Abstract

The invention relates to a wet flue gas desulfurization gypsum dehydrator, which comprises a host system and a vacuum system, wherein the host system comprises a frame, a slurry tank, a rotating device, a driving device, a discharging device and filter disks; two ends of the slurry tank are fixed on the frame; the rotating device has a cylindrical structure, and two ends of the rotating device are fixed at two ends of the slurry tank; the driving device drives the rotating device to rotate in the slurry tank; a plurality of filter disks are arranged on the rotating device, the filter disks have a shape of an annular disk, each filter disk encircles the outer circumferential surface of the rotating device, cavities are formed in the filter disks, and the surfaces of the filter disks are provided with micropores communicated with the cavities; the discharging device is fixed on the slurry tank and is in contact with the surfaces of the filter disks; and the vacuum system is communicated with the cavities in the filter disks. The wet flue gas desulfurization gypsum dehydrator has the advantages of reliable performance, small floor area, low energy consumption, low switch maintenance cost and good dehydrating effect.

Description

Technical field [0001] The invention relates to a flue gas wet desulfurization gypsum dehydrator, belonging to the field of flue gas wet desulfurization gypsum dehydration. Background technique [0002] Usually, the flue gas of power plant contains sulfur (SO 2 ) It must be removed by a desulfurization device before it is discharged. The flue gas desulfurization generally adopts limestone-gypsum wet flue gas desulfurization (FGD) system. At present, most domestic and even the world adopt limestone-gypsum method for desulfurization (SO 2 ) The thermal power plants of the system all use vacuum belt dehydrators to separate solid-liquid end products. This kind of vacuum belt dehydrator has the advantages of mature technology, reliable performance and simple operation in this industry. But on the other hand, this kind of vacuum belt dehydrator has the disadvantages of large area, high investment, high energy consumption, high filtrate concentration and high maintenance cost.
