Refering to fig. 1 and Fig. 2, the invention proposes a kind of dresses using acid etching electrolysis system vent gas treatment ammonia nitrogen water
It sets, including ammonia nitrogen adjusts cylinder 100, ammonia nitrogen adjusts cylinder 100 and is equipped with ammonia nitrogen water inlet 101, buck import 102, exhaust outlet 103 and row
Liquid mouth 104.It includes cylinder body 110, agitating device 120 and the first reflux line 130, nitrogen water inlet 101, alkali that ammonia nitrogen, which adjusts cylinder 100,
Water inlet 102 and exhaust outlet 103 are set to 110 top of cylinder body；Agitating device 120 include stirring motor 121, mounting base 122 and with
Stirring motor is driven the rabbling mechanism 123 of axis connection, and mounting base is installed on 110 top of cylinder body, and stirring motor 121 is installed on installation
Seat 122, to 110 internal stretch of cylinder body, rabbling mechanism 123 is used to stir the liquid in cylinder body 110 rabbling mechanism 123.First time
Flow tube road 130 is successively arranged jet pump 131 and ejector 132, and jet pump 131 is connected to 110 bottom of cylinder body, ejector 132 with
It is connected at the top of cylinder body 110, ejector 132 is equipped with inlet exhaust gas 132a, is equipped with motor-driven valve at inlet exhaust gas.
Due to containing the compositions such as salt acid mist, chlorine in acid etching electrolysis system tail gas, wherein chlorine be it is a kind of have stop up
The toxic gas of breath formula can cause damages to human health, it is contemplated that when the leakproofness deficiency of rabbling mechanism 123 and cylinder body 110
Chlorine can leak, and to mounting base 122, there are security risks, therefore set a branch pipe 103a in exhaust outlet 103 and enable exhaust outlet 103 and installation
Seat 122 is connected to, and the chlorine to leak to mounting base 122 is led to exhaust outlet 103 and is discharged.
Device using acid etching electrolysis system vent gas treatment ammonia nitrogen water of the invention is set by adjusting cylinder 100 in ammonia nitrogen
Set the first reflux line 130, ammonia nitrogen water enters ammonia nitrogen from ammonia nitrogen water inlet 101 and adjusts cylinder 100, and buck is from buck import 102
It enters ammonia nitrogen and adjusts cylinder 100, the liquid that ammonia nitrogen adjusts cylinder 100 forms first between the first reflux line 130 and cylinder body 110
Liquid circulation, the first reflux line 130 are equipped with ejector 132 and jet pump 131, and ejector 132 is equipped with inlet exhaust gas 132a,
For jet pump 131 by liquid pumping in cylinder body 110 to ejector 132, the 2200W of 380V, ejector 132 is can be used in jet pump 131
Liquid injection is gone out to generate tiny bubble, mainly contains the acid etching electrolysis system tail gas of salt acid mist, chlorine ingredient from tail
Gas import 132a enters ejector 132 and incorporates in tiny bubble, and subsequent tiny bubble is again with liquid in the first reflux line 130
Body is back in cylinder body 110, thus reaches acid etching electrolysis system tail gas and mixing liquid is sufficiently mixed effect.In blender
Under the stirring of structure 123, ammonia nitrogen water, buck and acid etching electrolysis system tail gas generate chemical reaction generate nitrogen.Part is not
The acid etching electrolysis system tail gas and ammonia nitrogen of reaction adjust the nitrogen that reaction generates in cylinder 100 and are discharged from exhaust outlet 103, ammonia nitrogen
The waste liquid adjusted in cylinder 100 is discharged from leakage fluid dram 104.
Specific operating process are as follows: ammonia nitrogen water enters ammonia nitrogen tune from the ammonia nitrogen water inlet 101 that ammonia nitrogen adjusts 100 top of cylinder
It saves in cylinder 100, if a default liquid level, for example, default liquid level is that ammonia nitrogen adjusts 2/3rds of cylinder height, when ammonia nitrogen water reaches pre-
If starting stirring motor 121 opens stirring when liquid level, buck adjusting ammonia nitrogen is added from buck import 102 and adjusts liquid in cylinder 100
PH value, when ammonia nitrogen adjust cylinder 100 in liquid pH value between 8~10 when, stopping be passed through ammonia nitrogen water and buck, unlatching is penetrated
Stream pump 131, and it is passed through acid etching electrolysis system tail gas from inlet exhaust gas 132a, continue to stir, maintains pH value 8~10, ORP big
In 540mV, and reacts and be greater than 1h.Exhaust outlet 103 is then turned on, ammonia nitrogen is adjusted into the exhaust gas in cylinder 100 from 103 row of exhaust outlet
Out, it opens leakage fluid dram 104 waste water in ammonia nitrogen adjusting cylinder 100 is discharged from leakage fluid dram 104.Here, can cooperate as needed from
The metal ions such as the copper in son exchange pretreatment ammonia nitrogen water adjust the generation precipitated in cylinder 100 to reduce ammonia nitrogen, and buck uses hydrogen
When sodium hydroxide solution, it is as follows that ammonia nitrogen adjusts the chemical reaction occurred in cylinder 100:
Cl2+ NaOH=NaClO+NaCl；
3NaClO+2NH3=3NaCl+N2↑+3H2O。
Device using acid etching electrolysis system vent gas treatment ammonia nitrogen water of the invention without using ammonia nitrogen removal agent, and
It is to reduce the improvement of ammonia nitrogen water and acid etching electrolysis system tail gas using acid etching electrolysis system vent gas treatment ammonia nitrogen water
Cost achievees the effect that the comprehensive treatment and the treatment of wastes with processes of wastes against one another of ammonia nitrogen water and acid etching electrolysis system tail gas, and present device
