Description
Technical field
The utility model relates to air purification fields, more particularly to a kind of air with detection fillter section service life structure
Cleaning equipment and fresh air system.
Background technique
2005 WHO (World Health Organization) just effect " World Health Organization's air quality criteria " text in global atmosphere sky
Gas environmental quality has carried out survey and evaluation, gives the threshold value for causing the major air pollutants of health risk and mentions to limiting value
Guidance is supplied.As shown in the following table 1,2:
Air quality criteria value and transition period target of the table 1WHO for particulate matter: mean annual concentration
Note: PM should preferentially be selected2.5Criterion value (AQG)
Air quality criteria value and transition period target of the table 2WHO for particulate matter: mean annual concentration①
Note: 1. the 99th percentile (3 day/year)
2. for the purpose of administration of health.Based on mean annual concentration criterion value；Accurately several selections depends on local day
Mean concentration frequency distribution；PM2.5Or PM10The distribution frequency of daily mean of concentration is generally near logarithm normal distribution.
China's economic development since two thousand eight is swift and violent, and people 's material life level is also obviously improved, but outdoor empty
Gas pollution is got worse, and PM2.5 problem has caused the whole people to pay close attention to, by taking Beijing as an example, by the real-time prison to PM2.5 in 2013
Surveying statistical result discovery PM2.5 mean value is 90.1 μ g/m3, PM2.5 maximum annual average is 646 μ g/m3.Especially at 2014 2
The weather more than serious pollution of month PM2.5 has 11 days, wherein having continuous 4 days PM2.5 is more than 250 μ g/m3.The study found that room
Interior air quality decline directly endangers occupant's health and reduces the working efficiency of labourer.
By investigation find, influence indoor PM2.5 concentration factor it is main there are two, one be outdoor PM2.5 concentration,
Especially when outdoor concentration is higher, indoor concentration generally can be also consistent with outdoor；One is indoor pollution sources release,
The especially fine particle of the generations such as cooking, smoking, personnel activity, semi-volatile organic matter, equipment operation.
For these reasons, air cleaning facility is generally provided with filter structure such as air purifier or new blower,
It is general, since the service life of filter screen is limited, to be replaced in time in the case where filter screen failure using filtering web form, and
Currently, how long general to calculate one typically testing out continuous operation by experiment in air purifier and new blower
The strainer out-of-service time, generally replaced a whole set of strainer in 3-6 months time.
Filter screen service life is calculated in use experience algorithm, this numerical accuracy can have a long way to go, in haze ratio
In the case where more serious, as soon as filter screen is no longer valid, is not only unable to clean room if continued to use in the case where possible month
The fresh air of interior and outdoor introduction can also produce by boasting the particulate matter being saturated in filter screen, the secondary pollution of air be caused, in outdoor
In the preferable situation of air, the service life of filter screen will extend, and routinely replacement in 3-6 months is primary, can also waste in this way
Filter screen.
Face predicament below in i.e. current air purifier and new blower use process: 1. strainer premature failure causes
2. strainer can also use for secondary pollution, and but prompt will replace strainer.
It can be seen that above-mentioned existing air cleaning facility is in structure, method and using upper, it is clear that there are still have it is inconvenient with
Defect, and need to be further improved.How to found a kind of can in real time, accurately detect the air cleaning in fillter section service life and set
Standby, becoming current industry pole needs improved target.
