Problems solved by technology

[0004] During the operation of the high-temperature heat storage system, there will be more or less leakage in the welds or seals of the pipes and equipment of the high-temperature heat storage system, so the low-boiler oil gas that is cracked or separated from the heat transfer oil will gradually accumulate in the Near the high-temperature heat storage system, if it is not removed in time, it may cause a deflagration accident

Abstract

The invention relates to the technical field of energy storage, and provides a protective device for a high-temperature heat storage system. The device comprises a flow guide pipe and a protective shed used for covering the high-temperature heat storage system, the bottom end of the flow guide pipe is fixed on the ground in the protective shed, and the top end of the flow guide pipe extends out ofthe protective shed; and a flow guide port is formed in the flow guide pipe, the flow guide port is located in the top surface, close to the protective shed, of the protective shed, and an air inletis formed in the lower part of the protective shed. According to the device, the structure is simple, and installation is convenient; and the protective device covers the high-temperature heat storagesystem, inherent leakage heat of the high-temperature heat storage system can be used for driving the leaked oil gas to be continuously discharged out of the protective shed through the flow guide pipe, so that the low-boiling-point oil gas gathered near the high-temperature heat storage system is removed in real time, an explosion accident is avoided, the driving part is not needed as well, theservice life is prolonged, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of energy storage, in particular to a protection device for a high-temperature heat storage system. Background technique [0002] The world is facing dual pressures from energy and the environment. In order to coordinate the relationship between social development and natural environment protection, it has become the consensus of people from all walks of life to vigorously develop renewable energy and increase the proportion of renewable energy in the energy structure. At present, energy storage technology is the main way to promote the development of renewable energy and solve energy supply problems. One of the most widely used and mature technologies in energy storage technology is high temperature heat storage technology. [0003] High-temperature heat storage technology has the potential for large-scale energy storage, and the heat it stores has a high grade. This heat can not only be used for energy st...
