Abstract

The invention discloses a comprehensive treatment system for desulfurized flue gas and a treatment method adopting the comprehensive treatment system and belongs to the field of environmental protection equipment. The treatment system comprises a boiler assembly, a dry type dust collector, an induced draft fan assembly, a waste heat recovery heat exchanger, a desulfurizing absorption tower, a phase change dust collector, a gas-gas heater and a chimney which are connected sequentially. The comprehensive treatment system is simple in structure, adopts simple principle, perfect desulfurization offlue gas is realized through coordination of all parts, 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 comprehensive treatment system for desulfurization flue gas. 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 utiliza...
