pyramid solar still
Pyramid solar still is an innovative idea and design for the solar still that have higher productivity and many more other benefits over conventional solar still. Different versions of a still are used to desalinate seawater in desert survival kits and for home water Purification.

Experimental measurements were recorded and.
. Secure the edges of the plastic sheet with rocks and dirt to prevent the escape of moisture. 3Investigation of thermal performance of the square pyramid. Performance of still was evaluated for various depths of basin water.
The theoretical and experimental analysis of square pyramid solar still was performed. Compared analytically the single slope solar still and pyramid solar still. The experimental setup mainly consists of an insulated rectangular basin.
The area of the glass cover depends on the tilted angle of the cover on the horizontal as shown in Fig. The pyramid shape solar still PSSS can receive solar input radiation from all four directions. The experiment is analysed with a constant depth without porous material and it has maximum temperature of glass is 60 C at 1 pm in lower surface and the maximum temperature of glass is 66 C at 2 pm in upper surface.
Various wick materials were kept vertically in the solar still for enhancing the yield. Up to 10 cash back A schematic diagram of the square pyramid solar still is shown in Fig. A distillation system was fabricated to achieve this goal a distillation system was fabricated which incorporates square pyramid fiberglass placed on a black-coated Aluminum basin.
To compare and evaluate the triangular and pyramid-shaped solar stills. From the review on research carried out by the various researchers it has been found that pyramid solar still is more efficient. 10 to study about comparative evaluation of two basin type passive solar stills of pyramid shape solar still and rectangular solar still and conclude that more area of basin get more output of yield.
Push down the weight gently until the sides slope to an angle of 45 o. The solar still can have several geometries for example single or double slope spherical prism tabular and pyramid. Performance study of ZnOAl 2 O 3 nanocomposites in escalating the productive yield of pyramid solar still coupled with shallow solar pond using escalated heat transfer coefficient had been analyzed.
Pyramid solar still is one of the outcomes of such a development. They found that both of them have a similar efficiency and productivity but the. Expensive and energy intensive.
Close the tubing end with a knot or tie it closed if used. The productivity of triangular pyramid solar still with and without latent heat storage medium has been experimentally found by RavishankarSathyamurthy. A passive solar still combined with a heat storage system was developed and used for desalination of brackish water.
Thus it is necessary to establish function that describe the relationship which can be. In this paper an attempt is made to study the productivity of pyramid solar still. 13 SIGNIFICANCE OF THE STUDY.
An automatic feedwater system for Solar still. The advantages of seawater desalination are. Performance of triangular pyramid solar still and inferred that the increase in wind speed from 15ms to 3 ms and 45 ms has shown in the increase of productivity by 8 and 15.
The energy from the sun used to distil water is free cost but building the still makes the cost of the distilled rather high water at least for large-scale uses and such as agriculture and flushing away wastes in industry and homes. Solar stills are used in cases where rain piped or well water is impractical such as in remote homes or during power outages. In this work pyramid solar still performance was enhanced by using evacuated tubes external condenser nanoparticles and ultrasonic foggers.
The pyramid solar still has a pyramid cover geometry. The solar radiation which is incident on the black-coated basin heats the water. Solar Distillation is an attractive alternative because of its simple technology non-requirement.
In this research the top layer of conventional pyramid shape solar still CPSSS is covered with airpacked cover and analysed the effect in the modified still after air packed in between the two glasses finally that result is compared with the. 2It consists of a 05 05 m 2 basin liner and four glass covers eastern western southern and northern. Sharshir and others published 4-E analysis of pyramid solar still augmented with external condenser evacuated tubes.
The productivity of condensate water was maximum for 2 cm basin water depth. Place a small rock in the center of the sheet just above the water container. Solar water distillation is a very old technology.
The present paper reviews the development in the field of pyramid solar still as well as the various techniques to improve the performance of still. The performance of single basin square pyramid solar still was experimentally analysed with and without porous materials. Saghi Experimental investigation of the effect of using water and ethanol as working fluid on the performance of pyramid-shaped solar still integrated with heat pipe solar collector Sol.
PDF On Jun 1 2022 Swellam W. Shallow Solar Pond SSP of area 08 m 2 used as additional source of transferring heat to Pyramid Solar Still PSS of area 025 m 2Heat transfer values. Performance of solar still depends on operational design and meteorological parameters.
An early solar still was built in 1872 to supply drinking water to a mining community in Chile Bounds 2012. Although the idea of solar desalination plants is visionary for the future this idea also has some drawbacks. Experimental analysis conclude that pyramid shape solar still increase of 175 compare to single slope solar still.
