Abstract

The invention discloses a desulfurization flue gas treatment method, and belongs to the field of environmental protection equipment. The desulfurization flue gas treatment method is realized by a desulfurization flue gas treatment system. The desulfurization flue gas treatment system comprises a boiler component, a dry dust collector, an induced draft fan component, a waste heat recovery heat exchanger, a desulfurization absorption tower, a phase change dust collector, a flue gas heat exchanger and a chimney which are connected in sequence. The structure and principle of the desulfurization flue gas treatment system are simple, the perfect desulfurization flue gas treatment is realized through the cooperation of each part, and the treatment effect is good.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to a desulfurization flue gas treatment method. Background technique [0002] Desulfurization generally refers to the process of removing sulfur from fuel before combustion and before flue gas emission. It is one of the important technical measures to prevent and control air pollution. SO2 in coal-fired flue gas has become the main cause of air pollution, and reducing SO2 pollution has become an urgent task for atmospheric environmental governance. Many flue gas desulfurization processes have been widely used in industry, and it also has important practical significance for the treatment of exhaust gas from various boilers and incinerators. [0003] The currently used desulfurization system generally only desulfurizes alone, and cannot realize the systematic treatment of the flue gas after desulfurization. The heat recovery and utilization of the flue g...
