The specific embodiment
A kind of hypergravity flue-gas dust-removing and desulfurization all-in-one, it is characterized in that: this machine comprises: frame 2, housing 4, the ventilative cylinder 5 that is arranged on housing 4 inner chambers and ventilative cylinder 5 motor rotating 10 of driving; Described frame 2 is the steel construction rectangular frame, and the upper vertical of frame 2 is fixed two side plates 3; Described housing 4 is a special pipe, and the housing two ends are fixed between two side plates 3; One side on housing 4 tops is connected with Venturi tube 66 1 ends by ring flange 9; The other end of described Venturi tube 6 is connected with the smokejack of boiler by appendix; The bottom of housing 4 makes discharge outlet 4-1, in the sedimentation basin 1 outside the described discharge outlet 4-1 insertion machine; The top of housing 4 is provided with blast pipe 13, and described blast pipe 13 is connected with machine air-introduced machine outward; Described ventilative cylinder 5 is arranged on the inner chamber of housing 4, and the armature spindle 5-1 two ends of ventilative cylinder 5 are connected with side plate 3, blast pipe 13 respectively by bearing block 14; Armature spindle 5-1 one end is connected with motor 10 on being installed in frame 2 by band transmission 11.
