Claim 6:
7. The three-stage tubular T-shaped degassing device with microbubble axial flow and spiral flow fields according to claim 1, wherein the conical spiral flow degasser implements the vertical degassing operation; the spiral flow cone pipe body adopts a vertical variable-diameter thick-wall thick pipe; the arch-shaped liquid supply slots are uniformly distributed in a circumferential direction of the spiral flow cone pipe body; an inner slot surface and an outer slot surface of each arch-shaped liquid supply slot in a radial direction of the spiral flow cone pipe body adopt circular arch surfaces with different diameters, and slot surfaces at two sides of the arch-shaped liquid supply slot in a circumferential direction of the spiral flow cone pipe body adopt semi-cylindrical surfaces; a diameter of the circular arch surface, where the outer slot surface of the arch-shaped liquid supply slot in the radial direction of the spiral flow cone pipe body is located, is equal to an inner diameter of the axial flow upper vertical drainage pipe, an inner diameter of the axial flow lower vertical drainage pipe, and an inner diameter of the reversing buffer column pipe body; and
axial heights of the spiral runner, the conical spiral flow runner and the columnar spiral flow runner in the spiral flow cone pipe body decrease in sequence; a center line connecting center points of all cross-sections of the spiral runner adopts a variable-pitch spiral line; the cross-sections of the spiral runner perpendicular to the center line are semicircular surfaces, and areas of circular surfaces where the cross-sections perpendicular to the center line of the spiral runner are located, gradually increase from top to bottom, and distances from the center points of the circular surfaces where the cross-sections are located to an axis of the spiral flow cone pipe body continuously decreases from top to bottom; a runner located at a top end of the spiral runner is kept communication with the arch-shaped liquid supply slots; and a diameter of a second small end circular surface of a conical surface where the pipeline wall of the conical spiral flow runner is located is equal to a diameter of a cylindrical surface where the pipeline wall of the columnar spiral flow runner is located.
