Claim 4:
5. The compact L-shaped cylinder-cone combined tubular three-stage axial flow degassing device according to claim 1, wherein: the swirling stopping cone of the swirling stopping rectifier is located at a lower part in a tube cavity of the lower cylindrical degassing tube segment; an inner surface and an outer surface of the shell of the swirling stopping cone adopt conical surfaces of the same conicity, and the rectifying rod adopts a round rod and is provided with a cone at a bottom; the rectifying vanes adopt a plate structure and are located in the tube cavity of the upper liquid inlet tube segment, a top end surface and a bottom end surface of each rectifying vane, as well as a top end surface of its guide groove all form a conical surface along the circumferential direction; a conicity of the conical surface on which the shell of the swirling stopping cone is located is equal to that of the conical surface on which the top end surface, the bottom end surface, as well as the top end surface of the guide groove of each rectifying vane is located, and is larger than that of a conical surface on which a shell of a gas collecting hood is located; the rectifying vanes are all located on the same cylindrical surface along a radially outer side surface of the rectifying rod, and the cylindrical surface on which the outer side surface of each rectifying vane and an inner wall of the upper liquid inlet tube segment are in interference fit.
