Layer, 8- demisters.
Fig. 2 and Fig. 3 is the detail of construction for the efficient current equalizer that the utility model is suitable for desulfuration spray tower.
Embodiment
As shown in Figure 1, the utility model is efficiently flowed including desulfurizing tower 1, desulfurizing tower entrance 2, desulfurizing tower outlet 3, level-one
The efficient current equalizer 5 of device 4, two level, circulating pump 6, spraying layer 7, demister 8, the bottom of the desulfurizing tower 1 set desulfurizing tower to enter
Mouth 2, desulfurizing tower top set desulfurizing tower to export 3, and the efficient current equalizer 4 of level-one is located at desulfurizing tower gas approach opposite side, occupies
1/2 tower diameter；The efficient current equalizer 5 of two level is located at desulfurizing tower gas approach side, occupies 3/5 tower diameter；Desulfurizing tower is externally provided with circulating pump
6, and every circulating pump corresponds to one layer of spraying layer, 7 top nozzle of spraying layer is evenly arranged, no spray dead angle；It is equipped with above spraying layer
Demister, the drop that removing flue gas carries.
As shown in Figure 1, the efficient current equalizer of level-one, two level interlaced arrangement at 1 diverse location of desulfurizing tower, different height,
The whirlpool of different scale in desulfurizing tower can be effectively destroyed, improves flow field uniformity.The percent opening of the efficient current equalizer of level-one will
Higher than the efficient current equalizer of two level, flue gas can be effectively prevented to pass through from the efficient current equalizer gap of two-stage, and two-stage is efficiently equal
The difference in height for flowing device is no more than 1 meter.
As shown in Figures 2 and 3, efficient current equalizer is two-way cross perforate column plate, and column plate subtended angle a is 20 ° ~ 60 °, is reduced
The upward initial velocity of drop, reduces liquid foam entrainment amount, to adapt to different treatment quantities, can increase gas-liquid mass transfer interface；
Two-way cross perforate, accelerates the mixing of flue gas, improves the uniformity of flue gas.
The idiographic flow of the device：Flue gas is after desulfurizing tower entrance 2 enters desulfurizing tower 1, and space drastically expands, and flue gas is in
Reorganize in flow process, its velocity flow profile is extremely uneven, and forms the whirlpool of different scale.Then 1/2 tower of level-one is passed through
The current equalizer 5 of 3/5 tower diameter of current equalizer 4 and two level in footpath, current equalizer are two-way cross perforate column plate, and column plate has certain
Angle of inclination, can effectively destroy the whirlpool of different scale above slurry pool, and flue gas uniformity can be improved, reduce liquid foam folder
Ribbon amount, while every grade of current equalizer is respectively formed on certain thickness liquid film, enhances gas-liquid mass transfer, improves desulfuration efficiency.So
Continue mass transfer with sprayed slurry counter current contacting again afterwards and absorb, improve desulfuration efficiency.Then again by the demister above spraying layer
8, the drop that removing flue gas carries, is discharged to desulfurizing tower outlet 3.
The above, only explains the better embodiment of the utility model, is not intended to according to this make the utility model
Limitation in any form, so every any modification or change under the creation spirit of the utility model, made, all should
Belong to the scope that the utility model is intended to protection.
