确保室内空气清洁——新的空气污染控制方法

For the Sake of Clean Air

室内空气污染控制有新招

New Ways for Indoor Air Pollution Control

随着我国国民经济的快速发展，大气污染情况日趋严重，雾霾经常笼罩着各个城市，严重影响人们的日常生活。据统计：近年来华南地区出现雾霾的天数占全年的50%左右，华东地区（以上海为代表）占61%，华北地区更是高达75%，空气污染已成为常态化问题。

With the rapid development of national economy， air pollution is becoming more and more serious， and various cities are often shrouded by smog， seriously interfering with people’s daily lives. According to the statistics， in recent years， smog appears in South China for about 50% of the whole year; in East China (represented by Shanghai) the number is 61% while in North China as high as 75%. In conclusion， air pollution has become a pervading problem.

雾霾是由可吸入颗粒物、二氧化硫和氮氧化物组成，其中可吸入颗粒物是最主要的污染物，而PM2.5是可吸入颗粒物中对人体危害最大的成分，由于其直径小于等于2.5微米——相当于东方人头发丝直径的1/35——能够穿透人体的呼吸系统而直接进入肺部深处，引发多种呼吸道疾病。另外，PM2.5极易吸附多环芳烃等有机污染物和重金属，使致癌、致畸、致突变的概率明显升高，从而对人体健康造成重大危害。

Smog is composed of sulfur dioxide， nitrogen oxides， and respirable particulate matter， where in the last one is the main pollutant. And when it comes to the respirable particulate matter， PM2.5 is the most harmful component， because its diameter is less than or equal to 2.5 μm， which is equivalent to 1/35 of an oriental’s hair diameter， and thus can penetrate the human respiratory system directly into the deep of the lungs， causing various respiratory diseases. In addition， PM2.5 is prone to adsorb organic pollutants and heavy metals， like polycyclic aromatic hydrocarbons， significantly raising the carcinogenic， teratogenic， mutagenic rates， and gravely harminghuman body.

2015年大气污染防治法正式出台，举国上下大气控制的各项管理措施和法案相继出台，废气处理以及监督监管机制力度逐级加大，由此将出现废气处理的巨大市场。

Air Pollution Prevention Law was formally passed in 2015， and acts and regulations of air pollution control have also been made across the whole country， increasing efforts to treat waste gas and supervise the process， and thus expanding a huge market of waste gas treatment.

室内空气净化综合处理的新型驻电极静电（SNEP）技术

Novel Electrode Electrostatic Technology （SNEP） for Indoor Air Purification Integrated Processing

SNEP驻电极静电技术，是最先进的室内空气净化系统之一。它是目前市场上鲜有的一款不但能够有效去除室内PM0.5以上颗粒物，还能强力杀灭细菌、病毒，并且无需更换滤芯的节能环保净化产品。

SNEP electrode electrostatic technology is one of the most advanced indoor air purification systems. It can not only effectively remove indoor PM0.5 particles， but also effectively kill bacteria and viruses， with no need to replace the filter.

SNEP驻电极静电技术替代了传统中效过滤器，对实现降低能耗，清洁生产，减少二次污染，具有重要意义。由于驻电极具有高效率、低风阻、低耗电、易清洁、长寿命的优点，并改进了传统的过滤工艺，其意义非常深远，因此，推广应用领域广，市场推广应用的价值将非常巨大。可广泛应用于商场、酒店、会所、医院、办公楼、住宅楼、院校、展览馆、博物馆和体育馆等地方，保障公众健康。该技术是采用新型复合材料，即使用了静电驻极改性材料、抗菌材料，通过EAT等其他专利技术，采用微观的静电集尘通道具有静电凝并特性，细微颗粒物被荷电异性电荷吸引产生凝并作用形成大颗粒被捕集，可捕集细小颗粒物，具有优越的PM2.5净化性能，对于0.3微米的颗粒物亦有很高的捕集效率。安全，无打火、异常放电，不产生臭氧；高效率，最高可达99.9%效率；易清洁，模块化设计，全密闭结构，直接水洗清洁。

Using the electrostatic technology of SNEP electrode to replace the traditional filters has great significance in reducing energy consumption and secondary pollution. It is easy to clean， and because ofits high efficiency， low wind resistance， low power consumption， and long life， it can thus be applied and promoted widely. It can be used in shopping malls， hotels， clubs， hospitals， office buildings， residential buildings， colleges and universities， exhibition halls， museums， stadiums and other places to protect public health. This technology uses a new type of composite material， namely the electrostatic electrode modified material， and antibacterial material. Using other patented technologies like EAT， the micro electrostatic dust collecting channel has electrostatic coagulation characteristics， and the fine particles are charged the opposite charge to form larger particles because of the coagulant effect and then be captured. It can trap very small particles like PM2.5， and it is also highly efficient in collecting 0.3 μm particles. SNEP is safe because there is no fire or ozone， efficient (up to 99.9%)， and easy to clean because of its modular design， fully enclosed structure， and because it can be cleaned directly by water.

滤网及净化技术

Filtering and Purifying Technology

综合了现有主流且成熟的几种净化技术。在确保满足环保高效的前提下，对主动式和被动式净化的多种技术进行了长时间的研究和测试，最终选择了被动式的净化方式作为我们深化方向之一。采用一种“静电驻极的HEPA过滤网+活化处理的活性炭+无毒无扩散剂的抑菌层+类似多层织网结构的粗滤”等配置的复合滤网技术来进行深耕和研发，为此豹米科技联合美国3M公司共同开发了一款欧标达到H14级别的HEPA滤材——黑科技DURA-HEPA超积尘滤网，其具有两大特征，即超大容尘量，CCM指标可以超过国家标准P4的3倍，以及极致过滤效果，能针对PM0.3单次过滤效率达99.993%。

After analyzing present main mature purify technologies in the market， and on the premises of environmental protection and high efficiency， long term research and test on various technologies of active and passive purification was carried out. The passive psychical purification was finally chosen to be further developed. It’s a kind of static electricity HEPA filter + activating treatment activated carbon + nontoxic anti-bacteria material + multilayer reticular structure. Baomi Technology also cooperates with 3M company to develop a H14 (EU Level)HEPA filter material named Dura-HEPA Super dust retention filter， which has the following features:

①Super dust retention capacity， CCM index is 3 times bigger than national standard P4 level.

②Extreme filter effect， the single filtering effectiveness of PM0.3 is 99.993%.

PM0.3是对空气中直径小于或等于0.3微米的固体颗粒或液滴的总称，也称为可入肺颗粒物。PM0.3粒径小，富含大量的有毒、有害物质且在大气中的停留时间长、PM0.3飘散范围可超过1 000公里，因而对人体健康和大气环境质量的影响更大，PM0.3是最具穿透力的粒子，相比PM0.1等更小体积颗粒，PM0.3不受范德瓦尔斯和静电引力的影响。大颗粒的捕获机制同样对PM0.3影响小之又小。一些主流的国际组织评判滤网等级就是按照HEPA滤网对PM0.3的净化拦截效率来评判的。

PM0.3 refers to the solid particles or droplets whose diameter ≤ 0.3 μm， and is also named respirable particulate matter. It is minute， and rich in toxic and harmful substances， and it can suspend in the air for a long time and drift as far as 1 000 km， so it’s more harmful to the air or human body when compared with smaller particles like PM0.1 which are affected by Van der Waals’ force and electrostatic attraction. What makes it even worse is that it is also immune to the capture mechanism of large particles. That’s why some of the main international organizations judge the level of filters according to their PM0.3 capture rate.

随着“一带一路”推动沿线地区的经济发展，绿色技术、绿色发展成为主流趋势，更加节能环保的产品将更受欢迎。考虑到“一带一路”地区空气的特殊性，超积尘滤网DURA-HEPA不仅可以快速吸附并分解甲醛等有害气体，具有超大的容尘量和超高的拦截能力，在吸收固态颗粒物的同时，还能有效拦截各种细菌和病毒。可以广泛应用于家庭、学校、医院、工厂和大型商业体中的新风和室内净化系统，并大幅降低耗材的更换成本。

The economic development brought by the “Belt and Road” Initiative makes green technologies and development the main trend， and energy saving， environmental protection products more popular. Considering the features of the air quality along the “Belt and Road”， the super dust retention filter DURA-HEPA can not only absorb and discompose harmful substances like formaldehyde rapidly， but also intercept solid particles， bacteria and viruses. With super dust retention capacity and extreme filter effect， it can thus be widely used in residential buildings， schools， hospitals， factories and large commercial buildings， and slash the costs of consumable filter replacement.
