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. In the air purification medium unit of the present embodiment, include upstream filter unit A, midstream adsorption-desorption unit B, and downstream photocatalytic unit C, such as figure 1 shown.

[0032] Preferably, the filter unit A includes a coarse filter 2 , a HEPA filter 3 and an electrostatic electret filter 4 sequentially in the air flow direction. Described coarse filter screen 2 is also called primary filter screen, coarse dust filter, pre-filter, fresh air filter etc., filter material adopts high-quality polyester synthetic fiber PET (non-woven coarse filter cotton); Usually use moisture-proof and water-resistant raw pulp 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 technology to ensure the airt...

Embodiment 2

[0040] In this embodiment, an air cleaning device is provided, such as figure 1 As shown, the air purification device includes the air purification medium unit, and the air purification device also includes the air intake pipe 1 connected to the filter unit A and the photocatalytic unit C connected to the The desorption pipeline 9 and the gas outlet pipeline 10, the gas outlet pipeline 10 communicates with 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 arranged in the desorption pipeline 9 and the gas outlet pipeline 10 . Among them, according to the size of the air purification area, the power of the high-power fan is 50-300W, and the power of the small-power fan is 20-100W. The actual power of the high-power fan is greater than the actual power of the small-power fan. .

Embodiment 3

[0053] The present invention also provides a use and treatment method of an air purification device; figure 1 As shown, in this embodiment, its 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 enter the air from the outdoor or indoor suction source through the air inlet pipe 1 The air cleaning device.

[0055] Among them, for above-ground building facilities, the source air can be indoor or outdoor air; for a small space or a place with few people, the source air can be indoor air, and the indoor air is continuously circulated through the air purification device, so that the whole place Concentrations of pollutants are kept at a very low level.

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

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] Research by experts at home and abroad has proved that after "soot 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 worse than outdoor air, and can reach 100 times in special cases. More than 500 kinds of volatile organic compounds can be detected in indoor air, and some harmful gases can be ten times or even dozens of times higher than outdoors, and more than 20 kinds of them are carcinogens. According to a data released by the World Health Organization, 100,000 people in the world die of asthma every year because of indoor air pollution. A survey in the United States shows that more than 500 kinds of volatil...
