The utility model provides a sunlight gathers can sea water desalination device suitable for island reef or platform, mainly include light and heat vapourizing unit, locate spotlight mechanism and the gathering mechanism around the light and heat vapourizing unit, and with the heat transfer that light and heat vapourizing unit steam outlet communicates condense the water installation, the heat transfer congeals the water installation and introduces the sea water and leads to in the light and heat vapourizing unit, spotlight mechanism focuses on the sunlight to gathering the sea water region in mechanism and/or the light and heat vapourizing unit, gather the sunlight that will focus and assemble the sea water region in the light and heat vapourizing unit, light and heat vapourizing unit's steam outlet and heat transfer congeal the water installation and communicate. The seawater desalination device adopts the first-stage or more light gathering mechanisms and the energy gathering mechanisms, directly heats seawater by utilizing focused light heat energy at the temperature of 80-700 ℃, and reduces the heat exchange process as much as possible, thereby avoiding a large amount of energy loss in the heat exchange process, greatly improving the seawater desalination efficiency, and having simpler and more compact equipment structure. |
