President of Honeywell China talks about harnessing haze through science and technology

CEO of Honeywell China, who is also the first and meets the requirements of the "leadership in energy and environmental design" (LEED) standard, Sheng Weili recently published one of the insight articles in the series of imagination and deep breathing, "Sheng Weili: harnessing haze through science and technology under the dome should be the first to break through", saying that it is not advisable to talk about haze color change, but it should not be used to it. Today's technology can help enterprises and governments effectively control and gradually control air pollution

with the acceleration of economic and social development and urbanization, the situation of air pollution in China is becoming increasingly serious, which is highlighted in the frequent occurrence of severe haze in urban agglomeration areas such as Beijing Tianjin Hebei and the Yangtze River Delta, which has brought serious negative effects on public health

the Chinese government is strengthening the control of air pollution. The newly revised "environmental protection law" was implemented at the beginning of 2015, which not only increased the responsibilities of local governments in dealing with environmental issues, but also further clarified the constraints and penalties on enterprises and related persons who illegally discharge pollutants. This year's government work report also clearly proposed to fight the battle of energy conservation and emission reduction and environmental governance, and listed the in-depth implementation of the air pollution prevention and control action plan as one of the main directions

however, diseases come and go like a mountain. Combating smog will not happen overnight. It requires the cooperation and long-term joint efforts of all sectors of society. On the one hand, we should see that the prevention and control work is very urgent. We should speed up the improvement of energy efficiency, reduce emissions, and actively deploy clean energy to control and treat air pollution at the root. On the other hand, we should also recognize the long-term, arduous and complex nature of air pollution prevention and control. At this stage, we should pay particular attention to the health problems caused by air pollution and strengthen the protection and education of public respiratory health

it is urgent to improve the awareness of protection

how to deal with haze rationally? On the one hand, it is not advisable to talk about haze. Atmospheric haze is not a unique phenomenon in China. In history, some European and American countries have also experienced serious air pollution incidents in the rapid development stage of industrialization and urbanization. As China strengthens environmental legislation, actively promotes energy conservation and emission reduction, and gradually changes the mode of economic growth, China's air pollution can be effectively controlled and gradually treated. In fact, today's technology can effectively help enterprises and governments make comprehensive, rapid and substantial progress in reducing air pollution and achieving energy conservation and emission reduction

on the other hand, the attitude that more and more people are accustomed to frequent haze weather is more worrying. When the haze just hit, people were terrified of PM2.5 (fine particles with particle size less than 2.5 microns), so they tried to wear masks and reduce outdoor activities. Today, more and more people don't even wear masks, air purifiers are just a decoration when they buy them, and outdoor activities are also carried out as usual in haze days

how much does haze affect human health? There are still some disputes. However, preliminary research and more and more evidence have proved that air pollution, especially fine particles such as haze, has a great impact on people's health. In haze days or poor indoor air quality 16. Electromechanical power: 5.5kW, 3 ф At 380V, if you do not pay attention to respiratory protection for a long time, it will indeed cause a series of diseases, including asthma, bronchitis and cardiovascular disease

China's society and people are still far from enough aware of the harm of haze pollution, especially its harm to health. To some extent, the public health risks brought by smog and how to strengthen the education of public protection awareness are even more urgent than the air pollution control itself

understand the power of science and technology

the power of science and technology can not be ignored in helping to deal with the health threats brought by air pollution and haze. Since the middle of last century, scientists and engineers have been exploring and working hard on how to deal with indoor and outdoor air pollution and how to better protect people's health and safety

nowadays, more and more respiratory health-related technologies are also entering our daily life. Only by better popularizing relevant technology and knowledge among the public can we help everyone cope with pollution scientifically and better protect themselves and their families

sensing technology: for the haze weather in China, continuous monitoring method is usually used in PM2.5 monitoring in China to monitor the deposition quality close to the site. Such monitoring methods have strict requirements for the accuracy of air temperature, humidity, air flow rate and other data, and a little deviation can lead to very different monitoring results. At this time, we need to use sensors with high sensitivity and accuracy to ensure the accuracy of data in the PM2.5 monitoring process

gas detection: the formation of haze is largely related to our daily production and life, and they are often accompanied by the production of toxic and harmful gases, threatening our health. For harmful gases in the industrial field, the advanced gas detection system can detect very small amounts of flammable, toxic and low oxygen hazards, effectively protecting personal and property safety. At present, indoor air quality monitoring technology can realize real-time monitoring of indoor air temperature, humidity, carbon dioxide concentration, PM2.5 concentration, and harmful gas concentration, and can be applied to residential, commercial buildings and public places, so that we can take measures at the first time

electrostatic precipitator: with the public's attention to indoor air quality, environmental control and air purification technologies originally used in precision aerospace and harsh industrial fields are also entering civil and commercial fields. Aerospace itself is a very narrow and confined space. For example, in an airliner, where hundreds of people sit, a long-distance flight may take more than ten hours. How to manage the air quality in the cabin is a great knowledge. In China, the commercial air purification solution with high-voltage electrostatic precipitation technology as the core has been successfully applied to many buildings and public facilities. It can not only force the suspended particles with a static charge above pm0.3 in the air to be collected on the dust collection chamber, but also inhibit the growth of various bacteria, viruses, dust mites and other microorganisms through the High-Voltage Ionization field

filtration and adsorption: efficient filtration media can become the nemesis of chemical pollutants and harmful gases, effectively decompose and adsorb chemicals and odors in the air, and solve the problem of total volatile organic compounds (TVOC) pollution indoors, especially in the central ventilation system. In addition, the leading molecular sieve adsorbent products can adsorb harmful substances and small particles in indoor air and help improve indoor air quality. Some refineries, petrochemical plants and industrial parks in China have begun to use such adsorption products. Honeywell developed the jingnengtm all-round air purifier in Shanghai last year. It also used the self formulated active catalyst and special adsorbent for the first time, and integrated many leading technologies such as high-voltage electrostatic dust removal, which can quickly remove PM2.5, bacteria, various odors and harmful gases in about 150 square meters of indoor space

personal protection: in haze days, when people lack effective protection outdoors, PM2.5 will enter the bronchus after being inhaled into the human body, causing early symptoms such as dry throat itching, rhinitis, cough, and a series of diseases over time. It is worth mentioning that only professional protective masks can effectively block PM2.5 particles. As the public pays more and more attention to respiratory health, professional personal protective products represented by high-performance PM2.5 protective masks are also entering people's daily life because of their higher protective effect. In the production sites of some specific industries, air pollution will cause great harm to the health and safety of workers, which requires the next generation of more comfortable, smarter and more efficient personal safety protection solutions, which can not only provide better protection for workers from head to toe, but also help them significantly improve production efficiency

mobile Internet: with the reduction and popularization of the cost of wireless applications, broadband access and mobile technology applications, we will increasingly create a safer, healthier and more comfortable breathing environment and experience through intelligent Internet. We can not only realize real-time monitoring and understanding of indoor air quality through mobile Internet technology, but also remotely control and adjust indoor temperature, humidity and air quality through terminals, so as to improve the indoor environment in time

is not only a business opportunity, but also a new normal for China's economy. However, the new normal also means new strategic opportunities for many local and multinational companies that pay attention to energy conservation, environmental protection, health and safety and technology driven

China's air pollution covers a wide range of regions and involves a large population, which is unprecedented in human history. China has a huge and urgent demand for products and technologies related to respiratory health, such as air purification and personal protection. Its scale and depth are unmatched by other countries and markets

for enterprises, R & D and innovation based on the Chinese market should focus on solving the most basic problems in the production and life of the country and people, and return to the most basic needs, such as clean water and air, energy conservation, safety, etc. We should not only help China make good use of existing technologies to effectively resist the public health risks caused by air pollution, but also actively improve and innovate based on existing technologies, especially promote cross domain cooperation and innovation, actively explore the commercialization and commercialization of relevant technologies in aviation and industry, and help the Chinese public better cope with smog and all kinds of indoor and outdoor air pollution

respiratory health problems caused by air pollution involve all aspects of our daily life. We need to pay attention to the air quality of the surrounding environment not only in the home environment, offices, various public places, subways, airports, railway stations, driving, fitness and entertainment activities. This also requires a full range of respiratory health products to help the public comprehensively improve the respiratory environment and resist haze and pollution

for enterprises, all these are promising fields, but they should also bear the burden to prove their doubts and inferences
