Practical Investigation of Some Characteristics of the Solar Distillation System for Solar Water Desalination

摘要

This paper deals with a practical investigation of some of the physical properties of a solar distiller for desalination of water using solar energy, as a solar distiller was designed equipped with a tank of sea water to feed it, and the device was placed in a horizontal plane by a base, where it was found practically through previous studies that the best direction for the distiller. The solar distillation is in the southeast and the solar distillation is fixed in a place exposed to solar radiation during the hours of solar brightness, and this place is located in College of Education - Janzour, where the entry and exit temperatures of the solar distillery were recorded from the hour 09:00 AM to 14:00 PM for each day for a period of five months The study period started from the month of November, 2019 to March, 2020. The productivity of the solar distiller and the volume of water obtained per day, as well as the air temperature for each day and for each hour, were calculated. The overall efficiency of the solar distillation was calculated and the results obtained were recorded in tables where the average months were taken with time, and the solar radiation data were taken from the period November, 2019 to March, 2020 from the Research Center for Renewable Energy and Water Desalination - Tajoura The results were discussed according to the previously defined climatic and weather conditions for the same period with the graphical representation and the inclusion of the values shown in numbers for each month, as the efficiency of the solar distillation ranges in the range of (6%) and this efficiency is considered reasonable with the efficiency of other solar distillates of the horizontal type, as well as the results are determined. The depth of the water inside the distillation basin has a large impact on productivity as the productivity increases as the depth of the water inside the distillation basin decreases, directly with the increase in the evaporation rate.
