Technical Field

[0001] The utility model relates to the technical field of screw conveyors, in particular to a kiln desulfurization device of a lime screw conveyor. Background Art

[0002] During the use of the kiln, a large amount of sulfur-containing gas will be generated, so the gas needs to be treated by a desulfurization device. Flue gas desulfurization refers to the process of removing sulfur and compounds in flue gas, mainly SO and SO2 in flue gas, to meet environmental requirements. During the production process of lime water used for desulfurization, the lime slag needs to be filtered and collected, and the lime slag needs to be transported by a screw conveyor.

[0003] Patent announcement number CN111744353A discloses a lime slag filtering device for a kiln desulfurization tower and a desulfurization process using the device, which relates to the field of environmental protection treatment of sewage and waste gas. The scheme includes a lime water circulation pool, a circulating liquid pump and a number of sedimentation boxes. The upper part of the sedimentation box is provided with an overflow port, the bottom of the sedimentation box is provided with a forklift fork claw connection part, and the outside of the sedimentation box is provided with a vibration component that drives the sedimentation box to vibrate. A lime slag filtering device for a kiln desulfurization tower and a desulfurization process using the filtering device are proposed, which can conveniently and quickly precipitate and filter the solid impurity lime slag in the lime water solution, with high filtering efficiency, reducing the labor intensity of workers on the job, and the device has a simple structure and low production cost, with good social and environmental benefits, which is conducive to improving the treatment efficiency of kiln flue gas using filtered lime water, and can reduce material waste, improve resource utilization efficiency, and have good economic and environmental benefits.
