Abstract

This invention relates to method and apparatus for preparing phase-change energy-storage microcapsules. The phase-change energy-storage microcapsules comprise encapsulating material and organic phase-change material. The encapsulating material is composed of a network polymer, which is obtained by reaction between sodium alginate and alkaline earth metal salt. The method comprises: mixing sodium alginate solution and liquid phase-change energy-storage paraffin, and encapsulating by membrane pore method to obtain microcapsules. The obtained phase-change energy-storage microcapsules have such advantages as high chemical and thermal stability, high mechanical strength, and wide applications.

Description

technical field

[0001] The invention relates to a phase change energy storage microcapsule and a preparation method and device thereof. Background technique

[0002] Energy is the basis for the existence and development of human society. With the development of social economy and the continuous improvement of people's living standards, human demand for energy is increasing, which will inevitably lead to a shortage of primary energy, especially fossil fuels. Therefore, more and more attention has been paid to recycling, storing and utilizing heat energy.

[0003] There are many thermal energy sources in production and life, such as solar energy, geothermal energy, industrial waste heat, waste heat, etc. These energy sources are characterized by a large amount, but have the disadvantages of intermittency and instability. Phase change energy storage technology utilizes the phase change latent heat of materials, which can alleviate the contradiction between energy supply and d...
