Description
Technical Field
The invention belongs to the technical field of air purification, and particularly relates to a movable efficient formaldehyde-removing air purification device.
Background
With the increasing severity of environmental pollution, coupled with the pollution of many interior and decorative materials, air quality has attracted widespread social attention. 68% of human diseases are associated with air pollution; the world health organization lists indoor air pollution as the first class of 18 carcinogens. The formaldehyde is a well-known strong toxic substance, has great harm to human health, and particularly has great harm to high-formaldehyde-feeling crowds such as infants, pregnant women and the old. According to the investigation on indoor household pollution, the indoor formaldehyde pollution degree of a newly-decorated room generally exceeds the standard, and people are in a severe formaldehyde pollution environment for a long time and are easy to cause respiratory diseases such as lung cancer, laryngeal cancer and the like; when the formaldehyde content reaches 30mg/m3And the life safety of people is threatened. Therefore, the problem of formaldehyde pollution in indoor air caused by room decoration is not easy to solve.
At present, the indoor formaldehyde pollution is mainly treated by adopting an air purifier. For the air purifier, the effective purification of formaldehyde in the indoor air is mainly realized by the filter element material. At present, the filter element materials in the air purifier mainly comprise active carbon, glass fiber, photocatalyst and the like. The activated carbon has good adsorbability to nonpolar substances of benzene series, but has poor adsorbability and retentivity to polar molecular formaldehyde, and easily releases adsorbed substances such as formaldehyde into the air again when the indoor changes, so the activated carbon cannot effectively remove the formaldehyde in the air by an adsorption method; the glass fiber is a filtering material mainly adopted in HEPA (high efficiency air filter), is used for trapping particle dust and various suspended matters below 0.5um, and has no obvious effect on absorbing pollution gases such as formaldehyde and the like; the photocatalyst material needs illumination or is matched with an ultraviolet lamp for use, so that the photocatalyst material is high in energy consumption and cost and is easily influenced by environmental factors, and the ultraviolet light used for a long time also generates potential harm to human bodies.
In addition, most of the existing formaldehyde-removing air purifiers are fixed, air can be purified only at fixed positions, and if air in other areas needs to be purified, indoor air circulation needs to be achieved through manual transportation or a long-time closed environment. Mechanical wheels are added on the bottom of a small part of air purifiers, so that convenience is provided for carrying, but the working efficiency of the air purifiers is not improved fundamentally.
