Description
Technical field
The present invention relates to the technical field of energy storage material, more specifically to a kind of 89 degree of phase-changing energy storage materials and its
Preparation method and application.
Background technology
The energy is the basis of human survival and development, and wherein electric energy and thermal energy are even more the energy shape that human society utilizes extensively
One of formula.At present, co-generation unit externally can not only export electric energy but also export thermal energy, can ensure exhausting and life simultaneously
The demand of electricity consumption heat in production.But due to being usually staggered with heat and peak of power consumption, when the heat of co-generation unit produces
When going out to be more than real-time heat demand, it is necessary to carry out energy storage to reduce the waste of the energy.The development of energy storage technology is be unable to do without efficiently
The exploitation of energy storage material, energy storage material can be divided into two major class.The first kind is chemical heat-accumulating material, utilizes reaction or heat of solution
Heat is stored, although storage density is bigger, heat storage capacity is limited, and pollutes environment.Second class is physics energy storage material,
It is divided into sensible heat formula and phase-change type.Wherein phase-change type is to be absorbed during material phase transformation or release heat, so as to fulfill heat
Storage and release, this material are thus referred to as phase-changing energy storage material PCM (phase change materials).
Phase-changing energy storage material has the property that:When temperature raising reaches phase transition temperature, the physics shape of phase-changing energy storage material
State changes, and the temperature of phase-changing energy storage material itself almost remains unchanged before phase transformation completion, during this, great Liang Xiang
Heating is absorbed or released out.So as in the phase transformation stage, produce a wider temperature platform, this platform goes out
It is existing so that we can obtain a metastable constant temperature time.The energy storage density of phase-change accumulation energy is high, and heat mainly divides
Cloth is near phase transition temperature, therefore practical utilize is easier.Phase-changing energy storage material possesses numerous value volume and range of product.It is general and
Phase-changing energy storage material, according to the difference of phase-changing energy storage material phase transition temperature, can be divided into low-temperature phase-change energy-storing material (15- by speech
90 DEG C), medium temperature phase-changing energy storage material (90-550 DEG C) and high-temperature phase-change energy storage material (550 DEG C of >);According to chemical composition not
Together, phase-changing energy storage material is divided into organic and Inorganic phase change energy storage material.
Specifically, inorganic molten salt is as Inorganic phase change energy storage material, it is notable the advantages of be:1. since inorganic salts are
Ionic crystal body, for solid-state or liquid, thermal conductivity is good, when being converted into liquid, due to a large amount of free ions
Presence, thermal conductivity is more preferable, and (heat conduction of substance is similar with conductivity principle, is both needed to carry out reality by the vibration of lattice and the movement of electronics
It is existing);It is easy to get 2. type is various, widely distributed, cheap;3. since polarization stronger between partial moisture and metal ion is made
It is destroyed in fusion process, needs to absorb larger heat, latent heat of phase change is big.Inorganic molten salt phase-changing energy storage material due to
Latent heat of phase change is larger in its phase transition process, phase transition temperature is constant, can store a large amount of heat, while can realize temperature control, always by
To the concern of researcher.
In recent years, it has been developed that a variety of inorganic molten salt phase-changing energy storage materials, and apply to numerous areas such as heat
Energy storage is carried out in cogeneration system.Specifically, the phase-change energy storage device in existing co-generation unit includes an energy-storage box, storage
Phase-changing energy storage material can be placed, and heat pipe is passed through energy-storage box from inlet extension, and is arranged in energy-storage box inside turn in case,
It is drawn again from exit from energy-storage box.Hot Bottomhole pressure heat-conducting medium.For example, the high temperature heat conducting medium from co-generation unit
Heat exchange occurs along the phase-changing energy storage material that heat pipe is flowed into from inlet in energy-storage box, with energy-storage box, discharges heat, Ran Houcong
It flows out in exit.
But the existing inorganic molten salt phase-changing energy storage material used still has following defect:First, inorganic-phase variable stores up
