Embodiment: Referring to Fig. 1, Fig. 2 and Fig. 3, a mobile lubricating oil three-field combined dehydration device includes a vehicle frame 1, and the vehicle frame 1 has four casters 19, thereby making the movement of the entire device more convenient, fast. The vehicle frame 1 is provided with an equal pressure feed distributor 2 and several swirlers 3, and the cyclone 3 is connected with the equal pressure outlet of the equal pressure feed distributor 2 at the same time; to simultaneously treat more oil treatment, thereby improving the dehydration efficiency of the entire device. During specific implementation, a pressure gauge 18 is provided on the pressure equalizing feed distributor 2 to monitor the oil pressure in real time and ensure the working pressure of the cyclone 3 to achieve the best separation effect. The number of said swirlers is 4, and adopts a parallel oblique installation curve configuration. When in use, the inlet of the pressure equalizing feed distributor 2 is connected to the chemical pump through a pipeline, so that the lubricating oil to be treated is sent into the equal pressure feeding distributor 2 at a certain pressure, and then the lubricating oil to be treated is fed by the distributor. Evenly distributed to each cyclone 3 of the cyclone 3 group, this can ensure that the inlet pressure of the cyclone 3 is stable, so as to achieve the best separation effect. The lubricating oil liquid enters the cyclone 3 tangentially, producing a strong three-dimensional elliptical strong rotational shear turbulence movement, due to the particle size difference (or density difference) between coarse particles (or heavy phase) and fine particles (or light phase) ), the centrifugal force, centripetal buoyancy, and fluid drag are different in size. Due to the action of centrifugal sedimentation, the components with high density in the mixture move downward in the axial direction and outward in the radial direction under the action of the swirl field. After reaching the cone section, it moves down along the wall and is discharged from the bottom flow port, thus forming an external vortex flow field; the components with low density move toward the central axis, and form an upward moving inner vortex at the center of the axis. Vortex, then drain through the overflow.
