Abstract

The invention discloses a boiler wet desulphurization and demisting, smoke reheating and chimney corrosion prevention integrated device. The device comprises a boiler (1), a dust remover (2), a suction fan (3), a desulfurizing tower (5), a demisting and dehumidifying device (6) and a chimney (7). The device further comprises a split heat pipe exchanger (4), wherein the split heat pipe exchanger (4) comprises an upper heat exchange tube and a lower heat exchange tube. The boiler (1) is connected with the dust remover (2). The dust remover (2) is connected with the suction fan (3). The suction fan (3) is connected with the lower heat exchange tube. The lower heat exchange tube is connected with the desulfurizing tower (5). The desulfurizing tower (5) is connected with the demisting and dehumidifying device (6). The demisting and dehumidifying device (6) is connected with the chimney (7). The upper heat exchange tube is connected with a pipeline, connected with the demisting and dehumidifying device (6), in front of the chimney (7) through a pipeline. The boiler wet desulphurization and demisting, smoke reheating and chimney corrosion prevention integrated device reduces equipment investment, is low in operation energy consumption, reliable and low in failure rate, and prolongs the unit maintenance cycle.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization, in particular to a boiler wet desulfurization and demisting flue gas reheating chimney anticorrosion integrated device and method. Background technique [0002] With the wide application of wet desulfurization of boiler flue gas, the water content of flue gas after desulfurization has increased significantly compared with that before desulfurization, and the temperature of flue gas is lower than the dew point temperature. It is inevitable that such flue gas will be directly discharged into the original chimney without treatment Cause serious corrosion and form a huge safety hazard. [0003] In order to solve the problem of chimney anticorrosion, two methods are usually adopted. First, the clean flue gas is reheated by using the flue gas heat exchanger GGH (generally a rotary type), and the dry flue gas is kept in the chimney for anticorrosion, but the GGH has the problems of blo...
