Don't be too superstitious haze Tower, experts say the results to find cover site-IT information
Beijing once again lost in fog and haze. Since the beginning of October 18, Beijing particulate concentration continued to rise, up to 19th, at 12 o'clock, heavy pollution has lasted 19 hours, with 6 stations reached the critical level of pollution, and increasing trend. 19th, the municipal meteorological station issued a haze of yellow warning signal again, this is since October, suffered a third round of severe pollution in North China, Beijing Bureau of meteorology fifth heavily polluted yellow warning was issued.
Meanwhile, a fight against smog "war" is quietly under way. By the Netherlands designed by artist Dan·luosijiade titled "Cave of the smog-free" smog tower at the end of September in Beijing, currently in the 798 art district, Chaoyang District, debugging and testing , elective official met with the public.
According to about media reported, the fog haze purification Tower has 7 meters high, is world Shang maximum of air purification device, its using small of green energy and patent of no ozone ion technology, each hours can purification 30,000 cubic metres of air, can capture and collection air in the at least 75% of PM2.5 and PM10 fog haze particles, while to 360 degrees full release fresh air, in Tower of around manufacturing out a ring fresh air regional. Designers also said the collection of smog particles can be compressed into black jewels.
In China, the "Cave of the smog-free" haze haze Tower the governance "artifact" in number. On May 12, 2016, the XI in addition to capping haze Tower project on schedule. Allegedly, the device can be removed by atmospheric PM2.5 in the formation of smog such as NOx, SO2, and key precursors, thus effectively controlling smog formation. In January 2015, there was fog Gun Carriage away haze, Zhengzhou city. Allegedly, the spray mist particles can reach micron level, so as to break down air pollution particles, dust and so on, to alleviate the effects of smog. In addition, Zhejiang University Professor Yu Shaocai also raised "water-jet treatment of haze" approach, saying to the outside on top of the tower and the Tower of atmospheric water, reduce air pollution, curbing serious smog.
"Perhaps is the treatment of haze of despair. "Institute of Tsinghua University, energy innovation on the Internet says He Jijiang, Director of the Research Office of policy development.
Despite the demand for smog control has very urgent, but the "Cave of the smog-free" smog tower still questioned by many experts. According to expert calculations, in the condition of serious pollution, the PM2.5 concentrations of 200 micrograms per cubic meter, which absorb PM2.5 total 30000x200x0.001x0.001x75%=4.5 grams per hour. According to the data, which absorb the amount of smog per hour less than the weight of a teaspoon of salt. The expert joked: "is to find a cover to your site now! ”
"Treating haze ' artifact ' can give it a try, but the symptoms, not the causes, can only play a role in experiments. "He Jijiang said.
别太迷信雾霾净化塔，专家称效果不如找布盖工地 - IT资讯
北京再一次陷入雾霾笼罩之中。自10月18日中午开始，北京市颗粒物浓度出现持续上升，截至19日12时，重度污染已持续19小时，其中6个监测站点达到严重污染级别，且呈加重趋势。19日，北京市气象台再次发布霾黄色预警信号，这是进入10月以来，华北地区遭遇的第三轮重度污染，也是北京气象局第五次发布重污染黄色预警。
与此同时，一场抗击雾霾的“战争”正在悄然展开。由荷兰艺术家丹·罗斯加德设计的名为“无霾之洞”雾霾净化塔已于9月底进京，目前正在朝阳区798艺术区内进行调试和测试，将择期与公众正式见面。
据有关媒体报道，该雾霾净化塔有7米高，是世界上最大的空气净化器，其使用小量的绿色能源和专利的无臭氧离子技术，每小时能够净化3万立方米的空气，可捕捉并收集空气中至少75%的PM2.5和PM10雾霾颗粒，同时以360度全方位释放清新空气，在塔的周围制造出一个环状清新空气区域。设计者还称，收集到的雾霾颗粒可被压缩做成黑色的宝石。
在中国，像“无霾之洞”雾霾净化塔这样的治霾“神器”并不在少数。2016年5月12日，西安市除霾塔项目如期封顶。据称，该装置可以通过去除大气环境中的PM2.5及NOx、SO2等雾霾形成的关键前体物，从而有效控制雾霾形成。2015年1月，郑州市曾出现雾炮车消霾。据称，其喷射的水雾颗粒可以达到微米级，从而分解空气中的污染颗粒物、尘埃等，起到缓解雾霾的作用。此外，浙江大学特聘教授俞绍才也曾提出“喷水治霾”的方法，称在高楼及高塔的顶上向建筑物外大气喷水，能够减少空气污染，遏制严重的雾霾。
“也许是人们对治霾绝望了吧。”清华大学能源互联网创新研究院政策发展研究室主任何继江说。
尽管人们对雾霾防治的需求已经十分迫切，但“无霾之洞”雾霾净化塔的出现仍受到不少专家的质疑。据一位专家计算，在严重污染条件下，PM2.5浓度为200微克每立方米，该塔每小时吸收PM2.5总量为30000×200×0.001×0.001×75%=4.5克。按照该数据，该塔每小时吸收的雾霾量还不到一勺盐的重量。该专家调侃：“还是去找一块布盖一下工地吧！”
“治霾‘神器’可以尝试一下，但治标不治本，只能起到实验的作用。”何继江说。
