The specific embodiment

This routine wind cabinet cabinet cross section is rectangle, and an end is provided with the return air inlet 2 of band filter screen 3, and the other end is provided with air outlet 7, and ultraviolet sterilization apparatus 5 is installed in the side of heat exchanger towards blower fan 6.

Ultraviolet sterilization apparatus 5 structures are: unit framework 11 is the cuboid frame structure, be installed on the support body 10 in the same way side by side along the face vertical with gas channel, two quartz burners 12 are installed in each unit framework, quartz burner spaces out along the direction vertical with gas channel and is arranged in parallel, the ballast 14 that is electrically connected with quartz burner is contained in 15 li of the terminal boxes of unit framework end, the power line of each unit framework quartz burner all enters in the bus duct box 16 of support body 10, be electrically connected with external power supply, can make the sterilizing unit wiring neat so on the one hand, be convenient to maintenance, and can prevent that ultraviolet ray from shining on the lead, make the plastic insulating layer premature aging of lead.

The utility model also can be equipped with electrostatic precipitation net 17 on the unit framework of the front side of the quartz burner of gas channel and/or rear side the carrier of photocatalyst net 13 that can see through air-flow being set on the unit framework 11 of quartz burner and the online wind of carrier of photocatalyst position.Thereby utilize ultraviolet ray that the irradiation of carrier of photocatalyst net is carried out light catalytic purifying to air-flow, described carrier of photocatalyst net can be a net made of paper, stainless (steel) wire, activated carbon net, foamed ceramics net etc.Electrostatic precipitation net 17 can carry out dedusting earlier to the air-flow that flows through quartz burner and carrier of photocatalyst net, and it is online and reduce the viricidal efficient of sterilization to prevent that grit in the air-flow is attached to quartz burner and carrier of photocatalyst.

This routine carrier of photocatalyst net 13 is foamed ceramic panels of the solid reticulate structure of the immobilized TiO2 of having nano-photocatalyst, foamed ceramic panel is vertical with airflow direction, Fig. 3 is the mounting structure schematic diagram of this routine foamed ceramic panel and electrostatic precipitation net: drawing back the foamed ceramic panel that certain distance is equipped with the solid reticulate structure of the three immobilized TiO2 of having nano-photocatalysts on the unit framework support body of the quartz burner front side of gas channel direction, foamed ceramic panel is vertical with airflow direction, in carrier of photocatalyst net installed in front electrostatic precipitation net 17 is arranged.

Air enters cabinet through filter screen under fan action, carry out heat exchange with heat exchanger, when flowing through ultraviolet sterilization device, the ultraviolet pathogenic microbe killing of being sent by ultraviolet lamp (comprises bacterium, germ, fungi etc.), ultraviolet ray simultaneously shines nano TiO 2 photocatalyst surface immobilized on the solid reticulate structural foam ceramic wafer, but exciting light catalytic nanoparticles, generation has the free radical activity material of extremely strong oxidability, wide spectrum kill virus germ also can be with airborne peculiar smell and organic pollution oxidation, resolve into carbon dioxide, the material that water etc. are nonpoisonous and tasteless, this sample example to air except carrying out ultraviolet sterilization kills the virus, also can carry out nanometer photocatalytic purification, greatly improved the viricidal efficient of sterilization, and this example adopts the foamed ceramic panel of solid reticulate structure to make the carrier of nano-photocatalyst, it is big that this foamed ceramic panel has porosity, the aperture is big, windage is little, the characteristics that specific area is big, make ultraviolet ray be easy to shine immobilized photocatalyst surface thereon, and can prolong the length of carrier gas stream passage and the time of contact of air and nano-photocatalyst greatly, strengthen light catalytic purifying efficient, and foamed ceramics rough surface, the photocatalytic nanometer particle is strong adhesion thereon, thereby can prolong the service life of photochemical catalyst, and it is immobilized on the foamed ceramics of solid reticulate structure that photochemical catalyst can be stablized at a lower temperature, improved activity of such catalysts.

This routine unit framework 11 is of a size of 1000mm * 160mm * 125mm, each frame is parallel up and down to be equipped with two both-end 36W ultraviolet sterilization fluorescent tubes, the ballast 14 of fluorescent tube is contained in unit framework one end, wherein one is the ultraviolet germicidal lamp that can produce drop ozone, thereby can further strengthen the viricidal effect of sterilization, ozone also has cooperative photocatalysis except that itself having the sterilization effect of killing the virus, the effect of fortifying catalytic efficient, its generation can carry out Linear Control by the power of fluorescent tube.Every foamed ceramic panel 13 is of a size of: 155mm * 122mm * 15mm, three foamed ceramics plate levels are fixed on the unit framework support body to drawing back certain distance.
