Abstract

The invention discloses a steel energy storage device which comprises an electric-heat conversion device, a heat energy storage device and a heat output device. The electric-heat conversion device is connected with the heat energy storage device which is connected with the heat output device. The heat-electric conversion device is an electric heating device used for converting electric energy into heat energy. The heat energy storage device comprises a heat storage body and a steel heat storage material arranged in the heat storage body. The steel heat storage material is multiple thick-wall steel pipes. The thick-wall steel pipes are longitudinally and vertically installed in the heat storage body in multiple rows, and a certain interval is reserved between every two thick-wall steel pipes. The heat output device is used for stably and controllably outputting and utilizing heat energy stored in the heat storage body of the heat energy storage device in the heat preservation period.

Description

technical field [0001] The invention relates to the technical field of energy storage methods, in particular to a steel energy storage device. technical background [0002] With the increasingly prominent problems of energy shortage and environmental pollution, people pay more and more attention to the utilization of new energy and the improvement of energy utilization. Energy storage technology, as an important method to solve the energy supply-demand imbalance problem, is favored by domestic and foreign enterprises and related research institutions. [0003] The heating and heat storage device in the prior art solves the safety problem of directly using high-voltage electricity to heat energy storage material water, and at the same time saves investment in transformers and reduces equipment costs. However, for heat storage with water, the temperature cannot exceed 100°C, which restricts the application range of heat storage, such as the inability to produce high-temperatu...
