Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1-Figure 3, a kind of cooling tower of the utility model, is provided with above rain belt 3 and fills out
The bed of material 1, described filler layer 1 are divided into inner region packing layer 11 and exterior domain packing layer along cooling tower radial direction from the inside to the outside
10, the packed height of the exterior domain packing layer 10 is higher than the packed height of inner region packing layer 11, and described filler layer 1 is provided with
The pitch of fins size of stuffing hole 12, the stuffing hole 12 is sequentially reduced from the inside to the outside along cooling tower radial direction, is set on the rain belt 3
It is equipped with frame body, described filler layer 1 is connected on the frame body of rain belt 3 by connection structure.
In order to reduce the gas-flow resistance of center, reaches the balance of each region, need using exterior domain packing layer 10
Packed height be higher than the packed height of inner region packing layer 11, the pitch of fins size of stuffing hole 12 is along cooling tower radial direction from interior
To being sequentially reduced outside, a pitch of fins refers to fit together after, the distance between two panels filler, currently, common packing is mostly
Referring to national standard, a most of pitch of fins is 30mm, 33mm, the packing root of well-known hot working research institute exploitation in our company the United Nations
Factually a service condition pitch of fins in border is particularly customized is processed as unequal spacing.Non- by the packed height of each region packing layer contour sets
It sets, while pine is outer tight in 12 pitch of fins of stuffing hole, to increase the heat-sinking capability of exterior domain packing layer 10, reduces inner region packing layer
11 gas-flow resistance can give full play to the heat transfer performance of cooling inner-tower filling material, improve the aerodynamic field in cooling tower, full
The Optimum Matching of air distribution and filler so as to improve radiating efficiency improves the cooling efficiency of cooling tower inside foot cooling tower.
Described filler layer 1 can be placed directly on frame body, but not limited packing layer 1, and stability is poor, be easy to produce
Raw position is mobile, can also be tied on frame body by tying up, but troublesome in poeration, time-consuming and laborious, and preferably mode is one of which,
As shown in figure 4, the connection structure includes bracket 2, the bracket 2 is connected on the frame body of rain belt 3, is arranged on the bracket 2
There are at least two sizes to be less than the gag lever post 4 of corresponding 12 pitch of fins of stuffing hole, described filler layer 1 is sheathed on bracket by stuffing hole 12
On 2 gag lever post 4.4 length of gag lever post is unsuitable too long, prevents the proper flow for influencing shower water, and size should be less than filler
12 pitch of fins of hole, when so that gag lever post 4 passing through stuffing hole 12, shower water can be still flowed out from stuffing hole 12 to be beneficial, and packing layer 1 is logical
Stuffing hole 12 is crossed to be sheathed on the gag lever post 4 of bracket 2, it is easy to operate, it is easy for installation, can not only well to packing layer 1 into
Row firm effect, and gag lever post 4 is set as at least two, can play positioning action, prevents packing layer 1 from rotating.
When gag lever post 4 is set as at least two, when packing layer 1 is installed, the stuffing hole 12 on packing layer 1 is not easy one
One correspondence is sheathed on gag lever post 4, and therefore, it is necessary to be movably arranged to gag lever post 4, preferably mode is one of which,
As shown in Figure 4, Figure 5, it is provided with criss-cross supporting beam 5 on the bracket 2, is provided in the supporting beam 5 across support
The strip through slot 6 of 5 length direction of beam, 4 bottom of gag lever post are provided with threaded hole, and the threaded hole is connected with phase therewith
The screw matched, the screw pass through strip through slot 6 from 5 bottom of supporting beam and are connected with the threaded hole of gag lever post 4.In supporting beam
Strip through slot 6 is set on 5, can be convenient screw and passed through from 5 bottom any position of supporting beam, thus the spiral shell with gag lever post 4 again
Pit is connected, and firm installation can not only be carried out to gag lever post 4, and enable to gag lever post 4 in any position of supporting beam 5
It sets and is moved, so that the stuffing hole 12 for being adapted to any position is worn, simpler convenience is installed, avoids gag lever post 4 and fills out
Material hole 12 can not correspond to the generation of installation situation.
Present inventor is issued creative labor and is just found by many experiments, the inner region packing layer 11
The ratio between packed height between exterior domain packing layer 10 is 1:1.33~1:1.66.Filler between inside and outside region packing layer
When the ratio between height is 1:1.33~1:1.66, the Optimum Matching of air distribution and filler inside cooling tower is realized, so as to improve heat dissipation effect
The cooling efficiency of rate, cooling tower is optimal.
Present inventor is issued creative labor and is just found by many experiments, the inner region packing layer 11
The ratio between region area between exterior domain packing layer 10 is 1:1.25~1:1.35.Region between inside and outside region packing layer
When area ratio is 1:1.25~1:1.35, the Optimum Matching of air distribution and filler inside cooling tower is realized, so as to improve heat dissipation effect
The cooling efficiency of rate, cooling tower is optimal.
