The specific embodiment
Below in conjunction with the drawings and specific embodiments content of the present utility model is described in further details.
Embodiment:
See also shown in Figure 1, the monolithic case 6 of fan blade type photocatalysis phase transfer device is made by materials such as corrosion-resistant, difficult absorption organic gas, be located at gas-circulating system, photocatalysis phase transfer system and liquid phase photocatalytic degradation system in the shell 6 successively, gas-circulating system comprises the gas access 1 that is located on shell 6 one ends, between gas access 1 and gas-phase photocatalysis reaction zone, dust filter screen 2 is installed, thereby can effectively intercepts the photochemical catalyst inactivation that the invasion of particle such as dust in the air causes.On the dust filter screen 2, be provided with air inlet turbofan 3 on a side of photocatalysis phase transfer system, airborne dusty gas enters main body gas-phase photocatalysis reaction zone after filtration under the power of air inlet turbofan 3.Gas-phase photocatalysis phase transfer main body reaction zone has many first ultraviolet sources 5 according to space mounting, and reaches the thin-film material layer 4 that absorption liquid container inner wall installation load has photochemical catalyst between uviol lamp, and this thin-film material layer 4 can be TiO
2The glass of photocatalyst film, the area that can increase photochemical catalyst thus to be accelerating light-catalysed efficient, is provided with the fan blade 7 of loaded optic catalyst film towards first ultraviolet source 5, and load has photochemical catalyst TiO on the fan blade 7
2Organic pollutant enters main body light-catalyzed reaction district by inlet 1 and enter liquid phase light-catalyzed reaction district by outlet pipe 8 after the photocatalysis hydrophiling, outlet pipe 8 one ends and photocatalysis phase transfer system connectivity, the other end inserts under absorption liquid 11 liquid levels, in like manner, liquid phase photocatalytic degradation zone is made up of the glass 12 and the detachable absorption liquid absorption liquid container 14 of second ultraviolet source 9, saturating ultraviolet light quartz glass 10, absorption liquid 11, loaded optic catalyst film, and the gas behind absorption cleaning enters air by gas vent 13.Air in the environment through the circulation once again the system of entering carry out repeatedly circularly purifying.
See also shown in Figure 2ly,, in photocatalysis phase transfer system, also vertically be provided with and be used to isolate adjacent first the TiO as light source 5 when first ultraviolet source 5 when being a plurality of
2The glass 4 of photocatalyst film.
When power connection, bleed blower fan 3, first ultraviolet light source 5 and second ultraviolet light source 9 and fan blade 7 worked simultaneously, in the gas-phase reaction district and the liquid phase absorption region all form the photocatalytic activity district, air enters the gas-phase reaction active region through air admission hole 1, hydrophobic organic gas molecule and catalyst surface and airborne hydrophily oxidative free radical reaction and then by hydrophiling.Because organic molecule is changed into CO by thorough photocatalytic-oxidation
2And H
2O need experience the step of a lot of complexity, and experience long time, for shortening the required time of degradation of organic substances, the utility model has been introduced fan blade 7, the active sites that under the power that fan blade 7 rotates and the blower fan 3 of bleeding is brought, breaks away from catalyst surface thus through the organic gas molecular energy of hydrophiling fast, loop jump is finished the transfer from the gas phase to the liquid phase to liquid phase rapidly, and other organic gas molecules will occupy the photocatalytic activity position again and be transferred to liquid phase until oxidized hydrophiling.In liquid phase, since photocatalysis, TiO
2There is the very strong electronic capability that gets the valence band electron hole that the surface produces, and can capture the electronics in the organic pollution, produces strong hydroxyl radical free radical OH in water.It is a kind of extremely strong oxidant, so can carry out rapid light degradation to the organic pollution in the water, exhaustive oxidation generates carbon dioxide and water.Tail gas will enter atmosphere by venthole, and unabsorbed organic gas molecule repeatedly purifies the circulation access to plant, until final thoroughly degraded.
Adding material such as alkalescent in absorption liquid makes absorption liquid be alkalescent, be because the organic gas molecule of hydrophiling is faintly acid mostly on the one hand, the alkalescent absorption liquid can absorb the hydrophiling organic gas molecule in the gas more fast and effectively, thus organic content in the air of degrading faster; This weakly alkaline solution can absorb the carbon dioxide that produces in the photocatalytic degradation process on the other hand.When need changing absorption liquid, add new absorption liquid again as long as absorption liquid absorption liquid container 14 disassembled.This photocatalysis phase transfer air cleaning unit can not only be removed airborne organic gas fast, and absorbing carbon dioxide, and non-secondary pollution reach organic purpose in the fast purification air, and be simple to operate, quick.
Above-listed detailed description is at the specifying of the utility model possible embodiments, and this embodiment is not in order to limiting claim of the present utility model, does not allly break away from the equivalence that the utility model does and implements or change, all should be contained in the claim of this case.
