Air purifier with gas exchange function and capable of treating formaldehyde and PM2.5 completely

Abstract

The invention discloses an air purifier with a gas exchange function and capable of treating formaldehyde and PM2.5 completely. The air purifier comprises nine passes of treatment facilities of a metal wire separation net or a plastic separation net, a rough non-woven film, a fine non-woven film, a coconut shell active carbon fiber film, a bamboo active carbon fiber film, a deep-frequency ultraviolet lamp, a nano-Pt/TiO2 ceramic honeycomb sieve plate net, a HIMOP fast purification ceramic particle interlayer and a ePTFE teflon non-woven multi-micropore composite film. Sensors are further arranged at an air inlet and an air outlet of the air purifier correspondingly. According to the air purifier, the nine passes of filter screens and filter materials are adopted for purification treatment, and thus dust and pollen in air, germs, chemical pollutants, PM2.5 particulates and other various air pollutants can be treated.

Description

technical field [0001] The invention relates to an air purifier, in particular to an air purifier with a ventilation function for completely treating formaldehyde and PM2.5. Background technique [0002] With the development of industry, all kinds of enterprises in our country are increasing continuously. While the number of enterprises is increasing, there is no doubt that the emission of waste gas and waste residue in the process of industrial production has also increased, so it has caused huge pollution to the air, especially in northern my country. Especially in the Beijing-Tianjin-Hebei region. [0003] At present, according to relevant statistics, adverse weather conditions such as smog and heavy pollution in the Beijing-Tianjin-Hebei region have accounted for more than 60% of the year, which has seriously affected people's daily life and health. The reason is that the main factors affecting the air quality are as follows according to the testing situation: firstly, a...

Problems solved by technology

[0006] At present, some air purification products have the following defects: using water treatment and liquid treatment technology, if the water is changed when using this technology, if the liquid is not changed in time, it is easy to breed bacteria and secondary pollution caused by mold, and the noise of the water flow is too large during operation, causing noise Pollution

[0007] Using electrostatic precipitator technology, when using an electrostatic precipitator, the surface of the cathode and anode is easy to absorb a large amount of dust, which will affect the purification effect of electrostatic precipitator, and it is easy to produce ozone pollution when the design is improper, and it has basically no effect on harmful gas pollution.

[0008] Ozone technology is used, because the concentration of ozone is too high due to improper control. Excessive ozone is seriously harmful to human health and has a certain corrosive effect on households, office equipment and buildings.

Negative ion purification technology. Negative ion is a kind of air ion with negative charge. Negative oxygen ion can improve lung function and give people a relatively fresh feeling in a short time, but its life is very short, and ozone may be generated at the same time, forming secondary pollution , cannot decompose organic pollutant gases

[0009] HEPA membrane filtration technology is also the most widely used PM2.5 removal technology on the market. It is known as the most advanced technology in the world, but it has the following fatal flaws: a. The pore size of the HEPA membrane filter is above 0.3 microns, and PM2.5 refers to the diameter 0.25 microns, so there is basically no processing capacity for PM2.5 particles; b, general viruses are smaller than 0.3 microns, so the HEPA membrane can only isolate 0.3 microns of bacteria, reduce the amount of bacteria, and the filter has a large wind resistance, and the membrane can also become a breeding ground for bacteria hotbed; c, HEPA has no ability to deal with harmful chemical gases
