Flue Gas Desulphurization Tower Ridge Vane Pack Demister Self
Cleaning
Ridge type vane pack demister consists of two layers of vane packs and three layers of washing
water. The gas stream flow through the first and second vane packs
to eliminate the target-size mist. The standard module of the first
stage vane pack demister is with pitch of vane 30mm, and the
standard module of the second stage vane pack demister is with
pitch of vane 25mm. The vane plates are fixed by positioning rods
(both the upper part and the lower part are fixed). The positioning
rods and each chevron plate have corresponding round holes, which
are penetrated vertically with round rods, and the chevron plates
and positioning rods are penetrated into the fastener layer by
layer. Then it is welded with the blade to ensure that the
positioning rod and the round rod will not fall off, and at the
same time, the bearing capacity of the vane pack demister is
increased.
Technical characteristics of ridge vane pack demister:
Unique design, without dead angle of demisting in the whole tower,
triangle installation form, good stability, unique angle design.
Hook on the chevron plate is an option, to gain droplet collection
acceleration, and improve separation efficiency.
Technical Parameters of ridge type vane pack mist eliminator:
| Mist content at exit | ≤75 mg/Nm3 |
| Eliminated droplet size | ≥26 um |
| Pressure drop | ≤120 Pa |
| Flue gas velocity | 2.8 - 7.8 m/s (empty tower gas velocity) |

Flue gas desulphurization industry is becoming more and more
important as we pay more attention and effort to the environmental
protection all over the world. In Hualai we produce vane pack
demister mist eliminators for years, we are expecting to make more
contributions to this global action. Welcome your contact anytime!
