Hydrogen sulfide waste gas treatment uses spray tower equipment. This equipment has small resistance, low energy consumption, low noise, and high treatment efficiency. It can handle hydrogen chloride gas (HCL), hydrogen fluoride gas (HF), Ammonia gas (NH3), sulfuric acid mist (H2SO4), chromic acid mist (CrO3), hydrocyanic acid gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (H2S), sulfur dioxide (SO2) gas and formalin (HCHO) and other gases.
