Abstract
A practical experiment was carried out on the performance of solar water distillery using the push of the nozzle in the city of Suez from June to July 2016, Suez Governorate, Egypt, 29.97 ° North 32.53 ° East 11 meters up to sea level. The experiment consists of three parts; saline cycle, air cycle, and humidification-dehumidification unit. The saline water (1 kilogram of seawater is equal to 35 parts of salt dissolved in 1000 parts of seawater) was heated by using the evacuated tube solar collector has an area 3 m2 and an inclination angle of 27°. The humidifier section includes four horizontal nozzles where the diameters were changed according to working conditions. There are three holes in each nozzle where it was punctured at an angle 120° apart. There are two condensers in this system; slant surface with an angle 5° to horizontal and the later one is a coil with a sprinkler. Wire mesh in the humidification side was used to increase evaporation of saline. The effects of nozzle diameter, saline flow rate, hot air stream, and existence of saline in the bottom of the humidifier were monitored. The results show that; The rate of productivity increases with the existence of saline in the base of the humidifier and a wire mesh. Diameter 1 mm is the best diameter for increasing productivity. The productivity increases with the increased flow rate of hot saline water. In this case, condensation using the coil and water spray is less successful than other condensation methods. The higher the temperature of the air the greater the evaporation rate and the less speed of the air. The water productivity is 3.2 Per day from 9.0 am to 3.0 pm. The cost per liter is (0.04 $/L) at the high production (1.76 kg/hr) and the efficiency is 27.7% in the same production.
