Description
Technical field
The present invention relates to technical field of air purification, especially a kind of small indoor formaldehyde purifier.
Background technology
Modern economy develops rapidly, and living standard increasingly improves, and people increasingly focus on the comfort level of living environment, various
The interior decoration of various kinds is more and more universal, and the material that interior decoration uses is likely to release formaldehyde.Various wood materials, floor
Material, thermal insulation material and coating etc. are likely to become potential source of release.Formaldehyde uses extensive industrial materials as a kind of,
One of important use is for synthesizing Lauxite, carrys out further synthetic adhesive.This urea formaldehyde resin adhesive bonding
Particieboard, medium density fibre board (MDF), glued board and core-board etc. it is more in the use of the backboard of furniture, partition board and bottom plate,
Formaldehyde is released when reversible reaction occurs as product from furniture etc..
Formaldehyde can generate stimulation to eyes and the upper respiratory tract, cause acute allergic reaction;Formaldehyde has electrophilicity, energy and people
Protein is had an effect in body, influences the normal performance of protein function.Formaldehyde can be to the sensoriums such as the smell of human body, breathing
System, immune system and central nervous system generate damage, it is also possible to generate harmful effect to human genetic material.Concentration mistake
Height may result in pulmonary edema, pneumonia, and modificator gene mutation even results in death.
Simultaneously because the improvement of living environment and housing condition, the closure of building is also continuously improved, and reduces interior
Frequency is exchanged with outside air, the exacerbation for room air pollution creates condition.
At present, there are many indoor formaldehyde minimizing technologies, for example, ventilation method, biological clarification, absorption method, Ozonation,
Photocatalysis, lower temperature plasma technology and catalytic oxidation etc..Windowing ventilation method is that removal indoor formaldehyde is most simple to operation
Method, but during practice, by indoor formaldehyde deenergized period is long, release potential source mostly with the practical problems such as outdoor weather
Limitation, final effect also has very big uncertainty.Using plant or microorganism removal indoor formaldehyde, there is certain effect really
Fruit, but action time is slower, and is limited, and it is relatively low to be confined to concentration of formaldehyde by plant or microorganism formaldehyde tolerable concentration
Situation.Indoor formaldehyde is removed using absorption method, can not CO thoroughly be decomposed by indoor formaldehyde to the absorption of pollutant2With
H2O.After the adsorption capacity of adsorbent reaches saturation, secondary pollution can be caused to environment during being desorbed.Meanwhile it inhales
Attached method stability is not high, the variation of the conditions such as indoor temperature, humidity, pressure, and the absorption of adsorbent PARA FORMALDEHYDE PRILLS(91,95) can all generated not
Stability.Ozonation removes formaldehyde due to the inherently harmful substance of ozone, and operates more complicated, is also easy to produce two
Secondary pollution.
