Abstract:
An ozone generator for generating ozone by applying a specified process to oxygen by discharge includes a first raw material gas supply unit for supplying the oxygen as a first raw material gas, and a second raw material gas supply unit for supplying an oxide compound gas as a second raw material gas, in which, by excited light, excited and generated by a discharge in the oxygen and the oxide compound gas, the oxide compound gas is dissociated, or the oxide compound gas is excited accelerating dissociation of the oxygen, and ozone is generated. In this way, ozone generation efficiency is raised.

Abstract:
The present invention discloses an ozone generator with reduced NOx comprising an air stream generating means; a drying means; an electrical field generating unit; a high-voltage generating means; and a cooling means. The flow velocity of the air stream in the ozone generating area can be increased by means of the air stream generating means up to 700 s.c.c.m, The temperature in the ozone generating area can be lowered by means of the cooling system to lower than 10null C. By means of the above, the amount of NOx produced by the disclosed ozone generator can be reduced substantially.
Abstract:
There is provided a highly efficient and compact ozone generating apparatus in which a very short air gap of about 0.2 mm is formed at high accuracy. Non-discharge portions are dispersed and disposed to cover an entire discharge space, or a spacer is provided to form the non-discharge portion. Further, an elastic body is mounted on a back face of an electrode, thereby enhancing an air gap accuracy of the discharge space.
Abstract:
The present invention relates to a tubular ozone generator which uses a novel electrode structure wherein a wound electrode has a solid insulator between the turns of the windings.
Abstract:
A surge suppression system for dampening surge pressures or pipe hammer by introducing a gas into a flow conduit in such an amount that the introduced gas is in excess of that required to saturate the liquid. Preferably, the gases are those which are relatively inert or not unduly reactive and which possess relatively low saturation levels with respect to the liquid. Desirably, the gas is added through a member to the flow conduit in a vicinity of high turbulence. The surge suppression system can be utilized in generally any liquid system and particularly in a liquid transmission system.Another embodiment pertains to a scrubber or washer for generally purifying gases and may contain one or two stages to efficiently remove impurities as through the use of high solubility fluids, fluids which decompose contaminants or which contain or provide (i.e. heating stage) catalysts to decompose contaminants, oxidizing agents, or reducing agents. The scrubber contains a packed bed and the packing may be characterized as one where the inside hydraulic radius equals the hydraulic radius of the external flow channels. The washer or scrubber type apparatus is particularly suitable for treating (purifying) materials such as ozone utilized in a deodorizing or disinfecting system.Another embodiment pertains to the purification of a gas by treatment with a fluid in a flow conduit having a plug flow at its entrance containing an injection-mixing device coacting with a first high turbulence causing device and a downstream or second high turbulence causing device. The treating fluid is preferably added at the vena contracta of the first high turbulence causing device.

Abstract:
A gas pipe integrated block includes a plurality of internal pipe paths. The plurality of internal pipe paths are connected to a nitrogen-free ozone generator in which a photocatalytic material for generating ozone is applied to a discharge surface, a controller (an MFC, a gas filter, and an APC), a raw material gas supply port, and an ozone gas output port. Thereby, a raw material gas input pipe path extending from the raw material gas supply port through the APC to the nitrogen-free ozone gas generator, and an ozone gas output pipe path extending from the nitrogen-free ozone generator through the gas filter and the MFC to the ozone gas output port, are formed in an integrated unit.
Abstract:
A selective catalytic reduction catalyst capable of reducing the NOx in exhaust gas to N2 is arranged in an exhaust pipe of an engine. Fluid feed means has a fluid injecting nozzle facing the exhaust pipe on the exhaust gas upstream side from the selective catalytic reduction catalyst. The fluid feed means is configured such that a urea fluid that functions as a reducing agent is fed with the selective catalytic reduction catalyst from the fluid injecting nozzle to the exhaust pipe. Ozone feed means includes an ozone injecting nozzle that faces the exhaust pipe on the exhaust gas upstream side from the selective catalytic reduction catalyst, and on the exhaust gas upstream side or the exhaust gas downstream side from the fluid injecting nozzle. The ozone feed means is configured such that ozone is fed from the ozone injecting nozzle to the exhaust pipe.
