A heat absorber tube-panel assembly for tower-type solar thermal power generation

Abstract

The invention discloses a heat absorber tube panel assembly for tower type solar thermal power generation. The heat absorber tube panel assembly for tower type solar thermal power generation comprisesa convergence header, a plurality of connecting pipe groups, a plurality of transition small headers and a plurality of heat absorption pipe groups. The connecting pipe groups comprise a plurality ofconnecting pipes, the connecting pipes are arranged in the same plane, and the first end of each connecting pipe communicates with the convergence header. The second end of each connecting pipe communicates with the corresponding transition small header. The heat absorption pipe groups comprise a plurality of heat absorption pipes, and the heat absorption pipes communicate with the transition small headers. The deviation distance between the projections of the axes of the adjacent transition small headers on the horizontal plane is greater than or equal to the size of the outer diameter of the heat absorption pipes. The connecting pipe groups comprise at least two connecting pipes. The connecting pipe structures of the transition small headers are introduced, so that the temperature gradient is dispersed on the convergence header, the connecting pipes, the transition small headers and the heat absorption pipes, and the service life of a tower type solar thermal power generation heat absorber is prolonged.

Description

technical field [0001] The invention belongs to the technical field of clean energy, and in particular relates to a heat absorber tube-panel assembly for tower-type solar thermal power generation. Background technique [0002] While the economy continues to develop, energy is increasingly in short supply, traditional non-renewable energy is increasingly exhausted, and economic development is increasingly constrained by the development and utilization of energy. The utilization of renewable energy has attracted widespread attention, especially the utilization of solar energy has attracted more attention from the world. [0003] Solar thermal power generation is a major way of utilizing solar energy at present. At present, solar thermal power generation can be divided into tower solar thermal power generation, trough solar thermal power generation, and dish solar thermal power generation according to the solar energy collection method. [0004] In the field of solar thermal p...
