Claim 7:
8. The compact L-shaped cylinder-cone combined tubular three-stage axial flow degassing device according to claim 1, wherein: the second-stage degasser performs the second-stage horizontal vane wheel swirling generating rapid axial flow degassing operation according to the axial flow vane wheel, the axial flow degassing tube adopts a two-end connected thick-walled cylindrical long tube, the axial flow vane wheel is located at a leftmost end of the axial flow degassing tube; an inner side surface of each swirling generating vane is fixed to an outer ring surface of the axial flow rod by means of circumferential welding, while outer side surfaces of all swirling generating vanes are located on the same cylindrical surface which is in interference fit with an inner wall of the axial flow degassing tube; a contour line of the swirling generating vane is a spiral line extending along the outer ring surface of the axial flow rod; a tangent line at the leftmost end point of the contour line of each swirling generating vane remains parallel to an axis of the axial flow rod, and the swirling generating vanes, in cooperation with the semi-ellipse spherical surface of the axial flow rod, can successively guide the gas-liquid uniform mixed flow to each swirling generating vane; a tangent line at the rightmost end point of the contour line of each swirling generating vane intersects with the axis of the axial flow rod at an acute angle, and the swirling generating vanes, in cooperation with the conical surface of the axial flow rod, can smoothly guide out a plurality of horizontal rapid gas-containing axial flows; a section area of the swirling generating vane gradually increases along the contour line thereof, and spiral axial flow vane grooves serve as flow channels of the gas-liquid uniform mixed flow and form a horizontal rapid axial flow field.
