Abstract

The invention discloses a seawater desulfurization auxiliary equipment system and a desulfurization method. The system comprises a dust removal device 1, an air separation device 2, a nitrogen compressor 3, a GLS (Gas-Liquid-Solid Chromatograph) seawater heat exchanger 4, a siphon well 5 and an absorption tower 6, wherein the air separation device 2 is connected with the nitrogen compressor 3, the dust removal device 1 and the GLS seawater heat exchanger 4 respectively; the GLS seawater heat exchanger 4 is connected with the absorption tower 6 and the siphon well 5 respectively. By utilizing the air separation device and the nitrogen compressor, most nitrogen gas is enriched; on one hand, the enriched nitrogen gas can be used for other purposes and comprehensive utilization of seawater is realized; on the other hand, internal pressure of flue gas is reduced and accurate control on flow speed of the flue gas is realized; then by utilizing the GLS seawater heat exchanger, the flue gas exchanges heat with circulation seawater entering a heat exchange device, and the temperature of the flue gas is controlled to be an optimal absorption temperature, so that the desulfurization efficiency is improved, the desulfurization time is shortened, and the electricity consumption in operation is reduced.

Description

Technical field [0001] The invention relates to a seawater desulfurization auxiliary machine system and a desulfurization method, and belongs to the technical field of flue gas desulfurization. Background technique [0002] Seawater flue gas desulfurization technology is a method of using the alkalinity of seawater to remove sulfur dioxide from flue gas. When performing seawater desulfurization, the usual method is to directly pass the flue gas into the seawater, and use a large amount of seawater for absorption to reduce The sulfur content in the flue gas (such as "a sintering flue gas seawater desulfurization process and desulfurization system" disclosed in the invention patent application No. 201010291585.9). However, the existing seawater desulfurization technology still has the following shortcomings: [0003] 1. The amount of seawater used for desulfurization is large, the purpose is single, and the desulfurization speed is slow and the efficiency is low; [0004] 2. The spra...
