Cavitation type high-vacuum separation method

The invention discloses a cavitation type high vacuum separation method, which relates to the field of cavitation separation, and comprises the following steps: S1, crude oil transportation: crude oil is conveyed into a heater through an oil inlet pipe; s2, crude oil heating: the crude oil is heated by a heater, and the heated crude oil is conveyed into a coarse filter; s3, coarse filtration of impurities: large-particle impurities in the crude oil are filtered by a coarse filter, and the crude oil subjected to coarse filtration is conveyed into a vacuum tank; and S4, oil-water separation: carrying out oil-water separation on the crude oil in the vacuum tank by the vacuum separator, simultaneously discharging holes mixed in the crude oil, conveying the separated pure oil into a fine filter by the vacuum tank, and atomizing the oil under high vacuum and low temperature. Crude oil is subjected to heating, rough filtration, oil-water separation and fine filtration, so that cavities in the crude oil are discharge
