Ships in the ocean (especially ships and ships on ocean routes), fresh water is an indispensable and precious resource. Once water is scarce, it will seriously threaten the safety of ships and crews. However, because of the limited space, the designed water capacity of the ship is also limited. For example, the designed capacity of the 10,000-ton freighter is generally about 350 tons to 550 tons. Therefore, the use of freshwater for ships is an important factor affecting the life quality of the crew and the operational efficiency of the ship’s voyage. Ships are navigating at sea, and seawater is within easy reach. Solving seawater desalination by ship freshwater is undoubtedly an effective and convenient way. The ship comes with a seawater desalination device. The freshwater needed by the whole ship needs only a small amount of cabin capacity. Can be prepared, while increasing the operating tonnage of the ship.
At present, desalination methods used in some ships mainly include distillation and reverse osmosis. Distillation seawater desalination plant works by heating seawater, allowing it to evaporate, and then condensing the steam into fresh water. It is characterized by its ability to be applied even in highly polluted, highly biologically active seawater environments. The reverse osmosis seawater desalination unit utilizes the principle of reverse osmosis for seawater desalination, and the reverse osmosis membrane is a critical component. Under high pressure, the water in the seawater passes through the reverse osmosis membrane and enters the low pressure side (freshwater side). The Other components of seawater are blocked on the side of the concentrated water side of the reverse osmosis membrane and are discharged together with the brine to achieve separation. purpose.
In recent years, due to the high cost and high operating cost of the seawater desalination plant by distillation, the reverse osmosis seawater desalination unit, with advances in membrane science and technology, has drastically reduced the cost of equipment and operating costs, and its application prospects on ships have become more widespread. The core components of the marine reverse osmosis desalination plant produced by Zhuhai Fangfang Seawater Treatment Equipment Co., Ltd. are supported by foreign products. The seawater desalination process and equipment operating parameters have been optimized by the computer to achieve the advanced level in the seawater desalination equipment industry.
