Suspended semi submersible vertical turbine pump molten salt storage and heat exchange system

The suspended semi submersible vertical turbine pump molten salt storage and heat exchange system includes a molten salt heat exchange system, a hot salt tank, a cold salt tank, a salt drain tank, and several pipelines for interconnection. The hot salt tank is connected to the molten salt heat exchange system through the inlet pipeline of the molten salt heat exchange system, and the molten salt heat exchange system is connected to the cold salt tank through the outlet pipeline of the molten salt heat exchange system. The salt drain tank is connected to one end of the temperature regulating cold salt pipeline, and the other end of the temperature regulating cold salt pipeline is connected to the inlet pipeline of the molten salt heat exchange system. The salt drain tank is also connected to one end of the inlet pipeline of the salt drain tank, and the other end of the inlet pipeline of the salt drain tank is connected to the outlet pipeline of the molten salt heat exchange system; To solve the problem of high hot salt temperature during the start-up of the molten salt heat exchange system in existing technology, which can cause impact on the equipment and reduce its lifespan, and increase the frequency of failures; And the extraction of cold salt from the cold salt tank requires opening large holes on the cold salt tank, which reduces the reliability of the equipment, and the cost increase caused by the installation of suspended semi submersible vertical turbine pumps.
