During the rubber desulfurization process, tail gas containing sulfides is usually produced. These sulfides are mainly hydrogen sulfide (H2S) and sulfur dioxide (SO2). When the sulfides in the rubber are desulfurized, the sulfides will be adsorbed, converted or oxidized into other forms and discharged into the atmosphere. These treated tail gases usually contain sulfide gas products, which will have a negative impact on the environment and human health. Traditional tail gas treatment equipment is usually centralized treatment. Centralized treatment requires the installation of large-scale treatment equipment to transport the tail gas to the treatment equipment through pipelines for treatment. However, large-scale treatment equipment lacks tail gas pre-treatment procedures, and large-scale treatment equipment often fails, and maintenance is cumbersome. Utility Model Content
