Description
Technical field
The utility model is a kind of Pollution Control equipment, is specifically related to be used for handling the photo catalysis reactor of air volatile contaminant.
Background technology
Removing VOC (VOCs) at present from air generally is to adopt methods such as absorption, absorption, high temperature incineration and catalytic burning.These methods all have certain limitation, all can bring secondary pollution.Photocatalysis technology have can carry out at normal temperatures and pressures, energy consume low, to characteristics such as the degradation efficiency height of pollutant, the multiple pollutants of can degrading simultaneously, therefore this technology will be a kind of very promising environmental improvement means, be particularly suitable for handling VOC and foul gas in the air.
Volatile contaminant in the photoactivation technical finesse air need be equipped with the photo catalysis reactor of photochemical catalyst.Problems such as present existing photo catalysis reactor structure is different, and some patented technology schemes or like product adopt active carbon cloth, corrugated paper, aluminium sheet etc. to make the photochemical catalyst of catalyst carrier, exist light transmission poor, and sensitive surface is little, and purification efficiency is low.Loaded optic catalyst can keep the adsorption capacity of photochemical catalyst to reactant on glass fibre, effectively reduces the absorption of carrier to light, thereby greatly improves the photocatalysis effect.
The utility model content
The purpose of this utility model is to provide a kind of highly effective photocatalytic reactor of handling volatile contaminant in the air, the titanium dioxide optical catalyst that this reactor adopts glass fiber loaded reactive metal to mix.
Structure of the present utility model is: an end of an elongate housing is that air inlet, the other end are the gas outlet, housing longitudinal axis position is provided with a ultraviolet lamp tube, this ultraviolet lamp tube is fixed by the horizontal porous plate that is located in the housing, the titanium dioxide optical catalyst that the glass fiber loaded reactive metal of filling mixes between housing and ultraviolet lamp tube, the gas outlet end or the air inlet end of housing are provided with blower fan.Said blower fan preferably is located at the gas outlet end of housing.Porous plate in the housing is preferably two, is located at the housing two ends respectively.Inner walls preferably is provided with reflector layer, and reflector layer can be to be close to aluminium foil or the tinfoil paper that inner walls is lined with.Housing can be made by materials such as lucite, plastics, stainless steels.Distance between fluorescent tube and the inner walls can be 0.5-10 centimetre, and is comparatively suitable with 2-5 centimetre when adopting 20 watts uviol lamp.Increase the intensity of illumination of uviol lamp, then can suitably increase filling thickness.Packed density is with 0.1-0.5g/cm
3Be advisable.
The utility model reactor is mainly used in photocatalysis and eliminates sealing and semiclosed human living space (as room, toilet, meeting room, ward and public place of entertainment etc.), and VOC in workshop and the plant and foul gas.Reactor both can use separately, also can use by a plurality of serial or parallel connections.
The beneficial effects of the utility model: simple in structure, can react continuously, the photocatalytic activity height, and have stronger anti-deactivation.
