Problems solved by technology

[0004] But its disadvantage is that it needs to occupy a large amount of land resources, and the second is that in winter, the intensity of solar radiation is weak, resulting in low freshwater production.

Embodiment Construction

[0034] (See Figure 5 and Fig. 6) The device of the present invention mainly includes a hull 1 that can float in water, and a lower pool 2, an upper pool 3, and a light-transmitting shed 4 are sequentially arranged in the hull; a water hole 31 is set at the bottom of the upper pool to communicate with the lower pool; A distilled water tank 32 is provided at the bottom, and the distilled water tank is communicated with the lower pool through the distilled water channel 33; an anchor ring 11 is fixed at the bottom of the hull, and the anchor ring can be connected with a cable 12 and an anchor (not shown), so that the hull can be parked in a certain sea area, especially It is an area where you can moor in high-quality sea water.

[0035] A blocking mechanism is provided in the upper pool 3, and the blocking mechanism includes a spring 34, a floating plate 35, a stay cord 36, and a plug 37 connected in sequence, wherein one end of the spring is fixed on the upper pool, and the oth...

Abstract

The invention relates to a method for preparing freshwater by applying a solar seawater desalination plant arranged on the sea. The method is characterized in that a lower pool, an upper pool and a light-transmitting shed are successively arranged in a ship body; the upper pool is provided with an air inlet mechanism and a venting mechanism; the freshwater is prepared by using a natural freezing method in the ship body in winter, and simultaneously, the seawater which is not frozen is distilled by using the air inlet mechanism and the venting mechanism so as to obtain the freshwater; and in other seasons, the freshwater is prepared by distilling the seawater with solar energy. The method has the beneficial effects that the seawater desalination plant in the invention floats in the seawater, and land resource is not occupied; the freshwater yield of the plant is higher than that of a device for distilling the seawater only by virtue of solar radiation in winter; the actions of the seawater desalination plant in the invention rely on natural force without a power plant, electric power consumption and manpower; and because the seawater desalination plant can float on the sea, thus the seawater desalination plant can freely select a high-quality seawater region to anchor for desalinating the seawater.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a method for desalinating seawater by using natural energy. Background technique [0002] Seawater desalination has always been a subject of concern. There are many methods for desalination of seawater, but the conventional methods, such as multi-stage distillation, ion exchange, dialysis, reverse osmosis membrane and refrigeration, consume a lot of fuel or electricity. Due to the global greenhouse effect and air pollution are becoming more and more serious, people are paying attention to using solar energy to desalinate seawater. [0003] Seawater desalination technology of disc solar distiller has many advantages: First, it can operate independently, not limited by steam, electric power and other conditions, no pollution, safe, stable and reliable operation, no consumption of conventional artificial energy, and it is suitable for areas with energy shortage and high environ...
