OZONE GENERATOR Russian patent published in 2013 - IPC C01B13/11 

FIELD: chemistry.

SUBSTANCE: apparatus has, inside a sealed housing, high-voltage and earthed plate electrodes having centre holes and capable of being cooled with a coolant, coated on the outside with a dielectric and alternating with each other, a power supply whose terminals are connected to the electrodes, nozzles for feeding an oxygen-containing working gas and coolant and nozzles for removing the coolant and the gas/ozone mixture. The electrodes are made from airtight-connected parallel plates which form an inner cavity which holds crosspieces arranged perpendicular to the inner surfaces of the electrode plates and rigidly connecting the plates to each other, and nozzles for feeding the coolant to the electrodes and removing the coolant from the electrodes. The electrode plates have parts which protrude beyond the active zone. The first inner crosspiece and all odd crosspieces are rigidly attached to one electrode plate, and all even support crosspieces are rigidly attached to another plate. On the outer edge of the annular plates there are semi-cylindrical cavities for passage of locking rods which, by passing through holes in the support crosspieces, connect the annular plates and provide a rigid electrode structure. Three rods, lying at an angle of 120° to each other, go beyond the outer edge of the electrode and are elements for mounting the electrode to support posts, having holes for insertion of electrode mounting rods, lying at a certain distance from each other.

EFFECT: improved purification.
