Description
Technical field
The invention belongs to environmental technology field, especially a kind of demister is with demister blade and high efficiency demister and answers
With.
Background technology
China is that coal production maximum in the world is national, and consumption of coal big country, needs substantial amounts of coal to use every year
In generating, atmosphere pollution brings serious influence to environment caused by coal.Wet Flue Gas Desulfurization Technology is coal-burning power plant
One of technology of most extensive dusty gas control used, but the flue gas in processed gas carries substantial amounts of slurry drop, because
This desulfurizer mist eliminator is that a most important equipment, traditional board-like demister can hardly be caught in whole wet desulfurization system
Grasp less droplet, especially in the case of flue gas flow at high speed, the big drop in flue gas can collide it is broken or
Established liquid film is torn by air-flow, so as to occur " the two sub-band water " of flue gas, reduces demisting efficiency.
China scientific and technical personnel have done some researchs in terms of demister reduces secondary droplets and reduces fouling, as patent discloses
Number (CN204469402) discloses a kind of combined defroster, is provided with spray pipeline in baffling board channel, is set on jet pipe
Hole is put, hole is sprayed water towards the turnover position in the passage, shower is set directly inside demister, such deflection plate
Inside can be washed into by shower, be not easy to form blocking, fouling in passage.Reduce demister by increasing flushing frequency
Fouling probability, water consumption is bigger, and the less drop that plate surface is formed is not easy quickly to flow down, so as to produce secondary droplets.Specially
Sharp publication number (CN201493005) discloses a kind of demister, and such a demister is divided into smart demisting and coarse defogging combining form, cigarette
Gas first passes through coarse defogging except the bigger drop of removal after entering demister, then smaller drop is removed by smart demisting, this
Kind of demister adds the resistance of system operation because be the combining form of demister, while also increase system investments into
This.
By contrast, the difference of the invention that essence with above-mentioned patent publication us be present.
The content of the invention
The defects of it is an object of the invention to overcome Conventional plate-type demister in the prior art, there is provided a kind of demister is with removing
Day with fog blade and high efficiency demister and application, the demister blade are transformed the blade construction of board-like demister, solved
The problem of secondary droplets of demister flue gas, the demisting efficiency of board-like demister is improved, system investment cost is low, the demister
It is can apply to demister blade in wet method fume desulfurizing system in the separation of flue gas and drop.
Technical scheme is used by the present invention solves above-mentioned technical problem：
A kind of demister demister blade, the demister blade include the blade that multiple parallel intervals are set, each
Blade includes blade body, network structure layer and cone, and the cone is disposed on blade body along blade body

Embodiment
Below in conjunction with the accompanying drawings and by embodiment, the present invention is further elaborated, and the following example is illustrative
, it is not limited, it is impossible to described limit protection scope of the present invention with following.
The structure be not described in detail in the present invention, annexation etc., it can be understood as ordinary skill in the art means.
A kind of demister demister blade, as shown in Figure 1, Figure 2 and Figure 3, the demister blade include multiple parallel
Spaced blade 4, for example, the spacing of each blade is 5~60mm, blade height is in 100~350mm, each leaf packet
Blade body 1, network structure layer 2 and cone 3 are included, the material of the cone is stainless steel and surface energy range is (1~3)
N/m, the cone are arranged at intervals (for example, welding) on the outer surface of blade body along blade body, the vertex of a cone of cone
Set towards the direction of drop gravitational settling, effect is the less droplet fast-growth of diameter is become the bigger drop of diameter
It is quick to fall down or is formed moisture film and quickly flow down, so as to realize efficient demisting, blade body outside the cone outside
Network structure layer is closely set on surface, and the outer surface of blade body sets network structure layer, can reduce air-flow to blade sheet
Body surface face is washed away, the specific area on and can increase blade body surface, contributes to the formation of moisture film to catch the less liquid of particle diameter
Drop and being capable of quick drainage；In order to not allow stickiness drop to be detained in wire side, mesh 5 can not be too small, the network structure layer material
Width of mesh scope for resistant material and surface is (1.5~2) times of liquid-drop diameter.
This demister blade is provided with cone and network structure layer, and the vertex of a cone of cone is towards the side of drop gravitational settling
To setting, effect is to make the less droplet fast-growth of diameter become the bigger drop of diameter quickly to fall down or formed water
Film quickly flows down, and so as to realize efficient demisting, network structure layer can reduce air-flow and blade body surface is washed away, and can
Increase the specific area on blade body surface, contribute to the formation of moisture film catch the less drop of particle diameter and can quick drainage,
Efficient demisting is further realized, the demister blade is transformed the blade construction of board-like demister, can be efficiently solved
The problem of secondary droplets of demister flue gas, the demisting efficiency of board-like demister is improved, efficient demisting, while its can be realized
Resistance is small, and system investment cost is low, and therefore, the demister can apply to cigarette in wet method fume desulfurizing system with demister blade
In the separation of gas and drop.
In the present embodiment, the blade body be shaped as zigzag, sinusoidal, abnormity or amendment in a zigzag.
In the present embodiment, the circular cone angular region of the vertex of a cone of the cone is 60 °~120 °, and circular cone bottom surface is a diameter of
2.5cm。
In the present embodiment, Teflon dope layer (not shown) is closely set on the outer surface of the blade body,
The cone is disposed on along blade body on the outer surface of Teflon dope layer, and the vertex of a cone of cone is towards drop gravity
The direction of sedimentation is set, close on the outer surface of the Teflon dope layer outside the cone to set network structure.
This demister blade is provided with Teflon dope layer, and Teflon long paint is the painting using polytetrafluoroethylene (PTFE) as body resin
Material, its advantage is high-low temperature resistant, and the temperature range used is -190 DEG C~250 DEG C, acid-alkali-corrosive-resisting, high lubrication, do not adhere to and
It is nontoxic, Teflon dope layer is closely set in blade body, and it can make the surface of blade body smooth, be not easy to adhere to
Dirty thing, reduce fouling probability.
A kind of high efficiency demister, it make use of above-mentioned demister demister blade.High efficiency demister is mainly by two parts
Composition, i.e. demister body and rinse-system, demister body include demister blade, fixture, fixture, support etc. according to certain
Conventional mode assemble, rinse-system can also use conventional rinse-system of the prior art, because
This no longer narration in detail.
From foregoing description, demister demister blade of the present invention goes for cigarette in wet method fume desulfurizing system
In the separation of gas and drop.
The operation principle of demister blade of the present invention is：
After flue gas enters in the demister blade path of demister, when channel direction is mutated, smoke movement direction can be sent out
Raw to change, because self inertia is bigger, the direction of motion will not change the drop that flue gas is mingled with, and be trapped by blade body, and meeting exists
Blade body surface forms liquid film, and the cone on blade body surface can make droplet quickly form big drop to flow down, netted
Structure sheaf reduces air-flow and liquid film is washed away, so as to realize efficient demisting.Further, the teflon material layer on surface effectively drops
Low fouling probability, so as to furthermore achieved that efficient demisting.
