Heat accumulating type stirling generator set and mobile unit

Abstract

The invention aims to provide a heat accumulating type stirling generator set; multiple energies are effectively complemented and used, and heat is accumulated by a heat accumulator, so that the energy utilization with low cost and high efficiency is realized; and in particular, such energies as various afterheat and low electricity are effectively used. The heat accumulating type stirling generator set comprises a container, a heat accumulating material, a stirling generator set and a control system, wherein the heat accumulating material, the stirling generator set and the control system are arranged in the container; the heat energy needed by the stirling generator set is provided by the heat accumulating material; the stored heat energy is converted to the needed energy by the stirling generator set; the heat exchange is performed between the heat energy and the heat accumulating material in the container through a fluid or a heat tube; and when the heat energy is needed, the heat energy is used by using the fluid or the heat tube. The invention further aims to provide a heat accumulator generator set having a move function; a heat accumulator can move to a heat energy use area; and then, the power generating use is performed.

Description

Technical field [0001] The invention relates to the utilization of thermal energy, especially after using and storing energy in the form of thermal energy, a Stirling unit is used to realize the conversion of thermal energy into electrical energy. Background technique [0002] The heat accumulator is a device for storing heat energy. The existing heat accumulators are steam and liquid heat accumulators; [0003] In the field of industrial energy saving, waste heat is recovered and stored, usually phase change technology is used for heat storage, and ice storage technology is used to achieve heat storage in low temperature areas; [0004] In the field of solar energy, molten salt is used to store heat. Although molten salt can be stored at high temperatures, it needs to be converted from solid to liquid, so thermal energy is required to heat it. At the same time, the toxicity, economy and safety of molten salt are also problematic. Therefore, the use of molten salt heat storage is li...

AI Technical Summary

Problems solved by technology

[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 other gases are also used for heat storage, but its thermal fusion is small, and large-scale thermal energy storage cannot be realized

[0006] The energy storage power station uses electric energy for storage, especially the electric energy composed of wind power and photovoltaic, because it cannot be stored, it has to be discarded in large quantities, causing a lot of waste
