The invention provides a whirl enhanced vertical oil water separating device with micro-channels and relates to a multi-whirl oil water separating system. The whirl enhanced vertical oil water separating device comprises a motor, an entrance section, a separator main body, a deep separating section, an oil collecting weir plate, an oil outlet section, a water outlet section, a whirl enhancing section, a pre-separating section and a transmission shaft. The whole set of separating device has a vertical structure; the separator main body comprises the pre-separating section, the whirl enhancing section and the deep separating section; the motor is connected with the whirl enhancing section through the transmission shaft and is used for driving the whirl enhancing section to rotate; the entrance section is arranged at the top of the pre-separating section; a large amount of micro-channels are arranged in the whirl enhancing section; an oil outlet section and a water outlet section are arranged at the bottom of the deep separating section. The whirl enhanced vertical oil water separating device with micro-channels can be used for reducing the equipment space occupation, increasing the applicable range of handling capacity, greatly increasing the oil water separating efficiency, effectively avoiding secondary mixing phenomenon of separated oil and water and realizing the deep separation of oil and water.
