Abstract

Disclosed is a static molten salt hot air heat exchanging system. The static molten salt hot air heat exchanging system comprises a high-volume molten salt tank with good heat preservation performance, so that liquid molten salt does not need to flow and is heated inside the molten salt tank through electric heating tubes; the outer wall of the molten salt tank is directly welded with a spiral hot air passage, the outer wall of the molten salt tank inside the hot air passage is welded with rib plates, so that the heat radiating area can be enlarged; high-temperature hot air passes through a hot air / water heat exchanger, so that the heat exchanging efficiency can be improved, the heat exchanging process can be simplified, and the heat exchanging effects are easy to control. Due to the fact of being simple in structure, compared with other molten salt heat exchanging modes, the static molten salt hot air heat exchanging system has the advantages of being simple in heat exchanging process, high in heat exchanging efficiency and controllability, free from potential risks, short in construction cycle, low in investment, easy to implement and the like.

Description

technical field [0001] The invention relates to the technical field of molten salt energy storage and heat exchange, in particular to a static molten salt hot air heat exchange system. Background technique [0002] At present, the heat transfer structure of molten salt energy storage is very complicated; for molten salt energy storage and heating, high-temperature molten salt tanks, low-temperature molten salt tanks, molten salt pumps, thermal insulation and heat tracing pipes, high-temperature heat transfer, and low-temperature heat transfer are generally used. , Then hot water can be provided to the heating pipeline, heated by molten salt; stored by the molten salt pump, molten salt heater, and high-temperature molten salt tank, and the molten salt liquid in the high-temperature molten salt tank is pumped out by the molten salt pump during use The salt / heat transfer oil exchanger, and then the heat transfer oil / water exchanger heats the water, and then provides it to the h...
