Background technique
With social development, power equipment is using more and more extensive, and national thermoelectricity installation amount is also increasing, and coal is electric
Among the flue dust and sulfide and a large amount of discharged nitrous oxides to air that unit is discharged, atmospheric environment seriously polluted, endanger
The health of people is done harm to.Thermoelectricity group of the country vigorously implements environmental transformation at present, and the technology mainly implemented is desulfurization and dedusting
Single column integrated technique needs a large amount of water as solvent in dust removal process, produces a large amount of steam, and there are also the cigarettes of part
Gas is discharged into air with steam, forms secondary pollution；Meanwhile wet absorption tower is in the process of running, is also easy to produce partial size
For white " mist " of 10 ~ 60um, " mist " not only contains moisture, it is also dissolved with sulfuric acid, sulfate, SO2 etc., therefore cleaned gas
Demisting is carried out before leaving absorption tower.
The demister generallyd use is rotational flow plate defroster, suitable for the separation of relatively coarse particle, for tiny
For droplet particles, it generally is spliced into dedusting plate face by multiple dust removing units, rotation of being beated in dust removing units using spiral, from
And increase the contact area of spiral and ash-laden gas, realize the effect of dedusting demisting.But space mistake in existing dust removing units
Greatly, spiral motion profile is too long, seriously affects dedusting defogging effect；The steam after a demisting continues up discharge simultaneously
When, it is more likely that demisting is not thorough, and the flue gas of discharge also contains corrosive gas, can not thoroughly realize the purpose of protection environment.

Distance is the sum of three dedusting spiral diameters.
Preferably, the diameter of the dedusting spiral is 38mm.
Preferably, distance of the eddy flow lid lower end surface apart from deflector upper surface is 114mm.
Preferably, the slanted angle between the helical blade and horizontal plane of the eddy flow tops is within the scope of 30-55 °.
Preferably, cooperated between the column of eddy flow lid and the positioning column of deflector by seam allowance, and solid using adhesive
It is scheduled on together.
Compared with prior art, the utility model has the beneficial effects that
1, eddy flow lid is fixed on the positioning column of deflector, eddy flow tops are provided with tangential involute along column outward
Formula helical blade, when the dust-laden steam flows upward Jing Guo demisting, under the impact of steam, the helical blade of eddy flow lid
Rotation, changes the rising rotation direction of gas, forms gyration airflow on dust removing units top, multiple units form multiple convolution gas
Stream, forms rough air at the top of desulfurizing tower, and drop is mixed through secondary collision, forms larger drop and falls into tower, is formed secondary
De- mist, improves de- butter fog effect, greatly reduces the white cigarette of outlet.
2, the dust removing units above deflector are internally provided with two layers of dedusting spiral, and eddy flow lid lower end surface is apart from flow guiding machine
The distance of structure upper surface is the sum of three dedusting spiral diameters, the activity space of dedusting spiral is greatly reduced, so that dedusting spiral
It can only float up and down in specific appropriate space, both ensure that cyclone has enough rotary moveable spaces, again limited ball
The spacing of body is little, reduces the escape space of dust-laden steam, improves efficiency of dust collection.

Specific embodiment
Embodiment with reference to the accompanying drawing is described further the utility model:
As shown in Fig. 1 ~ Fig. 3, the utility model provides a kind of integrated form dedusting except white device, including multiple dust removing units 1,
The outer profile of dust removing units 1 is positive polygon or round (such as regular hexagon), and multiple dust removing units 1 can be spliced into one layer or two
Layer dust removing units layer.
Each 1 bottom of dust removing units is equipped with deflector 2, and the dust removing units 1 of 2 top of deflector are internally provided with dedusting
Spiral 3, multiple flow-guiding channels being obliquely installed are opened up on deflector 2, and the maximum width of flow-guiding channel is less than dedusting spiral 3
Diameter falls to avoid dedusting spiral 3.2 center of deflector is fixed with positioning column 4, and 1 top of dust removing units is provided with eddy flow lid
5, the maximum outside diameter of eddy flow lid 5 is less than the inner diameter of dust removing units 1, is equipped with vertical column 6 in the middle part of eddy flow lid 5, column 6 with
The positioning column 4 of deflector 2 is cooperated by seam allowance, and is fixed together using adhesive.5 top of eddy flow lid is outside along column 6
It is provided with tangential involute screw blade 7, the slanted angle between helical blade 7 and horizontal plane works as warp within the scope of 30-55 °
When crossing the dust-laden steam flows upward an of demisting, under the impact of steam, the helical blade 7 of eddy flow lid 5 rotates, so as to change
The rising rotation direction for becoming gas, forms gyration airflow inside dust removing units 1.
The dust removing units 1 of 2 top of deflector are internally provided with two layers of dedusting spiral 3, and 5 lower end surface of eddy flow lid is apart from water conservancy diversion
The distance of 2 upper surface of mechanism is the sum of three 3 diameters of dedusting spiral, so that dedusting spiral 3 can only be in specific appropriate space
It floats up and down, both ensure that eddy flow ball has enough rotary moveable spaces, the spacing for again limiting sphere is little, reduces dust-laden
The escape space of steam, improves efficiency of dust collection.To realize that better dust removing effects, the diameter of eddy flow ball 3 are set as 38mm, eddy flow
Distance of 5 lower end surface of lid apart from 2 upper surface of deflector is 114mm.
Utility model works principle and the course of work are as follows:
In use, dust-laden steam from below is directed into dust removing units 1 by the flow-guiding channel of each dust removing units 1
Portion, treat dedusting flue gas progress water conservancy diversion using flow-guiding channel makes so that dedusting spiral 3 be pushed quickly to rotate in dust removing units 1
Air-flow forms circumferential stream, drives the internal eddy flow revolutions filled and the orientation column 4 around center to revolve, absorbing liquid droplet is revolving
Liquid film is gathered and is formed on stream 3 surface of ball, and air-flow discretization is formed dispersed phase, greatly improves mass-transfer efficiency.Dedusting simultaneously
It is movable that dedusting spiral 3 is limited in space appropriate by the eddy flow lid 5 on 1 top of unit, both ensure that eddy flow ball 3 had enough rotations
Turn activity space, the spacing for again limiting sphere is little, reduces the escape space of dust-laden steam, improves efficiency of dust collection.Top
Portion is that the eddy flow lid 5 of tangential involute screw blade 7 also makes the gas for still containing fine dust-laden drop after a demisting
Structural reform, which becomes, rises rotation direction, forms gyration airflow on 1 top of dust removing units, multiple units form multiple gyration airflows, in desulfurizing tower
Rough air is formed on top, and drop mixes through secondary collision, forms larger drop and fall into tower, forms secondary de- mist, improves
De- butter fog effect, greatly reduces the white cigarette of outlet.
