Background
Although most of fog drops can be removed after flue gas in the wet flue gas desulfurization system passes through a spraying layer and a demister of the absorption tower, a certain amount of gypsum slurry still exists in clean flue gas. At the moment, in the process that the clean flue gas in a wet saturation state flows through the chimney at the top of the tower, condensation water is generated on the inner wall of the chimney due to temperature reduction, part of the condensation water flows downwards along the wall of the chimney to the inside of the absorption tower, and part of the condensation water is taken out by the flue gas and discharged into the atmosphere, so that a gypsum rain phenomenon is formed around the absorption tower. Whether the phenomenon is slight or serious, the phenomenon of 'gypsum rain' causes pollution to the surrounding environment, and therefore treatment is needed.
At present, the scheme for treating gypsum rain in an absorption tower in a wet flue gas desulfurization system is provided in China, such as: chinese patent (CN203704004U) discloses a wet desulphurization gypsum rain elimination device, which comprises a liquid collecting ring, a liquid collecting tank, a liquid guide pipe and the like, and the device is arranged in two layers, has simple structure and small processing and installation difficulty, but has serious liquid leakage, low efficiency and poor treatment effect; also for example, chinese patent (CN103341274A) discloses a device for recovering moisture from flue gas by wet desulfurization and treating gypsum rain, which mixes air with flue gas by adding a flue, an air inlet, and an enclosing eave, etc. to reduce the temperature of flue gas, so as to reduce and recycle the condensed water in flue gas. Therefore, the efficient treatment of the cream rain is a problem which needs to be solved by the technical staff at the present stage.
