Abstract

The invention provides a folded plate type gas liquid dividing device, and in particular relates to a novel gas liquid dividing device suitable for a single-tower double-circulation system. The folded plate type gas liquid dividing device comprises a cylinder body; a plurality of flow guide plates are fixedly arranged in the cylinder body sequentially; an annular liquid collecting groove is formed below the flow guide plates; the cross section of each flow guide plate is shaped like a broken line, and each flow guide plate is provided with at least one V-shaped part and at least one reverse V-shaped part; projections of the reverse V-shaped part of one of the adjacent two flow guide plates and the V-shaped part of the other one of the adjacent two flow guide plates in the vertical direction are partially overlapped or completely overlapped. A plurality of flow guide plates with special shapes form a flue gas channel, and when flue gas treated by a primary circulation loop, liquid drops in the flue gas is separated from the flue gas and return to a slurry accommodating pool in an absorbing tower, so primary circulation slurry and secondary circulation slurry can be effectively separated, and the desulfurization efficiency of secondary circulation is improved; the advantages of simple structure, convenience and quickness in mounting, small resistance loss and the like are achieved.

Description

technical field

[0001] The invention relates to the technical field of environmental protection, in particular to wet flue gas desulfurization equipment, and in particular to a folding plate type gas-liquid diversion device. Background technique

[0002] The "Coal Power Energy Conservation and Emission Reduction Upgrading and Transformation Action Plan (2014-2020)" requires the eastern region (Liaoning, Beijing, Tianjin, Hebei, Shandong, Shanghai, Jiangsu, Zhejiang, Fujian, Guangdong, Hainan and other 11 provinces and cities) to build new coal-fired power plants. The emission concentration of air pollutants from generating units has basically reached the emission limit of gas turbine units (that is, under the condition of a reference oxygen content of 6%, the emission concentrations of soot, sulfur dioxide, and nitrogen oxides are not higher than 10, 35, and 50 mg / m3 respectively). In principle, newly-built units in the region (8 provinces including Heilongjiang, Jilin, Shan...
