Description

Intelligent in-vehicle air purification system based on FCB planting extraction and negative oxygen ion linkage Technical Field The application relates to the technical field of air purification, in particular to an intelligent in-vehicle air purification system based on FCB planting extraction and negative oxygen ion linkage. Background With the promotion of automobile consumption upgrading and driving health requirements, the air purification of a vehicle-mounted closed space becomes one of the core research and development directions in the fields of automobile industry and automobile accessories. The interior of the automobile is a typical small-volume closed space (the effective space in a conventional passenger car is 3-5m & lt3 & gt), and the automobile has the characteristics of multiple pollutant types, easy accumulation and high diffusion speed, and the core pollutants are divided into the following categories: particulate pollutants, including PM2.5 entering from the outside, road dust and pollen, and smoke dust, dander, fabric fibers and the like generated in the vehicle, are easily inhaled into the respiratory tract by a driver, cause discomfort of the respiratory tract and easily adsorb harmful gases to form composite pollutants; Gaseous pollutants, namely volatile harmful gases such as formaldehyde, benzene series, TVOC and the like which are slowly released by automotive interiors (plastics, leather and adhesives), second-hand smoke, food peculiar smell, air conditioner mildew and the like which are generated in the driving process, wherein the pollutants are difficult to thoroughly remove in a physical way, and part of the gaseous pollutants have the characteristics of slow release and long-term accumulation; The microbial pollutants comprise escherichia coli and staphylococcus aureus which are bred at air-conditioning air channels, seats and foot pads, and common microorganisms of respiratory tracts which are brought in when people take the passengers in season change and multiple people take the passengers, and the pollutants are easy to multiply in a vehicle-mounted warm and humid environment (the temperature is 25-35 ℃ and the humidity is 60-80%), so that the risk of cross infection of drivers and passengers exists. At present, the scheme of purifying the air in the vehicle is mostly single, for example, the negative oxygen ions are released in the vehicle at present commonly so as to purify the particle pollutants, but the purifying effect of the negative oxygen ions on the gaseous pollutants, the peculiar smell and the microbial pollutants is not obvious. And then, the FCB is used for planting and extracting, purifying microbial pollutants, destroying the membrane structure of bacteria/viruses, purifying gaseous pollutants and peculiar smell, decomposing formaldehyde, VOC, smoke smell and the like. However, if negative oxygen ions and FCB are used together for extraction, the negative oxygen ions and FCB are in conflict with each other. Specifically, on one hand, because the negative oxygen ions are tiny particles with negative electricity, electrostatic adsorption can be generated between the negative oxygen ions and organic active molecules (such as pinene and plant antibacterial components) extracted by FCB, so that the extracted molecules are agglomerated and cannot be freely diffused into a vehicle. On the other hand, FCB is planted and extracted into organic volatile molecules, trace mist particles can be formed in the air, and the particles can become a neutralizing carrier of negative oxygen ions, namely, the charges of the negative oxygen ions can be quickly neutralized by the planted and extracted mist particles, so that the negative ions are changed from 'active small particle size' to 'no-charge large particle', and electrostatic sedimentation can not be realized on PM2.5 and other particles.
