Improved alkali source system of desulfurization process of coking plant

The invention relates to an improved alkali source system of a desulfurization process of a coking plant. The specific technical scheme is as follows: the improved alkali source system of a desulfurization process of a coking plant comprises desulfurizing towers, regenerating towers and an ammonia still and is characterized in that 2-6 desulfurizing towers and 1-4 regenerating towers are arranged in the alkali system of the desulfurization process of the coking plant; the desulfurizing towers are connected in series with the regenerating towers; and a lye tank and multiple alkali metering pumps are additionally arranged on the other side of the ammonia still. According to the alkali source system of a desulfurization process of a coking plant, provided by the invention, the process flow is simple, and the operation is safe and reliable; and by applying the alkali source system, the desulfurization efficiency of raw gas is greatly increased, the production operation environment is improved, the pipeline corrosion is reduced, and thus the pipeline maintenance is reduced.
