复合铁离子的作用是将吸取反应中产生的电子释放到再生反应中。由于每个单质硫消耗两个铁原子,因此在反应过程中至少提供了两个铁原子。所以铁是反应物。然而,铁离子作为硫化氢和氧气的催化剂,在整个反应中不会被消耗。因此,铁离子配合物通常被定义为催化剂。
The function of compound iron ions is to release the electrons produced in absorption reaction into regeneration reaction. Since each elemental sulfur consumes two iron atoms, at least two iron atoms are provided during the reaction. So iron is a reactant. However, as the catalyst of hydrogen sulfide and oxygen, iron ion will not be consumed in the whole reaction. Therefore, iron complexes are usually defined as catalysts.
该系统采用碱性复合铁催化剂的氧化还原性能来吸取酸性气体中的H2S。H2S被络合铁直接氧化形成单质硫,络合铁被转化为络合亚铁,通过蓄热式沉淀池泵入空气中。将空气中氧氧化碱性吸取塔中的络合亚铁转化为络合铁进行循环利用。同时,将硫磺沉降分离到再生沉淀池中,形成硫磺浆,送入过滤器脱水成硫磺饼。铁的方法的特点是使用复杂的催化剂具有高硫能力,这不仅适用于治疗的原料气体含硫量高,但也有一个小的循环液体体积,小型设备的大小,并且可以直接生成单质硫存在二次污染的问题。
The system uses the redox performance of basic composite iron catalyst to absorb H2S in acid gas. H2S is directly oxidized by complex iron to form elemental sulfur, and complex iron is converted into complex ferrous, which is pumped into the air through the regenerative sedimentation tank. The complex ferrous iron in the oxygen oxidation basic absorption tower in the air is converted into complex iron for recycling. At the same time, sulfur deposition is separated into regeneration sedimentation tank to form sulfur slurry, which is sent to filter for dehydration to form sulfur cake. The feature of iron method is that the complex catalyst has high sulfur capacity, which is not only suitable for the treatment of raw gas with high sulfur content, but also has a small volume of circulating liquid, the size of small equipment, and can directly generate elemental sulfur with secondary pollution.

含硫废气处理可采用鼓泡喷淋联合塔工艺。在这个系统中,吸取剂和氧化剂被集成到一个设备中,从而减少了一个容器,并消除了对溶液循环泵和相关管道的需要。复合铁脱硫技术在脱除硫化氢和氧化挥发性有机物方面具有独特的实用价值,该技术可以节省设备投资,而且脱氨、脱硫氢、有机硫和氧化其他挥发性有机化合物具有独特的优势。相信该技术将很快在各个领域的有机废气处理技术中脱颖而出。
The process of bubbling spray combined tower can be used for sulfur-containing waste gas treatment. In this system, absorbent and oxidant are integrated into one equipment, thus reducing one container and eliminating the need for solution circulating pump and related pipelines. The compound iron desulfurization technology has unique practical value in the removal of hydrogen sulfide and oxidation of volatile organic compounds, which can save equipment investment, and has unique advantages in the removal of ammonia, desulfurization of hydrogen, organic sulfur and oxidation of other volatile organic compounds. It is believed that this technology will soon stand out in various fields of organic waste gas treatment technology.
