The present invention relates to a plasma deodorization system comprising: a first chamber for feeding gas including odorous smells therein a first tube installed inside of the first chamber, and having multiple first inlets formed along the circumference thereof in a tangent direction with respect to an internal space, so the gas including odorous smells fed through the first inlets forms a vortex a plasma torch unit connected with the first tube, provided with the gas including odorous smells which forms a vortex, and producing plasma through the ignition of an ignition plug in oxygen and hydrogen sprayed therein by a spray nozzle so as to remove the odorous smells included in the gas a second tube connected with the plasma torch unit, having multiple second inlets formed along the circumference of a side connected with the plasma torch unit, and discharging the gas having the odorous smells removed therefrom by the plasma to the outside and a second chamber disposed in the outside of the second tube, and having multiple feeding pipes connected along the circumference thereof in a tangent direction with respect to the internal space, so the gas including odorous smells which is fed through the feeding pipes and forms a vortex also forms a vortex inside of the second tube through the second inlets and the gas is discharged while odorous smells are removed by the plasma. According to the present invention, by means of the vortex formation of gas including odorous smells and plasma treatment, an odorous smell removing effect is excellent, and high concentration odorous smells may be excellently removed.COPYRIGHT KIPO 2016본 발명은 악취 포함 기체가 내측으로 유입되는 제 1 챔버 제 1 챔버의 내측에 설치되고, 둘레를 따라 다수로 형성되는 제 1 유입구가 내측공간에 대하여 접선 방향으로 형성됨으로써 제 1 유입구를 통해 유입되는 악취 포함 기체가 와류를 형성하도록 하는 제 1 튜브 제 1 튜브에 연결되어 와류를 형성하는 악취 포함 기체가 내측으로 공급되고, 분사노즐에 의해 내측으로 분사되는 산소와 수소를 점화플러그의 점화에 의해 플라즈마가 형성되도록 하여 기체에 포함된 악취를 제거하는 플라즈마토치부 플라즈마토치부에 연결되고, 플라즈마토치부가 연결되는 측의 둘레를 따라 제 2 유입구가 다수로 형성되며, 플라즈마에 의해 악취가 제거된 기체를 외
