Description
Technical Field
The invention relates to the technical field of air purification, in particular to an adsorption device and method for organic volatile gas.
Background
The air purification is to provide the whole solutions of sterilization, dust reduction, haze removal, removal of harmful decoration residues, peculiar smell and the like aiming at various indoor environmental problems, improve the living and office conditions and promote the physical and mental health. The indoor environmental pollutants and pollution sources mainly comprise radioactive gases, mould, particles, decoration residues, second-hand smoke and the like
Along with the increasing severity of air pollution, people are more consciously aware of the harm of organic volatile gases such as formaldehyde, benzene, xylene and the like. The air purification action has been highly regarded by people. Tracing to the source, we first found the source of the release of benzene, xylene, formaldehyde in the home or in the public: various decorative sheets, furniture, and the like.
With the gradual realization of the well-off life, people have higher requirements on the quality of the home environment, and the home decoration becomes fashionable. However, people often neglect the influence of the decorated living room environment on health and safety. The wardrobe, the drawer and the like are the formaldehyde release sources and are places with relatively high formaldehyde concentration. Reducing the formaldehyde concentration in these locations is most effective in reducing the concentration throughout the room.
Because the air is not circulated relatively at the positions of the wardrobe, the drawer and the like. Therefore, the simple placement of plants or charcoal bags can not effectively absorb the organic volatile gases such as formaldehyde, benzene, xylene and the like in the places such as wardrobe, drawer and the like where the air is relatively not circulated.
