Description
Technical field
The invention belongs to the water-treatment technology fields such as solar seawater desalination/purification sewage, more particularly, to a kind of base
The solar still of condensed water is collected in capillarity.
Background technique
Drinking Water Problem is one of the main problem that the whole world faces, and most of health problems are all due to lacking clean drink
Caused by water.And in recent decades, rainfall all over the world is insufficient, even more water salinity is caused to increase.The pollution of environment is again
It has been further exacerbated by the degree that cleaning fresh water lacks.It solves fresh water to lack one of most important means to be exactly sea water desalination.Generally
For, desalination technology is roughly divided into two classes: thermal method desalination technology and embrane method desalination technology.It is light in thermal method desalination technology
Water is to evaporate the water to obtain with condensed steam by heating seawater, these technologies are many kinds of, including multi-effect distilling (MED),
Multistage flash distillation (MSF), thermal vapor compression (TVC), mechanical vapor compression (MVC), humidification-dehumidifying (HDH) and solar still
Deng.And film desalination technology is then separated salt and water through film using selectivity.Embrane method is desalinated usually using pressure-driven salt

High absorptivity, so that the nano-fluid that nano particle and seawater/sewage are formed effectively increases the fresh water yield of system.
However, the distiller based on nanotechnology still has many problems.On the one hand due to the vapor in distiller
Condensation forms condensed water directly on glass cover-plate, and condensed water scatters the sunlight to shine in, thus significantly
The utilization of solar energy is reduced, meanwhile, the condensed water of cohesion instills seawater or waste water container again under gravity, causes cold
Condensate poor recovery effect.On the other hand, the prior art uses one-stage vaporizer, can not achieve the Multi-class propagation to solar energy, together
When, it also cannot achieve the utilization radiated by the seawater of solar energy heating or sewage, although evaporation efficiency has 80-90%, system
Overall efficiency is only less than 30%.Correspondingly, this field needs to make further improvement or improve, so that height is better achieved
Effect is driven water evaporation using solar energy and accelerates to condense, to meet the demand of modern clean drinking water.
