This invention discloses an emulsifier with a passive rotating turbulence component, belonging to the field of fluid mixing. It includes a pipe body, within which a flow-guiding rotating component, an annular baffle, and a snowflake turbulence component are coaxially arranged along the fluid flow direction. By setting a flow-guiding rotating component consisting of a two-stage flow-guiding component and a passively rotating swirl impeller coaxially arranged within the pipe body, the axial flow of the fluid is transformed into a deflected flow with a tangential velocity component.

The original axial flow is transformed into a composite flow field coupling axial and rotating flows, significantly enhancing the local shear stress and flow field complexity, promoting the efficient breaking down and refining of large oil droplets. Combined with the multi-stage snowflake turbulence component after the flow-guiding rotating component, the emulsification effect is improved.
