Adopt blower fan to force unidirectional air-supply, this blower fan is arranged on the arbitrary position in the air channel.
The present invention utilizes anion and water generation hydration anion, hydration anion can generate the hydroxyl that has oxidisability under ultraviolet light irradiation and/or catalyst action, utilize the hydroxyl that generates fast and effeciently to kill airborne antibacterial, virus, thereby reach the requirement of the relevant biological antiseptic of China.
Description of drawings
Fig. 1 is the flow chart of steps of the method for the invention;
Fig. 2 is the structural representation of device of the present invention;
Fig. 3 is the plan structure sketch map of taper diverter of the present invention.
Now the invention will be further described in conjunction with the accompanying drawings and embodiments:
The specific embodiment
As shown in Figure 1, non-filter-type air disinfection method of the present invention is comprised of following steps:
A, add anion and mix homogeneously in treating sterilizing and air, wherein, airborne negative ion concentration is no less than 50/cm after mixing
3Air, airborne water content is no less than and is equivalent to the 2.0 gram/Kg dry air depressed at a standard atmosphere after mixing;
B, through ultraviolet light irradiation and/or catalyst treatment.
Because anion mainly is with negative oxygen ion O in air
2 -Form exists, when having enough moisture in the air, and negative oxygen ion O
2 -Will with water in conjunction with generating hydration anion [O
2 -(H
2O)
n].And airborne hydration anion excites lower meeting fast reaction to generate hydroxyl OH at ultraviolet light irradiation, because hydroxyl is the oxidant that has oxidisability, therefore can kill fast airborne bacterial virus; If the Haber-Weiss reaction under catalyst action, can occur and generate fast hydroxyl OH in the hydration anion, by hydroxyl killing bacteria virus.Two kinds of processing modes of ultraviolet light irradiation and catalyst are carried out simultaneously, and effect is better.
For catalyst, can select iron ion catalyst or copper ion catalyst.
For adopting ultraviolet light irradiation to process, the UV radiation intensity of the marginal zone on this ultraviolet source plane preferably is not less than 25 μ w/cm
2
Method of the present invention can be implemented in the space of relative closure, also can be performed in the air channel of forcing unidirectional air-supply.
For the place of air-conditioned room and relatively dry, need in the A step, increase the artificial steam of making and add in the air; And for the place that air sterilizing is had relatively high expectations, treat that the relative humidity of sterilizing and air is preferably between 45～65%.
Such as Fig. 2, shown in Figure 3, non-filter-type air sterilization device of the present invention, an air channel 1 that has air inlet 11 and air outlet 12 and force unidirectional air-supply is arranged, this air channel adopts blower fan 5 to force unidirectional air-supply, blower fan 5 is arranged on the arbitrary position in the air channel 1, and present embodiment is arranged on the air outlet place in air channel.
In above-mentioned air channel 1, follow distinguished and admirable to being provided with successively anion and steam mixed zone, and ultraviolet light irradiation treatment region.
In anion and steam mixed zone, set gradually anion generator 2 and humidifier 3, the humidifier of present embodiment is the network of rivers (also can be nebulizer).For the anion that anion generator is produced can be dispersed in the air as much as possible, the anion generator of present embodiment adopts the taper diverter to come anion releasing, release aperture 21 on the taper diverter is distributed on the conical outer wall face, thereby anion can be discharged in the incision air channel at a certain angle; Simultaneously, in the air channel between anion generator 2 and humidifier 3 fish scale-shaped diverter 6 is set, wind can only could be come in contact with humidifier 3 by minute ebb interval in the fish scale-shaped diverter round, and in minute ebb interval, anion further is evenly dispersed in the air.
In the ultraviolet light irradiation treatment region, be provided with ultra-violet lamp 4, the UV radiation intensity in the horizontal edge district of this ultra-violet lamp is not less than 25 μ w/cm
2
During the work of this device, blower fan rotates, make formation negative pressure in the air channel and make air enter formation wind from air inlet, when wind enters anion and steam mixed zone, the anion that anion generator discharges is sneaked in the wind and obtain more uniform mixing in the fish scale-shaped diverter, evenly be mixed with the distinguished and admirable when humidifier of anion, humidifier increases the water content in the wind, and water is combined with anion and is generated in a large number the hydration anion; When the wind that contains a large amount of hydration anion enters the ultraviolet light irradiation treatment region, excite lower at ultraviolet light irradiation, the hydration anion can fast reaction generate hydroxyl, the hydroxyl that generates is killed airborne antibacterial and virus immediately, so, be exactly to have met the air of sterilizing from air outlet air out.
Certainly, above-mentioned ultraviolet light is attached can be replaced or associated treatment contains the air of hydration anion with the catalyst treatment district according to treatment region.Namely, by with catalyst by be attached to online or expanded material on, or naturally be deposited in the catalyst treatment district with special shape, when the wind that contains a large amount of hydration anion passes through this zone, under the catalytic action of catalyst, the Haber-Weiss reaction occurs and generates fast hydroxyl in the hydration anion, can immediately airborne antibacterial and virus be killed equally, reaches the ideal effect of sterilization.
