Description
Technical field
The present invention relates to demister technical field, more particularly to a kind of fixed knot of parallel combinations type spiral board demister
Structure.
Background technology
Rotational flow plate defroster is that, using the density contrast between gas-liquid, the centrifugal force produced by flow rotation makes drop (contain
Dust) from air-flow separate, the computing formula of centrifugal force shows, the size of the certain dust of quality and centrifugal force suffered by droplet
Inversely proportional with radius of turn, the more big then centrifugal force of radius is smaller, and separating effect is poorer.Illustrate the small spiral board of diameter than straight
The big spiral board separative efficiency in footpath is high.
However, fume desulfurizing tower is all diameter from several meters to more than 20 meters of large-scale tower, this is unsuitable with eddy flow board diameter
Excessive very contradiction, has promoted parallel combinations rotational flow plate defroster technology in large-scale or super-huge desulfuration absorbing tower at this stage
Using being exactly briefly using multiple small-diameter unit rotational flow plate defroster parallel combinations (patent No.s in large-scale tower：
ZL201220723758.4)。
The parallel combinations rotational flow plate defroster load mode for using at present has two kinds：First, made using stainless steel plate, will
Several rotational flow plate defroster units are fixed in supporting plate circular hole, and supporting plate both played a supportive role, and also sealed.2nd, make
Made of MODIFIED PP, by several or even hundreds of rotational flow plate defroster unit cylinders, each is fixed on and opens circle of parallelepiped
On hole plate base, by parallelepiped flat base as cellular splicing is integral, large-scale tower edge exposed position is with blind
Plate is sealed.Parallelepiped flat base is seated on the grid welded by stainless steel strip as cellular splicing is integral, overall
Lived by large-scale tower internal loading beam load again.
Several rotational flow plate defroster units are fixed in supporting plate circular hole, due to being that stainless steel makes, structure
Stabilization, but install complicated；And parallelepiped flat base is used as cellular splicing is integral, can be due to large-scale tower
Interior operation dynamic pressure, causes cylinder large area lodging phenomenon often to occur.
The content of the invention
It is an object of the invention to regarding to the issue above, there is provided a kind of fixation of parallel combinations type spiral board demister
Structure, is applicable in large-scale tower, assembles rapidly and efficiently, Stability Analysis of Structures.
The object of the present invention is achieved like this：
A kind of fixed structure of parallel combinations type spiral board demister, it is characterised in that the parallel combinations type eddy flow
Plate demister is arranged in a combination by some rotational flow plate defroster units, each rotational flow plate defroster unit include cylinder with it is parallel
The base of hexagon, is equipped with spiral board in cylinder；It is parallel in tower body support beam in large desulfurization tower to set up some
Strut, some rotational flow plate defroster units are respectively across being fixed on adjacent two support bars, and some rotational flow plate defroster lists
The base of unit is in each other honeycomb arrangement.
Wherein, the base center of the rotational flow plate defroster unit is provided with circular hole, and the circumference along circular hole on base is provided with
One encloses the flanging perpendicular to base, and barrel jacket is mutually fixed outside flanging with flanging.
Wherein, the base and cylinder of the rotational flow plate defroster unit are made by MODIFIED PP material, and base and cylinder
Between be fixed using the bolt of PP materials.
Wherein, the support bar is stainless steel square tube or carbon steel outer lining MODIFIED PP square tube.
Wherein, the circular hole inner side of the base of the rotational flow plate defroster unit is uniformly provided with six symmetrical fixing points, should
When base is across on adjacent two support bars, the straight line that the fixing point that two of which is oppositely arranged is linked to be is located at two support bars
The axis of symmetry on, remaining four fixing point is located at two both sides of support bar two-by-two respectively, and two positioned at the same side are solid
The line of fixed point is parallel with support bar, will be located at the fixing point of base of the same side and close therewith respectively using two fixtures
Support bar be fixed, and further using bolt base and support bar are fixed as one.
Wherein, the bolt is made up of PP materials.
Beneficial effects of the present invention are：The base and cylinder of rotational flow plate defroster unit used can be standardized, scale
Production, production efficiency is high；Using the support bar of PP materials, the requirement to the levelness of support bar is reduced；Whole combined rotation
The installation rate for flowing plate demister is fast.
Brief description of the drawings
Fig. 1 is the part-structure figure after parallel combinations type spiral board demister installation.
Fig. 2 is the attachment structure figure between rotational flow plate defroster unit and support bar.
Specific embodiment
With reference to specific embodiments and the drawings, the present invention is expanded on further.
As shown in Figure 1 with Figure 2, a kind of fixed structure of combined spiral board demister, the parallel combinations type rotation
Stream plate demister is arranged in a combination by some rotational flow plate defroster units 1, and each rotational flow plate defroster unit 1 includes cylinder 11
With the base 12 of parallelepiped, base 12 and cylinder 11 are made by MODIFIED PP material, and spiral board, bottom are equipped with cylinder 11
12 centers of seat are provided with circular hole, and flanging of the circle perpendicular to base 12 is provided with along the circumference of circular hole on base 12, and cylinder 11 is enclosed within
The outer bolt and the flanging of base 12 between using PP materials of the flanging of base 12 is fixed；Tower in large desulfurization tower
Parallel in body support beam 2 to set up some support bars 3, some rotational flow plate defroster units 1 are respectively across being fixed on adjacent two branch
On strut 3, and the base 12 of some rotational flow plate defroster units 1 is in each other honeycomb arrangement.
Support bar therein 3 can select stainless steel square tube, and reduce the levelness to support bar, preferably outside carbon steel
Serve as a contrast the square tube of MODIFIED PP.
To make whole parallel combinations type spiral board demister quickly be assembled in large desulfurization tower, and Stability Analysis of Structures,
Six symmetrical fixing points are uniformly provided with the inside of the circular hole of the base 12 of rotational flow plate defroster unit 1, the base 12 across
When on adjacent two support bars 3, the straight line that the fixing point that two of which is oppositely arranged is linked to be is located at two symmetry axis of support bar 3
On line, remaining four fixing point is located at two both sides of support bar 3 two-by-two respectively, and two root anchor points positioned at the same side company
Line is parallel with support bar 3, will be located at the fixing point and branch close therewith of the base 12 of the same side respectively using two fixtures
Strut 3 is fixed, and further using bolt base 12 and support bar 3 is fixed as one.
This fixed structure so that the fixation of rotational flow plate defroster unit both has singulation, again can be under special circumstances
Avoid the effect occurrence of large-area lodging problem because of dynamic pressure.
If by taking certain power plant 16.5m desulfurizing towers as an example, if a set of simultaneously using the grid installation that existing stainless steel strip makes
Row combination rotational flow plate defroster, the requirement for horizontality to load beam is high, and otherwise grid out-of-flatness is difficult to Fast Installation a set of
Parallel combinations rotational flow plate defroster, the general set-up time is 45 days.But, using the fixed structure in the present invention, to support bar
Requirement for horizontality it is not high, i.e. the ability with self adaptation, installation rate is fast, and the general set-up time is less than 10 days.
