Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] see Figure 1-Figure 6 , a seawater desalination device applied to small ships, comprising a seawater storage tank 12 and a freshwater receiving tank 13 arranged side by side, the lower end of the seawater storage tank 12 is connected to the bottom of a seawater evaporator 23 through a seawater pipe 10, and the seawater evaporates The lower end of the device 23 is higher than the lower end of the seawater storage tank 12, and lower than the highest point of the liquid level in the seawater storage tank 12, so that the seawater water level in the seawater evaporator 23 is always kept at a suitable height, so that the seawater evaporation rate is kept at a high level. s level;

[0031] The seawater evaporator 23 is covered with a glass cover 25 in the shape of a convex lens, and the glass cover 25 seals the entire seawater evaporator 23, and the bottom of the sea...

Abstract

The invention discloses a seawater desalination plant applied to small ships. The seawater desalination plant comprises a seawater storage case and a fresh water reception case, the seawater storage case is connected to a seawater evaporation plant by a seawater pipe, the seawater evaporation plant comprises a seawater evaporator and a glass cover in convex lens shape, and the glass cover seals and covers the whole seawater evaporator; the top part of the glass cover is provided with a condenser tube, and the lower end of the condenser tube is provided with an arc anti-falling cap whose opening is downward; the inner wall of the glass cover is circularly provided with a baffle plate, the baffle plate and the glass cover form a cavity for containing fresh water, and the cavity is connected to the fresh water reception case by a water valve and a fresh water pipe; the seawater evaporation plant is internally provided with a manometer, the manometer acquires the pressure in the glass cover, and transmits the data to a display screen for displaying; the glass cover is also provided with an air valve and a waste liquid outlet; the glass cover is connected to a suction pump; the lower part of the seawater evaporator is provided with an electric hot plate. The plant has the advantages of simple structure, low energy consumption and much produced fresh water.

Description

technical field [0001] The invention belongs to the field of seawater desalination, and in particular relates to a seawater desalination device applied to small ships. Background technique [0002] There are many existing seawater desalination methods, the conventional methods are multi-stage flash evaporation, distillation, ion exchange, dialysis and reverse dialysis, etc. These seawater desalination methods are relatively mature, but they all need to consume a lot of fuel or electric energy and other energy sources, and are not suitable for seawater desalination on small ships. [0003] In view of the above problems, many devices utilizing solar energy to produce fresh water have been produced. Although the energy consumption of fresh water produced by solar energy is low, since the temperature of hot water produced by solar energy is between 85° and 100°, the amount of water vapor produced is relatively small, resulting in a relatively low rate of fresh water production ...
