Description
Technical field
The invention belongs to material technical field of memory more particularly to a kind of storage tank and for solar light-heat power-generation system
Storage tank.
Background technique
Solar light-heat power-generation technology is the important directions that solar energy scale utilizes, and solves fossil energy danger to the mankind
The problems such as machine, air pollution, has far-reaching significance.The working medium that solar light-heat power-generation uses has water (water vapour), fused salt, sky
Gas, conduction oil, liquid metal and other heat-conducting mediums etc..Wherein, due to the fluctuation of solar irradiation and discontinuity, solar energy
There must be extensive heat reservoir could continuous and stable electric generation in solar-thermal generating system.Heat reservoir is by being stored using storage tank
Heat-storage medium, and by solar energy heating heat-storage medium, solar energy is stored in heat-storage medium, in sunlight
When according to deficiency or needing heat, by discharging the heat being stored in heat-storage medium, to realize the indirect utilization to solar energy.
Fused salt has using the characteristics such as temperature is high, temperature range is wide, flow behavior is good, thermal capacity is big, is applied to heat accumulation as heat accumulation working medium
The unstable problem of solar irradiation can be just made up in system, be the solar energy heat-storage working medium being most widely used at present.
For storing the equipment of heat-storage medium fused salt storage tank, the storage tank for storing high-temperature molten salt is used for hot salt cellar
Store the storage tank of low-temperature molten salt is cold salt cellar.Either cold salt cellar or hot salt cellar, storage tank are all by storage tank bottom plate, tank wall
Plate, storage tank top plate are constituted.
Traditional storage tank uses single layer tank, and stave sheets and storage tank bottom plate pass through welded connecting.However it is used for photo-thermal power generation
The storage tank of system often bulky, temperature alternating is frequent, and the load that storage tank is born is complicated and unstable.A large amount of heat accumulations are stored to be situated between
The storage tank of matter not only needs to bear medium bring fluid column static pressure in itself, still suffers from huge angular force caused by strong wind,
Snow load caused by heavy snow weather, simultaneously, it is necessary to be able to bear earthquake angular force and interior media caused by under earthquake operating condition
The external forces such as rolling fluid wave is dynamic.The whole most weak region of storage tank is usually located at the junction of stave sheets and storage tank bottom plate,
By being welded together, the weld seam of formation is fillet weld for stave sheets and storage tank bottom plate.Meanwhile fillet weld be also easy to by
It is stored in the corrosion of the heat-storage medium in storage tank, accelerates the failure of fillet weld, so that the reliability of storage tank itself is poor.
