Description

本発明は、浴槽等の循環水を殺菌処理する殺菌処理システム及び前記循環水の殺菌処理の制御方法に関する。 The present invention relates to a sterilization treatment system for sterilizing circulating water in a bathtub or the like, and a control method for sterilizing the circulating water.

プール及び浴槽水等の大腸菌・レジオネラ菌の殺菌については、人体への安全性の高い塩素殺菌が使用されてきたものの、細菌・ウイルスの耐性化や人体の抵抗力の変化等によって、充分な殺菌効果が望め無くなりつつある。 Chlorine sterilization, which is highly safe for the human body, has been used to sterilize E. coli and Legionella bacteria in pools and bathtub water. It is becoming less and less effective.

またオゾン殺菌はこれらの細菌・ウイルスに対しても十分な酸化力を有する一方、高濃度のオゾンは人体に悪影響を与える可能性があり、濃度調整を怠ることにより、安全性にもとる場合があった。 In addition, while ozone sterilization has sufficient oxidizing power against these bacteria and viruses, high concentrations of ozone may adversely affect the human body, and neglecting concentration adjustment may compromise safety. there were.

注入するオゾン濃度を制御する殺菌システムとして従来、オゾン処理後、被処理水の色度と大腸菌・大腸菌群数の関係から塩素注入率を決定する液体処理装置が開示される（特許文献１）。またほかに従来、微生物数に応じて塩素やオゾンの注入量を決定する消毒システムが開示される（特許文献２）。 As a sterilization system for controlling the concentration of ozone to be injected, conventionally, a liquid treatment apparatus is disclosed that determines the chlorine injection rate from the relationship between the chromaticity of the water to be treated and the number of coliforms and coliforms after ozone treatment (Patent Document 1). In addition, conventionally, a disinfection system is disclosed that determines the amount of chlorine or ozone to be injected according to the number of microorganisms (Patent Document 2).

しかしながら、上記従来のシステムのように菌濃度に基づいて塩素やオゾンの注入量を決定するものは、オゾンの高濃度化による危険性を確実に回避することができない。また、塩素殺菌とオゾン殺菌とを併用するシステムにおいて、塩素とオゾンを同時注入すると、両者が化学反応してしまい、塩素殺菌の殺菌効率、オゾン殺菌の殺菌効率の両方が低下してしまう。すなわち塩素殺菌とオゾン殺菌とを併用し同時使用することで、充分な殺菌効果を継続的に得ることができない事態が生じてしまう。 However, the above-described conventional system, which determines the amount of chlorine or ozone to be injected based on the bacteria concentration, cannot reliably avoid the danger caused by the high concentration of ozone. In addition, in a system using both chlorine sterilization and ozone sterilization, if chlorine and ozone are simultaneously injected, they chemically react, and both the sterilization efficiency of chlorine sterilization and the sterilization efficiency of ozone sterilization decrease. That is, by using both chlorine sterilization and ozone sterilization together, a situation arises in which a sufficient sterilization effect cannot be obtained continuously.

そこで本発明では、人体への安全性の高さを確保しつつ、充分な殺菌効果を継続的に得ることのできる殺菌システムを提供することを課題とする。 Accordingly, an object of the present invention is to provide a sterilization system capable of continuously obtaining a sufficient sterilization effect while ensuring a high degree of safety for the human body.

上記課題を解決すべく本発明では以下〔１〕～〔６〕の手段を講じている。
まず、オゾン濃度に応じたオゾン殺菌→塩素殺菌の切り替えを行うことに関して、本発明の循環水殺菌システムは、
〔１〕浴槽９から循環水を流出させる流出管P2、及び、浴槽９に循環水を流入させる流入管P1を互いに管連通して形成される循環配管路と、
循環配管路のうち流出管P2の下流側に介設される循環ろ過装置（例えば集毛器８、濾過ポンプ１、及び濾過機２からなる）と、
循環配管路のうち循環ろ過装置の下流側に分岐接続されるオゾン注入装置（例えばオゾン発生装置３、オゾン注入管P3、エジェクター３Eからなる）と、
循環配管路のうちオゾン注入装置の下流側に介設される混合反応装置（例えばミキサー４、及び反応塔５からなる）と、
循環配管路のうち混合反応装置の下流側と流入管P1の上流側との間に分岐接続される薬注入装置（例えば薬発生装置７、及び三方電磁弁１１からなる）と、
浴槽９内又は流入管P1、並びに浴槽９内又は流出管P2にそれぞれ設けられた第一、第二のオゾンセンサS1、S2と、を具備してなる循環水殺菌システムであって、
第一、第二のオゾンセンサS1、S2はそれぞれ、浴槽循環水のオゾン濃度が第一設定値を超えた状態であるか、及び、第二設定値を下回った状態であるかを、所定の設定時間間隔で検知するものであり、
循環ろ過装置、オゾン注入装置、及び混合反応装置が動作しかつ薬注入装置が動作していない「オゾン注入動作」中において、第一、第二のオゾンセンサＳ１，Ｓ２のいずれかで第一設定値を超えた状態が検知された場合、
オゾン注入装置の動作を停止させて、循環ろ過装置、及び混合反応装置が動作しかつオゾン注入装置及び薬注入装置が動作していない「非注入動作」に切り替え、
前記「非注入動作」への切り替えののち、第一、第二のオゾンセンサＳ１，Ｓ２のいずれかで第二設定値を下回った状態が検知された時点にて、
循環ろ過装置、混合反応装置、及び薬注入装置が動作しかつオゾン注入装置が動作していない「薬注入動作」に切り替えることを特徴とする。 In order to solve the above problems, the present invention takes the following measures [1] to [6].
First, regarding switching from ozone sterilization to chlorine sterilization according to the ozone concentration, the circulating water sterilization system of the present invention
[1] A circulation pipeline formed by connecting an outflow pipe P2 for flowing out circulating water from the bathtub 9 and an inflow pipe P1 for flowing circulating water into the bathtub 9,
A circulation filtration device (for example, composed of a hair collector 8, a filtration pump 1, and a filter 2) interposed downstream of the outflow pipe P2 in the circulation pipeline;
an ozone injection device (for example, comprising an ozone generator 3, an ozone injection pipe P3, and an ejector 3E) branched and connected downstream of the circulation filtration device in the circulation pipeline;
a mixing reaction device (for example, comprising a mixer 4 and a reaction tower 5) interposed downstream of the ozone injection device in the circulation pipeline;
a drug injection device (for example, comprising a drug generator 7 and a three-way electromagnetic valve 11) branched and connected between the downstream side of the mixing reactor and the upstream side of the inflow pipe P1 in the circulation pipeline;
A circulating water sterilization system comprising first and second ozone sensors S1 and S2 provided in the bathtub 9 or in the inflow pipe P1 and in the bathtub 9 or in the outflow pipe P2, respectively,
The first and second ozone sensors S1 and S2 detect whether the ozone concentration of the circulating water in the bathtub exceeds the first set value or falls below the second set value, respectively. It detects at set time intervals,
During the "ozone injection operation" in which the circulation filtration device, the ozone injection device, and the mixing reaction device are in operation and the chemical injection device is not in operation, either the first or second ozone sensor S1 or S2 is set to the first setting. If an out-of-value condition is detected,
Stop the operation of the ozone injection device and switch to "non-injection operation" in which the circulation filtration device and the mixing reaction device are in operation and the ozone injection device and the drug injection device are not in operation,
After switching to the "non-injection operation", at the time when any of the first and second ozone sensors S1 and S2 is detected to be below the second set value,
It is characterized by switching to a "medicine injection operation" in which the circulation filtration device, the mixing reaction device, and the drug injection device are in operation and the ozone injection device is not in operation.

「オゾン注入動作」から「薬注入動作」へ直接移行するのではなく、一旦「非注入動作」に切り替えて循環水中のオゾン濃度が一定以下に下がってから薬注入を行うことで、オゾン混入による注入薬との化学反応を確実に抑制することができ、オゾンと薬注入との併用による非殺菌の時間を生じさせないものとしている。また、「非注入動作」中は水循環によって循環水中のオゾン濃度が徐々に下がっていくものの、雑菌の繁殖は一定のオゾン濃度を下回らない限り盛んにはならない。このため、第二設定値を雑菌の繁殖が抑えられるオゾン濃度に設定し、かつポンプによる水循環を継続させることで、「非注入動作」中も雑菌繁殖が盛んになることがない。つまり第二設定値をオゾン殺菌による雑菌繁殖の抑制効果が低くなる限界値に設定することで、オゾン殺菌による雑菌繁殖の抑制効果がなくなったタイミングで薬注入動作に切り替え、何も注入していない「非注入動作」を動作の切り替えの間に挟んでおきながら、殺菌力の高い状態を維持することができる。 Instead of switching directly from "ozone injection operation" to "medicine injection operation", by temporarily switching to "non-injection operation" and then injecting medicine after the ozone concentration in the circulating water drops below a certain level, The chemical reaction with the injection medicine can be reliably suppressed, and the non-sterilization time due to the combined use of ozone and medicine injection is not generated. Also, during the "non-injection operation", the water circulation causes the ozone concentration in the circulating water to gradually decrease, but the propagation of various bacteria does not become active unless the ozone concentration falls below a certain level. Therefore, by setting the second set value to an ozone concentration that suppresses the propagation of germs and continuing the water circulation by the pump, germs do not proliferate even during the "non-injection operation". In other words, by setting the second set value to a limit value at which the effect of suppressing the propagation of various bacteria by ozone sterilization is low, at the timing when the effect of suppressing the propagation of various bacteria by ozone sterilization is lost, the operation is switched to the medicine injection operation, and nothing is injected. A state of high sterilizing power can be maintained while sandwiching the "non-injection operation" between switching operations.

〔２〕或いは、前記「非注入動作」から「薬注入動作」への切り替えにおいては、
前記「オゾン注入動作」から「非注入動作」への切り替えののち、第一、第二のオゾンセンサＳ１，Ｓ２のいずれかで第二設定値を下回った状態が検知された場合、或いは前記切り替えから所定時間が経過した場合のうち、いずれかが先に発生した時点にて、循環ろ過装置、オゾン注入装置、及び混合反応装置が動作しかつ薬注入装置が動作していない「薬注入動作」に切り替えるものとしてもよい。 [2] Alternatively, in switching from the "non-injection operation" to the "medicine injection operation",
After switching from the "ozone injection operation" to the "non-injection operation", if any of the first and second ozone sensors S1 and S2 detects a state below the second set value, or the switching "Drug injection operation" in which the circulation filtration device, the ozone injection device, and the mixing reaction device are in operation and the drug injection device is not in operation at the time when any of the predetermined time has passed since may be switched to

「オゾン注入動作」から「非注入動作」への切り替えによって、循環配管内のオゾン濃度は水循環によって徐々に下がっていき、循環流量によって定まる所定時間の経過後には注入された薬が化学反応を起こさない程度となる。このような場合は、オゾン濃度がいずれかのセンサ接地箇所で第二設定値を下回らない場合であっても、注入された薬が化学反応を起こさない程度となる所定時間経過後には、自動的に薬注入動作に切り替える。これにより、注入薬を予め循環配管全体に行き渡らせ、「非注入動作」時における殺菌効果の低減時間を短くすることができる。 By switching from "ozone injection operation" to "non-injection operation", the ozone concentration in the circulation pipe gradually decreases due to the water circulation, and after the passage of a predetermined time determined by the circulation flow rate, the injected medicine causes a chemical reaction. to the extent that there is no In such a case, even if the ozone concentration does not fall below the second set value at any of the sensor grounding points, after a predetermined time has passed at which the injected medicine does not cause a chemical reaction, the switch to drug injection operation. As a result, the infusion medicine can be spread over the entire circulation pipe in advance, and the reduction time of the sterilization effect during the "non-injection operation" can be shortened.

また、バイパス配管路を含む３箇所でオゾン濃度測定を行うことに関して、本発明の循環殺菌システムは、
〔３〕前記流出管Ｐ２、流入管Ｐ１のそれぞれから分岐した分岐管同士が管連通してなり、循環配管路のうちオゾン注入部（例えばエジェクター３Ｅ）及び薬注入部（例えば三方電磁弁１１）の両方を含む注入管路区間をバイパスするバイパス配管路ＢＰ１と、
循環配管路の流通経路を、前記注入管路を通る循環経路と、前記バイパス配管路ＢＰ１を通るバイパス循環経路とに切り替えるバイパス切り替え装置と、
前記流出管Ｐ２及び流入管Ｐ１にそれぞれにそれぞれ設けられた第一、第二のオゾンセンサＳ１、Ｓ２と、
前記バイパス配管路に設けられた第三のオゾンセンサＳ３と、を具備してなり、
第一、第二、第三の各オゾンセンサＳ１，Ｓ２，Ｓ３でそれぞれオゾン濃度測定を所定時間間隔毎に行い、
循環ろ過装置（８，１，２）、オゾン注入装置（３）、及び混合反応装置（４，５）が動作しかつ薬注入装置（７）が動作していない「オゾン注入動作」中において、
第一、第二、第三のオゾンセンサＳ１，Ｓ２，Ｓ３のいずれかで第三設定値を超えた状態が検知された場合、
バイパス切り替え装置によって循環配管路の流通経路を、前記注入管路を通る循環経路から、前記バイパス配管路ＢＰ１を通るバイパス循環経路に切り替えると共に、
オゾン注入装置（３）の動作を停止させて、循環ろ過装置（８，１，２）、及び混合反応装置（４，５）が動作しかつオゾン注入装置（３）及び薬注入装置（４，５）が動作していない「非注入動作」に切り替えることが好ましい。 In addition, regarding the ozone concentration measurement at three locations including the bypass pipeline, the circulation sterilization system of the present invention is
[3] The branch pipes branched from the outflow pipe P2 and the inflow pipe P1 are connected to each other, and in the circulation pipe, an ozone injection part (e.g. ejector 3E) and a drug injection part (e.g. three-way electromagnetic valve 11) are provided. a bypass line BP1 that bypasses the injection line segment including both
a bypass switching device for switching a circulation route of the circulation pipeline between a circulation route passing through the injection pipeline and a bypass circulation route passing through the bypass pipeline BP1;
first and second ozone sensors S1 and S2 respectively provided in the outflow pipe P2 and the inflow pipe P1;
and a third ozone sensor S3 provided in the bypass pipeline,
Ozone concentrations are measured by the first, second, and third ozone sensors S1, S2, and S3 at predetermined time intervals,
During the "ozone injection operation" in which the circulation filtration device (8, 1, 2), the ozone injection device (3), and the mixing reaction device (4, 5) are in operation and the drug injection device (7) is not in operation,
When any of the first, second, and third ozone sensors S1, S2, and S3 detects a state exceeding the third set value,
A bypass switching device switches the circulation route of the circulation pipeline from the circulation route passing through the injection pipeline to the bypass circulation route passing through the bypass pipeline BP1,
The operation of the ozone injection device (3) is stopped, the circulation filtration device (8, 1, 2) and the mixing reaction device (4, 5) are operated, and the ozone injection device (3) and the chemical injection device (4, It is preferable to switch to "non-injection operation" where 5) is not operating.

〔４〕上記バイパス循環経路の切り替え及び非注入動作への切り替えの後であって、
第一、第二、第三のオゾンセンサＳ１，Ｓ２，Ｓ３のいずれかで第二設定値を下回った状態が検知された場合、或いは前記切り替えから所定時間が経過した場合のうち、いずれかが先に発生した時点にて、
バイパス切り替え装置によって循環配管路の流通経路を、前記バイパス配管路を通るバイパス循環経路から、前記注入管路を通る循環経路に切り替えると共に、
循環ろ過装置、オゾン注入装置、及び混合反応装置が動作しかつ薬注入装置が動作していない「薬注入動作」に切り替えるものとしてもよい。 [4] After switching the bypass circulation path and switching to non-injection operation,
When any one of the first, second, and third ozone sensors S1, S2, and S3 detects a state of being below the second set value, or when a predetermined time has passed since the switching, whichever occurs. When it happened earlier,
Switching a circulation route of the circulation pipeline from a bypass circulation route passing through the bypass pipeline to a circulation route passing through the injection pipeline by a bypass switching device,
It is also possible to switch to a "medicine injection operation" in which the circulation filtration device, the ozone injection device, and the mixing reaction device are in operation and the medicine injection device is not in operation.

バイパス循環経路の切り替えによって殺菌効果が落ちることを防止するために、オゾン濃度が第二設定値を下回った場合、或いは高濃度化による危険性が確実に回避される想定時間時間が経過した場合には、薬注入を行う循環経路に切り替えて薬注入殺菌を行うこととする。第二設定値としては、オゾン濃度が人体に悪影響を及ぼすことのない第一安全値を採用し設定することもできるし、オゾン濃度が薬注入に対して化学反応を起こすことのない第一安全値を採用し設定することもできる。 In order to prevent the sterilization effect from decreasing due to the switching of the bypass circulation route, when the ozone concentration falls below the second set value, or when the assumed time to reliably avoid the danger due to the high concentration has passed is switched to the circulation route for drug injection, and drug injection sterilization is performed. As the second setting value, it is possible to adopt and set the first safety value at which the ozone concentration does not adversely affect the human body, or the first safety value at which the ozone concentration does not cause a chemical reaction with the drug injection. A value can also be adopted and set.

「システム予定休止／停止時の一連動作」として、
循環ろ過装置、オゾン注入装置、及び混合反応装置が動作しかつ薬注入装置が動作していない「オゾン注入動作」中において、
予め設定されたシステムの予定休止時刻から所定時間だけ前の時刻になった場合、或いはシステム停止の指令を受けた（システム停止のスイッチが押された）場合、
他の装置を動作させたままさらに薬注入装置を動作させることで、循環ろ過装置、オゾン注入装置、薬注入装置、及び混合反応装置の全てが動作している「同時注入動作」に切り替え、
「同時注入動作」にてシステム休止前の所定時間が経過したのち、オゾン注入装置、循環ろ過装置、混合反応装置、及び薬注入装置の順に運転を停止して、「動作停止」の状態に切り替えることを特徴とする。 In addition, regarding the adjustment of the non-sterilization circulation operation time at the time of suspension / operation stop, the circulation sterilization system of the present invention
[5] A circulation pipeline formed by connecting an outflow pipe P2 for flowing out the circulating water from the bathtub 9 and an inflow pipe P1 for flowing the circulating water into the bathtub 9,
A circulation filtration device (for example, composed of a hair collector 8, a filtration pump 1, and a filter 2) interposed downstream of the outflow pipe P2 in the circulation pipeline;
an ozone injection device (for example, comprising an ozone generator 3, an ozone injection pipe P3, and an ejector 3E) branched and connected downstream of the circulation filtration device in the circulation pipeline;
a mixing reaction device (for example, comprising a mixer 4 and a reaction tower 5) interposed downstream of the ozone injection device in the circulation pipeline;

a recognition device that recognizes when a system pause or system restart command is received, or when operation is switched;
a timer that defines a scheduled system downtime, a scheduled system restart time, and a time before system downtime that is a predetermined time before the scheduled system downtime, and a timer that defines a predetermined time from each recognition time point of the recognition device. A circulating water sterilization system comprising
As a "series of actions during scheduled system pause/stop",
During the "ozone injection operation" in which the circulation filtration device, the ozone injection device, and the mixing reaction device are in operation and the drug injection device is not in operation,
When the time comes a predetermined time before the scheduled system shutdown time set in advance, or when a system shutdown command is received (the system shutdown switch is pressed),
By further operating the drug injection device while other devices are operating, switching to "simultaneous injection operation" in which all of the circulation filtration device, ozone injection device, drug injection device, and mixing reaction device are operating,
After a predetermined period of time before stopping the system in the "simultaneous injection operation", the operations of the ozone injection device, the circulation filtration device, the mixing reaction device, and the chemical injection device are stopped in this order, and switched to the "operation stop" state. It is characterized by

「オゾン注入動作」中におけるシステムの休止前の一連動作として、「オゾン注入動作」からそのまま動作停止するのではなく、一旦、オゾンと薬の両方を注入する「同時注入動作」に切り替え、その後、オゾン注入装置、薬注入装置の順に停止させることで、循環配管路に薬を残留させた状態でシステム停止することとなる。この薬の残留性により、システム再開時までの浴槽ないし循環配管内を減菌するか菌増殖を抑制することができる。但し、「同時注入動作」中はオゾン注入を行っており、化学反応により薬濃度が極めて低い状態となっている。また「同時注入動作」中は、化学反応によりオゾン濃度も低下しており、動作停止と共にオゾン濃度はほぼ０となる。動作停止の際は先にオゾン注入装置を停止し、その後の循環を経て最後に薬注入装置を停止させるため、停止直後は薬濃度が比較的高く、時間経過とともに薬濃度が徐々に低下する。なお、動作停止時間を外気温の低下時間帯に合わせることで、動作停止中の殺菌の繁殖を抑制することもできる。 As a series of operations before stopping the system during the "ozone injection operation", instead of stopping the operation as it is from the "ozone injection operation", once switch to the "simultaneous injection operation" to inject both ozone and medicine, and then By stopping the ozone injection device and the medicine injection device in this order, the system is stopped with the medicine remaining in the circulation pipeline. Due to the persistence of this medicine, it is possible to sterilize the inside of the bathtub or circulation pipe or suppress the growth of bacteria until the system is restarted. However, ozone is injected during the "simultaneous injection operation", and the drug concentration is extremely low due to the chemical reaction. Further, during the "simultaneous injection operation", the ozone concentration is also reduced due to the chemical reaction, and the ozone concentration becomes almost 0 when the operation is stopped. When the operation is stopped, the ozone injection device is stopped first, then circulation is performed, and finally the drug injection device is stopped. Therefore, the drug concentration is relatively high immediately after stopping, and the drug concentration gradually decreases with the passage of time. In addition, it is possible to suppress the propagation of sterilization during the operation stop time by adjusting the operation stop time to the period when the outside air temperature drops.

システム停止時は、経路内に薬が残留しており、そのまま定オゾンを注入開始しても、薬がオゾンと反応する間はオゾン殺菌の効果が低下してしまう。これに対応すべく、システムの休止状態から「オゾン注入動作」を開始する際の一連動作として、「動作停止」状態からそのまま「オゾン注入動作」へと移行するのではなく、一旦、オゾン注入とオゾンの混合反応のみを行って循環ろ過装置を動かさない「オゾン混合動作」に切り替えてから、その後、循環ろ過装置を起動させることとしている。これにより、オゾン濃度を或る程度まで高めた状態で循環配管路に一気にオゾン注入することとなる。高濃度化したオゾンによって注入開始直後からしばらくは残留薬との化学反応が起こり、残留薬の濃度が低下した状態となる。この状態中でも、高濃度化したオゾンの注入によってある程度のオゾン殺菌効果を得ることができる。 When the system is stopped, the medicine remains in the path, and even if constant ozone injection is started, the effect of ozone sterilization is reduced while the medicine reacts with ozone. In response to this, as a series of operations when starting the "ozone injection operation" from the system resting state, instead of moving directly from the "operation stop" state to the "ozone injection operation", once the ozone injection and After switching to the "ozone mixing operation" in which only the ozone mixing reaction is performed and the circulation filtration device is not moved, the circulation filtration device is started. As a result, ozone is injected into the circulation pipeline at once while the ozone concentration is increased to a certain extent. A chemical reaction with the residual drug occurs for a while immediately after the start of injection due to the ozone having a high concentration, and the concentration of the residual drug is lowered. Even in this state, a certain degree of ozone sterilization effect can be obtained by injecting highly concentrated ozone.

In order to obtain the effect, the system automatically switches from chemical sterilization (for example, chlorine sterilization) to ozone sterilization.

While being interposed and connected, the short distance sections near the upstream and downstream of the mixer 4 are partitioned by the flange F so as to be separable. Further, the medicine injection device 7 and the three-way solenoid valve 11 are branched and connected in the circulation pipe, and a short distance section including the first ozone sensor S1 is demarcated by a flange F so as to be separable. Further, a bypass pipe BP2 is provided by connecting the branch pipes of the three-way valve branched from each of the short-distance sections formed by these flanges F to each other. Incidentally, the bypass pipe BP2 is provided with a third ozone sensor S3 in the pipe, and the flow is controlled by a check valve and a gate valve (not shown). By forming a short-distance section with the flange F, it becomes possible to install it in an existing circulation route, and it becomes easy to perform replacement and maintenance. In this embodiment, as in Embodiment 1, sensors are interposed at the inlet and outlet of the circulation pipe to the bathtub 9, respectively, and the ozone generator and the filtration pump are interlocked according to the detection result of each sensor, and the ozone injection amount and the It is a system that mutually controls the circulation flow rate.

図３に示す本発明の実施例３のシステムは、複数の浴槽９Ａ，９Ｂ，９Ｃそれぞれへの分岐循環管の入口部、出口部それぞれにセンサＳ３Ａ，Ｓ３Ｂ，Ｓ３Ｃを介在させると共に、各分岐循環管の上流側である集合循環管にセンサＳ１を介在させており、センサの検出結果によってオゾン発生装置と薬注装置を連動させ、オゾン注入量と注入時間、及び、薬注量とを相互に制御するシステムとなっている。
センサは紫外線吸収測定器を用いることができる。この場合、溶存オゾン濃度、及び、微小な気相（オゾンバブル）濃度を検出する。 The system of Embodiment 3 of the present invention shown in FIG. A sensor S1 is interposed in the collection circulation pipe upstream of the pipe, and the ozone generator and the chemical injection device are interlocked according to the detection result of the sensor, and the ozone injection amount, injection time, and chemical injection amount are mutually controlled. It is a system to control.
An ultraviolet absorption measuring device can be used as the sensor. In this case, the dissolved ozone concentration and minute gas phase (ozone bubble) concentration are detected.

実施例３のシステムは、具体的には、複数の浴槽９Ａ，９Ｂ，９Ｃへの循環配管の流入管Ｐ１Ａ，Ｐ１Ｂ，Ｐ１Ｃそれぞれに第四センサＳ４Ａ，Ｓ４Ｂ，Ｓ４Ｃを介在させると共に、各センサの検出結果によってオゾン発生装置と濾過ポンプを連動させ、オゾン注入量と循環流量とを相互に制御するシステムとなっている。複数の浴槽９Ａ，９Ｂ，９Ｃそれぞれからの流出管Ｐ２Ａ，Ｐ２Ｂ，Ｐ２Ｃはホッパー９０Ｈからオーバーフロータンク９０内に貯水され、オーバーフロータンク９０のオーバーフロー排出先として設けられた流出管Ｐ２が循環配管として接続される。 Specifically, in the system of the third embodiment, fourth sensors S4A, S4B, and S4C are interposed in the inflow pipes P1A, P1B, and P1C of the circulation pipes to the plurality of bathtubs 9A, 9B, and 9C, respectively, and each sensor The ozone generator and the filtration pump are interlocked according to the detection result, and the ozone injection amount and the circulation flow rate are mutually controlled.

＜具体的な動作例＞
オゾン殺菌から薬（塩素）殺菌への切り替え例を以下にしめす。オゾン濃度センサからの信号にて、オゾン濃度が上限値0.05ｐｐｍを超えたとき又は、オゾン濃度が下限0.03ｐｐｍを超えたとき、専用制御装置にて塩素注入に切り替える。
＜システムの使用方法及び制御方法＞
システム停止・使用後薬（塩素）殺菌へタイマー注入（翌朝まで残留塩素で感染防止）
0.03ppm（0，01ppmＣＴ値）～0，05ppm オゾン殺菌0.01～0，05ｐｐｍ以外塩素に切り替わる。タイマー設定で、入浴ｔ時間はシステム装置運転でオゾン殺菌、入浴終了し、装置停止30分前に塩素が注入され浴槽に流し込まれた後、装置が停止する。 <Specific operation example>
An example of switching from ozone sterilization to chemical (chlorine) sterilization is shown below. When the ozone concentration exceeds the upper limit of 0.05 ppm or the lower limit of 0.03 ppm according to the signal from the ozone concentration sensor, the dedicated controller switches to chlorine injection.
<How to use and control the system>
Stopping the system and injecting a timer into chemical (chlorine) sterilization after use (prevention of infection with residual chlorine until the next morning)
0.03ppm (0, 01ppm CT value) ~ 0, 05ppm Ozone sterilization 0.01 ~ 0, 05ppm other than chlorine is switched. By setting the timer, the bathing t time is the time when the system device is operated for ozone sterilization, the bathing is finished, and 30 minutes before the device is stopped, chlorine is injected and poured into the bathtub, and then the device is stopped.

装置停止後は残留性の無いオゾンはすぐに消える一方、浴槽に流し込まれた残留塩素で装置停止中の浴槽の菌の増殖を防止して翌朝まで塩素の殺菌効果を発揮する。
本発明は特に、薬（塩素）殺菌とオゾン殺菌を時間差で平行使用することに特徴がある。すなわち、薬（塩素）殺菌度オソ゛ン殺菌を同時に行えば、薬（塩素）殺菌とオゾン殺菌は殺菌方法が異なる為、殺菌効果が作用して半減してしまう。本発明は薬（塩素）殺菌とオゾン殺菌を時間差で動作させるため、オゾン殺菌と薬（塩素）殺菌が理想的な形で実現できる。
次の運転開始はタイマーで装置運転再開しオゾン殺菌を開始する。2時間以上オゾン殺菌を行ってから入浴開始させる。 After the equipment is stopped, the non-residual ozone disappears immediately, while the residual chlorine poured into the bathtub prevents the growth of bacteria in the bathtub while the equipment is stopped, and the chlorine's sterilization effect is exhibited until the next morning.
The present invention is particularly characterized in that chemical (chlorine) sterilization and ozone sterilization are used in parallel with a time lag. That is, if chemical (chlorine) sterilization and ozone sterilization are performed at the same time, the sterilization effect is halved because the sterilization method differs between chemical (chlorine) sterilization and ozone sterilization. In the present invention, chemical (chlorine) sterilization and ozone sterilization are operated with a time difference, so ozone sterilization and chemical (chlorine) sterilization can be realized in an ideal form.
At the next start of operation, the operation of the device is restarted by a timer and ozone sterilization is started. Start bathing after performing ozone sterilization for at least 2 hours.

＜オゾン殺菌から薬（塩素）殺菌への自動的切り替え＞
循環水のオゾン濃度が0.03ppm以上0.05ppm以下の一定の領域を外れた場合、センター稼働で自動的に薬（塩素）殺菌に切り替わる。公衆浴場・プール等は薬（塩素）殺菌が義務つけられているが、レジオネラ菌・大腸菌等に対して、オゾン殺菌（システム方式）濃度が認可領域以外になった場合自動的に塩素に切り替わる。 <Automatic switching from ozone sterilization to chemical (chlorine) sterilization>
If the ozone concentration of the circulating water is out of a certain range of 0.03ppm to 0.05ppm, the center will automatically switch to chemical (chlorine) sterilization. Chemical (chlorine) sterilization is required for public baths and pools, but if the ozone sterilization (system method) concentration for Legionella bacteria, E. coli, etc. is outside the approved range, it will automatically switch to chlorine.

＜システム運用例＞
塩素とオゾンと同時殺菌すると、塩素＆オソ゛ン殺菌効果が異なる為、殺菌効果が半減してしまう。これを回避するためシステム停止・使用後薬（塩素）殺菌へタイマー注入することで、翌朝までの残留塩素による感染防止を図る。具体的には、0.03ppm（0，01ppmＣＴ値）～0，05ppm オゾン殺菌0.01～0，05ｐｐｍ以外塩素に切り替わる。またタイマー設定で、入浴ｔ時間はシステム装置運転でオゾン殺菌、入浴終了し、装置停止30分前に塩素が注入され浴槽に流し込まれた後、装置が停止する。装置停止後は残留性の無いオゾンはすぐに消えるものの、浴槽に流し込まれた残留塩素で装置停止中の浴槽の菌の増殖を防止して翌朝まで塩素の殺菌効果がある。このように、薬（塩素）殺菌とオゾン殺菌を時間差で平行使用することで、両システムの併用による悪影響を回避し適切な殺菌状態を維持することができる。
薬（塩素）殺菌度オソ゛ン殺菌を同時に行えば、薬（塩素）殺菌とオゾン殺菌は殺菌方法が異なる為、殺菌効果が作用して半減するところ、「非注入動作」ないし「バイパス配管路への切り替え動作」を一旦挟んで「オゾン注入動作」「塩素注入動作」時間差を設けることで、オゾン殺菌と薬（塩素）殺菌を実現することができる。 <System operation example>
Simultaneous sterilization with chlorine and ozone halves the sterilization effect because chlorine and ozone have different sterilization effects. In order to avoid this, the system is stopped and a timer is injected into the post-use chemical (chlorine) sterilization to prevent infection due to residual chlorine until the next morning. Specifically, 0.03 ppm (0,01 ppm CT value) to 0,05 ppm ozone sterilization 0.01 to 0,05 ppm other than chlorine. In addition, by setting a timer, the bathing time t will be sterilized with ozone in the operation of the system, the bathing will be completed, and chlorine will be injected and poured into the bathtub 30 minutes before the device is stopped, and then the device will be stopped. After the device is stopped, the non-residual ozone disappears immediately, but the residual chlorine that flows into the bathtub prevents the growth of bacteria in the bathtub while the device is stopped, and the chlorine has a sterilizing effect until the next morning. In this way, by using chemical (chlorine) sterilization and ozone sterilization in parallel with a time lag, it is possible to avoid the adverse effects of both systems and maintain an appropriate sterilization state.
Chemical (chlorine) sterilization level If ozone sterilization is performed at the same time, the sterilization effect is halved due to the different sterilization methods of chemical (chlorine) sterilization and ozone sterilization, so "non-injection operation" or "bypass piping route" Ozone sterilization and chemical (chlorine) sterilization can be realized by providing a time difference between the "ozone injection operation" and the "chlorine injection operation" with the "switching operation" intervening.

次の運転開始はタイマーで装置運転再開しオゾン殺菌開始。2時間以上オゾン殺菌を行ってから入浴開始可能状態とする。バイパス配管を含む複数箇所でオゾン濃度測定を行い、各箇所の値に応じてオゾン殺菌から薬（塩素）殺菌への切り替え時の重複（オーバーラップ）時間/非重複（オーバーラップ）時間を調節する。また、オゾン殺菌と薬（塩素）殺菌の交互運転における、時間・濃度比率を短時間高濃度から長時間低濃度に移行するように調節する。 At the next start of operation, the timer restarts operation of the device and starts ozone sterilization. Bathing can be started after performing ozone sterilization for 2 hours or more. Measure the ozone concentration at multiple locations including the bypass pipe, and adjust the overlapping (overlapping) time/non-overlapping (overlapping) time when switching from ozone sterilization to chemical (chlorine) sterilization according to the values at each location. . Also, in the alternate operation of ozone sterilization and chemical (chlorine) sterilization, the time/concentration ratio is adjusted so as to shift from high concentration for a short time to low concentration for a long time.

［システム型オゾン殺菌システム］
本発明の循環水殺菌システムは１本の循環配管ラインに介設されてなり、循環水を全量一括で殺菌する。オゾン発生装置３で生成された気相のオゾンが、注入管Ｐ３からエジェクタ３Ｅにて循環配管内に送り込まれ、ミキサ４を経て反応塔５に送られることで、マイクロバブル化し、かつ高濃度化した液相のオゾンとして循環水と均等に接触する。余剰オゾンは加熱処理で酸素へ変換させる環境に優しいシステムです。また、活性炭が不用なためコンパクトなシステムです。薬（塩素）殺菌と異なり、有機物の分解除去も良好で、細菌・ウィルスを殺滅し耐塩素細菌を作らないため、バイオフィルムを発生させない。これにより、循環システムのろ過機や配管内はいつも清潔に保たれる。 [System type ozone sterilization system]
The circulating water sterilization system of the present invention is interposed in one circulating piping line, and sterilizes the entire amount of circulating water at once. Vapor phase ozone generated by the ozone generator 3 is fed into the circulation pipe from the injection pipe P3 by the ejector 3E, and sent to the reaction tower 5 via the mixer 4, thereby forming microbubbles and increasing the concentration. It comes into contact with the circulating water evenly as ozone in a liquid phase. Excess ozone is an environmentally friendly system that converts it into oxygen by heat treatment. In addition, it is a compact system because activated carbon is not required. Unlike chemical (chlorine) sterilization, it is good at decomposing and removing organic matter, kills bacteria and viruses, and does not create chlorine-resistant bacteria, so it does not generate biofilms. This keeps the filters and pipes of the circulation system clean at all times.

［システム型オゾン殺菌の配管ライン及び浴槽の殺菌について（（薬（塩素）殺菌との比較））］
浴槽から反応塔へ入った処理水は反応塔内で飲料水レベルの水質に処理されるが、反応塔で生じた余剰オゾンは加熱処理で酸素へ返還され、反応塔から浴槽へ送水される処理水中の溶解中のオゾンは、人体へ影響の無い残留溶存オゾン0.05ppm以下＜ドイツDIN規格基準＞に設定しており、＜システムの場合0.02ppm～0.03ppm＞30分に1回の割合で浴槽とシステム内の反応塔を循環しており、常に新しい新鮮な水質を有するオゾン処理水が補給される。 [Sterilization of piping lines and bathtubs of system type ozone sterilization ((comparison with chemical (chlorine) sterilization))]
The treated water that enters the reaction tower from the bath is processed to the level of drinking water in the reaction tower, but the excess ozone generated in the reaction tower is returned to oxygen by heat treatment, and the water is sent from the reaction tower to the bath. Ozone dissolved in water is set to 0.05ppm or less <German DIN standards>, which has no effect on the human body. and the reaction tower in the system, and the ozonated water with fresh fresh water quality is always replenished.

薬（塩素）殺菌の場合は浴槽の中の残留塩素の濃度管理が基準＜レジオネラ属菌指針0.2ppm～0.4ppm＞とされているが、塩素管理は入浴者の人数等の条件で塩素濃度管理が異なって来るので、浴槽内やろ過機器の前や浴槽の直前等常に残留塩素濃度の確認が必要となる。しかし、システム型システムは基本的に反応塔の中で有機物の除去分解ならびにレジオネラ属菌などの最近の殺滅が行われ、反応塔以降も浴槽や配管には0.02ppm～0.03ppmの溶存オゾンが存在するため配管の洗浄作用等効果があり、新しい浴槽への入浴者の付体菌等は、30分に1回の対流作用で循環システムへ吸引口から吸い込まれ常時オゾン処理され続けるため、上記＜1000人以上使用した水も飲料水レベルの水質＞の水質が保証されることとなる。 In the case of chemical (chlorine) sterilization, the standard for controlling the concentration of residual chlorine in the bathtub is <0.2ppm to 0.4ppm for Legionella spp. Therefore, it is necessary to always check the residual chlorine concentration in the bathtub, in front of the filtration equipment, or just before the bathtub. However, the system type system basically removes and decomposes organic matter in the reaction tower and kills Legionella spp. Because it exists, it has effects such as washing the pipes, and the bacteria attached to the bathers in the new bathtub are sucked into the circulation system from the suction port by the convection once every 30 minutes and are continuously treated with ozone. Water quality of <water used by more than 1,000 people is at the same level as drinking water> will be guaranteed.

〈〈ろ過機・配管洗浄は不要〉
完全オゾン処理により菌の殺菌と同時に有機物が分解されるため、バイオフィルムの生成を抑制します。これによりろ過機内部、及び配管内壁へのバイオフィルムが付着せず、ろ過機・配管の洗浄作業が不要となる。 <<Filter and pipe cleaning not required>
Complete ozone treatment suppresses biofilm formation by sterilizing bacteria and decomposing organic matter at the same time. As a result, biofilms do not adhere to the inside of the filter and the inner walls of the pipes, eliminating the need to clean the filter and pipes.

〈気中オゾン濃度〉
通常、オゾンは危険であるという認識がありますが、システムシステムにおいて人体に悪影響を及ぼす程の高濃度オゾンが室内等に漏洩することはなく、気中のオゾン濃度は0.05ppm※1以下を維持するよう設定している。 <Atmospheric ozone concentration>
It is generally recognized that ozone is dangerous, but in the system, high-concentration ozone that adversely affects the human body will not leak indoors, etc., and the ozone concentration in the air will be maintained at 0.05ppm*1 or less. is set as follows.

〈水中オゾン濃度〉
水中にオゾンが溶け込むことでオゾン水となりますが、オゾンは人体に悪影響を与えるものではありません。しかし、システムシステムでは安全と利用者の安心を考慮し、水中溶存オゾン濃度が0.05mg／L以下になるよう設定している。 <Ozone concentration in water>
When ozone dissolves in water, it becomes ozonated water, but ozone does not adversely affect the human body. However, in consideration of safety and user's peace of mind, the system system is set so that the concentration of dissolved ozone in water is 0.05 mg/L or less.

（ろ過装置）
システムに入った浴槽水は、最初に「集毛器８」で2ｍｍ以上の毛髪、無機質物が捕集され、「ろ過ポンプ１」により「ろ過装置」に入る。ろ過装置は砂ろ過方式で、ろ過材にセラミック（粒子径φ0.6～1.4ｍｍ）を使用し長期に安定したろ過を確保する。 (filtration device)
The bathtub water entering the system first collects hairs of 2 mm or more and inorganic substances in the "hair collector 8" and enters the "filtration device" by the "filtration pump 1". Filtration equipment uses a sand filtration method, and ceramics (particle size φ0.6 to 1.4 mm) are used for the filter media to ensure long-term stable filtration.

（オゾン発生装置）
オゾン発生装置３は空気を原料とし窒素成分を吸着分離し、高純度のオゾンガスを発生する。オゾンガスは循環ラインの「高性能エジェクター」と「ミキサー」を通過し、発生量の80～90％を処理水に注入させてオゾンを溶解したオゾン水に変わる。残った10～20％のオゾンは、気体のままオゾン反応塔に処理水と共に入り、酸化効率を上げる助けとなる。 (ozone generator)
The ozone generator 3 uses air as a raw material, adsorbs and separates nitrogen components, and generates high-purity ozone gas. Ozone gas passes through the "high-performance ejector" and "mixer" in the circulation line, and 80-90% of the generated amount is injected into the treated water to turn it into dissolved ozone water. The remaining 10-20% of ozone enters the ozone reaction tower in gaseous form together with the treated water, helping to increase the oxidation efficiency.

（反応塔５）
「ろ過装置」で除去できなかった溶存有機物及び細菌類を含んだ全ての浴槽循環水は「反応塔５」を通過する。反応塔５では微細粒気体のオゾンを吸収し、水とオゾンが溶け込みあった状態に近い処理水は、「オゾン反応塔」の内部を旋回しながら水中の細菌類や油脂などの有機物を激しく酸化させて殺菌し、あるいは分解し飲用水と同等レベルの浄化処理水となる。 (Reaction tower 5)
All of the bath circulating water containing dissolved organic matter and bacteria that could not be removed by the "filter" passes through the "reaction tower 5". In the reaction tower 5, the ozone of the fine particle gas is absorbed, and the treated water, which is almost in a state where water and ozone are dissolved, circulates inside the "ozone reaction tower" and violently oxidizes organic matter such as bacteria and oil in the water. It is sterilized by drying, or decomposed to become purified water of the same level as drinking water.

（排オゾン処理）
「反応塔５」で殺菌や有機物の分解などの作業が済んだ後、処理水に吸収されていたオゾンはほとんど酸化に消費され残っていないものの、気体のまま残った微かなオゾンはオゾン反応塔の上部の排オゾンスペースに集められ、塔外に導かれて「気液分離器（ドレンセパレータ）」で水分を除いた後、セラミックヒーターの「排オゾン処理装置」により加熱（350℃以上）処理し、酸素に分解し空気中に放出する。 (exhaust ozone treatment)
After sterilization and decomposition of organic matter in "reaction tower 5", most of the ozone absorbed in the treated water is consumed by oxidation and hardly remains. Collected in the exhaust ozone space at the top of the tower, it is led out of the tower, and after removing moisture with a "gas-liquid separator (drain separator)", it is heated (350 ° C or higher) by a ceramic heater "exhaust ozone treatment device". decomposes into oxygen and released into the air.

（循環ろ過システムの停止時、起動時）
１日のシステム停止の約30 分前より、塩素注入装置を作動させ、夜間等システムの停止中に塩素によって浴槽内での細菌の殺菌、増殖の防止を行う。薬注入時間を設けることで、残留薬剤濃度により菌の減菌、増殖防止を図る。循環浄化装置運転時間と塩素注入時間は、制御盤１０においてタイマーで設定されている。循環浄化装置運転中はオゾン殺菌を実施し、1 日の循環機運転停止前に薬注ポンプによってタイマーにより15～30
分間前後自動注入され、塩素の残留性により翌朝の運転開始まで浴槽水の減菌及び増殖を防止する。なお、循環浄化装置運転中はオゾン殺菌を行っているため、塩素濃度はほとんどない。塩素注入直後の濃度は比較的濃く(約0.2～0.4mg/L)、翌朝にかけて濃度は低下する。 (When stopping or starting the circulation filtration system)
About 30 minutes before the system is shut down for the day, the chlorine injection device is activated, and during the night when the system is shut down, chlorine kills bacteria in the bathtub and prevents their growth. By setting the drug injection time, the residual drug concentration is used to sterilize and prevent the growth of bacteria. The operation time of the circulation purification device and the chlorine injection time are set by a timer on the control panel 10 . Ozone sterilization is carried out while the circulation purifier is in operation, and a timer is used for 15 to 30 minutes with a chemical injection pump before stopping the circulator operation for the day.
It is automatically injected before and after every minute, and the residual chlorine prevents sterilization and growth of the bathtub water until the operation starts the next morning. Since ozone sterilization is performed during operation of the circulation purification system, there is almost no chlorine concentration. The concentration immediately after chlorine injection is relatively high (approximately 0.2-0.4mg/L), and the concentration decreases over the next morning.

（オゾン濃度の測定）
通常、システムシステムにおいてはオゾンが室内等へ漏洩しない仕組みになっているものの、万が一、オゾン発生器等に故障が生じた場合など予測のできない事態に陥った場合は、オゾンが漏洩する可能性は否定できない。このため、第一、第二、第三のオゾンセンサＳ１，Ｓ２，Ｓ３において第三設定値を設定すると共に、第四センサＳ４，第五のオゾンセンサＳ５で液中内指揮中のオゾン濃度を一定時間間隔毎に測定し異常監視を行っている。 (Measurement of ozone concentration)
Normally, the system is designed to prevent ozone from leaking into the room, etc. However, in the unlikely event that an ozone generator, etc. breaks down, there is a possibility of ozone leaking. Undeniable. Therefore, the first, second, and third ozone sensors S1, S2, and S3 are set to third set values, and the fourth and fifth ozone sensors S4 and S5 are used to measure the ozone concentration in the liquid. Measurements are taken at regular time intervals to monitor for abnormalities.
