Description
Technical field
The utility model belongs to industrial smoke and administers field, is specially a kind of spray desulfurization technology.
Background technology
Flue gas desulfurization is control SO2Pollution and the effective way of acid rain.In the evolution of flue gas desulfurization technique, spray
It is the desulfuration reaction device used earliest to drench tower, and its advantage is can to form larger gas liquid interfacial area, simultaneity factor
Liquid-gas ratio can be smaller.In order to ensure good desulfurized effect, slurries, which spray, to form that size droplet diameter is smaller, then desulfuration efficiency is got over
It is high.The size droplet diameter that general spray column is produced is more than 1mm, and desulfuration efficiency is up to 95% or so.However, with new discharge
The appearance and implementation of standard, existing desulfurizer is difficult to meet country at this stage to be wanted to sulfur dioxide emissioning concentration limit value
Ask, in order to reach the requirement, while saving construction cost, the most economic way is to put forward effect to the progress of existing disengagement section to change
Make.
Utility model content
The problem of in order to solve that traditional spray column desulfuration efficiency is relatively low, be difficult to meet higher emissions standard, the utility model
There is provided the spray reaction tower after a kind of improvement, its technical scheme is as follows：
One kind spray reaction tower, is sequentially provided with slurry pool, gas access, spray reaction zone, demister gentle from top to bottom
Body is exported, it is characterised in that：
Multiple nozzles are provided with the spray reaction zone, the nozzle is connected by the circulatory system with the slurry pool, institute
Stating the circulatory system includes liquid line, the circulating pump on pipeline, microbubble generator and blower fan；
The water inlet of the circulating pump is connected with slurry pool outlet, and the microbubble generator is provided with air inlet, inlet
With bubble flow export, the gas outlet connection of its air inlet and blower fan, the delivery port connection of its inlet and circulating pump, the bubble
Flow export is connected with the nozzle.
The spray reaction zone is provided with multiple spraying layers, and each spraying layer of correspondence is furnished with least one microbubble generator.
Present invention spray reaction tower is additionally provided with more than one middle demister, and the middle demister is then arranged on adjacent
Between spraying layer.
Beneficial effect：
In existing technology, single fluid nozzle is made the liquid atomization using pressure, and the mist droplet particle size of generation is larger, if desired
Tiny droplet, then need to increase the pressure of pump.The utility model sets microbubble generator on the pipeline before spray section,
As gas-liquid mixed, air is dispersed into after micron-sized minute bubbles mix with slurries, enter back into nozzle, then flow through the liquid of nozzle
Body is changed into gas-liquid biphase fluid from single-phase flow, and the mist droplet particle size by the formation of nozzle rear slurry is small, because specific surface area further increases
Greatly, it is remarkably improved desulphurization reaction efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment 1；
Fig. 2 is the structural representation of embodiment 2；
Embodiment
In order to further elucidate the technical solution of the utility model and technical principle, below in conjunction with the accompanying drawings with specific embodiment
The utility model is described further.
Embodiment 1：
In the present embodiment by taking limestone/lime-gypsum method desulfurization as an example, a kind of spray reaction tower as shown in Figure 1, under
To being above sequentially provided with slurry pool 1, gas access 2, spray reaction zone 3, demister 4 and gas vent 5.
Multiple spraying layers are provided with the spray reaction zone 3, each spraying layer is made up of multiple atomizers again.The spray
Mouth is connected by the circulatory system with slurry pool 1.
The circulatory system includes being provided with circulation on the liquid line of connection nozzle and slurry pool 1, the liquid line
The each spraying layer of correspondence sets at least one microbubble generator 6 outside pump 8, the tower wall of the spray reaction zone 3.
The microbubble generator 6 is provided with air inlet 6-1, inlet 6-2 and bubble flow export 6-3（I.e. mixed liquor goes out
Mouthful）, the water inlet of the circulating pump 8 is exported with slurry pool 1 to be connected, and the air inlet 6-1 and oxidation fan 7 gas outlet connect
Connect, the inlet 6-2 is connected with the delivery port of circulating pump 8, the bubble flow export 6-3 is then connected with the nozzle.
It is lime stone slurry in slurry pool 1, microbubble generator liquid inlet 6-2 is delivered to by circulating pump 8, in micro- gas
Steep in generator 6, the air that slurries are conveyed with oxidation fan 7 is transported to spray reaction zone 3 after being sufficiently mixed, sprayed by being atomized
Smoke reaction of the sprinkling of mouth with entering desulfurizing tower from gas access 2.The gas-liquid biphase fluid of the formation of microbubble generator 6 is in nozzle
The smaller droplet of particle diameter is torn under effect, while improving the oxidation efficiency of absorption efficiency and slurries sulfite salt.
Embodiment 2：
On the basis of embodiment 1, the present embodiment is additionally provided with centre between first order spraying layer and second level spraying layer
Demister 9, the droplet amount of second level spraying layer is carried along into for reducing by air-flow.The middle demister 9, which is preferred to use, to be removed
Mist efficiency high, resistance be small and antisiludging demister, such as patent of Application No. 201510897113.0,201510900232.7
Demister disclosed in file.
Embodiment 3：
On the basis of embodiment 1 or embodiment 2, gas-liquid of the present embodiment microbubble generator 6 in its gas-liquid mixed chamber
The air-vent with corner structure, the sophisticated directional liquid flow direction of the corner structure are provided with interface（Such as Application No.
201610617272.5 patent document disclosed in micro bubble generation device shown in）.Roused in blower fan 7 into microbubble generator
When entering gas, on its gas-liquid interface, because the liquid of side quickly flows, the gas passed through from air-vent is in air-vent
The tip of corner structure is cut into micro-bubble, because the equivalent diameter of gas passage at the tip of corner structure becomes along liquid flow direction
To in infinitesimal, therefore the bubble produced has very small diameter, and dead time in the liquid phase significantly extends.Compared to using
In common microbubble demister, the present embodiment, the mass-transfer efficiency of gas-liquid has obtained more obvious raising.
The utility model spray reaction tower be easy to it is existing spray reaction tower on the basis of transformed, can with it is less into
The mark that carries of this completion spray column is transformed.
