The existing flue gas desulfurization technology can be divided into three categories: wet, dry and semi-dry according to the state of the removal agent and the reaction product. The wet process is mature, efficient and widely used.

[0003] Although the new high-efficiency dry desulfurizer device in the prior art has achieved anti-clogging effect, it still has some shortcomings: the desulfurization plate involved in the existing high-efficiency dry desulfurizer device has a simple internal structure, and the flue gas can only pass through the desulfurization plate in the vertical direction, resulting in a short reaction and adsorption contact time between harmful particles in the flue gas and the desulfurizer particles, and a small area, resulting in a deviation in the desulfurization effect. Secondly, the dust removal net involved will have a certain stickiness that will stick to the dust particles after filtering the flue gas for a long time, and the cleaning effect of a single water flushing treatment is deviated. Utility Model Content

[0004] In order to overcome the defects of the prior art, a device for flue gas desulfurization using a composite desulfurizer is now provided to solve the problems of deviation in the desulfurization effect of the desulfurization plate and the cleaning effect on the dust removal net in the existing high-efficiency dry desulfurizer device.

[0014] 2. When the dust net needs to be cleaned, start the drive motor, so that the worm is driven to rotate through the drive shaft, and the meshing transmission of the worm and the worm wheel is used to drive the upper water pipe to rotate, and then drive the cleaning component to rotate.
