Now the air quality is getting worse and worse, with the development of heavy industry more and more rapidly, air pollution has been quite serious, especially after watching the Chai Jing published "under the dome" video, we may be afraid of, not only when the haze we will absorb the toxic gases in the air, usually the air also contains harmful substances. Containing harmful substances, so air purification equipment is increasingly needed. So what are the air purification equipment?
What are the air purification equipment
Air purification equipment is also known as "air cleaning equipment" or air freshener, is used to filter out pollutants in the air, or kill airborne bacteria, can effectively improve air quality products. Air purification equipment in different areas have different types, according to the field classification can be divided into: household air purification equipment, vehicle air purification equipment, and medical air purification equipment, industrial air purification equipment, etc., at present the main household and commercial air purification equipment.
Household air purification equipment role
Can absorb, filter dust, odor, and formaldehyde, etc., which are decoration pollution, the impact on human health. Negative ions can improve air quality, purify the air, known as "air vitamins", has a very important impact on the human body. If you breathe the right amount of negative ions every day, you can effectively reduce blood pressure, enhance the heart, lung function and other functions, so that the cerebral cortex activity function. Negative ions can also quickly neutralize the air in the coke smoke, second-hand smoke, etc., play a role in purifying the air, general household air purification equipment are applied to, can effectively solve the problem of indoor air pollution.
Commercial air purification equipment applications
Commercial air purification equipment is generally used in industry, engineering, it can be filtered to remove larger particles in the air, in order to prolong the cleaning time of the electrostatic adsorption device, which is also its principle of operation. Electrostatic adsorption device equipment can not only adsorb larger particles in the air, but also can adsorb tiny particles in the air, tiny particles in the air through the electrostatic adsorption device will be positively charged, and then will be the negative electrode of the dust collection sheet firmly adsorbed, so that after a certain period of time to clean it can be removed from the particulate matter. Commercial air purifier also uses the principle of activated carbon, through the activated carbon filter air, can remove the harmful gases of ammonia, formaldehyde, etc., to exclude healthy air. Commercial air purification equipment is also used in the ultraviolet high-tech technology, the use of ultraviolet radiation, kill a variety of microorganisms in the air, effective decomposition of harmful gases, after layers of filtration, the size of the particles in the air and the harmful gases will be removed, will be able to ensure that as far as possible, people breathe healthy air.
The value of implementing air purification:
1. Through the comprehensive treatment of indoor pollution sources such as walls, ceilings, carpets, curtains, sofas and storage cabinets that can effectively decompose formaldehyde, benzene and other organic pollutants.
2. Improve indoor air quality. purification products have deodorant, mildew, antibacterial, long-lasting purification of air properties, can purify the air, remove odors, to prevent the spread of germs, can effectively solve the problem of indoor air pollution, eliminate the adverse effects of indoor air pollution and affect people's mood.
3. Reduce daily drudgery. Due to the deterioration of indoor air quality, the frequent use of air freshening products, aromatics, disinfectants, etc., not only increases the cost of daily expenses can also cause secondary pollution.
Classification of air purifiers
Filtration type. This type of air purifier utilizes porous filter material to trap and collect particles suspended in the air. It generally uses HEPA filters or activated carbon filters, which can play a role in filtering tiny particles and adsorbing harmful gases such as formaldehyde, benzene and ammonia. If the indoor air is not particularly dirty, according to the average use of 6-8 hours a day, the service life of the activated carbon is only about 6 months, the filter must be replaced. Nowadays, most purifiers also have a replacement cartridge indicator, if you do not replace it in time, the purifier will not work as it should. In addition, these purifiers generally have multi-layer filtration, pay attention to the maintenance of the filter will not be reversed, otherwise it will affect the purification effect, reduce the service life.
Electrostatic type. Electrostatic air purifier with thousands of volts of high voltage inside, can be ionized to make particles charged, and then be adsorbed. Therefore, when buying such products, be sure to check the product certification or the National Household Electrical Appliances Quality Supervision and Inspection Center issued by the qualified inspection report, so as to avoid danger due to unqualified product quality. In general, the dust collection plate of such air purifiers are relatively sharp pieces of metal, easy to scratch people when cleaning, not recommended for the elderly.
Photocatalytic type. Because the photocatalyst can only play the role of catalyst, itself does not participate in the chemical reaction, so the effect of photocatalyst air purifier is more durable. This kind of product cleaning and maintenance is more convenient, middle-aged and elderly people can choose. Since the photocatalyst must be catalyzed by light to produce a reaction, when using, do not cover the photocatalyst material or the light source designed to irradiate the material.
Negative ion type. Negative ion devices produce a certain amount of ozone while generating negative ions. If the concentration of ozone is too high, it may be hazardous to health. So when consumers buy air purifiers with negative ion function, they should pay attention to the ozone concentration produced by the machine should not be too high. One is to use the nose to smell, if the irritating odor is very heavy, meaning that the ozone concentration may exceed the standard; the second is to check whether the inspection report is qualified. Consumers with a history of allergies should try to avoid such products.
Ultraviolet type. Excessive ultraviolet light can cause photochemical reactions, which can cause a series of changes in human function, especially harmful to the skin, eyes and immune system. Therefore, when buying and using such products, it should be noted that there should be no UV light leakage, that is, you can not see the lamp exposed, so as not to bring harm
Air purifiers play a big role in our health, to help us purify the air to maintain a clean living environment, personal advice or try to buy an air purification equipment to avoid breathing unhealthy air, and to do the appropriate measures when you go out.
The above is about what air purification equipment, I hope it can help you!
