Description

Plate type solar distiller

Technical Field

The utility model relates to a distiller, concretely relates to plate-type solar energy distiller.

Background

The solar distiller is a device for purifying sewage, desalting seawater and crystallizing salt water salt by utilizing solar energy. The device heats sewage, seawater or brackish water by utilizing solar radiation heat to vaporize the sewage, the seawater or the brackish water, components such as sludge, salt, silt and the like in the sewage are intercepted in raw water, then the steam is condensed and collected to obtain pure water, and the device can also realize fractionation of multi-component mixed solution. The traditional solar distiller has a simple structure and mainly comprises a water tank filled with raw water and a glass or transparent plastic cover plate covering the water tank. The bottom of the water tank is painted black and filled with raw water to be distilled, and the bottom of the water tank is insulated. The lower edge of a glass or transparent plastic cover plate covered on the water pool is provided with a water collecting ditch which is communicated with an external water collecting vessel. Solar radiation penetrates through the transparent cover plate and is absorbed by the water tank, raw water in the water tank is heated and evaporated to generate steam, the steam rises and is in contact with the cover plate and then condensed into water drops, the water drops flow into the water collecting ditch along the inclined cover plate by means of gravity, and then the water drops flow into the water collector, and pure water can be obtained.

However, although the conventional solar still has the advantages of simple structure, convenient material acquisition, low operating cost and the like, the conventional solar still needs to heat the whole water body in the water tank and then evaporate to generate steam after absorbing illumination energy and converting the illumination energy into heat energy. The specific heat capacity of water is large, so most of heat is wasted in the processes of temperature rise and heat loss to the environment, the photo-thermal utilization rate is low, the heat energy loss is large, the unit water yield is low, and the popularization and the application of the water are greatly limited. In order to improve the performance, researchers in various countries have proposed more effective measures in recent years. For example, a solar heat collector is introduced to improve the light-heat conversion efficiency, a condenser is introduced to improve the temperature of an evaporation water body, and a multi-effect distiller is introduced to reuse latent heat. These methods do increase the water yield per unit area of the apparatus to a certain extent, but also cause problems of increased equipment investment per unit yield, difficulty in operating the apparatus, and the like. Furthermore, as the four seasons change, the solar altitude at different days of the same location will vary, and for a distiller with a fixed inclination or horizontal placement, the projected area perpendicular to the incident direction of the sunlight will also vary, and therefore the solar energy received will also vary. And for the area within the return line of south and north on the earth, the problem that the sunlight incidence directions are completely opposite in summer and winter can occur. This will affect the fresh water production of the solar still.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1-3, the plate solar still is divided into two parts, a plate still and a telescoping stand. The plate distiller is cuboid and comprises an upper light-transmitting condensing sheet 1, a lower condensing sheet 2, a fresh water tank 7, a concentrated water tank 4, a light absorbing sheet 3 and a dropper 5. Two sides, the top end and the bottom end of the plate distiller main body frame are fresh water tanks 7, the sections of the fresh water tanks are U-shaped, and concentrated water tanks 4 are arranged in the fresh water tanks 7 at the top end and the bottom end and communicated with the outside through concentrated water pipes 6. Fresh water tanks 7 at the top end and the bottom end of the plate distiller are respectively provided with a fresh water pipe 8 communicated with the outside. The light absorbing sheet 3 is placed in the middle of the plate still, and the top and bottom ends thereof are placed in the concentrated water tank 4, but not in contact therewith. The two sides of the light absorbing sheet 3 are provided with brackets 12 and fixed at the inner side of the fresh water tank 7. Droppers 5 are arranged in the concentrated water tanks 4 at the top end and the bottom end and are communicated with a water inlet pipe 14. The drip tube 5 is provided with a plurality of water nozzles 13. The upper part of the fresh water tank 7 is pasted with a light-transmitting condensing sheet 1, the lower part is pasted with a condensing sheet 2, and a closed cuboid cavity is integrally formed. The telescopic support comprises a plurality of sections of telescopic connecting rods 11, and the telescopic connecting rods 11 are connected through a rotating shaft 9.

The brine injected by the middle water inlet pipe 14 of the utility model comprises but not limited to seawater, brine, underground brackish water, high-salinity wastewater and sewage which can be treated in a distillation mode; the upper transparent condensing sheet 1 can be made of glass and transparent plastic films such as PE, PVC, PC, PET and the like; the lower condensation sheet 2 can be made of glass, plastic films such as PE, PVC, PC, PET and the like, metal plates, metal sheets and the like; the light absorbing sheet 3 can be made of black materials, such as black cotton cloth, black non-woven fabric, black sponge, black foam, black paper materials, black carbon-based materials, such as carbon black, graphene, carbon nanotubes and other growing/spraying/soaking materials, dyeing materials and the like; the fresh water tank 7 is shaped into a water tank structure by closely attaching the upper transparent condensing sheet 1 and the lower condensing sheet 2 except for a U-shaped material, and other rectangular parallelepiped shapes can be adopted.

When the utility model is used, the plate-type distiller is obliquely placed on the bracket towards the solar illumination direction at noon. Saline is injected into the inlet tube 14 at the top of the device. The brine flows through the drip tube 5, out of the water nozzle 13, drips on top of the light absorbing sheet 3 and progressively wets the entire sheet of material. The flow rate of the saline solution supplied into the inlet pipe 14 should be controlled to correspond to the current light intensity. If the illumination is strong, the flow rate should be increased; if the light is weak, the flow rate should be reduced. The sunlight irradiates the light absorbing sheet 3 through the transparent condensing sheet 1, absorbs and converts the sunlight into heat energy, and heats the seawater on the upper surface of the light absorbing sheet 3. The water vapor is condensed on the inner surface of the transparent condensing sheet 1 to obtain distilled water. Because the thickness of the light absorption sheet 3 is smaller, part of heat is conducted to the lower surface of the light absorption sheet 3, so that seawater on the lower surface is evaporated, and water vapor is condensed on the inner surface of the lower condensation sheet 2, and distilled water is obtained. A small amount of water vapor is additionally condensed on the inner surfaces of the fresh water tanks 7 at both sides of the apparatus. The distilled water flows downwards, is gathered into a fresh water tank 7 at the bottom end of the device, and is finally discharged through a fresh water pipe 8. The strong brine which is not evaporated on the surface of the light absorption sheet continuously flows downwards, is collected in a strong water tank 4 at the bottom end of the device and is discharged through a strong water pipe 6. Along with the change of four seasons, if the solar altitude at noon is gradually reduced, the telescopic connecting rod 10 of the device can be adjusted, so that the inclination angle of the device is increased, a larger light inlet amount is obtained, and the fresh water yield of the device is improved. If the incidence direction of the solar light relative to the device at noon is changed from incidence from south to north (or north to south) to incidence from north to south (south to north), the dropper 5, the saline water in the concentrated water tank 4 and the distilled water in the fresh water tank 7 can be emptied, the whole device is turned over and placed, the inclined surface of the plate distiller faces the sun at noon again, the operation can be recovered, and a larger light inlet amount can be obtained.
