Description

Technical Field

[0001] The utility model relates to the technical field of battery processing devices, in particular to a waste gas processing device for waste batteries. Background Art

[0002] The waste gas generated during the treatment of used batteries has always attracted much attention. In particular, used lead-acid batteries often produce waste gas containing plastic flakes and corrosive gases during the recycling process. If these waste gases are directly discharged into the environment, they will cause serious pollution and harm to the environment. Therefore, it is very important to effectively treat the waste gas.

[0003] Traditional waste gas treatment devices usually use spraying to treat waste gas. However, there are some defects. For example, plastic flakes in the waste gas are often unable to be effectively separated, resulting in their deposition in the alkaline neutralization liquid, which affects the spraying effect.
