Movable efficient formaldehyde removing and air purification device

Abstract

The invention discloses a movable efficient formaldehyde removal and air purification device, which comprises a case, a case door, an air inlet, a filter cartridge, an air outlet, a base and a controlsystem, wherein the air inlet is formed in the side surface of the case, the air outlet is formed in the upper portion of the case, the control system is arranged at the bottom of the case, a drivingdevice is arranged on the base, and the filter cartridge is arranged in the case, is of a multi-layer structure and comprises a filter layer, an adsorption layer and a decomposition layer. By adopting a purification mode of multi-stage filtration, active carbon adsorption and decomposition of formaldehyde with manganese-based oxide, solid and gas pollutants in air can be efficiently purified at the same time, and formaldehyde is thoroughly decomposed into carbon dioxide and water; the air purifier can automatically move to purify multi-area air through movable and infrared induction so as toachieve the effect of one-machine multi-room and multi-area circulating continuous purification; and the movable efficient formaldehyde removal and air purification device is high in air purificationefficiency, good in formaldehyde removal effect, simple in structure, economical, environmentally friendly and suitable for productization and large-scale application and popularization.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a mobile high-efficiency formaldehyde-removing air purification device. Background technique [0002] With the increasingly serious environmental pollution, coupled with the pollution of many interior decoration and decoration materials, air quality has aroused widespread concern in society. 68% of human diseases are related to air pollution; the World Health Organization lists indoor air pollution as the first of 18 types of carcinogens. Formaldehyde is recognized as a highly toxic substance, which is extremely harmful to human health, especially to infants, pregnant women, the elderly and other groups with high sensitivity to formaldehyde. According to the investigation of indoor household pollution, the indoor formaldehyde pollution in newly decorated rooms generally exceeds the standard, and people who stay in the environment with severe formaldehyde pol...

AI Technical Summary

Problems solved by technology

Activated carbon has good adsorption properties for non-polar substances of benzene series, but it has poor adsorption retention for polar molecule formaldehyde, and it is easy to release the adsorbed formaldehyde and other substances into the air again when changing indoors, so activated carbon cannot be effective. Remove formaldehyde in the air by adsorption; glass fiber is the main filter material used in HEPA (high-efficiency air filter), which is used to capture particulate dust and various suspended solids below 0.5um, but it is harmful to formaldehyde and other polluting gases. Absorption has no obvious effect; photocatalyst materials need to be illuminated or used in conjunction with ultraviolet lamps, which not only consumes a lot of energy, is expensive, is easily affected by environmental factors, and long-term use of ultraviolet light also has potential harm to the human body

[0004] In addition, most of the existing formaldehyde-removing air purifiers are fixed, and the air can only be purified in a fixed position. If the air in other areas needs to be purified, it needs to be transported manually or in a closed environment for a long time achieve indoor air circulation

A small number of air purifiers add mechanical wheels at the bottom. Although it provides convenience for handling, it does not fundamentally improve the working efficiency of the air purifier.
