Description
Technical field：
The utility model is related to a kind of wet method boiler flue gas desulfurization device, is specifically exactly boiler desulfurization tower demister.
Background technology：
Existing lime-gypsum wet desulfurization technology, is ring-shaped flue sulfur removal technology using void tower, is by lime slurry
Absorbing sulfur dioxide in flue reaches the purpose of sulfur dioxide qualified discharge, and little with SR after operation, desulfurized effect is bright
It is aobvious, the advantages of process stabilizing.
But desulfurizing tower exiting flue gas dust is unable to reach all the time discharge index, through checking and detecting comparison repeatedly, find
Desulfurizing tower exiting flue gas entrainment doctor solution situation is serious, and desulfurizing tower top demister can not reach the effect of cleaning flue gases, cause
Detection dust all the time beyond target, affects the normal qualified discharge of boiler smoke.
Its main cause is that desulfurizer mist eliminator is cleaned using shower water, but the cleaning of existing shower water can not completely clean work
For the ring-shaped flue that demister is used, entrainment slurries in flue gas are caused to clean up so that boiler smoke dust is all the time
Cannot qualified discharge.
Utility model content：
The utility model is exactly to overcome deficiency of the prior art, there is provided one kind have simple structure, it is easy to use,
It is easy to directly transform on existing, and improvement expenses is cheap, can improve demister efficiency, reduces pot of the flue gas containing slurries amount
Stove desulfurizer mist eliminator.
The utility model provides technical scheme below：
A kind of boiler desulfurization tower demister, including tower body, are provided with doctor solution spray equipment in tower body, in doctor solution spray
Demister on tower body above device, it is characterised in that：Described demister includes ring-shaped flue, is provided with the middle part of ring-shaped flue
Dividing plate, is provided with cleaning spraying device above dividing plate, and described cleaning spraying device is connected by pipeline with technique soft water tank
It is logical.
On the basis of above-mentioned technical proposal, there can also be technical scheme further below：
The second cleaning spraying device is additionally provided with tower body above cleaning spraying device.
The bending tubes end of described ring-shaped flue is located at the lower section of dividing plate, and the smoke end of described ring-shaped flue is located at dividing plate
Top.
Utility model advantage：
The utility model have simple structure, it is easy to use, be easy to directly transform on existing, and improvement expenses is low
Honest and clean the advantages of, demister efficiency can be particularly improved, reduce flue gas amount containing slurries, it is ensured that dust does not surpass during fume emission
Mark, safeguards the stable operation of production, while protecting the environment from pollution, improves environmental protection facility operational efficiency.
Description of the drawings：
Fig. 1 is structural representation of the present utility model.
Specific embodiment：
As shown in figure 1, a kind of boiler desulfurization tower demister, including tower body 1, described tower body 1 includes tubbiness tower body 1c,
Tower body 1c upper ends are provided with coaxial taper narrowed portion 1a, and taper narrowed portion upper end is connected with discharge flue 1b.
Boiler smoke entrance 1d is provided with the middle and lower part of tower body 1c, in the tower body 1c above smoke inlet 1d, two is provided with
The doctor solution spray equipment 2 of individual height distribution, described doctor solution spray equipment 2, including the doctor solution of concentrically round shape distribution
Pipeline disk, is evenly equipped with one group of downward shower nozzle 2a of spout on doctor solution pipeline, and each described doctor solution pipeline disk passes through
Pipeline is connected with the corresponding circulating pump 2b outside tower body 1, is connected with tower body 1c bottoms by pipeline in one end of circulating pump 2b,
To form the recycling of doctor solution.
Be provided with the dividing plate 4 of a horizontal distribution on the inwall of the tower body 1c of the top of doctor solution spray equipment 2, it is described every
Space in tower body 1c is divided into upper and lower two regions by plate 4.
One demister is set on tower body 1c, described demister includes ring-shaped flue 3, the ring-shaped flue 3 enters
Cigarette end 3a is located on the tower body inwall of the lower section of dividing plate 4, and the smoke end 3b of the ring-shaped flue 3 is located at the tower body of the top of dividing plate 4
On inwall.Two regions up and down in tower body can be connected by ring-shaped flue 3.
Cleaning spraying device 4a, described cleaning spray are provided with tower body inwall above the smoke end 3b of ring-shaped flue 3
The nozzle of device 4a upper nozzles is conical nozzle.It is additionally provided with taper narrowed portion 1a inwall above cleaning spraying device 4a
Second cleaning spraying device 4b.
The second described cleaning spraying device 4b, including the pipeline disk of concentrically round shape distribution, is evenly equipped with one on pipeline
The downward shower nozzle of group spout, and the nozzle of the shower nozzle is conical nozzle.
Described cleaning spraying device 4a and the second cleaning spraying device 4b passes through respectively pipeline with not shown work in figure
Skill soft water tank is connected.
Hollow arrow in figure is the movement locus of boiler smoke.
Operation principle：
Boiler smoke is entered and contacted with doctor solution after desulfurizing tower, and the moisture in a part of doctor solution is vaporized by high-temperature flue gas,
So that flue-gas temperature is reduced, low-temperature flue gas entrainment portions doctor solution is entered in ring-shaped flue, because the direction of gas flowing is changed
Become flow area simultaneously and also there occurs change so that the fraction slurries of flue gas entrainment to come off and splash to ring together with flue gas condensing liquid
On the inwall of shape flue.While a large amount of industrial soft waters sprayed in cleaning spraying device 4a and the second cleaning spraying device 4b is clear
Under the effect of washing, the slurries of part of smoke entrainment are displaced by technique soft water, and it is logical that then unnecessary technique soft water can enter annular
Further contact with flue gas in road, the slurries of flue gas entrainment are displaced, while cleaning to ring-shaped flue inwall.So that flue gas
The slurries of middle entrainment can be cleaned displacement totally in desulfurizing tower, so as to ensure that flue gas dust detection after desulfurizing tower does not surpass
Mark.
