Above-mentioned a kind of waste grease prepares the high-shear emulsifying reaction unit of biodiesel, comprise that also one is arranged at the mulser of reactor outside, described mulser comprises motor, mulser outer cover, described mulser outer cover is sleeved on described mulser and puts outward, described mulser is enclosed in the described mulser outer cover center cavity, described mulser outer cover one end is communicated with described reactor by pipeline, and the other end is communicated with described reactor by pipeline.
Above-mentioned a kind of waste grease prepares the high-shear emulsifying reaction unit of biodiesel, and the diametric angle of the center line of the perforation direction of the set penetrating groove of rotor and described rotor arc surface joining is 0 °-80 ° on the rotor of its described mulser.
Above-mentioned a kind of waste grease prepares the high-shear emulsifying reaction unit of biodiesel, the rotating speed of its described mulser greater than: 500 rev/mins.
Technique effect of the present utility model is: add mulser on original biodiesel consersion unit.Material is under the rotating speed of mulser more than 500 rev/mins, by the centrifugal action that rotor produces, from the gap of radially getting rid of narrow precision between the stator and rotor, be subjected to shearings of strong machinery and fluid power, centrifugal extruding, liquid layer friction, clash into and tear and comprehensive function such as turbulent flow.Stir the laminar flow that is produced with traditional blade mechanism and compare, material has reached intermolecular abundant contact and mixing, thereby has accelerated reaction rate under the effect of mulser, has shortened the reaction time, has reduced reaction temperature.
