Abstract

The invention discloses a solar photo-thermal low-temperature steam power electricity generating device. The solar photo-thermal low-temperature steam power electricity generating device comprises a shell body, a steam generating device body and an electricity generating device body. The top of the shell body is provided with a lens. The steam generating device body and the electricity generating device body are located below the lens. The steam generating device body is used for receiving light penetrating the lens, internally provided with low-boiling working mediums and used for driving the electricity generating device body. According to the solar photo-thermal low-temperature steam power electricity generating device, the purposes of solar low-temperature electricity generating and substantial improving of the solar comprehensive converting efficiency can be achieved.

Description

technical field [0001] The invention relates to a new energy device, in particular to a solar photothermal low-temperature steam power generation device and method. Background technique [0002] At present, fossil energy such as coal, oil, and natural gas, which are the main energy supply of human society, produces a large amount of carbon dioxide and harmful substances, and is facing the situation of exhaustion, which can no longer meet the requirements of environmental protection and sustainable development. With its huge reserves, safe and clean advantages, solar energy will become one of the new energy sources most likely to be applied on a large scale in the future. At present, there are two main development directions of solar power generation technology: photovoltaic power generation and photothermal power generation. A branch of the field of solar thermal power generation is solar low temperature power generation, which mainly utilizes solar radiation heat below 150...
