Direct-contact heat storage and release device utilizing heat storage material jet breakup

Abstract

The invention discloses a direct-contact heat storage and release device utilizing heat storage material jet breakup, and further discloses a direct-contact heat release system and a heat storage system utilizing heat storage material jet breakup. The direct-contact heat storage and release device comprises a metal box body; a partition plate arranged in the vertical direction is arranged in the metal box body, and the metal box body is divided into a main box body and an auxiliary box body through the partition plate; a first straight pipe section, a second straight pipe section and a 90-degree bend section which communicate with the interior of the main box body are connected with the main box body; a coiled pipe section is mounted in the auxiliary box body in the vertical direction; oneend of the coiled pipe section penetrates through an opening of the auxiliary box body and is arranged outside the auxiliary box body, and the other end of the coiled pipe section communicates with the interior of the main box body through a fourth hole in the partition plate; and the other end of the coiled pipe section communicates with the interior of the main box body through the fourth holein the partition plate. Through the device, the problem of blockage of exiting heat exchange working media can be solved, convection heat exchange in the heat storage device is enhanced, and the heatstorage and release efficiency is improved; and the structure is simple, batch production can be achieved easily, the cost is low, and the direct-contact heat storage and release device has good economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of heat storage devices, in particular to a direct contact heat storage and discharge device utilizing jet crushing of heat storage materials. Background technique [0002] At present, the composition of my country's energy consumption is still dominated by traditional fossil fuels, and the proportion of clean energy such as hydropower, wind energy and nuclear energy is only about 10%. The excessive dependence on traditional resources such as coal not only exacerbates the problem of energy shortage in our country, but also causes increasingly serious environmental problems in the process of mining and utilization. Therefore, reducing the application proportion of fossil fuels and improving and diversifying the energy composition structure have become important measures for my country to achieve sustainable development of energy and the environment. [0003] Renewable energy such as solar energy has the adva...

Problems solved by technology

Therefore, the inlet of the heat exchange fluid at the bottom is blocked by the solidified heat storage material, which hinders the normal flow of the heat exchange medium at the beginning of the next heat storage process and weakens the internal convective heat transfer.

In addition, in the existing direct contact heat storage, the contact area between the heat storage material and the heat exchange fluid is limited, how to increase the convective heat exchange area to further realize the strengthening effect of the direct contact heat exchange is an existing direct Another key problem in contact heat storage
