The secret inventory of the air purifier you don’t know
After more than 2 years of research on air pollution, as a member of the purification industry, I feel that it is necessary to share some results we have found.It is hoped that it will be helpful for the industry or solve the problem of pollution.
PM2.5 is not that you think so well to deal with
We found that it has many unexpected characteristics.Make many methods we think effective.
Disvoying ability: The diffusion capacity of pollution air is extremely powerful and fast.In an outdoor pollution environment, a closed clean space, as soon as it opens, is about 1 second, will be neutralized by pollution.This feature has made many measures that think of effective.It is also why the N95 mask should be worn so tightly, and a little gap will make it almost invalid.
Settlement ability:
It is far lower than our expectations. We believe that negative ions are a effective technology that promotes granular settlement. As soon as it is launched, it can immediately achieve the effect of settlement and purification.But the real situation is that because the PM2.5 particles are extremely small, it takes a long time to adsorb to the weight of sufficient settlement, such as ten seconds to tens of seconds, so if in a open space, stillWithout time, he was quickly invaded by the surrounding pollution.
Visualization:
We often say that the sky becomes ash is caused by PM2.5.When you see the sky, you know that the pollution is high, but when it is outdoors, there is a long visual distance.But in daily life, the space you live in are fragmented communities.With such a short distance, you cannot judge the level of pollution concentration through vision. Unless the pollution is really serious, you can not see her in front of me.Including many peoples eyes cannot judge whether these are PM2.5 or water vapor mist.
The pollution performance is simply explosive! There are wood! In the face of such pollution performance, what level can our purification ability reach? According to the survey, our current purification technology is concentrated indoors.There is almost no product outdoors to achieve purification.And what is the indoor purification technology? Lets take a look.
A problem facing indoor air purification
At present, the indoor purification technology is mainly concentrated in two types. The combination of one fan and filter. By circulating the air, the pollution particles in the closed space are continuously stuck on the filter to achieve the purpose of washing air.This advantage is that the cost of the filter material is relatively low and the life span is relatively long.However, the problem is that the more closed the space is, the better the indoor air will not be circulated. For a long time, people can easily lead to problems such as hypoxia and excessive carbon dioxide.
The second form is the form of a fresh air system, that is, filtering off the pollutants during the process of pumping outdoors.This method does not have problems caused by the former.However, because it is constantly filtering air with high outdoor pollution concentration, a large amount of pollutants instantly accumulate on the filter, which can easily consume the filter consumables.The cost is also relatively high.
Even if you only look at the purification ability, there are some problems
Generally, the setting of the purifier is purified for a space.The space is large, but the machine is small.It is necessary to purify the entire space so that people who move in the internal can breathe good air no matter where they are.This means that the purifier needs to allow the air anywhere on the space to absorb the purification of it, so as to purify the air in the space.But the problem is here. At present, the volume and height of the purifier, the air volume, and the angle of the air are not very good.
It is just a degree, there is no detailed stream design and consideration.It is quite difficult to complete the circulation of the entire space.Therefore, a large part of the machine, in fact, just keeps back and forth in front of the air outlet.Other locations may not change, or change slowly.Therefore, in addition to the filter filtering ability of the indoor purification effect, a large proportion should fall in the air -to -convection efficiency and adequateness.
In the end, there is a problem that the sealing nature of our house. Because PM2.5 has strong infection performance, especially when the outdoor high concentration, if the windows and door seams are not good.They will quickly invade in like a hole balloon.Therefore, doing a good job of closed work is also a very good thing.Over -sealing, there may be hidden safety hazards.Not sealed will be invaded by pollution.
Therefore, it can be seen that there is still a lot of room for improvement in purification technology.Especially outdoor purification is almost blank.People cant always stay at home! The revolution has not yet succeeded, and comrades need to work hard!
