Claim 2:
3. The separation device with two-stage gas-liquid mixture and conical spiral fields according to claim 1, wherein the first-stage uniform mixer is configured to perform the process of the first-stage gas-liquid crushing and uniform mixing by the outer micropore ceramic pipe, the middle micropore ceramic pipe and the inner micropore ceramic pipe; bubbles of relatively large size in the gas-liquid two-phase flow are crushed into smaller bubbles; the first-stage mixing pipe is longer than the liquid inlet buffer pipe; a bottom of the liquid inlet buffer pipe is provided with the lower liquid inlet flange for sealing; and a round hole is drilled in a center of the lower liquid inlet flange;
the upper partition plate and the lower baffle plate are both circular steel plates, cross sections of the annular clamping grooves of each of the upper partition plate and the lower baffle plate are in right trapezoid shapes; the inner flow guide holes uniformly distributed in a circumferential direction of the partition plate are provided between an inner one of the annular clamping grooves of the upper partition plate and a middle one of the annular clamping grooves of the upper partition plate in a radial direction of the upper partition plate; the outer flow guide holes of the upper partition plate uniformly distributed in the circumferential direction of the upper partition plate are provided on an outer edge of an outer one of the annular clamping grooves of the upper partition plate in the radial direction of the upper partition plate; the flow guide round hole is drilled in a center of the lower baffle plate; the flow guide holes of the lower baffle plate uniformly distributed in a circumferential direction of the lower baffle plate are provided between an outer one of the annular clamping grooves and a middle one of the annular clamping grooves of the lower baffle plate in a radial direction of the lower baffle plate; first outer side walls and first inner side walls of the flow guide holes of the lower baffle plate in the radial direction of the baffle plate, second outer side walls and second inner side walls of the inner flow guide holes of the upper partition plate and the outer flow guide holes of the upper partition plate in the radial direction of the upper partition plate are circular arch surfaces; and first two side walls of the flow guide holes of the lower baffle plate in the circumferential direction of the lower baffle plate, second two side walls of the inner flow guide holes of the upper partition plate and the outer flow guide holes of the upper partition plate in the circumferential direction of the upper partition plate are semi-cylindrical surfaces.
