Problems solved by technology

Although the adsorption method is simple and easy to promote, it can only temporarily absorb a small amount of pollutants. Due to the adsorption saturation state of the adsorption medium, the adsorbed pollutants may dissociate and re-enter the air, causing secondary pollution.
Moreover, the adsorption medium needs to be replaced regularly, so it is very inconvenient in actual use.

Embodiment 1

[0031] The invention provides an air purification medium unit, an air purification device and an air purification method. The air purification media unit of this embodiment includes an upstream filter unit A, a midstream adsorption-desorption unit B, and a downstream photocatalytic unit C, such as figure 1 Shown.

[0032] Preferably, the filter unit A includes a coarse-efficiency filter 2, a HEPA high-efficiency filter 3, and an electrostatic electret filter 4 in sequence in the air flow direction. The coarse-efficiency filter 2 is also called primary filter, coarse dust filter, pre-filter, fresh air filter, etc. The filter material is made of high-quality polyester synthetic fiber PET (non-woven coarse-effect filter cotton); Usually use moisture-proof and water-resistant virgin wood fiber cardboard, which is light in weight, easy to install, and has a smooth and beautiful appearance; the internal filter material adopts a combined inner frame compression design or bonding technol...

Embodiment 2

[0040] In this embodiment, an air purification device is provided, such as figure 1 As shown, the air purification device includes the air purification medium unit, and the air purification device further includes an intake pipe 1 connected to the filter unit A and an air inlet pipe 1 connected to the photocatalytic unit C. The desorption pipe 9 and the gas outlet pipe 10 are connected to the indoor environment.

[0041] Preferably, the thickness of the adsorption medium layer 6 in the adsorption-desorption unit B is 10-20 mm.

[0042] Preferably, a high-power fan 100 and a low-power fan 200 are respectively provided in the desorption pipe 9 and the air outlet pipe 10. Among them, according to the size of the air purification area, the power of the high-power fan is selected to be 50-300W, the power of the low-power fan is 20-100W, and the actual power of the high-power fan is greater than the actual power of the low-power fan. .

[0043] The specific working process of the air pur...

Embodiment 3

[0053] The invention also provides a method of using and processing the air purification device; figure 1 As shown, in this embodiment, the specific steps are as follows:

[0054] A. Open the control valves in the air inlet pipe 1 and the air outlet pipe 10, and open the low-power fan 200 in the air outlet pipe 10, close the control valve of the desorption pipe 9, and take in source air from the outdoor or indoor through the air inlet pipe 1 The air purification device.

[0055] Among them, for above-ground building facilities, the source air can be indoor or outdoor air; for small spaces or places with few people, the source air can be indoor air, and the indoor air is continuously circulated through the air purification device to make the entire place inside The concentration of pollutants is kept at a very low level.

[0056] But for underground construction facilities, because the space is relatively closed, the entire construction facility needs to be ventilated, so the source ...

Abstract

The invention relates to an air purification medium unit, an air purification device and an air purification method. The air purification medium unit comprises an upstream filtering unit, a middlestream adsorption-desorption unit, and a downstream photocatalysis unit. Meanwhile, with the air purification medium unit, the air purification device is designed and a set of the air purification method is formed. By aiming at characteristics of light catalysis and an adsorption method, the adsorption method is combined with photocatalysis, so that activated carbon and activated carbon fiber adsorption and desorption-TiO2 (titanium dioxide) photocatalysis technology becomes an air purification technology with high efficiency and long service life. On the one hand, the activated carbon or the activated carbon fiber is desorbed to be regenerated in situ, thereby reducing the original replacement cycle of a filter element; and on the other hand, the activated carbon or the active carbon fiber is desorbed to provide a high-concentration reaction environment for the photocatalysis of TiO2, so as to accelerate the reaction rate.

Description

Technical field [0001] The invention relates to the field of air purification, in particular to an air purification medium unit, an air purification device and an air purification method. Background technique [0002] Experts at home and abroad have proved that after "smoke-type" and "photochemical smog-type" pollution, modern people are entering the third pollution period marked by "indoor air pollution". Studies have shown that indoor air pollution is two to five times more serious than outdoor air, and can reach 100 times under special circumstances. More than 500 kinds of volatile organic compounds can be detected in indoor air, some harmful gases can be ten times or even dozens of times higher than outdoors, of which more than 20 kinds are carcinogens. According to a data released by the World Health Organization: 100,000 people worldwide die of asthma due to indoor air pollution every year. A survey in the United States showed that more than 500 volatile organic compounds...
