Abstract
The invention provides a use method of a fused salt initial fusion and dormancy solidification prevention and resuscitation system. The system comprises a feed device, a salt fusing tank, a dormancy tank and a high-temperature salt storage tank. The discharge port of the feed device is connected with the salt inlet of the salt fusing tank. The salt fusing tank is connected with the high-temperature salt storage tank through a salt fusion pipe. The salt fusing tank is connected with the dormancy tank through an overflow pipe. The dormancy tank is connected with the salt fusing tank through a salt liquid pipe. The high-temperature salt storage tank is connected with the dormancy tank through a salt discharge pipe. The method is composed of three parts, during initial fusion, solid salt enters the salt fusing tank to be heated and fused into fused salt and is then conveyed to the high-temperature salt storage tank; during dormancy solidification prevention, the fused salt and deionized water are mixed into a saline solution, and because the solidifying point of the saline solution is low, the system can be prevented from freezing; during resuscitation, the saline solution in the dormancy tank is conveyed to the salt fusing tank to he heated, fused salt is left after all water molecules in the saline solution are evaporated, and the fused salt is conveyed to the high-temperature salt storage tank to be used. By means of the use method, the advantages of the functions of solid salt initial fusion, fused salt dormancy solidification prevention, resuscitation and the like can be achieved.
Description
technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to a molten salt initial melting and dormant anti-coagulation and recovery system and a use method thereof. Background technique [0002] Molten salt is a molten liquid of inorganic salt, which is a sensible heat storage medium suitable for medium and high temperature energy storage systems. Molten salt has the advantages of large temperature range, high specific heat capacity, low steam pressure, good heat transfer performance, good chemical stability, environmental protection and pollution-free, and low price, so it is widely used in the fields of new energy, energy saving and emission reduction. [0003] At present, there are still many technical problems to be solved in the engineering application of molten salt heat transfer and heat storage. Before molten salt, the solid salt particles need to be initially melted, and then the molten salt can be used for he...
