Further scheme is: oxonium ion sterilize integrated generator (2) and/or photocatalyst honeycomb drainage screen (1) can also be housed in the cavity (9).
Further scheme is: cavity (9) but in the light direct projection can also be housed to the UV-A Burdick lamp (4) of photocatalyst honeycomb drainage screen (1).
Further scheme is again: photocatalyst honeycomb drainage screen (1) is an aluminum-base nano photocatalyst activity charcoal honeycomb drainage screen (1).
In this utility model:
One, aluminum-base nano photocatalyst activity charcoal honeycomb drainage screen:
Be widely used in to handle and contain organic gas and foul gas and microbial bacterials such as benzene class, phenols, esters, alcohols, aldehydes such as toluene, dimethylbenzene, benzene.
Characteristics:
1. adopt the aluminium base honeycomb substrate of through-hole structure.Compare with other drainage screen, have better aerodynamics performance, bulk density is little, and specific surface area is big, absorption decomposition efficiency height, and air resistance coefficient is little.
2. nano photo-catalytic and the active carbon with high-quality, high absorption property is adsorbing material in the carrier, and its absorption decomposition rate is fast, and saturated extent of adsorption is big.
The action principle of nano photo-catalytic:
It can powerful absorption decompose harmful substances in air.Because nano material has very big surface area, a gram nano-powder can have up to a hundred square metres surface area.At its surface adsorption impurity, make the harmful substances in air lowering of concentration.
It also has light-catalysed characteristics, i.e. decomposing organic matter under illumination condition.Can be used for kill bacteria with viral, also can solve absorption saturation problem harmful substance.Its principle is that nano material has the photosemiconductor effect, behind the light absorbing energy, can produce hole and electron pair.Hole and electron pair are the hydroxyl and the active oxygen of strong oxidizing property with water decomposition, can oxidation Decomposition fall harmful substance.For example: microorganisms such as antibacterial, virus also mainly are made up of protein and enzyme, and the active oxygen that photocatalytic effect produces makes protein and enzyme denaturation and kills or suppress microorganism; Indoor major chemical contaminants is organic chemicals, and hydroxyl, active oxygen that photocatalytic effect produces can be oxidized into organic chemicals harmless inorganic matters such as carbon dioxide, water, help clean air.
The action principle of active carbon:
Active carbon is the most frequently used a kind of material for air purification, is mainly used to the trace toxic gas in the absorbed air.Through the high-efficiency catalytic activity charcoal behind the multiple catalyst soakage, detergent power is common 5-20 times, and its absorption changes chemisorbed into by physical absorption and acts on simultaneously.
Two, Burdick lamp
The principle of Burdick lamp killing microorganisms is: the ultraviolet of generation can penetrate its cell membrane and nucleus, destroys the molecular link of DNA, makes it lose replication capacity or loses activity.Because cell is reproducible not, microorganism soon will be dead, and ultraviolet also can to not having killed microorganism for the first time, kill it in loop subsequently the influence that adds up through its microorganisms of shining.Ultraviolet is the dna molecular key that directly destroys cell, makes it lose fertility, therefore we can say that ultraviolet sterilization is the road that effects a permanent cure.
Ultraviolet absorbability reaches 0.2 micron, and buoyant granule in the air, dust, smog, the bacterium that swims etc. are assembled rapidly, and combining nano photocatalyst technique to high-efficiency decomposes harmful substance in the air, non-secondary pollution.
The UV-C ultraviolet visible lamp main purpose of using in this device is a killing microorganisms, and UV-A Burdick lamp main purpose is that corresponding exciting light catalyst reaches the best use of, makes photocatalyst activity charcoal drainage screen remain the cleaning of work surface.
Three, the oxonium ion integrated generator (ozone, anion) that sterilizes
The sterilizing mechanisms of ozone: ozone has unstable characteristic and very strong oxidability.Because ozone carries an oxygen atom by oxygen molecule and forms, and has determined that it is a kind of temporary form, the oxygen atom that carries is except that oxidation is used up, and the remaining oxygen that is combined as again enters steady statue.
The application of ozone is mainly at artificial sterilization.This mainly is that ozone has very strong oxidability, oxygen atom can oxidizing bacteria cell wall, capture antibacterial life until penetration cell wall unsaturated bond chemical combination intravital with it, its effect is finished at once, and the rapid sterilization effect of ozone is decided by its high reduction potential.
The ozone safe concentration of health ministry regulation is 0.1ppm, and the industrial hygiene standard is 0.15ppm, and labor protection department is defined in that permission work is no more than 10 hours under the safe concentration; U.S. Environmental Protection Agency (EPA) regulation, ozone concentration standard be 8 hourly average concentration must be below 0.08ppm (1ppm ozone=1.963mg/m
3).
The anionic sterilization principle: anion has fresh air, sterilization, medical treatment and health-care effect, is called as " airborne vitamin ".Anion is confirmed to be the effective means that has killing pathogenic bacteria and purify air by medical circle.After its mechanism mainly is anion and antibacterial combines, make antibacterial produce the change of structure or the transfer of energy, impel antibacterial death, reach the purpose of sterilization and sterilization, make that antibacterial successively decreases rapidly in the air.Simultaneously anion very easily with air in small contamination particle adsorb mutually, become charged heavy ion, sink on ground, thereby air be purified.And the negative ion concentration value of optimum human body is 10
6Psc/cm
3Airborne negative ion amount can promote the human body metabolism, purifies the blood, and strengthens cell function, U.S. face calmness, autonomic nerve elimination insomnia anxiety, also diseases such as asthma, bronchitis, allergic rhinitis is all had therapeutical effect.
When ozone concentration is 0.03ppm, negative ion concentration is 10
6Psc/cm
3The time, sterilizing ability has improved 10 times than use is any separately, and sterilizing rate is more than 94%.
