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

Embodiment 1

[0053] Example 1. Mobile concrete heating and heat storage vehicle

[0054] figure 1 It contains a container 3 and concrete 4. The concrete is put into the container and waits for it to solidify. The container 3 is provided with a fluid inlet 6 and a fluid outlet 7. The fluid is heated by the heating device 5 and then sent from the inlet 6 to the container In 3, there are a plurality of pipes 8 between the inlet and outlet of the fluid, and the inlet 6 and the outlet 7 are connected to each other through the pipe. The fluid can flow in the pipe 8, and heat exchange with the concrete through the pipe 8 set inside the container , The concrete after heat exchange is stored for thermal energy;

[0055] The heat accumulator can be used to store heat locally or be moved to the required area; when the heat energy in the heat accumulator needs to be used, the fluid whose temperature is lower than the concrete of the heat accumulator flows in from the inlet 6, and the low temperature fluid ...

[0059] Embodiment 2. A fixed concrete heating accumulator

[0060] figure 2 The fixed concrete heating accumulator shown includes a container 3, a heat source 10 and a heating device 5. The concrete is put into the container and waits for it to solidify. The container 3 is provided with a fluid inlet 6 and a fluid outlet 7. A plurality of pipes 8 are also arranged between the inlet and the outlet of the container 3, and the inlet 6 and the outlet 7 are connected to each other through the pipes, so that the fluid can flow in the pipe 8;

[0061] The heat accumulator can be used to store heat locally or be moved to areas where it is needed;

[0062] When the heat energy in the heat accumulator needs to be used, the fluid whose temperature is lower than that of the concrete flows in from the inlet 6, and then flows out through the outlet 7 after heat exchange with the concrete to realize the utilization of heat energy;

[0063] When the thermal energy of the concrete reaches the set te...

Abstract

The invention aims to provide a concrete heating heat accumulator, which can realize the heat accumulation with high temperature, large scale, low cost and high efficiency, and is suitable for the heat accumulation at a temperature of 10-1500 DEG C. The concrete heating heat accumulator comprises a container, concrete, an insulation material, a shell and the like, wherein a pipe is additionally arranged between an inlet and an outlet in the container, and is used for communicating the inlet with the outlet; the concrete is cured in the container by using the heat accumulating capacity of the concrete; the heat exchange is realized through a pipe arranged in the concrete; a fluid enters from a heat accumulating inlet and flows out from an outlet of the heat accumulator to realize the heat accumulation and the utilization of the heat accumulator; and a heating device and a heat source are arranged for providing a heated high-temperature fluid to the concrete so as to heat the concrete. The invention further aims to provide a concrete heating heat accumulating vehicle; and the heat accumulator can move to a heat energy area for use to realize mobile heat accumulation.

Description

Technical field [0001] The invention relates to the utilization of thermal energy, in particular to the use of concrete to achieve thermal energy absorption, storage, exchange and utilization. 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 the low temperature field; [0004] In the field of solar energy, molten salt is used for heat storage. 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 limited. [0005] In the field of solar energy, ai...
