Abstract:
The present invention provides an air filtration cartridge (1) suitable for use in the treatment of air in a forced airflow air supply system. The cartridge (1) comprises an inner casing (2) having an upstream stage (3) defining a chamber (4) having an inlet (5) for receiving a forced airflow (6). The chamber (4) has an outlet (7) which leads into a downstream stage (8) comprising a filter holder and mounting a high airflow electrostatic filter. Inside the chamber (4) is a low power coronal discharge ozone generator device (10).
Abstract:
The invention relates to a pulsed electric field sanitization system that may be used for sanitization of liquids, such as drinking water. The system optionally includes a double check valve to allow simultaneous flow of water into and out of components of the system. The system may be used in combination with other purification technologies. A further embodiment of the invention relates to a stand-alone drinking water purification device.
Abstract:
The present invention relates to a device and a method for generating ozone in exposing air or oxygen (6) for high tension voltage in an ozone generating device (1) comprising at least one unit (9) have plane or cylindrically formed ceramic elements (4, 4’) with electrodes (2) and an earth plane (3) situated outside said elements. In said device (1) and according to the method the air and oxygen (6) respectively, which surrounds the elements (4, 4’), is exposed to an over pressure of about 2,5 atmosphere gauge during the generation of ozone (5) at the same time as the cooling liquid (7), which is situated in the cooling device (8), is exposed to an over pressure, which at least extends to the same value as that of said air and oxygen respectively.
Abstract:
An ozone generator has a dielectric element, first and second opposed end cap members and a gas passageway positioned between a high voltage electrode and a ground plane and positioned internal of the dielectric element, and at least one securring member extending between the opposed end caps whereby the securring member holds the end caps in place.
Abstract:
Corona discharge cells for the production of ozone are respectively constructed of inner electrodes (1) fabricated from metal bar, a dielectric sleeve (4) and outer electrodes (5). Spacers and/or sealing rings (3) isolate a corona discharge producing region (S) from ambient conditions. Hollow bores (31, 32) in the inner electrode (1) may access an air space between the electrodes between the spacers (3). The surfaces of the inner electrodes can be roughed to enhance ozone production within the corona discharge producing region.
Abstract:
Ozone is generated in ozone generator (10) and combined with water from source (40) in container (50). The combined water and ozone are then mixed in inline mixer (56) and transported to unit (68) to provide a substantially homogeneous mixture, and a confined flow path having a length sufficient to provide substantially complete decomposition of the ozone.
Abstract:
The present invention relates to an apparatus and a method for ozone generator and a method for generating ozone by exposing oxygen to a high frequency alternating current with high voltage over a dielectric. In order to provide a simple, compact and low cost design, capable of increasing the power and improving the conversion efficiency of the apparatus, and to prevent the apparatus from damage or efficiency decrease, the apparatus comprises a pressure compensation admitting unit, joint together by at least two plates (2, 2') of a dielectric material and there between a present electrode (4), on which a high frequency alternatively current with high voltage is applicable, and two sealed spaces (1, 1') for generation of ozone on opposite sides of said unit (1, 2', 4), whereby the respective sealed space (1, 1'), on the opposite side of said plate (2, 2') of dielectric material, is delimited by an earthed and cooled electrode (3, 3'), through which oxygen gas or gas rich in oxygen is supplied to the space (1, 1') and ozone is conducted out of the same. By means of this apparatus oxygen gas or gas rich in oxygen can, according to the method of the present invention, be conducted under pressure into the sealed chambers (1, 1') on opposite sides of the pressure compensation admitting unit (2, 2', 4).
Abstract:
The invention relates to an ozone generator with a capacitor arrangement of two electrodes (20, 22), i.e. an outer, substantially tubular external electrode (22) and an internal electrode (20) fitted inside it, between which there is a tubular dielectric (24) on the one hand and a space (26) on the other, through which the oxygen-containing gas to be ozonised flows. The internal electrode (20) has a cross-section which: a) has a regular, continuously circulating outer contour; b) has a rotation symmetry and c) has convex and continuously curved ends (30) which are at the greatest distance from a centre (36) of the internal electrode (20) and beside which there are depressions (32).
Abstract:
The energizer (10) includes an electric discharge apparatus (14) for creating an electric discharge and a focusing mechanism (40) for focusing the electric discharge on a fluid to be energized. In a preferred embodiment of the invention, the focusing mechanism takes the form of a dielectric core (40) which is constructed and arranged to focus the electric discharge into a passage formed about the periphery of the core (58) thereby enabling the use of energy levels substantially higher than would be possible without the focusing means (40). A method of energizing a fluid is taught which includes introducing the fluid into a confined region, providing an electric discharge for energizing the fluid and focusing the discharge into the confined region.
