Part is radiated on the photocatalysis push type blade 8 of rotation after passing through light transmission orifice plate 6, is further catalyzed to air；It is generated after reaction
Carbon dioxide and water with air-flow enter liquid reserve tank 10；Alkaline solution inside carbon dioxide and liquid reserve tank 10 chemically reacts
Directly it is absorbed；The vapor that air-flow is carried out of liquid reserve tank 10 is absorbed by desiccant particle 13；Dried and
The gas of low carbon dioxide content；The structure can fully absorb the formaldehyde after decomposition, reduce the humidity for guaranteeing use environment,
Reduce the content of indoor carbon dioxide；The photocatalytic plate of stepped arrangement increases the area with light contacts, improves formaldehyde
Decomposition efficiency.
As a kind of preferred embodiment of the invention, the light transmission orifice plate 6 is glass orifice plate.
As a kind of preferred embodiment of the invention, light transmission deflector 3 is provided on the side wall on the photocatalytic plate 2；Institute
Stating light transmission deflector 3 is in extend obliquely；The end of the light transmission deflector 3 is towards adjacent 2 side of photocatalytic plate
On surface；Light transmission deflector 3 is transparent material, and light transmission deflector 3 beats air-flow directly on 2 surface of photocatalytic plate, and raising is urged
Change effect.
In using the present invention, the bottom of liquid reserve tank is provided with drain shut-off valve；Feed liquor is provided at the top of liquid reserve tank to cut
Only valve；The akaline liquid being added inside liquid reserve tank selects sodium hydroxide, will not generate precipitating, be easy to the cleaning of liquid reserve tank；Pass through
It opens feed liquor shut-off valve and fills alkaline solution；Drain shut-off valve is opened, and liquid reserve tank internal liquid is discharged；Since photocatalytic plate is in rank
Scalariform arrangement improves photocatalysis effect so can come into full contact with light；Photocatalysis push type blade is under the drive of air-flow
Rotation, and contacted with air, further decomposing formaldehyde；The light that ultraviolet emission device issues can be directed through loophole
It is radiated at after plate on photocatalysis push type blade；Desiccant particle and the prior art are without essential distinction；It is replaced in desiccant particle
When, it is only necessary to unclamp the second outer tooth part below desiccant particle placed cavity, dry particle is due to can be from dry under the action of gravity
Drying prescription particle placed cavity is automatically drained out at the second threaded hole；When needing that dry particle is added, the second outer tooth part is locked, and is unclamped
Desiccant particle is added in first outer tooth part from the first threaded hole；After exhaust fan starting, air-flow is successively by passing through mesh plate, light
Gap, light transmission orifice plate, photocatalysis push type blade, discharge pipe, liquid reserve tank, outlet air cylinder and desiccant particle between catalytic plate
After to be discharged to chimney fan external；A part of direct irradiation of light that ultraviolet emission device issues makes formaldehyde on photocatalytic plate
Resolve into water and carbon dioxide；And the effect of light transmission orifice plate can make gas even into lower section；Ultraviolet emission device issues
Another part of light pass through light transmission orifice plate after be radiated on the photocatalysis push type blade of rotation, air is further catalyzed；
The carbon dioxide and water generated after reaction enters liquid reserve tank with air-flow；Alkaline solution inside carbon dioxide and liquid reserve tank
Reaction is learned directly to be absorbed；The vapor that air-flow is carried out of liquid reserve tank is absorbed by desiccant particle；Dried and
And the gas of low carbon dioxide content；The structure can fully absorb the formaldehyde after decomposition, reduce and guarantee the wet of use environment
Degree, reduces the content of indoor carbon dioxide；The photocatalytic plate of stepped arrangement increases the area with light contacts, improves first
Aldehyde decomposition efficiency.
