The right medicine: Interpretation of mainstream purification technology
In the last week of September, the people who were waiting for the 11th holiday were ruined by an uninvited guest. The smog weather in the past few days made the blue sky disappeared in the past few days, but the street was more. A lot of masks. Eleven is the peak season for e-commerce promotion. Under the influence of smog, the air purifier market will reproduce the buying spree, but in the face of a wide variety of products, do you really know which one to choose? What are the current mainstream purification technologies, and what is the difference between them?
In order to choose a suitable air purification product, we must first understand the types of indoor pollutants before we can prescribe the right medicine. At present, indoor pollution sources can be mainly divided into 8 types: dust pollution, adsorbable particulate matter pollution, nicotine pollution, kitchen oil smoke pollution, indoor odor, bacteria, viruses and chemical pollution caused by decoration. The most common and most serious of these is the adsorption of particulate matter and chemical contamination.
Main indoor pollution source
For different sources of pollution, the choice of purification technology is also very different. When we understand the source of pollution, and then select products according to their own needs, it can effectively purify indoor air. Today, I will talk to you about the current mainstream air purification technology principles and their advantages and disadvantages.
Activated Carbon Technology & Negative Oxygen Ion Technology
â— Activated carbon technology: strong adsorption capacity
Activated carbon is arguably the most common purification technology. It is believed that most people are no strangers to it. Its superior adsorption capacity is widely used in many technical fields. It is mainly used in the fields of medicine, chemical industry and food processing. In the 1970s, China began to apply it to industrial wastewater treatment, and gradually became one of the main methods for secondary or tertiary treatment of industrial wastewater. Its superior adsorption capacity for impurities or sources of pollution makes it the first choice for many air purification products.
Activated carbon technology is quite mature
So how does an air purifier based on activated carbon adsorption technology work? Simply put, the clean air filtered through activated carbon is re-released through a powerful fan. As the most basic purification technology at present, most air purifiers have applications. At present, the commercially available activated carbon is mainly divided into three types: coconut shell, shell and coal, among which coconut shell activated carbon has the strongest adsorption capacity.
Advantages: strong adsorption capacity, able to effectively absorb most harmful substances in the air
Disadvantages: The adsorption effect of activated carbon is relatively short. Once the adsorption amount reaches saturation, the adsorbed pollutants will be released to cause secondary pollution. Therefore, such purifiers must frequently change the filter material to avoid secondary pollution.
