Storage or the tankage or device of transport, belong to a kind of device for nitrate hydrodynamics, especially high-temperature liquid state nitre
The purification of hydrochlorate and hydrodynamics fused salt tank.
Background technology
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 employs
Solar salt fused salts are used as heat transfer heat accumulation working medium.Fused salt be fuse salt referred to as, refer to that inorganic salts melt formation at high temperature
Ion melt, with excellent heat transfer heat storage performance.Due to process is simple, low cost, simple nitrate fused salt Solar
Salt (NaNO3-KNO3,60-40wt.%), Hitec (NaNO3-KNO3-NaNO2,7-53-40wt.%), are earliest in the markets
The fused salt product of appearance.But, fused salt there is also technical problem in itself in the application, main to include being led by force due to fused salt corrosion
The material corrosion problem of cause, and the system that Volume Loss and surface losses produced by unstability under fused salt high temperature are brought is not
Stability and safe operation problem etc..Therefore, the severe corrosive and high high-temp stability for solving fused salt are fused salts in solar heat
One of key technology difficulties of new energy field such as generating.
Existing solution is launched substantially about dissolved salt purity, three aspects of material selection and system design.At present, fused salt
The control of purity, the mode purified more by traditional normal temperature water law is realized.Nitrate is in height as heat transfer heat accumulation working medium
Worked under warm environment, in use, have all kinds of corrosive impurities and enter nitrate.These corrosive impurities can cause
The stability of nitrate declines, corrosivity enhancing, ultimately results in its heat transfer thermal storage performance and changes.For these situations,
Purification is carried out under hot conditions to high-temperature liquid state nitrate to be just particularly important with hydrodynamics, but such device is with method very
It is few.
Chinese patent application 201620883954.6 discloses the bubbling air-channel system for high-purity villiaumite cleaning equipment, tool
Body ground, bubbling air-channel system of the present utility model, including：Purified gas source of the gas；As the purified gas from the purified gas source of the gas
The crucible of the reacting environment of the impurity in body and fused salt；It is arranged in the crucible, and is in fluid communication with the clarifier source of the gas,
So as to be reacted with impurity in fused salt for the purification gas from the purified gas source of the gas to be introduced into the crucible
Purify tracheae and be arranged in the gas circuit of the purification tracheae and have the stream for controlling the throughput of the purification tracheae
Amount control element.Bubbling gas circuit system response efficiency high of the present utility model, reaction is abundant, in can effectively removing fused salt
Impurity, obtains the fluoride salt solution of high-purity.
Used as one of improved technology measure, fused salt cleaning equipment uses bubbling reactor structure, blistering reaction in the patent
Device is that, with liquid phase as continuous phase, gas phase is the gas-liquid reactor of dispersed phase.Have groove profile bubbling reactor, bubbling tubular reactor,
The various structures pattern such as bubble tower, wherein bubble tower is most widely used.Liquid batch is added, and it is referred to as semicontinuous that gas is continuously passed through
Operation 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 tower is generally void tower, baffle plate is typically provided with tower, to reduce liquid dispersion；To strengthen liquid circulation and transfer reaction heat, can
If outer circulating tube and tower external heat exchanger.Filler is may also set up in bubble tower to increase gas liquid interfacial area reduction back-mixing.Gas one
As by annular gas disperser, single-hole nozzle, porous plate etc. disperse after be passed through.Gas sparging is by containing reactant or catalyst
Liquid layer realizing the reactor of liquid phase course of reaction.Bubbler is the agitator of a kind of utilization compressed air or steam.Drum
Just there is stirring action because of bubbling when compressed air or steam are passed through into liquid in bubbler.When the liquid needs heating, lead to
Enter steam more appropriate.The bubbler being placed in liquid, is generally made up of the straight tube or ring pipe of level, there is 3-6 millimeters on pipe
Aperture, be bubbling agitated liquid when compressed air or steam in hole by escaping.
Prior art lacks effective technical measures, existing use bubbler cleaning equipment letter to solving foregoing problems
Single, although suitable for the strong liquid of chemical corrosivity, but stirring efficiency is low, consumption power is more, and notably liquid not with air
Or steam generation effect, in order to avoid cause loss.
