Background

Most of chlorine gas generated in the process of electrolytic copper cyclic utilization by acid etching of circuit board packaging substrate circuits and the like is recycled by etching lines, but when an etching machine stops production, about 10% of chlorine gas cannot be used due to the fact that the electrolytic lines cannot stop production, and the chlorine gas is discharged after the chlorine gas is required to be treated and reach the standard. The process utilizes the process principle of copper etching, adopts copper as a raw material to absorb residual chlorine, and the tail liquid generated by absorption is circulated back to an electrolysis workshop for electrolysis. The generated chlorine gas is returned to the etching machine for reuse, and the process is repeatedly circulated.

In the process of chlorine absorption treatment, the traditional process for absorbing chlorine by ferric trichloride or liquid alkali has the following problems:

1. when ferric trichloride is used for absorbing chlorine, the generated byproduct ferric trichloride liquid cannot reach the commodity standard and cannot generate value; when the waste water is discharged to a waste water station for treatment, a large amount of alkali is consumed, and simultaneously, the sludge of the waste water station is increased;

2. when liquid alkali is used for absorbing chlorine, the generated byproduct of rinsing water cannot reach the commercial value; the general wastewater station with strong oxidizing property can utilize a small part of the wastewater, and the wastewater station can not process or load the wastewater when the wastewater station is large, so that the biochemical system can be paralyzed;

3. in order to increase the spraying density of the absorbent and to improve the efficiency of chlorine absorption when spraying the absorbent, it is common to spray the absorbent using a plurality of spray pipes or a plurality of spray heads, such as (publication No. CN201510838U) a chlorine absorber, (publication No. CN102974208A) a chlorine-containing off-gas purification apparatus having a function of treating regenerated residual chlorine, and (publication No. CN207856652U) a chlorine treatment facility.
