Description
Technical field
The present invention relates to air purifier field, in particular to a kind of gas phase removes the air purifier of formaldehyde.
Background technique
The utility model patent " electrostatic air cleaner " that designer of the present invention applied respectively in November, 1993,1997
(patent No. 93226519.7), utility model patent " sterilizing aircleaner " (patent No. 97234337.7) and utility model patent
" combined static field device " (patent No. 97106376.1), which discloses, a kind of can reach hospital disinfection using electrostatic absorption principle
The air purifying sterilizer of sanitary standard.The product of these patents meaning does aerosol test in 30 cubic metres of environmental chambers, kills white
The efficiency of staphylococcus can only achieve 99.9%~99.99%；And above-mentioned patent is mainly for the bacterium in air, without reference to
The effect of gaseous formaldehyde in control room.
A kind of air cleaning unit based on electrostatic precipitation principle that above-mentioned patent proposes, because there are ozone and nitrogen oxidation
The danger of the secondary pollutions such as object has not become the mainstream technology that gas phase removes formaldehyde.
Known in those skilled in the art, the exceeded event for causing tragedy of indoor formaldehyde is produced repeatedly, and masses are to first
The attention rate of aldehyde is gradually increasing, and under this background, numerous positive boostings of brand remove the R&D and promotion of formaldehyde type sky net products,
Except aldehyde performance boost becomes the new racing track of empty net industry.
Air purifier is generally used " three high and one low ", i.e., high CADR, high CCM, high purification efficiency are measured with low noise.
The CADR index of air purifier, also referred to as Clean air delivery rate.CADR is one and is related to indoor air cleaner production
Product are using feature and can reflect the performance indicator of its detergent power, unit m3/h.It is existing except formaldehyde air purifier
Except particulate matter CADR can not accomplish still to be greater than 800m simultaneously with formaldehyde CADR value is removed3/ h, 800m3/ h value is considered as room
With the maximum value of air purifier CADR.
Air purifier has indicated with the performance except particulate matter with " remove aldehyde coefficient " except formaldehyde simultaneously.
" removing aldehyde coefficient " refers to except particulate matter CADR and the ratio for removing formaldehyde CADR, existing at present to remove formaldehyde air cleaning
" the removing aldehyde coefficient " of device is generally less than 0.5, is not above 0.8.
Purification efficiency is the energy efficiency indexes of air purifier, state compulsion regulation, the highest of air purifier purification efficiency
Value is 11m3/ (w.h), it is existing except formaldehyde air purifier can not reach this index.
CCM is known as the accumulation purge amount of air purifier, and the index and the effective of air purifier scavenging material use the longevity
It orders related.When dropping to the 50% of initial value except formaldehyde CADR value, the total amount of the formaldehyde of air purifier removal, the referred to as air
Clarifier removes formaldehyde CCM.National air purifier GB18801-2015 standard provides F4 grades, i.e. it is most that CCM, which reaches 1500mg,
The figure of merit.
Noise is of great significance to air purifier.Good noise control is the guarantor of maximum detergent power
Card, if the most high-grade noise of an air purifier be it is insufferable, the maximum detergent power of this product will be just as
It is illusory.Noise is one of air seven greatly pollution, is exactly that polluted more than 60dB (A) indoors.The strong noise one of air purifier
It is directly that one of the sector denounces.The air purifier in room is all health type household electrical appliance relevant with air-flow to air-conditioning,
Air-conditioning national standard provides the noise maximum value of room air conditioner no more than 60dB (A) already.Exceeded noise and exceeded
The pollutants such as PM2.5, formaldehyde are equally flagrant.We cannot generate new pollution while removing depollution.It is existing
Except formaldehyde air purifier quotient cannot guarantee except aldehyde coefficient be greater than 1.0, except particulate matter CADR with remove formaldehyde CADR surpass simultaneously
Cross 800m3/ h value, and purify the 11m that efficiency reaches national regulation3Under the conditions of/(w.h) is such, by noise control in 60dB
(A) in index.
The haze epoch afterwards, except aldehyde is the key that the competition of sky net products is won.It is existing except formaldehyde air purifier is " three is high
One is low " it is problematic in that with technical parameters aspects such as " removing aldehyde coefficient ", therefore be very restricted in practical application, indoor first
Aldehyde pollution problem has no better method so far to be controlled.Except the existing above problem of formaldehyde air purifier, it would be highly desirable to need
Change and improves.
Therefore, this industry problems how is solved, is always the target of field technology personnel struggle.
