Abstract

The invention relates to a high-temperature liquid-state nitrate purification and performance enhancement fusing tank. A filtering plate (4) is horizontally arranged inside a tank body (2), a hollow stirring rod (16) is arranged in the middle of the top of the tank body (2) towards the tank body (2), the lower end of the hollow stirring rod (16) is positioned on the upper side of the filtering plate (4), a stirring paddle (3) is arranged on the lower end of the hollow stirring rod (16), the lower end of the hollow stirring rod (16) is connected with a bubbler (5) which downwards penetrates through the filtering plate (4). Dry air, carbon dioxide and nitrogen gas are sequentially fed, the stirring paddle (3) is used for stirring while the bubbler (5) conducts gas introduction, and through the coordinated and reasonable structure arrangement of the stirring paddle and the bubbler and by bubbling, stirring, filtering, additive addition and the like under the high-temperature melting state, the purification function of high nitrate can be realized, the impurity removal and purification rate of the fused salt is up to 97%, the high-temperature thermal stability of nitrate can be enhanced, and the corrosivity of nitrate can be reduced. The stirring and homogenization time is short, and the high-temperature liquid-state nitrate purification and performance enhancement fusing tank is energy-saving, environment-friendly, safe and high in efficiency.

Description

technical field [0001] The present invention relates to C01B9 / 00 general method for preparing halides in IPC classification or B65D container equipment or device for storage or transportation of objects or materials, and belongs to a device for performance enhancement of nitrate, especially high-temperature liquid nitrate Purification and performance enhancement of molten salt tanks. Background technique [0002] Among the first batch of solar thermal power generation projects announced in China before the application date, more than half of the power stations used solar salt molten salt as heat transfer and heat storage working medium. Molten salt, short for molten salt, refers to the ionic melt formed by melting inorganic salt at high temperature, which has excellent heat transfer and heat storage performance. Due to the simple process and low cost, the simple nitrate molten salt Solarsalt (NaNO3-KNO3, 60-40wt.%) and Hitec (NaNO3-KNO3-NaNO2, 7-53-40wt.%) are the earliest ...
