The deficiencies of high, is especially unsuitable for processing exhaust gas tolerance and the big exhaust gas of concentration amplitude of variation.
3, photooxidation method
Photooxidation is depth light degradation technology under room temperature.The technology generates different energy by the UV excitation light source of specific wavelength
The light quantum of amount；Litter is verified the strong absorption of the light quantum, can make exhaust gas substance point under the bombardment of light quantum largely taking
Subsolution from and excitation；Oxygen and moisture and additional ozone in air can produce a large amount of under (decomposition) effect of the light quantum
Hydrogen in statu nascendi, activity (free) oxygen and hydroxyl oxygen isoreactivity group；Because the taken positron-electron of free oxygen is uneven so need to be with
Oxygen molecule combines, and then generates ozone, and the organic matter after ozone decomposes ultraviolet beam irradiation has extremely strong oxidation；
Portion substance can also be reacted with active group, and final Degradation and Transformation is the innocuous substances such as low molecular compound, CO2 and H2O,
To achieve the purpose that purify exhaust gas.
This technique can play a role for the organic exhaust gas of small air quantity, but have certain requirement to pre-treatment,
It is not significant for the VOCs treatment effect of Wind Volume, concentration height and complicated component；Equipment installed power is small, for paint solvent class
The decomposition of VOCs is substantially at no active state；The ozone of generation is unable to fully reacting, can also be easy to cause secondary pollution.

At.
The action process of the utility model is as follows:
Exhaust gas containing VOCs revolves cleaner 1 by high speed sucking water, revolves the centrifugal force in cleaner by water and acts on, paint
From being adsorbed on separation to moisture film in air stream, water is separated the particulate matters such as mist, dust by baffle, prevents from spuing from exhaust outlet,
And coating cloud, dust are collected into waste residue slot through return flume.This link can remove the particulate matters such as 99% coating cloud, dust in removing exhaust gas,
Exhaust gas after processed enters spray absorber 3 by vent and air hose, and exhaust gas forms gas rotation after spiral board 301
Stream, can be such that gas-liquid two-phase comes into full contact with；Packing layer 302 increases gas-liquid contact time, keeps waste gas absorption more thorough, spray head exists
The uniform spray-absorption liquid of spraying layer 303, improves absorption efficiency, and demisting layer 304 prevents absorbing liquid from being taken out of by gas, reduces absorption
The consumption of liquid；Exhaust gas is discharged after spray absorber 3, in discharge process, discharges 5 continuous automatic inspection of on-Line Monitor Device
The concurrent inspection measured data of parameters such as the concentration of exhaust gas are discharged to server.
After wherein the waste residue in water rotation cleaner 1 in waste residue slot is dried in vacuo using waste residue Minton dryer 6
Reason, is heated, the moisture in waste residue is evaporated, and flows to vacuum pump at gaseous state, water is cooled in pump by heat pump of high-temp water source
Water tank is drained into, remaining gas drains into spray absorber by two-stage vacuum pump.Using de- after absorbing liquid saturation in liquid reserve tank
Attached 7 desorption and regeneration of regenerating unit forms new absorbing liquid, and (boiling point of absorbent is 280 degree or so, general to have for recycling
The boiling point of solvent is more than 100 to spend, according to this boiling-point difference, using reduced pressure distillation process VOCs component from saturated absorption liquid
In parse, absorbent complete regeneration, while the VOCs parsed directly regeneration equipment burning provide heat).
Embodiment described above is only that the preferred embodiment of the utility model is described, not to the utility model
