After more than 2 years for the air pollution research, I as a member of purification industry, felt the need to share some of the results of our study found. Hope it is helpful for trade or solve the problem of pollution.
PM2.5 is not as good as you want to deal with
We found it to be a lot of unexpected features. We consider effective means weak. Speck iPhone 5 Case
Spread: the spread of air pollution, is extremely powerful and fast. Outdoors in a polluted environment, clean space with a closed, opened around 1 second, will be immediately neutralized by the pollution. This feature, so that many thought had the effect of the measures ineffective. Is why the N95 respirators should be worn so tight, a little bit of gaps will make it almost failure.
Settlement: far less than we had expected, we believe that the negative ion is an effective promotion of particle technology, launched in the past, you can achieve the effect of purification of settlement. But the truth is, because PM2.5 particles are extremely small, adsorption to the settlement of sufficient weight, takes a longer time, for more than 10 seconds to dozens of seconds to a few minutes, so if you are in an open space, haven’t had time to settlement, will soon be the pollution of the invasion.
Visualization: we used to say, the sky gray is caused by PM2.5. Say sky knew a high pollution, but those who are outdoors when there is a long distance. But daily life, your space is fragmented in smaller areas. Such a short distance, you can’t visually to determine the pollution concentration level, unless the pollution is really quite serious when, you can let you see in front of her. Includes a lot of times the human eye is unable to judge whether these PM2.5 or water vapor mist. Speck iPhone 5 Case
Blast table to have contamination! Has there! Faced with such pollution, our ability to purify and to what level? According to the survey, at present our purification technology, focused on the Interior. Outdoor almost any product can achieve the purpose of purification. Indoor purification technology, we take a look at.
Challenge for indoor air purification
Currently focused on two main types of indoor purification technology, a combination of fans and filters, by filtering the air, kept within the closed space of the contaminated particles stick to the mesh, so as to achieve the purpose of washing the air. This edge is the material costs are relatively low and relatively long life. But the problem is that space as close as possible, and therefore makes ventilation is, people in there for a long time can easily lead to hypoxia, too much carbon dioxide, and so on.
Second form of fresh air system, the incoming outdoor air process filters out pollutants. This way there is no issue arising out of the former. But because it is constantly filtered highly polluted outdoor air, lots of moments of pollutants accumulate in the filter, it’s easy to filter supplies running out. Costs are relatively high.
Even if only purification ability, there are still some problems
General Purifier set is to purify a space. Space is very big, but very small. Need to make the entire space is clean, people can make internal activities regardless of where can good air to breathe. This representative, Purifier needs to make a space anywhere in the purification of the air is drawn through it, in order to purify the air in space out. But the problem is here, current volume and height of the Purifier, air volume, the wind angle, are not very well designed. Just some degree not convection design and consider in detail. To complete the entire space convection is quite difficult. A large part of the machine is actually not far from the location in front of its outlet constantly cycling back and forth. Other locations may not change, or change very slowly. Indoor purification effect in addition to the filter capacity, a large proportion will be on the air flow efficiency and adequacy.
One more thing…
Finally, there is a problem, is the seal of our House, because PM2.5 is infected with powerful performance, especially high outdoor concentrations of case, if Windows, door seals well. They will be like a balloon with a hole, rapidly infecting in. So close is a very cerebral matter. Sealing too much, and may create a security risk. Seal will not be contaminated invasion.
So as you can see, purification technology also has great room for improvement. Especially outside of purification, almost blank. People can’t always stay at home! Revolution has not succeeded, comrades need to!
