Detailed description of the invention
Fig. 1 is that the overall structure based on graphene/porous carbon/carbon-copper composite material desalination plant in the present embodiment is shown
It is intended to.1. taper cover board, 2. cavity, 3. composite bottom board, 4. catchment recess, 5. water receiver in figure.
Specific embodiment
In order to allow features described above and advantage of the invention to be more readily understood, below in conjunction with attached drawing, 1 couple of present invention is done furtherly
It is bright.
(1) whole device is suspended in seawater liquid to be processed, and device bottom plate fully absorbs seawater to be processed, works as solar irradiation
Penetrate top 1. taper cover board when, fraction solar radiation is absorbed or is reflected back by cover board, most of to be incident upon dress through cover board
Bottom set portion based on three-dimensional grapheme/porous carbon/carbon-copper composite material photothermal conversion 3. composite bottom board, due to sunlight carry it is big
Energy absorbs and is converted into thermal energy by device bottom plate, heats seawater to be distilled in 2. cavity, and seawater is heated to be evaporated to water steaming
Gas convection current together with air in 2. cavity moves bottom-up.
(2) since 1. the solar energy of taper cover board absorption is less at the top of device and directly radiates to surrounding, so temperature
Lower than the temperature of seawater in 2. cavity, vapor cover board to the cold and in its sweating water pearl flows into along inclination wooden partition and is located at
1. in taper cover board and the 2. 4. catchment recess of four wall joint of cavity, the water purification that collects is from 4. one aperture stream of catchment recess end
Out after reaction chamber, it is stand-by that storage is exported into the 5. water receiver of the other side by rubber hose.The pollutants such as salinity, bacterium in water
The high fresh water of degree of purification will not be obtained with water evaporation.
(3) the porous 3. composite bottom board porosity of three-dimensional structure is high, and aperture is small (about 5mm), can be good at reducing position
The forced convertion caused by the seawater fluctuation of lower layer influences to reduce heat loss.When bottom plate upper ocean water be constantly evaporated it is cold
It is solidifying, it is acted on by vapour pressure effect and atmospheric pressure, bottom plate lower layer seawater can be automatically replenished and be formed from bottom to top in hole
Slowly movement, top evaporation of seawater rate is faster, and the absorbability of lower section seawater is stronger.Meanwhile the heat that composite bottom board is absorbed
Amount is to be conducted from top to down, forms the thermally conductive phenomenon of a gradient in material internal, forms reverse heat with upward seawater
Exchange, heating seawater is without making heat loss to the full extent.It is transferred heat in the short time and fills in its hole and be located at
The seawater on bottom plate upper layer improves the heating evaporation efficiency of seawater.
