SiO_2 Adsorption Aerogel Odor Dissipation Control Technology Based on Active Purification Technology

摘要

As the use of automobiles increases, people spend more time in the car, and the air quality inside the vehicleis receiving more and more attention. Due to the large use of organic chemical materials in automotivedecorative materials, it is easy to produce a variety of toxic and harmful volatile compound gases, which wouldcause the odor inside the car to affect the health of the driver. The unique nano-porous structure of SiO2aerogel gives it excellent adsorption properties. Therefore, in this paper, the concentrations of the CO, PM2.5and TVOC under different road environments and driving conditions are detected and analyzed, based on theactive purification technology related to SiO2 adsorption aerogel, and studies the in-car air odor dissipationcontrol technology. The results show that the concentration of CO in each ventilation mode is higher in thecongested road sections, and the road congestion is the main influencing factor of CO concentration in thevehicle; the PM2.5 concentration in the air of the vehicle is greatly affected by the air quality outside thevehicle, and the road condition and form status have no decisive influence on it; the TVOC concentration inthe car is relatively stable when the window is closed, but in unobstructed road conditions, the TVOCconcentration is lower than that in the congested road conditions and it presents a declining trend; in the airinside the vehicle, for the CO, TVOC and PM2.5 suspended particulate matters, etc., we can use activepurification technology related to SiO2 adsorption aerogel to control and dissipate the odor and air pollutants inthe vehicle effectively.
