Abstract

The invention discloses a device for recovering flue gas waste heat and cooperatively eliminating wet smoke plume. The water content of clean flue gas is greatly reduced by the aid of an absorption device, steam releases latent heat owing to phase change when being absorbed by absorption liquid, the dryness and the temperature of the clean flue gas can be improved, colored smoke plume can be eliminated, deep water extraction can be performed, the dust content of the clean flue gas can be reduced, and low-quality latent heat of water vapor in the clean flue gas can be recovered. The absorptionliquid absorbing the water vapor in the absorption device is changed into dilute solution, the dilute solution is conveyed into a regenerating device, exchanges heat with saturated steam generated bythe regenerating device and is regenerated into concentrated solution, the concentrated solution is conveyed into the absorption device, the saturated steam generated after compression of secondary steam at the top of the regenerating device in the regeneration process, the saturated steam releasing the latent heat is changed into condensed water, cost and energy consumption are reduced, and the device has excellent social and economic impact.

Description

technical field

[0001] The invention belongs to the technical field of environmental protection, and in particular relates to a device for recovering waste heat of flue gas and synergistically eliminating wet plume. Background technique

[0002] With the development of my country's economy, in order to actively respond to the "Shanghai Coal-fired Power Plant Gypsum Rain and Colored Plume Test Technical Requirements (Trial)", Zhejiang "Coal-fired Power Plant Air Pollutant Emission Standards" (draft for proposals), Tianjin "Notice on Further Strengthening the In-depth Control of Air Pollution in Key Industries such as Thermal Power and Iron and Steel in Our City" and the regulations for eliminating colored plumes in Tangshan, Zhangjiakou, Handan and other places in Hebei. Various technical routes for recovering flue gas waste heat have been developed. The common technical route is to arrange flue gas condensers, spray towers or add slurry coolers on the slurry circulation slurr...
