Abstract
The invention relates to a purifying device for washing organic gas in low-temperature and wet-type ways. The purifying device comprises a washing tower, an oxidation treatment unit and a catalyst adsorption unit, wherein the washing tower is used for receiving organic gas and transmitting organic pollutants in the organic gas into washing liquid; the oxidation treatment unit is used for treating the washing liquid of the washing tower and leading oxidizing agent into the washing liquid for oxidation reaction, and the oxidation treatment unit further comprises a circulating water pump for pumping the washing liquid to be purified, an oxidizing agent container used for storing the oxidizing agent to be added, and a mixer used for mixing the oxidizing agent and the washing liquid; and the catalyst adsorption unit provides a porous catalyst adsorption bed so as to accelerate the oxidation of the oxidizing agent. In the purifying device, organic pollutants are transferred into the liquid-phase washing liquid from the gas phase, and then the pollutants in the washing liquid are further effectively purified, treated and controlled according to the concentration of the pollutants in the washing liquid, thereby the consumption of the washing liquid can be reduced, the gas leakage amount of the pollutant in the washing liquid is reduced, and the treatment efficiency of the organic pollutants can be promoted.
Description
Technical field
The present invention relates to a kind of purifier, particularly relate to a kind of purifier of washing organic gas in low-temperature and wet-type ways.
Background technology
Progress along with science and technology, semiconductor processing procedure live width size constantly requires to drop to 40 or 65 how below the rice, and then after how entering the metric system journey epoch, demand focus for high-order manufacture of semiconductor clean room environment pollutant, be transferred to the organic gas molecule in space pollutant of more unmanageable volatility (AMC from the gas molecule in space pollutant of known microparticle pollution and inorganic acid alkali, Airborne Molecular Contamination), on the acceptance rate of the product of the large scale TFT-LCD that causes in high-order processing procedure wafer factory and similar techniques (Thin-Film Transistor Liquid-Crgstal Display) panel factory promoted, the control of the organic gas molecule in space pollutant of this volatility had been one of each big factory key technology.
Except manufacture of semiconductor, all continue to face the problem of similar organic gas molecular contamination in living environment face, operating environment safety and environmental protection etc., also therefore the use of organic gas purification technology is more and more general.Contain a large amount of volatile organic matters (volatile organic compounds in the TFT-LCD panel factory of manufacture of semiconductor wafer factory and similar techniques and the makers' waste gas of solar chip, VOCs), as alcohols: isopropyl alcohol (IPA), n-butanol (NBA), alcohol ether; Ether-ether class: propylene glycol monomethyl ether ethyl ester (PGMEA), propylene glycol monomethyl ether (PGME); Ketone: acetone (acetone), butanone (MEK), cyclohexanone (cyclohexanone); Ester class: ethyl acetate (EAC), n-butyl acetate (NBAC); Benzene class: toluene (TOL), dimethylbenzene (XYL); Organic sulfur compound: DMS, DMDS, acetic acid and part high boiling substance, as monoethanolamine (MEA, monoethanolamine), dimethyl sulfoxide (DMSO) (DMSO, Dimethylsulfoxide), buffered deoxycholate glucose (meat soup), N-methyl pyrrolidone (N-Methyl Pyrrolidone) etc.
The commercialization technology that present processing semiconductor contains VOCs (Volatile Organic Compounds) waste gas mainly is to be that runner concentrates incineration technology, active carbon adsorption technology and wet scrubbing technology.Runner concentrates incineration technology palpus consume fuel; The active carbon adsorption technology then must often be changed activated carbon, and the two running cost all has too high problem.The semiconductor dealer uses runner to concentrate and incinerates scientific discovery at present in addition, this technology is relatively poor to the removal effect of the stench organic compound (as acetic acid) of high boiling substance (as the main component of removing photoresistance agent) and low concentration low odor threshold value, and can destroy the adsorption capacity of the employed sorbing material of concentration runner, and cause to continue to reduce the treatment effeciency of removing pollutant.
The characteristic of organic gas molecule in space pollutant is different from the gas molecule in space pollutant of micronic dust particle and inorganic acid alkali, so the mechanism of handling can be completely different, and difficulty is also higher relatively.Organic gas molecule in space pollutant control technology develops for many years in the air, but is partial to the treatment technology of high concentration mostly, and is still not obvious for its effect of low concentration person.
For water-soluble high VOCs (Volatile Organic Compounds) composition, generally can the mat washing technology it be transferred to the processing that liquid phase is carried out pollutant again from gas phase, still quite big for the water yield of keeping treatment effeciency.Can further utilize the oxidation rinsing mode that the waste gas organic substance is transferred in the water, the fiting chemical oxidation is divided into carbon dioxide, water or harmless salt with water pollutant, make washings can reclaim use again, too slow or have and produce the higher material of harmfulness and residue in doubt in the waste water but general oxidant is subject to reaction rate.
The oxidizing force of ozone is splendid, and is a lot of in the application of running water and wastewater treatment, is commonly used to sterilization or removes partial organic substances.Ozone and organic reaction approximately can be divided into ozone and water pollutant and directly react (direct reaction), produce hydroxyl free radical (OH radical) and carry out indirect reaction (indirect reaction or radical-type reaction) two parts with water pollutant.Utilize ozone and H
2O
2, reactions such as UV, OH-produce OH radical participate in the oxidation reaction technology be commonly referred to as high-level oxidation technology (Advanced Oxidation Processes, AOP).
