Specific embodiment
Features described above and advantage to enable the present invention becomes apparent, special embodiment below, and coordinates institute's accompanying drawing to make
Describe in detail as follows.
The present embodiment provides a kind of multilamellar ellipse bar turbulence device, is installed in desulfuration absorbing tower, rapid for improving flue gas
Stream effect, as shown in Figure 1.This turbulence device 2 is particularly located at the lower section of spraying layer 1 of desulfuration absorbing tower, with spraying layer apart from P=
1.5~2.5m, concrete numerical value is selected according to actual needs, and the present embodiment selects 2m.Compared to the global design of prior art, this rapids
The stream difference of device 2 is to adopt modularized design, is conducive to installation and removal, and it is by support 21 and on support 21
Multiple turbulent flow modules 22 are constituted, as shown in Fig. 2 each of which turbulent flow module 22 passes through overlapping edges on the stent 21, by spiral shell
The connected modes such as bolt, clamping are detachably connected.When somewhere is damaged, it is not necessary to change to overall, only need to change module at this
, change convenient and low cost.Each turbulent flow module 22 grows 1.4~1.8m, wide 0.8~1m, with specific reference to being actually needed
It is fixed, long 1.5m, wide 1m are selected in the present embodiment.It is pointed out that because desulfuration absorbing tower cross section is circle, above-mentioned length is a width of
Standard module size, according to circular edge situation, can select suitable nonstandard modules, and the nonstandard modules can be by required size
Design and manufacture, it is readily appreciated that, without the need for superfluous words.
Each turbulent flow module includes the turbulent flow grid of multilayer parallel arrangement, and by taking two-layer as an example, turbulent flow grid are by multiple for the present embodiment
The ellipse bar composition of placement (i.e. major axis is horizontally oriented) is lied down, Fig. 1 is seen, for ease of clearly showing that, turbulence device 2 is entered in figure
Amplification is gone.Adjacent two layers turbulent flow grid apart from H=80mm~120mm, select according to actual needs, the present embodiment select
100mm。
In 0 °~90 ° angle arrangements, the angle ellipse bar can be referred in level between the ellipse bar of adjacent two layers turbulent flow grid
Projection angle on face.Fig. 3 is the partial schematic diagram of 0 ° of angle arrangement of two-layer ellipse bar, and for ease of differentiating, upper strata ellipse bar is
Solid line represents that lower floor's ellipse bar is represented (Fig. 4, Fig. 5 are similar) for dotted line, and 0 ° of angle is arranged to belong to and is arranged in parallel, and is to increase turbulent flow
Effect adopts interlaced arrangement simultaneously, so-called staggeredly to refer to two-layer ellipse bar offset, i.e., if Tu3Zhong lower floors ellipse bar is positioned at upper
Between layer ellipse bar space.Fig. 4 is the partial schematic diagram of 45 ° of angle arrangements of two-layer ellipse bar.Fig. 5 is 90 ° of angles of two-layer ellipse bar
The partial schematic diagram of arrangement, 90 ° of angle arrangements are arranged vertically.
As shown in figure 3, width (i.e. long axis length) D=60mm~65mm of ellipse bar.Prior art is proved turbulent flow grid
Turbulence effects are optimal when percent opening ψ is 30%~60%, because percent opening is equal to the ratio of hole area and the gross area, can use ψ=L/
(L+D) calculate, wherein L is pitch-row (pitch-row between i.e. adjacent two ellipse bar from), and further L=ψ D/ (1- ψ), is computed
Pitch-row L=25.7mm~97.5mm.So that percent opening ψ is for 50% as an example, it is then 60mm that D selects 60mm, L to the present embodiment.
Difference from prior art is that the ellipse (cross sectional shape of elliptical tube or ellipse bar) of prior art is such as figure
Setting shown in 6 is placed, and the ellipse of the present invention is as shown in Figure 7 to lie down placement.The advantage for lying down placement is：First, cigarette
Gas can be erect and stop little to flue gas when placing when rising through oval surface (as shown in the arrow of Fig. 6, Fig. 7), and flue gas holds very much
Easily pass through from both sides, it is little to flue gas annoyance level；And big is stopped to flue gas when lying down placement, flue gas need to one section of both sides multirow away from
It is big to the annoyance level of flue gas from just rising through；But it should be noted that, ellipse lies down placement than general flat board (not
Diagram) effect is good, although this is because flat board can also increase flue gas walking path, the resistance of flat board is excessive, and lies down placement
Oval surface more meet that gas is streamlined, have the resultant effect for reducing resistance with increasing flue gas walking path concurrently；Ellipse is lied down
Place and placed and flat board compared to oval setting, the annoyance level and lifting desulfuration efficiency to flue gas is maximum；2nd, erect and put
Put upper and lower thickness big, it is little to lie down the upper and lower thickness of placement, in the case of percent opening identical, erect that to place material requested more, increase
Manufacturing cost, it is little to lie down placement material requested, saves manufacturing cost；In addition, lying down placement compared to no rib for flat board
Angle, is not in the situation of corner angle corrosion.
The oval flatness of ellipse bar is the of the invention mostly important parameter to be proposed, its to flue gas turbulence effects with take off
Sulphur efficiency all has an impact.Present invention provide that oval flatness is the ratio of transverse and short axle, i.e. f=a/b, wherein, f is ellipse
Round flat Pingdu, a is major axis, and b is short axle, as shown in Figure 7.Oval flatness f can be adopted to represent oval flat with oval eccentricity e
Flat degree, but f is more directly perceived, and the relation of the two is e2+1/f2=1.Jing Fluent modelings learn, oval flatness f with
There is interference relation in desulfuration efficiency η, that is, exist an optimum f codomain so that η is maximum, the optimum f codomains for 2~10, η >=
98.4%, η average than other situations is higher by least one percentage point, and this is significant for desulfurization.Detailed data such as following table institute
Show：
| Oval flatness | 1 | 1.5 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| Desulfuration efficiency % | 97.5 | 97.7 | 98.4 | 98.8 | 98.9 | 98.8 | 98.9 | 98.7 | 98.6 | 98.5 | 98.5 |
| Oval flatness | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | |
| Desulfuration efficiency % | 98.1 | 98.1 | 98 | 98.1 | 98 | 98 | 97.9 | 97.8 | 97.8 | 97.7 |
Table 1
Graph of relation of the desulfuration efficiency with regard to oval flatness is drawn according to above-mentioned table 1, as shown in figure 8, can from figure
Know, when f is between 2~10, η contains a peak, and f ＜ 2 and f ＞ 10, η can diminish.Wherein, the situation of f ＜ 2 includes three
Kind：One is 1 ＜ f ＜ 2, as f=1.5, η=97.7%；Two is f=1 in broad terms, and this is positive round, η=97.5%；Three
It is f ＜ 1 in broad terms, represents oval and place to erect, it can be seen from the curvilinear trend simulated in Fig. 8, η ＜ 97.5%.F ＞
10 situation includes two kinds：One is 10 ＜ f ＜+∞, from curvilinear trend in Fig. 8, ηF=14＜ 98.1%, at least ηF=10＜
98.5%；Two is that f is+∞, and practical significance is that now ellipse becomes flat board, it is clear that seen according to curvilinear trend, ηF=14＜ 98.1%,
At least ηF=10＜ 98.5%.Why there is peak, trace it to its cause be the scope (f=2~10) oval surface increase
Optimal solution is obtained between smoke path and reduction resistance.
Fluent simulation drawings when Fig. 9 is 3 for oval flatness, Fluent simulation drawings when Figure 10 is 1.5 for oval flatness,
Can be seen that by two figures, the former to flue gas turbulence effects more preferably, the result of simulation as shown above, η=98.8% during f=3, f=
η=97.7% when 1.5, the former is higher than the latter 1.1 percentage points.The Fluent simulation drawings of other numerical value and analysis are similar, no longer
Repeat one by one, it should thus be appreciated that.
