According to the technical scheme that the utility model provides, rotational flow aeration device comprises Y-tube and aeration tube, it is characterized in that: aeration tube bottom centre is provided with gas inlet, and gas inlet is connected with the outlet side of Y-tube; Siphunculus is fixed on column upper end, the affixed support baseboard of column lower end; Aeration tube inner bottom part is provided with several straight half vanes, and aeration tube inner bottom part center is provided with diversion column, and in aeration tube, middle part is provided with multiple first bubble cutting ailhead along body inner side-wall, and aeration tube internal upper part is provided with multiple second bubble cutting ailhead along body inner side-wall.
Further, multiple first bubble cutting ailhead is uniformly distributed along the body inner side-wall circumferential direction of aeration tube.
Further, multiple second bubble cutting ailhead is uniformly distributed along the body inner side-wall circumferential direction of aeration tube.
Further, the diameter of the second bubble cutting ailhead is greater than the diameter of first bubble cutting ailhead.
Further, stiffening web is provided with between the body of the both sides, outlet side of Y-tube and aeration tube sidewall.
Further, the inlet end joint flange end face of Y-tube side.
Compared with the prior art the utility model has the following advantages:
The utility model structure is simple, compact, reasonable, through the segmentation layer by layer of straight half vane, first bubble cutting ailhead, the second bubble cutting ailhead, bubble is cut into small bubbles, and fully mix with the mud mixture of surrounding, add rate of mass transfer and the coefficient of oxygen utilization of oxygen, possess higher aeration efficiency; Its stable and reliable operation, blocking is less likely to occur, long service life.
