Novel molten salt tank for heat storage

Abstract

The invention provides a novel molten salt tank for heat storage. The novel molten salt tank for heat storage comprises a tank body. The outer wall of the tank body is provided with a heat preservation layer. The top of the tank body is provided with a plurality of top connection pipes. The top connection pipes are connected with a molten salt pump, a salt inlet pipe, a salt return pipe, a liquid level meter, a pressure meter, a safety valve, a nitrogen connecting pipe and a pressure relief valve. A cylinder body of the tank body is provided with a cylinder body connection pipe. The cylinder body connection pipe is connected with an electrical heating rod. The bottom of the tank body is provided with a bottom connection pipe. The bottom connection pipe is connected with a salt output pipe. By means of the novel molten salt tank, a side plug-in electric heating rod manner is adopted, so that the heating power is large; the electric heating rod can be timely found and replaced if damaged, and daily maintenance is relatively simple; and meanwhile, the tank body is wrapped with the heat preservation layer in a unified manner, so that the heat preservation effect can be guaranteed, and the problem of pollution can be well avoided.

Description

technical field [0001] The invention relates to the technical field of heat storage and transfer, in particular to a novel molten salt tank for heat storage. Background technique [0002] With the acceleration of the industrialization process, the human demand for energy is increasing. Although traditional fossil energy has met human energy demand for a long time, its availability has gradually decreased. At the same time, the use of fossil fuels has also brought a series of environmental problems, and there is an urgent need for a new clean energy to replace traditional energy. Due to its clean and sustainable features, solar energy is gradually becoming the focus of attention, especially solar power generation technology is getting more and more attention. However, due to the intermittent nature of solar energy, it is difficult to use it for power generation to ensure the smooth operation of the power grid. Using molten salt heat storage to store the collected surplus so...
