Abstract

The invention discloses an adjustable chemical heat storage system and belongs to the technical field of heat storage. The adjustable chemical heat storage system comprises a steam generator, a steam mass flowmeter, a reaction kettle, a heat exchanger, a vacuum pump and heat storage materials, wherein the steam generator, the reaction kettle and the vacuum pump are connected in sequence; the steam mass flowmeter is arranged between the steam generator and the reaction kettle; the heat storage materials are arranged in the reaction kettle; the heat exchanger makes contact with the heat storage materials; the heat storage materials are obtained by mixing Ca(OH)2 and compounds containing Li. According to the adjustable chemical heat storage system, the heat storage density is large, the stability is good, the cost is low, the chemical energy storage requirement can be well met, and the adjustable chemical heat storage system can be applied to solar heat storage and recycling and industrial waste heat recycling.

Description

Technical field [0001] The invention relates to a technology in the field of heat storage, in particular to a controllable chemical heat storage system. Background technique [0002] Heat storage technology is an important technology to improve energy utilization efficiency and protect the environment. It can be used to solve the contradiction between thermal energy supply and demand mismatch. It has a wide range of fields in power "shifting peaks and filling valleys", solar energy utilization, waste heat and waste heat recovery and utilization. Application prospects. Chemical heat storage has the advantages of high energy storage density and wide operating temperature range among many heat storage methods, but the control and regulation of heat storage and heat release are poor. [0003] After searching the prior art, it was found that Chinese Patent Document No. CN101644548A, published (Announcement) Date 2010.02.10, discloses a high-temperature chemical heat storage element and...
