Title:
FLUE GAS CONDENSATION WATER EXTRACTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/014769
Kind Code:
A1
Abstract:
A flue gas condensation water extraction system, related to the technical field of flue gas water extraction, comprising a flue gas condensation-end system and a flue gas refrigeration source-end system. The flue gas condensation-end system comprises a desulfurization absorption tower (1), a flue gas purification and condensation tower (2), and a condensed water storage tank (3). The flue gas purification and condensation tower (2) is arranged above the desulfurization absorption tower (1). A flue gas outlet, a water inlet, and a water outlet are provided on the flue gas purification and condensation tower (2). The flue gas refrigeration source-end system comprises a cooling tower (5). The water outlet is connected to the condensed water storage tank (3) via a condensed water downcomer (G1). The water inlet is connected to the cooling tower (5) via a circulating water supply pipe (G3). A condensation circulation water pump (4) is provided on the circulating water supply pipe (G3). The cooling tower (5) is connected to the condensed water storage tank (3) via a circulating water return pipe (G2). The system not only allows further purification of a flue gas in the flue gas purification and condensation tower and further reduced soot concentration and sulfur dioxide concentration, but also completes condensation water extraction with respect to the flue gas treated in a wet-process desulfurization system, thus providing a large volume of water for production, and conserving water resources.
