Technical field
The utility model is related to Organic Waste Gas Pollution control technology field, specifically a kind of suitable for photocatalysed purifier The combining structure of UV light sources and catalyst layer.
Background technology
Photocatalysis purifying technology mainly uses photochemical catalyst titanium dioxide (TiO2) absorb the extraneous luminous energy for radiating so as to It is directly translated into chemical energy.When energy is more than TiO2During the light irradiation semiconductor of energy gap, photo-excited electron transits to conduction band, Form conduction band electron (e-), while leaving hole rank (h in valence band+).Due to the discontinuity of semiconductor energy gap, electronics and hole Last a long time, they can under electric field action or diffusion by way of move, with absorption in semiconductor catalyst particle There is redox reaction in the material on surface, or captured by lattice surface defect.Hole and electronics are in catalyst particle Portion or surface also can direct combination, hole can with absorption catalyst particle surface oxygen or H2O has an effect generation hydroxyl Base free radical HO, HO are a kind of very high particles of activity, without the oxidation gas chromatography for selecting and can be allowed to mineralising.
At present the catalyst layer of photocatalysed purifier adopts plate armature, UV light sources and photochemical catalyst to be arranged to independent Module, is placed in inside photocatalysed purifier;Because the air speed of photocatalyst layer is relatively fixed, the corresponding purification of unit cross-sectional area Ability is more fixed, while the catalyst layer and light source of independent arrangement occupy the larger inner space of clarifier, UV photons exist Decaying in motion process also can significantly affect the purification efficiency of clarifier, and the detergent power of single devices is limited to be also unfavorable for only The maximization of change equipment.
Utility model content
The purpose of this utility model is to provide a kind of UV light sources and the group of catalyst layer suitable for photocatalysed purifier Close structure, improve photocatalysed purifier purification efficiency, realize the maximization of cleaning equipment, to solve above-mentioned background technology in carry The problem for going out.
For achieving the above object, the utility model provides following technical scheme:
A kind of UV light sources and the combining structure of catalyst layer suitable for photocatalysed purifier, including clean unit, it is described Clean unit is arranged in photocatalysed purifier, and photocatalysed purifier left end is provided with air inlet, and right-hand member is provided with air outlet;Photocatalysis Clarifier inside left and right two ends are equipped with draw-in groove, and clean unit is fixed in photocatalysed purifier by draw-in groove;The purification is single Unit includes photocatalyst layer, UV light sources and filter, and the photocatalyst layer coats undulate on the glass fibers, UV light sources position In the position of waveform photocatalyst layer trough, each photocatalyst layer left and right sides is equipped with filter.
As further program of the utility model:The air inlet and air outlet position are symmetrical, and aperture is identical.
Compared with prior art, the beneficial effects of the utility model are:The utility model simple structure, reasonable in design, energy Efficiently and stably purify the low concentration VOCs waste gas that each class factory is produced;Can be by the disposal ability of single devices on existing basis On be enhanced about more than once;Detergent power can be lifted 40% using UV light sources and photocatalyst complex structure;Can be by monomer The detergent power of equipment is by 20000 present~25000m3/ h is lifted to 40000~50000m3/ h, realizes cleaning equipment Maximize.Whole cleaning system flexible operation, continuous and discontinuous can run, working stability;It is widely applicable, can be applicable to include stone Various industries such as oiling work, spraying spray painting, printing printing and dyeing.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure:1- air inlets, the equal wind filter elements of 2-, 3- draw-in grooves, 4- photocatalyst layers, 5-UV light sources, 6- filters, 7- goes out Air port.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1, a kind of UV light sources and the combining structure of catalyst layer suitable for photocatalysed purifier, including purification Unit, the clean unit is arranged in photocatalysed purifier, and photocatalysed purifier left end is provided with air inlet 1, and right-hand member is provided with out Air port 7;Photocatalysed purifier inside left and right two ends are equipped with draw-in groove 3, and clean unit is fixed on photocatalysed purifier by draw-in groove 3 It is interior;The clean unit includes photocatalyst layer 4, UV light sources 5 and filter 6, and the photocatalyst layer 4 is coated on the glass fibers Undulate, UV light sources 5 are located at the position of the trough of waveform photocatalyst layer 4, it is achieved thereby that arranging more in less space Many catalyst and UV lamp pipe, improve the matching degree of light source and catalyst, improve purification efficiency, beneficial to realizing that purification sets Standby maximization;Each left and right sides of photocatalyst layer 4 is equipped with filter 6.Organic exhaust gas enter light catalytic purifying from air inlet Device, after equal wind filter layer realizes high efficiency filter and steady air flow, will by the collective effect of photocatalyst layer and UV light sources Organic principle efficient degradation in waste gas is after water and carbon dioxide, to discharge eventually through air outlet.
