Description

  The present invention generally relates to a sanitization system and the individual components of the system.

This application claims priority to US Patent Application No. 60 / 438,986, filed January 10, 2003, and US Patent Application No. 60 / 482,519, filed June 26, 2003. And have the right to enjoy the benefits. All of these patent applications are incorporated herein by reference.
Microbial contamination is the leading cause of illness. Bacteria and viruses are present in water, food and surfaces. There are currently several different techniques that can be utilized to eliminate and / or reduce microbial growth. However, the effectiveness of each method depends on the type of material being handled and the microorganisms present. In addition, chemical agents have a detrimental effect on human health, either alone or through by-products generated during the sanitization process.

  Tough chemicals can sanitize the surface, but they can have a stiff odor and a corrosive effect on the user's skin, making them unacceptable for sanitizing food.

  U.S. Pat. No. 4,173,051 to Raid discloses a vegetable washer that uses a paddle to stir and wash vegetables, but is prepared to reduce bacteria. Absent.

  U.S. Pat. No. 5,927,304 to Wen discloses a food washer that uses vibration to remove soil and uses ultraviolet light to kill bacteria.

  There is a need for a sanitization system that allows multiple sanitization or disinfection applications. There is a need for a consumer safe method of sanitizing or disinfecting water economically, on-site, and in a single unit. Furthermore, food, vegetables, plants, and surfaces that many people come into contact with regularly will benefit from an effective sanitization system that does not use hazardous chemicals.

  As used herein, the term sanitization means removing at least some of the undesirable components from substances such as liquids such as water or solids such as objects, surfaces or foods. To do. When used in connection with water or other liquids, the term purification is used interchangeably with the term sanitization herein. As used herein, the term disinfection means a high degree of sanitization, either liquid or solid. At the level of disinfection, the majority of live bacteria, viruses and / or other infectious pathogens are removed from the liquid or solid. However, disinfection is an advanced form of sanitization and is not used interchangeably with the term sterilization, which implies a more complete process than disinfection.

  Water ozonization

Ozone (O ₃ ) is a strong oxidant and is widely used as a food and water disinfectant. Examples include U.S. Patent No. 6,171,625 to Denver et al., U.S. Patent No. 6,200,618 to Smith et al., And U.S. Patent No. 6,485, to Audi et al. There is 769. However, these systems are large industrial systems and cannot prevent recontamination before delivery to the consumer.

  US Pat. No. 6,391,191 to Conrad discloses a domestic water treatment device that uses ozone to disinfect water.

  US Pat. No. 5,460,705 (Murphy et al.), US Pat. No. 5,770,033 (Murphy et al.), And US Pat. No. 5,989,407 (Andrews et al.) An apparatus that can be used is disclosed. The ozone so produced can be used to ozonize water.

  Vortex-venturi device

  Important prior art documents characterizing the field of vortex-venturi devices include US Pat. No. 4,123,800 granted to Mazzei, US Pat. No. 4,931,225 granted to Chen, U.S. Pat. No. 5,061,406, U.S. Pat.No. 5,302,325 to Chen, U.S. Pat. No. 5,863,128 to Mazei, U.S. Pat. No. 5,880,378 and US Pat. No. 5,893,641 to Garcia.

  The dispersion of one fluid into another is an important feature of a wide variety of operations. For example, gases are dispersed in a liquid for use in dissolving a large number of gases, gas-liquid reactions, and gas stripping of dissolved gases. The gas is also mixed with the gas. Liquids are also dispersed in other liquids for dilution or for liquid-liquid reactions. Examples include the incorporation of disinfectants or fertilizers into the water.

  Many devices have been developed to disperse one fluid (added fluid) into another fluid (main fluid). The purpose of such a device is to bring a balanced amount of one fluid into contact with the other fluid. In addition to this fluid metering, it is desirable that the added fluid be well dissolved and dispersed in the main fluid. When the additive fluid is a gas, the efficiency of dissolution depends on the size and movement of the bubbles. Vigorous movement of small bubbles promotes gas dissolution. Vigorous movements also help mix liquids.

  For example, U.S. Pat. No. 4,931,225 issued to Chen discloses a method and apparatus for dispersing gas in a liquid. The gas is injected into the liquid upstream of the venturi. The gas-liquid mixture then flows through the venturi and is accelerated to supersonic speed and then decelerated to subsonic speed. The resulting shock wave crushes and disperses the gas bubbles.

  US Pat. No. 5,061,406 to Chen discloses a method for dispersing gas in a liquid using an adjustable conical mixer to control the flow of the gas / liquid mixture to the venturi device. Yes. The conical mixer forms an annular opening in the venturi and controls the size of the opening. The gas is injected at supersonic speed upstream of the venturi. The gas / liquid mixture is accelerated to supersonic speed and then decelerated to subsupersonic. The resulting shock wave disperses the gas in the liquid.

  US Pat. No. 5,302,325 to Chen discloses a method for dispersing gas in a liquid using a conical mixer. This mixer is placed in a cylindrical pipe and produces an annular flow. The gas is injected upstream of the mixer at supersonic speed. As the liquid / gas mixture passes through the annular gap, it is accelerated to supersonic speed and decelerated to subsonic speed, and the resulting shock wave disperses the gas. Annular flow makes a larger portion of the flow supersonic.

  Although these devices disperse the gas, they also have the problem of requiring additional energy to inject the gas.

  Venturi based injector mixers are also known. U.S. Pat. No. 4,123,800 to Mazzei discloses a venturi device having a contraction, a throat, and an expansion. A plurality of mouths are disposed at an angle inside the throat portion and communicate with the annular chamber around the throat portion.

  U.S. Pat. No. 5,863,128 to Mazzei discloses a venturi-type mixer injector with a constriction, a throat, and an extension. The inlet is shaped as a continuous groove in the throat. A plurality of torsional blades in the constriction cause a rotational movement in the outer portion of the flow, and a plurality of straight blades in the expansion remove some rotational movement to improve mixing.

  U.S. Pat. No. 5,893,641 to Garcia discloses a venturi driven injector having a converging portion, a throat portion, and an extension portion. A second (additive) fluid is injected through a plurality of radially arranged ports in a groove near the outlet of the extension. The second fluid is injected perpendicular to the main fluid flow.

  Gas-liquid separator

  The presence of entrained gas in the liquid often occurs and is often undesirable. These include boiler systems and hydraulic systems where entrained gas can cause noise or damage parts. Some systems intentionally entrain gas. These include the addition of nitrogen into the liquid to remove oxygen. In these systems, it is then necessary to remove both entrained gas and expelled gas and supply degassed liquid.

  Another use of gas-liquid separators is to remove those undissolved gases after oxygen or ozone has been entrained in water. Ozone is used to disinfect water. Water can dissolve a certain amount of ozone, but most ozonation processes will result in a certain amount of undissolved ozone gas. It is dangerous to release undissolved ozone directly into the atmosphere. There is a need for a method of removing and treating the undissolved ozone gas resulting from such a process.

  Redox potential (ORP) sensor

  Redox potential (ORP) sensors are known in the art. For example, U.S. Pat. No. 5,218,304 to Kinlen et al. And U.S. Patent Application No. 2003/0112012 to Mossley et al.

  US Pat. No. 5,218,304 to Kinlen et al. Describes a sensor that can be immersed in a fluid to measure the pH and ORP (redox potential) of the fluid. The described sensor uses a silver-silver chloride reference electrode and a noble metal ORP (redox potential) sensing electrode such as gold or preferably platinum. Disadvantages of using such a reference electrode include cost considerations in addition to the possibility of manufacturing consumer goods.

  US patent application 2003/0112012 by Mosley et al. Describes a galvanic probe having a sensor electrode and a reference electrode. The probe comprises a reference electrode of noble metal or antimony or bismuth (or an oxide or hydroxide thereof) and an oxidation-reduction potential (ORP) of zinc or magnesium (or an oxide or hydroxide thereof). The detection electrode is used. Disadvantages of using such detection electrodes include cost and the possibility of manufacturing consumer goods.

  Sanitization device and method

  The following US patents relate to disinfection and / or sanitization processes. US Pat. No. 5,851,375 to Bodger et al., US Pat. No. 6,379,628 to Jong et al., US Pat. No. 6,019,031 to Quinn et al., Bushnell U.S. Pat. No. 5,048,404 to Uin et al., U.S. Pat. No. 5,690,978 to Yuen et al., U.S. Pat. No. 6,093,432 to Mittal et al. U.S. Patent No. 6,086,932, given.

  Popular household water filtration devices are of the pitcher type that pours and filters (port-through). Typically, unfiltered water is placed in a water reservoir at the top of the device. Under the action of gravity, the water is filtered through a filtration medium (usually made of granular activated carbon) between the water receiver and the water collection reservoir. Thereafter, the filtered water is dispensed from the water collection reservoir for drinking. For the general public, gravity-controlled pitcher-type drainage systems are cost-effective. However, although purified water is obtained, gravity filtration cannot be introduced into purified water from sanitized gases such as ozone. Furthermore, the purified water so produced has little sanitizing effect on the surface with which the purified water comes into contact, except to mobilize or wash out bacteria, viruses, or other undesirable substances. .

  Pos-through devices cannot filter out and destroy smaller microorganisms and pathogens. In order to promote the flow of water, it is necessary that the filtration medium through which water passes is porous. Because of this need, such devices do not purify or sanitize water as efficiently as other water treatment devices. Part of this inefficiency is due to the lack of additional purification steps and relying solely on the filter itself. In addition, the filtration media or cartridge used in these pitcher-type through-through filtration systems extends down into the water collection reservoir and contacts the filtered water. This can be inconvenient if no other liquid purification or disinfection method is used. The porosity of the filtration media can even promote microbial infiltration, assembly and growth. Therefore, if the filtration medium extends into the water collection reservoir, the possibility of contamination of the filtered water increases.

  U.S. Pat. No. 5,222,078 to Polaski et al. Discloses a through-through gravity flow jug filter.

  U.S. Pat. No. 6,103,114 to Tanner et al. Describes an apparatus that attempts to prevent cross-contamination by the design of the spout, pour area, and seal between the internal reservoir and the drainage reservoir. Is quoted. However, the filter in this design still extends into the drainage reservoir and is a potential source of contamination. US Pat. No. 6,290,848 issued to Tanner et al. Discloses a porous granular filter for removing 99.5% of all 3-4 μ Cryptosporidium and other protozoan cysts. Yes. US Pat. No. 6,103,114, also granted to Tanner et al., Is a carafe-shaped lip that is higher than the edges to prevent untreated water from mixing with treated water when pouring. Describes the filter device.

  US Pat. No. 6,391,191 to Conrad discloses a pumped domestic water treatment device that uses ozone and a carbon block filter to disinfect water.

  US Pat. No. 6,238,552 to Shannon discloses a universal insert for a water purifier having upper and lower filters and a guide for sliding the insert into the pitcher.

  U.S. Pat. Nos. 4,969,996 and 4,306,971 to Hankamer disclose a column filtration device that extends into a water collection reservoir. This design can potentially provide a source of contamination.

  US Pat. No. 6,405,875 to Carter discloses a carafe-type filter device having an ion exchange resin and carbon granules that remove 99.95% of all 3-4 μ particles. Yes. However, this device is subject to contamination because it extends into the drainage reservoir.

Yet another optional component, for example, a centrifugal gas-liquid separator having an integrated gas release valve (referred to herein interchangeably as a “degasser”), an ozone destruction device, a redox potential Sensors or any other component that can sanitize liquids can be used.

  Double check valve

  The double check valve assembly according to the present invention allows, but is not limited to, control of fluid, particularly control of fluid entering and exiting the container. The container may be permanently attached or removable, and the inflow and outflow from the container may occur simultaneously or sequentially.

  Check valves are used in various applications where fluid flow needs to be restricted in one direction. Examples include filling and emptying tanks and controlling fluid flow in conduits such as pipes. However, if flow is required in two directions at the same time, for example, when inflow into and out of the tank is required simultaneously, two separate check valves are required, so the tank has two openings. Is required.

  According to one embodiment of the present invention, a double check valve is provided that allows two independent flows to occur simultaneously or independently through the same check valve assembly.

  A double check valve allows two separate independent flows to occur through a single check valve assembly. In addition, the device may include a cap that can divert one or both of the independent streams to provide good separation of the streams until sufficient mixing of the fluid from each stream is achieved. . The diverting means is disposed under the cap and, if present, can provide a direction of rotation for the flow of fluid passing therethrough. The check valve assembly also allows the container to be removed from the connection with the base and prevents fluid from leaking from either the base or the container when the container is not in place. The two valve stems housed within the check valve assembly can be operated independently or cooperatively.

  A double check valve comprises first and second valves that are independently operated, wherein the first valve is housed (particularly nested) within the second valve. It may be. In this way, two independent fluid flow paths are formed, one flowing around the first valve stem through the second valve stem and the second flow around the second valve stem. Flowing.

  According to one embodiment, the double check valve assembly includes an outer body having an inlet and an outlet, and the first and second valve stems are housed in the outer body. The outer body is the valve seat of the second valve stem. The first valve stem is smaller than the second valve stem, is contained within the second valve stem, and is actuated along a common axis. The second valve stem has a cylindrical conduit that passes through the second valve stem and accommodates the first valve stem, and also includes a valve seat for the first valve stem. As such, fluid can flow around the first valve stem and through the second valve stem. Separate springs surround the first and second valve stems. These springs act on the valves to engage their respective valve seats. The first and second valve stems can be operated independently or cooperatively.

  When these valves are open, two independent fluid flows occur, one flow is around the second valve stem and the outer body outlet, the other is the second Flow around the first valve stem passing through the valve stem.

  The double check valve assembly according to this embodiment is integral with the wall of a permanently mounted or movable fluid container that requires control of fluid input and / or output. Different types of containers for use with the present invention will be described elsewhere. This valve is preferably integral with the lower wall (floor) of the container.

  The first valve stem optionally has a cylindrical conduit formed partially through the first valve stem to allow fluid to pass when the first valve stem is not in contact with its valve seat. You may do it.

  The outer body may optionally include one or more protrusions disposed radially and surrounding the outlet and the first and second valve stems. These protrusions can take the form of mounting bosses or flow diverting means. If the protrusions are flow diverting means, they may be configured to give a rotational movement to the fluid exiting around the second valve stem. If the protrusion is an attachment boss, such attachment boss can be used to attach a removable cap to the outer body over the first and second valve seats. In such embodiments, the cap may comprise flow diverting means, a centrally located conduit and a valve seat.

  The cap can be attached to the mounting boss, in which case the diversion means provided on the cap forms a channel through which the fluid flows. The diverting means can impart rotational motion to the fluid. When the first and second valve stems are open, the second valve stem abuts the valve seat in the cap, and the first valve seat enters a conduit formed through the center of the cap. . Therefore, the two flow paths are effectively separated. One flow is the flow around the second valve stem passing through the diverting means under the cap and the other flow is the flow around the first valve stem passing through the central conduit of the cap.

As seen in this cross-sectional view, the fluid entering the first check valve flows through the center tube (404) for further processing, whereas the fluid passes through the second check valve. While waiting to return through, it flows into the central reservoir (604) through the return flow tube (406). When the double check valve assembly is removed from the mating member, fluid cannot flow upward through the second check valve. Only when the double check valve assembly is mated with the mating member can fluid flow out of the central reservoir. This advantageously allows the fluid to be retained if the container is not properly placed on the base.

  7 is a side view of the double check valve assembly and mating member of FIG. Cap (102), center tube (404), return flow tube (406), and central reservoir (604) are shown. In this embodiment, the return blow tube enters the central reservoir from an angled offset position that facilitates fluid mixing within the central reservoir. The top (702) of the mating member is shown, illustrating the area where the double check valve joins the mating member.

  Vortex-venturi device

  The vortex-venturi device is one aspect of the present invention relating to fluid injection and mixing. Specifically, this feature of the present invention allows for fluid mixing based on the Venturi principle, to accelerate the main fluid entering the device prior to mixing with the fluid to be added. The vortex member is introduced. When incorporated into the system of the present invention, the vortex-venturi device can entrap additive fluids such as ozone into a main fluid such as water to produce ozonated water for use in further sanitization processes. . The ozonated water so produced is itself a sanitized product. The device will first be described in terms of its function and then in terms of its role when incorporated into a sanitization system.

  The vortex-venturi device has a main fluid inlet, an additive fluid inlet, and an outlet for the resulting mixed fluid. Between the main fluid inlet and the mixed fluid outlet are a main fluid inlet channel, a shrinking portion that decreases in diameter, a throat, and an expanding portion that increases in diameter. The main fluid inlet is arranged perpendicular to the axis of flow through the outlet, and the main fluid inlet is arranged to have a tangential axis with respect to the inlet channel, thus forming a high-speed vortex. The tangential (or offset) main fluid inlet serves primarily to produce a vortex effect, so that the main fluid flows at high speed, thus improving the mixing between the main fluid and the additive fluid.

  According to this embodiment, the additive fluid inlet comprises a hollow tube or needle disposed centrally within the device. The additive fluid inlet extends into the throat portion, thus forming an annular channel around the inlet. One or more additive fluid outlet ports at the additive fluid inlet inject the additive fluid into the throat portion for mixing with the main fluid.

  The vortex-venturi device has the advantage that the gas (or additive fluid) is dispersed without having to use additional energy to inject the gas. The present invention has the advantage of using the Venturi effect to draw the additive fluid into the main fluid.

  A further advantage of the vortex-venturi device of the present invention is that the main fluid entering tangentially imparts rotational motion to the entire flow in the annular channel, thus forming an annular flow through the additive fluid injection process. It is. This causes more parts of the main fluid flow to reach high speed and brings more parts of the main fluid flow into direct contact with the additive fluid. The present invention also facilitates cleaning and allows changing the number, position and size of the exit port, or changing the needle diameter, and thus changing the cross-sectional area of the throat.

  One embodiment of the vortex-venturi device according to the present invention will be described below.

  According to one embodiment, the vortex-venturi has a cylindrical body with a main fluid inlet, an additive fluid inlet and an outlet. Between the main fluid inlet and outlet, a spiral main fluid inlet channel, a constricted portion with a decreasing diameter, which is either frusto-conical in shape or, preferably, a continuous curve, approximately There is a cylindrical throat portion and an expanded portion with increasing diameter that is frustoconical in shape.

  In this embodiment, the main fluid inlet is positioned perpendicular to the outlet flow axis and tangential to the spiral inlet channel, thus creating a high-speed vortex. Since the flow rate of the rotating fluid increases as the diameter decreases, the static pressure is decreased.

  The vortex-venturi device according to this embodiment has an additive fluid inlet with a central hollow needle extending into the throat portion. An annular channel is formed between the needle and the throat wall. In this embodiment, the hollow needle terminates at the throat portion in an outlet port located parallel to the outlet flow axis. Alternatively, the hollow needle may extend through the throat portion, end at the extended portion, and have a sharp point at the end. The needle may have a plurality of outlet ports formed perpendicular to the axis of the needle so that the additive fluid is injected into the throat portion.

  The additive fluid inlet needle may be formed as part of an independent body and may be removable from the vortex-venturi device or permanently attached or coupled to the rest of the vortex-venturi device. Also good. If the additive fluid inlet needle is removable, the additive fluid inlet needle may be attachable to the body by a snap-fit structure, clip, screw or other acceptable attachment means. The additive fluid inlet needle may be sealed by an O-ring or other method that would be clearly identifiable to those skilled in the art.

  The additive fluid inlet body may incorporate a check valve to prevent back flow of the main fluid from the additive fluid inlet when the main fluid flow is insufficient to create a vacuum.

  The removable additive fluid inlet body allows the additive fluid inlet body to be cleaned and / or replaced, so changing the needle diameter or the size, position and / or number of outlet ports to increase the mixing ratio and / or flow rate. Allows you to change.

  The vortex-venturi device according to one embodiment of the present invention may have a plurality of blades in the extended portion. These vanes may be positioned parallel to the flow axis at the outlet and arranged radially. They can interact with the rotating fluid flow to increase mixing efficiency.

  FIG. 8 is an isometric view of a vortex-venturi device (800) according to one embodiment of the present invention. A main fluid inlet (802) and a mixed fluid outlet (804) are shown. Optional coupling means (806) is illustrated as one possible way that the vortex-venturi device can be coupled with other components, for example, held in place within the sanitization system. ing.

  FIG. 9 shows an end view of the vortex-venturi device according to the embodiment of the present invention shown in FIG. An additive fluid inlet (902) is shown along with the location of the main fluid inlet (802), which is in the shape of a main fluid inlet channel that is visible from the exterior as the main fluid inlet channel shell (904). It is clearly shown that it has a tangential axis.

  FIG. 10 shows a cross section through the center of the embodiment of the vortex-venturi device (800) of FIG. 8 taken along line BB of FIG. In this view, the mixed fluid outlet (804), the coupling means (806), the additive fluid inlet (902), and the main fluid inlet channel shell (904) are shown. In addition, a main fluid inlet channel (1002) having a contraction portion (1004), a throat portion (1006), and an expansion portion (1008) is shown. A centrally located hollow needle (1010) continues from the additive fluid inlet (902) and ends at a sharp end (1012) at the throat portion (1006). Multiple, in this case four, additive fluid outlet ports (1014) allow the additive fluid to be injected into the main fluid accelerating in the throat section, two of these additive fluid outlet ports being It is shown in the figure. In this embodiment, a plurality of such ports are shown, but it should be understood that a minimum of one additive fluid outlet port is required for the present invention. In order to increase the mixing efficiency of the additive fluid and the main fluid, a plurality of vanes (1016) are present in the expansion portion (1008) and interact with the rotating fluid flow resulting from the vortex effect. It should be understood that a blade is not essential to the device and that at least one blade can be used if more than one blade is present. In this case, four blades are provided, three of which are shown in the cross-sectional view. An extension (1008) is placed near the mixed fluid outlet to create a low pressure zone that has a vacuum (depressurized) effect that passes fluid through the vortex-venturi device to the mixed fluid outlet (804). Yes.

  When incorporated in an embodiment of the sanitization system according to the present invention, the vortex-venturi device is arranged downstream of the ozone generator. Therefore, ozonized air is supplied to the additive fluid intake from the upstream ozone generator. The ozonated air is drawn in by the vacuum (reduced pressure) created in the vortex-venturi device. In addition, the ozonized air may be supplied to the additive fluid inlet by a pump. Water pumped from a container accessed through a double check valve is fed to the main fluid inlet, forming a vortex in the main fluid inlet channel, and the venturi effect draws water through the contraction part, By increasing the pressure and passing through a throat section with an additive fluid outlet port, high pressure and acceleration of water allows efficient mixing of ozone and water, and further mixing interacts with ozone and water. Then, it is performed in the extended part that is further mixed. At the mixed fluid outlet, much (water and) ozone is dissolved in the water and only a portion of the added ozone remains as a separate gas. For the remaining ozone gas in the system, a gas-liquid separation device with an integral gas release valve may be incorporated to continue downstream of the mixed fluid outlet.

  Ozone generator

  The ozone generator incorporated into the system according to the present invention is a device that generates cost-effective corona discharge. Ozone can be generated by a discharge (eg, “spark”) that splits oxygen molecules into two oxygen atoms. This discharge is also referred to as “corona discharge”. These unstable oxygen atoms combine with other oxygen molecules, and this bond generates ozone.

  The ozone generator according to an embodiment of the present invention is preferably a corona discharge type ozone generator. The corona discharge ozone generator includes two cylindrical insulating end caps, a high voltage electrode, a ground electrode, and a dielectric material. The construction of an ozone generator having a large inner diameter with respect to the length allows heat dissipation over a long period of time, thus producing a stable amount of ozone.

  The end cap is designed to maintain a constant air gap between the dielectric and the high voltage electrode. Air enters the end cap tangentially and creates a vortex effect through the ozone generator, thus lengthening the time that exists between the dielectric and the high voltage electrode and increasing ozone production efficiency. The end cap has a large open end that is closely aligned with the inner diameter of the high voltage electrode to allow heat dissipation during the corona discharge process. Alternatively, a fan may be attached to the end cap to provide convection cooling to the generator. However, due to the large inner diameter design of the ozone generator that allows heat dissipation, a fan is not necessary.

  The end cap is bonded to the ground electrode surface and the dielectric using an adhesive.

  The preferred dielectric material is silicon borate glass, although other materials such as ceramics or thermoplastics can be used.

  A high-pressure electrode composed of a large inner diameter, welded or seamless stainless steel tube allows for heat dissipation during the corona discharge process.

  According to this embodiment, the ground electrode surface comprises a thin stainless steel foil laminated on one side with a high temperature adhesive. This foil is then adhered to a dielectric material (eg, glass), thus forming a ground electrode surface.

  The relative lengths between the ground electrode surface, the dielectric material and the high voltage electrode are different to eliminate arcing between these components through the end cap.

  Another configuration of the ozone generator includes an air pump disposed in fluid communication with an input to the corona discharge ozone generator, for example in the base (if the system incorporates the base). The air pump is used to send air through the corona discharge ozone generator, thereby ensuring a sufficient supply of incoming air. The charged air emerging from the corona discharge ozone generator may then be blown into a fluid container using a sparger or a porous ceramic structure. In this case, the presence of the vortex-venturi is optional since ozone will be taken directly into the container. Where multiple containers are provided, each container contains a sparger and is in fluid communication with the base. Of course, a combination of an air pump and a system incorporating a vortex-venturi is encompassed by the system according to the invention.

  FIG. 11 is an isometric view of an ozone generator (1100) according to one embodiment of the present invention. End caps (1102, 1104), ozone outlet (1106), and air inlet (1108) are shown. These inlets and outlets are both arranged perpendicular to the gas flow axis passing through the ozone generator, and both are arranged tangential to the circumference of the ozone generator. In this way, the air entering the generator travels along the spiral path through the ozone generator and past the electrodes. Thus, the spiral path allows the same volume of air to have a longer exposure time within the generator, thus increasing the amount of ozone per unit volume of air entering the ozone generator.

  12 is a plan view of the ozone generator shown in FIG. End caps (1102, 1104), ozone outlet (1106), air inlet (1108) are shown.

  13 is a cross-sectional view through the center of the embodiment shown in FIG. 11 taken along line DD in FIG. A high voltage electrode (1302) is shown.

  FIG. 14 is a detailed sectional view of the dielectric, adhesive, and ground electrode structure of the ozone generator obtained from the detailed section E of FIG. The stainless steel foil, which is the ground electrode (1402) in this embodiment, is shown as the outermost layer and the high temperature adhesive layer (1404) is placed under the ground electrode, in this case a dielectric that is a glass tube (1406) is shown directly below the adhesive layer. In one example, a typical voltage for the high voltage (inner) electrode is about 4000V, while the ground (outer) electrode is 0V.

  When incorporated in a system according to the present invention, the outlet of the ozone generator is upstream of the vortex-venturi additive fluid inlet and is in communication with the additive fluid inlet, thereby providing a centrally located hollow needle outlet. Supply ozone as additive fluid through the port.

  It will be appreciated that the remaining components of the system described herein below are optional. None of the following components are required for the system of the present invention to function or operate. However, according to one embodiment of the present invention, each of the components described below is present.

  Centrifugal gas-liquid separator with integrated gas release valve

  Centrifugal gas-liquid separators can be used with embodiments of the sanitization system according to the present invention. This separation device is interchangeably referred to herein as a “deaeration device”. This separation device is provided with an integrated gas release valve, which makes it possible to remove the entrained gas from the liquid flow. More specifically, when ozone gas is entrained in the flow of ozonized water, gaseous ozone can be removed using this separation device.

  The gas-liquid separator is in fluid communication with the mixed fluid outlet of the vortex-venturi device so that entrained ozone gas can be removed from the ozonated water. The gas-liquid separator promotes efficient removal and release of potentially harmful ozone gas while leaving dissolved ozone in the liquid phase. Therefore, generation of degassed ozonized water is performed by this system.

  According to one embodiment of the present invention, a liquid-gas mixture is injected tangentially into the helical channel via the liquid-gas mixture inlet, which creates a high-speed vortex. The swirling liquid-gas mixture rises up the tube, and under centrifugal force, the gas is pushed to the center of the vortex and the liquid is pushed to the periphery. As the liquid-gas mixture rises through the tube, slots around the tube draw a portion of the liquid and the drawn liquid is discharged through the liquid outlet. The remaining liquid-gas mixture rises and enters the valve chamber. The liquid level in the valve chamber interacts with a float that opens and closes a port that releases gas as needed.

  In one embodiment of the present invention, the gas-liquid separator takes in centrifugal force and includes a gas release valve. The liquid-gas mixture passes under pressure through the nozzle and tangentially enters the helical channel in the base of the separator. The liquid-gas mixture rises up the tube in a rapidly rotating vortex. As the vortex rotates, a centrifugal force is created, pushing lighter gas to the center and pushing heavier liquid outwards against the wall of the tube. Slots placed around the inside of the tube draw a portion of the liquid from the outlet tube after drawing a portion of the liquid into the annular chamber around the tube. The remaining liquid-gas mixture rises and enters the valve chamber. The float interacts with the liquid level to open and close the port. Since the gas is released from the port according to the liquid level, the pressure in the system is maintained.

  According to this embodiment, the float can take the shape of a torus that allows gas to pass through the center while minimizing vortex motion. In addition, not only a spherical shape but also a central closed torus shape can be adopted. The float may interact with the port through a lever arm and a seal built into the lever arm. The lever arm increases the float force (both buoyancy and gravity), effectively sealing the port when the liquid level is high, and pulling the seal away from the port when the liquid level drops. In this case, the lever arm effectively pulls the seal away from the port against the internal pressure of the system, allowing gas to escape. In addition, an electronic float switch may replace the float and the lever arm, and the valve can be opened and closed to exclude air.

  The tube of the gas-liquid separator can be either cylindrical or frustoconical with a diameter increasing from bottom to top.

  The cap that forms the bottom of the helical channel at the base of the gas-liquid separator is removable so that the separator can be drained and / or cleaned. The valve chamber cap may include the center of rotation of the gas outlet port and arm lever. This cap is either permanently fixed to the separation device or is removable for inspection and cleaning of the valve assembly and / or valve chamber.

  The cap may incorporate a mount for the baffle. The baffle may have a hole through its center and is aligned with the center axis of the float. This hole allows gas to escape through the baffle and through the port. This hole also allows the arm to connect with the float. When installed, the baffle reduces the chance of fluid exiting the gas port.

  FIG. 15 is an isometric view of a centrifugal gas-liquid separator (1500) according to an embodiment of the present invention. A liquid-gas mixture inlet (1502) is shown having a flow axis tangential to the circular channel of the separator. This configuration can form a high speed vortex. A central tube (1504) is placed over the inlet through which the rotating liquid-gas mixture rises. A liquid outlet (1506) located above the central tube is shown. A gas outlet (1508) is disposed at the top of the gas-liquid separator. An optional connector (1510) is shown for holding the gas-liquid separator in place within the sanitization system of the present invention.

  FIG. 16 is a plan view of the gas-liquid separation device of FIG. A liquid outlet (1506), a gas outlet (1508), and a connector (1510) are shown.

  17 is a cross-sectional view taken along line CC of FIG. 16 and passing through the center of the gas-liquid separator of FIG. In addition to the liquid-gas mixture inlet (1502), central tube (1504), gas outlet (1508), lever arm (1702), lever arm holding member (1704), lever arm rotation center (1705), valve chamber (1706) ), Lever arm seal (1708), valve chamber cap (1710), float (1712), vortex tube (1714) and separator base (1716). As can be seen in this cross-sectional view, a narrow gap (1718) at the top of the central tube allows liquid to be removed between the vortex tube (1714) and the valve chamber (1706).

  A gas-liquid separation device is an optional component of the system, but certain features have been shown to be beneficial to the embodiments described herein when present. When the gas-liquid separator is used in a small scale system of the present invention having a total height of about 3 to 6 inches (7.62 to 15.24 cm) {approximately 4 inches (10.16 cm)}. The following dimensions can be used. The narrow gap (1718) may be 0.01 to 0.1 inches (0.0254 to 0.254 cm), preferably 0.02 to 0.06 inches (0.0508 to 0.1524 cm). Conveniently, there are few steps where the narrow gap meets the central tube (1504). Alternatively, some kind of tube extension extending upwards is advantageous. The height of the central tube (1504) may be about 1 inch (2.54 cm) in an embodiment where the overall height is 4 inches (10.16 cm). However, separators with overall heights ranging from 3 to 6 inches (7.62 to 15.24 cm) (respectively) have about 0.5 inches (1.27 cm) to about 3 inches (7.62 cm). ) Any height would be convenient. Dimensionally, the height of the central tube can be about one quarter of the total height of the separator. The angle of inclination of the central tube can range from 0 ° (no angle) to about 15 °.

  The inlet port and tube of the separation device can act as a turbomixer that helps dissolve ozone in the water. This effect is achieved and good mixing is obtained with a configuration in which the inlet tube is arranged in a tangential direction with respect to the longitudinal axis of the separating device and the intake into the inlet is fast.

  As an alternative to a gas-liquid separator, a mixing tube (or “bubble breaker”) that can break up bubbles in the fluid stream can be used. A set of mixing tubes and bubble breakers serves to effectively dissolve ozone in water and can be used instead of ozone degassing. The bubble breaker mixing tube may be used in certain jurisdictions that do not remove excess ozone but do not require ozone removal and / or destruction.

  Capacitive high voltage detection system to detect high voltage supply failure

  The corona generator relies on high voltage and high frequency power supply to generate the ozone required for the embodiment of the invention that uses the ozone generator. Confirming that the generator is receiving this supply helps to verify that the device is functioning properly. A cost-effective and reliable detection system (referred to herein interchangeably as a “high voltage detector”) is described. This detection system can detect power supply to the ozone generator.

  High voltage detectors take advantage of the fact that a high frequency, high voltage power supply to an ozone generator can send a useful large signal to a detector circuit through a small capacitor. This capacitance is generated between the high voltage component and the input to the detection circuit.

  Capacitance is created simply by connecting one end of the wire to the input end of the detection circuit and wrapping the other end around an insulated high voltage supply wire for the ozone generator.

  Other means for holding the high voltage detector wire in the vicinity of the high voltage supply wire or other high voltage components may be used as well. Other possible arrangements of conductive and insulating components that create and utilize capacitance between the high voltage component and the input to the detection circuit will be apparent to those skilled in the art and are within the scope of the present invention. Is included.

  FIG. 18 is a schematic diagram of a capacitive detection device (or high voltage detection device) circuit that can be used with an embodiment of the present invention. The capacitance resulting from the close proximity of the conductors sends a signal. A high voltage detection device is shown, and the current path in this device (returning to the common path to complete the circuit) may be wired or provided by stray capacitance. The high voltage detection device cooperates with the microprocessor to detect a high voltage supply failure.

  As shown in FIG. 18, the ozone generator is equipped with a high-frequency AC power source. This embodiment of the high voltage detection system (1800) operates as follows. The high voltage that feeds the ozone generator passes through a supply wire (1802) to the ozone generator. This wire is connected to a high frequency AC power source (1804) for the ozone generator (1806). A wire (1808) in close proximity to the high voltage that feeds the ozone generator is in close proximity to the wire (1802) for a portion of its overall length. This gives rise to a small capacitance marked as capacitor (1803).

  A high frequency, high voltage signal through the wire (1802) causes a small amount of current to flow through the capacitor (1803). This current causes a voltage to appear at the input of the high voltage detector (1810) through the wire (1808).

  The current path (1812) for the current in the wire (1808) is completed in the flow path (1812) shown as a dotted line connecting to the circuit common path (1814). This current path may be provided by stray capacitance or may be provided by physical components such as wires, resistors, capacitors or other forms of finite impedance.

  The high voltage detector circuit (1810) can be implemented in a variety of ways, as will be appreciated by those skilled in the art of electrical design. The circuit (1816) showing an exemplary embodiment of the high voltage detector is a monostable flip-flop that is “ON” when a voltage appears on the wire (1808). The monostable flip-flop (1818) returns to the “OFF” state when the time expires, and in this state, the monostable flip-flop is turned on again by a signal appearing on the wire (1808). The microprocessor (1820) monitors the activity of this flip-flop and confirms that the flip-flop is spending the appropriate portion of time in the “ON” state. When the processor detects that the monostable flip-flop is not "ON" for an acceptable percentage of time, the processor registers a high voltage supply failure.

  In this embodiment, the system further includes a high-voltage, high-frequency power supply detection device to confirm proper power supply to the corona discharge generator. The sensing device includes a lead (or “first wire”) in contact with the high voltage / high frequency lead to the corona generator and a lead in close proximity to the high voltage / high frequency lead to the corona generator. A line (or “second wire”) and a detection circuit. The detection circuit can be either externally powered or powered through the capacitance of the detection wire. In this embodiment, the capacitance occurs because the first wire and the second wire are very close. The detection circuit is electrically connected to the second wire for the purpose of detecting electric capacity. This circuit has a microprocessor and a monostable flip-flop to confirm power supply to the corona discharge generator.

  Redox potential (ORP) sensor

  The processing time of the sanitization system can be controlled manually or automatically. If automatic control is desired, there are options to either control by time or by the ozone concentration level of the resulting ozonated water. In a preferred embodiment of the system, process control is determined by ozone concentration. Therefore, a sensor for detecting ozonization in water may be incorporated. This sensor may be located anywhere in the system of the present invention as long as it is in contact with the ozonated fluid.

  The sensor described herein is one of many any sensors that can be incorporated into the system of the present invention. In this embodiment, the reference electrode and the ORP sensing electrode are in fluid contact with the sanitization system. The first electrode which is a reference electrode is made of a silver material. This electrode may be solid silver or silver plated on a substrate. The ORP sensing electrode is a noble metal, either platinum or gold, and may be solid platinum or gold, or the metal may be plated on the substrate.

  In one preferred embodiment, the reference electrode and the ORP sensing electrode are plated on a stainless steel screw. These screws are then screwed into the inlet tube so that the lower portion of each screw is in fluid contact with the water flow through the inlet tube. Lead wires are attached to these screws using terminal lugs. When water rich in ozone passes, a redox potential is generated. This potential is determined by the standard electronic components of the system and thus controls the processing time.

  Screws can be easily mass produced and silver and platinum plating methods are well known to those skilled in the art and widely used by those skilled in the art. The assembly of the sensor is simple and economical.

  FIG. 19 illustrates the position and preferred embodiment of the ORP sensor in the mating member shown attached to the mating member (402) of the sanitization system, eg, the double check valve (100) of FIG. ing. A center tube (404), return blow tube (406), and central reservoir (604) are shown. The placement of the electrodes (1902 and 1904) proximate to the center tube through which fluid enters the system is shown.

  Gravity supply filter and any other water purification technology

  The present invention may include a gravity supply filter. In such embodiments, the gravity feed filter may be an inter-fabric extruded carbon filter, a non-extruded carbon filter, or a fabric filter that does not contain any activated carbon. The gravity supply filter may be disposed upstream of the liquid container, may be integrated with the liquid container in the form of an upper reservoir, and the volume of the container may be divided into an upper reservoir and a filtrate reservoir. The gravity supply filter preferably does not extend into the water in the filtered water reservoir. However, the system may include a gravity supply filter that extends down into the filtrate reservoir as an alternative to a filter that does not extend down into the filtrate reservoir. Such a filter may be in the form of a removable, disposable and / or refillable cartridge.

  Additional purification techniques can optionally be used in addition to the system. For example, electrodes; ultra, micro and nanofiltration; ultraviolet (UV) light sources; or additional aeration / oxygenation. Additional purification techniques, if present, are suitably arranged to act on the water as it flows through the system. As an additional purification technique, a pulsed electric field sanitization technique can be used that incorporates an electrode to sanitize or purify water that passes through the electrode. For example, such technology is described in the applicant's co-pending international application No. PCT / CA2004 / 000043 filed Jan. 9, 2004, the contents of this international application being referred to. Is incorporated herein by reference.

  Embodiments of the present invention involving gravity filtration include a container having an upper reservoir for receiving unfiltered water. The upper reservoir has a lower opening, a filtration medium in the lower opening of the upper reservoir for filtering unfiltered water passing therethrough, and a lower filtered water reservoir for receiving water that has passed through the filtration medium. . The filtered water reservoir has a lower opening that connects to the double check valve.

  In one embodiment of the invention using gravity filtration, the container may comprise a pitcher having an inter-fabric flat extruded carbon sheet as the filtration medium. The extruded carbon sheet is located on the floor of the upper reservoir. A lid may be provided to cover the upper reservoir. The water contained in the upper reservoir slowly penetrates the extruded carbon sheet and flows into the lower reservoir of the pitcher. The pitcher may be located at a specific location on the base. As yet another alternative, an air pump connected to the lower reservoir of the pitcher supplies air to the sparger medium in the lower (filtered water) reservoir, thereby releasing bubbles into the water contained in the pitcher This makes it possible to further purify water. In this embodiment, a plastic reflector may be placed over the sparger medium to assist in the circulation of the foam. In fact, this allows both water purification by filtration through an extruded carbon filter and water purification by aeration / oxygenation using a pump in communication with the pitcher. A double check valve may be incorporated in this embodiment to ensure that water flows into and out of a suitable pitcher. In order to be able to detect the pitcher placed on the base (so that it can be detected that the pitcher is placed on the base), an electronic control unit may be used in the base. The extruded carbon filter preferably does not extend below the upper reservoir floor, but it should be understood that an extruded carbon filter can be used that extends below the upper reservoir floor and extends into the water contained in the lower reservoir. It is.

  Multipurpose sanitization system

  The system according to the present invention is a multipurpose sanitization system having a fluid container and components capable of generating ozone, fluid ozonation, and circulating fluid back to the fluid container. Optionally, other liquid purification techniques may be used in combination with the liquid purification techniques disclosed herein. In addition, any means for removing excess (undissolved) ozone, means for detecting ozone levels, and means for destroying excess ozone can be used. The fluid container may optionally be removable. These components may be housed in a base on which the container is placed.

  According to one embodiment of the invention, the components of the system are housed in a base on which the container can be placed or a base to which the container is connected (if the container is not removable). Also good. These components include a pump, an ozone generator, and a vortex-venturi for taking ozone into the main fluid. A double check valve for allowing liquid to flow into and out of the container at the same time is connected to the container and, for embodiments in which the container is removable, has a mating member integral with the base. May be. A centrifugal gas-liquid separator is optionally included in the base. As yet another option, an ozone destruction device, an oxidation-reduction potential (ORP) sensor, and control electronics may be incorporated.

  The container (or containers) can either be removable or secured within the system. If the container is integral to the system (it cannot be easily removed from the system), the container may be in the form of a storage tank. This type of container can be applied to large designs that do not necessarily require the user to be portable. However, for small or residential applications, it is possible to have a fixed position non-removable container where an aliquot of ozonated water can be pumped, for example, through a faucet or via a conduit to a selected device. desirable.

  According to one embodiment, the system comprises a plurality of removable containers. Of course, the system of the present invention only requires one container, which need not be removable. Embodiments in which more than one container is provided and these containers are removable are described herein below. In this embodiment, the control electronics incorporates an automatic detection circuit to detect which type of fluid container is connected to the base and launch an appropriate program. For example, if a fluid container necessary for drinking water is detected, a lower level of ozonation is desirable. Also, higher levels of ozonation are desirable when a fluid container that can be used to clean the surface is detected.

  As an alternative to automatic sensing circuitry, the user may select an appropriate cycle. The treatment time can be controlled manually or can be set to automatic control based on the time and / or ozone concentration of the resulting water.

  Removable containers incorporate a double check valve at their bottom that connects with the base unit. This configuration allows water to flow out of and into the container at the same time while using a single connection point.

  In one embodiment of the invention, the automatic detection circuit is activated when the container is placed on the base. An appropriate program (which is optionally a program specific to the container) is activated and the ready light is turned on. The user then starts the process by pressing a button. The pump draws water from the container and sends it through the venturi. The venturi has a gas inlet that draws in ozone-enriched air from an ozone generator. The ozone generator may be of a corona discharge type and converts part of oxygen in the air into ozone. Alternatively, the ozone generator may be of any other acceptable type. Ozone is mixed with water in a vortex-venturi to produce ozonated water. Next, the ozonized water enters the centrifugal gas-liquid separator, and the centrifugal gas-liquid separator does not dissolve air or undissolved ozone, etc. while leaving the dissolved gas present in the ozonized water. Remove gas. The removed gas can be sent to an ozone destruction device, which converts ozone into oxygen and releases oxygen safely into the atmosphere.

  In addition, the gas-liquid separator may be similarly effective when the excluded gas may be sent back to the venturi inlet and dissolved again in water, or the excluded gas may be sent to the ozone generator inlet. The ozonized water leaves the gas-liquid separator and is sent back to the fluid container. This cycle continues until a predetermined time and / or ozone concentration is reached. An ORP sensor that continuously monitors the level of ozone in the water and controls the process cycle of the unit is located at the inlet of the system.

  As a further alternative to re-dissolving gases excluded from gas-liquid separators, in some jurisdictions it is also optional to release such excluded gases (including ozone) to the atmosphere. If the regulations allow in the jurisdiction, there is no need to recycle exhausted gases containing ozone or destroy ozone. In North America, there are regulations that define acceptable levels of excluded ozone.

  When the process is complete, the user is contacted by a light and / or audible alarm indicating that the container can be removed.

  Each container may incorporate a double check valve at the bottom, which is connected to a system base receptacle and allows the container to be removed without leakage. This check valve allows water to flow out of the container and back into the container without the need for additional connections. Water flows out of the container by a pump or other means, passes through the venturi, passes through the deaerator, and flows back into the container. The process continues until a preset time and / or ozone concentration is reached. Ozone is generated in an ozone generator and mixed with water in a venturi. A gas-liquid separator removes undissolved ozone along with the accompanying air. The ozone removed by the gas-liquid separator is dissociated by the ozone destruction device and released safely into the atmosphere.

  The container can optionally take the form of a pitcher for sanitizing portable water. The container can also take the form of a bowl and strainer for sanitizing fruits and vegetables. In addition, the container may take the form of a spray bottle containing ozonized water applied to the surface, or the form of a reservoir and pad for cleaning the surface. The container may take the form of internal and external containers for sanitizing small objects such as dentures, infant pacifiers and the like. Further, the container may be a decanter for storing ozonized water when a larger amount of ozonized water is required. Examples include rinsing utensils (kitchen utensils) and hands when applied to food such as meat.

  The sanitization system has a variety of uses, both for personal use at home and for industrial and / or medical use. Examples of these applications are the preparation of purified drinking water or the production of ozonated drinking water for the sanitization of objects or surfaces. Ozonated water generated using this sanitization system should be used for the treatment of acne, foot fungi, and other medical conditions (sanitary origin related to bacteria), cut sanitization, topical skin treatment, and medical device cleaning. Can do. The industrial use of the food manufacturing industry can use the ozonated water produced by the present invention. For example, there are commercial uses in surface processing in food processing plants (such as meat processing plants) such as restaurants and factories, food packaging plants, and supermarkets where products are required to be kept fresh. The shelf life of fresh products can be extended by regular spraying with ozonated water produced by the present invention. Employees can benefit from the availability of ozonated water for hand washing at work or public places. Plants and flowers can be sprayed or watered with ozonated water produced by the present invention.

  For home use, vegetables and fruits can be rinsed in a strainer-shaped container attached to the base. For the maintenance of the oral cavity, the ozonized water thus produced can be used to clean teeth, toothbrushes or as a mouth rinse. Ozonated water can also be taken into the home for wound care instead of stronger solvents such as rubbing alcohol or hydrogen peroxide. The ozonated water thus produced can be used as a deodorant to spray the surface or inner surface of shoes or the like.

  In addition, for home use, the system can be installed as a counter-mounted type or as a unit built upstream to supply water to household equipment. By using ozonated water for washing clothes or dishes, the amount of detergent required can be reduced or the detergent can be omitted.

  Many other industrial and residential applications can be devised by those skilled in the art, and these are within the scope of the present invention.

  FIG. 20 is a schematic diagram of an embodiment of a multipurpose sanitization system according to the present invention. FIG. 20 shows the base (1) and the removable container (2). The treatment vessel incorporates a double check valve (3) that allows water to flow into and out of the vessel via a single connection. When the container is placed in the base, the double check valve connects with the socket (21). An automatic detection circuit incorporated in the electronic device (9) activates an appropriate program to start the ozonation process.

  When the system is in operation, water is pumped from the container, enters the socket through a double check valve, and enters the pump through conduit (10). The water then flows through the conduit (11) and enters the vortex-venturi (5). As the water flows through the vortex-venturi, the water draws air through the input end (13) to the ozone generator and creates a vacuum (depressurization) that pulls the vortex-venturi through the tube (12). The ozone generator is of a corona discharge type and converts part of oxygen in the air into ozone.

  Water with bubbles containing ozone and air leaves the venturi through conduit (14) and enters the centrifugal gas-liquid separator (7). Centrifugal force generated in the gas-liquid separator drives all air and undissolved ozone out of the water. The extracted gas is sent to the ozone destruction device (8) through the tube (16). The destruction device that dissociates ozone into oxygen and safely releases oxygen to the atmosphere (17) preferably includes a CARULITE ™ catalyst (CARUITE is a Carus Corp, Illinois, Peru). .) Is a registered trademark).

  The water now containing dissolved ozone is sent back to the container (2) via the conduit (15) and socket (21), through the double check valve. The process continues until the program ends.
