摘要:

热化学吸附储热技术与传统的显热储热和相变储热技术相比具有储热密度高、热损失小和能实现跨季节储热的优点。本文综述了无机盐-水体系(也称水合盐)热化学吸附储热技术的研究现状,对典型热化学吸附材料和化学吸附反应器进行了总结。现有水合盐化学吸附体系主要包括卤盐-水和硫酸盐-水,虽然具有较高的储热密度,然而在化学吸附储热系统中使用时存在潮解导致的反应器腐蚀或膨胀结块导致的动力学性能降低等问题。以多孔材料为载体复合水合盐的方式有望解决目前存在的技术问题,提出开发新型多孔载体和化学吸附储热系统的结构优化是推动化学吸附储热技术工业化的关键。

Abstract:

The thermochemical adsorption heat storage has a higher heat storage density, a lower heat loss, and a long-term heat storage, which exhibit significant advantages over both sensible heat and phase change heat storages. This paper summarizes the developments in inorganic salt-H2O systems, called hydrated salts, for the thermochemical adsorption heat storage, including typical thermal chemisorption materials and chemisorption reactors. Hydrated salts for the thermochemical adsorption heat storage usually contain halide-H2O and sulphate-H2O. Although hydrated salts have high heat storage densities, their application in the thermochemical adsorption system still faces some problems, including the degradation of kinetic properties and reactor corrosion caused by the deliquescence and expansion agglomeration of hydrated salts. As a carrier for hydrated salts, a porous material is expected to solve the current technical problems. Moreover, the development of new porous carriers and the structural optimization of the thermochemical adsorption heat storage systems are expected as the keys to promoting the industrialization of the thermochemical adsorption heat storage technology.
