Problems solved by technology

In the face of these two important pollutants, traditional indoor air purification equipment can only achieve a single purification function, that is, it can only adsorb formaldehyde in the air but not PM2.5, or can only remove PM2.5 Particles cannot remove formaldehyde. For the current harsh and complex indoor air pollutants, the research on practical solutions is urgent

Abstract

The invention discloses a carbon-fiber indoor air purifier and a preparation method thereof .The carbon-fiber indoor air purifier comprises a PM2.5 micro-particle adsorption device, a formaldehyde photocatalytic degradation device and an atomizing air humidification device, and the formaldehyde photocatalytic degradation device is located between the PM2.5 micro-particle adsorption device and the atomizing air humidification device; the PM2.5 micro-particle adsorption device comprises a PM2.5 micro-particle adsorption layer which is composed of two surface filter layers made of thermoplastic fiber fabric and a micro-particle pollutant adsorption layer located between the two surface filter layers; the formaldehyde photocatalytic degradation device comprises a degradation layer and ultraviolet lamp light sources located on at least one side of the degradation layer, and the degradation layer comprises a carbon fiber carrier fabric and a nano-titania coating coating on the surface of the carbon fiber carrier fabric .According to the indoor air purifier, the API value of final purified indoor air is below 50, the indoor air humidity ranges from 45% to 65%, and formaldehyde emission in per cubic meter of the indoor air is lower than 0.07 mg in a closed indoor environment.

Description

technical field [0001] The invention relates to a carbon fiber indoor air purifier and a preparation method thereof, in particular to a multifunctional indoor air purifier using an activated carbon fiber fabric adsorption layer and a nano-titanium dioxide coating composite carbon fiber fabric photocatalytic degradation layer. The purifier can be used Effectively remove PM2.5 pollutants and formaldehyde pollutants in indoor air, purify indoor air, and improve indoor air quality. Background technique [0002] In recent years, with the rapid development of the economy, the emphasis on transportation and heavy industry has increased, which has brought about a sharp increase in the emission of urban pollutants, posing a fatal threat to air quality. At present, my country's large and medium-sized cities continue to appear smoggy weather, the chief culprit of which is PM2.5 pollutants. PM2.5 has had a great impact on our lives, and as the air quality continues to deteriorate, PM2....
