The specific embodiment
Desulfuration absorbing tower sprays suction apparatus with oxidation wind in the tower, as shown in Figure 1, it comprises slurries accelerating tube 1, slurries dilatation aspiration channel 2, aspiration channel sleeve pipe 3, oxidation air-slurries mixing tube 4 and oxidation air suction line 5, the conical pipe that slurries accelerating tube 1 diminishes from liquid feeding end to outlet end gradually for internal diameter, slurries dilatation aspiration channel 2 is provided with a plurality of air admission holes 21 for tube wall, internal diameter becomes large conical pipe gradually from liquid feeding end to outlet end, aspiration channel sleeve pipe 3 is that internal diameter is broad in the middle, pipe closes up at two ends small in ends, oxidation air-slurries mixing tube 4 is straight tube, aspiration channel sleeve pipe 3 is enclosed within slurries dilatation aspiration channel 2 outsides, the outlet end of slurries accelerating tube 1 axially is connected with an end of slurries dilatation aspiration channel 2 liquid feeding ends and aspiration channel sleeve pipe 3, be connected between slurries accelerating tube 1 and the slurries dilatation aspiration channel 2, the other end of aspiration channel sleeve pipe 3 is connected with the liquid feeding end of oxidation air-slurries mixing tube 4, has annular oxidation wind gap 31 between aspiration channel sleeve pipe 3 and the slurries dilatation aspiration channel 2, have annular air-breathing gap 32 between the inwall of the unsettled position that is connected in oxidation wind sleeve pipe 3 and with aspiration channel sleeve pipe 3 and oxidation air-slurries mixing tube 4 of the outlet end of slurries dilatation aspiration channel 2, an end of oxidation air suction line 5 laterally is connected with oxidation wind sleeve pipe 3, the other end extends to that desulfuration absorbing tower is outer to be connected to slurries with low-pressure oxidized blower fan or atmosphere oxidation air is provided.
