Abstract

The invention discloses a solar seawater desalination device. The solar seawater desalination device comprises a seawater evaporating chamber, a condensed water collecting cover, a micro-hole heat collecting evaporating sheet, and an annular water tank. The condensed water collecting cover is arranged in the upper part of the seawater evaporating chamber and is used to collect evaporated water steam in the seawater evaporating chamber. The upper cover plate of the condensed water collecting cover is obliquely arranged. The lower part of the condensed water collecting cover is provided with the annular water tank, which is used to collect the water collected by the condensed water collecting cover. The micro-hole heat collecting evaporating sheet is arranged on the upper surface of seawater in the seawater evaporating chamber. One end of the lower part of the seawater evaporating chamber is provided with a seawater inlet, and the other end is provided with a condensed water collection opening, which is arranged in the bottom of the annular water tank. The provided solar seawater desalination device can improve the solar seawater desalination efficiency and yield.

Description

technical field [0001] The invention belongs to the field of seawater desalination, and relates to a solar seawater desalination device. Background technique [0002] Water is the source of life, and the reserves of fresh water that human beings rely on for survival only account for 2.53% of the total water in the world. With the deepening of economic globalization and the acceleration of industrialization, the global demand for fresh water resources is increasing; Yes, the distribution of water resources in my country is uneven, and the salinity of the soil in some areas has seriously caused water shortages. Seawater reserves are abundant, investment and development are relatively economical, and the technology of using clean energy such as solar energy for seawater desalination is conducive to energy conservation and emission reduction. The structure of the existing seawater desalination device is very complex and expensive. Among them, the device for desalination of seaw...
