Description

technical field [0001] The invention relates to the field of seawater desalination devices, in particular to a solar thermal film coupled multi-effect desalination device and method. Background technique [0002] In recent years, the shortage of fresh water resources has become an important obstacle to national development, and the development of open source and incremental technologies for fresh water resources has become a top priority. Seawater desalination using traditional energy has the problems of high investment, serious pollution, and exacerbated energy shortage. Therefore, using solar energy for seawater desalination is an important direction of technological development. [0003] At present, the existing solar desalination technology is mainly divided into two methods, one is to use a passive solar distillation device, which does not have any power components (such as pumps and fans) driven by electric energy, and does not use Active heating equipment with additi...
