雾霾净化塔，中国

设计公司：罗斯加德工作室/ Studio Roosegaarde（荷兰）

“减霾计划”是一个旨在修复环境和减低空气污染的项目。计划将一项被实证有效、且取得专利的正离子技术，应用于深受空气污染影响的地区。项目其中一件惹人注目的设计 — “雾霾净化塔”，以试验性质放置于北京和天津。从远处眺望，雾霾净化塔就像在草坪上耸立的烟囱，但它的功能与排放污染物的烟囱却恰好相反。这座塔从顶部收集受污染的空气，塔内的扇叶在运转期间会截留空气中的雾霾粒子，从而起到过滤空气的效果。雾霾净化塔每小时能净化30 000 立方米的空气，虽然功效如此强劲，但由于以风能推动，其能源消耗量其实只与一般家庭电器相若。经净化后的空气从塔的下层释出。在小区层面，人们亲身体验后亦认为，雾霾净化塔座落的公园，其空气比该巿其他地区清新、干净得多。雾霾净化塔是设计师罗斯加德（Roosegaarde）一项名为“未来景观”大型计划的其中一环。他希望兴建多座雾霾净化塔，从而改善城巿层面的空气质量。除此之外，雾霾净化塔运作过程中所截留的雾霾粒子，更被加工制成“雾霾戒指”。一枚雾霾戒指代表净化了1 000 立方米空气，它不仅见证人们为了保护环境所作出的集体努力，更提醒我们爱惜自然的责任。

The Smog Free Project is an environmental rehabilitation and air pollution reduction strategy that deploys proven and patented positive ionization technology in places where it is needed the most.Experimental towers were erected in Beijing and Tianjin. Although from a distance, the smog free tower looks like a stand-alone chimney that rises up from the lawn, it actually does the opposite of what a chimney does. Instead of emitting polluting air to the atmosphere at the top opening, the tower draws polluted air in from the top, and filter the air through the blades that collect the smog particles. Each tower cleans 30 000 cubic metres of air per hour, and mainly runs on wind energy so its level of electricity consumption is comparable to a household appliance.The treated air is then released from the bottom part of the tower. At the local level, the park users experience cleaner air than other parts of the city. As part of his larger body of works, called “Landscape of the Future”,Roosegaarde hopes that a multitude of towers may make a diあerence in air quality at the municipal level.But that is not all. The smog dust collected by the towers is processed and made into the stone of a ring. Marketed as the “Smog Free Ring”, the piece of jewellery symbolises the smog collected from 1 000 cubic metre of polluted city air. Akin to pitching in to fund an environmental solution, the ring is a testament to the collective eあort to clean up our planet, and an everyday reminder of what everyone can do to help.
