Solid grain block heat accumulating type multi-generation unit and trolley

Abstract

The utility model provides a solid grain block heat accumulating type multi-generation unit realizing low-cost and high efficient energy utilization via mutual use of various energies and heat accumulation via a heat accumulator, and in particular realize effective utilization of waste heat and low ebb power. Solid grains are employed as heat accumulating material; the solid grains are transferred to a container; at least three chambers are formed in the container, one heat accumulating chamber, one multi-generation component chamber and one control system chamber; a heat exchanging component is arranged between the solid grains and a multi-generation component; heat is exchanged between heat energy and the solid grains in the container via the fluid; and when heat energy is required, heat energy is used via the fluid. The utility model also aims to provide a solid grain block heat accumulating type multi-generation unit trolley moving the heat accumulator to an area requiring heat energy for utilization; and movable heat accumulation can be achieved.

Description

technical field [0001] The present invention relates to thermal energy utilization, in particular to a system for utilizing energy in the form of thermal energy and storing it. 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 ...
