Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0029] As shown in the figure, a method for maintaining cold salt heat preservation includes an insulated cold salt tank, a pipeline heat preservation system and a rotary joint incubator. A part of the pipe body of the road is buried in the ground, and the molten salt pipeline is located on the ground. A pipe insulation system is installed on the pipeline, and a rotating interface insulation box is installed between the collectors;

[0030] Among them, the thermal insulation cold salt tank includes a tank body, an electric heater, a U-shaped heat exchange pipe and a stirring device. There is a molten salt inlet at the upper end of the tank body, and a manual maintenance inlet at the bottom of the tank body; the electric heater is an explosion-proof electric The heater, the explosion-proof electric heater is set along the vertical row, symmetrica...

Abstract

The invention discloses a method capable of maintaining cold salt heat preservation. The method comprises a heat preservation cold salt tank, a pipeline heat preservation system and a rotating connector heat preservation box. Fused salt on upper and lower layers can be adequately convected and mixed through installation of an updip stirrer and a downdip stirrer in the heat preservation cold salt tank, adequate and uniform mixing of the fused salt on the upper and lower layers in the tank is realized, and a uniform and consistent fused salt temperature is guaranteed, so it is beneficial to workstability of a generating device. The pipeline heat preservation system is capable of performing heat preservation in two modes of overground electromagnetic heat preservation and underground naturalterrestrial heat preservation, so fused salt always keeps the stable temperature in a transportation process. Each of two ends of the rotating connector heat preservation box is connected with a reflector frame structure, so excessive heat cannot be lost while the fused salt is transmitted between two heat collectors, and heat transfer efficiency of the fused salt is ensured.

Description

technical field [0001] The invention belongs to the field of heat preservation devices, in particular to a method capable of maintaining cold salt heat preservation. Background technique [0002] Molten salt energy storage technology can solve the problem of energy storage in solar thermal power generation. The technology of using molten salt energy storage directly uses electricity to heat the molten salt and store it. When needed, the molten salt releases heat, and the steam turbine converts it into Electric energy, or through the heat exchange device to release the heat stored in molten salt for heating, this makes it possible to use surplus electric energy for grid-level energy storage. The scalable energy storage technology that uses electric energy to directly heat molten salt is in the power storage market. Wide application will also help reduce the cost of solar thermal power station projects. As the key equipment in the molten salt energy storage technology, the mo...
