The world's largest air purifier has been installed outside the Summer Davos venue.

能把雾霾做成戒指，最大号空气净化器现在大连。

Dutch designer Daan Roosegaarde, the inventor, has brought the device while attending the Summer Davos as a youth delegate.

荷兰籍艺术家兼设计师丹 · 罗斯加德，带着他的作品来大连参加达沃斯了。

The seven-meter-tall Smog Free Tower is currently the world's largest air purifier.

7米高的雾霾净化塔是世界上最大的空气净化器，它通过产生洁净空气为市民提供免费的清新空气体验。

It is designed to suck in 75 percent of pollutants and clean 30,000 cubic meters of air per hour, and consumes very little power.

雾霾净化塔在一天半的时间内，就能将一个正规足球场内的空气净化干净；

它的耗电量很低，仅仅是一台普通空调的耗电量，十分环保。

The pollutants collected from the air purifier are made into diamond rings that cost €5 each. Each ring contains the pollutant that was sucked in from around 1000 m3 of air.

而吸霾塔还有一个神奇的功能，对外部吸进来的有害粒子，施加足够大的压力，最终转化成“钻石”，制成戒指。佩戴这枚戒指，代表着有1000立方米的空气得到净化，而且价值5欧元，还不贵！好想有一枚...

In the future, Daan Roosegaarde will also bring his designed the air purifiers to other cities in China. We hope that in the near future, this device will bring us pure and healthy air.

未来，丹 · 罗斯加德还会带着他设计的空气净化器在中国其他城市展出，希望能在不久的将来看到它的应用，为我们带来纯净的空气。
