Description of the drawings
Fig. 1 is method flow diagram according to an embodiment of the invention.
Specific implementation mode
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in attached drawing
The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.It is to be able to be best understood from the disclosure on the contrary, providing these embodiments, and can be by this public affairs
The range opened completely is communicated to those skilled in the art.
Fig. 1 is method flow diagram according to an embodiment of the invention.The waste gas processing method of the present invention includes the following steps：
Step 101：Exhaust gas is passed through emission-control equipment；Make exhaust gas that pre-reaction and main reaction occur in emission-control equipment, obtains
Treated gas；Step 106：By treated, gas exports emission-control equipment.Wherein, pre-reaction includes the following steps：
Step 102：Centrifugation demisting is carried out to exhaust gas；And step 103：Optical plasma reaction is carried out to the exhaust gas after centrifugation demisting；
Wherein, main reaction includes：Step 104：Oxidative absorption liquid is uniformly sprayed on filler using spray oxidation furnaces；And step
105：Make to pass through filler by the exhaust gas of pre-reaction.
In said program, the reaction principle of pre-reaction：Optical plasma equipment passes through high energy UV lamp pipe and photocatalyst composition, hair
The wavelengths of ultraviolet radiation gone out is 160nm~185nm, and corresponding photon energy is respectively 800KJ/mol and 647KJ/mol.And such as
To crack the molecular link of organic exhaust gas molecule, the photon energy emitted must can be more than the combination of organic exhaust gas molecular link
It is high.Pending organic exhaust gas includes mainly hydrogen sulfide, ammonia, methyl sulfide and methyl mercaptan etc..Table 1 lists rubbish foul waste gas
The combination energy corresponding to main molecules key and the molecule that middle pollutant includes.Point of major pollutants as can be seen from Table 1
Son is low in conjunction with photon energy that can be than 160nm and 185nm wavelength high energy ultraviolet rays, therefore under high-energy ray irradiation, rubbish
Molecular cleavage in rubbish foul waste gas is converted into atom and radical ion in ionic condition.Therefore it is set when organic exhaust gas enters
It postpones, cracking reaction can be completed wherein.
Molecular link in 1 foul gas of table and corresponding bond energy
| In conjunction with | Bond energy (KJ/mol) | In conjunction with | Bond energy (KJ/mol) |
| H-N | 389 | C-H | 413.6 |
| H-C | 347.9 | H-S | 339 |
| C-C | 607.0 | C-N | 291.2 |
| C-O | 326.0 | C-N | 305.0 |
| O-O | 146.0 | S-S | 268.0 |
On the other hand, inside the optical plasma equipment under the direct irradiation of ultraviolet rays, the oxygen molecule in fresh air
It is cracked to form ozone, chemical process is as follows：
UV(160nm-185nm)+O2→O+O+(active oxygen)；O*+O2→O3(ozone)；
The property that is generated active ozone by be cracked into the atom and radical ion in ionic condition
Foul waste gas carries out Strong oxdiative reaction, these organic gas through ultraviolet rays irradiation cracking are reassembled into harmless or low evil
Compound, such as water, carbon dioxide etc. is generated without waste and sewage in the oxidation process, therefore will not generate two to environment
Secondary pollution.The cracking of material molecule key, oxidation process in several organic exhaust gas：
UV(160nm-185nm)+H2S→[H]*+[S]*,O2+UV→[O3]*,[H]*+[S]*+[O3]*→SO2+H20；
UV(160nm-185nm)+C2H6S→[C]*+[H]*+[S]*,O2+UV→[O3]*,[C]*+[H]*+[S]*+[O3]*
→SO2+CO2+H2O；
UV(160nm-185nm)+CH4S→[C]*+[H]*+[S]*,O2+UV→[O3]*,[C]*+[H]*+[S]*+[O3]*
→SO2+CO2+H2O；
From the above reaction, it is seen that the reaction of pre-reaction room includes two aspects：One side is organic exhaust gas ultraviolet
It is cracked under the direct irradiation of ray, forms the atom and radical ion in ionic condition；On the other hand it is high energy ultraviolet ray
The extraneous fresh air entered of irradiation generates the active ozone of property, and ozone carries out Strong oxdiative with the organic exhaust gas after cracking and reacts
Generate the compound of harmless or low evil.
Further, the exhaust gas after optical plasma equipment resolution process enters main reaction region, and main reaction region is predominantly efficient
Aoxidize spray column.Polymeric absorbent oxidant is uniformly sprayed on filler by setting nozzle in spray oxidation furnaces, and exhaust gas passes through
When filler, increase the contact area of exhaust gas and oxidative absorption liquid, increases absorption efficiency.Oxidative absorption liquid uses macromolecule deodorization
Agent, principle are as follows：
With zwitterionic chemical reaction：
Acid, alkalinity, neutral foul smell molecule can all carry out neutralization reaction in deodorant molecular configuration, and deodorant passes through anti-
Cope with a variety of foul smell molecule smelly eliminatings.
With zwitterionic chemical reaction：Acid, alkalinity, neutral foul smell molecule can all carry out in deodorant molecular configuration
Neutralization reaction, deodorant is by reacting to a variety of foul smell molecule smelly eliminatings.Macromolecular deodorizer belongs to supra polymer compound, molecule
It measures up to 20,000,000-3,000 ten thousand (stink odor is the low molecule that molecular weight is less than 300), is the nontoxic transparent viscosity of colorless and odorless
Liquid.Straight lock shape is constituted by carbon atom, the carbon atom of hundreds of straight lock shapes is wound mutually linear structure.Bulk of molecule is unexpectedly
It is so ten thousand times of the 120-180 of ammonia and hydrogen sulfide.Stench and gas with foreign flavor remover are contacted with stink odor, by strong
Stink odor can be adsorbed in micropore within moment and be wrapped up by intermolecular attraction, and one of feature of the remover is exactly this
Kind packet connects the moment reaction of effect.Whether the absorption is acid regardless of foul smell, and alkalinity or neutral all can be adsorbed completely.This suction
A variety of foul smell molecule smelly eliminatings within moment can be because having both sexes in the supra polymer tectosome of the remover by reaction enclosure power
Ion and neutral ion reactive group, acid, alkalinity and neutral foul smell molecule can all carry out neutralization reaction in the molecule, be adsorbed
Various foul smell molecules and the suitable reactive group of package are decomposed purification after being chemically combined, and are not brought at sewage after purification
Reason and secondary pollution.
