By technical field, specifically for solar power tower heat collection function.
Background technology
Solar light-heat power-generation refers to utilize large-scale heliostat array reflected sunlight, converges at connecing on high tower top
Receive on device, taken away by heat-conducting medium circulation, and produced steam by heat-exchanger rig, the technique combining traditional steam turbine generator, from
And reach the purpose of generating.
The most large-scale commercialization tower type solar electric station uses the receptor of omni-directional, typical case
Such as projects such as Solar Two, Gemasolar, barchan dunes.The advantage of this receptor is can to receive from all directions
Energy, and simple for structure, processing is relatively easy.But the difference due to heliostat field efficiency distribution region so that receptor
The heliostat arrangement difference in north and south is huge, and for the Northern Hemisphere, the mirror on the receptor north is many more than south, and this allows for receiving
The emittance focusing ratio that the thermal-collecting tube of device north side is subject to also big more than southern side, causes north side thermal-collecting tube temperature too high, and
Southern side thermal-collecting tube temperature is on the low side, and radiation is uneven with Temperature Distribution, has bigger safety in solar power station running
Hidden danger.
The mirror scene of solar power tower is amassed huge, and heliostat is numerous, and the energy density on receptor is the highest, focusing ratio
Generally more than 1000 times, focusing on the maximum region of ratio, may once occur what heat can not be taken away in time more than 1500 times
Situation, the most then make heat transfer medium (referring mainly to fused salt) decompose or deteriorate, heavy then receptor is burnt or bursts, so that
Whole system is paralysed.This problem governs the development of solar power tower always, seriously hinders tower type solar electricity
The commercialization progress stood, if publication date is on 04 16th, 2014, in the Chinese patent of Publication No. CN203550249U, open
Tower type solar thermo-power station receptor light-blocking structure, and publication date is on 09 05th, 2012, Publication No.
In the Chinese patent of CN202419967U, disclosed tower type solar energy thermal power generation station receiver etc., all can not solve the problems referred to above,
Therefore it is badly in need of finding out a kind of technology overcoming this problem.
Summary of the invention
For the radiation of tower type solar electric station receptor and non-uniform temperature, overheated burn and stress is excessive easily occurs
Situation, and provide a kind of solar power tower receiver architecture and method of reseptance.The region that focusing ratio is the highest is made relatively
Big structural adjustment, expands the endotherm area in this region, has disperseed emittance, reduces the focusing ratio on pipeline；Leak into simultaneously
The emittance of receptor opposite side (focusing ratio lower region) makes the Temperature Distribution of whole receptor the most reasonable, reduce by
The damage that or Stress non-homogeneity too high in temperature brings.

A kind of method of reseptance using described solar power tower receiver architecture, its feature is: described reception
The step of method is as follows: in tower type solar electricity generation system, and receptor is placed on high tower top, receives anti-from heliostat field
The light penetrated, medium is transported to, by pump, the tank that confluxes, then flows through receptor appearance by thermal-collecting tube from ground, accepts reflection light, real
Existing photothermal deformation；It is the high ratio region that focuses at receptor towards the region, stage casing of north side, high focuses on than the thermal-collecting tube in region inward
Recessed, referred to as indent thermal-collecting tube, the most dispersed open, when reflection light is after height focuses on than zone focusing, enter receptor
Inside cavity, progressively dissipates, and is first radiated at indent thermal-collecting tube, and reflection light, through indent thermal-collecting tube, is radiated at receptor cavity
On the thermal-collecting tube of internal opposite side (being southern side if the Northern Hemisphere), also by from southern side heliostat outside thermal-collecting tube herein
Illumination, is therefore heated the most uniform.
As preferably, the parts that can not bear radiation in receptor cavity of the present invention are put toward bottom as far as possible, it is to avoid high light
Directly radiation, or do protection process.
As preferably, the temperature measuring equipment such as the thermocouple of receptor inside cavities pipeline of the present invention preferably avoids radiation area, reduces
The measured deviation that directly illumination brings.
As preferably, the region that part optically focused of the present invention is the biggest can use the thermal-collecting tube of different materials.
The present invention compared with prior art, has the following advantages and effect: complete at the solar power tower of current main flow
On the basis of type receptor, make optimization change, focus on the layout of beam line than region by changing maximum, disperseed radiation energy
