Problems solved by technology

But its disadvantage is that the amount of purifiers such as ozone and hydroxyl group designed by the air purifier is small, and the bactericidal effect is not obvious; and after long-term use, dust will cover the titanium dioxide and reduce its photocatalytic function, thereby affecting the effectiveness of air purification. Sexuality and stability, maintenance is also inconvenient
In addition, due to the low air volume, the air purifier is only suitable for small rooms, and the effect is not obvious for vehicles and large rooms

Embodiment 1

[0030] The air purification equipment of the present invention with structure as shown in Figure 1 is installed in the car and the area is about 27m 2 In the public bus (Shanghai AK8061), the method described in GB / T18204-2000 is used for detection. Among them, the dual-frequency ultraviolet purification equipment is a dual-frequency ultraviolet tube with radiation wavelengths of 185 nanometers and 254 nanometers; the photocatalytic material is titanium dioxide; the piezoelectric thermoelectric material is composed of 90wt% tourmaline and 10wt% topaz. It is measured that the average number of bacteria in the car before using the air purification equipment (between 20:50 and 21:00) is 150 / cubic meter, and after 7 hours of use (between 4:33 and 4:42) The average number of bacteria is 9 / m3.

[0031] This result shows that the air purification equipment of the present invention has a good bactericidal effect.

Embodiment 2

[0033] The air purification equipment of the present invention with the structure shown in Figure 3 is installed in a biomedical laboratory, and the method described in GB / T18204-2000 is used for detection. Among them, the dual-frequency ultraviolet purification equipment is a dual-frequency ultraviolet tube with a double-tube structure and a radiation wavelength of 185 nanometers and 254 nanometers; the photocatalytic material is nano-scale titanium dioxide; the piezoelectric thermoelectric material is tourmaline. It is measured that the average number of bacteria in the laboratory is 1100 / cubic meter before using the air purification equipment, and the average number of bacteria in the laboratory is 190 / cubic meter after 2 hours of use.

[0034] This result shows that the air purification equipment of the present invention has a good bactericidal effect.

Embodiment 3

[0036] In the meeting room (testing location 1) and office area (testing location 2) of Room 3304, Shanghai Jiahua Central Plaza, and the two offices (testing location 3 and testing location 4 respectively) at 01B, 29th Floor, No. 989 Changle Road, Shanghai, according to The air cleaning equipment of the present invention having the structure shown in FIG. 1 is installed as shown in FIG. 4 . Among them, among the air purification equipment tested at testing locations 1 and 2, the dual-frequency ultraviolet purification equipment is a dual-frequency ultraviolet tube with a radiation wavelength of 185 nm and 254 nm; the photocatalytic material is nano-scale titanium dioxide; the piezoelectric thermoelectric material is composed of Composition of 80wt% tourmaline and 20wt% quartz. Among the air purification equipment tested on testing sites 3 and 4, the dual-frequency ultraviolet purification equipment is a dual-frequency ultraviolet tube with a radiation wavelength of 185 nm and...

Abstract

The invention provides an air purification equipment, the equipment comprising double frequency ultraviolet purification equipment, piezoelectricity pyroelectricity purification equipment and photocatalytic purification equipment. By comprehensivly utilizing purification techniques, the equipment kills microorganisms such as bacteria, mould and virus, and simultaneously effectively removes a variety of contaminants such as volatile organic compounds(VOC), formaldehyde, benzene, ammonia, suspended particles in air and dust mite with stronger adaptability. The invention also provides a method for purifying air, an air purification system equipped with the obove air purification equipment and the use thereof.

Description

technical field [0001] The invention relates to the field of air purification, in particular, the invention relates to an air purification device, an air purification system equipped with the device and its application. Background technique [0002] The development of urbanization makes indoor life and work occupy more than 80% of people's time. With the improvement of living standards and the concern for personal health, the requirements for indoor air quality are also increasing. The World Health Organization and governments of various countries have also assessed the health impact of indoor air pollution in the past ten years, and warned that in the next few decades, indoor air pollution will become an important "killer" of personal health. The avian flu that occurred in 1997, the SARS that broke out in 2003, and the influenza that often occurred during autumn and winter are also closely related to the air quality in indoor and public places such as transportation vehicl...
