Gas or liquid easily take away titanium dioxide granule, reduce the content of photocatalyst of titanium dioxide, reduce photocatalyst purifier
Working efficiency.
In order to ensure the stability of the long-time service of photocatalyst purifier, the photocatalyst material in clarifier is needed to consolidate
It is fixed.The process of photocatalyst catalytic degradation organic pollution is happened at the surface of photocatalyst material, therefore, in fixed composite photo catalyst
While material, it is made to have sufficiently large surface again.
Invention content
A kind for the treatment of effeciency of the utility model offer is high, stability is good, the convenient photocatalyst catalytic exhaust of maintenance of clean-up is empty
Gas purifier.
The utility model adopts the following technical solution：
A kind of air purifier of photocatalyst catalytic exhaust, including stainless steel babinet, light is coated on stainless steel cabinet wall
Ion reflections layer, the ultraviolet photooxidation fluorescent tubes of transverse and longitudinal uniform array UV in stainless steel babinet, stainless steel babinet four sides inner wall and UV are ultraviolet
Composite photo catalyst material diaphragm is installed, composite photo catalyst material diaphragm is fixed with stent between photooxidation fluorescent tube.Tank ends are distinguished
Equipped with import and outlet.
Photoion reflecting layer is equably paved with each face of babinet.
Porcelain bushing is nested with outside the ultraviolet photooxidation fluorescent tubes of UV.
Import is equipped with outlet and opens quick detachable filter device soon, opens soon in quick detachable filter device using nano-titanium dioxide
And activated carbon is as filtering adsorbing material.
Composite photo catalyst material diaphragm is the latticed diaphragm being compiled by carbon fiber, and main component is that nanoscale corner post is sharp
Titanium-type titanium dioxide.
The utility model provides a kind of air purifier of photocatalyst catalytic exhaust, and tail gas is nanoscale by main component
The composite photo catalyst material diaphragm of corner post anatase titanium dioxide under the ultraviolet photooxidation fluorescent tube irradiations of UV, carries out catalysis reaction,
Under room temperature, when wavelength is when in the wavelength illumination to titanium dioxide granule of below 260.7nm, valence band electronics by light quantum institute
Excitation transits to conduction band and forms free electron, and forms a positively charged hole in valence band, thus forms electron-hole
It is right.Using the oxidation in generated hole and the reducing power of free electron, water, the oxygen of titanium dioxide and surface contact occur
Reaction generates the extremely strong free radical of oxidizing force, these nearly all organic substances of free radical decomposable asymmetric choice net, by the protium contained by it
Become water and carbon dioxide with carbon.Photoion reflecting layer reduces the loss of ultraviolet light, make vent gas treatment process it is more stable,
Treatment effeciency higher extends the service life of clarifier.The utility model makes foul gas carry out deodorization decomposing, purifying efficiency
Up to more than 99.9%.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
