Abstract:
An ozonizer discharge cell, comprising:a pair of planar electrodes separated by a dielectric to ozonize a material gas circulating through a discharge space formed between one of said planar electrodes and said dielectric by means of discharge; andsaid dielectric comprising at least one ceramic block including a plurality of ceramic layers integrally superimposed on each other in a layer thickness direction,wherein said at least one ceramic block includes a gas introduction route and a gas discharge route passing through said plurality of ceramic layers in said layer thickness direction and communicating with said discharge space,wherein said at least one ceramic block includes a coolant introduction route and a coolant discharge route passing through said plurality of ceramic layers in said layer thickness direction and communicating with a coolant circulation route,wherein the coolant circulation route is insulated from said planar electrodes by an insulating ceramic layer disposed between said coolant circulation route and said planar electrodes,wherein said at least one ceramic block comprises two ceramic layers and an intermediate ceramic layer disposed between said two ceramic layers, andwherein said discharge space is formed between said two ceramic layers.
