Organic pollutants and the major class of organic pollution two, wherein organic pollution account for the overwhelming majority.
Organic exhaust gas not only have stimulation to human body and various sense organs, and with certain toxicity, some can produce " three
Cause effect ", accumulated in human body, cause canceration and gene mutation, high risks are caused to health.Meanwhile, can also cause
Environmental pollution, forms acid rain, causes photochemical fog, damage the ozone layer, cause climate warming in an atmosphere；Tire out in soil
Product, destroys ecological environment；Polluted underground water, so as to influence health indirectly.Therefore, seek cost-effective governance way and
Control program has hot issue to be solved as countries in the world.
According to physical form final after treatment come point, pollutant abatement technology can be divided into two classes to organic exhaust gas, and a class is
Non-destructive technique is absorption method, can make concentration and separation by changing the physical condition such as temperature, pressure in certain technical process,
It is final to be recycled with former physical form, prevented from source or reduce environmental pollution, it is a green for comprehensive utilization of resources
Green technology, mainly including solution absorption method, active carbon adsorption, UF membrane and common technique etc. condensation method.It is another kind of to be broken
Bad property technology is destruction technology, and the general technology by chemistry or biology makes to be converted into carbon dioxide, water and nontoxic or toxicity
Small inorganic matter, mainly this kind of method of technology belongs to environment including heat damage, light degradation, plasma oxidation, biodegradation etc.
Friendly technology, the carbon dioxide and vapor of generation do not have toxic action to human body.It is generally organic in organic exhaust gas
The concentration of thing is low, and recovery value is limited, and non-destructive treatment technology is because of deficiency in economic performance, it is difficult to large-scale promotion application.And it is hot
Often there is the big defect of high energy consumption, floor space in destruction, plasma oxidation, biodegradation, it is difficult to suitable for low concentration, greatly
The treatment of flow organic exhaust gas.
The content of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of organic gas catalyst oxidative system.
A kind of organic gas catalyst oxidative system, including：Some groups of reactors in parallel；It is characterized in that：The reaction

Between adpting flange, the inwall in photodissociation cabin is provided with sprayed coating, and ultraviolet lamp tube, two adjacent groups uviol lamp are fixed with each photodissociation cabin
Angle between pipe is 90 °, and one end of reactor communicates with air inlet pipe, and the other end of reactor is communicated with escaping pipe, reactor
Between air inlet pipe, switching valve is equipped between reactor and escaping pipe.
Preferably, the material of the catalyst network is titanium or titanium dioxide.
Preferably, the material of the sprayed coating spraying is titanium or titanium dioxide.
Operation principle of the invention is：
TiO2Or the catalyst network of Ti materials, sprayed coating, when being penetrated by UV illumination, the electronics on titanium atom is by ultraviolet light
Excite, produce electronics-hole pair, this electron-hole pair is combined with water and oxygen in air, can produce a kind of with super
The O of strong oxdiative power2-With hydroxyl free radical OH-, can make to decompose generation CO containing the organic matter in organic gas waste gas2And H2O,
And the nontoxic inorganic compound of Partial cleansing degraded generation, so as to reach the mesh of the degraded of organic exhaust gas, deodorization, sterilizing
's.
Compared with prior art, beneficial effects of the present invention：
1）By TiO2Or the catalyst network of Ti materials, sprayed coating realize the treatment of organic exhaust gas, without adding other chemical drugs
Product, have the advantages that operating cost is low, equipment is simple and reliable, clean environment firendly；
2）By setting some groups of reactors in parallel, while switching valve is installed at the two ends of reactor, can be according to exhausted air quantity
Size adjust switching reactor quantity, so as to greatly improve the adaptability of system；Need to safeguard in reactor simultaneously
When, turn off switching valve, you can realize the dismounting and maintenance of reactor, it is greatly convenient for users to use.
