Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization devices, in particular to a self-unloading and flushing desulfurization inlet gypsum cleaning device. Background Technique

[0002] Desulfurization refers to fixing the sulfur element in coal into a solid with methods such as calcium-based to prevent sulfur dioxide from being generated during combustion. The limestone-gypsum desulfurization process is one of the most widely used desulfurization technologies in the world. Its working principle is: making limestone powder into slurry with water as the absorbent and pumping it into the absorption tower to fully contact and mix with the flue gas. Sulfur dioxide in the flue gas reacts with calcium carbonate in the slurry and the air blown in from the lower part of the tower to generate calcium sulfate. After calcium sulfate reaches a certain saturation, it crystallizes to form dihydrate gypsum. The desulfurized flue gas passes through a demister to remove droplets, and then after being heated and raised in temperature by a heat exchanger, it is discharged into the atmosphere through a chimney.

[0003] When some crystals are formed during the reaction between the flue gas and lime water to generate calcium carbonate and the like, some crystals will fall to the pipeline through the inlet, resulting in the problem of gypsum material accumulation. The accumulated gypsum material will not only block the desulfurization tower inlet, but also be very difficult to clean. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0015] Referring to Figures 1-3 As shown, a self-unloading and flushing desulfurization inlet gypsum cleaning device includes a base 1. A reaction tank 2 is fixedly connected to the upper surface of the base 1. An inlet 3 is provided on the side surface of the reaction tank 2. An outlet 4 is provided at the upper end of the reaction tank 2. Smoke enters through the inlet 3 and is discharged through the outlet 4. A pipe 8 is fixedly connected to the outer edge of the inlet 3. The inner pipe orifice of the pipe 8 corresponds to the inlet 3. A connecting pipe 7 is fixedly connected to the side surface of the reaction tank 2. The connecting pipe 7 and the pipe 8 are located on opposite sides of the annular surface of the reaction tank 2. The upper end of the connecting pipe 7 is fixedly connected to a first integrated pipe 5. A plurality of nozzles 6 are fixedly connected to the lower surface of the first integrated pipe 5. The first integrated pipe 5 is located above the pipe 8. The lime water is sprayed through the nozzles 6 through the connecting pipe 7, so that the smoke and the lime water undergo a chemical reaction, thereby removing the harmful substances in the waste gas.

[0016] One end of the lower surface of the pipeline 8 away from the inlet is fixedly connected with a cylinder 9. The output end of the cylinder 9 penetrates and is slidably connected to the lower surface of the pipeline 8. The output end of the cylinder 9 is fixedly connected with a joint 11. A short shaft 12 is fixedly connected inside the joint. Both ends of the short shaft 12 penetrate and are rotatably connected to both side walls of a U-shaped plate 13. An aggregate plate 14 is fixedly connected to the upper surface of the U-shaped plate 13. Both side walls of the pipeline 8 near the inlet 3 penetrate and are fixedly connected with a long shaft 16. A connecting block 15 is rotatably connected to the long shaft 16. The upper surface of the connecting block 15 is fixedly connected to the lower surface of the aggregate plate 14. When the output end of the cylinder 9 moves up and down, the joint drives one end of the aggregate plate 14 to move upward. Since the other end of the integrated plate 14 is rotatably connected to both side walls of the pipeline 8, when the cylinder 9 moves, the integrated plate 14 will rotate around the long shaft 16, thereby pouring out the accumulated material. A second integrated pipe 17 is fixedly connected inside the pipeline 8. A plurality of high-pressure spray nozzles 18 are fixedly connected to the lower surface of the second integrated pipe 17. One end of a joint 10 penetrates and is fixedly connected to the side surface of the pipeline 8. The other end of the joint 10 is fixedly connected to the input end of the second integrated pipe 17. The second integrated pipe 17 is located above the interior of the pipeline 8. It flushes the integrated plate 14 with the water sprayed out by the high-pressure spray nozzles 18. By setting the rotating aggregate plate device, the gypsum reactants accumulated at the inlet can be overturned and self-unloaded, and the accumulated gypsum reactants are flushed with the high-pressure spray nozzles above, preventing the blockage problem caused by accumulation.

[0017] When there is too much accumulated material on the integrated plate 14 in the present utility model, the cylinder 9 will be started. When the output end of the cylinder 9 moves up and down, the joint drives one end of the aggregate plate 14 to move upward. Since the other end of the integrated plate 14 is rotatably connected to both side walls of the pipeline 8, when the cylinder 9 moves, the integrated plate 14 will rotate around the long shaft 16, thereby pouring out the accumulated material. At the same time, water is injected into the second integrated pipe 17 through the joint 10, and then the water is sprayed out through the high-pressure spray nozzles, so that the water sprayed out by the high-pressure spray nozzles 18 flushes the integrated plate 14. By setting the rotating aggregate plate device, the gypsum reactants accumulated at the inlet can be overturned and self-unloaded, and the accumulated gypsum reactants are flushed with the high-pressure spray nozzles above, preventing the blockage problem caused by accumulation.
