Abstract

A plate-type ozonizer capable of suppressing the deformation of plate discharging cells and securing a high ozone-generating efficiency where a high-concentration and high-pressure ozone gas is to be generated. An ozonizer body 10, in which a plurality of discharging cells 11 are stacked one above the other, is housed in a pressure vessel 20. The pressure vessel 20 is supplied with a pressurized gas having a pressure equal to or almost equal to that of the raw material gases which are supplied to said discharging cells 11. Thus, there is little or no differential pressure between the inside and the outside of the discharging cells 11 and therefore the discharging cells 11 are not subject to being deformed by unequal inner and outer pressure forces. A dried gas is used as the pressurized gas to also prevent poor insulation due to a dewing or condensation.
