The invention relates to an emulsifying method and device by double-vortex-body vortex. Two or more fluids (liquids or gases) which can not be mixed together, such as oil and water, simultaneously flow through a double-vortex-body vortex generator, make a double-vortex-body centripetal vortex motion and are discharged from the lower end to form an emulsion. The double-vortex-body vortex generator is formed by connecting a main body container and a spiral double-vortex-body vortex tube, wherein more than one feed port distributed around the circumference in the same tangential direction is arranged around the circumference of the main body container; and the bottom end of the double-vortex-body vortex tube is a small-diameter end used as a discharge port. A fluid flows in through a tangential feed port of the main body container to form a centripetal vortex motion; and the fluid flows through the double-vortex-body vortex tube on the lower part to form a double-vortex-body centripetal vortex motion and is coherent with vacuum zero point energy to form a double-vortex-body centripetal vortex internal pressure field, and the field acts on the fluid flowing through the double-vortex-body vortex tube to form a better double-vortex-body vortex emulsion.
