연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A multi-use sanitization system is disclosed which includes one or more containers in fluid communication with other system components. Components of the system include an ozone contacting device, such as a vortex-venturi or a sparger, for incorporating ozone into a liquid, an ozone generator to provide ozone to the vortex-venturi, a fluid transfer valve to allow simultaneous flow of liquid into and out of the container, and a pump to promote fluid flow through the system. Optionally, a gas-liquid separator with an optional integral gas release valve, an...

What is claimed is: 1. A sanitization system for producing ozonated liquid, the system comprising: a pump for circulating liquid through the system; a fluid transfer valve for interfacing with a liquid source to be ozonated, allowing simultaneous flow into and out of the system; an ozone generator for forming ozone to be incorporated into the liquid; and a vortex-venturi for incorporating ozone into the liquid by providing accelerated entry of liquid into the vortex-venturi prior to mixing with the ozone, the vortex-venturi comprising: an annular interior chamber with a central longitudinal axis, the annular interior chamber of the vortex-venturi having a widened initial section, a narrowed waist section with ozone entry ports positioned therein, and a widened mixed fluid outlet section from which ozonated liquid is released; and a liquid inlet positioned tangential to the widened initial section of the annular interior chamber for tangential entry of the liquid into the annular interior chamber; the tangential entry of the liquid inducing a vortex flow of the liquid within the annular interior chamber, the vortex flow having a center of rotation, and a low pressure zone being located in the center of rotation; the ozone generator being in fluid communication with the vortex-venturi to provide ozone to the ozone entry ports positioned in the narrowed waist section of the annular interior chamber providing the ozone to the liquid in the low pressure zone. 2. The system according to claim 1, wherein the liquid source is contained within a container, the container being in fluid communication with the pump through the fluid transfer valve. 3. The system of claim 2, wherein a plurality of removable containers having fluid transfer valves disposed therein are used interchangeably. 4. The system of claim 2 wherein the pump, the ozone generator, and the vortex-venturi are disposed within a base. 5. The system according to claim 4, wherein the container is a removable container, the fluid transfer valve being incorporated into the removable container, and liquid is circulated into and out of the container through the fluid transfer valve, the fluid transfer valve allowing the container to be removed from the base while preventing the liquid from leaking from the container when the container is not in place. 6. The system of claim 1 wherein the ozone generator comprises a corona discharge ozone generator. 7. The system according to claim 6, wherein the corona discharge ozone generator creates ozone using a high voltage/high frequency power supply, said corona discharge ozone generator comprising: an ozone generating chamber having open ends, and a high voltage electrode at each of the open ends; insulating end caps disposed at terminal ends of the chamber, the caps having gas ports formed therein in a direction tangential to the chamber, allowing for vortex flow through the generator; and a ground electrode comprising a metallic foil adhered to a dielectric material. 8. The system according to claim 1 additionally comprising an oxidation reduction potential (ORP) sensor in fluid communication with the system for detecting ozone level in the fluid. 9. The system according to claim 1, additionally comprising a gas-liquid separator downstream of the vortex-venturi for separating undissolved gasses from the ozonated liquid. 10. The system according to claim 9 additionally comprising an ozone destructor downstream of and in fluid communication with the gas-liquid separator, for destroying undissolved ozone gas arising from the gas-liquid separator. 11. The system according to claim 9, wherein the gas-liquid separator separates undissolved ozone gas using centrifugal force, the separator comprising: an inlet through which a gas-liquid mixture arising from the vortex-venturi enters under pressure; a channel following from the inlet; means to force the gas-liquid mixture under pressure into a vortex within the channel so as to generate a centrifugal force to move undissolved ozone gas to the center of the channel and liquid to the perimeter of the channel; a slot positioned around the inside of the channel through which a portion of the liquid is drawn off; an annular chamber in communication with the slot through which the liquid passes; and a gas release valve comprising a gas release port within the channel through which gas exits the channel. 12. The system according to claim 11 additionally comprising a float for interacting with liquid in the chamber to close the gas release port when the liquid level is high. 13. The system according to claim 1, additionally comprising a capacitor-coupled detector of high voltage and high frequency power supply to verify the supply of power to the ozone generator, the capacitor-coupled detector comprising: a first wire contacting a high voltage/high frequency lead to the ozone generator; a second wire in close proximity to the high voltage/high frequency lead to the ozone generator, capacitance being formed due to close proximity of the first wire and the second wire; and a detection circuit in communication with the second wire, for detecting the capacitance comprising a microprocessor and a monostable, to verify a supply of power to the ozone generator. 14. The system according to claim 13 wherein said detection circuit is powered by an external power source or through said capacitance. 15. The system according to claim 1 additionally comprising an oxidation reduction potential sensor comprising: a reference electrode made from silver or plated silver; an ORP sensing electrode made from platinum, plated platinum, gold or plated gold; an ORP sensor in fluid contact with the water path; and a continuously monitoring sensor that controls the process time. 16. The system according to claim 1 additionally comprising a pour-through filtration unit. 17. The system according to claim 1 wherein the fluid transfer valve is a check valve. 18. The system according to claim 1 wherein the fluid transfer valve is a double check valve. 19. The system according to claim 4, wherein the container is a removable container, the removable container comprises the fluid transfer valve, and liquid is circulated into and out of the container through the fluid transfer valve, the fluid transfer valve allowing the container to be removed from an interface with the base and preventing the liquid from leaking from either the base or the container when the container is not in place. 20. A vortex-venturi for incorporating a gas into a liquid, comprising: a cylindrical body with an annular interior chamber, a liquid inlet, a gas inlet, and a gas-liquid mixture outlet, the annular interior chamber having a helical path between the liquid inlet and the gas-liquid outlet; the annular interior chamber comprising a widened initial section decreasing in diameter to form a narrowed waist section of a substantially cylindrical configuration, and a widened outlet section expanding to an increasing diameter relative to the narrowed waist section, the narrowed waist section having gas entry ports positioned therein; wherein the liquid inlet is positioned tangential to the widened initial section; wherein the tangential entry of the liquid induces a vortex flow of the liquid within the annular interior chamber, the vortex flow having a center of rotation, and a low pressure zone being located in the center of rotation; and wherein the gas enters the annular interior chamber through the gas entry ports positioned in the narrowed waist section, the gas entry ports providing the gas to the liquid in the low pressure zone. 21. The vortex-venturi of claim 20, having one or more vanes formed in the annular interior chamber on a surface of the widened outlet section.
