船舶用太阳能取水管性能测试实验研究

为提供一种船用淡水问题的潜在解决方案,本实验利用13X、3A和5A型等3种不同沸石分子筛吸附剂吸附空气中的水蒸气,并利用太阳能获取液态淡水供船舶使用。通过对制作的太阳能取水管(solar watering tube,SWT)性能测试可得出以下结论:在全日辐射量为20.1 MJ/m2和16.7 MJ/m2时,13X、3A和5A型吸附剂吸附床温度最高分别为178.2℃、180.1℃和217.7℃,均达到脱附温度要求。在自然对流风冷式冷凝器中,13X、3A和5A型SWT最高冷凝温度分别为27.8℃、33.2℃和31.9℃,均满足冷凝要求;3种吸附剂制备的SWT利用太阳能吸附法可分别从空气中取淡水57.8 g、39.2 g和44.0 g,有潜在的解决船用淡水的前景。

Experimental study of performance test for solar watering tube used in ships

In order to provide a potential solution to the problem of ship fresh water,this experiment uses three different zeolite adsorbents,13X,3A and 5A,to absorb water vapor in the air,and uses solar energy to obtain liquid fresh water for ship use.These following conclusions can be drawn by testing the performance of the solar watering tube(SWT):under the conditions of the full-day radiation being 20.1 MJ/m2 and 16.7 MJ/m2,the maximum temperatures of the adsorption beds of 13X,3A and 5A adsorbents are 178.2℃,180.1℃and 217.7℃,respectively,which meet the desorption temperature requirements.In the natural convection air-cooled condenser,the highest condensation temperatures of 13X,3A and 5A SWTs are 27.8℃,33.2℃and 31.9℃,respectively,which meet the condensation requirements;fresh water 57.8 g,39.2 g and 44.0 g can be obtained from air by SWTs with three different adsorbents,which has the potential to solve the problem of ship fresh water.
