The indoor air purifier is simple in structure, low in cost and convenient to operate, and has a remarkable effect on organic pollutants in air; a used visible-light-induced photocatalyst is relatively high in photocatalytic activity, and the risk of ultraviolet light leakage is inexistent; according to the further technical scheme, adsorption, photocatalysis and filtering technologies are integrated and a high-efficiency purification function is provided.

Description

Indoor air cleaner
Technical field
The utility model relates to air purifying process field, particularly a kind of air purifier.
Background technology
At present processing air-polluting major way is absorption, filtration, electrostatic precipitation etc., and these methods all can not be by contaminant degradation, so the utilization of photocatalysis technology in air cleaning has great significance.
Photocatalysis air-cleaning technology is a kind of technology of utilizing novel composite Nano high-tech functional material, it is low temperature deep reaction technology, photochemical catalyst nano particle is excited to generate electron-hole pair under the light of certain wavelength irradiates, the water generates hydroxyl free radical of hole decomposition catalyst adsorption, electronics makes its hydrogen reduction around become active ion-oxygen, thereby possesses extremely strong oxidation-reduction, the various pollutants of degraded photocatalyst surface and kill bacteria virus.
But photocatalysis air-cleaning technology, aspect practical application, exists catalysis material expensive, and the not high problem of visible light activity.The existence of these problems, has limited photocatalysis technology and has been used widely in air cleaning.
Existing air purifier function is single, is difficult to purify air comprehensively; And existing conventional photocatalysis technology air cleaning adopts ultraviolet light exciting light catalysis material, the risk that exists ultraviolet light to leak.
Utility model content
In view of this, the utility model provides a kind of indoor air cleaner, and the photocatalysis apparatus that adopts LED lamp to activate carries out air cleaning, the risk that does not exist ultraviolet light to leak.
The utility model solves the problems of the technologies described above by following technological means:
Indoor air cleaner of the present utility model, comprise housing, on described housing, be provided with air inlet and air outlet, described air inlet is communicated with the air inlet of photocatalysis apparatus by blower fan, the gas outlet of described photocatalysis apparatus is communicated with the air outlet on housing, and described photocatalysis apparatus is cyanurotriamide modified TiO 2, in housing, the position corresponding with photocatalysis apparatus is provided with the LED lamp that irradiates photocatalysis apparatus.
Further, described photocatalysis apparatus comprises transparent shell, cyanurotriamide modified TiO 2in photocatalysis apparatus, be filled with Supported Melamine modification TiO 2carbon fiber.
Further, described air inlet is provided with NACF net.
Further, described air outlet is provided with HEPA filter.
Further, described blower fan is centrifugal blower.
The beneficial effects of the utility model: indoor air cleaner of the present utility model, simple in structure, with low cost, easy to operate, for airborne organic pollution successful, the photocatalysis apparatus that adopts LED lamp to activate carries out air cleaning, the risk that does not exist ultraviolet light to leak; The visible light catalyst using in this device all has a higher photocatalytic activity by verified in the experiment at degrade liquid phase (methylene blue) and gas phase (toluene) pollutant.In further technical scheme, integrated adsorption technology, photocatalysis technology, filtering technique, provides efficient purification function.
