Claim 9:
10. The compact L-shaped cylinder-cone combined tubular three-stage axial flow degassing device according to claim 1, wherein: the third-stage degasser performs the third-stage vertical reversing deep degassing operation according to the wet gas reversing tube, the wet gas transportation tube segment of the wet gas reversing tube is vertically placed, and is in coaxial and layered arrangement with the liquid collecting tube from the inside out; a double-tube buffer ring cavity realizes buffering and pressure stabilization of the tertiary fluid, the reversing tube segment vertically intersects with the liquid collecting tube, the secondary gas transported by the wet gas transportation tube segment is reversed and slowed down by the reversing conical cavity of the reversing tube segment, and then is shot into the double-tube buffer ring cavity and realizes deep degassing; a sum of a flow pressure of the tertiary gas in the third-stage exhaust tube and a liquid column differential pressure of the liquid collecting tube maintains dynamic equilibrium with a pressure of the tertiary fluid inside of the third-stage liquid discharge tube; and the liquid collecting tube adopts a two-end communication thin-walled cylindrical tube, and the third-stage liquid discharge tube adopts a long and thin straight tube; an inner wall of the third-stage exhaust tube adopts a conical surface, and discharges the tertiary gas; the disc connecting sleeve adopts a disc tube socket flange, wherein the socket flange realizes axial positioning of the disc connecting sleeve, an outer ring surface of the connecting sleeve and the tube wall of the liquid discharge straight tube segment on the second-stage liquid discharge tube are in clearance fit, and an upper part of the inner wall of the connecting sleeve and a lower part of an outer ring surface of the wet gas transportation tube segment are in interference fit.
