Divide the resistance of gas mass transfer apparatus more than 300Pa or even 1000Pa easily with respect to other, the present apparatus substantially will not produce desulphurization system
Raw big energy consumption influences, and saves the energy such as water power.
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 can directly it be reflected from the increase on desulfuration efficiency.Desulfuration efficiency under equal conditions can be improved to 90%~95%.
4th, dehydration 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 level-one dehydration layer and two level dehydration layer.Since 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 in next bending part identical
Act on and be captured, and then add the chance that mist is captured, effectively increase demisting efficiency.The droplet being captured accumulates
Current, by the effect of gravity, under drop down onto in slurry pool, so as to fulfill 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 level-one and two level dehydration layer is 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, design is reasonable, and compact-sized, easy to operate, system resistance is small, and use reliability is high；Further, since each several part
Component is using the modular construction of convenient dismounting, so easy maintenance, operating cost is low.
