Abstract： The Kenics static mixer can promote the mixing of associated gas and hydrogen，and its structural parameters need to be further optimized in order to ensure the combustion safety of the mixed gas.Therefore， orthogonal experiments were designed and computational fluid dynamics software Fluent was used to simulate the effects of the number of diversion components，component distortionangle and vertical angle between diversion components on the mixing uniformity of Kenics static mixer（KSM），and the optimal structural parameters were obtained. The results show that the three factors have great influence on the mixing uniformity，the influence magnitude is： the number and length of components > the torsion angle of components > the vertical angle of components. The mixing non-uniformity decreases with the increase of the number of diversion components and the increase of the component torsion angle，and increases with the increase of the verticalangle of diversion components，showing a trend of first rising and then decreasing.The optimal structural parameters of the mixer are as follows： when the number and length ofthe diversion group are12×30mm ，the torsion angle of the component is 270∘ ，and the vertical angle of the componentis 90∘ ，the mixing non-uniformity is the lowest 0.23% .The research results can provide technical reference for the structure design of static mixer with high mixing uniformity in the background of hydrogen mixing.
