AI Technical Summary

Technical Problem

In existing renewable energy storage devices, horizontal jet heating is difficult to control, posing risks of liquid column dispersion and splashing. It also requires a large footprint and the insulation material has poor stability under high temperature and pressure, leading to unstable operation and safety hazards.

Method used

It adopts a container-type electrode structure and a vertical two-stage heating method. It uses upper and lower container-type electrodes and a flow guide jet pipe to vertically spray the molten salt medium, which increases the heating power. Combined with anti-splash device and liquid level detector, it ensures the stability and safety of liquid flow.

Benefits of technology

It effectively controls liquid jet spray, reduces the risk of salt spray breakdown, improves equipment operation stability and safety, occupies a small area and has a simple structure, and is easy to maintain.

Abstract

The application provides a molten salt heater with a container electrode structure, which comprises a shell, a molten salt tank, a molten salt pump, a liquid outlet cylinder and at least one electrode heating assembly. The electrode heating assembly comprises an electrode, an upper container electrode and a lower container electrode arranged in sequence from top to bottom. The liquid outlet cylinder and the lower container electrode are connected to a zero-phase, and the upper container electrode is connected to a voltage-phase. The upper container electrode comprises an upper molten salt header and a flow guide injection pipe. The molten salt medium is vertically injected into the upper molten salt header through the electrode, the injection pipe end of the electrode vertically extends into the upper molten salt header, the molten salt medium is vertically injected into the lower container electrode through the flow guide injection pipe, the injection pipe end of the flow guide injection pipe vertically extends into the lower container electrode, and the outlet end of the lower container electrode is connected to the molten salt tank. The molten salt heater can reduce the sputtering and dispersion of the medium injection, reduce the occurrence of salt mist breakdown and ensure the stability of operation.
