Abstract:
The power supply unit for an ozone generating system generally has a pulsed current generator generating current pulses to be supplied to an ozone generator; and a computer adapted for obtaining an ozone yield based on a first amount of ozone to be generated by the current pulses during a first period of time and on a first amount of electricity consumed by the power supply unit during the first period of time; modifying an amplitude of the current pulses based on the ozone yield; obtaining an ozone production rate based on a second amount of ozone generated during a second given period of time; adjusting a frequency of the current pulses based on the ozone production rate; and wherein said steps are executed iteratively to enhance the ozone yield while meeting the ozone production rate.
Abstract:
An ozone liquid converter (1) which converts a liquid held in a sealed vessel (3) provided with a septum (51), into ozone liquid including: a liquid tight passage (5) in which to both ends of a passage main body (7) thereof, there are respectively connected insertion needles (35,33) for liquid discharge and liquid return in an internally communicating state; an ozone gas entrapment part (11) which is arranged part way along the liquid tight passage (5); and an ozone gas discharge part (27) which is arranged part way along the liquid tight passage (5), and on a downstream side of the ozone gas entrapment part (11), and which discharges ozone gas which has not dissolved in the liquid, to the outside of the pathway; wherein said liquid tight passage (5) and said sealed vessel (3) are connected by puncturing said septum (51) with said insertion needles (35, 33), and there is formed a liquid circulation passage in which liquid flowed out from said sealed vessel (3) passes through said liquid tight passage (5) and returns to said sealed vessel (3), and ozone is dissolved, in said ozone gas entrapment part (11), in the liquid which has flowed out from said sealed vessel (3) to said liquid tight passage (5), and converted to ozone liquid, and after discharging the ozone gas what has not been dissolved in said ozone gas discharge part (27), said ozone liquid is returned to inside said sealed vessel (3), to thereby convert the liquid contained in said sealed vessel into ozone liquid.

An ozone generator is provided with a pulse generator (110) that at least includes pulse generation means for generating a pulse voltage and a magnetic switch (SI2) adjusting pulse width of the generated pulse voltage, and a discharge reactor that is provided with a plurality of electrodes to which the pulse voltage for which the pulse width has been adjusted is applied, and that generates a discharge between the plurality of electrodes as a result of the pulse voltage, for which the pulse width has been adjusted, being applied thereto, and also generates ozone as a result of a raw material gas containing oxygen being supplied from the outside to between the electrodes where the discharge has been generated.
Abstract:
Very low density ozone is generated by corona discharge on dual side of ceramic plate (dielectric medium) with mesh on both the side of ceramic plate contained in the stainless steel box which is duct mounted in HVAC ducts by applying control voltage & low frequency not exceeding 50 Hz over both sides of ceramic ozone plates for overall reduction of VOC in occupied spaces in indoor air quality. The air flow over the ceramic plates will be horizontal & vertical. So for generation of ozone no extra air preparation is required. Voltage to the ozone plates is varied in accordance with the VOC in occupied space to maintain the VOC at the minimum level. Safety measures for high ozone & VOC sensor cable breakage protection is considered with AHU fen interlock.
Abstract:
The invention provides a power supply apparatus for supplying electric power to a capacitive load. The apparatus has a transformer, a positive half-period driver and a negative half-period driver supplying positive and negative half-periods of voltage to the first coil. The second coil forms an electric resonance circuit and supplies electric voltage to the load. Zero crossings of the voltage supplied to the first coil are determined from a third coil on the transformer, and alternation between positive and negative half-periods of voltage supplied to the first coil is done at the zero crossings of the voltage supplied to the first coil.
Abstract:
For the purposes of environmental protection, it is increasingly necessary to remove nitrogen oxides from an air flow at an ambient or outer air temperature. While NO2 can be separated from a gas flow by means of methods known per se, whereby the carbon is washed out or absorbed, it is not possible to separate NO using said methods. Hitherto known methods exhibit deficiencies that make it impossible to use them on a widespread scale. The present invention solves this problem in a simple and inexpensive manner. Short pulses lasting up to a few nanoseconds allow for higher electrical voltages inside the ionizer (4) than direct current, without resulting in electrical flashovers. Tests have shown that ozone is formed inside the gas flow to such an extent that nitrogen monoxide present in said gas flow is substantially oxidized. The NO2 formed in the ionizer can subsequently be removed from the gas flow using a known method. A further advantage of the invention is that a pre-ionizer can be arranged upstream from said ionizer, whereby gas molecules and particles can be electrically charged before they enter the ionizer. The filter system to which claim is laid can also be used without a separator for NO2 for the separation of particles only from a gas flow. One particularly advantageous application of the invention is the use thereof in the removal of smoke, especially smoke emanating from fires, from a flow of air or gas.
Abstract:
A novel type of power supply for AC discharge by which the discharge is easily performed even when insulators adhere to electrodes or the gas pressure drops and variation of plasma parameters with time is very small. A power divider (2) divides a signal from a master oscillator (1) into a plurality of signals and phase shifters (3) and power amplifiers (4) respectively determine the phases and amplitudes of the divided signals. A controller (7) controls and adjusts the oscillation frequency, and the phases and amplitudes of the divided signals. The final outputs are produced through transformers (5) and fed to a plurality of electrodes (6) arranged in a discharge enclosure. The transformers (5) are connected to each other on the output side by one of their outputs which are normally maintained at a floating potential, and discharge is made to take place between the electrodes (6). The phases and amplitudes of the electrodes (6) are arbitrary and may be the same respectively. The phases are controlled and the amplitudes are adjusted most appropriately to the controlled system. In addition, the shapes and arrangement of the electrodes (6) are also arbitrary and made appropriate to the system.
