Nanocomposite energy storage ball and preparation method thereof

Abstract

The invention discloses a nanocomposite energy storage ball and a preparation method thereof. The nanocomposite energy storage ball is prepared from 60 to 70 percent of nanocomposite material and 30 to 40 percent of refractory material, wherein the nanocomposite material is prepared from the raw materials as follows: 4 to 6 percent of nano-graphite powder, 15 to 18 percent of nano-coke powder, 38 to 42 percent of nano ferric oxide powder, 4 to 6 percent of nano-copper powder, 8 to 12 percent of nano-aluminum powder, 4 to 6 percent of nano-silica powder and the balance of nano calcium chloride powder; and the refractory material is prepared from 80 to 90 percent of refractory clay and 10 to 20 percent of refractory cement. The nanocomposite energy storage ball prepared according to the formula has high density, long heat release time and large heat release quantity, can be made into ball-shaped structures of different sizes, is applied to hotel kitchen ranges conveniently, and has energy gathering and energy storage effects.

Description

technical field [0001] The invention relates to the technical field of nanometer energy storage, in particular to a nanocomposite energy storage ball and a preparation method thereof. [0002] Background technique [0003] Thermal energy storage technology is used to solve the contradiction between thermal energy supply and demand, and is an important technology to improve energy utilization and protect the environment. It has good application prospects in the fields of solar energy utilization, "peak shifting and valley filling" of electricity, waste heat and waste heat recovery, and energy saving of industrial and civil building heating and air conditioning. [0004] Compared with the developed countries in the world, there are obvious differences in the composition of my country's energy consumption sector. The composition of energy consumption in developed countries is roughly as follows: 1 / 3 of industry, 1 / 3 of transportation, and 1 / 3 of construction industry. Althou...

AI Technical Summary

Problems solved by technology

Due to the shortcomings of sensible heat energy storage system, such as low energy storage density, bulky equipment, and heat storage that cannot maintain a constant temperature, it has limitations in industrial waste heat recovery.

Phase change latent heat energy storage uses the inherent heat capacity of the substance and the phase change heat of the state change to store thermal energy at the same time, and has an energy storage density that is at least an order of magnitude higher than the sensible heat energy storage system, but this method generally has supercooling And the shortcomings of phase separation, there are also great limitations in industrial waste heat recovery
