[0002] H2S is widely present in many industrial raw gases or exhaust gases such as natural gas, coke oven gas and biogas. H2S not only affects human health, but also corrodes equipment and pipelines, seriously affecting normal production and life. H2S has a poisoning hazard to catalysts in chemical production. Therefore, removing H2S is very necessary and is also a necessary link in many chemical process processes.

However, current desulfurization devices generally adopt the form of an integral fixed bed or skid-mounted structure, which is extremely inconvenient when the desulfurizer is frequently replaced, seriously affecting the desulfurization efficiency.
