Tube bank inner barrel is stated, the wash tub pipe is also connect with external water source, the pipeline between the wash tub pipe and external water source
On be provided with check valve, be provided with several groups flooding nozzle on the wash tub pipe, every group of flooding nozzle includes two rows of rinsing spray
Mouth, two rows of flooding nozzles are separately positioned on above and below the cyclone；The main function for rinsing water system is cleaning pipe
The solids such as beam internal cyclones, accelerator, tube bank inner cylinder, the gypsum, the dust that adhere on the double-deck rectifying tube grid, prevent tube bank from tying
Dirt blocking.
Further, the tube bank channel controller includes control sphere, supporting element, compressed air hose, the control
Sphere is erected at the tube bank cylinder top by support frame, and the control ball interior is connected to compressed air hose, the pressure
Contracting air hose is connected to compressed gas source；When the compressed air hose by being connected with control ball interior injects in control sphere
Compressed air, the expansion after full of air of control sphere can cut off tube bank flow area, prevent flue gas from tube bank inside stream
It crosses；And emptied when the compressed air in control sphere, the flow area that control sphere is restrained after losing heart restores unimpeded again；When
Control sphere when practical exhaust gas volumn reaches design exhaust gas volumn in desulfurizing tower, in all tube banks of self-adapting type high-effective dust-removing demister
All in air deflating state, i.e., all tube bank channels are all to open, and tube bank can all participate in work.And when practical in desulfurizing tower
When exhaust gas volumn is significantly less than design exhaust gas volumn, since bundled tube dedusting demister is to be separated using centrifugal force except taking in flue gas
The flue dust and droplet of band, thus when restrain inside smoke flow velocity reduce after its generate centrifugal force also reduce therewith, flue dust and
Droplet separating capacity also decreases, in order to guarantee that bundled tube dedusting demister equally has dedusting well after exhaust gas volumn decline
Defogging effect can only make a portion tube bank efficient by tube bank channel controller come flexible control bundle working quantity
It is negative to efficiently solve the low flue gas of bundled tube dedusting demister to realize that tube bank working flow rate is always at optimum range for work
The problem of lotus bad adaptability.
The utility model has the advantages that compared with the existing technology
The utility model tube bank inside smoke flow field is more uniform, flue gas load better adaptability, less scaling blocking, shape
At centrifugal force it is bigger, have higher removal ability to fine solid particle and droplet, can be relatively reliable and steadily realize that flue dust is super
Low emission.
