摘要:
Water sanitizing apparatus is provided for pools, spas hot tubs and other similar bathing facilities that integrates an ozone generator and a chlorine generator in one unit, in addition to exposing a flow of water to be purified to ultraviolet radiation from the ozone generator for advanced oxidation reactions. In one embodiment, a mixing venturi allows for mixing various substances together prior to insertion into the motive flow. In another embodiment the venturi is constructed as inserts that allow tuning of the venturi for individual systems. In other embodiments, salt is added to a portion of the water flow as a concentrated brine from which chlorine is generated, or the salt may be simply be added to the water of the facility at a much lower concentration and chlorine generated from the flow of water through the apparatus.
摘要:
A process for sanitizing and cleaning wherein water containing ozone and other substances is sprayed through a spray head. The spray head contains a mixing chamber wherein ozone and other chemicals are mixed prior to being sprayed. The spray head also imparts an electrostatic charge onto the water or cleaning solution prior to be emitted from the spray head. Ozone is drawn into the spray head from an ozone generator through a tube positioned near the mixing chamber. The ozone generator may further comprise orienting at least one port on both a first and a second Venturi in the interior of the ozone generator to enhance the process of ozone production. A halogen generator may be incorporated into the process to add a sanitizing halogen to the water or cleaning solution.

A method for connecting a chlorine generator to a pipe carrying a flow of water is disclosed. A short section of rigid pipe conveying water to the chlorine generator is configured at an end inserted into the water flow so that the flow forces water into the rigid pipe and into the chlorine generator, and a second short section of rigid pipe that returns chlorinated water from the chlorine generator to the flow of water is configured at an end inserted into the water flow so that the flow draws the chlorinated water into the flow. A single clamp around the pipe carrying the flow may be used to mount both sections of short rigid tubing to and from the chlorine generator.

An adjustable Venturi is disclosed, and having a plurality of inlet ports providing substances to be mixed with a flow of fluid through the Venturi. In one embodiment, the Venturi is constructed having an inlet portion, an outlet portion, with an annular mixing chamber coupled to inlet ports so that substances provided through inlet ports are mixed in the mixing chamber, and such mixture introduced into the flow. A gasket sealably disposed between inlet portion and outlet portion is selectable in thickness, for adjusting width of a Venturi interface between the inlet portion and outlet portion. In another embodiment, the inlet portion and outlet portion are fitted in an elongated opening, and are replaceable to change operational characteristics of the Venturi. A replaceable disk having a central opening and substance-providing passageways is disposed between the inlet portion and outlet portion, and may be changed to change characteristics of the Venturi.

A combined ozone and ozonites generator and ozone eliminator is disclosed. The device uses different modes of operation to control generation or elimination of ozone, with some modes being used for generating ozonites, some of which are generally less reactive and provide more far reaching beneficial effects than ozone alone. The device uses 185 nm radiation to disassociate atomic oxygen leading to creation of ozone, and uses 254 nm radiation to disassociate ozone, reducing its concentration, with both processes leading to creation of ozonites. These effects are achieved by operating either lamp separately or by operating both lamps simultaneously while drawing air through a chamber containing the lamps.
摘要:
A water purifying apparatus is constructed having a plurality of vertical, water-carrying tubes circumferentially arranged so as to form a hollow central region enclosed by the tubes. A top cap and bottom cap are configured so as to channel water through the tubes in serial relation and alternately in upward and downward directions. The hollow central region forms a last water-carrying chamber, and houses a bubble separator and ozone generator. A venturi mixes ozone at an inlet to the first water-carrying tube. The ozone generator is constructed having an ultraviolet-transmissive tube sealed from the water in the hollow central region, and contains an ultraviolet lamp that in addition to generating ozone, provides ultraviolet light to kill pathogens that survive the ozone treatment and also disassociates ozone. A closed loop system may be implemented by providing gas from the bubble separator back to the venturi.
摘要:
A system and method for purifying air is provided. An air purifier may include a housing, a means to move an airstream into the housing, and a pair of ultraviolet radiation generating means and associated control means to produce ozone to destruct airborne contaminants. The housing may be an elongated hollow tube, and the ultraviolet radiation generating means may be lamps of generally cylindrical shape axially aligned in the hollow tube. The control means may be lamp drivers and timers. The air purifier may further include a reactive filter across an exit means to reduce residual amounts of ozone in the stream of air passing through the exit means.
摘要:
A system is proposed for cleaning and sterilization wherein a carrier fluid is provided through a spray head having a mixing chamber, the flow of carrier fluid converted to a spray by the spray head. In the mixing chamber, ozone and ozone reaction products are mixed with the flow of carrier fluid to obtain a higher mixture of ozone and ozone reaction products in the carrier fluid immediately before the carrier fluid and ozone and ozone reaction products are dispensed as a spray.

Methods and apparatus for efficient implementation and control of water treatment bypass loops combining ozone and chlorine injection are disclosed. Combined use of ozone and chlorine exploits high oxidation potential of ozone while retaining longer lived residual effectiveness of chlorine for high efficacy against contaminants, particularly biological and organic. Embodiments including automated monitoring and control of chlorine concentrations in presence of high oxidation potentials from ozone are disclosed, as is an inexpensive circuit for using a signal from a redox sensor for controlling output from an electrolysis cell. Also disclosed is a multipurpose enclosure that may be used, with different inserts, to implement an electrolysis cell, an ultraviolet ozone generator, an advanced oxidation unit, or an erosion feeder for adding dissolved salt to water for use in an electrolysis cell. The multipurpose enclosure helps reduce cost associated with maintaining inventories of different components used in water purification systems.
