Commonly used air purification technologies
Commonly used air purification technologiesI. Activated carbon adsorption technology1、Principle: This technology uses the high specific surface area of activated carbon to chemically adsorb harmful substances in the air, thus purifying the pollution, and has a good effect on the purification of volatile organic substances and odors. 2, advantages and disadvantages: in a short period can effectively adsorb pollutants, but with the increase in air temperature and wind speed, the adsorbed pollutants may be free out, again into the air, easy to form secondary pollution. Therefore, the advice of experienced people is to try to use it in places where pollution is more concentrated to solve part of the pollution problem. II. Air freshener 1、Principle: This method is mainly to release a high concentration of fragrance in the air to cover up other odors. 2, advantages and disadvantages: contains fragrance, spices, and other substances can mask the odor in the air, from the olfactory aspects of the solution to the problem of pollution. But its role is only to cover up only, the removal of pollutants, and bacteria and has little effect; its own has a certain degree of toxicity, especially the inferior quality of the product more serious. Therefore, the advice of experienced people is to minimize the use, or not use. III. Formaldehyde remover 1, the principle: through the chemical reaction to remove indoor formaldehyde pollution, generally in the form of a spray, in the air or emit pollution of furniture, door frames, and other places in the front and back of the multifaceted spray. 2, advantages and disadvantages: the use of chemical components to reduce and reduce the pollution of formaldehyde to some extent, the removal of wooden products is particularly effective. The disadvantage is that only for formaldehyde treatment and has no role for benzene, ammonia, bacteria, and so on, and the sustained effect is not strong, for the latent pollution has no role; In addition, the product itself also has a certain degree of toxicity, whether for furniture or the human body have a certain degree of harm, should not be used for a long time. IV. Negative ion purification technology 1、How to use: brand new technology, as long as the equipment can be placed in a polluted environment. 2, advantages and disadvantages: the role of high pressure releases a certain amount of negative ions, combined with the air pollutants so that pollution gradually gathered, sedimentation, the effect is more obvious, the use of relatively simple. The disadvantage is that the purification process is relatively slow, and in the process of use is also easy to accumulate dust, causing damage to the equipment, so also according to the corresponding situation to choose to use. |
