Claim 3:
4. The compact L-shaped cylinder-cone combined tubular three-stage axial flow degassing device according to claim 1, wherein: the first-stage degasser performs the first-stage segmental vertical high speed swirling degassing operation, inner walls of the lower cylindrical degassing tube segment and the upper cylindrical degassing tube segment of the cylinder-cone degassing tube adopt a cylindrical surface, while an inner wall of the conical degassing tube segment adopts an inverted conical surface; and the first-stage gas collecting tube converges and transports the primary gas; the gas collecting hood is located in the tube cavity of the upper cylindrical degassing tube segment, and an inner surface and an outer surface of the shell of the gas collecting hood adopt conical surfaces of the same conicity; the gas collecting cylindrical tube segment adopts a long and thin straight tube, and a tube diameter and a wall thickness of the gas collecting cylindrical tube segment are both equal to those of the first-stage exhaust tube; the first-stage liquid discharge tube is located at the very bottom of the first-stage degasser, and converges and discharges the primary fluid, wherein a tube diameter of the upper liquid inlet tube segment and a tube diameter of the lower settling tube segment are both equal to that of the lower cylindrical degassing tube segment and are greater than that of the right liquid discharge straight tube segment, and the right liquid discharge straight tube segment is placed horizontally.
