Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to an acid and alkali waste gas purification device. Background Technology

[0002] Acid and alkali waste gas refers to gases containing acidic or alkaline substances emitted during industrial production processes. These waste gases are usually generated by chemical reactions, material handling, processing and manufacturing operations.

[0003] At different stages of chemical production, the concentration of acid and alkali waste gas may rise or fall sharply in a short period of time, and may contain complex organic or inorganic impurities. When the concentration of waste gas suddenly increases, the purification device may not be able to adapt quickly, resulting in some waste gas being discharged before it can be treated. Therefore, we propose an acid and alkali waste gas purification device. Utility Model Content
