technical field

The invention relates to the field of air purification, in particular to a domestic air purification green biological filter bed device.

Background technique

In recent years, China's air pollution problem has become one of the most serious environmental problems. For example, many areas in mainland China are facing the hazards of inhalable particulate matter, especially in the Beijing-Tianjin-Hebei region and the Yangtze River Delta region. The particulate matter often forms a large area of dust. Hazy weather. Sulfur dioxide pollution is also severe. In addition, the northwest region also suffers from severe sand and dust pollution. Because the soil in the south is acidic, the emissions of sulfur dioxide and nitrogen oxides are huge, and the area of acid rain affects almost 1/3 of the country's land. The problem of air pollution has become a normal state of urban life and has an impact on people's healthy quality of life.

Under the background of large-scale ecological environment governance, urban residents who take the family as the unit also began to subjectively seek better air quality, so as to improve the living environment and quality of life of the family. Therefore, the improvement of the environment and the purification of the air are no longer purely an act of the government, but are gradually transforming into a kind of spontaneous green action by every household. The people's growing demand for air quality stimulates industrial-scale purification technology and To the scale of the family. The popularization, dailyization, and daily life of air purification have made the introduction of purification technology into ordinary people's homes an eye-catching issue. This is not only a reflection of social development at the level of people's material needs, but also the development trend of environmental improvement as a national movement.

Existing indoor air purification devices are roughly divided into two types:

1. Through the cultivation of indoor green plants, the residents can nourish the indoor air through the photosynthesis of the leaves of the plants themselves, purify the air, absorb the dust in the indoor air, or pass the air through the root system of the plants through the purification device to carry out biological decontamination.

2. Based on the proportion of physical and chemical fillers, let the air pass through a special air purification device, and let the fillers perform a complete gray purification treatment on the passing air.

Traditional indoor air purification devices mainly rely on blades to absorb suspended particles and harmful substances, and release oxygen to improve the air or use physical and chemical fillers to adsorb harmful substances and particles in the air. Although existing indoor air purification devices can also improve air quality to a certain extent, they cannot combine efficient purification technology with green and environmentally friendly biological filter beds.
