Have the following advantages.
1st, spray coverage rate is big, stable.The present apparatus is used to be made up of spray supervisor, spray branch pipe, high efficiency nozzle
Network is sprayed, each layer of spray equipment separates angle and installed, and makes flue gas flow direction and droplet is full and uniform contacts, do not stay dead angle,
Coverage rate is up to 220%~300%, and separately angle installation also allows the stress of desulfuration absorbing tower body more to equalize to each layer, reaches
The effect of stable operation；Stability is three to five times of other absorpting forms.
2nd, low pressure drop, the saving energy.The present apparatus is calculated by theoretical calculation and many experiments, its resistance≤160Pa；
With respect to other point gas mass transfer apparatus more than 300Pa or even 1000Pa easily resistance, the present apparatus will not be produced to desulphurization system substantially
Raw big power consumption influence, saves water power equal energy source.
3rd, mass-transfer efficiency and desulfuration efficiency are high.The desulfurization absorbing liquid sprayed through spray equipment Multi-layer sprinkling layer is with entering
The flue gas constantly risen in tower is contacted, and is big → small → big venturi type change of latus rectum in local visual；From low flow velocity
It is changed into high flow rate, breaks up thin liquid layer, form countless fine mists, greatly increase the surface area of gas-liquid contact, improves mass-transfer efficiency,
And directly can be reflected from the increase on desulfuration efficiency.Desulfuration efficiency under equal conditions can be improved to 90%~95%.
4th, dewatering efficiency is high.The desulfurization absorbing liquid sprayed through spray equipment, with the flue gas after desulfurization, with certain speed
Degree passes sequentially through and is folded to dewatering blade more on dehydration device one-level dehydration layer and two grades of dehydration layers.Because flue gas is by quickly, even
Change the direction of motion continuously, therefore because of the effect of centrifugal force and inertia, the droplet in flue gas strike dehydration device be folded to it is de-
In wiper blade and then it is captured down；In a upper bending part, the drop not being removed, pass through identical in next bending part
Act on and be captured, and then add the chance that mist is captured, effectively increase demisting efficiency.The droplet being captured is accumulated
Current, by the effect of gravity, under drop down onto in slurry pool, so as to realize the separation of gas-liquid, the flue gas for flowing through dehydration device reaches
Discharged after to demisting requirement.After gas is by dehydration device, substantially free of mist；Dehydration effect under equal conditions can be improved
Rate 40%~50%.
5th, dehydration device is less scaling and blocks.The backwash spray head set on each backwash layer backwash water pipe, energy
Enough when the upper and lower both sides pressure difference of dehydration device is bigger than normal, layer is dehydrated to one-level and two grades of dehydration layers are rinsed, so that layer will be dehydrated
The black dirt of upper deposition is rinsed well, and ensures that dehydration device outlet droplet content meets discharge standard.
6th, reasonable in design, compact conformation is easy to operate, and SR is small, high using reliability；Further, since each several part
Component is using the modular construction of convenient dismounting, so easy maintenance, operating cost is low.

The spray supervisor 12 of the spraying layer 8 of spraying layer 7 and the 3rd；Afterwards, spray liquid is by being arranged on spray supervisor 12 and each spray branch pipe
High efficiency nozzle 14 on 13, netted spray system is formed in each spraying layer.The cigarette entered from smoke inlet 2 in absorption tower main body 1
Gas, at the uniform velocity rises in tower, is contacted by the efficient mixing with each spraying layer drop, forms good gas-liquid contact reaction circle
Face, so as to remove the SO in flue gas2Deng sour gas.
Then, the desulfurization absorbing liquid sprayed through spray equipment 3, passes through with the flue gas after desulfurization, with certain speed
The one-level dehydration passage 40 of the one-level of dehydration device 4 dehydration layer 25；Because flue gas is in one-level dehydration passage 40, by rapidly, continuously
Ground changes the direction of motion, therefore because of the effect of centrifugal force and inertia, bulky grain droplet strikes many of one-level dehydration layer 25 in flue gas
It is folded on one-level dewatering blade 39 and then is captured down.Afterwards, the little particle mist for being dehydrated in layer 25, not being removed in one-level
Drop continues to rise, by two grades of dehydration passages 46 of two grades of dehydration layers 28；Due to two grades of dehydration passages 46 of two grades of dehydration layers 28
With double-bending structure and spacing is smaller, in favor of the trapping to little particle droplet, effectively improve demisting efficiency.
After one-level dehydration layer 25 and two grades of dehydration layers 28 by dehydration device 4, in flue gas most of drop all can by except
Fall, only few partial drop may proceed to be discharged into air through outlet flue 5 with flue gas, and this partial drop also complies with existing industry row
Put standard.Also, in the running of novel absorbent complexes, according to specifically used needs, dehydration device 4 is used to rinse
The one-level bottom backwash layer 24 of the downside of one-level dehydration layer 25, can be at interval of the continuous flushing for carrying out 1 minute for 30 minutes；For rushing
The one-level top backwash layer 26 of the upside of one-level dehydration layer 25 is washed, can be at interval of the continuous flushing for carrying out 1 minute for 60 minutes.For
Two grades of bottoms backwash layer 27 of two grades of downsides of dehydration layer 28 is rinsed, can be at interval of the continuous flushing for carrying out 1 minute for 90 minutes；And
Two grades of tops for rinsing two grades of upsides of dehydration layer 28 backwash layer 29, can combine inspection situation and carry out manual flushing.With
When the upper and lower both sides pressure difference of dehydration device 4 is bigger than normal, layer 25 is dehydrated to one-level and two grades of dehydration layers 28 are rinsed, each layer is taken off
The black dirt deposited on water layer is rinsed well, prevents from being dehydrated the generation of layer clogging, the use reliability of lifting device.
