Problems solved by technology

[0005] At present, physical adsorption and other methods are mainly used to remove formaldehyde. For example, activated carbon, bamboo charcoal, etc. are used as adsorbents to adsorb formaldehyde, but the adsorption capacity of the adsorbent is limited, and the removal of formaldehyde is slow and the efficiency is low, and the formaldehyde in the room cannot be discharged in time.

Embodiment 1

[0086] Embodiment 1: The angle between the air circulation fan and the wall where the window is located is θ=0°, C1 and C3 are turned on, and C2 is turned off.

Embodiment 2

[0087] Embodiment 2: The angle between the air circulation fan and the wall where the window is located is θ=45°, C1 and C3 are turned on, and C2 is turned off.

Embodiment 3

[0088] Embodiment 3: The angle between the air circulation fan and the wall where the window is located is θ=60°, C1 and C3 are turned on, and C2 is turned off.

[0089] Testing process:

[0090] Before the room was sealed, the measured indoor temperature was 26.3 degrees, and the relative humidity was 34.3%.

[0091] 1. Select four rooms with similar interior decoration. The rooms are decorated with wooden furniture, sofas, wallpaper on the walls, white latex paint on the ceiling, and wooden floors on the ground.

[0092] 2. Room size: length × width × height = 4.2m × 3.0m × 2.7m, room volume: 34m 3 ;

[0093] 3. Room doors and windows: the size of the window is 3m×1.6m (length×width);

[0094] 4. Before starting the fan, use a formaldehyde detector (Interscan 4160-II formaldehyde analyzer, USA) to measure and record the formaldehyde concentration.

[0095] 6. Choose commonly used sliding windows and turn on the air circulation fan to exhaust the air.

[0096] 7. The ang...

Abstract

The invention provides a method for removing indoor formaldehyde through an air circulation fan. An indoor window is opened, the indoor air circulation fan is opened, and the included angle between the blowing direction of the air circulation fan and the wall face where the window is located is adjusted. Therefore, on one hand, exchange of air at different indoor positions is facilitated; and on the other hand, exchange of indoor air and outdoor air at the window is facilitated, so that indoor formaldehyde is exchanged to the outside as soon as possible. According to the technical scheme, the indoor ventilation quantity can be effectively increased, so that the indoor formaldehyde removal speed and efficiency are improved, and the better formaldehyde treatment effect is achieved.

Description

technical field [0001] The invention relates to the technical field of formaldehyde treatment, in particular to a method for removing indoor formaldehyde. Background technique [0002] With the development of society, people pay more and more attention to air pollution. Relevant data show that indoor air pollution is 5 to 10 times higher than outdoors, and there are as many as 500 kinds of pollutants. Indoor air pollution has become the cause of many diseases, and formaldehyde is a major aspect of indoor air pollution. [0003] According to statistics, modern humans spend more than 80% of their time indoors on average every day. Various decoration materials and furniture used in interior decoration will volatilize harmful substances such as formaldehyde, benzene series and other volatile organic compounds, which will seriously affect people's health. Especially for furniture, because a large amount of adhesive is often used in the board manufacturing process, the toxic an...
