The utility model by made of the quartz fibre covered with titanium dioxide VOC degrade filtering layer to VOC exhaust gas into
Row light-catalyzed reaction produces oxidability extremely strong free hydroxy and active oxygen, has the function of very strong photoredox,
It is oxidable to decompose various organic compounds and part inorganic matter, the cell membrane of bacterium can be destroyed and cure the protein of virus, it can
Bacterium and decomposing organic pollutant are killed, organic pollution is resolved into free of contamination water (H2O) and carbon dioxide (CO2), because
And there is extremely strong sterilization, deodorization, mould proof, anti-fouling and self-cleaning, purification gas, maintenance cost is low and does not generate secondary pollution,
And doing that base material translucency is good, surface area is big using quartz fibre, catalytic efficiency increases substantially.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model is a kind of VOC degradation treatments system, the pre- place including passing sequentially through pipeline connection
Manage device 1, VOC degradation treatments device 2 and exhaust fan 3；The VOC decomposition apparatus 2 includes VOC degradation filtering layers 21 and ultraviolet
Lamp 22, VOC degradation filtering layers 21 are made of quartz fibre, and quartz fiber surface is covered with titanium dioxide layer.VOC degradation filtering layers 21
The structure type being made of quartz fibre can be silica wool, quartzy thin slice, quartz fabric or quartz fiber felt etc..
VOC decomposition apparatus 2 includes the cavity volume 23 of supplied gas flowing, and cavity volume 23 is built-in with one or more groups of VOC degradations filters
Layer 21 and ultraviolet lamp 22.In the present embodiment, cavity volume 23 is built-in with multigroup VOC degradation filtering layers 21 and ultraviolet lamp 22.Preferably, it is more
Group VOC degradation filtering layers 21 are connected and are arranged at intervals with ultraviolet lamp 22, degrade so as to fulfill multistage, can increase substantially VOC degradations
Efficiency realizes that VOC degradation efficiencies are higher than 95%.In this configuration, it is provided in the one side of the VOC degradation filtering layers 21 positioned at head and the tail
Ultraviolet lamp 22, and it is both provided with ultraviolet lamp 22 positioned at intermediate 21 both sides of VOC degradation filtering layers.
