5 thoughts on “What is the principle of air purifier?”
Velma
Common air purification methods: [Physical purification method] 1. Adsorption filtration -activated carbon n activated carbon is a porous carbon -containing substance. The porous structure provides a large number of surface orientation, which can fully contact the gas (impurities), which gives the active carbon unique adsorption properties, making it very easy to achieve the purpose of absorbing impurities. Just like magnetic force, all molecules have mutual gravity Disadvantages: Ordinary activated carbon cannot adsorb toxic gases, which are low -efficiency and easy to adhere to.
2. Mechanical filter hepa (High Air Filter), Chinese means high -efficiency air filter, reaching the HEPA standard filter, the effective rate of 0.3 microns reaches 99.998%. The Hepa network is characterized by air that can pass, but small particles cannot pass. The HEPA filter is composed of a stack of continuous sub -folding sub -glass fiber membrane, forming a wave -shaped pad to place and support the filtering quality.
[Static electrostatic purification method] Profting the principle of high -voltage static adsorption dust removal. Static electrostatic is a working principle of high -voltage static absorption of dust removal. Under the action of high -voltage electrostatic, the cathode line in the electrostatic field generates electrical discharge, and a large amount of negative ions are generated in the electrical layer. Under the action of the electrostatic field, negative ions are constantly moving towards anode. When the dust in the air passes through the electric field, the dust is charged with the collision of the negative ion. The dust after the charge is also affected by the electrostatic field. Disadvantages: Remove the dust (cannot remove the poisoning gas), the efficiency is lower and slower than the mechanical type, and it is easy to produce ozone. This model is rated as the worst purifier by the US market.
[Chemical purification method] 1 photocatalytic method working principle: When air is catalyzed by photocatalytic air purification device, the photocatalyst does not afford to change under the illumination of light, but it can promote it, but it can promote Harmful substances in chemical reactions, such as formaldehyde, benzene, degradation under the action of photocatalytic, generate non -toxic and harmless substances, and bacteria in the air are also removed by ultraviolet light, so the air is purified. Disadvantages: broad -spectrum but low air flow rate, slower purification speed, and certain radiation to the human body. It is a purification method that is eliminated in Europe and the United States.
2. Formaldehyde clearance agent Purament: It is to use chemicals and formaldehyde for chemical reactions to achieve the purpose of removing formaldehyde 1, chemical reactions: chemical reactions with formaldehyde He water, such as ammonia water, etc.; 2, biological: made of biological agents that can react with formaldehyde, such as urea, soy protein, amino acids, etc.; Such as aloe vera, tea extract, etc.; 4, closed class: made of film formation substances, forming a layer of film to prevent formaldehyde release, such as a few butanose, liquid paraffin, etc. The substances generated after that are likely to bring secondary pollution. The phenomenon of secondary test exceeding the standard in the practice process is that the second is to absorb formaldehyde without changing the chemical composition and reduce the formaldehyde content in the air. To cure the root cause, formaldehyde is easy to release again.
3. Pharmacy, catalytic method Puct: Cold Catalyst, also known as natural catalyst, is another new type of air purification after the light touch media removal air purification material Materials can have a catalytic reaction under normal temperature conditions. Under normal temperature and normal pressure, a variety of harmful and delicious gas is decomposed into harmless and tasteless substances. Patthorm, toluene, tvovov and other harmful gases are generated to generate water and carbon dioxide. During the catalytic reaction process, the cold catalyst itself does not directly participate in the reaction. Cold Cataracts itself is non -toxic, non -corrosive, and non -combustion. The reaction generics are water and carbon dioxide, which does not produce secondary pollution, which greatly extend the service life of adsorption materials.
[Other purification methods] 1. Washing method In the principle of siphon and centrifugation, the purification agent mixed in the water inhale through the siphon principle into the lower part of the coaxial turbine of its motor base through the rade principle In the straw, through the high -speed rotation of the polar motor of the communication cover, and then using the principle of centrifugation, the mixed water purification agent is sprayed into the bottle bile to form a layer of water film, the dust and bacteria in the air are inhaled into the water. At the same time, it will be purified. The air blows into the room, quickly and effectively removes toxin, dust, smoke, odor, virus, etc. in the room, and produces a large amount of fresh oxygen. 2. The negative ion method After contact with the harmful gas floating in the air, the hydroxyl -based ion can restore the active oxygen (oxygen free radical) generated by the atmospheric pollution, nitrogen oxide, cigarettes, etc., and reduce too much reduction Active oxygen is harmful to the human body; the air with a normal electricity with electricity has no charge and settle down, so that the air is purified.

Pay content for time limit to check for freenAnswer 1, the main principle of passive suction filter -type passive air purifier is: using a fan to pump the air into the machine, and filter the air through the built -in filter, which can mainly play the role of filtering dust, odor, toxic gases and killing some bacteria. Essence The filter is divided into: dust filter, de -formaldehyde filter, deodorizing filter, HEPA filter, etc. Among them, the high cost is the HEPA filter. It has a very obvious effect of filtering particles, and it can decompose toxic gases and sterilization effects, and can inhibit secondary pollution of air. The quality of such products and filters determines the effect of air purification. The location of the machine and the indoor layout will also affect the purification effect. 2. The fundamental difference between the principle of actively release the principle of purification and active air purifier and passive air purification is that the active air purifier gets rid of the restrictions of the fan and the filter. In the device, filtering and purification, but effectively and actively release the purification sterilization factors to the air. Through the characteristics of the air spread, the air purification without dead angles in all corners of the room. The technology of purifying sterilization factors in the market mainly includes silver ion technology, ion ion technology, low -temperature plasma technology, optical catalyst technology and net ion ion ion technology. 3. Dual purification (active purification passive purification) combines passive purification technology with active purification technology. The existing filter can be pumped into the air to adsorb harmful substances, but also actively release the purification sterilization factors.
