Abstract

The invention discloses flue gas desulfurization equipment. The flue gas desulfurization equipment comprises an absorption tower (10) and a first flue (11) connected to the absorption tower (10). A first induced draft fan (12) of which the outlet faces the absorption tower (10) is arranged on the first flue (11), a first inlet isolation door (13) positioned at the inlet of the first induced draft fan (12), and a first outlet isolation door (14) positioned at the outlet of the first induced draft fan (12) are also arranged on the first flue (11), a first exhaust opening is arranged between the outlet of the first induced draft fan (12) and the first outlet isolation door (14), and the first exhaust opening is connected with a suction device used for sucking flue gas at the outlet of the first induced draft fan (12). The flue gas desulfurization equipment can solve the problem that the induced draft fan cannot be completely isolated, and thus flue gas reversely flees at the outlet.

Description

technical field [0001] The invention relates to flue gas treatment technology, in particular to a flue gas desulfurization equipment. Background technique [0002] With the country's emphasis on environmental protection, all power plants canceled and blocked the desulfurization flue gas bypass, and at the same time canceled the booster fan, and adopted the method of increasing and merging to further reduce the power consumption rate of the power plant. [0003] However, in the design mode of the combination of increasing and drawing, due to the need to overcome the desulfurization resistance, the outlet of the induced draft fan is under a slight positive pressure condition, and the outlet of the induced draft fan adopts a baffle-type isolation door because of the large flue, and the baffle-type The isolation door cannot completely isolate the flue gas. Therefore, in the case of isolation and maintenance of the induced draft fan, there is a problem that the flue gas at the ex...
