Operation principle:Ring amine tail gas is entered by air inlet pipe 101 in spray column 1, gas by tower lower part air inlet into
Entering in tower and moves upwards, the dilution heat of sulfuric acid of 1 bottom of spray column is introduced into the heat exchange cooling of condenser 3 by circulating pump 2, so as to
Best assimilation effect is kept, then enters the helical form spray equipment 102 of 1 top of spray column by pipeline, by being uniformly distributed
After be sprayed on stainless steel corrugated filler layer 103, the contact area of tail gas and dilution heat of sulfuric acid can be increased, make gas and drop
It comes into full contact with, mass transfer enhancement efficiency, achievees the purpose that the dedusting that cools down;The part hexamethylene amine gas in tail gas can be quickly dissolved in simultaneously
In dilution heat of sulfuric acid, dilution heat of sulfuric acid can be discharged through controlled valve 104 after recycled for multiple times and is collected to it, so
Cyclohexylamine is separated by Distallation systm afterwards, carries out recycling;Gas after treatment goes out from 1 top of spray column
Feed channel is discharged and flows through demister 4 with certain speed, and tail gas enters light after demister 4 reaches demisting drying by pipeline
Oxygen catalytic oxidizer 5, after the effective filter 501 being arranged by front end filters out macromolecular, using photocatalyst device 502
Collaboration is carried out in ultraviolet photolysis cavity 503 decomposes oxidation reaction:It is ultraviolet in the case where nanoscale is catalyzed the catalysis reaction of module 505
The high-energy photon light beam of lamp group 504 and ozone, the OH (hydroxyl radical free radical) of air reaction generation carry out the exhaust gas components such as amine
Oxidation-reduction reaction, while macromolecular gas makes its chain structure be broken under high-energy photon effect, makes most of organic gas object
Matter is converted into micromolecular compound or the permineralization of odorless, generates water and CO2.Treated tail gas dress treated by ozone
6 removal ozone are set, prevents ozone from getting into the air and pollutes air, then passes through air blower 7 and enters the discharge of chimney 8.
The ozone treatment apparatus 6 is equipped with ring amine detector 9 with 7 connecting pipe of air blower, passes through ozone in tail gas
Processing unit 6 is removed after ozone excludes and is detected by ring amine detector 9, and detection data is transferred to controller 11, controller 11
