An ozone generating apparatus having high reliability in which a glass tube can prevent from being damaged by melting a power feeding brush even if a large amount of short-circuit current flows. In an ozone generating apparatus using silent discharge, an alternating high voltage power is supplied from a power supply to a metal film formed in an inner wall of a glass tube by a power feeding brush comprising a brush shaft made of metal and a large number of metal thin wires fixed to the periphery of the brush shaft, the following equation satisfies. (D2/D1)≧(1+(1/20 β)), wherein ‘D1’ indicates an outer diameter of a bundle of metal thin wires, ‘D2’ indicates an outer diameter of the brush shaft and ‘β’ indicates the line density of metal thin wires on a surface of the brush shaft.

摘要:
Gas treatment equipment includes a compressor which compresses process gas, a first process module which is disposed downstream of the compressor and which treats the process gas, an expander which is disposed downstream of the first process module and which expands the process gas to obtain power, a second process module which is disposed downstream of the expander and which treats the process gas, and a driver which drives the compressor. A first pressure indicator is disposed at an inlet of the compressor for the process gas and measures a pressure of the process gas, and a second pressure indicator is disposed at an outlet of the second process module for the process gas and measures a pressure of the process gas. A recirculation flow path is connected to both of the outlet of the second process module for the process gas and the inlet of the compressor.
