Abstract

The utility model aims to provide a two-cavity fluid heating transferring and accumulating system comprising heat accumulating material, a housing, warming material and a fluid. The two-cavity fluid heating transferring and accumulating system comprises at least two cavity chambers, one heat accumulating cavity chamber and one heat exchanging cavity chamber; the heat accumulating material is disposed in the heat accumulating cavity chamber and heat energy is stored therein; the heat exchanging cavity chamber is provided with at least one group of inlet and outlet; fluid exchanging heat with a heat source is a first fluid; the first fluid exchanges heat with the heat accumulating material and then flows out of the outlet; when heat energy in a heat accumulator is required, a second fluid with temperature lower than temperature of the heat accumulating material flows from the inlet of the heat exchanging cavity chamber into the heat accumulator; and the second fluid exchanges with the heat accumulating material and then flows out of the outlet, so heat energy is utilized. Two cavity chambers are utilized to achieve heat source storage and utilization; and the two-cavity fluid heating transferring and accumulating system is suitable for storage of heat with temperature of 0 to 1200 DEG C.

Description

technical field [0001] The invention relates to thermal energy utilization, in particular to a system for realizing heat storage and heating utilization of thermal energy. Background technique [0002] The heat accumulator is a device for storing thermal energy, and the existing heat accumulators are steam type and liquid heat accumulators; [0003] In the field of industrial energy conservation, waste heat is recovered and stored, usually using phase change technology for heat storage, and in the low temperature field using ice storage technology for heat storage; [0004] In the field of solar energy, molten salt is used to store heat. Although molten salt can achieve high temperature storage, it needs heat energy to heat it because it needs to be transformed from solid to liquid. At the same time, there are problems with the toxicity, economy, and safety of molten salt. , so the use of molten salt heat storage is limited. [0005] In the field of solar energy, air or ot...
