Abstract:
A compact lightweight air filtration system is disclosed. The air filtration system includes a hydrophobic particulate/coalescing filter and a cleanable ozone converter housed in a housing with an inlet and an outlet. Air flowing from the inlet to the outlet passes through the particulate/coalescing filter element and then the cleanable ozone converter to remove particulates, aerosols, liquids, and ozone.
Abstract:
A mobile system is described that that produces and applies an ozonated liquid to clean and sanitize a variety of articles and surfaces. The mobile system includes an ozonated liquid dispensing unit that forms the ozonated liquid from water and ozone gas.
Abstract:
An ozone generating apparatus includes a base container for holder water and a head assembly connected to the upper edge of the base container, the head assembly containing ozone generating cells, each having a dielectric tube and an electrode assembly coaxially disposed with the associated dielectric tube. The dielectric tubes and electrode assemblies are disposed and connected such that the tube and/or electrode assembly of each ozone generating cell can be accessed and replaced independently of all other ozone generating cells, and such that the possibility of cascade failure of all remaining ozone generating cells upon failure of a single cell is substantially eliminated.
Abstract:
An oxidation catalyst, an ozone injection nozzle, a urea-based fluid injection nozzle, and a selective reduction catalyst are arranged in an exhaust pipe of an engine in this order towards its outlet. An exhaust gas purifier includes an air flow sensor that detects an air intake amount of the engine, a NOx sensor that detects a NOx concentration in the exhaust pipe, and first and second temperature sensors that detect inlet temperatures of the catalysts. An ozone generation device to which the ozone injection nozzle is connected includes a compressor, a dryer that dries compressed air, a flow rate sensor that detects a flow rate of this air, an ozone generator that converts this air into ozone, and an ozone concentration sensor that detects a concentration of the ozone. A controller controls the compressor and the ozone generator based on respective detection outputs of the respective sensors.
Abstract:
An ozone generator includes a housing having an internal cavity and a plurality of electrode pairs located in the internal cavity. The electrode pairs each contain two electrodes arranged at a distance of a predetermined gap length, and a discharge space is formed between the two electrodes, whereby ozone is produced when a source gas flows at least between the two electrodes and a discharge is generated between the two electrodes. The ozone generator has a non-discharge portion in an arbitrary cross-section having a normal direction parallel to a main flow direction of the source gas in the internal cavity.
Abstract:
A portable, personal advanced-oxidation water treatment system based on ozone and a catalyst such as titanium dioxide that can cycle and purify water to make it portable by removing organic contaminants. The unit can be used for long periods of time without having to replenish the active portions. The unit can be carried in a backpack or in a vehicle. Fresh water is typically loaded into the unit, and the unit is cycled until the water is pure enough to drink. A battery is used to produce ozone and to cycle the water through a reaction vessel and can optionally be charged with a small solar panel The unit can also be powered directly from a vehicle.
Abstract:
A dielectric assembly for generating ozone includes a positive electrode, a negative electrode, a dielectric for generating the ozone, and a knob adapted to extend outside of a housing into which the dielectric assembly is to be placed. A system is also provided for sanitizing and deodorizing water, food, surfaces and air including a microbiological reduction filter device having an input connected to a water supply, a venturi injector disposed within a housing and connected to an output of the microbiological reduction filter device which generates ozone and mixes the generated ozone with the water, and an electrode assembly comprising a plurality of electrodes, a dielectric for generating the ozone, and a knob extending outside of the housing. The dielectric in a first embodiment and the entire dielectric assembly in a second embodiment can be removed from the housing and replaced in its entirety by the knob.
Abstract:
There is described herein a direct current power supply which offers improved control over an output signal. An input signal generated by an alternating current source is received and chopped by a solid state relay. The chopped signal is rectified by a bridge rectifier before being filtered by an “LC” (induction coil-capacitor) or “CLC” (capacitor-induction coil-capacitor) filter. The output signal can then be used as a direct current power supply signal. This power supply may be used in various types of ozone generation systems.
