Abstract

The invention discloses a flue gas desulfurization method and flue gas desulfurization equipment, and aims to solve the technical problem of helping to improve the flue gas purification effect of catalytic flue gas desulfurization. The flue gas desulfurization method comprises the following steps: introducing target flue gas into a cooling system, so that the target flue gas is cooled by spraying liquid; introducing the cooled target flue gas into a desulfurization system, so that the target flue gas is desulfurized through a catalyst, and sulfur dioxide removed in the desulfurization system forms sulfuric acid on the catalyst and enters regeneration liquid for washing and regenerating the catalyst along with washing and regeneration of the catalyst, wherein the spraying liquid is from the regeneration liquid. The target flue gas is cooled through the spraying liquid, so that the dust content in the target flue gas can be reduced, and the target flue gas can reach a catalytic activity temperature interval required by the catalyst conveniently; as the spraying liquid comes from the regeneration liquid, the concentration of the spraying liquid can be increased, and subsequent utilization of the spraying liquid is facilitated.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization, in particular to catalytic flue gas desulfurization technology, and more specifically to a flue gas desulfurization method and flue gas desulfurization equipment using the catalytic flue gas desulfurization technology. Background technique [0002] Catalytic flue gas desulfurization technology is a known desulfurization technology with great application prospects. Its basic principle is: sulfur dioxide, water, and oxygen in the flue gas are adsorbed on the catalyst and react under the catalysis of active components. This produces sulfuric acid. When the sulfuric acid attached to the catalyst reaches a certain level, the catalyst is washed with a regeneration solution (usually dilute sulfuric acid and / or water) to remove the attached sulfuric acid on the catalyst and release the active sites of the catalyst. The used regeneration solution can be reused as a by-product (usually di...
