In recent years, with the conductor oxidate is the multiphase photocatalysis oxidizing process of catalyst, with its room temperature deep reaction, non-secondary pollution and can directly utilize light to come activating catalyst, drive superior function such as oxidation reaction, and become a kind of ideal environment pollution control technology, wherein TiO
2Performance best.The semiconductor light-catalyst material is used aspect air cleaning to some extent, as is coated with TiO
2Construction materials such as pottery, sheet material and be coated with TiO
2Airstrainer (device) etc.Along with the development of nanotechnology, nano-photocatalyst material (Nano semiconductor catalysis material or nanometer mixed light catalysis material) has also begun to be applied to air purification field.Yet these nano-photocatalyst materials exist very big selectivity, for example TiO for irradiates light
2The absorption threshold value less than 400nm, its band-gap energy is 3.2eV, is equivalent to the 387.5nm photon energy, and natural light is 300nm as the minimum wavelength of the sunlight that arrives at ground, 300.0 the ultraviolet luminous energy the between～387.5nm only accounts for about 1% of solar energy, and is low to the utilization rate of sunlight.Therefore, these utilize the light-catalyzed reaction efficient of photocatalysis air cleaning device of natural light lower at present, and the effect of air cleaning is restricted.
The patent No. is ZL02235255.4, name is called the utility model patent of " tubular photocatalysis air purification and disinfection apparatus ", its shortcoming is: the purification face that is coated with nano-photocatalyst material is unidimensional, and the utilization rate of nano-photocatalyst material is low, thereby air cleaning efficient is low.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, a kind of photolytic air cleaning ventilation device is provided, it is mobile that this device can rely on self to drive air, and response area is big, the convective mass transfer ability is strong, full contact, have air cleaning and a ventilation function, purification efficiency height simultaneously.
For achieving the above object, the technical solution used in the present invention is that a kind of photolytic air cleaning ventilation device has air intake conduit and air-out conduit on shell, blower fan axle and motor shaft are fixedly connected, fibre bundle is at least two bundles, fixes with the blower fan axle, is coated with nano-photocatalyst material on the optical fiber of formation fibre bundle, uviol lamp is positioned at the blower fan axle, fixes with support, support is fixed on the shell, and the motor-driven motor shaft rotates, and motor shaft drives the blower fan axle and fibre bundle rotates together.
The invention has the advantages that: this device adopts fibre bundle to constitute blade, the nano-photocatalyst material that applies on optical fiber is a photocatalyst, and fibre bundle is shone with uviol lamp, has big, the purification efficiency that the clears the pollution off height of air and photocatalyst contact surface, and simple in structure, reliable operation, do not have advantages such as secondary pollution, especially be fit to be applied to the air cleaning that submarine, hospital etc. have enclosed space.
