Formaldehyde purifier, also known as formaldehyde purifier, is equipped with a special de-formaldehyde filter and filter air purifier, its core principle is to accelerate air circulation, adsorption, and decomposition of formaldehyde and other chemical pollutants in the air, in addition to adsorption, there are mechanical filtration, electrostatic electret filtration, high voltage static electricity dust collection, anion, and plasma method and other deformaldehyde methods. Formaldehyde purification machineThe formaldehyde effect of the strong and weak mainly depends on the cartridge and filter. It can only play an auxiliary role and can be used together with other formaldehyde supplies.
Formaldehyde purifier how to remove formaldehyde?
Formaldehyde is very harmful, so after the renovation will through a variety of methods to remove formaldehyde, from a chemical point of view, the weight of formaldehyde is lighter than the air, as long as there is air circulation, formaldehyde can be discharged with the air to the outdoors, so there is a formaldehyde purifier was born, formaldehyde purifier, also known as the formaldehyde purifier, is a kind of deformaldehyde with the function of air purifiers, so formaldehyde purifier in addition to formaldehyde methods have! What are the methods?
1. Mechanical filtration
The use of special filters with formaldehyde function, through direct interception, inertial collision, Brown diffusion mechanism, and screening effect of four methods to capture formaldehyde particles, this method of fine particles collection effect is good but the wind resistance is large, the need for dense filter and regular replacement of the filter.
2. Adsorption
The use of a large surface area and porous structure of the material to capture gas pollutants has a significant removal effect. However, the disadvantage is that the pollutants' particles are large, and it is easy to cause internal blockage.
3. Electrostatic electret filtration
Electrostatic electret filtration can effectively block the air greater than 0.1-micron particle pollutants.
4. High voltage electrostatic dust collection
The use of a high-voltage electrostatic field to make the gas ionization, so that the pollutants dust particles charged adsorption to the electrode on the dust collection method, wind resistance is small, but the larger particles and fibers capture the effect is poor, will cause a discharge, and cleaning trouble time-consuming, easy to produce ozone, the formation of secondary pollution.
5. Negative ions and plasma method
By charging the particles in the air, they aggregate to form larger particles and precipitation. But the particles are not removed; they are just attached to the nearby surface. Not timely removal will lead to dust again.
Deformaldehyde purification machine to remove the formaldehyde effect?
In addition to formaldehyde purification machine with a standard HEPA filter and efficient de-formaldehyde molecular sieve, coupled with negative ion purification, can make the purification ability go one step further, based on activated carbon as the main, potassium permanganate, cold catalysts, and other catalysts as a supplement, formaldehyde and other harmful chemical gases adsorption, and decomposition into organic compounds and water-dense tissue structure, is to have a certain effect of deformaldehyde.
However, it should be noted that in addition to the formaldehyde purification machine addition, aldehyde's ability to look at its cartridge and filter, an ordinary air purification cartridge can not be in addition to formaldehyde, addition formaldehyde cartridge can play in addition to the formaldehyde effect, but also only an auxiliary role, it is a greater role is to speed up air circulation, if the home of formaldehyde pollutants are less, the concentration of lower, with formaldehyde purification machine can be; but if the contaminants are more concentration is higher, the formaldehyde purification machine alone will have some effect. Relying on a formaldehyde purification machine alone is not so effective, but also needs to assist other deodorization methods.
