Background technology
Automobile is largely used in life, and requirement of the people to riding comfort, in-car air cleaner, own health is got over
Come higher.In-car is a confined space, sluggish in air circulation, gaseous contamination and peculiar smell easily occurs, and can tire out over time
Product.Especially new car, leather, mahogany, engineering plastics and metal, paint that interior trim is selected etc. can produce the volatility to have organic matter,
Such as benzene, formaldehyde, dimethylbenzene, acetone, these organic matters can have a strong impact on the health of driver and in-car passenger, for a long time
Carcinogenic risk can also be increased in this environment.According to the literature, room air monitoring center of China's decoration association adds up right
200 inspections of new car find that nearly ninety percent automobile all has in-car air severe overweight, exceeded 50 times of left sides of most serious
It is right.
The purification of air technique that current medium-to-high grade automobile is commonly used is filtering, absorption, anion and ultraviolet etc., its center
Adsorbed for adsorbent the part of the heart.Because adsorbent cannot regenerate, it is necessary to frequently change, waste time and energy, and be adsorbed with pollution
The adsorbent of thing as solid waste still need further treatment, not only spend processing cost, also result in unnecessary resource,
, also there is secondary pollution risk in the environment in energy waste.Additionally, adsorbent adsorption capacity and replacement cycle can be with using work
Condition changes, and when having little time to change or cannot determine when to change, ventilating system can cause unexpected injury to occupant.
