Abstract

The invention discloses a solid salt heating and melting device and method. The solid salt heating and melting device comprises a container body, a container cover and an electrode group. The lower portion of the container body is closed, and the upper portion is opened. The container cover seals the upper portion of the container body. The electrode group is fixed to the container cover. The container body is a heat exchange jacket and is used for cooling the inner wall of the container body so as to form a frozen salt wall. The solid salt heating and melting device further comprises a continuous heating device and a discharge pipe. The continuous heating device penetrates through the container cover. The discharge pipe is fixed to the container cover. The electrode group and the discharge pipe extend to the bottom of the container body. The electrode group comprises a plurality of bar-shaped electrodes. The electrodes are arrayed to form a polygonal prism. The distances between the lower ends of the electrodes can be adjusted.

Description

technical field [0001] The invention relates to the field of molten salt heating equipment, in particular to a solid salt heating and melting device and method. Background technique [0002] Molten salt is an excellent heat transfer and heat storage medium, which has the advantages of high operating temperature, large specific heat capacity, good thermal stability, high convective heat transfer coefficient, low viscosity, low saturated vapor pressure, and low price. Heat and heat storage technology. [0003] In large-scale heat storage engineering projects, the solid salt melts from the initial solid state into a liquid state and heats up to the use temperature, requiring the use of a heating and melting device. Traditional heating of molten salt generally uses resistance-type molten salt furnaces. Due to the heat conduction of electric heating wires, the heating speed is slow, the melting time is long, and the heat loss is large, and the heating power increases with the in...
