Description

Technical Field

[0001] The utility model belongs to the technical field of indoor air purification, and in particular relates to an active indoor air purification system. Background Art

[0002] People's requirements for the quality of urban living environment are constantly increasing, but the intensiveness of urban buildings is becoming more and more obvious. Most buildings have problems such as limited space and ventilation conditions, uneven air quality, and the use of plane and facade space is subject to many restrictions (for example, the width of public passages cannot be reduced, and various types of table tops and walls in the home need to consider storage functions).

[0003] Indoor air quality has an important impact on the health of the human cardiovascular system and respiratory system. The health burden caused by indoor air pollution has always been a focus of global attention. The main air pollutants of concern worldwide include particulate matter (PM2.5 and PM10), near-ground ozone (O3), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2), lead, cigarette smoke, and carbon disulfide (CS2). At the same time, indoor carbon dioxide CO2, organic volatiles, and biological pollutants (pollen, fungi, etc.) also have an important impact on human health. In my country, the top five disease burdens caused by exposure to indoor air pollutants (IAP) are fine particulate matter (PM2.5), carbon monoxide (CO), radon (222Rn), benzene (C6H6) and nitrogen dioxide (NO2). In the latest national standard "Indoor Air Quality Standard", there are relatively clear standards for air temperature, humidity, wind speed, fresh air volume, chemical pollutants, and radioactive pollutants. For example, the 24-hour average level of PM2.5 shall not be higher than 0.05mg / m3, the 1-hour average level of carbon monoxide shall not be higher than 10mg / m3, the annual average level of radon shall not be higher than 300Bq / m3, the 1-hour average level of benzene shall not be higher than 0.03mg / m3, and the 1-hour average level of nitrogen dioxide shall not be higher than 0.2mg / m3.

[0004] Plants can absorb carbon dioxide and release oxygen, absorb pollutants, regulate temperature and humidity, improve environmental quality, and improve physical and mental health. Different plant species have differences in air purification ability, which can be ten or even a hundred times different due to differences in biological structure, metabolic pathways, etc. It is of great practical value and social significance to select plant species with strong air purification ability, good ornamental effect, and easy survival and management, and apply them to indoor environments in appropriate forms.

[0006] The purpose of the utility model is to provide an active air purification system that does not occupy plane space, so as to improve the indoor air purification efficiency of green plants and solve the problem of occupying plane space and affecting storage or passage. Utility Model Content
