Description
Technical field
The present invention relates to the exhaust treatment system in environmental protection equipment, specifically a kind of compound exhaust treatment system of photocatalysis.
Background technology
Environmental protection is increasingly paid attention to by country, process at present the technology of waste gas on the market to have and carry out exhaust gas constituents is cracked and oxidation processes by UVC pipe, but it has shortcoming: for the waste gas that temperature is high, life-span and the treatment effect that can make light oxygen catalytic unit can have a great impact (UVC pipe, ideal temperature is within 75 degree Celsius, if it exceeds this temperature, can weaken the cracking ability of emission molecule key, pipe is also easily broken)；Single UVC photodissociation technology, not ideal to complicated component exhaust-gas treatment effect, only with adding powerful way, waste the energy, conflict mutually with energy-saving and cost-reducing.
A kind of waste gas wastewater light degradation device of CN 201296683Y and system thereof, employ fibre-optical substrate, serve certain effect in use, but cost is more expensive；
CN 103623695A is applied to the organic waste gas treatment system of etching solution removal process, and the scope of use is less.
CN 203916427U photocatalysis organic waste gas treatment system, have employed ultraviolet lamp tube and TiO2 coating, the virus killing effect of uviol lamp combines the reaction of TiO2 and serves certain effect, but the UVC of ultraviolet lamp tube manages, ideal temperature is within 75 degree Celsius, if it exceeds this temperature, can weaken the cracking ability of emission molecule key, pipe is also easily broken, and uses and has certain limitation.
Summary of the invention
The present invention in order to there is good regulation effect to multiple waste gas, and in the service life of equipment to be taken into account simultaneously, spy proposes a kind of compound exhaust treatment system of photocatalysis.
The technical scheme is that for this, a kind of compound exhaust treatment system of photocatalysis, including gas sampling cover, gas sampling cover connects spray column, it is characterized in that: connecting after described spray column has light oxygen catalytic unit, reconnecting after light oxygen catalytic unit has blower unit；By the first filter screen filtration between light oxygen catalytic unit and spray column, by the second filter screen filtration between light oxygen catalytic unit and blower unit；Being additionally provided with multiple tracks TiO2 filter screen and UVC pipe and ozonator in light oxygen catalytic unit, wherein multiple tracks TiO2 filter screen and UVC pipe and ozonator interval are arranged.
Further it is improved by: TiO2 filter screen and UVC pipe and ozonator are three roads, wherein first TiO2 filter screen is arranged after the first drainage screen, then is sequentially provided with a UVC pipe and ozonator, TiO2 filter screen, the 2nd UVC pipe and ozonator, TiO2 filter screen, the 3rd UVC pipe and ozonator.
Further it is improved by: a UVC pipe and ozonator use 184.9 nano wavebands；2nd UVC pipe and ozonator use 253.7 nano wavebands, and the 3rd UVC pipe and ozonator use 253.7 nano wavebands.
Beneficial effect:
The present invention combines spraying technique, and waste gas first carries out cooling process, can also remove the dust in a part of waste gas simultaneously, does primary purification and reaches to keep the purpose of the cleaning of UVC pipe；Configure catalyst simultaneously, under the effect of catalyst, be greatly improved the efficiency of photodissociation oxidation；The waste gas of high-temp waste gas or complicated component first carries out lowering the temperature, wash after, enter back into light oxygen catalytic unit and carry out after-treatment, overcome the deficiency using monotechnics.
Foul waste gas utilizes spray column washing, cooling, after being input to this cleaning equipment, first passes through the first drainage screen and removes macromole and granule, both waste gas was carried out primary treatment；Next light oxygen catalytic unit utilization light involves ozone and foul gas carries out collaborative decomposition oxidation reaction, utilize the molecular link of antibacterial in high energy UVC cracking foul gas, destroy the nucleic acid (DNA) of antibacterial, then carry out oxidation reaction by ozone, thoroughly reach deodorize and kill the purpose of antibacterial.
Utilize the oxygen molecule in high energy high ozone light Wave Decomposition air to produce free oxygen, i.e. active oxygen, because the taken positron-electron of free oxygen is uneven so need to be combined with oxygen molecule, and then produce ozone, it is commonly known that Pre-Ozonation on Organic Matter has extremely strong Oxidation.
Under the effect of special wave band light, photocatalyst can produce strong catalytic degradation function: toxic and harmful in air of effectively degrading, can effectively kill various bacteria, and the toxin that can antibacterial or fungus be discharged decomposes and harmless treatment, it is also equipped with the function such as deodorization, anti-soil simultaneously.
From structure space, multistage catalytic oxidation structure not only ensure that catalysis specific surface area, played the function of uniform water conservancy diversion simultaneously, ensure to greatest extent in limited space spatially with being fully contacted of special light wave lamp, increase and improve active particle and the touch opportunity of pollutant and time.
From microcosmic, use 184.9 nano waveband cuttings, chain rupture, cracking emission molecule chain, change waste gas DNA structure；Emission molecule is aoxidized by value 253.7 nano waveband, makes the molecule after destruction or neutron be combined with O3, makes organic or inorganic macromolecule malodorous compound strand, in catalytic oxidation process, is transformed into low molecular compound and is allowed to become CO2, H2O etc..Its deodorization reaches as high as more than 99%, and purification, deodorising effect substantially exceed the emission standard for odor pollutants (GB14554-93) that country promulgates for 1993, " discharge standard of air pollutants " (GB16297-1996)；" Design of Industrial Enterprises sanitary standard " GBZ1-2002.
