Problems solved by technology
[0005] The current common regeneration methods are mainly bubble tower regeneration and trough jet regeneration, such as the regeneration methods described in Chinese patents CN102553413B, CN 103468337B, and CN 202390417U. These regeneration methods have poor mass transfer effects and long gas-liquid contact time, etc. Disadvantages lead to problems such as low regeneration efficiency, large air consumption, bulky regeneration equipment, large liquid circulation, high energy consumption, and degradation of complexing agents in industrial applications.
The new regeneration method represented by electrochemical regeneration has high efficiency, but there are problems such as complex equipment structure, high manufacturing and maintenance costs, such as the regeneration method described in Chinese patent CN103920538A

The invention provides a regenerating device for a complex iron desulfurizer, comprising a cylindrical reactor with an inverted conical bottom, inside which is provided with a coaxial guide tube, and the guide tube divides the inner space of the reactor into: The degassing and settling zone in the draft tube, the sulfur particle enrichment zone and the oxidation reaction zone below the draft tube. The invention also provides a regeneration system and a regeneration method for the complex iron desulfurizer. The invention can significantly improve the gas-liquid mass transfer efficiency of the oxidizing gas, increase the dissolved oxygen in the liquid phase system, the regeneration reaction rate of the complex iron desulfurizer is faster, the reaction is more complete, the regeneration efficiency is obviously improved, and the cost and energy consumption are reduced. It is also greatly reduced; and the equipment has a simple structure and few components, which can avoid the problem of blockage of sulfur particles and can run stably for a long time.
Description
technical field [0001] The invention relates to the field of industrial gas purification, in particular to a regeneration device, regeneration system and regeneration method of a complex iron desulfurizer used for removing hydrogen sulfide. Background technique [0002] In industrial production processes such as natural gas purification, petroleum processing, and coal gasification, the by-products often contain a large amount of hydrogen sulfide (H 2 S) mixture. h 2 S has the characteristics of toxicity, corrosiveness, and stench, which endanger human health, equipment safety, and cause environmental pollution; in addition, H 2 S will also have adverse effects on the storage, transportation and processing of the mixed gas. Therefore, efficient, green and energy-saving H 2 S removal technology is of great significance to energy production and environmental protection. In the past two decades, due to increasingly stringent environmental protection standards, countries hav...
