Description
Technical field
This utility model relates to desulfurizing tower flue gas flow equalizing technical field, is specifically related to a kind of equal with flue gas
The desulfurizing tower of stream pallet.
Background technology
Along with global environment deterioration, water scarcity, country advocates all kinds of enterprise and reduces pollution, saves
With water, as the power industry of power consumption use water rich and influential family, the most deeply excavate existing power station unit reduction of discharging,
Water saving potential, becomes the major issue of each enterprise common concern.
Along with the environmental regulation of country is the most perfect, the whole supporting flue gas desulfurization of active service coal unit
Device.In common wet desulfurization system, flue gas enters from the bottom of desulfurizing tower, and reaction liquid leads to
Crossing circulating pump to get to the top of desulfurizing tower and spray from specific injection apparatus, then flue gas is to upstream
Dynamic, reaction liquid moves downward with atomised form, thus occurs chemistry to send out in desulfurizing tower and should remove cigarette
SO in gasX.But owing to the uneven meeting of flowing of flue gas causes being decreased obviously of desulfuration efficiency.With
Time, owing to flue gas has higher speed, and the contact area of flue gas and reactant liquor is relatively big, causes cigarette
The rolling action of gas is obvious.The advantage of limestone-plaster wet desulfurizing system is a lot, but is running
During some problems the most often occur.Limestone Gypsum Fibrosum is used in some power plant not installing GGH
During wet method fume desulfurizing system, often due to flue gas carries serosity causes asking of " gypsum rain "
Topic." gypsum rain " refers to that flue gas carries serosity and gets rid of from chimney, due to the relatively low diffusion energy of flue-gas temperature
Power is more weak, and flue gas cannot obtain enough liftings, and the dress liquid in flue gas assembles sedimentation, near cigarette meat
Fall earthward.Owing to serosity containing the acidic materials such as sulfur dioxide, sulfur trioxide Gypsum Fibrosum, can be to week
The environment enclosed damages." gypsum rain " problem is limestone-plaster wet desulfurizing system safety
The maximum hidden danger of stable operation.
The flow of flue gas of entrance desulfurizing tower is uneven is to affect smoke desulfurization efficiency and desulfurizer mist eliminator
The key factor of demisting efficiency.In order to allow the flue gas that enters in desulfurizing tower can Uniform Flow, now than
Relatively widespread practice is to allow flue gas enter desulfurizing tower with the downward angle of attack, then adds one on import
Being uniformly distributed the pallet of the identical aperture in multiple aperture, compared to being not added with pallet, this pallet can allow flue gas
Flowing more uniform.But at this after uniform pallet, flue gas remains away from gas approach
End flow is big, flow velocity fast, and one end flow near gas approach is little, flow velocity is slow.So can cause cigarette
The imperfect flow of gas, desulfuration efficiency and demisting efficiency decline.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, the purpose of this utility model is to provide one
With the desulfurizing tower of flue gas flow equalizing pallet, the flue gas come in from desulfurizing tower entrance encounters slurry then up
Motion, can cause that the flow away from gas approach end is big, flow velocity fast in the process, and near import
The flow of end is little, flow velocity is slow；Current-sharing pallet in this utility model can effectively increase away from import
The resistance of end, reduces the resistance near entrance point so that the flowing in whole region is more uniform, thus
Reach preferable desulfurization, except fog effect.
In order to realize above-mentioned utility model purpose, this utility model adopts the technical scheme that:
A kind of desulfurizing tower with flue gas flow equalizing pallet, including be arranged on desulfurizing tower gas approach 1 it
On current-sharing pallet 8, the aperture of described current-sharing pallet 8 is from entering to away from flue gas near gas approach side
Mouth side changes from big to small.This construction features can ensure flue gas by time have certain equal
Stream effect, thus after pallet, produce more uniform flow field.
The implementation of above-mentioned desulfurizing tower flue gas flow equalizing pallet is: be fitted without in original desulfurizing tower
Pallet, then install the current-sharing pallet in this programme on gas approach；As original desulfurizing tower is installed
There is the uniform pallet that aperture is identical, then the current-sharing pallet of the aperture gradual change being replaced with in this programme.
Enter the flue gas in desulfurizing tower and flow more uniform after the non-homogeneous pallet in the program, thus reach
To more preferable desulfurization with except fog effect.
Compared to the prior art this utility model, has the advantage that
This programme is simple to operate, and enforceability is strong, changes less to original system, only need to install this equal
Flow pallet or original pallet is replaced.This device is so that the flue gas that enters in desulfurizing tower
Flowing is more uniform, thus is fully contacted reaction with desulfurization slurry, uniformly through demister, reaches more
Good desulfurization and except fog effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is this utility model non-homogeneous current-sharing pallet.
In figure: 1 is gas approach, 2 is serosity pond, and 3 is slurry circulating pump, and 4 is flusher,
5 is filler, and 6 is demister, and 7 is exhanst gas outlet, and 8 is current-sharing pallet.
Detailed description of the invention
Below in conjunction with accompanying drawing and be embodied as case, this utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of desulfurizing tower with flue gas flow equalizing pallet of this utility model, bag
Including the current-sharing pallet 8 being arranged on the gas approach 1 of desulfurizing tower, this current-sharing pallet 8 has close
Gas approach lateral aperture is relatively big, the feature being gradually reduced away from gas approach aperture.From desulfurizing tower entrance
The flue gas come in is encountered slurry and is moved then up, can cause away from gas approach end in the process
Flow is big, flow velocity is fast, and the flow of close entrance point is little, flow velocity is slow.Current-sharing in this utility model
Pallet can effectively increase the resistance away from entrance point, reduces the resistance near entrance point so that whole
The flowing in individual region is more uniform, thus reaches preferable desulfurization, except fog effect.
The implementation of this utility model desulfurizing tower flue gas flow equalizing pallet is: do not have in original desulfurizing tower
Pallet is installed, then the current-sharing pallet in this programme is installed on gas approach；In original desulfurizing tower
The uniform pallet that aperture is identical is installed, then the current-sharing torr of the aperture gradual change being replaced with in this programme
Dish.Enter the flue gas in desulfurizing tower and flow more uniform after the non-homogeneous pallet in the program, from
And reach more preferable desulfurization and except fog effect.
This programme is simple to operate, and enforceability is strong, changes less to original system, only need to install this equal
Stream pallet or original pallet is replaced, but after installing so that whole system take off
Sulfur and except fog effect more preferable.
