[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0026] Embodiments of the present utility model:

[0027] like Figure 1-4 As shown, in the distillation device of this embodiment, a floating seat 1 is provided. The floating seat 1 is made of foam material. A water collecting tank 11 is provided in the floating seat 1, and a through hole 12 which is transparent from top to bottom is provided in the center of the floating seat 1. A drainage hole 111 is provided in the water collecting tank 11, and the drainage hole 111 is connected to a collecting bottle 15; wherein, a glass drainage pipe 13 is fixed in the drainage hole 111 by gluing, the drainage pipe 13 is connected to a rubber hose 14, the rubber hose 14 is connected to the collecting bottle 15, and a water stop clamp 141 is provided on the rubber hose 14.

[0028] A condensation hood 3 is fixedly installed in the water collecting tank 11 by gluing, wherein a light-transmitting hood body 31 is arranged in the condensation hood 3, a connecting edge 32 is arranged on the outer periphery below the light-transmitting hood body 31, and the condensation hood 3 is sealed and fixed by bonding with the connecting edge 32, and the drainage hole 111 is located inside the condensation hood 3 and does not interfere with the connecting edge 32 in space; and a pull ring 311 is arranged above the light-transmitting hood body 31, and a guide groove 312 is arranged on the inner periphery of the light-transmitting hood body 31.

[0029] A photothermal evaporator 2 is placed in the through hole 12, and the photothermal evaporator 2 includes a conical support 21 made of foam material and a photothermal film 22 wrapped on the conical support 21, wherein a cavity 211 is arranged inside the conical support 21, and an outer edge 221 extending from the bottom of the photothermal film 22 to the bottom of the conical support 21 and forming a certain length.

[0030] The principle of this utility model is:

[0031] When assembling the utility model, the condensation cover 3 and the drain pipe 13 are first connected and fixed on the floating seat 1 by gluing. During the process, the stability and sealing of the connection are ensured, and the experimental operation can be carried out at this time.

[0032] In the utility model, the diameter of the conical support 21 is 10 to 15 cm, and the horizontal inclination angle of the conical surface is 45°; the diameter of the floating seat 1 is 20 to 30 cm, and the inclination angle of the conical surface of the light-transmitting cover body 31 can be reasonably selected according to the latitude of the time; the laboratory prepares seawater and places it in an outdoor water reservoir or bucket, at this time, the conical support 21 is placed in the seawater, and the photothermal film 22 that needs to be explored is selected and coated on the conical support 21. The photothermal film 22 can be tightly attached to the conical support 21 when it encounters water, and the boundaries of the photothermal film 22 can be stacked; then, the floating seat 1 is connected to the collecting bottle 15, and the condensation cover 3 connected to the floating seat 1 is placed on the photothermal evaporator 2, and the photothermal evaporator 2 is placed inside the condensation cover 3 through the through hole 12 on the floating seat 1.

[0033] Therefore, the evaporation performance of the photothermal film 22 can be experimentally investigated. Under the condition of light, sunlight passes through the light-transmitting cover body 31 and shines on the photothermal film 22. During the process, due to the capillary water absorption effect of the photothermal film 22, the seawater can be lifted capillaryally, and then it evaporates continuously on the conical support 21. The water vapor generated by evaporation rises and condenses on the inner side of the light-transmitting cover body 31, and then flows into the water collecting tank 11 through the guide groove 312, and then is discharged through the drain pipe 13. By collecting the amount of pure water obtained from different photothermal films 22 under the same sunlight conditions, the evaporation efficiency of the photothermal film 22 can be compared and judged (when collecting pure water, the condensation cover 3 can be lifted up to completely collect the generated pure water, and the water stop clamp 141 can be used to replace the conical bottle).

[0034] The utility model is easy to use and clean (metal salt) in experimental research, which brings convenience to experimental research, and different photothermal films 22 can be used or prepared to find a photothermal film 22 with higher evaporation efficiency, which is of great significance to the research on seawater desalination and sewage purification. For example, a polypyrrole fiber membrane is obtained through research, and a super-hydrophilic fiber membrane (CF) is immersed in an ultrasonically uniform pyrrole (Py) solution. The Py monomer is attached to the surface and inner layer of the membrane fiber through the hydrogen bond between the -N of the Py ring and the -OH of the cellulose. Subsequently, an oxidant FeCl3·6H2O is added to the above solution to polymerize Py on the fiber, thereby obtaining a polypyrrole fiber membrane (PCF). The utility model explores its performance and finds that under winter solar radiation, it reaches 5.3L / m for 7h. 2 The condensed water collection rate is increased by 2.5 times compared with the research under plane conditions. On the one hand, it can more accurately express the evaporation performance of the photothermal film, and on the other hand, it also has positive significance for the research on seawater desalination.
