Claim 3:
4. The three-stage tubular T-shaped degassing device with microbubble axial flow and spiral flow fields according to claim 1, wherein the swirling pipe body of the microbubble cyclone adopts a horizontal equal-diameter short pipe; the ellipsoidal flow leading body of the swirling imitated cone body is configured with a hemi-ellipsoidal surface, and is configured to smoothly lead the microbubble uniform mixed axial flow to spiral gear slots; the columnar gear body is configured with a cylindrical surface and is uniformly welded with the microbubble spiral gears in a circumferential direction of the columnar gear body; and the conical flow guiding body is configured with a conical surface and is configured to smoothly guide the multiple strands of rotational axial flows to the lumen of the axial flow column pipe body; and
tooth traces of the microbubble spiral teeth in the microbubble spiral gear are spiral lines spread along a cylindrical surface where the columnar gear body is located, and screw pitches of spiral lines where the tooth traces of the microbubble spiral teeth are located, gradually increase along an axial direction of the swirling imitated cone body; cross-sections of the microbubble spiral teeth perpendicular to the tooth traces of the microbubble spiral teeth is trapezoid; tangent lines at start points of the tooth traces of the microbubble spiral teeth is parallel to an axial line of the swirling imitated cone body, and tangent lines at end points of the tooth traces are obliquely interlaced with the axial line of the swirling imitated cone body; outer tooth surfaces of the microbubble spiral gears in a radial direction of the swirling imitated cone body are configured as a cylindrical surfaces, and a cylindrical surface where the outer tooth surfaces of the microbubble spiral gears are located is in an interference fit with an inner pipe wall of the swirling pipe body; the spiral gear slots between the microbubble spiral teeth are configured as runners for speeding up and changing a direction of the microbubble uniform mixed axial flow; and areas of cross-sections of the spiral gear slots perpendicular to the tooth traces of the microbubble spiral teeth continuously decrease in the axial direction of the swirling imitated cone body.
