Description
Technical field
The invention belongs to energy storage material fused salt mixt field, more particularly to a kind of fused salt mixt heat transfer accumulation of heat working medium,
Preparation method and applications.
Background technology
The neck such as solar energy thermal-power-generating, nuclear power, high temperature accumulation of heat, heat supply and chemical industry, drying, process industrial
Domain is required to high temperature heat transfer accumulation of heat working medium.One of main application aspect of high temperature heat-transfer working medium, the i.e. sun
Can hot generation technology be developed so far from last century the eighties, used including water and steam, air or nitrogen,
A variety of heat transfer accumulation of heat working medium such as liquid metal, conduction oil and fuse salt, because fuse salt has higher use
It is temperature, high thermal stability, high specific heat capacity, high convective heat-transfer coefficient, low viscosity, low saturated vapor pressure, low
The advantage of price etc. " four high three is low ", is paid much attention to by domestic and international expert, is current solar heat power generation system
One of the main application for accumulation of heat working medium of conducting heat and developing direction.
One-component fused salt fusing point is too high, it is impossible to meet demand of the heat-transfer working medium to fusing point.Such as Chinese patent
105199678A " a kind of fused salt mixt heat transfer accumulation of heat working medium and its application ", discloses a kind of fused salt mixt heat transfer
Accumulation of heat working medium and its application, the working medium are made up of Ca (NO3) 24H2O, KNO3, NaNO3 and NaNO2；
The quality proportioning of each component is：Ca(NO3)2·4H2O：20-30wt%；KNO3：41-50wt%；NaNO3：
5-20wt%；NaNO2：10-31wt%.Several fused salts mix to be formed after eutectic fused salt mixt and can shown
The fusing point of reduction eutectic molten salt mixture is write, and can be in liquid warm area stable operation, therefore in commercial Application
Fused salt working medium is all this mixing eutectic fused salt.Solar energy thermal-power-generating, nuclear power, high temperature accumulation of heat, heat supply with
And requirement of the field such as chemical industry, drying, process industrial to accumulation of heat working medium of conducting heat is not quite similar, the present invention is carried
A kind of fused salt mixt has been supplied to meet industrial diversified high temperature heat transfer accumulation of heat working medium demand.
The content of the invention
It is mixed the invention provides one kind in order to promote application of the fused salt mixt in high temperature conducts heat hold over system
Close Molten Salt Heat Transfer accumulation of heat working medium.
In order to achieve the above object, the technical solution adopted by the present invention is, a kind of fused salt mixt conducts heat accumulation of heat work
Matter, it is characterised in that by Ca (NO3)2、KNO3、NaNO3And NaNO2Composition.
The quality proportioning of each component is：Ca(NO3)2：17.3wt%；KNO3：40-45wt%；NaNO3：
4-10wt%；NaNO2：30-38wt%, 85 DEG C of its fusing point, 590 DEG C of boiling point.
A kind of preparation method of fused salt mixt heat transfer accumulation of heat working medium, this method step is as follows：
(1) first by Ca (NO to be mixed3)2、KNO3、NaNO3And NaNO2Material distinguishes attrition grinding,
Solids Particle Diameter is less than 3cm, each material is put into rustless steel container in proportion, mix；
(2) fused salt mixt is progressively heated, and does not stop stirring simultaneously to 120 DEG C or so and kept for 10 minutes,
Moisture evaporation in fused salt mixt is fallen；
(3) 200 DEG C or so are continuously heating to and this temperature is maintained, stirring dynamics is increased, by Ca (NO3)2In
The crystallization water remove (calcium nitrate typically contains 4 crystallizations water), after vapor completely exclude after, stop stirring
After after fused salt cooling, this new mixing eutectic fused salt is that configuration is completed.
A kind of application of fused salt mixt heat transfer accumulation of heat working medium, it is characterised in that be widely used in solar heat hair
Electric energy storage, abandon wind abandon photoelectricity and " coal changes electricity " storage heating or industrial afterheat recovery storage etc. high temperature heat transfer
Accumulation of heat field.
Compared with prior art, the present invention has the advantages that：
1st, the composition cost of the preparation of fused salt mixt of the present invention is low, preparing process is extremely simple.
2nd, the hot physical property performance of fused salt mixt of the invention is highly stable, is not in a certain composition during use
Segregation phenomenon, there is good heat transfer property in liquid warm area, and less than 2 air of saturated vapour pressure
Pressure.
3rd, working medium of the invention is small to metal protection, is widely used.
4th, the present invention has stronger heat-accumulating heat-transfer ability, and better heat stability.
