Technical Field

[0001] The utility model relates to the technical field of wet desulfurization devices, and particularly relates to a flue anti-blocking detection device. Background Art

[0002] At the inlet position of the flue pipe of the wet desulfurization absorption tower, there is a region where dry and wet meet. Hot flue gas and low-temperature absorption tower spray slurry collide and converge in this region earliest. Dust contained in the flue gas and solid particles such as gypsum carried in the slurry often deposit and solidify, that is, scale, in this region, and then continuously accumulate and thicken on the inner wall of the flue pipe.

[0003] The existing Chinese patent with the authorized announcement number of CN114453355B discloses a wet desulfurization flue anti-blocking device, which includes a flue pipe, a threaded cylinder, a stud, a driving mechanism, a spraying mechanism and a scraper. The threaded cylinder is fixedly connected inside the flue pipe and is coaxially arranged with the flue pipe. The stud is inserted into the threaded cylinder and is threadedly connected with the threaded cylinder. The driving mechanism is connected to the flue pipe and is used to drive the stud to rotate around its own axis. The spraying mechanism is connected to the stud, and the scraper is connected to the spraying mechanism, and the scraper is used to scrape the sundries on the inner wall of the flue pipe. In this application, while the driving mechanism drives the stud to rotate around its own axis, it also moves along the axial direction, increasing the cleaning range of the spraying mechanism and the scraper on the inner wall of the flue pipe, improving the cleaning effect of the inner wall of the flue pipe, reducing the blockage probability of the flue pipe, and improving the blockage situation of the desulfurization flue.
