Technical Field

The invention relates to the technical field of air purification, in particular to an indoor formaldehyde purification method.

Background

Formaldehyde is an important industrial raw material, has excellent bonding and corrosion resistance properties, and can strengthen the hardness of plates, so that the formaldehyde is widely used, and particularly, the formaldehyde is used as a binder for artificial plates such as plywood, shaving boards, medium-density fiberboards and the like used in modern interior decoration. Because the boiling point of the formaldehyde is only-19 ℃, the formaldehyde is very easy to volatilize, the volatilization speed of the formaldehyde is accelerated along with the rise of the temperature, the formaldehyde in the artificial board is volatilized for years or even decades, and the volatilized formaldehyde can seriously pollute the indoor air. The formaldehyde has long been identified as the first-class carcinogenic and teratogenic substance by our country and world health organizations. Possible hazards from long term exposure to formaldehyde: respiratory diseases, memory and intelligence decline are caused in mild cases, and even leukemia and various cancers are caused in severe cases, and even death is caused directly, wherein the injury to children is particularly serious.

The current formaldehyde removal method mainly comprises the following steps: (1) an activated carbon method: by means of a large amount of developed pore structures and large specific surface in the activated carbon, formaldehyde molecules are adsorbed on the inner surface of the active carbon pore passage, but the active carbon is weak in adsorption capacity and easy to saturate, and once the adsorption is saturated, formaldehyde desorption can occur to further cause secondary pollution; (2) an ozone oxidation method: the strong oxidizing property of ozone and formaldehyde are used for carrying out chemical reaction to generate carbon dioxide and water, but the ozone is easy to cause damage to human bodies and has strong destructiveness to furniture; (3) the biological enzyme method comprises the following steps: the formaldehyde is decomposed into carbon dioxide and water by means of the combined action of microorganisms and active enzymes, but the formaldehyde is removed by enzyme catalysis in a slow release process, so that the complete removal time is as long as several years, most of the active enzymes have short service lives, the requirements on the temperature and the humidity of the environment are high, the enzymes are easy to inactivate, and the efficient and lasting formaldehyde removal is difficult to realize; (4) photocatalytic oxidation method: the inorganic or composite catalyst such as titanium dioxide with high photocatalytic activity catalyzes and oxidizes formaldehyde in the air under the action of visible light, the safety factor is high, but the catalyst in the form of particles is difficult to disperse and has slow reaction speed, particularly, the formaldehyde can still be continuously released from furniture and fabrics at night when no light exists, and the visible catalyst is difficult to oxidize the formaldehyde due to lack of light energy, so that the purification efficiency is low on the whole.

Therefore, in order to solve the problems of the above methods for removing formaldehyde, there is an urgent need for a method for efficiently and safely removing free formaldehyde from a room.
