Problems solved by technology

[0004] However, the seawater desalination system of this device belongs to the traditional solar distillation system, which cannot float, cannot perform automatic water replenishment and salt discharge, cannot effectively condense, and does not have automatic water replenishment and salt discharge functions. Large-scale planting requires more manpower and material resources Seawater replenishment and concentrated brine discharge cannot achieve fully passive operation, and thus cannot form an integrated fully automatic system

Embodiment 1

[0039] Such as figure 1 As shown, a fully automatic floating platform for seawater desalination and irrigation, including a full passive solar distillation module, an irrigation module, a connection module and a buoyancy device for connecting the full passive solar distillation module and the irrigation module;

[0040] The fully passive solar distillation module includes a rectangular water tank with an open upper end. The water tank is filled with seawater. The water tank is equipped with an automatic water replenishment evaporator. The automatic water replenishment evaporator includes a board wall, a foam block, and fiber cotton cloth. The blocks are distributed on the upper surface of the board wall, and the fiber cotton cloth is covered on the board wall and the upper surface of the foam block; a rectangular limit bar is set above the automatic water replenishment evaporator, one end of the limit bar is connected with the inner wall of the water tank near the daylighting p...

Embodiment 2

[0044] An application of a fully automatic floating platform integrating seawater desalination and irrigation, which applies the fully automatic floating platform integrating seawater desalination and irrigation to cover a large area of ​​sea surface for seawater desalination and sea planting.

[0045] Floating on the water surface when working, the automatic replenishment evaporator relies on capillary suction to automatically absorb seawater from the bottom during the evaporation process, and relies on the reverse diffusion of salt to discharge excess salt, and then performs fully passive seawater desalination and planting. Modular expansion can be carried out for large-scale applications, and the purpose of preventing seawater intrusion can be achieved by covering a large area of ​​the sea.

Embodiment 3

[0047] A fully automatic floating platform integrating seawater desalination and irrigation, the difference from Example 1 is that the water storage part is filled with 900g of soil and 100g of water, and the mass-number ratio of soil and hydrogel is 9:1, and the rest Features are the same as in Example 1.

Abstract

The invention discloses a seawater desalination and irrigation integrated full-automatic floating platform and application thereof, and relates to the technical field of sea water desalination and irrigation energy conservation and emission reduction. The seawater desalination and irrigation integrated full-automatic floating platform comprises a full-passive solar distillation module, an irrigation module, a connecting module and a buoyancy device; the full-passive solar distillation module comprises a water tank, an automatic water supplementing evaporator, a collecting tank, a daylighting panel, a condensation plate and a baffle plate; the automatic water supplementing evaporator comprises a plate wall, a foam block and fiber cotton cloth; a heat conducting plate is arranged at one end,away from the daylighting panel, of the condensation plate and extends into the water tank; the lower surface of the daylighting panel is coated with a transparent anti-fog coating; the irrigation module comprises a water storage part containing soil and hydrogel, and the mass part ratio of the soil to the hydrogel is 10: 1-2: 1; the connecting module comprises a sliding groove and a pipeline. The buoyancy device comprises a plurality of floating blocks. The floating platform is applied to sea water desalination, offshore planting and full-passive sea water evaporation, improves the light energy utilization rate and the sea water evaporation efficiency, prevents sea water from flowing backwards, facilitates later maintenance, and achieves full-automatic integration of the floating platform.

Description

technical field [0001] The invention relates to the technical field of seawater desalination and irrigation energy saving and emission reduction, in particular to a fully automatic floating platform integrating seawater desalination and irrigation and its application. Background technique [0002] At present, the food problem in the world is serious. The traditional agricultural model is limited by the area of ​​arable land, the growth environment and the cost of manpower. It is increasingly unable to meet the needs of human beings. The problem of excessive freshwater resources occupied by crop irrigation is also becoming more and more prominent. The ocean has a vast space, sufficient light, and abundant water sources. It is an ideal place to solve current problems and create a new agricultural model. The marine environment has certain advantages, but it is a difficult problem to design a feasible and efficient marine planting plan to overcome seawater desalination, freshwat...
