Background

Energy conservation is an important component of the basic national policy of energy conservation and emission reduction in China, and is a long-term strategic task of sustainable development of national economy and society in China. As a big energy consumption country, one of the outstanding problems of China is low energy utilization rate and serious waste. The reasonable utilization of the industrial flue gas waste heat can improve the energy utilization efficiency and effectively save energy, for example, the waste heat is used for preheating furnace charge and combustion air to improve the combustion efficiency of a boiler, and the flue gas waste heat can also be used for producing high-temperature hot water and steam for daily life and production heat. However, the utilization of the waste heat of the flue gas is restricted by a plurality of factors, the production process has certain periodicity, so that the waste heat resource is intermittent, in addition, the flue gas temperature greatly fluctuates in one use period, and the fluctuation of the waste heat resource is caused, so that the recycling of the waste heat becomes difficult. Therefore, in order to better utilize the waste heat, a heat storage technology is needed to play the roles of energy conservation and consumption reduction. The heat storage method can be generally divided into sensible heat storage, latent heat storage and chemical reaction heat storage. Latent heat storage can store a large amount of energy through phase change of materials under the condition that the volume of the heat storage material is relatively small, relatively small temperature change can be guaranteed in the heat storage process, and the heat transfer working medium has relatively stable temperature in the heat release process, so that the latent heat storage has a wider application prospect. When the latent heat storage technology is adopted, firstly, the selection of a suitable heat storage material is considered, for example, the phase change temperature of the heat storage material is adapted to the use temperature; high thermal conductivity; non-toxic, non-flammable and non-explosive; the raw materials are rich and cheap, and the adoption of a high-efficiency, safe and cheap heat accumulator is also considered to be important.

Patent No. CN209197547U on the china patent net has better heat retaining effect, in this equipment, because hot water and steam are inside the heat accumulator, the surface is all very hot, though heat insulation measure has all been taken to general heat accumulator, it is general that the coating is more, the effect is not very good, if touch carelessly, still scald easily, still have overflow liquid on the one hand still to special pipeline and local discharge, also can cause certain waste, for this reason, a solution that can solve above-mentioned problem urgently needs.
