Abstract:
At present, the process of transforming seawater into salt employs a range of diverse methods and techniques. Researchers have introduced an approach aimed at cost reduction in the separation of water and salt from seawater, leveraging contemporary technologies. The primary goal of this investigation is to examine the design and implementation of an automated control system for separating salt from seawater, grounded in the principles of thermoelectricity coupled with ultrasonic technology. Data collection by the researchers unfolded in four main phases. Initially, the complete structure and equipment are assembled. Next, software programs are written to gather data from various sensors. The subsequent step involved data analysis in order to compare experimental results. Finally, the researchers computed the efficiency percentage of salt production and summarized their findings. Key components of this process include the ultrasonic vibration generator, which generates micron-sized water droplets through high-frequency vibrations on the water surface, resulting in smaller mist particles measuring less than 5 microns. Simultaneously, the thermoelectric component is responsible for producing salt by heating the mist containing salt impurities, while the cold side condenses the steam from the hot side back into water. In experiments conducted with water layer thicknesses of 3 cm, 4 cm, and 5 cm, it was observed that the volume of lost water and the temperature of the hot side were similar. However, the particle size of the mist varied, impacting the efficiency of salt production. Consequently, the 5 cm water layer exhibited the highest temperature on the hot side, leading to the greatest effectiveness in salt water evaporation.
