Abstract:
An ozone generator comprising:at least one ozone-generating pipe including a hollow ground electrode, a high-voltage electrode situated inside the ground electrode to face thereto to form a discharge gap between the ground electrode and the high-voltage electrode, and a dielectric interposed in the discharge gap between the ground electrode and the high-voltage electrode;a feed gas chamber connected to one side of the at least one ozone-generating pipe,an ozonized gas chamber connected to the other side of the at least one ozone-generating pipe so that when an oxygen-containing feed gas is supplied to the at least one ozone-generating pipe through the feed gas chamber, the feed gas is subjected to silent discharge in the gap to cause the feed gas to change to an ozonized gas, which is then transferred to the ozonized gas chamber, andgas-permeable flame-propagation-preventing members arranged to sandwich at least the discharge gap therebetween and configured to prevent outward propagation of ozonized gas decomposition flame in case the flame is induced to the ozonized gas by spark discharge in the at least one ozone-generating pipe.
