空間に放出する。同時に、気化器１６は粒径が比較的小さいミストも発生する。また、ミストの発生を主目的としない気化の方式としては、例えば、超音波方式を採用することができる。この場合において、気化器１６は、配管１１を介して供給される次亜塩素酸水を溜める容器と、超音波によりこの容器に溜められた次亜塩素酸水を振動させ、液面から次亜塩素酸水のミストを発生させる超音波振動子と、を有している。その他にも、気化器１６により次亜塩素酸水を気化する方式としては、微細孔を有するノズルから次亜塩素酸水を放出することにより次亜塩素酸水を気化（霧化）する方式などを採用しても良い。さらに気化フィルタにファン等で風を当てる自然気化式がある。空間殺菌の場合には、対象物を濡らさずに殺菌することが好ましいため、発生するミスト量は少なく、かつ粒径が小さいことが望ましい。 The spray device 13 includes a housing 15 having an intake port 15 a and an exhaust port 15 b, and a vaporizer 16 and a fan 17 housed in the housing 15. In the example of FIG. 3, the pipe 11 extends into the housing 15 and is connected to the vaporizer 16.
The vaporizer 16 vaporizes hypochlorous acid water supplied via the pipe 11 and discharges a sterilizing component to the space. At the same time, the vaporizer 16 also generates mist having a relatively small particle size. In addition, as a vaporization method that does not mainly generate mist, for example, an ultrasonic method can be employed. In this case, the vaporizer 16 vibrates the hypochlorous acid water supplied through the pipe 11 and the hypochlorous acid water stored in the container by ultrasonic waves so that the hypochlorous acid water is vibrated from the liquid surface. An ultrasonic vibrator that generates mist of chloric acid water. In addition, as a method of vaporizing hypochlorous acid water by the vaporizer 16, a method of vaporizing (atomizing) the hypochlorous acid water by discharging the hypochlorous acid water from a nozzle having a fine hole, etc. May be adopted. In addition, there is a natural vaporization formula that applies a wind to the vaporization filter with a fan or the like. In the case of space sterilization, since it is preferable to sterilize an object without wetting it, it is desirable that the amount of mist generated is small and the particle size is small.

ファン１７は、気化器１６により生成された気化した次亜塩素酸水及びミストを筐体１５の外部に送り出す。具体的には、ファン１７の回転に伴って吸気口１５ａから筐体１５に空気が取り込まれ、この空気が気化器１６により生成された気化した次亜塩素酸水及びミストとともに排気口１５ｂから排出（噴霧）される。ファン１７の回転数の可変制御により、筐体１５の外部に噴霧する気化した次亜塩素酸水等の量を調整することができる。   The fan 17 sends the vaporized hypochlorous acid water and mist generated by the vaporizer 16 to the outside of the housing 15. Specifically, as the fan 17 rotates, air is taken into the housing 15 from the intake port 15a, and this air is discharged from the exhaust port 15b together with the vaporized hypochlorous acid water and mist generated by the vaporizer 16. (Sprayed). By variable control of the rotation speed of the fan 17, the amount of vaporized hypochlorous acid water or the like sprayed outside the housing 15 can be adjusted.

コントローラ１４は、例えば第１殺菌装置１の制御の中枢を担うプロセッサ、各種の設定条件やプロセッサが実行するコンピュータプログラムを記憶したメモリ、及び、各部に供給する電圧を生成する電源装置などを備えている。このコントローラ１４は、ポンプ１２、気化器１６、及びファン１７などを制御する。図３の例において、コントローラ１４には、表示灯或いはディスプレイなどの表示装置、ボタン或いはスイッチ等の入力装置、及びスピーカなどの音声出力装置を備える入出力装置１８が接続されている。   The controller 14 includes, for example, a processor that plays a central role in the control of the first sterilizer 1, a memory that stores various setting conditions and computer programs executed by the processor, a power supply device that generates voltages to be supplied to the respective units, and the like. Yes. The controller 14 controls the pump 12, the vaporizer 16, the fan 17, and the like. In the example of FIG. 3, an input / output device 18 including a display device such as an indicator lamp or a display, an input device such as a button or a switch, and an audio output device such as a speaker is connected to the controller 14.

このような気化した殺菌水（次亜塩素酸水）は、被処理空間の内壁を濡らさずに殺菌することができ、同時に発生する粒径の小さいミストが付着しても迅速に蒸発するため、被処理空間の内壁表面等を過度に濡らすことがない。したがって、水洗いなどに不向きな被処理物の殺菌に適している。   Such vaporized sterilizing water (hypochlorous acid water) can be sterilized without wetting the inner wall of the treated space, and at the same time, even if mist with a small particle size is attached, it quickly evaporates. The surface of the inner wall of the treated space is not excessively wetted. Therefore, it is suitable for sterilization of an object unsuitable for washing with water.

次亜塩素酸水は、例えば、塩化ナトリウム、塩化カリウム、あるいは無機塩化物を含む電解質水溶液の電気分解により得られる電解水を使用することができる。
次亜塩素酸水中の有効塩素濃度は、１０ないし２００ｐｐｍであることが好ましい。
次亜塩素酸水は、ｐＨ７以下であることが好ましい。 As the hypochlorous acid water, for example, electrolyzed water obtained by electrolysis of an aqueous electrolyte solution containing sodium chloride, potassium chloride, or inorganic chloride can be used.
The effective chlorine concentration in hypochlorous acid water is preferably 10 to 200 ppm.
The hypochlorous acid water preferably has a pH of 7 or less.

図２の空間殺菌装置は空間除臭装置として使用可能であり、また、図３の次亜塩素酸水供給部は空間除臭装置に適用可能である。
空間除臭装置として使用場合、次亜塩素酸水は、ｐＨ３ないし７であることが好ましい。

次亜塩素酸水の実際の噴霧量は、噴霧した前後の次亜塩素酸水の重量の差から求めた。
空間体積より処理時間当たりの理論空間噴霧量を求めた。 The obtained hypochlorous acid water was applied to the hypochlorous acid water supply part of this sterilizer 25, for example, and each was sprayed in sealed space for 2 hours.
The actual spray amount of hypochlorous acid water was determined from the difference in the weight of hypochlorous acid water before and after spraying.
The theoretical space spray amount per processing time was calculated from the space volume.

それぞれ３０分、１時間、２時間後のシャーレ内の蛍光発光強度を図示しない分光蛍光光度計を用いて計測した。計測結果より、３０分、１時間、２時間後のシャーレ上に落下した次亜塩素酸水の量を算出した。
さらに、噴霧後、シャーレ直上に浮遊する次亜塩素酸水の有無を確認するため、同一場所で２時間放置した。噴霧中及び噴霧後の次亜塩素酸水量の和を、処理時間内にシャーレ直上の円柱の体積上に到達した次亜塩素酸水量として算出し、これを次亜塩素酸の空間存在量すなわち次亜塩素酸の濃度とした。 The fluorescence emission intensity in the petri dish after 30 minutes, 1 hour, and 2 hours was measured using a spectrofluorometer not shown. From the measurement results, the amount of hypochlorous acid water dropped on the petri dish after 30 minutes, 1 hour, and 2 hours was calculated.

図５は、気化式装置でｐＨ３の有効塩素濃度５０ｐｐｍの次亜塩素酸水を噴霧した時の重量変化から求めた理論空間噴霧量と、補足された次亜塩素酸との量との関係を表すグラフ図を示す。 The emission intensity was measured using an RF-5300PC manufactured by Shimadzu Corporation as a spectrofluorometer at an excitation wavelength of 490 nm and a fluorescence wavelength of 526 nm. The calibration curve was obtained from the emission intensity of hypochlorous acid water having a known concentration directly added to a reagent 5000 times that of APF.

Moreover, spraying can be performed at regular intervals even if it is not continuous, depending on the desired space abundance.

その時のオクラ表面の一般細菌を綿棒で採取して、標準寒天培地に移し、３７℃のインキュベータ内で２４時間培地培養した。

同様にｐＨ３の次亜塩素酸水においても実験を行った。この結果を下記表１に示す。 Moreover, when the space abundance of effective hypochlorous acid exceeded 500 ppm, the chlorine gas monitor showed 0.5 ppm.
Similarly, an experiment was conducted with hypochlorous acid water having a pH of 3. The results are shown in Table 1 below.

これにおいても４００ｐｐｂ以上で殺菌効果がみられた。
なお、図９に、実施例１に使用可能な２隔壁３室型の電解水生成装置の一例を表す概略図を示す。
図示するように、この電解水生成装置１５０は、陽極室１５４と、陰極室１５５と、陽極室１５４及び陰極室１５５の間に設けられた中間室１５１との３室からなる３室型電解槽１５８を有する。中間室１５１は、無機塩化物を含む電解質水溶液として飽和食塩水１６５とその無機塩化物である残留塩１６６とを収容する飽和食塩水貯留器１６１、塩水循環ポンプ１６２、及び食塩水供給ライン１６９を備えた飽和食塩水循環システム１６３と接続され、常にほぼ飽和状態の食塩水１６５が供給される。一方、陽極室１５４及び陰極室１５５は、給水システム１６４と接続され、各々、常に新しい水が供給される。中間室１５１と陽極室１５４の間は陰イオン交換膜１５２で仕切られ、中間室１５１と陰極室１５５の間は陽イオン交換膜１５３で仕切られている。陽極室１５４には陽極電極１５６、陰極室１５５には陰極電極１５７が備えられており、それぞれにプラスとマイナスの電圧が印加されている。 Even in this case, the bactericidal effect was observed at 400 ppb or more.
In addition, in FIG. 9, the schematic showing an example of the 2 partition 3 chamber type electrolyzed water generating apparatus which can be used for Example 1 is shown.
As shown in the figure, this electrolyzed water generating apparatus 150 includes a three-chamber electrolytic cell comprising an anode chamber 154, a cathode chamber 155, and an intermediate chamber 151 provided between the anode chamber 154 and the cathode chamber 155. 158. The intermediate chamber 151 includes a saturated saline reservoir 161 that stores a saturated saline solution 165 and a residual salt 166 that is the inorganic chloride as an aqueous electrolyte solution containing inorganic chloride, a salt water circulation pump 162, and a saline solution supply line 169. It is connected to the provided saturated saline circulation system 163, and a substantially saturated saline solution 165 is always supplied. On the other hand, the anode chamber 154 and the cathode chamber 155 are connected to the water supply system 164 and are always supplied with fresh water. The intermediate chamber 151 and the anode chamber 154 are partitioned by an anion exchange membrane 152, and the intermediate chamber 151 and the cathode chamber 155 are partitioned by a cation exchange membrane 153. The anode chamber 154 includes an anode electrode 156, and the cathode chamber 155 includes a cathode electrode 157, to which positive and negative voltages are applied, respectively.

陽極室１５４では、中間室１５１中の塩素イオンが陽極電極１５６に引っ張られ、陰イオン交換膜１５２を通過して陽極室１５４に移動し、陽極電極１５６で電子を渡して塩素ガスとなり、水と反応して次亜塩素酸と塩酸を生じる。次亜塩素酸と塩酸を含む酸性電解水は、酸性電解水に溶解できない塩素ガスと共に酸性電解水ライン１６７を通して取り出される。   In the anode chamber 154, the chlorine ions in the intermediate chamber 151 are pulled by the anode electrode 156, pass through the anion exchange membrane 152, move to the anode chamber 154, pass electrons to the anode electrode 156, become chlorine gas, Reacts to produce hypochlorous acid and hydrochloric acid. The acidic electrolyzed water containing hypochlorous acid and hydrochloric acid is taken out through the acidic electrolyzed water line 167 together with chlorine gas that cannot be dissolved in the acidic electrolyzed water.

陰極室１５５では、中間室１５１中のナトリウムイオンが陰極電極１５７に引っ張られ、陽イオン交換膜１５３を通過して陰極室１５５に移動し、陰極電極１５７で水が分解した水素イオンが電子を受け取って水素ガスとなり、水酸化ナトリウムを生じる。この水酸化ナトリウムの水溶液は、アルカリ性電解水として、アルカリ性電解水ライン１７１を通して取り出される。   In the cathode chamber 155, sodium ions in the intermediate chamber 151 are pulled by the cathode electrode 157, pass through the cation exchange membrane 153, move to the cathode chamber 155, and hydrogen ions whose water is decomposed at the cathode electrode 157 receive electrons. Into hydrogen gas, producing sodium hydroxide. This aqueous solution of sodium hydroxide is taken out through an alkaline electrolyzed water line 171 as alkaline electrolyzed water.

なお、実施形態に使用される無機塩化物として例えば塩化ナトリウム、及び塩化カリウムなどがあげられ、この場合、アルカリ性電解水としては、各々、水酸化ナトリウム水溶液、及び水酸化カリウム水溶液が得られる。
実施例２
実施例２では、蛍光試薬以外の試薬を使用して次亜塩素酸の空間存在量を算出し、除臭効果としてメチルメルカプタンのガス分解性能を評価した。 Examples of the inorganic chloride used in the embodiment include sodium chloride and potassium chloride. In this case, as the alkaline electrolyzed water, a sodium hydroxide aqueous solution and a potassium hydroxide aqueous solution are obtained, respectively.
Example 2
In Example 2, the space abundance of hypochlorous acid was calculated using a reagent other than the fluorescent reagent, and the gas decomposition performance of methyl mercaptan was evaluated as a deodorizing effect.

まず、１ｍ３の実験用ブースを用意する。
この実験用ブースの中に、次亜塩素酸水供給部として音波噴霧機、例えばシャーレなどの次亜塩素酸水採取部、及び有効塩素濃度計を含む空間防臭装置が設けられている。
例えば実験用ブース中にメチルメルカプタンガス１００ｐｐｍ／Ｎ２を一定量注入し、ブース内のメチルメルカプタン濃度を３ｐｐｍに設定した。さらに、ブース内に株式会社ＣＧＩ製超音波噴霧機エリアクリンＣＳ−Ｐ１０２を設置し、次亜塩素酸水を噴霧した。次亜塩素酸水の空間濃度によるメチルメルカプタンガスの分解量を測定した。 First, a laboratory booth of 1m 3.
In this experimental booth, a hypochlorous acid water supply unit is provided with a sonic sprayer, a hypochlorous acid water sampling unit such as a petri dish, and a space deodorizer including an effective chlorine concentration meter.
For example, a certain amount of methyl mercaptan gas 100 ppm / N 2 was injected into the experimental booth, and the methyl mercaptan concentration in the booth was set to 3 ppm. Furthermore, CGI Corporation ultrasonic sprayer Area Clean CS-P102 was installed in the booth and sprayed with hypochlorous acid water. The amount of methyl mercaptan gas decomposed by the spatial concentration of hypochlorous acid water was measured.

メチルメルカプタンガスの濃度はガステック製気体採取器ＧＶ−１１０を用い、同社製ガス検知管Ｎｏ．７０Ｌ（メルカプタン類検知管）にて測定した。空間濃度はシャーレ上に２０ｍｌの水を入れ、一定時間後にシャーレを取り出し、その水の有効塩素濃度を柴田化学製ＡＱＵＡＢ ＡＱ−１０２を用いヨウ素試薬吸光光度法により測定し、そのデータよりブース内の次亜塩素酸濃度を求めた。   The concentration of the methyl mercaptan gas was measured by using a gas sampling device GV-110 manufactured by Gastec Co., Ltd. It was measured with 70 L (mercaptan detector tube). As for the spatial concentration, 20 ml of water was put on the petri dish, and the petri dish was taken out after a certain period of time. Hypochlorous acid concentration was determined.

有効な次亜塩素酸の空間存在量に対するメチルメルカプタンのガス分解量(初期ガス濃度−ガス残存量)との関係を表すグラフ図を図１０に示す。
図中、８３がｐＨ３，８４がｐＨ６のときのメチルメルカプタン分解性能を表す。
図示するように、空間内のＨＣｌＯ濃度に比例してガスが分解され、またその比率が１：１であることがわかる。 FIG. 10 is a graph showing the relationship between the amount of gas decomposition of methyl mercaptan (initial gas concentration−residual amount of gas) with respect to the effective space abundance of hypochlorous acid.
In the figure, 83 represents the methyl mercaptan decomposition performance when pH 3 and 84 are pH 6.
As shown, the gas is decomposed in proportion to the HClO concentration in the space, and the ratio is 1: 1.

実施例２ではヨウ素試薬を用いて次亜塩素酸の空間存在量を算出し、メチルメルカプタンのガス分解性能を評価したが、実施例１に示すように蛍光試薬を用いて同様の評価を行うことも可能である。
実施例３
殺菌空間においた対象物は、その表面が殺菌されるが、その殺菌力は殺菌空間の殺菌濃度、殺菌処理時間、殺菌対象物（菌種類と数（密度）など）にて規定される。 In Example 2, the space abundance of hypochlorous acid was calculated using an iodine reagent and the gas decomposition performance of methyl mercaptan was evaluated. As shown in Example 1, the same evaluation should be performed using a fluorescent reagent. Is also possible.
Example 3
The surface of the object in the sterilization space is sterilized, but the sterilization power is defined by the sterilization concentration of the sterilization space, the sterilization treatment time, and the sterilization target (bacterial type and number (density), etc.).

図１１は、オクラの表面に着床した灰色かび病菌を殺菌対象物とした場合の、殺菌濃度と、その濃度にて必要な殺菌処理時間との関係を示している。
グラフ９０の横軸は、単位面積当たりに単位時間供給される次亜塩素酸ドライミスト供給量μｇ／（ｍ２・分）を表している。次亜塩素酸ドライミスト供給量は、活性酸素検出用蛍光試薬(Aminophenyl Fluorescein)、通称ＡＰＦ液を用いた蛍光強度測定法より算出できる。 FIG. 11 shows the relationship between the bactericidal concentration and the bactericidal treatment time required at that concentration when the gray mold fungus that has landed on the surface of okra is used as the sterilization target.
The horizontal axis of the graph 90 represents the hypochlorous acid dry mist supply amount μg / (m 2 · min) supplied per unit area per unit time. The amount of hypochlorous acid dry mist supplied can be calculated by a fluorescence intensity measurement method using a fluorescent reagent for detecting active oxygen (Aminophenyl Fluorescein), commonly called an APF solution.

ここでは、ＡＰＦ液で満たしたφ８４ｍｍのシャーレを所定の濃度の次亜塩素酸水のドライミストを噴霧空間に一定時間設置後に、回収したシャーレ内のＨＣＬＯ量から、単位面積・単位時間あたりの対象物への次亜塩素酸ドライミスト供給量を算出する。
一方で、縦軸は、殺菌処理時間を示しており、任意のドライミスト供給量に対して、対象を十分に殺菌するために必要な処理時間を示している。例えば条件（１）として１００（ｍｇ／ｌ）の濃度の次亜塩素酸水を用いた、次亜塩素酸ドライミスト供給量が５３μｇ／（ｍ２・分）の噴霧空間では、１．３時間（８０分）処理すれば対象物を殺菌できることを示している。実際に条件（１）で殺菌した場合、オクラ表面に３００万個いた灰色かび病菌が７０００個まで減少し、その後に２０℃にて一週間保管しても菌の発病がない事を確認している。一方で、殺菌処理無しのサンプルでは、同保管条件にて１週間後には灰色かび病菌の発病が観測される。 Here, the target per unit area / unit time is calculated from the amount of HCLO in the collected petri dish after a certain amount of dry hypochlorous acid water dry mist is placed in the spray space for a certain period of time in a petri dish filled with APF. Calculate the amount of hypochlorous acid dry mist supplied to the product.
On the other hand, the vertical axis indicates the sterilization processing time, and indicates the processing time required to sufficiently sterilize the target with respect to an arbitrary dry mist supply amount. For example, in a spray space using hypochlorous acid water having a concentration of 100 (mg / l) as the condition (1) and having a hypochlorous acid dry mist supply amount of 53 μg / (m 2 · min), 1.3 hours (80 minutes) It shows that an object can be sterilized by processing. When sterilized under condition (1), 3 million gray molds on the okra surface were reduced to 7000, and after that, even if stored at 20 ° C for 1 week, it was confirmed that there was no bacterial disease. Yes. On the other hand, in the sample without sterilization treatment, the occurrence of gray mold fungus is observed after 1 week under the same storage conditions.

また、オクラの表面積を１１３ｃｍ２と仮定して、ドライミスト供給量に表面積と処理時間を掛けた値がオクラ１本の表面に噴霧されたドライミストの総供給量となる。以下、ドライミスト総供給量（μｇ）とする。
条件（１）で殺菌処理した場合のオクラ１本に供給されたドライミスト総供給量は４８μｇとなる。 Further, assuming that the surface area of okra is 113 cm 2 , a value obtained by multiplying the dry mist supply amount by the surface area and the processing time is the total supply amount of dry mist sprayed on the surface of one okra. Hereinafter, the dry mist total supply amount (μg).
The total amount of dry mist supplied to one okra when sterilized under condition (1) is 48 μg.

また、条件（２）では、２５ｍｇ／Ｌの濃度の次亜塩素酸水を用いた、ドライミスト供給量７μｇ／（ｍ２・分）で、殺菌処理時間２４時間、条件（１）と同等の殺菌効果を得るためには総供給量１１２μｇと２倍以上のドライミスト総供給量が必要である。図１１ではグラフ９０の上の領域９１で殺菌効果がある。つまり殺菌効果は単純なドライミスト総供給量だけでは判断できず、瞬間的に供給する殺菌濃度が影響することがわかる。 Further, in condition (2), a dry mist supply amount of 7 μg / (m 2 · min) using hypochlorous acid water having a concentration of 25 mg / L is used, and sterilization treatment time is 24 hours, which is equivalent to condition (1). In order to obtain a sterilizing effect, a total supply amount of 112 μg and a dry mist total supply amount more than doubled are required. In FIG. 11, there is a sterilizing effect in the region 91 on the graph 90. In other words, it can be seen that the sterilizing effect cannot be judged only by a simple total amount of dry mist supplied, and the sterilizing concentration supplied instantaneously affects.

また、本例の灰色かび病菌は真菌であり、大腸菌などに代表される細菌は真菌の１／１０の殺菌力で殺菌できると言われているため、殺菌効果がある噴霧空間を図１２で定義する。
以上の結果から、殺菌処理時間y（時間）と次亜塩素酸ドライミスト供給量ｘ（μｇ／（ｍ２・分）との関係において、図１２のグラフ９２で表されるｙ＝１６．２１７ｘ−１．３８４以上の領域９３すなわち下記式（１）
ｙ≧１６．２１７ｘ−１．３８４…（１）
を満足するとき、殺菌効果がある噴霧空間とすることができる。 In addition, the gray mold fungus of this example is a fungus, and it is said that bacteria represented by Escherichia coli and the like can be sterilized with a sterilizing power 1/10 that of the fungus. To do.
From the above results, in the relationship between the sterilization treatment time y (hours) and the hypochlorous acid dry mist supply amount x (μg / (m 2 · min)), y = 16.217x represented by the graph 92 in FIG. −1.384 or more region 93, that is, the following formula (1)
y ≧ 16.217x− 1.384 (1)
When it satisfies, it can be set as the spray space which has a bactericidal effect.
