Acid Fume treatment Of Hot Dip Galvanizing Room

Acid fume close room

Acid fume close room

Acid mist absorber

1.The acid fume during pickling is drawn to the absorption tower by the induced draft fan through the channel

2.Using 1 water spraying + 1 alkali spraying system in series for purification treatment.

3.The first tower uses water spraying to clean 80% acid fume to generate dilute hydrochloric acid, which can be used to clean jigs. The reaction between dilute hydrochloric acid and zinc on jigs can produce ZnCl2, which can be used to make flux agent.

4.The second tower is sprayed with alkali liquor, and the remaining acid is neutralized and Compliance discharge.

5.Packing material is put in the tower to increase the contact area between water mist and acid fume, so as to achieve better washing effect.

6.The absorption tower and pipeline are made of PP material, welded by heat fusion, connected by casing, and external are strengthened by welding of PPmaterial flange.

7.Fans use negative pressure to extract the acid fume.

8.The acid fume is discharged outward through chimneys.
