目的设计一款便携式液体空气净化器。方法采用滤膜、活性炭吸附层及PP粉溶液等3级净化处理。结果在相同条件下经过滤膜和活性炭吸附层去除烟雾的时间是8 min;经过滤膜、活性炭吸附层和蒸馏水层是6 min;经过滤膜、活性炭吸附层和PP粉溶液去除烟雾的时间是4.5 min。加水层及PP粉溶液去除烟雾的时间分别缩短25%和43.75%。结论在滤膜及固体吸附净化的基础上,增加PP粉溶液后,其净化效果显著提高。另外PP粉溶液还可将还原性有害气体及空气中的细菌等有害物质去除,同时还可根据PP粉溶液的颜色变化判断空气污染的程度,当PP粉溶液的颜色由紫红色变为浅褐色时就应更换。该款净化器体积小、采用低压直流电机安全可靠,携带方便。
Purpose To design a portable liquid air purifier. Methods The membrane, activated carbon adsorption layer and PP powder solution 3 grade purification. Results Under the same conditions, the time for the removal of smoke through the membrane and the activated carbon adsorption layer was 8 min. After filtration, the activated carbon adsorption layer and the distilled water layer were 6 min. The time for removing the smoke through the membrane, activated carbon adsorption layer and PP powder solution was 4.5 min. Adding water and PP powder solution to remove the smoke were reduced by 25% and 43.75% of the time. Conclusion On the basis of filtration and solid adsorption purification, the purification effect of PP powder solution increased significantly after PP powder solution was added. In addition PP powder solution can also reduce harmful gases and airborne bacteria and other harmful substances removed, but also according to the color change of PP powder solution to determine the extent of air pollution, when the color of PP powder solution from purple to light brown Should be replaced. This purifier small size, low voltage DC motor safe and reliable, easy to carry.
