Beijing has the world’s largest air purifier to fight smog

A heavily polluted fire has attacked the city, taking people into their rooms, and plans to deploy the world’s largest outdoor air purifier, designed by Dutch engineers, in the smoggy capital of Beijing. The last-minute inspection of Beijing 751 D Park Art Zone will be held shortly after the release of Daan Roosegaarde, and tours will be held throughout the country. Non-governmental organizations and Environmental Journalists from the Ministry of Environmental Protection of China.

The tower can capture about 75% of the small particles around PM2.5 and PM10, then release clean air and create “bubbles” of fresh air around it. Since the beginning of October, ozone-free ion technology has been plagued by serious smog in Beijing. The city’s environmental protection department issued a “yellow warning” on air pollution on Tuesday.

“Yellow warning” is the third most serious level in the four-level color-code warning system, red is the most serious, orange is the second most serious, and blue is the most serious pollution level.

Although the average PM2.5 density of deadly contaminated particles is more than 300, and although the cold front cleared the smoke in the morning, CFEJ Secretary-General Liu Guozheng has never forgotten the responsibilities of the authorities, as they said, they intend to warn and urge the masses to gather to fight the smoke.

Every day, he said, the people, blood and others were troubled by the operation of the tower and asked the authorities to contain dangerous sources of pollution.

“The so-called sacred smoke cleaner is like a performing art, and there is little difference in cleaning urban air. It wastes polluted air and exhales the fresh air, but only a few. The air will continue to be polluted, “Sina Weibo users’comments are quoted every day.

Air purifier sales boom caused by pollution in China

If you live in China now, especially if you live in a big city like Beijing or Shanghai, you must be familiar with the recent pollution wave. Looking at the Bund from the top of the Oriental Pearl Tower in 2007, I remember that the city slowly disappeared in front of me, but the recent photos from China are even more worrying.

Recently, the smoke measurement of the Shanghai air quality index has reached more than 450, but some values are less than 100, but “display warning, if more than 200, the indicator must be inside.” Therefore, many children are at home, at least one elderly person carries a 15 kg air purifier. In fact, from masks to air filters, everyone in the room tries to maintain at least a degree of contact with the surrounding air.

As you can imagine, this has also led to a recent surge in the number and type of air purification systems sold, as well as a search for Taobao Air Purifier, China’s largest online business website, which has increased by 513% compared with Dec. 10. The actual sales of air purifiers increased 267.50% year-on-year, 1264.40% year-on-year.

Outdoor air purifier reduces your waiting by 40% smoke

According to the Ministry of Environment, China’s campaign to clean up air pollution last year has reduced the level of dangerous particulate matter in the atmosphere by 11%, but there is still a long way to go before the public breathes air every day. Of the 74 cities surveyed, only 8 met basic domestic air quality standards.

Meanwhile, antifouling masks are a popular project, and start-ups that produce new indoor air purifiers are lowering prices. New inventions currently being tested in Hong Kong are causing an average of 40% of outdoor air pollution claims to be reduced.

Design and engineering companies Sino Green and ARUP research project Urban air purification systems look like minibus stops, but they are deliberate. According to Sino Green, streets can benefit from air purification.

In the system prototype being patented, the air is sucked into the system from the bottom entrance, and then air is circulated through the bag filter to remove fine suspended particles (PM10 and PM2.5) which effectively exit the shutters.

The first green product standard for the national air purifier industry is expected to be released in the second half of the year.

BEIJING, April 22 (Reporter Pan Xulin) 22 journalists from the Environmental Certification Center of the Ministry of Environmental Protection, the first batch of green product standards for the national air purifier industry are expected to be formally promulgated later this year, and they are told that they will be completed. GB/T18801-2015) The basis of the new national standard “air purifier”. The maximum purifying index of PM 2.5 air purifier products is only used to remove noise, only transparent rooms of different sizes, and it is almost the first time to introduce standards for consumers and provide proof for choosing suitable air purifier products.

On the same day, the Environmental Certification Center of the Ministry of Environment held a seminar on the standard of environmental labels for air purification in Beijing, a representative of the Environmental Certification Center of the Ministry of Environmental Protection, the Tsinghua Environmental Testing Center and the Testing Center of the Beijing Center for Disease Control and Prevention, and participated in the introduction of Gambian microbial analysis and air purification by other units. The standard for environmental labeling of carburetors.

Experts said that the air purifier industry is a relatively young industry, but there are many problems and hot spots in the market for a wide range of purification technologies. It is called high performance, performance is lower than advertising, and the actual effect of advertising air purifier does not match, seriously affecting consumer confidence in air purifier products. Indoor pollutants have serious consequences, the key is that consumers choose appropriate products according to their own needs.

Standard PM2.5 From standard to process, besides choosing the key indicators and unified detection methods for indoor air pollutant purification indicators such as PM2.5, formaldehyde, benzene, etc., which are used for product design, manufacturing, use, final waste and recycling life cycle management, the manufacturing process of pollution prevention for raw materials, electrical and electronic products, consumers are required to use PM2.5, formaldehyde, and benzene. Relevant indicators, the determination of formaldehyde and benzene in various areas of the room, consider using air purifiers, looking for a clean sleep mode and consider focusing on the strongest product purification mode, so it is not only a standard. In addition to the maximum CADR value of the product, the CADR value of silent products also has serious limitations.

“Three Chaos” Phenomenon in Air Purifier Market

There are all kinds of dazzling advertisements in stores – formaldehyde, 99% PM2.5 removal rate, and many others. Air quality is a major problem. Are these air purifiers really so effective?

In the first half of the year, Shengyi Branch inspected 244 enterprises in the air purifier Regional Chamber of commerce, forged advertisements according to law, punished product quality, checked out 19 brands and 36 models of air purifier standards, certification qualifications were wrong, and counterfeit offenders and reformers found in the water purifier market that “certification confusion, data confusion, there are” Favorable to the phenomenon of confusion.

The so-called “certification disorder, confused data, advertising disorder”. Some businesses, under the banner of certification agencies, use air-cleaning new products for advertising, which are actually false certification. These so-called “certification agencies” are simple environmental protection departments, not accreditation agencies, or some data may indicate that there are no relevant certification standards in the country. Commercial content air purifier performance test report is not standardized, test report test environment and time, data structure, for example, some people claim that a 99% purity test environment of water purifier is not a normal living test space, but a 1 cubic meter enclosed space. Allergy and exaggeration, distortion, misleading consumer support roles, such as “cold is a cure”.

Shunyi Industrial City Branch reminds consumers to buy air purifiers, pay attention to supermarkets or stores to buy household appliances, store purchase invoices, air purifier performance parameters, check test reports and related promotional data. Whether it fully conforms to the national standard test, pay attention to the filtering function, work and the type of selected basic air purifier, etc.

Drafting of Green Standards for Air Purifiers

Since the implementation of the new national standard air purifier in March this year, the turbulent scene of the empty network market has been standardized, and the new national governance standard is called market shock. It is reported that the first national standard for green products in the air purifier industry has been officially issued and expected in the second half of this year.

This standard is the new national standard “air purifier“. PM2.5 air purifier product’s maximum purifying index, the only cleanroom foundation used to eliminate the noise of different sizes (GB/T18801-2015 basis) for most consumers to introduce the standard to select the appropriate air purifier products to provide proof.

From now on, the air purifier industry has been relatively young, but it not only has a wide range of purification technology, hot issues in the market but also has many problems. Against this background, the new national standards for air purifiers have been drafted and formally implemented on March 15, 2016. Once created, the new standards will be officially released later this year, which will accelerate the formulation and implementation of new standards or industry restructuring.

Relevant industry officials said that under the catalysis of the two standards, the formal introduction of the new national standard air purifier did not take time to start drafting an empty net for the implementation of the green product standard, which guided the clearance of the net market to achieve the current regulations, and its role in strengthening the more rational choice of consumer goods improved the quality of household appliances.

Air purifier technology

For those who have a direct knowledge of cleanliness, cleanliness technology and the machines used, it is not just the quality of the air purifier that is needed. Understanding second-hand air purifier technology What is the current air purifier technology? What kind of effective purification technology is the best? HEPA filter: One of the most commonly used technologies in air purification. The ability to absorb 99 microns 0.3-micron aerosols (0.3-micron filter size is the most difficult) has the advantages of safety and effectiveness, but the most important technology is to remove particulate pollution in the air, but its drawback is that the design of HEPA air purifier has excellent sealing. Otherwise, the air will bypass the filter and lose its filtering effect.

According to the current application conditions of air purifier purification technology, it can be divided into three types: passive, active, active-passive hybrid fine mechanical filter, electrostatic electret filter, high voltage electrostatic precipitator, negative ion and plasma with HEPA filter, activated carbon, charged ion, photocatalyst. Compared with the HEPA filter, the most commonly used purification technology is usually used in air purifier 4.

Activated Carbon Filter: Activated Carbon Air Purifier is internationally recognized as an early high-adsorption material for gas mask activated carbon adsorption technology: physical adsorption and physical adsorption of organic molecules to chemically adsorbed gaseous polymer pollutants porous structure is adsorbed by activated carbon (such as TVOC such as benzene), mainly chemical adsorption of small molecules such as gaseous pollutants (formaldehyde, hydrogen sulfide, nitrogen). Oxides, etc.

Two types of nano-water plasma technology, nano-ion technology, and water purification technology, are mainly used for air filtration. The advantage of nano-water plasma technology is that plasma can help filter particles and kill charged ions adsorbed on the surface. Cluster purification technology is another important species. The air suspended in fungi is released by a device that generates plasma clusters by high voltage discharge. Qualitative same positive and negative groups. Viruses and other harmful substances are degraded to remove the effects of air.

Photocatalytic purification technology: a kind of nano-titanium dioxide with photocatalytic function, which can be expressed together, can degrade toxic gases in the air, but the purification efficiency is very low. Research shows that the photocatalytic process is toxic and it shows the intermediate products in production. From the point of view of dust sterilization, this technology is relatively reliable.

From the above, we can see that the advantages and disadvantages of air purifier technology, mainly HEPA filter, activated carbon filter refining two technical bases, purification technology has more significant advantages.
