AI Technical Summary

⚠Technical Problem

In existing wet desulfurization processes, the desulfurizing agent in the circulating water cannot be reduced after reaction, leading to sulfur enrichment in the circulating water and excessive sulfur dioxide levels at end users.

⚗Method used

A blast furnace gas desulfurizer regeneration device is adopted, which includes a buffer chamber, a reaction chamber, and a conveying chamber inside the regeneration box. FeS precipitate is generated by the reaction of circulating water with iron salt, which reduces the sulfur content in the circulating water, and a secondary reduction treatment is carried out in the reduction chamber.

🎯Benefits of technology

The desulfurizing agent in the circulating water was regenerated, which reduced the sulfur content in the circulating water, improved the desulfurization efficiency of the circulating water, and solved the problem of sulfur enrichment in the circulating water.
