摘 要 超重力机作为一种新型、高效的强化传质设备，已被广泛用于化工分离与纳米材料制备领域。超重力湿法高精度脱除低浓度煤气中的硫化氢的成功运行，有望替代传统干法脱除的工艺可以广泛应用于煤气天然气等工业气体中的脱硫超重力技术能高效率脱除高浓度这样的技术指标和运行成本是传统脱硫塔技术远远达不到的高精度脱除天然气中的硫化氢技术基本达到干法精脱硫的效果但其经济技术指标明显优于干法技术因此超重力应用到天然气气水煤气作业出以及 Abstract As a kind of new and highly efficient mass transfer equipment, the super gravity machine has been widely used in the field of chemical separation and preparation of nano materials. High precision removal of hydrogen sulfide from low concentration gas by high gravity wet process is expected to replace the traditional dry process. Can be widely used in gas, gas, and other industrial gases in the desulfurization. High gravity technology energy efficient removal of high concentration system in high concentration, such technical indicators and the running cost is the traditional technology of desulfurization tower fell far short of the; high precision removal from natural gas hydrogen sulfide technology, basically reached the dry desulfurization effect, but its economy and technology refers to indicate significantly better than dry technology. Therefore, there is reason to believe that high gravity apparatus can be widely used in natural gas, refinery gas, synthesis gas, gas and other gas hydrogen sulfide removal, will bring obvious economic benefit and social benefit. This article is in collecting hyper gravity machine in a rotating packed bed (RPB) design, calculation, analysis and use of data base, with reference to the now high gravity machine the design theory and method, to complete the structural design of high gravity machine.
