The present invention provides a high efficiency discharge type ozone sterilization system to efficiently generate ozone for sterilization of heated air and maintain stable ozone concentration of heating air in the facility by discharging the air for the heating in the greenhouse or barn in a batch while circulating the air. The system comprises: an inner discharge tube which is located inside, has a fastening end unit capable of being screwed on both ends, extends to move a fluid in the longitudinal direction, and has three sections with separate outer surfaces (fluid inflow section, fluid acceleration section, and fluid outflow section)； an outer discharge tube which is fitted to the outside of the inner discharge tube and has a gap on the outer surface of the inner discharge tube to form a fluid flow path for moving the fluid； an outer heat dissipation means which is installed in contact with the outer surface of the outer discharge tube and has a plurality of heat dissipation fins protruding in an outer radial shape； a pair of fastening covers which is screwed in correspondence to both fastening end units of the inner discharge tube and fixes the outer discharge tube； and a grounding electrode means which has an inner electrode installed on any one of the fastening covers and grounded so that an electrode flows through the inner discharge tube, and an outer electrode coupled and installed to the outer heat dissipation means and grounded so that the electrode flows through the outer discharge tube.COPYRIGHT KIPO 2020본 발명은 온실이나 축사 내 난방을 위한 공기를 순환 유인하면서 일괄적으로 방전처리하여 가열공기의 살균에 필요한 오존을 효율적으로 생성시킴과 동시에 시설 내 난방공기의 적정 오존농도를 안정적으로 유지함을 제공하도록, 내측에 위치하되 양단에 나사 결합가능한 체결단부를 형성하고, 전후 길이방향으로 유체가 흐름 이동될 수 있게 연장 형성하되 외면이 구분된 3개의 구간(유체유입구간, 유체가속구간, 유체유출구간)을 형성하는 내부방전관과； 상기 내부방전관의 외측에 끼움 결합하되 상기 내부방전관의 외면에 간극을 두고 유체가 이동가능한 유체유동로를 형성하는 외부방전관과； 상기 외부방전관의 외면에 접촉상태로 설치되고 외측 방사형태로 돌출 형성된 복수 개의 방열핀을 구비하는 외부방열수단과； 상기 내부방전관의 양쪽 체결단부에 대응하여 나사 결합하고, 상기 외부방전관을 고정하는 한 쌍의 체결커버와； 상기 체결커버 중 어느 하
