Connecting tube, so that absorbing pipe, the small header of transition, connecting tube, the temperature distribution gradients that converge on four components of header are smaller, it is adjacent
Temperature difference between two components is smaller, so as to reduce thermal stress suffered by each component, reduces each element joints
The risk leaked.
2, in conventional heat dump, absorbing pipe directly with converge header and be connected to, once any one absorbing pipe with converge
The junction of header leaks, and is required to shut down entire heat dump, and the present invention is by introducing multiple small headers of transition, when certain
It, can be by control means by the small header of the transition broken down when the junction of the small header of one transition and absorbing pipe leaks
And corresponding absorbing pipe is removed from the normal work of heat dump, to can guarantee the normal operation of heat dump other parts, is mentioned
The high reliability of heat dump, extends the generating dutation of entire electricity generation system, simultaneously, moreover it is possible to reduce because heat dump is shut down suddenly
The impact of the expensive components such as heat exchanger, steam turbine, generator to entire electricity generation system rear end.

It is described in further detail.According to following explanation and claims, advantages and features of the invention will be become apparent from.
Referring to Fig. 1 and Fig. 2, in one embodiment, a kind of heat dump tube panel component for tower type solar energy thermal power generation,
Converge on including: header 1, under converge header 5.At least two upper connector groups 2, upper connector group 2 include connecting at least two
Adapter tube, the first end of each upper connector are connected to header 1 is above converged;At least two lower connector groups 6, lower connector group 6 are wrapped
At least two lower connectors are included, the first end of each lower connector is converged header 5 under and is connected to;The small header of transition at least two
3, the second end of each upper connector is connected to the small header 3 of upper transition;At least two lower small headers 7 of transition, each lower connector
Second end be connected to the small header 7 of lower transition;Absorb heat tube panel, is composed of several absorbing pipe groups, absorbing pipe group includes several
Absorbing pipe 4, each absorbing pipe 4 include upper bend loss, lower bend loss and the straight tube between upper bend loss and lower bend loss
Section, the upper bend loss of absorbing pipe 4 are connected to the small header 3 of upper transition, and the lower bend loss of absorbing pipe 4 is connected to the small header 7 of lower transition.
If the circumferential adjacent small header length of transition is identical, need to there are fixed offset distance, deviation along its axis direction
4 overall diameter of absorbing pipe that distance is one times;If the adjacent small header length of transition of the circumferential direction is not identical, must assure that
Single absorbing pipe 4 in the small header of transition one times of deviation of 44 overall diameter of absorbing pipe each other.Using this design, transition just can guarantee
The absorbing pipe 4 connected in small header only passes through single angle bending in same plane without the multi-angle bending in three-dimensional space
Gapless 4 row of absorbing pipe can be formed, design, the complexity of manufacture are greatly simplified.Upper connector group 2 and upper connector group
2 include at least two connecting tubes.Individually the upper small header 3 of transition or the small header 7 of lower transition by least two connecting tubes with it is upper
Converge header 1 or under converge header 5 and be attached, specifically, being located at the small header 3 of upper transition or the small collection of lower transition of two side positions
Case 7 respectively by four connecting tubes with above converge header 1 or under converge header 5 and connect, positioned above converge header 1 or under converge header
Immediately below 5 or the small header of transition of surface is connect by three connecting tubes with header is converged.Because being located at the upper transition of two sides
Small header 3 or the small header 7 of lower transition need to by curved connecting tube with above converge header 1 or under converge header 5 and connect, it is curved
Connecting tube will increase fluid resistance, so being located at the small header 3 of upper transition or the respectively piece connection of increase of the small header 7 of lower transition of two sides
Pipe, using this design, can make to converge header 1 or under converge hot working fluid in header 5 it is more uniform enter transition

The connecting pipe structure of the small header 3 of transition or the small header 7 of lower transition in introducing, so that temperature gradient, which is dispersed in, converges header, connection
On pipe, the small header of transition and absorbing pipe 4, stair-stepping distribution, the wall thickness and 4 wall of absorbing pipe of the small header of transition is presented in four temperature
Thickness difference is smaller, and temperature variation curve is more close, does not have the biggish temperature difference, therefore will not generate biggish thermal stress;
Converge header from connecting tube since wall thickness is different, temperature difference is mainly reflected in connecting tube and converges at the weld bond of header, still
Connection thickness of pipe wall is thicker, and the ability for bearing thermal stress and heat fatigue is relatively stronger, can greatly reduce due to thermal stress band
The booster risk come, so tower-type solar thermal hair can be greatly improved by the transitional function of the small header of transition and connecting tube
The service life of electric heat dump.In addition, conventional heat absorber converges even if there is the problem of cracking at the leg as caused by thermal stress

The connection structure for converging header Yu absorbing pipe 4 for tower type solar energy thermal power generation heat dump of the invention, when generation leakage accident
When, it is only necessary to the connecting tube group of the small header of priority check transition with converge at the weld bond of header, heat dump converge header with
There is bigger space between the connecting tube of the small header of transition, also relatively more easy maintenance and replacement works.And this structure is very big
Ground, which simplifies, designs and manufactures the period, and from the header introducing small header of transition is converged, it is curved directly not need complicated space for connecting tube
Pipe, not only reduces tube fluid resistance, reduces flow deviation in pipe, prevent 4 local temperature of absorbing pipe excessively high and booster, and
And also greatly reduce design, the complexity of manufacture and production cost.
In conventional heat dump, absorbing pipe 4 directly with converge header and be connected to, once any one absorbing pipe 4 with converge
The junction of header leaks, and is required to shut down entire heat dump, and the present invention is by introducing multiple small headers of transition, when certain
It, can be by control means by the small collection of the transition broken down when the junction of one small header of transition and absorbing pipe 4 leaks
Case and corresponding absorbing pipe 4 are removed from the normal work of heat dump, thus can guarantee the normal operation of heat dump other parts,
The reliability for improving heat dump extends the generating dutation of entire electricity generation system, simultaneously, moreover it is possible to reduce because heat dump stops suddenly
Impact of the machine to expensive components such as heat exchanger, steam turbine, the generators of entire electricity generation system rear end.In conventional heat dump,
Every absorbing pipe 4 with converge header and be connected to, need to open up a large amount of intercommunicating pore on converging header, greatly reduce and converge collection
The intensity of case, the present invention is by the introducing small header of transition, then header is forwarded to and converged by connecting tube, due to the number of connecting tube
