Abstract

The invention discloses a solar photothermal low-temperature steam power generation device. The device includes a housing, a steam generating device and a power generating device. A lens is arranged on the top of the housing, and the steam generating device and the power generating device are located below the lens. The steam generating device is used to receive the light passing through the lens, and the steam generating device is equipped with a low-boiling point working fluid for driving the power generation device. The invention can realize the low-temperature power generation of solar energy and greatly improve the comprehensive conversion efficiency of solar energy.

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...
