Description
Technical field
The utility model is related to a kind of demister, more particularly to a kind of Convenient descaling demister.
Background technology
Ridge type demister is made up of two layers of herringbone demister and three layers of flushing water, and first order demister is thick demisting,
Second level demister is smart demisting, and first order demister standard module is made up of 22 blades, second level demister standard module
It is made up of, is fixed by the locating rod upper and lower part that is fixed between blade 24 blades, locating rod and per a piece of blade
On have corresponding circular hole, vertically penetrated with FRPP poles, blade and positioning rod member penetrate fastening layer by layer, then again with blade weldering
Be connected to together, it is ensured that locating rod and pole will not fall off, at the same also increase demister bearing capacity, ridge-roof type demister it is excellent
Point is the mean flow rate that flue gas is less than horizontal cross-section in tower by the flow velocity of blade normal, so, even if flue gas flow rate in tower
It is higher, when by demister, because circulation area increases and make it that flue gas flow rate reduces, still, due to ridge-roof type demister
Need to reserve rectangular channel on the section on absorption tower, and absorption tower is circular, so area needs to be closed with blind plate
Come,, can be with addition, the more plate demister of the structure of ridge-roof type demister is more stable so that a part of advantage of partial offset
The temperature of tolerance is higher, therefore, when desulphurization system does not set GGH, it is proposed that use ridge-roof type demister, and the ridge-roof type of individual layer beam is removed
Day with fog is highly generally 2850mm, and the plate demister of two-stage highly accounts for for the ridge-roof type demister of 3230mm, i.e. individual layer beam
It is smaller with space, still, it is contemplated that reduce and carry water, usually require that flue gas starts to change stream at demister blade above 1m
To with improve flow velocity, so big particle can be made to fall back to demister, if plus this reserved 1m space, ridge-roof type peace
Template demister takes gross space and approached, and after gas is by wave-shaped plate demister, substantially free of mist, flue gas passes through demister
Bending channel, the drop separation carried secretly in air-flow is come out in the presence of inertia force and gravity：Flue gas after desulfurization is with one
Fixed speed flows through demister, and flue gas is rapidly, continuously changed the direction of motion, because of the effect of centrifugal force and inertia, in flue gas
Droplet strikes and is captured down on demister blade, and droplet collects to form current, because of the effect of gravity, under drop down onto slurry pool
It is interior, realize gas-liquid separation so that the flue gas for flowing through demister reaches discharge after demisting requirement.
On the basis of the technical conditions of existing demister, still there are many weak points at many aspects, in demisting
When device works, absorbent slurry is attached on demister blade, will be in leaf if slurries residence time on blade is longer
Piece surface forms dirty layer, will accelerate fouling when absorbing excessive, when flow of flue gas is uneven in absorption tower, also result in
Demister carries out fouling, once demister fouling, development is just very rapid, the presence of layer of scale reduces aisle spare, leads
Cause the flue gas flow rate at this to increase, increase the risk of secondary droplets, while still more not convenient in terms of fouling cleaning
Method, to dirt be difficult to cleaning, be inconvenient.
