Mobile heat storage device

Abstract

The invention discloses a mobile heat storage device. The mobile heat storage device comprises a heat storage water tank, a plurality of heat removal and storage balls are arranged in the heat storage water tank, a heat conduction pipe is arranged in each heat storage ball, a heat storage medium exists in each heat storage ball, the heat conduction pipes of the adjacent heat storage balls are communicated with each other, the heat conduction pipes of adjacent rows are communicated by connecting pipes, a heat storage inlet is arranged in the top of the heat storage water tank, and a heat storage outlet is arranged in the bottom of the heat storage water tank. According to the mobile heat storage device, water is used as the heat storage medium, and is larger in latent heat of phase change and nontoxic and easy to get, therefore, people do not need to worry any safety and environmental problems after leakage of the heat storage balls, in addition, a steam pressure of the water under 100 DEG C is negative pressure, and the highest pressure resistance of the heat storage balls does not exceed a barometric pressure, such that the heat storage balls do not need meet particular pressure resistance requirements. Due to a mobile design of the heat storage box body, heat storage and transfer in heat redundant regions can be realized to be used for regions or industrial processes with high heat requirements.

Description

technical field [0001] The invention relates to a mobile heat storage device, which belongs to the field of industrial heat storage and heat supply. Background technique [0002] At present, cooling is involved in the operation of different industrial production processes and equipment, and the heat of the cooling water or cooling medium after heating is often directly discharged into the air, resulting in a certain amount of energy waste. In industries such as cooling, heating, and cogeneration, there are often problems of mismatching cooling and heat, most of which are because the heat generated is significantly greater than the demand for heat. Constantly getting attention. [0003] In recent years, the phase change heat storage materials that have been developed more have been limited in application due to their high price. Secondly, similar to the traditional cold storage method, heat storage balls filled with different organic heat storage working fluids are used for ...

Problems solved by technology

[0003] In recent years, the phase change heat storage materials that have been developed more have been limited in application due to their high price. Secondly, similar to the traditional cold storage method, heat storage balls filled with different organic heat storage working fluids are used for heat storage. Toxic or flammable risks. Leakage of some thermal storage working fluids will cause environmental problems such as damage to the ozone layer or greenhouse effect, and the pressure after evaporation is relatively high. The thermal storage sphere needs to have certain pressure resistance requirements, so it is not Can be widely used

[0004] In actual production or life, there is often a mismatch between heat production and heat consumption. In some areas, a large amount of heat can be stored in the production process, but their demand for heat is very low, and in some areas, the heat demand for production or living processes is large. But there is not enough heat source, so a device is needed to store the heat in the heat surplus area and transport it to the area with greater heat demand for use

[0005] In addition, usually there is no time requirement for the heat storage process, and heat can be stored slowly, while the heat extraction process often needs to absorb the stored heat as soon as possible to provide a heat source that meets the requirements. All heat storage devices need to consider their practicability when designing, and cannot Considering the heat storage effect alone, it is also necessary to meet the heat extraction requirements
