Technical Field

Background

In the Solar photo-thermal Power generation technology (CSP), a concentrator is used to reflect Solar radiation energy to a heat collector, the heat collector converts the Solar radiation energy into heat energy, and the heat energy is used for generating electricity through a thermal cycle process. When the heat collector and the pipeline run, the heat collector and the pipeline need to be provided with devices such as a damper and the like due to a high-temperature environment, so that the vibration of the system is reduced, the safe running of equipment is ensured, and a high-temperature-resistant and radiation-resistant damping device is also needed in the nuclear energy industrial pipeline.

When the hydraulic damping shock absorber is used, due to low temperature resistance, radiation resistance and aging of the sealing ring, when the temperature is higher, oil leakage and shock absorption failure of the device are easy to occur, engineering safety is influenced, the labor intensity of workers is increased, hydraulic oil is easy to seep out, and the spring sealing ring is failed, so that although the structure is not complicated, the sealing ring is influenced by heat radiation and is easy to fail, and an ultrahigh-temperature environment cannot be realized; when the high-temperature-resistant mechanical damper is used, although the mechanical damper is full mechanical transmission damping, the materials and the heat treatment need mature processes, and the price and the cost are also advantageous, the precision is not high, and the mechanical damper is easy to explode during operation, so that the mechanical damper cannot be applied to a solar thermal power station. In a solar thermal power station, the heat absorber and the pipeline have high ambient temperature, and particularly in a heat absorption tower, especially at the position closest to the heat absorber, the hydraulic damper and the mechanical damper do not meet the use requirements and cannot meet the requirements of high temperature resistance, corrosion resistance and radiation resistance.
