Son excites gaseous oxidizer to produce oh free radical；
(4) there is oxidation reaction in organic exhaust gas and oh free radical in oxidation reaction tower；
(5) clean gas pass through to arrange outside blower fan.
Preferably, uv light pipe transmitting high energy ultraviolet in above-mentioned steps (3) oxidation reaction tower, produces and has energy in a large number
Photon, the molecular link that these photon one side can destroy organic exhaust gas combines energy, and oxidant on the other hand can be excited to produce
There is the oh free radical of high energy oxidisability.
Know-why of the present utility model is: oxidant storage tank storing liquid oxidant, and liquid oxidizer is sprayed by atomization
It is changed into gaseous oxidizer after head atomization, uv light pipe launches high energy ultraviolet, produce the photon in a large number with energy, now,
There is the ultraviolet that gaseous oxidizer launches to the oxidation of organic exhaust gas, uv light pipe to organic waste in oxidation reaction tower simultaneously
The splitting action of gas, the strong oxidation to organic exhaust gas for the oh free radical, by three kinds of combined degradation effects to organic exhaust gas
Under, organic exhaust gas are degraded to h2O and co2Small organic molecule, by gas-liquid contact oxidation transformation be gas gas catalytic oxidation, greatly
Shorten greatly oxidization time, organic waste-gas purification efficiency high.
The beneficial effects of the utility model are: one, non-secondary pollution: liquid oxidizer is changed into gaseous oxidizer, keeps away
The a large amount of waste water producing when having exempted from using liquid oxidizer；2nd, organic waste-gas purification efficiency high: uv light pipe, gaseous oxidizer, oh
The organic exhaust gas degradation of three kinds of effects of free radical, the gas gas catalytic oxidation time shortens thousands of times than gas-liquid contact oxidation,
Purification efficiency greatly improves；3rd, invest economic operating cost: under identical purification efficiency, invest and economic operating cost.
