The tankage or device of storage or transport, belong to a kind of device for nitrate hydrodynamics, especially high-temperature liquid state nitre
The purification and hydrodynamics fused salt tank of hydrochlorate.
Background technique
In the application first batch of solar energy thermal-power-generating project that China announces a few days ago, the power station for having more than half is used
Solar salt fused salt is as heat transfer heat accumulation working medium.Fused salt, that is, fuse salt referred to as, refers to that inorganic salts melt formation at high temperature
Ion melt has excellent heat transfer heat storage performance.Due to simple process, at low cost, simple nitrate fused salt Solar
Salt (NaNO3-KNO3,60-40wt.%), Hitec (NaNO3-KNO3-NaNO2,7-53-40wt.%) are earliest in the market
The fused salt product of appearance.But there is also technical problems in itself in the application for fused salt, mainly include since fused salt corrosion is led by force
Volume Loss produced by the material corrosion problem of cause and the unstability under fused salt high temperature and surface losses bring system are not
Stability and safe operation problem etc..Therefore, it solves the strong corrosive of fused salt and high high-temp stability is fused salt in solar heat
One of key technology difficulties of new energy fields such as power generation.
Existing solution designs three aspects with system substantially about dissolved salt purity, material selection and is unfolded.Currently, fused salt

The various structures pattern such as bubble tower, wherein bubble tower is most widely used.Liquid batch is added, and gas is continuously passed through referred to as semicontinuous
Operate bubble tower.The bubble tower gas and liquid of continuous operation are continuously added to, and flow direction can be upward cocurrent or countercurrent.Drum
Bubble column is mostly void tower, is equipped with baffle, generally in tower to reduce liquid dispersion；It, can to reinforce liquid circulation and transfer reaction heat
If outer circulating tube and tower external heat exchanger.Filler be may also set up in bubble tower to increase gas liquid interfacial area and reduce back-mixing.Gas one
As by annular gas disperser, single-hole nozzle, porous plate etc. dispersion after be passed through.Gas sparging is by containing reactant or catalyst
Liquid layer to realize the reactor of liquid phase reaction process.Bubbler is a kind of using compressed air or the blender of steam.Drum
Just because of bubbling stirring action occurs for bubbler when compressed air or steam are passed through liquid.When the liquid needs to heat, lead to
It is more appropriate to enter steam.The bubbler being placed in liquid is usually made of horizontal straight tube or ring pipe, 3-6 millimeters of Guan Shangyou
Aperture, be bubbled when compressed air or steam in hole by escaping and stir liquid.
The prior art lacks effective technical measures to foregoing problems are solved, existing using the letter of bubbler cleaning equipment
Single, although being suitable for the strong liquid of chemical corrosivity, stirring efficiency is low, and consumption power is more, and notably liquid not with air
Or steam generation effect, in order to avoid cause to lose.
