Embodiment 1

[0036] see figure 1 , In one embodiment, a particle heat absorber includes a heat absorber body and a gas supply part. Wherein, at least one heat absorption pipe is arranged in the heat absorber body. The output end of the gas supply part communicates with the bottom of the heat absorbing pipe, and is used for providing gas circulating from bottom to top into the heat absorbing pipe.

[0037] In this embodiment, a gas supply part is provided at the outlet of the heat-absorbing pipe, and the gas supply part provides a bottom-up airflow into the heat-absorbing pipe, and the airflow and the particles form a reverse flow, which can reduce the falling speed of the particles, so that The residence time of the particles in the heat absorbing pipe is prolonged, the heat exchange time is prolonged, the heat absorption efficiency of the particles is improved, and the problem of low heat absorption efficiency of the existing particle heat absorbers is solved.

[0038] At the same time,...

Embodiment 2

[0051] A solar power generation system, comprising the particle heat absorber in the first embodiment above. By communicating with the gas supply part at the outlet of the heat absorber body or the outlet of the heat absorption pipe in the heat absorber body, the gas supply part provides a bottom-up airflow to the particle heat exchange channel, and the airflow and the particles form a reverse direction. The flow can reduce the falling speed of the particles, prolong the residence time of the particles in the heat exchange channel of the particles, prolong the heat exchange time, improve the heat absorption efficiency of the particles, and solve the problem of low heat absorption efficiency of the existing particle heat absorbers. question.
