Claim 7:
8. The three-stage tubular T-shaped degassing device with microbubble axial flow and spiral flow fields according to claim 1, wherein the spiral flow liquid inlet circular plate adopts a circular steel plate, and an arc-shaped liquid transportation slots realize communication between the arch-shaped liquid supply slots of the spiral flow cone pipe body and the axial flow drainage three-way pipe; cross-sections of the arch-shaped liquid transportation slots and the arc-shaped liquid supply slots are kept consistent in shape and size; and the spiral flow liquid inlet circular plate connects the spiral flow gas gathering pipe with the spiral flow exhaust pipe into an assembly through threaded connection;
the spiral flow drainage pipe adopts a vertical equal-diameter thick short pipe, and the spiral flow gas gathering pipe and the spiral flow exhaust pipe respectively adopt a vertical equal-diameter thin short pipe and a thin long pipe; and the spiral flow gas gathering pipe, the spiral flow exhaust pipe, the gas flow gathering pipe, and the gas flow transportation pipe are coaxially arranged in sequence from bottom to top, and have a same inner diameter; and
the spiral flow guiding cover of the spiral flow impeller adopts a center-closed conical shell and is configured to guide the spiral flow liquid that rotates at a high speed into each of the spiral flow blades which adopts a flat-plate blade, and is uniformly disposed around an outer ring surface of the spiral flow rod; an inner side of each of the spiral flow blades in a radial direction of the spiral flow rod is fixed to the spiral flow rod through circumferential welding, and an outer side of each of the spiral flow blades is fixed to an inner pipe wall of the spiral flow drainage pipe in an interference fit.
