A fully automatic floating platform integrating seawater desalination and irrigation and its application

Abstract

The invention discloses a fully automatic floating platform integrating seawater desalination and irrigation and its application, and relates to the technical field of seawater desalination and irrigation energy saving and emission reduction, including a full passive solar distillation module, an irrigation module, a connection module and a buoyancy device; a full passive solar energy The distillation module includes a water tank, an automatic water replenishment evaporator, a collection tank, a daylighting plate, a condensation plate, and a baffle; the automatic water replenishment evaporator includes a board wall, a foam block, and a fiber cotton cloth. The end of the condensation plate away from the daylighting plate is provided with a heat conduction plate extending to the inside of the water tank ; The lower surface of the lighting board is coated with a transparent anti-fog coating; the irrigation module includes a water storage part filled with soil and hydrogel, and the mass-to-number ratio of soil and hydrogel is 10:1 to 2:1; the connection module Including chute, pipeline, buoyancy device including several floating blocks; used in seawater desalination, offshore planting, fully passive seawater evaporation, improving light energy utilization rate, seawater evaporation efficiency, preventing seawater backflow, convenient for later maintenance, and realizing fully automatic integration of floating platform change.

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...

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
