Description
Technical field
The present invention relates to waste heat boiler structure, specially a kind of tube plate structure of vertical exhaust-heat boiler.
Background technology
With the popularization of distributed energy, the market prospects of small-sized waste heat boiler are more and more wide, if continuing big in
Type boiler Experience Design manufactures, and can cause being significantly increased for cost.Us are at this time just forced to ensure boiler parameter and peace
On the basis of complete, optimization design, accomplish " getting twice the result with half the effort ".It is competing that we only have continuous cost efficiency fully to participate in market
Strive.
The content of the invention
For above-mentioned technical problem, the present invention proposes a kind of tube plate structure of vertical exhaust-heat boiler, and its is simple in construction, adds
Work is convenient, and cost is low.
Its technical scheme is such：A kind of tube plate structure of vertical exhaust-heat boiler, it includes tube sheet body, and its feature exists
In being provided with middle groove among the tube sheet body, the middle groove upper end is provided with upper strata pipe mounting hole, lower end is provided with lower floor
Pipe mounting hole, the tube sheet body left side, right side, lower end are provided with groove, and the tube sheet body top and bottom are provided with suspension rod
Connecting hole.
It is further characterized by, and the middle groove is rectangular channel；
The groove of the tube sheet body lower end is located at the underface of the rectangular channel；
The groove on the left of the tube sheet body and right side is between the upper strata pipe mounting hole and lower floor's pipe mounting hole.
After structure using the present invention, maximum stress is less than material allowable stress, meets to require, original plurality of plates is connected
Connect and make a present whole plate into, only need to process several grooves, simple in construction, easy to process, cost is low.

Embodiment
As shown in Figure 6, a kind of tube plate structure of vertical exhaust-heat boiler, it includes tube sheet body 1, opened among tube sheet body 1
There is middle groove 2, the middle upper end of groove 2 is provided with upper strata pipe mounting hole 3, lower end is provided with lower floor's pipe mounting hole 4, and tube sheet body 1 is left
Side, right side, lower end are provided with groove 5, and the top and bottom of tube sheet body 1 are provided with suspension rod connecting hole 6.Middle groove 2 is rectangular channel；
The groove 5 of the lower end of tube sheet body 1 is located at the underface of rectangular channel；The groove on the left side of tube sheet body 1 and right side is located at upper strata Guan An
Fill between hole 3 and lower floor's pipe mounting hole 4.
Analyzed with reference to specific experiment：
A certain run in early stage module number is a lot, if every layer of module is all individually designed, then just needs to supply respective numbers
Transportation frame（Run in early stage does not reclaim）And substantial amounts of suspension rod, and multiple lifting module is also required in erecting bed, increase
Installation workload.However we have found that the weight of every layer of module of the project is not very heavy, and between module distance compared with
Closely, root shares a tube sheet it is contemplated that similar two layers of module can be merged into a big module by us, and in width
Tube sheet is integrally formed by direction.
Specific design scheme is illustrated in fig. 2 shown below, below we just need verify the program feasibility.
We simulate the stressing conditions under tube sheet working condition with ANSYS first.
Modeled according to preliminary project, as shown in Figure 3, tube plate thickness T=18mm；Length：L=2851.5mm；Highly：H=
3214mm.Upper end suspension rod perforate D1=Φ 36mm；Lower end suspension rod perforate D2=Φ 32mm.Extended surface tube perforate D3=Φ 36mm, perforate are horizontal
To spacing x=158mm；Vertical spacing y=91mm.Loading temperature, load, boundary condition simultaneously solve, as a result as shown in Figure 4.From should
It can be seen that, tube sheet entirety stressing conditions substantially conform to intensity requirement, are only answered at upper layer module bottom opening in trying hard to
Power is concentrated, and equivalent stress exceeds material working strength, is dangerous destruction point.Increase tube plate thickness or change boom location go out
Existing kindred circumstances；Temperature field is deleted, stress concentration disappears, and analyze influences to cause for thermal stress.Temperature Distribution schematic diagram such as Fig. 5 institutes
Show, module region, Temperature Distribution is distributed for uniform gradient, but two layers of module intermediate region is same temperature.Tube sheet heat
Region is mutated between expansion in the module, has also resulted in stress concentration.
Influenceed to weaken the thermal stress of edge tapping, we change tube plate structure and see Fig. 6, establish model such as Fig. 7 institutes
Show, and load solution as shown in figure 8, Temperature Distribution signal from tube sheet stress figure as shown in figure 9, can be seen that former stress concentration
Area substantially weakens after tube sheet cutting, and maximum stress is less than material allowable stress, judges that the tube sheet after improvement meets expection.
We have found in the design, and with the miniaturization of waste heat boiler, size, the weight of integral module are all more remaining than medium-and-large-sized
Heat boiler is small, and we can do some improvement in the hanging of module, then it is proposed that following contemplate：
Fixed as far as possible using monoblock tube sheet with previous module, reduce segmentation manufacture；
In the case of conditions permit, module not at the same level is connected using monoblock tube sheet, reduces suspension rod dosage.
But we can also face problems with：
The increase of extended surface tube quantity, the influence to tube sheet and suspension rod intensity are hung on tube sheet；
The increase of tube sheet height, inevitably result in the tube sheet upper and lower ends temperature difference and increase, in same tube sheet, the influence of thermal stress is just
It can increase；
With the increase of tube sheet height, width, whether tube sheet edge thermal expansion amount is in allowed band.
By the improvement of the last present invention, solve the problems, such as above-mentioned, reached expected purpose.
