Description
Technical field
The present invention relates to a kind of air cleaning unit more particularly to a kind of air cleaning units of formaldehyde.
Background technique
Air purifier is to refer to adsorb, decompose or convert the pollutant in various air, effectively improves room air
The product of cleannes.There is application in house, medical treatment, industrial circle.Most important function is the particulate matter removed in air, packet
Include anaphylactogen, indoor PM2.5 etc., at the same can also solve the interior as caused by finishing or other reasons, the underground space,
Interior volatile organic matter air pollution problems inherent, and formaldehyde is as being a kind of common pollution gas, all to environment and human body
Biggish harm can be brought, for having occurred more processing technique and product on the market in terms of purifying formaldehyde.
Shanghai Communications University's master thesis " load type double-metal composite oxides ozone auxiliary catalysis degradation low concentration
The performance study of formaldehyde " it refers to using cobalt nitrate in chapter 3 " Co-MnOx/ZSM-5 Catalytic Ozonation low concentration formaldehyde "
With manganese nitrate molar ratio 1:1 match, be added mass ratio 5%ZSM-5 it is molecular sieve carried be fired into 500 DEG C on ceramic honey comb urge
Change plate, match and the ozone yield of two hours 3m3 closed cabin ozone cumulative amount 2290ppb of about 10mg/h, 60m3/h air quantity, two is small
When 3m3 closed in space in the formaldehyde of initial concentration 1.07ppm is down to 0.44ppm, ozone concentration is in 60ppb or so;It hands in Shanghai
Logical University Ph.D. Dissertation " research of plasmon coupling catalytic elimination volatile organic matter " chapter 5 " meets metal oxidation
321ppb ozone cooperation cobalt nitrate and manganese nitrate Co/ are referred in the experimental study of object coupled high voltage electrostatic field removal indoor VOCs "
Mn molar ratio 1:1, mass ratio 5%ZSM-5 molecular sieve, the catalytic plates of 500 DEG C of firings, under 60m3/h air quantity, 3m3 is closed within six hours
By formaldehyde removal 95%, the Co/Mn molar ratio 1:4 formaldehyde removal 80% of initial concentration 0.9ppm in cabin, ozone concentration is kept
In 30ppb hereinafter, more than two correlative theses be all with processing formaldehyde it is related, substantially all with ozone occurring source cooperate catalyst with
Concentration of formaldehyde is reduced, but oxygen occurring source employed in above two papers is high-voltage electrostatic field.The normal work in high-voltage electrostatic field
As when the ozone amount that generates it is smaller, be not able to satisfy the ability of coupling and catalyzing plate obvious degradation formaldehyde;Only when its size is sufficiently large,
Perhaps voltage is increased to a certain amount of or discharging gap and is reduced to certain distance, and oxygen in discharge breakdown gap generates obvious draw
When arc phenomenon, a large amount of ozone can be just released, but can also ionize nitrogen at this time, generates a large amount of nitrogen oxides.According to existing text
It offers, this type catalyst acts on nitrogen oxides without obvious removal, and nitrogen oxides is diffused into air and can have obviously to human body
Harm, electric field arcing can also generate corresponding electromagnetic interference to other electric appliances, therefore high-pressure electrostatic is uncomfortable as ozone occurring source
It closes;ZSM-5 molecular sieve is used in two papers simultaneously, this molecular sieve price is higher at present, average 70 yuan of 100g price
RMB or so, large scale investment higher operating costs;Its formaldehyde removal rate is also relatively low, and the initial concentration two of 0.55mg/m3 is small
When also only eliminate 61.8%;It can be calculated to obtain its equipment size according to described in paper to be 0.5*0.15*0.15m3, but contracted
Small size will affect the removal efficiency of its formaldehyde;Last gas passes through from narrow air duct inherently generates biggish noise, such as
Fruit is to reduce noise not necessarily to can guarantee enough formaldehyde removal effects to reduce air quantity also.
Therefore, for the ozone occurring source of existing formaldehyde purifier be high-voltage electrostatic field be harmful to the human body, ZSM-5 molecule
The problems such as price is higher, formaldehyde removal rate is low, size is larger and noise is biggish is sieved, becomes those skilled in the art and urgently solves
Certainly the technical issues of.
