Description

Plate type solar distiller with light absorbing material convenient to replace

Technical Field

The utility model relates to a distiller, in particular to a plate type solar distiller with light absorption materials convenient to replace.

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. Chinese patent 201922168579.3 discloses a plate solar still, but the device's water supply mode is for a plurality of burettes drip irrigation formula water supply, and the water supply is uncontrollable, when weather changes, can't reach ideal evaporation effect, and drip irrigation formula water supply brings another problem is that the extinction piece can't reach an even moist state, influences the product water effect of device. And the light absorbing sheet bracket is fixed on the two sides of the device main body frame through the support legs and can not be taken out, so when the light absorbing sheet is damaged or the performance of the light absorbing sheet is reduced due to surface scaling after long-time use, the whole device is required to be completely disassembled when the light absorbing sheet is required to be replaced, and the operation is not easy.

Detailed Description

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

As shown in fig. 1-4, a panel-type solar still that facilitates replacement of light absorbing materials includes a panel-type solar still and a support bracket. The plate distiller is cuboid and comprises an upper transparent condensing sheet 1, a lower condensing sheet 2, a fresh water tank 5, a concentrated water tank 6, a light absorption sheet 4, a flexible water absorption material 15 and a water supply pipe 9. The two sides and the bottom end of the plate distiller main body frame are fresh water tanks 5, the sections of the fresh water tanks are U-shaped, and concentrated water tanks 6 are arranged in the fresh water tanks 5 at the bottom ends and are communicated with the outside through concentrated water pipes 7. A fresh water tank 5 at the bottom end of the plate distiller is provided with a fresh water pipe 8 communicated with the outside. The light absorbing sheet 4 is placed in the middle of the plate still, and the bottom end of the light absorbing sheet is placed in the concentrated water tank 6 but is not contacted with the concentrated water tank. Two sides of the light absorbing sheet 4 are provided with support legs which are placed on a slide rail 16 at the inner side of the fresh water tank 5. The water supply pipe 9 at the top end is inserted with a flexible water absorbing material 15 to be connected with the light absorbing sheet 4, the flexible water absorbing material 15 completely covers the top end of the light absorbing sheet 4, the water supply pipe is communicated with the concentrated water tank 14 through a water inlet pipe 13 and a water return pipe 12 to form circulation, a water pump is arranged in the concentrated water tank, and a solar cell panel is connected with the water pump to provide power. The upper part of the fresh water tank 5 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.

Brine injected into the concentrate tank 14 in the present invention; the upper transparent condensing sheet 1 and the lower condensing sheet 2 can be made of glass and transparent plastic films such as PE, PVC, PC, PET and the like; the light absorbing sheet 4 can be made of black materials, such as black cotton cloth, black non-woven fabric, black sponge, black foam, black paper materials, and black carbon-based materials, such as carbon black, graphene, carbon nanotubes, and other growing/spraying/soaking and dyeing materials; the fresh water tank 5 is closely attached to the upper transparent condensing sheet 1 and the lower condensing sheet 2 to form a closed space, so that a water tank structure is formed, and a cuboid section can be adopted.

When the plate distiller is used, the plate distiller faces the sun illumination direction at noon and is obliquely placed on the bracket. Brine is injected into a concentrated water tank of the device. The saline water is pumped into the water supply pipe by a water pump 11 powered by a solar panel 10, and a flexible water absorption material 15 in the water supply pipe 9 is connected with the top of the light absorption sheet 4 and wets the whole sheet of material gradually. Because the whole device is powered by the solar water pump, the water supply amount of the whole device is automatically adjusted according to the illumination intensity of sunlight.

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 4 is smaller, part of heat is conducted to the lower surface of the light absorption sheet 4, 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 5 at both sides of the apparatus. The distilled water flows downwards, converges into the fresh water tank 5 at the bottom end of the device, and is finally discharged through the fresh water pipe 8.
