The indoor air pollution has become a most common and most widely concerned environment problem. Some air cleaning devices have complex structures or produce secondary pollution at present, while the utility model provides an indoor air purifier having the photocatalysis component, which is formed by photocatalysis reaction components, and has no secondary pollution. The cold catalytic membrane has the enhanced function of air purification, which is suitable for various sizes, and can be used in different spaces and as an affix of other household electrical appliances.
Description
The utility model relates to a kind of high efficiency photocatalysis assembly and high efficiency photocatalysis air cleaning unit, particularly a kind of air cleaning unit that adopts photocatalysis and heterogeneous catalysis coupling.
The human time over half is at least spent indoor.Room air pollution has become environmental problem the most general, that cause extensive concern.Indoor harmful gas mainly is the volatile organic matter that produces of radioactive substance such as the volatile organic matters such as formaldehyde of emitting such as ornament materials, the radon that ceramic tile is emitted and living environment (as methyl mercaptan etc.), volatility inorganic matter (as hydrogen sulfide, ammonia etc.), biological pollutant (as bacterium, mould and germ etc.), and it is obviously unhappy that these gases can make the people produce when a few millionths.Usually, harmful substance contents causes harm potential, continuation far above outdoor to human body in the room air.With regard to present commercial production levels and state of ecological environment, can't avoid the discharging of these organic matters and gas pollutant.
At present, miscellaneous air purifier, air cleaner etc. have appearred on the market.Mainly adopt the coupling of the pure and fresh technology of anion air of charcoal absorption technology and plasma generator generation, and become the main flow in market.The activated carbon filtration film has suction-operated, can't decomposing pollutant, just pollutant is transferred on the filter membrane.This film does not have regeneration function, uses some months just must change, and use cost is very high.Used activated carbon filtration film becomes discarded object, causes secondary pollution again." day photo reversal " the type photocatalyst deodorizing film that uses on the air conditioner must often be exposed to the sun in the sun, uses also inconvenient.Yet it is the new technology for the treatment of indoor air pollution in recent years that photocatalytic method purifies the air of a room.Under suitable condition, photocatalysis can non-selectivity ground with the thorough mineralising of the organic matter in vapour-liquid/solid interface, and non-secondary pollution also can the oxidation inorganic pollution, the kill harmful bacterium, has shown its good prospects for application in treating indoor air pollution.
Patent of invention that China declares aspect photocatalysis air-cleaning and utility model patent are existing multinomial.Chinese invention patent (96197457.5) photocatalytic air disinfection of U.S. Universal Air Technology, Inc. application provides the air cleaning scheme in building, a whole building, but complex structure is difficult to use in little space.Chinese patent 98216682.2 provides a kind of method for designing of ozone enhanced photocatalysis air purifier, ozone plays a part to strengthen photochemical catalytic oxidation, but ozone also is a kind of air pollutants, when ozone concentration in the air surpasses certain limit, human body is produced intense stimulus, produce secondary pollution.
The purpose of this utility model is to provide a kind of photocatalysis air purifying device efficiently, it melts photocatalysis, heterogeneous catalysis, anion, electrostatic precipitator technology in one, airborne organic pollution, inorganic gas pollutant be can efficiently decompose apace, flue dust, killing microorganisms pollutant and stink substance removed.
