Heat accumulating type multi-generation unit and movable unit

Abstract

The utility model provides a 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 realizing effective utilization of waste heat and low ebb power. The movable unit comprises a container, heat accumulation material, a multi-generation component and a control system, wherein the heat accumulation material and the multi-generation unit and the control system are placed in the container; heat energy is provided for multi-generation by the heat accumulation material; the stored heat energy is converted into required energy by the multi-generation component; heat accumulation material is stored in a container; heat is exchanged between heat energy and the heat accumulation material in the container via fluids or a heat pipe; and when heat energy is required, heat energy is used via the fluid or the heat pipe. The utility model also provides a heat accumulating type multi-generation unit 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 polygeneration by using 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 sola...
