Description
Technical field
The present invention relates to the efficient absorption recovery and treatment method of organic exhaust gas, particularly relate to the efficient absorption recycling and processing device and the method for volatile organic waste gas in a kind of synthetic leather production process.
Background technology
In the synthetic leather production process, need to use a large amount of volatile organic solvents (like dimethyl formamide (DMF), toluene, xylenes, butanone); The synthetic leather goods that contain a large amount of organic solvents are through high-temperature process the time; These organic solvents all are discharged in the atmosphere as waste gas; Environment is caused severe contamination, also cause huge waste to enterprise.Therefore, take economical and practical waste gas pollution control and treatment technology, develop suitable technological process, make the waste gas qualified discharge of numerous synthetic leather enterprise, and reclaim organic solvent, the raising performance of enterprises has important practical significance.
The development of synthetic leather waste gas pollution control and treatment technology is constantly to change along with the change of synthetic leather technology.General absorption techniques and the adsorption desorption technology of adopting of existing synthetic leather waste gas pollution control and treatment technology.In absorption techniques; The absorption tower is adopted water to absorb as absorbent and is reclaimed the organic solvent in the waste gas, and this method can be removed the DMF in the waste gas preferably, and clearance is about 90%; But the clearance to toluene, xylenes and butanone is very low, far can not reach emission request.Some enterprise adopts the series multistage absorption tower; Circulation absorbs; Although improved the clearance of DMF, because the poorly water-soluble of toluene, xylenes, their clearance does not obviously improve; This does not only reach emission request, causes the exhaust-gas treatment cost to increase substantially owing to having increased absorption equipment simultaneously.For the adsorption desorption technology, its core technology is selected high performance adsorbent exactly for use.It is adsorbent that present industrial adsorption desorption generally adopts granular activated carbon or NACF isoreactivity carbon-based material when handling synthetic leather waste gas.The specific area of granular activated carbon is generally 600～1600m
2/ g, pore-size distribution is wide, and being processed gas will spread from outside to inside, longer through distance, and so adsorption-desorption is all slower, and absorption is saturated easily, so the rate of recovery lower (about 80%), and service life is not long, and operating cost is high.The NACF pore is less, and specific area is big, and it is to lean on intermolecular attractive interaction to adsorb; Chemical reaction does not take place each other, is physical adsorption process, and the direct opening of aperture is outside; Gas diffusion length is shorter, and adsorption-desorption is all very fast, and the rate of recovery is high; Can reach more than 90%, but NACF costing an arm and a leg, is more than ten times of active carbon.In addition, because absorbent charcoal based adsorbent has certain water imbibition, when absorption has the synthetic leather waste gas of certain humidity; The adsorption capacity of absorbent charcoal based sorbing material can sharply descend, and also is because absorptive characteristics make adsorbent in the steam regenerative process; Need carry out long dry run, so not only time-consuming but also cost is high, therefore; A lot of enterprises generally do not carry out desorption and Regeneration Treatment after absorbent charcoal based adsorbents adsorb is saturated, and direct burn processing.In addition, there is inflammable security hidden trouble in absorbent charcoal based sorbing material in practical applications.
In recent years; A kind ofly be connected with transition metal and new material-metal-organic framework materials (MOFs of the mesh skeleton that forms by the organic ligand that contains oxygen or nitrogen; Metal organic frameworks); Owing to have very flourishing pore structure and incomparable huge specific area, and pore structure is regular, the pore size design is adjustable, surface chemistry group modified advantage that conventional adsorbent such as adjustable do not possess, has good application prospects at chemical adsorbing separation, catalytic reaction, environmental protection and energy field.In the MOFs material, with the novel MOFs material-MIL-101 (Cr of chromium ion as metal ligand
