摘要:
In an electric discharge type ozonizer using highly pure oxygen gas having a purity of not lower than 99.99% as a raw material gas, the pressure of a gas in the discharge space of a discharger is raised to a level higher than atmospheric pressure by at least 1.1 kgf/cm² and/or in which a liquid-cooled discharger is used, and the temperature of the cooling liquid is set at a level not lower than 15°C, whereby the ozonizer is capable of stably producing ozone gas at a high ozone concentration without causing lowering of the ozone concentration with time.

摘要:
The present invention provides a method for deodorizing and refreshing petroleum group solvent used in a dry cleaning apparatus, and a dry cleaning apparatus using such a method, which can maintain the circulating solvent in a fresh condition for a long time, eliminate a bad smell of the solvent, provide highly stable cleaning ability and good cleaning finish, and prevent ignition and explosion of the solvent to ensure safety. In the dry cleaning apparatus, the petroleum group solvent in a solvent storage tank 2 is pumped by a circulating pump 5, is supplied to a cleaning bath 8 through a filter 6 and carbon absorbent 7 and then is returned from the cleaning bath 8 to the solvent storage tank 2 through a button trap 3, and an ozone generating device 10 is provided for generating ozone gas and a diffuser 11 for pouring the ozone gas produced by the ozone generating device 10 into the petroleum group solvent as fine bubbles are arranged to be contacted with a bottom surface of the solvent storage tank 2 or the button trap 3.
摘要:
A discharge reactor that generates silent discharge and/or creeping discharge between dielectric and high voltage electrode and/or grounded electrode, said dielectric being located between high voltage electrode and grounded electrode, and which generates clean ozone in the discharge space 1 as it passes through said discharge space 1 or as it is held within said discharge space 1, which discharge reactor is characterized in that the dielectric is made of highly purified quartz glass (SiO₂) or single-crystal sapphire which is a highly purified crystallized aluminium oxide or high-purity alumina ceramics which is the firing of highly purified aluminum oxide. Further, in order to obtain cleaner and highly concentration ozone, at least the electrode or electrodes in the area of the discharge space which is to be exposed to discharge are made of a high-purity aluminum material and at least the area of the discharge space which is to be exposed to discharge is further coated with an anodic oxidation film.
摘要:
An ozone generator comprises a pair of spaced opposing electrodes, electrically conductive members connecting the pair of electrodes to a high-voltage alternating-current power source to generate an electric discharge between the electrodes, a dielectric provided between the opposing electrodes, and a gas flow passage for effecting flow of a material gas defined by the surfaces of the electrodes. At least one of the surfaces of the pair of electrodes has a plurality of parallel grooves. The material gas flows in a space between the plurality of grooves and the dielectric, in a direction transverse to the grooves.
