Abstract

The embodiment of the invention discloses a multi-level solar sea water desalting device. The device comprises at least four layers: an evaporation layer at the bottom, a condensation layer on the top and two levels of fresh water collecting layers in the middle, wherein fresh water collecting grooves are formed in the condensation layer and the fresh water collecting layers and used for collecting the condensed fresh water; a clapboard between layers is provided with a vapor communicating pipe for communicating the water vapor in an upper layer and a lower layer so as to keep the same pressure between the layers; fresh water drainage pipes communicated with the fresh water collecting grooves through connecting grooves are arranged between the fresh water collecting layers and the condensation layer and between the fresh water collecting layers and used for guiding the fresh water collected in the top layer into the bottom layer. Through the embodiment of the invention, liquid in the fresh water collecting groove on the upper part of the device can be guided into the fresh water collecting groove on the bottom part level by level through the fresh water drainage pipe, and the fresh water is collected and gathered and flows into a fresh water tank for use. Meanwhile, the device realizes double functions of fresh water collection and vapor water separation by using the characteristics of the fresh water drainage pipe and the vapor communicating pipe.

Description

Technical field [0001] The invention relates to the technical field of solar energy, in particular to a multi-stage solar seawater desalination device. Background technique [0002] With the increasing depletion of world freshwater resources, desalination has become one of the most important means to solve the shortage of freshwater resources. Conventional seawater desalination is a high energy consumption industry, and the current petrochemical resources are facing the threat of being exhausted. The use of conventional energy for seawater desalination not only exacerbates the energy shortage, but also emits pollutants such as greenhouse gases and nitrogen oxides. Therefore, the use of renewable clean energy (such as solar energy) to achieve seawater desalination will become an important development direction of seawater desalination technology. An important way to solve the freshwater crisis is of great significance to ensure the sustainable development of human society. At pr...
