The utility model provides an ozone discharge device integrates, thermal insulation board, ceramic discharge electrode paste the high voltage electrode intracavity at the integration cooling plate inproper order, the front of integration cooling plate sets up the high voltage electrode chamber, and the cavity is the seal positioning wall all around, back central authorities set up the degree of depth and are greater than 0 ionization chamber who is less than 0.3mm, set up a plurality of integrated air gaps location strip in the cavity, set up the cooling water passageway in the integration cooling plate. The utility model provides a discharge gap gas circuit long, take that effectively to discharge the area big, thereby it is big to cause the energy consumption, it is low that the unit discharges area ozone output, the high scheduling problem of material cost, make material consumption reduce by a wide margin, consequently the material cost of product reduces more than 30%, assembly and maintenance time practice thrift about 23, reduce energy consumption 45%, the high yield and the high concentration of ozone have been realized, can enough realize 150mgL's ozone concentration under lower energy consumption condition, satisfy the effective improvement requirement to high difficult degradation pollutant.
