Referring to fig. 1-3, a solar evaporation device based on water wave vibration comprises a condensation collecting chamber 1 floating on the water surface, a seawater storage chamber 2 arranged in the condensation collecting chamber 1, and a solar evaporator 3 arranged in the seawater storage chamber 2, wherein a water absorbing body 4 for guiding seawater into the seawater storage chamber 2 is further arranged in the seawater storage chamber 2, a swing fan blade 5 capable of swinging along with the seawater is further arranged right above the solar evaporator 3 in the condensation collecting chamber 1, and steam generated by evaporation of the solar evaporator 3 is condensed and collected on the side wall of the condensation collecting chamber 1 under the fanning of the swing fan blade 5.
The working principle of the utility model is as follows: sunlight is injected from the condensation collecting chamber 1, irradiates on a solar photo-thermal conversion layer on the solar evaporator 3, heats the solar photo-thermal conversion layer, evaporates seawater in the seawater storage chamber 2, continuously conveys the seawater to the seawater storage chamber 2 through capillary action by the water absorber 4, swings the fan blades 5 along with the seawater to generate disturbance on steam, vertically ascends steam fans to two sides of the condensation collecting chamber 1, enables the vertically ascended steam fans to be selectively condensed on the side face of the condensation collecting chamber 1, flows to the bottom of the condensation collecting chamber 1 along the side wall to be collected, and avoids water drops formed after water vapor condensation from dripping on the solar evaporator 3 again, so that evaporation effect is ensured.
Wherein the condensation-collection chamber 1 is provided transparent in its entirety or on top, so that sunlight can be irradiated onto the solar evaporator 3 through the condensation-collection chamber 1. In addition, in order to prevent the steam from overflowing, the evaporation efficiency is affected, and the condensation collection chamber 1 is hermetically arranged. For facilitating the installation of the internal components, the condensation collection chamber 1 is surrounded by a top cover and a bottom plate which are detachably connected.
It will be appreciated that in practical designs, the solar evaporator 3 comprises a porous substrate and a solar photo-thermal conversion layer disposed on the porous substrate, the porous substrate may be melamine sponge, which on the one hand provides a large number of branched micro-channels and specific surface areas for water storage, treatment and evaporation due to its porous structure, thus ensuring that the photo-thermal conversion material has excellent wettability and high hydrophilicity, facilitating sufficient contact of water with the heat absorbing surface and efficient evaporation. On the other hand, compared with other materials, the melamine sponge has the advantages of low cost, extremely low heat conductivity coefficient, repeated replacement and use and the like, and has great application advantages. Of course, other porous materials such as copper foam may be used for the porous substrate.
The solar photo-thermal conversion layer can adopt a PPy/CNT composite material which is a black material, so that on one hand, the water absorption performance and the solar energy absorption efficiency can be improved, on the other hand, the impurity ion concentration in water can be reduced, and the cleanliness of evaporated water can be ensured. Of course, the solar light-heat conversion layer can also be made of other light-heat conversion materials.
It should be explained that, in order to improve the evaporation efficiency, the porous substrate may be designed in a frustum shape, so that the material may be ensured to have a large specific surface area, and absorb sunlight to the greatest extent. In addition, a plurality of rib-shaped grooves can be designed on the surface of the solar photo-thermal conversion layer at equal intervals in parallel so as to increase the light absorption area.
Specifically, one end of the water absorber 4 is connected with the porous matrix, the other end of the water absorber 4 penetrates out of the bottom of the condensation collection chamber 1 and is immersed in seawater, the water absorber 4 can be made of the same material as the porous matrix, and in actual design, the porous matrix and the water absorber 4 are formed by adopting an integrated process, so that the aim of reducing cost is achieved.
In practical application, the condensation collecting chamber 1 is made of acrylic glass, and of course, other transparent materials can be adopted, the inner wall of the condensation collecting chamber 1 is a corrugated surface, and the existence of the corrugated surface effectively strengthens the in-film disturbance, so that the condensation heat exchange coefficient can be improved. The concrete principle is that the wave crest at the corrugated surface can thin the condensate film at two sides of the corrugated surface under the action of the surface tension of water, so that the fluid disturbance is enhanced, the boundary layer is destroyed, the heat conduction resistance is reduced, and the heat transfer is effectively enhanced; meanwhile, the trough of the corrugated surface can accelerate the aggregation of condensate, so that the condensate film is easily transformed into turbulence so as to be separated from the heat transfer surface, and further, the condensate is accelerated to be discharged, thereby accelerating the condensation of water vapor and achieving the effects of efficient condensation and collection.
In order to ensure that the condensation collection chamber 1 can float on the water surface, a foam floating plate 6 is movably sleeved at the bottom of the condensation collection chamber 1, the foam floating plate 6 floats on the seawater, on one hand, the foam floating plate can float on the seawater liquid level, the follow-up swing of the swing fan blade 5 is facilitated, on the other hand, the seawater liquid level can be covered, the seawater is isolated, other volatile substances in the seawater are effectively prevented from reaching the purified water after condensation, and the cleanliness of the purified water is ensured.
Referring to fig. 1 and 2, in some embodiments, a fresh water drainage tube 7 for guiding out condensed liquid drops is further provided on the condensation collection chamber 1, a switch or a direct connection to a purified water collector may be provided on the fresh water drainage tube 7, and the fresh water drainage tube 7 is used for discharging a certain amount of collected purified water.
Referring to fig. 1 and 2, in some embodiments, a flexible supporting swing arm 8 is vertically and fixedly installed in a condensation collecting chamber 1, one end of a swing blade 5 is fixedly connected with the top of the flexible supporting swing arm 8, the flexible supporting swing arm 8 can ensure to support the swing blade 5 on one hand, and has a certain flexible deformation capacity on the other hand, under the action of seawater surge, the flexible supporting swing arm 8 swings under the action of inertia, and then drives the swing blade 5 to swing horizontally, steam is driven to move towards the side wall of the condensation collecting chamber 1, the flexible supporting swing arm 8 and the swing blade 5 are combined to form an L-shaped cantilever beam, the L cantilever beam is made of polyester material, the bottom is fixed on a clamp, and the top is slightly higher than melamine sponge.
Specifically, the flexible supporting swing arm 8 is clamped and fixed on the inner bottom surface of the condensation collecting chamber 1 through the clamp 9, in order to increase response efficiency and improve swing amplitude, the counterweight 10 can be further added at the lower end of the flexible supporting swing arm 8, in practical design, the L-shaped cantilever beam can ensure swing with a certain frequency while the device floats in sea water, the angular displacement of the L-shaped cantilever beam can be approximately a sine function phi (t) =asin (2pi ft), wherein A is amplitude, f is frequency, and the distribution characteristics of vapor inside the device can be changed through regular vibration of the cantilever beam on water wave, so that condensation of the vapor at the top is greatly weakened, condensation is ensured to be mainly concentrated on the side surface of the condensation water tank, continuous direct irradiation of sunlight is facilitated, and evaporation and condensation effects of the device can be improved.
