Description
Technical field
The present invention relates to VOC high-efficient purification spray in a kind of car, belong to air purification field.
Background technology
With the development of national economy, increasing people has automobile, and the time that people spend in car also gets more and more, and vehicle air environmental quality becomes the hot issue of people's growing interest.In in-vehicle air environment, volatile organic matter (VOC) is one of major pollutants affecting air quality in vehicle, and toxicity is high, harm is big, is the principal element causing " syndrome of driving, new car taste ".To the requirement of quality of life with make people require more and more higher to vehicle air environment and comfortableness to healthy concern, in how improving in-car air quality and administering car, VOC pollutes extremely urgent.
Research shows that free VOC concentration is directly proportional to vehicle interior temperature, vehicle humidity or automobile discharge capacity in car, is inversely proportional to car inner volume, car age or total kilometrage, changes with the difference of air-flow, sampling position or vehicle class in draft type, the speed of service, car.In sample investigation discovery car, VOC concentration is less less than the vehicle up to standard of country's Indoor Air Quality standards limit value, all there is pollution in various degree, common contaminant such as formaldehyde, acetaldehyde, methacrylaldehyde, benzene,toluene,xylene, ethylbenzene, styrene, n-butyl acetate, hendecane etc..Due to each side reasons such as existing manufacturing process and car decorations materials, in evading car from source completely, the current possibility of VOC is still less.
In car, VOC pollutant is complicated and changeable, and the administering method more popularized at present can be divided into ventilation, absorption administer and decompose improvement.Ventilation is the method more effectively reducing VOC concentration in car, but for closed environment such as air-conditioned coach etc., then the method is unworkable.Absorption is administered and is then divided into passive adsorption type and active absorbent-type, passive adsorption is administered and is mostly used porous material such as molecular sieve, adobe, activated carbon etc. to be statically placed in car, material is utilized to complete the enrichment to VOC contamination gas compared with Large ratio surface, thus reach to remove the effect of VOC, the method truly has certain adsorption effect to contamination gas, but owing to the true environment interior ornaments VOC that gets off constantly distributes, and adsorption rate is often not as good as pollutant rate of release (High temperature is particularly evident according to lower summer), thus VOC concentration remains high in causing car, clean-up effect is relatively low；The actively mode then mostly using intensified ventilation of absorbent-type, insert vehicle-mounted clarifier as porous material is made purifying filter element, due to the stronger ventilation of clarifier, can greatly improve purification speed, thus VOC concentration in significantly reducing car, owing to needing supporting purification ventilation equipment, input cost is higher.Decomposing and administering general chemical oxidation Decomposition, catalysis oxidation Decomposition and photochemical catalytic oxidation decomposition isotype, chemical oxidative decomposition commonly uses KMnO4、ClO2And peroxide etc. carries out oxidation Decomposition by force to VOC, owing to oxide itself has certain harm to human body, the method need to evade diffusion and the suction of strong oxidizer；Catalysis oxidation Decomposition is then common on the catalytic degradation of the little molecule such as formaldehyde, acetaldehyde, common used material is the modified oxide materials such as Pt, Au, Pd, the supported porous material of Mn base, biology enzyme etc., but then helpless to the aromatic compound such as benzene, toluene under the method room temperature；Photochemical catalytic oxidation is decomposed all has certain degradation property to major part VOC, but higher to light source requirements and poor to degradation effects such as aromatic hydrocarbons, therefore administers arene compounds the method also inadequate.
Air pollution treatment material is varied, liquid sprays class and solid state class can be divided into according to occupation mode at present, solid state class many with absorption based on or absorption combine resolution model realize purify air purpose, in the case of lacking circulation, solid-state administer material result then cannot get highlighting；Spray is then cheap with it, and the spraying actively features such as improvement are by relatively broad concern.Existing market air treating class spray can be roughly divided into three classes: natural extract, biology enzyme, photocatalyst.Wherein natural extract is many covers etc. the lifting that method realizes air quality with fragrance, and cannot really remove harmful pollution gas, biology enzyme rule is to extract the purpose that biological oxidation enzyme reaches oxidation Decomposition contamination gas, but the albumen feature due to enzyme self, having cause allergy equivalent risk, photocatalyst is then the wider class improvement material in current market, but higher to light source requirements, and poor to degradation effects such as aromatic hydrocarbons, therefore administer arene compounds the method also inadequate.
