Abstract

The invention provides a solid particulate matter heat storage and release device. The device is characterized in that a heat exchange pipe is arranged inside a heat storage and exchange container, aheat storage medium is arranged in the heat storage and exchange container and is located outside the heat exchange pipe, a heat exchange medium is circulated inside the heat exchange pipe, the heat storage medium is solid particulate matter such as sand, coal ash or coal slag. The invention further provides a solid particulate matter heat storage and release system. The system is characterized inthat the solid particulate matter heat storage and release devices are designed in a modular mode, and are divided into multiply layers in the vertical direction according to the temperature gradient, the multiple groups of the solid particulate matter heat storage and release devices are arranged at each layer in the horizontal direction, the heat exchange pipes of the solid particulate matter heat storage and release devices of the adjacent layers of the same group are connected end to end through connecting pipes, the free end of the heat exchange pipe at the bottommost layer of each groupis connected with a low-temperature medium mater pipe, and the free end of the heat exchange pipe at the uppermost layer of each group is connected with a high-temperature medium master pipe. The invention further provides a solid particulate matter heat storage and release method. The method is characterized in that a bidirectional flow design is adopted, the heat exchange medium flows from topto bottom during heat storage, and the heat exchange medium flows from bottom to top during heat release. According to the device, the system and the method, the system is simple, the maintenance is convenient, the cost is low, and the application range is wide.

Description

technical field [0001] The invention relates to a solid particle heat storage and release device, system and method, and belongs to the technical field of renewable energy storage. Background technique [0002] With the development of renewable energy power generation technologies such as solar power generation, photovoltaic power generation, and wind power generation, problems such as curtailment of light and wind are becoming more and more serious. In order to solve the problem of waste of related resources, it is necessary to configure energy storage devices for related power generation technologies. [0003] Conventional energy storage methods include molten salt energy storage, pumped water storage, flywheel energy storage, battery energy storage, and hydrogen production energy storage. Due to the high cost, small scope of application or short service life of the above technical routes, the actual use is subject to many restrictions. [0004] Therefore, it is necessar...
