Circle swirl vane and inner ring swirl vane can be adjusted the angle independently.
The further preferred embodiment of the present invention are as follows: the inner ring swirl vane can by it is independent adjust the angle so that its
Rotation direction is oppositely oriented with outer ring swirl vane.
The further preferred embodiment of the present invention are as follows: three circular holes are successively opened on the cross section of the swirl vane, often
Rib furcella rises there are six setting in a circular hole.
The further preferred embodiment of the present invention are as follows: the lug boss is cone cell or ellipticity.
Have the beneficial effect that the flue gas swirl-flow devices on desulfurizing tower of the invention, it is reasonable in design, it considers comprehensively de-
The characteristic of flue gas flow field in sulphur tower, and according to desulfurization effect and economy, the turbulent flow of flue gas swirl-flow devices can not only be optimized
Effect, and can better flue gas in uniform column, more reasonably optimize distributing tower internal resistance.Meanwhile mitigating because of section flue gas
The bad situation of desulfurization effect caused by amount is unevenly distributed, and reduce the power consumption of air-introduced machine.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Desulfurizing tower, including flue gas swirl-flow devices and gas inlet, nearly gas inlet end, separate gas inlet end and cigarette
Gas import middle-end is divided into three cigarette cyclonic flow regions, and flue gas swirl-flow devices, flue gas swirl-flow devices are disposed in three cigarette cyclonic flow regions
10 include flue gas swirling flow unit 11, it is preferable that is disposed with multiple flue gas swirling flow units 11, on flue gas swirl-flow devices 10 with enhancing
Flue gas mixing, improves flue gas eddy flow efficiency.
As shown in Figure 1 and Figure 4, the flue gas swirl-flow devices 10 on desulfurizing tower include multiple flue gases rotation that spiral board 1 is equipped with
