Claim 4:
5. The separation device with two-stage gas-liquid mixture and conical spiral fields according to claim 3, wherein axial lengths of the outer micropore ceramic pipe, the middle micropore ceramic pipe and the inner micropore ceramic pipe of the first-stage uniform mixer are equal; a cylindrical pipe cavity of the inner micropore ceramic pipe is communicated with the liquid inlet buffer pipe through the flow guide round hole in the lower baffle plate; an annular cavity between the middle micropore ceramic pipe and the inner micropore ceramic pipe is communicated with the second-stage mixing pipe through the inner flow guide holes of the upper partition plate; an annular cavity between the outer micropore ceramic pipe and the middle micropore ceramic pipe is communicated with the liquid inlet buffer pipe through the flow guide holes of the lower baffle plate; an annular cavity between the first-stage mixing pipe and the outer micropore ceramic pipe is communicated with the second-stage mixing pipe through the outer flow guide holes of the upper partition plate; a taper of a conical surface of a hole wall of the large-cone micropore channel is larger than a taper of a conical surface of a hole wall of the small-cone micropore channel; a cone height of the conical surface of the hole wall of the large-cone micropore channel, an axial length of a cylindrical surface of a hole wall of the cylindrical micropore channel, and a cone height of the conical surface of the hole wall of the small-cone micropore channel are gradually increased; the small-cone micropore channel of the outer micropore ceramic pipe is arranged on an inner side of the outer micropore ceramic pipe along a radial direction of the outer micropore ceramic pipe, and the small-cone micropore channel of the inner micropore ceramic pipe is arranged on an inner side of the inner micropore ceramic pipe along a radial direction of the inner micropore ceramic pipe; the small-cone micropore channel of the middle micropore ceramic pipe is arranged on an outer side thereof along a radial direction of the middle micropore ceramic pipe; the annular clamping rings of the outer micropore ceramic pipe are matched with the outer one of the annular clamping grooves of the upper partition plate in the radial direction of the upper partition plate and the outer one of the annular clamping grooves of the lower baffle plate in the radial direction of the lower baffle plate; the annular clamping hoops of the middle micropore ceramic pipe are matched with the middle one of the annular clamping grooves of the upper partition plate in the radial direction of the upper partition plate and the middle one of the annular clamping grooves of the lower baffle plate in the radial direction of the lower baffle plate; the annular clamping rings of the inner micropore ceramic pipe are matched with the inner one of the annular clamping grooves of the upper partition plate in the radial direction of the upper partition plate and the inner one of the annular clamping grooves of the lower baffle plate in the radial direction of the lower baffle plate, such that axial fixation and up-and-down bidirectional limitation of the outer micropore porcelain pipe, the middle micropore porcelain pipe and the inner micropore porcelain pipe are enabled.
