As an atmospheric pollution control engineer with 20 years of engineering practice in acidic waste gas treatment, I have led the design of over 300 acidic waste gas treatment systems across various industries including coal-fired power plants, steel smelting, and chemical production. Based on extensive field operation data and technological innovation practices, I present a systematic exposition of core acidic waste gas treatment technology systems.
