Abstract

The invention discloses coke oven gas desulfurization equipment which belongs to equipment for removing sulfuretted hydrogen from ammonia and sulfuretted hydrogen-containing gases, and in particular relates to equipment for removing the sulfuretted hydrogen from coke oven gases. The coke oven gas desulfurization equipment has a structure that the coke oven gas desulfurization equipment mainly comprises a coal gas indirect cooler, a desulfurizing tower and a regenerating tower which are connected together through pipelines, the connection relationship of the devices is that a coal gas outlet of the coal gas indirect cooler is connected with a coal gas inlet on the bottom of the desulfurizing tower, a desulfurizing liquid nozzle is arranged on the top of the desulfurizing tower, a purified coal gas outlet is formed on the upper part of the desulfurizing tower, a desulfurizing liquid outlet on the bottom of the desulfurizing tower is connected with the regenerating tower through a solution circulating tank and a pump, a regeneration desulfurizing liquid outlet is formed on the upper part of the regenerating tower and is connected with the desulfurizing tower through a desulfurizing liquid circulating pipeline, a tower cover which contains a sulfur and foam separation device is arranged on the top of the regenerating tower, and a sulfur foam outlet is formed on the bottom of the tower cover. The coal gas indirect cooler is adopted to cool coal gas to 20-22 DEG C before desulfurization, the structure of the desulfurizing tower is improved, and the desulfurizing efficiency is increased.

Description

technical field [0001] The invention belongs to equipment for removing hydrogen sulfide from gas containing ammonia and hydrogen sulfide, in particular to equipment for removing hydrogen sulfide from coke oven gas. Background technique [0002] One of the traditional technologies for removing hydrogen sulfide from coke oven gas is the wet oxidation desulfurization technology using ammonia as an alkali source. The mass concentration of ammonia in coke oven gas is only 5-7g / m 3 , while the mass concentration of hydrogen sulfide is mostly in the range of 5-10g / m 3 . Due to the low mass concentration of ammonia, the desulfurization efficiency is reduced, generally only 92-95%. The hydrogen sulfide content in the gas after removal is generally 250-400mg / m 3 . In the "Coking Chemical Industry Pollutant Discharge Standard" (GB16171-2012), which came into effect on October 1, 2012, the emission concentration limit of air pollutants from existing enterprises stipulates that the ...
