簡易海水淡化器


海水是地球上最豐富的水資源,許多人一直努力研究,希望讓覆蓋地球表面 70% 的海水可以源源不絕變成淡水使用。

The sea is the most abundant water resources on Earth, many people have been trying to study, hope to cover 70 percent of the Earth's surface sea water can be an endless supply become freshwater use.
2008 年工研院 U19 創意競賽中,明倫高中畢業生陳泊翌、陳崇文、杜佳蓉、莊沛霖、鄭奕彰和潘貫佑設計出一個直徑約 30 公分的飛碟造型海水淡化器,只要將它置於海面上,即可使海水淡化而得到清水。這項設計於該競賽中獲得「最具想像力獎佳作」與「評審團特別獎」,是相當實用的發明。
The ITRI 2008 U19 creative contest, Ming Lun High school, Teenager Chen Chongwen, Teenager Du Jiarong, Zhuangpei Lin, Teenager Yi-Chang Cheng and Teenager Pan consistently woo design with a 30 cm diameter of the flying UFO shape desalination, just put it on the sea, ie, enable desalination of water. The design of the race "the most imaginative Award masterpiece" and "Special Jury Award" is a very useful invention.
陳泊翌表示,構思海水淡化器的起因是看到澎湖鬧水荒的新聞。一開始他們想的解決方式很直接,只要取兩個桶子,之間以管子相連,其中一個桶子裝海水,當海水在太陽下蒸發,水蒸氣碰到管子凝結成水滴後,再設法使其沿管子滴進空桶,就可收集使用。不過此法收集淡水的速度極且收集到的淡水會再度蒸發,毫無實用價值。後來,陳泊翌無意間看到大同電鍋的水蒸氣遇鍋蓋凝結成水滴後,水滴會順著蓋子往下滑落,啟發他們設計另一種具更高效率的海水淡化器。他們從十元商店買了兩個大小一樣的不鏽鋼圓形鍋子,其中一個當蓋子,另一個當做淡水收集槽,蓋子與收集槽之間以隔熱板分隔,隔熱板上鑽洞做導流孔。
Teeager Chen's idea of ​​desalination is drying out the news to see Penghu. The beginning, they want the solution is very straightforward, as long as two buckets to take to a tube connected to a bucket loaded sea water. Whensea water evaporates in the sun, water vapor encountered the tube condenses into water droplets, and then try to make drop along the tube into the empty bucket can collect used. However, this fresh-water collecting meth is very slow, although after trying to replace the pipe material, such as into a higher thermal conductivity of brass, but can improve the desalination rate is limited, and to collect fresh water will be re-evaporation, there is no practical value.

另拿較小的不鏽鋼鍋裝海水,置於隔熱板上,最後蓋上鍋蓋,簡易版的海水淡化器即組裝完成。接著,將海水淡化器放在慢,之後雖然嘗試更換管子材質,如改成熱傳導較高的銅管,但所能提高的淡化速率有限,而海面上,利用太陽熱輻射,使海水升溫蒸發。水蒸氣遇鍋蓋凝結成水珠後,會順著蓋子滴至隔熱板,再從導流孔進入收集槽。

Later, Chen parked next inadvertently see the case lid of Tatung electric pot of water vapor condenses into droplets, water droplets along the lid fall down, to inspire them to design another more efficient desalination. From "1 Dollar Only" store, Chen bought two pieces of the same size circular stainless steel pots. One when the lid, and the other as the separated insulation panels between the freshwater collection tank. Lid with a collection trough, insulation board drill holes diversion holes. Take another small stainless steel pot installed sea water, placed in the insulation panel, and finally put the lid, and a simplified version of desalination is assembled. Then, the desalination device on the sea, use the solar heat to radiate, so the sea water vapors. After the water vapor case lid to condense into water droplets along the lid drops to insulation board, and then from the diversion hole into the collection trough.

陳泊翌表示,此設計於 8 小時內可蒸發數百毫升的海水,當中的隔熱板扮演相當重要的角色,因為它使得隔板上、下層的溫差高達 60℃ 左右,上層約 86℃,下層為 26℃(收集槽浸泡在 24℃ 的海水中)。也就是說,上層的熱氣不容易因熱傳導與下層冷空氣混合而降溫,可長時間保持在高溫的蒸發環境,而下層的淡化水也不易再度蒸發。
Teenager Chen shows how to evaporate hundreds of milliliters of water within 8 hours. The insulation board plays a significant partition differing up to 60 ℃, between the upper to be 86 ° C and the lower to be 26 ° C (a collection trough immersion in sea water of 24 ° C). In other words, the top of the heat is not easy due to heat conduction and the lower cold air mixing and cooling can be a long time remained at a high temperature evaporation environment, while the lower layer of desalinated water is not easy to re-evaporation.

我認為空氣壓縮後膨脹變冷也是一個重要因素.
