Fruit.
Be dissolved VOC waste gas component with before photocatalyst interfacial contact, in advance catalysis generate most easily lured by photocatalyst
The aerosol receptor of catalytic decomposition is led, particularly, spraying and form droplets particles very tiny, catalyst and VOC waste gas reaction
Surface catalysis disproportionation occurs, forms liquid particles object, suspends in air, therefore generates aerosol receptor, specific surface area is got over
Greatly, the content of dissolved oxygen is higher, and the oxygen atom in water is made constantly to be disproportionated into active oxonium ion, and easier and photocatalyst material exists
It is oxidized cartalytic decomposition effect under the action of light, VOC is decomposed into water and carbon dioxide.
The gas-phase space formed by spraying in air is mixed by catalysis state, so that the cartalytic decomposition effect of photocatalyst
It is stably and controllable.It is friendly to be catalyzed reaction interface, not carbon distribution, that is, do not generate other harmful side products after photocatalyst reaction and participate in anti-
It is easy to react between the reactant answered, photocatalyst generates carbon dioxide gas after decomposing VOC oxidation, by carbon band
It walks, and unoxidized VOC particle can be pushed open and not cause to accumulate, interface has certain self-regeneration mechanism, so that catalysis drop
Solution VOC exhaust-gas treatment ability greatly improves.
The VOC gas of feeding are coated with the hollow sphere of catalysis material by surface, to VOC exhaust gas in aqueous environment boundary condition
The lower a series of disproportionated reaction of completion (collide with catalyst interface, and the mistake of liquid particles is converted to by gas particles by VOC exhaust gas
Journey), this is a kind of process being catalyzed in advance to the progress of VOC gas.VOC exhaust gas mixing gas phase water phase and photocatalyst phase after catalysis
Carry out catalysis oxidation is more advantageous to after contact.So that whole reaction efficiency can be increased substantially to 12.5%-76%.
Preferably, the non-woven fabrics arranges that surface area is big, can improve light-catalyzed reaction to greatest extent in V-shape fold
Efficiency.In general, the light source uses ultraviolet light source.As photocatalyst catalysis material is adhered on the non-woven fabrics of carrier, light is touched
Matchmaker's catalysis material obtains huge specific surface area in same space volume, so that VOC exhaust gas and photocatalyst carry out sufficiently
Contact improves the probability of happening of catalysis reaction.The exhaust gas decomposed is discharged into air by air outlet.
Above-mentioned catalyst can be used vanadium system oxidation reduction catalyst in sncr and preferably adopt in an alternative embodiment
With 2.6% molybdenum, 7% titanium, the surface chemistry sedimentary facies and its oxide of the synthesis of 8%-11% nickel.
Preferably, the first seal plate 12, energy are equipped with close to air inlet side in atomizing humidifier on the apparatus body
Enough avoid scavenging solution excessive.
Preferably, the second seal plate 13 is equipped with far from air inlet side in water filter on the apparatus body；It is described to set
It is equipped with first communicated with fluid reservoir close to air inlet side in the second seal plate on standby ontology and crosses liquid mouth 14.In addition, described set
Third seal plate 15 is equipped with close to air outlet side in inducing catalysis disproportionation filter on standby ontology；In third on apparatus body
Seal plate is equipped with second communicated with fluid reservoir close to air inlet side and crosses liquid mouth 16, scavenging solution can be recycled to storage as far as possible
Flow container.
In an alternative embodiment, the biomimetic features filter core includes the filter core carrier 17 of multi-cavity structure, described
Filter core carries intracorporal number of cavities (or cavity volume size) and is incremented by from the top of carrier to middle part in geometric multiple, and by the load
The middle part of body is successively decreased in geometric multiple to the lower part, and spiral packing part 18, each spiral packing part are filled in each cavity
Towards random distribution.Preferably, spiral packing part upper end is big, lower end is small, and screw pitch is between 2mm-20mm.Specifically,
Filter core carrier may include external framework 20 and internal retainer 21, and retainer is equipped with several ventholes 7.
It should be noted that non-equant conveyor screw changes at random, so that reaction medium system is in a kind of adaptive flat
Weighing apparatus state, when local conveyor screw interface since catalysis reaction carries out too fast generation reaction product accumulation, then, water filter exists always
The steam adulterated in absorption exhaust gas, when condensation vapor is after helix packing element the preceding paragraph time, with continuing to build up for water droplet
Molding, reactant accumulation in short-term can change cross section of fluid channel, change flow velocity, accelerate the movement of deposit, avoid blocking, in this way
Operating mode be similar to human lung's structure working principle.Therefore, the biomimetic features filter core in the invention is very sharp
In rinsing, dirt being discharged, the deposition blocking of fine particle is avoided.
Equally, inducing catalysis disproportionation filter can also use above-mentioned biomimetic features, and carrier also uses multi-cavity structure
Filter core carrier, the filter core carries intracorporal number of cavities (or cavity volume size) from the top of carrier to middle part in geometry times
Number is incremented by, and is successively decreased to the lower part in geometric multiple by the middle part of the carrier, is filled in each cavity several described hollow
Sphere corresponds to different directions on hollow ball equipped with several openings.Gas phase after inducing catalysis is disproportionated obtains huge ratio
