In an ozone generation apparatus, a discharge cell includes a first electrode part, a second electrode part, and a dielectric partition plate. The first electrode part and the second electrode part face each other, and the dielectric partition plate is provided between the first and second electrode parts.

A long-life discharge tube for ozone generator is provided, including an air inlet tube, a connecting column, an ozone outlet tube, inner and outer quartz tubes, an outer copper foil, first and second high-voltage connecting components. The outer side of the connecting column fits closely to the inner quartz tube. The outer quartz tube is sleeved on the inner cylindrical component. An air gap is provided between the inner and outer quartz tubes. The outer side of the outer quartz tube fits closely to the copper foil whose length is less than that of the inner and outer quartz tubes. Two connecting components for generating high voltage for arcing are respectively connected to the inner cylindrical component and the outermost copper foil. This structure can prevent the oxidation and corrosion due to the electric spark on the connecting column, greatly improving the overall service life of the discharge tube.

An ozone injector device comprising a housing having a water passageway through the housing, a corona tube disposed within the housing and configured to generate ozone, an ozone inlet fitting removably coupled to the water passageway, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube, and a spring-loaded clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet. The clearing piston is biased upwards, towards to the ozone inlet, and configured to prevent flow of ozone into the water passageway.

An air scrubber system including a system for creating an oxidation reduction potential (ORP) in water is disclosed. The system includes a pipe assembly for in-line mixing. The pipe assembly includes a first flow path for water to flow through. The first flow path includes one or more ozone intake ports that are fluidically coupled to one or more ozone output ports of an ozone supply unit. The pipe assembly further includes a second flow path fluidically coupled in parallel with the first flow path. The second flow path includes a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path through the one or more ozone intake ports and mixed into the water flowing through the first flow path.

An ozone injector device comprising a housing, a corona tube disposed within the housing and configured to generate ozone, a check-valve removably coupled to the water passageway, a second end of the check-valve having a cavity with a movable float contained therein, an ozone inlet fitting removably coupled to the check-valve, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube such that ozone entering the water passageway through the ozone inlet fitting must pass through the check valve, and a spring-loaded clearing piston positioned to move into and out of the water passageway, the clearing piston being biased upwards, and configured to prevent flow of ozone into the water passageway.

A degassing chamber for an ozone solution system includes a cylindrical housing defining a cavity. A mixture of water and ozone gas is delivered to the cavity, the mixture containing excess ozone gas. A cylindrical float is positioned centrally within the cavity to rise in accordance with the mixture column within the cavity. A piston is connected to move in accordance with the float. When the mixture level rises above a threshold, the piston the piston moves upward and seals an ozone outlet. As a pressure of ozone gas in the degassing chamber increases, the float is forced downward causing the piston to open a channel to an upper ozone outlet through which excess ozone gas is released. After removal of excess ozone gas, a mixture of water and ozone gas is output from the degassing chamber which is suitable for use as a general purpose cleaner.

Air disinfection device using ozone for killing bacteria and viruses with ozone recombination unit, comprising a housing (10), a fan (20), an ozone generator (50) included in the housing (10) and arranged in a separate box (30), the ozone generator (50) is electrically driven by a supply unit (41) connecting a high voltage to the ozone generator (50) to excite corona discharge, wherein a germicidal lamp (40) light is arranged in the box (30), and both the germicidal lamp (40) and the ozone generator (50) are driven by electric pulses having a frequency over 10 KHz, and an ozone recombination unit (60) is arranged behind the box (30) across the airflow passage to neutralize ozone included in the air flow that comprises at least two windings (63, 64) each having at least one surface comprised of respective spaced wires positioned across the airflow path and connected to a supply unit (61) coupling a pulsated high voltage with a repetition frequency over 10 kHz between the windings (63, 64).

A sterilization system includes a controller, a transformer including a primary side in communication with the controller and secondary side, an ozone generator in communication with the secondary side of the transformer and the controller, and a power source in communication with the controller, wherein the ozone generator ionizes atmospheric oxygen through the application of corona discharge.

An ozone injector device comprising a housing having a water passageway through the housing, a corona tube disposed within the housing, an ozone inlet fitting coupled to the water passageway, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube, and a clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet. The clearing piston is biased upwards, towards to the ozone inlet, and configured to prevent flow of ozone into the water passageway.
