Description
Technical Field
[0001] The invention relates to the technical field of coke oven gas desulfurization, and in particular to a device for deeply removing sulfides from coke oven gas. Background Art
[0002] In the process of industrial coke oven gas desulfurization, dry desulfurization and wet desulfurization are usually used to complete the desulfurization operation. Dry desulfurization uses solid desulfurizers (such as iron, zinc, activated carbon, molecular sieves, etc.) to adsorb or remove sulfides in coal gas through chemical reactions, while wet desulfurization is to contact coal gas with liquid desulfurizers to undergo chemical reactions to convert sulfides into soluble sulfides or directly oxidize them into elemental sulfur. In the process of wet desulfurization, it is usually necessary to cool the high-temperature coke oven gas, and then pass the cooled coal gas into the desulfurizer for mixed reaction to complete the desulfurization operation. Wet desulfurization has a high desulfurization efficiency and strong adaptability, and is suitable for treating coal gas with high sulfur content.
[0003] In the existing traditional wet desulfurization process, the problem of insufficient contact between coal gas and desulfurizer often occurs, resulting in low sulfide removal accuracy. In addition, after the coal gas is passed through the desulfurization reagent and then discharged, it will also carry the reagent attached with sulfide, resulting in low desulfurization accuracy of coke oven gas, which is difficult to meet subsequent industrial applications. To this end, we proposed a device for sulfide removal in deep coke oven gas to solve the above problems. Summary of the invention
