Seawater desalting device

Abstract

The invention discloses a seawater desalting device. The seawater desalting device comprises a seawater storing device, an evaporation condensation room and a fresh water storing device, wherein the seawater storing device is connected with the evaporation condensation room through a seawater pipe; the evaporation condensation room is connected with the fresh water storing device through a fresh water pipe; the evaporation condensation room is internally provided with a semiconductor chilling plate; the energy of the semiconductor chilling plate is supplied by an energy supplying device; and the seawater storing device is provided with a normal-pressure keeping opening. The seawater desalting device disclosed by the invention is small in volume, light in weight and high in efficiency; the seawater desalting device can be continuously and automatically operated so that the seawater desalting device is particularly suitable for coastal regions with sufficient wind power resources and solar energy, and other external energy sources are not needed, namely a water lacking problem of parts of islands can be solved.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination, and in particular relates to a seawater desalination device. Background technique [0002] Fresh water is an indispensable basic material for human survival and production. The total water reserves in the world are 1.388 billion km 3 The amount of seawater accounts for more than 97% of it. Due to the high salinity of seawater, humans cannot drink it directly. The total amount of remaining freshwater accounts for about 2.53% of the total water storage on the earth. Not only that, even in such a small proportion of fresh water, its distribution is extremely uneven. 98.8% of the fresh water is frozen in the glaciers in the north and south poles and alpine regions of the earth, and exists in rivers, lakes and groundwater The fresh water that can be directly used by human beings is less than 0.36% of the total fresh water on the earth. my country has a long coastline, and many islands...

AI Technical Summary

Problems solved by technology

However, this device only uses the cooling end of the semiconductor cooling chip to condense fresh water, and its cooling capacity is not enough to balance the total heating capacity of the heating end, which will eventually cause the temperature inside the entire device to continue to heat up and damage the semiconductor cooling chip

Therefore, this device can only be used for short-term and a small amount of desalination of seawater by manpower in extreme cases, and cannot continuously provide fresh water.
