Abstract:
A reactor produces a surface corona for emitting UV light and for the production of ozone by passing air or oxygen through the surface corona. The emitted UV light activates a photocatalyst coated on a surface facing a surface with embedded electrodes which generate the surface corona. The photocatalyst is a thin film of nanoparticle TiO2 with primary particle size of 0.02 to 0.2 μm was deposited on a substrate by a flame aerosol method. The method combines ozonation and photocatalysis to provide effective and efficient oxidation of alcohols and hydrocarbons to value added products. The method can also be used for air and water cleaning.
Abstract:
An air conditioner device includes a first electrode array and a second electrode array. A mechanism, that cleans the electrode(s) in a first electrode array, includes a length of flexible insulating material that projects from a base of the second electrode array towards the first electrode array. As a user moves the second electrode array up or down within the conditioner housing, the electrode(s) in the first array are frictionally cleaned.
Abstract:
Systems and methods are provided for compensating for variations in line voltages the power an electro-kinetic air transporter and conditioner device. The electro-kinetic air transporter and conditioner device includes a high voltage generator that provides a potential difference between at least one emitter electrode and at least one collector electrode. The high voltage generator is driven by both a DC voltage obtained from an AC voltage source, and a low voltage pulse signal. The DC voltage is stepped down to produce a voltage sense signal indicative of a level of AC voltage source. The voltage sense signal is monitored. At least one of a pulse width, duty cycle and frequency of the low voltage pulse signal is adjusted, based on the monitored voltage sense signal, in order to substantially maintain the potential difference at a desired level.
Abstract:
The Diffusive Plasma is for effective treatment of contaminated air and material processing. Air is purified and disinfected by passing through the diffusive plasma device which includes a reactor or a plurality of reactors arranged in parallel or series and is energized by a high voltage alternating current power supply. The diffuser, being electrically isolated, provides extra nucleation sites to initiate discharges. It serves to improve the generation of uniform and consistent plasma and to reduce the variation of discharge properties among the reactors. The addition of a diffuser, thereby, enhances the overall effectiveness of decomposing chemicals and destroying microbes to achieve high air treatment and material processing performance. The diffuser can be made of suitable filtering materials to additionally serve as a filter. By incorporating suitable catalytic materials with the diffuser, the reactor becomes a catalytic plasma reactor wherein the plasma environment provides enhanced catalytic functions. Effective plasma power deposition may be obtained by controlling the amplitude, waveform period and shape of the voltage applied to the electrodes of the reactor and hence the operation of the reactors with plasma discharged of selected conditions for optimizing the treatment and processing efficiency while minimizing the generation of unwanted bi-product gases. The present invention also relates to a method for effective air treatment and material processing.

Abstract:
An ozone generator in which a discharge region may be enlarged without damaging ozone generating performance. In the ozonizer, an alternating current is applied between a first electrode and a second electrode, and a discharge is produced in a gap into which oxygen is injected. In the first electrode, an ozone gas passage for retrieving ozone gas generated in the discharge region is located between an electrode surface facing the discharge region and a side. The ozone gas passages are dispersed in the first electrode. The ozone gas passages collect ozone generated at discharge region locations inside the first electrode.

An improved corona generator structure includes a ground tube body sheathed within an insulating sleeve. One end of the ground tube body is provided with a sealing lid for being firmly coupled to the end portion of the ground tube body. At least one piece of high voltage electrode plate is coupled with the insulating sleeve. The high voltage electrode plate is provided with a plurality of spacers for allowing a gap of a substantially equal height to be formed between every area of the high voltage electrode plate and the insulating sleeve so as to uniformly distribute the corona on the high voltage electrode plate when electricity conducts therethrough. Furthermore, the two retaining sleeves are coupled to both end portions of the high voltage electrode plate and the insulating sleeve such that the high voltage electrode plate is firmly positioned on the insulating sleeve. By means of exposure of the high voltage electrode plate, a user can detach and wash the corona generator quickly and achieve efficacy of heat dissipation.

This is a discharge cell used for an ozonizer. A space where a discharge gap amount is determined between the first electrodes 10 and 10 is formed by stacking a couple of upper and lower first electrodes 10 and 10, constituted by the plate-like rigid body, in both sides with sandwiching a couple of rigid body spacers 20 and 20. In this space, a dielectric body unit 30 that consists of a rigid body of the sandwich structure of sandwiching a second electrode 32 is arranged between glass plates 31 and 31. The dielectric body unit 30 is supported in a neutral position in the space by a plurality of spacers 40, 40, . . . for discharge gap formation that are inserted between the upper and lower first electrodes 10, and forms discharge gaps 50 and 50 in both sides. The minimum discharge gap amount G of 0.4 mm or less is stably secured. It is possible to prevent the damage of a cell component and a pressurizing mechanism.
