Send out condensation chamber.Saline slot is designed in the arch face outer wall of hot water storing tank and evaporative condenser chamber at different levels, seawater passes through seawater water inlet pipe not
Disconnected supplement.The downside arch face and device plate outer side of hot water storing tank is respectively designed with insulating layer and insulation board, reduces the damage of heat
It loses.It is also devised with fresh water salt water demarcation plate on the inside of device bottom plate, fresh water and strong brine are separated, it is defeated to be separately connected fresh water
Outlet pipe and strong brine efferent duct.
Working principle is: vacuum tube solar heating element collects sunlight and provides heat for the fresh water in hot water storing tank, should
Heat is reached in first order evaporative condenser chamber by hot water storing tank's wall, heats the sea on the outside of bucket wall in saline slot first there
Water generates evaporation, and steam generates fresh water in the inside outer wall condensation of first order evaporative condenser chamber, and the latent heat for condensing release is used for
The seawater in second level evaporative condenser chamber in saline slot is heated, generation is evaporated again, successively transmitted heat outward step by step, step by step
Generate fresh water.The fresh water of generation enters the fresh-water tank of this grade of distiller bottom, and remaining concentrated seawater flows into strong brine slot, and respectively
It is exported by fresh water efferent duct and concentrated seawater efferent duct.
The utility model has the advantages that
It (1) is the energy, environmental protection and energy saving using solar energy.
(2) it is improved while reducing system energy consumption using the sensible heat of the latent heat of vaporization of vapor and high-temperature water to greatest extent
The energy utilization rate of system.
