Description
Technical field
The present invention relates to the environmental protection field, particularly a kind of air purification method and device thereof.
Background technology
As everyone knows, people are long in the outdoor time of staying at indoor ratio, because room air pollution is outdoor 5～10 times, therefore, IAQ (indoor air quality) is bigger than outdoor air to health effects.
Nearly 500 kinds of indoor air pollutants mainly include harmful gas, organic bacterial, pellet, radioactive substance, microorganism, airborne irritated thing etc., and a large amount of novel finishing materials more become main air pollution sources in the modern room.In addition, the room air pollution source also has medicated cigarette, oil smoke, detergent, cosmetics, disinfectant, agrochemical.Use air-conditioning summer, heating installation is used in city, the north winter, people are placed oneself in the midst of in the environment of sealing or relative closure for a long time, air circulation is relatively poor, pollutant will gather indoor, cause severe contamination, that people can feel is uncomfortable in chest, dizzy, nauseating, weak, nasal obstruction, sneeze, tinnitus etc., can cause building syndrome, building associated diseases and chemical substance anaphylaxis, air conditioning disease etc.Based on this, the serious consequence that the room air pollution problem causes has caused people's very big concern, can make the suitable air purifying process of surviving, be more suitable for healthy " artificial environment " and arise at the historic moment.Air purifier is an important class wherein.According to the different principle and the different modes that air are carried out purified treatment, air purifier can be divided into two classes: a kind of is cleaning type, as electrostatic air cleaner and electrostatic air cleaner; A kind of is dedusting degasification formula, as physical absorption formula air purifier, chemisorbed formula air purifier and ionic formula air purifier etc.Except the machine that purifies air specially, have the other products of air purification function in addition: the air-conditioning that can purify air, oxygen bar's skin protection makeup mirror, oxygen bar's eye-protecting lamp etc.
Air purifier structurally more adopts the adsorption filtration mode to carry out air cleaning, function singleness.Its filter material that adopts comprises activated carbon, gel cotton and HEPA (high density filter material) etc., and activated carbon can adsorb and decompose airborne harmful gas, abnormal flavour; The gel cotton can carry out thick layer and purify, absorption larger particles dust; And the clean-up effect of HEPA is better, and it reaches 99.9% to the adsorption efficiency of the above pollutant of 0.3um, thereby effectively purifies the air of a room.In addition, air purifier wants to reach and purifies purpose fully, also sterilization technology efficiently to be arranged, all have for Gram-positive and negative bacterium, staphylococcus aureus, escherichia coli, Candida albicans etc. as AV-990 sterilization finishing technique and to suppress and killing action, can also avoid the filtering blank that causes by antibacterial, mycete, algae etc. mouldy, rotten and produce secondary pollution such as abnormal flavour simultaneously.
Now, air purifier has the function that discharges anion, physiological function to human body truly has facilitation, but airborne anion very easily combines with airborne dust, become and have certain polar contaminant particles, i.e. " heavy ion ", and the heavy ion that suspends still is attracted on indoor furniture, the television screen in the landing process.
Summary of the invention
Technical problem to be solved by this invention is: a kind of air purification method is provided, it is with the collaborative one of ultraviolet light, ozone, microwave, photocatalytic degradation and filtration, and killing pathogenic bacteria is eliminated toxic organics, and remove unnecessary ozone by ozone, reach the purpose of fast purification air.Be the glistening light of waves air purifier of realizing that described method prepares, novel structure, practical.
The technical solution adopted for the present invention to solve the technical problems is such: the air purification method that provides, it is a kind of collaborative integrated filter sterilization degraded of ultraviolet light, ozone, microwave, photocatalytic degradation and adsorption filtration toxic organics effect that utilizes, clean air, its step is as follows, comprising:
A. utilize the microwave of microwave generator that the thalline in the air pollution of coming in is sterilized,
B. utilize the luminous body in microwave-excitation electrodeless ultraviolet light source to send short wavelength's ultraviolet light, action of ultraviolet light produces ozone in oxygen carrier, and ozone and ultraviolet light sterilize to the thalline in the air pollution of coming in,
C. utilize the synergism detoxification of microwave and ultraviolet light, promptly the toxic organics in the air pollution of coming in carried out microwave degradation and photocatalysis oxidation reaction,
D. with the particulate inorganic thing in the inlet air filtration net interception air pollution,
E. decomposing redundant ozone with active carbon is oxygen,
F. discharge the air that purifies.
For realizing the prepared glistening light of waves air purifier of said method, its structure is: be made up of microwave generator and detoxification device, the two is connected as a single entity.The detoxification device is provided with the interlayer that several are formed by active carbon in its housing, they are between air pollution air inlet and clean air outlet, and air inlet is provided with the inlet air filtration net, and the luminous body in electrodeless ultraviolet light source is housed between the interlayer; Fan is equipped with at the air inlet place, and its effect is to blast air, ventilates.
The present invention is different from method and the device thereof that has air cleaning now owing to having adopted, thereby following advantage is arranged:
One. studies show that: environmental protection field " photochemical catalytic oxidation " new technology utilization is by a kind of high-tech advanced composite material (ACM) of the irradiation under ultraviolet ray of specific wavelength, can inspire " electronics-hole " to (a kind of high energy particle), airborne hazardous contaminant is directly resolved into nonpoisonous and tasteless material, thereby reached elimination air-polluting purpose.
They are two years old. and ultraviolet sterilization is by the irradiation of ultraviolet to microorganism, with the organizational structure (DNA-nucleic acid) of change and destroy microorganisms, cause the accounting structure sudden change, the organism forfeiture is duplicated, fertility, function wrecks, thereby reaches sterilization, germ-resistant purpose.
They are three years old. and microwave disinfection utilizes microwave field that the temperature of organism is raise, and protein denaturation influences its dissolubility, viscosity, dilatancy, stability, thereby biology is lost activity.In addition, microwave action can change the biological arrangement polymerization state and the characteristics of motion thereof, and the induced ion flow of microwave field, can influence near the CHARGE DISTRIBUTION of cell membrane, cause the barrier action of film to sustain damage, disturb or destroy the eubolism function of cell, cause bacterial growth to suppress, stop or death.
They are four years old. in this depurator, has interlayer between its air pollution air inlet and the clean air outlet, interlayer is activated carbon supported catalyst, the electrodeless ultra-violet light-emitting body that can send short UV light is housed between the interlayer, because short UV light easily produces ozone, ozone oxidation power is extremely strong, is only second to fluorine, energy is the oxidation Decomposition harmful substance rapidly, thereby plays germ-resistant effect.Sterilizing ability is 600-3000 a times of chlorine.
They are five years old. and air inlet is tackled the particulate inorganic thing with the inlet air filtration net, simultaneously, and the quick ozone decomposition of catalyst that interlayer supports with active carbon behind this depurator, making gives vent to anger does not contain ozone, and with fresh air harmless.
They are six years old. practical: the efficient that purifies air height, can raise the efficiency approximately 50%, light source prolongs about 100 times service life simultaneously.Can be widely used in public places such as family, hospital and office, meeting room, also can be installed in the central air-conditioning air inlet, improve air quality.
