Operation principle:
Waste gas enters from air inlet 2, enters in electrocatalysis oxidation device 1 through the air inlet 11 of photoelectrocatalysioxidization oxidization device 1, First pass through filter grid 19 and remove a part of impurity, then by plasma module 12 in ion plasma 1a, plasma module 12 Operation principle be its under the control of plasma electric Ore-controlling Role, be positioned at plasma module electric field generating region produce high-voltage pulse electric , by front and back along Pulsed corona discharge precipitous, that pulsewidth is the narrowest (ns), obtaining non-equilibrium high energy low temperature etc. at normal temperatures Gas ions, i.e. produces a large amount of high energy electron, has hydroxyl radical free radical (OH, HO of extremely strong oxidation susceptibility2, O) and son The extremely strong O of oxidisability3Deng high energy active particle.When organic exhaust gas enters in high-pressure pulse electric, organic molecule in waste gas Inelastic collision is carried out with a large amount of active electrons produced in impulse electric field and the high energy active particle such as hydroxyl radical free radical (OH), Make organic molecule chemical bond rupture, series of complex oxidation, degraded chemical reaction occur, finally makes poisonous and harmful in waste gas have Machine thing is changed into harmless material, makes waste gas be purified.
By the waste gas of plasma module 12, after reducer pipe 15, enter uviol lamp district 1b, ultraviolet in uviol lamp district 1b The photodissociation region of photocatalyst net 16 composition that lamp module 12 and both sides include noble metal catalyst produces photolysis to waste gas;Useless Gas is in this region, electron bombardment to be experienced, the oxidation of hydroxyl radical free radical (OH), below 185nm ultraviolet photodissociation, smelly The processes such as oxygen oxidation, electron bombardment, the oxidation of strong oxidizer-OH, positive oxonium ion oxidation, thus reach to purify the purpose of waste gas. Ultraviolet lamp module 13 uses ultraviolet Non-polarized lamp, owing to ultraviolet Non-polarized lamp uses high frequency excitation technology, below 185nm wavelength Ratio significantly improve, appropriate design can reach 12%, simultaneously because the spatial transmission characteristic of high frequency technique, microwave is inherently There is catalysis, so that photodissociation region has possessed dual catalytic function.Photocatalyst net 16 is made up of titanium dioxide, its tool There are double-level-metal network structure, double-layer catalyst structure not only to ensure that catalysis specific surface area, played uniform water conservancy diversion simultaneously High energy, ensure to greatest extent in limited space spatially with being fully contacted of ultraviolet Non-polarized lamp, increase and improve activity grain Son and the touch opportunity of pollutant and time.
Waste gas after photodissociation enters through gas outlet 14, the import 31 of chemical oxidation tower 3 bottom of photoelectrocatalysioxidization oxidization device 1 Enter in chemical oxidation tower 3.Waste gas sequentially passes through packing layer 34, corrugated sheet 33 in uphill process and removes mist layer 32, with Time spray equipment cycle of operation water spray, remove the impurity in removing exhaust gas further.Wherein, the filler in packing layer 34 is hollow plastics Ball, can increase the contact area of gas-liquid, the effect of intensified response, and big that corrugated sheet 33 can go to carry secretly in removing exhaust gas The drop of grain, except mist layer 32 is also one layer of hollow plastic ball, for removing the water smoke in removing exhaust gas.
Finally, the outlet 35 at gas chemically oxidizing tower 3 top reaching discharge standard after purification enters exhaust chimney 4, And finally discharge from the top of exhaust chimney 4.
