Claim 2:
3. The compact L-shaped cylinder-cone combined tubular three-stage axial flow degassing device according to claim 1, wherein: two ends of the swirling generating tube of the cylindrical tube swirling generator are respectively provided with double flanges and a single flange, and a central part of a topmost flange is drilled with a socket hole; a tooth trace of the reduced swirling generating teeth is a spiral line, which is placed right-handed and has an increasing pitch of the spiral line from top to bottom, a section of the reduced swirling generating teeth takes a shape of an isosceles triangle; the gas-containing fluid inside of the vertical high speed swirling field continuously rotates and speeds up, and is adjusted to be a vertical high speed gas-containing swirling; a tube wall of the swirling generating tube located at an upper entrance of the reduced spiral tooth slot is drilled with a swirling generating liquid inlet hole, wherein the swirling generating liquid inlet hole is obliquely placed, and an angle between its central line and the horizontal plane is equal to a lead angle of the spiral line on which the upper tooth trace of the reduced swirling generating teeth is located; one end of the spiral liquid inlet tube is provided with a flange and the other end is provided with a wedge-shaped groove, and a part where the wedge-shaped groove of the spiral liquid inlet tube intersects with an inner wall of the swirling generating tube maintains tangent with slot bottom surface of the reduced spiral tooth slot; the first-stage exhaust tube adopts a long and thin bent tube, wherein one end of the first-stage exhaust tube and a first-stage gas collecting tube are coaxially arranged; the tube connecting sleeve adopts a thick-walled tube, wherein the tube connecting sleeve and the swirling generating tube are coaxially arranged.
