Description
Technical field
A kind of exhaust gas processing device for cefixime side chain active ester production is the utility model is related to, belongs to chemical industry
Technical field of waste gas treatment.
Background technology
Can produce substantial amounts of waste gas in the production process of cefixime side chain active ester, the constituent species in waste gas compared with
It is more, concentration is higher, mainly contain the compositions such as acetonitrile, methanol, triethylamine, pyridine, can not only pollute air ambient in discharge process,
Tail gas, which runs into naked light, electrostatic, simultaneously can also produce the danger of fire explosion；Simultaneously because of volatile components (acetonitrile, the first in waste gas
Alcohol) content is higher, and directly discharge, not only cause the waste of resource, also do not meet the regulation of national energy-saving emission reduction.In addition it is current
Safety and environmental protection situation is increasingly serious, and waste gas absorption, which just becomes, to be solved the problems, such as.
Utility model content
The purpose of this utility model is to provide a kind of exhaust gas processing device for cefixime side chain active ester production,
With the characteristics of simple in construction, easy to operate, vent gas treatment effect is high, treatment effeciency is high, suitable for handling exhaust gas flow velocity
What greatly, constituent was complicated efficiently separates operating mode.
Exhaust gas processing device described in the utility model for cefixime side chain active ester production, including charging are slow
Rush tank feed surge tank and be sequentially connected cyclone separator, absorption tower, receiving tank and condenser, the outer wall of feed surge tank be provided with into
Gas port, air inlet connection feed pipe.
Wherein：
The air inlet is located at feed surge tank 2/3 and highly located, and is arranged such and is more beneficial for the larger liquid of proportion
Or solid granule is settled down to feed surge tank tank bottom, realizes and be separated with the light component in tail gas；The feedstock direction of feed pipe
Tangent with feed surge tank, being arranged such can reduce that tail gas is caused in itself to tank body when entering feed surge tank to be rushed as far as possible
Hit power.
The condenser is located at the top of receiving tank.
The absorption tower is packed absorber, filler preferably ceramic filler or wire packing, and such filler is corrosion-resistant, uses
Time is grown, and can further separate the weight component in tail gas, and the ejecting liquid of packed absorber is acidic liquid, to inhale
The alkaline matter such as contained triethylamine, pyridine in ending gas.
The receiving tank is provided with cooling jacket, and tail gas is fully condensed, condenses insufficient tail gas and then enter after entering
Enter to be located at the efficient condenser on receiving tank top, enter receiving tank again after condensation.
Operating process is as follows：
By caused tail gas in cefixime side chain active ester production process in the presence of induced draught system, pass through charging
Pipe enters feed surge tank with certain flow velocity by charging aperture, and solid granule and partially liq sink under gravity
Drop, realizes the initial gross separation of weight component, and light component enters cyclone separator, further realizes the separation again of weight component,
The light component being then demultiplex out enters packed absorber, carries out absorption and separation to basic component contained therein, remaining ingredient enters
Enter receiving tank and carry out condensation recovery, it is impossible to which a small amount of tail gas of condensation is back to reception again after entering efficient condenser condensation recovery
Tank.
The beneficial effects of the utility model are as follows：
Acetonitrile in tail gas, methanol equal solvent class tail gas can be condensed back using processing unit of the present utility model
Receive and utilize, having saved the alkaline matter such as resource, triethylamine, pyridine can also carry out neutralizing absorption processing by absorption tower, a whole set of
Device combination is simple, and tail gas has obtained abundant processing, reasonable in design, safety and environmental protection.
