[0002] The desulfurization tower is a tower-type equipment for desulfurization of industrial waste gas. The working principle of the desulfurization tower is to cool the water vapor in the flue gas to below the air dew point through the cooling tower, thereby reducing the pollution to the atmospheric environment. In addition, the gas is further cooled and dissolved in water after entering the cooling tower, so it can also effectively prevent the deposition of dust and particulate matter in the waste gas. The main advantages of the desulfurization tower include effectively removing harmful gases such as sulfur dioxide in the flue gas, reducing the emission of atmospheric pollutants, and improving the environmental quality.

[0003] The desulfurization tower is one of the important equipment in industrial waste gas treatment. It has a wide range of applications and various types. After the exhaust pipe of the desulfurization tower is used, dust will adhere to its inner wall. Since the pipe is narrow and long, it is inconvenient to clean it. Therefore, it is necessary to develop a dust removal device for the flue gas desulfurization tower. Utility Model Content

[0031] A dust removal device for a flue gas desulfurization tower comprises a smoke exhaust pipe 100, which is arranged on the desulfurization tower for exhausting smoke, and the gas entering the smoke exhaust pipe 100 is treated gas;

[0032] The inner cavity of the smoke exhaust pipe 100 is provided with a mounting ring 200 through a lifting assembly. Semicircular receiving plates 210 are symmetrically rotated on both sides of the top of the mounting ring 200 through a rotating rod 240 and a mounting strip 250. When the two receiving plates 210 are closed, the smoke exhaust pipe 100 is blocked. An electric lifting and retracting rod 220 is hingedly provided between the bottom of the receiving plate 210 and the inner side wall of the mounting ring 200. The inner side wall of the mounting ring 200 is symmetrically protruded with a mounting block 260.

[0034] The lifting assembly includes mounting seats 400 symmetrically arranged at the upper and lower ends of the front and rear side walls of the inner cavity of the smoke exhaust pipe 100, and a vertical threaded column 410 is rotatably arranged between the two mounting seats 400 on the same side. The rod body of the threaded column 410 is threadedly connected to penetrate the mounting block 1 260 and the mounting block 2 320.

[0035] Furthermore, a dust outlet pipe 110 is provided on one side of the outer wall of the smoke exhaust pipe 100, and the dust outlet pipe 110 is connected to the inner cavity of the smoke exhaust pipe 100. A receiving box is provided on the outside of the smoke exhaust pipe 100 below the outlet of the dust outlet pipe 110. The receiving box is not shown in the figure. The dust outlet pipe 110 can be sealed as a whole in the receiving box. A front door is provided on the front side of the receiving box. Dust enters the receiving box through the dust outlet pipe 110, and the front door is opened for convenient and centralized removal.

[0036] Furthermore, the dust outlet pipe 110 is tilted, and one end of the dust outlet pipe 110 close to the smoke exhaust pipe 100 is higher than the other end away from the smoke exhaust pipe 100. The tilted dust outlet pipe 110 facilitates dust discharge.

[0037] Furthermore, an outer wall of the smoke exhaust pipe 100 is protrudingly provided with a mounting shell 120 on one side relative to the dust outlet pipe 110, and an mounting cavity 130 is provided in the inner cavity of the mounting shell 120. The inner cavity of the mounting cavity 130 is connected to the inner cavity of the smoke exhaust pipe 100, and a horizontal electric push rod 140 is provided inside the mounting cavity 130. A push plate 150 is provided at the output end of the electric push rod 140. The push plate 150 is arc-shaped at one end close to the inner cavity of the smoke exhaust pipe 100. When the receiving plate 210 rises to the height of the lower edge of the push plate 150, the electric push rod 140 is started to push the push plate 150, and the dust accumulated on the receiving plate 210 is pushed into the interior of the dust outlet pipe 110.

[0038] Furthermore, the height of the lower edge of the push plate 150 is the same as the lower edge of the higher end of the dust outlet pipe 110, and the distance between the movable ring 300 and the mounting ring 200 is greater than the height difference between the upper and lower edges of the push plate 150, ensuring that the push plate 150 can penetrate between the mounting ring 200 and the movable ring 300.

[0039] Furthermore, the outer wall of the smoke exhaust pipe 100 is provided with a visual window, which is arranged from top to bottom. The visual window is not shown in the figure, and the height of the lifting and lowering of the receiving plate 210 can be checked through the visual window.

[0040] Furthermore, a notch 270 is provided on the outer side of the receiving plate 210 , and a gap is set between the shaft of the threaded column 410 and the notch 270 , so as to ensure that the receiving plate 210 is not affected by the threaded column 410 when being opened or closed.

[0041] Furthermore, forward and reverse servo motors 420 are arranged at the front and rear of the inner wall of the smoke exhaust pipe 100, and the output end of the forward and reverse servo motor 420 is connected to the end of the threaded column 410. The two forward and reverse servo motors 420 are connected in series. After starting the two forward and reverse servo motors 420, the threaded column 410 is driven to rotate, thereby driving the movable ring 300 to rise and fall.

[0042] During specific use, when the smoke exhaust pipe 100 is exhausting smoke, the electric lifting and retracting rod 220 is started to open the two receiving plates 210, so that the smoke exhaust pipe 100 can exhaust smoke normally. When the inner wall of the smoke exhaust pipe 100 needs to be cleaned, the smoke exhaust is stopped first, the electric lifting and retracting rod 220 is started, the two receiving plates 210 are closed, and then the two forward and reverse servo motors 420 are started to drive the threaded column 410 to rotate, thereby driving the movable ring 300 to rise and fall, and the dust attached to the inner wall of the smoke exhaust pipe 100 is cleaned by the dust scraper ring 310. Most of the dust will fall on the top of the two closed receiving plates 210 below. After cleaning for a period of time, the upper surface of the receiving plate 210 is controlled to move to the height of the lower edge of the push plate 150 through the visual window, and then the electric push rod 140 is started to push the push plate 150, so that most of the dust accumulated on the receiving plate 210 is pushed into the interior of the dust outlet pipe 110, so as to achieve proper cleaning of the interior of the smoke exhaust pipe 100.
