Problems solved by technology

These methods are energy-intensive, require high energy delivery, and are too costly for offshore desalination
[0003] A seawater desalination device proposed in patent CN201310602853.8 is composed of several simple parts such as a coagulation clarification tank, a clear water tank, a seawater security filter, and a fine sand filter. The effect of each stage, the desalination efficiency is low, and the energy consumption is high
[0004] The traditional method is to directly heat water by sunlight and use heat convection, which has low efficiency. However, this method uses direct heat conduction with high light-to-heat conversion efficiency to high specific surface area fibers to use heat conduction, and the efficiency has been greatly improved.

Abstract

The invention discloses a seawater desalination device which is mainly composed of a light-pervious heat-insulating cover, a seawater storage tank, a fresh water collection tank, a light-absorbing resin layer, a graphene layer, a heat-conducting silicon wafer, water delivery fiber, a hollow copper pipe with holes in the surface and an internal threaded ring. The light-pervious heat-insulating cover is connected to the fresh water collection tank through a hinge, the graphene layer deposits on the heat-conducting silicon wafer to form a graphene plate, the light-absorbing resin layer is coated on the graphene plate, the graphene plate is fixed in the middle of the seawater storage tank through interference fit, the hollow copper pipe with the holes in the surface is connected with the internal threaded ring through a thread, the internal threaded ring is welded on the light-pervious heat-insulating cover, the water delivery fiber is wound on the hollow copper pipe in an inside-outside alternating manner, and the other end of the fiber is soaked in seawater. The seawater desalination device is simple in structure, seawater can be delivered to an evaporation end by utilizing capillary principles of the high-performance water delivery fiber, and evaporation of water is accelerated by applying high specific surface area of the fiber, so that seawater desalination efficiency can be improved greatly.

Description

technical field [0001] The invention relates to a device which converts sunlight into internal energy to promote seawater evaporation and desalination, and belongs to the field of seawater desalination. Background technique [0002] Water is the source of life and an irreplaceable natural resource for human beings. Seawater desalination is one of the important measures for China to solve the shortage of freshwater resources in coastal areas in the 21st century, and it is also an inevitable choice. At present, seawater desalination technology has formed a new type of industry with broad development prospects, which has played a positive role in promoting social development and the improvement of people's living standards. Desalination is the technology and process of obtaining fresh water from the sea. The more common applications are multi-stage flash distillation, electrodialysis, and reverse osmosis. The above-mentioned methods are energy-intensive, require high energy ...
