Claim 8:
9. The compact L-shaped cylinder-cone combined tubular three-stage axial flow degassing device according to claim 1, wherein: each axial flow vane of the vane rectifier adopts a trapezoid plate structure and is located at the rightmost end of the axial flow degassing tube cavity, all axial flow vanes are located on the same cylindrical surface along a radially outer side surface of the second-stage gas collecting tube, and the cylindrical surface on which the outer side surface of each axial flow vane is located and an inner wall of the axial flow degassing tube are in interference fit; and the second-stage gas collecting tube converges and discharges the secondary gas; the gas collecting bent tube adopts a long and thin bent tube, and a horizontal segment thereof and the axial flow degassing tube are coaxially arranged and the vertical segment thereof and a liquid collecting tube are coaxially arranged; the gas collecting thin conical tube adopts a tube shell, an inner tube wall and an outer tube wall of which are both conical surfaces, and controls a liquid-containing content of gas inside of the second-stage gas collecting tube; the gas collecting thick conical tube can successively guide the secondary fluid into the vane rectifier; the second-stage liquid discharge tube is provided with flanges at all ends of its T-shaped tube segment, and is located at the rightmost side of the second-stage degasser; the second-stage liquid discharge tube converges and discharges the secondary fluid; an inner tube wall and an outer tube wall of the right reduced liquid discharge tube segment both adopt a conical surface, and the upper liquid discharge straight tube segment is vertically placed.
