The main atmosphere pollution in China belongs to typical coal-smoke pollution, maximum with the harm of dust and acid rain.Wherein, it makes
It is the sulfur dioxide (SO2) emissions in industrial smoke into the main reason for acid rain.Therefore the content of sulfur dioxide in stringent control flue gas,
Harm of the acid rain to environment is reduced, is an emphasis of green technology development.
Since currently used desulfurization technology is mainly wet desulfurizing process, mainly pass through desulfuration absorbing tower（Usually
Abbreviation desulfurizing tower）To realize.It is to spray slurries by spraying layer to wash the flue gas of uplink in desulfurizing tower common at present
It washs.Due to not only speed but also being unevenly distributed during gas uplink in desulfurizing tower so that flue gas connects with sprayed slurry
The tactile time is short, and the efficiency for carrying out gas-liquid exchange is affected, and influences desulfurization effect.In order to solve this problem, go out in the art
Showed a solution, lateral fairing added inside desulfurizing tower, make uplink flue gas pass through it is grid-like or netted
Fairing time-varying must be more evenly distributed, while reduce the rate of climb of flue gas.But this fairing can be largely
Ground consumes the kinetic energy of flow of flue gas, the resistance smaller for being subject to slurries downlink, and speed faster, is brought separately gas-liquid contact and exchange
The adverse effect of one side.
In conclusion design is a kind of not only can to make uplink smoke distribution evenly, but also flue gas gas-liquid can be made to exchange effect
Better fairing is those skilled in the art's problem to be solved.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
Turbulent flow intensifying device of the present invention, in application, being horizontally placed on the smoke air inlet of desulfurizing tower in desulfurizing tower
Between first layer spray equipment.When flue gas flows through the region, circulation area becomes smaller, and because of Venturi effect, flue gas flow rate carries
Height, the kinetic energy of flow of flue gas greatly increase, at a stalemate in the region one gas-liquid of formation with the slurries that top desulfurizing tower nozzle sprays
Section simultaneously causes strong gas-liquid turbulent flow to contact, and smashes drop, substantially increases the specific surface area of absorbent, changes tradition FGD
" liquid-in-gas " phenomenon in technology forms " gas-in-liquid " mass transfer effect, so as to the work for reaching the distribution of homogenizing gas-liquid, improving mass-transfer efficiency
With.
Turbulent flow intensifying device in the present embodiment is specific as shown in Figure 1, including multiple turbulent flow reinforced modules and connection turbulent flow
The stent of reinforced module.The stent outer rim is to meet the shape of desulfurization inner wall of tower, generally circular；Internal stent is in grid
Shape, each grid is for one turbulent flow reinforced module of setting；Internal stent grid is rectangle, is to adapt to outer rim at bracket edge
Shape and be provided with square or trapezoidal grid.
As shown in Figures 2 to 4, each turbulent flow reinforced module include the transverse tube layer of top, the longitudinal tubule (L tubule) layer of lower section, side company
Fishplate bar 1；
Wherein, the transverse tube layer includes upper and lower 2 groups turbulent flow sticks 2 parallel to each other, and every group of turbulent flow stick 2 is located at same level, on
One group of side, 2 cross section of turbulent flow stick is round, and the gap between adjacent turbulent flow stick is corresponding with one group of lower section, 2 position of turbulent flow stick, lower section
One group of 2 cross section of turbulent flow stick is rounded square；The longitudinal tubule (L tubule) layer includes the turbulent flow stick 2 that 1 group of section is rounded square.
The turbulent flow stick 2 is horizontally disposed PP hollow pipes, and both ends block, and the turbulent flow stick 2 of transverse tube layer and longitudinal tubule (L tubule) layer is mutual
It is perpendicular.
The turbulent flow stick 2 of the transverse tube layer and longitudinal tubule (L tubule) layer is connect by shaft 3 and sealed bearing with the connecting plate 1,
The central axes of the shaft 3 pass through 2 center of gravity of turbulent flow stick.The sealed bearing used in the present embodiment is band metallic sealed cover
Conventional model bearing.This setup so that when the air-flow for flowing through 2 both sides of turbulent flow stick is unbalanced, turbulent flow stick 2 can be
Air-flow drives lower rotation, gets rid of the slurries adhered on de- stick, mitigates fouling.The section of one group of turbulent flow stick 2 is circle above transverse tube layer,
It is because this group of turbulent flow stick and slurry liquid contacts are most, circle can reduce the contact area with slurries, mitigate fouling.
One group of transverse tube layer lower section and the cross section of longitudinal tubule (L tubule) layer turbulent flow stick 2 are rounded square, are not only easier quilt than circle
Air-flow drives rotation, and the air-flow that can flow through turbulent flow stick 2 when rotated changes, and goes out so as to influence turbulent flow intensifying device
Air-flow rule at mouthful strengthens mixed effect.When adjacent two turbulent flows stick 2 is opposite with diagonal, two turbulent flow stick 2 at this time
Between gap it is minimum, Venturi effect causes air velocity most fast；When adjacent two turbulent flows stick 2 is opposite with sideline direction, this
When two turbulent flow sticks 2 between gap it is maximum, air velocity is most slow；When the opposite sideline of adjacent two turbulent flows stick 2 is along gap center line pair
During title, air-flow is straight up；When the opposite sideline asymmetry of adjacent two turbulent flows stick 2, air-flow is amesiality.When cross section is circle
After the turbulent flow stick 2 of angle square drives rotation by air-flow, strong and weak, direction variation can occur for the air-flow group that the present invention is exported,
Turbulent flow effect has been superimposed except turbulence effects, has made gas-liquid mixed more abundant, clean-up effect is more preferable.
Through actually using result verification, turbulent flow intensifying device of the invention can reduce liquid-gas ratio（L/Q）Up to 40%；After installation
Desulfurizing tower, circulating load is reduced, so as to reduce the actual power consumption of circulating pump up to 40%；Desulfuration efficiency is up to more than 99%.
