Description

Technical Field

[0001] This utility model relates to the field of scrubbing towers, specifically an improved structure for delaying ash accumulation in the scrubbing tower of a gasification device. Background Technology

[0002] A gas scrubbing tower is a new type of gas purification equipment. It is an improvement upon the floating packing layer gas purifier and is widely used in pretreatment for industrial waste gas purification and dust removal, achieving excellent purification results. For coal gasification processes, gas scrubbing is unavoidable; this unit operation is used regardless of the coal gasification technology. Because its working principle is similar to a washing process, it is named a gas scrubbing tower.

[0003] Existing scrubbing towers clean the packing material by washing it with water to remove impurities and contaminants adsorbed within the packing. The wastewater then flows along the inner wall of the pipe into a collection tank for recycling. During this process, the wastewater inevitably comes into contact with the pipe wall, causing solid contaminants to accumulate. Furthermore, the accumulated ash cannot be cleaned during operation, reducing efficiency. Therefore, those skilled in the art have provided an improved structure to delay ash accumulation in the scrubbing tower of a gasification unit, addressing the problems mentioned in the background section. Utility Model Content

A cylindrical air inlet section 2 is provided on one side of the top of the circulating water tank 1. A packing section 3 is provided at the top of the air inlet section 2. A packing support plate 19 is bolted to the bottom of the packing section 3. Packing 20 is provided at the top of the packing support plate 19. A water washing section 4 is provided at the top of the water washing section 4. A demisting section 5 is provided at the top of the demisting section 5. A demister 22 is bolted to the inside of the demisting section 5. An air outlet 6 is provided at the top of the demisting section 2. The air inlet section 2, packing section 3, water washing section 4, and demisting section 5 are fixedly connected by flanges. A water collecting cone 13 is bolted to the inside of the air inlet section 2. Multiple air inlet pipes 25 are evenly distributed on the side of the water collecting cone 13. The protruding part of the air inlet pipe 25 is... Inside the water collecting cone 13, a cleaning plate 14 is rotatably connected. A rotating shaft 27 is welded to the center of the cleaning plate 14, and a driven bevel gear 15 is provided at the bottom of the rotating shaft 27. A motor 16 is located at the middle of the inner side of the top of the circulating water tank 1. An active bevel gear 18 is provided at the output end of the motor 16. The active bevel gear 18 meshes with the driven bevel gear 15. A circulating water pump 10 is fixedly connected to the other side of the top of the circulating water tank 1 by bolts. A primary water washing pipe 12 is provided at the top of the circulating water pump 10. The primary water washing pipe 12 leads to the middle of the water washing section 4. A rotating nozzle 21 is threadedly connected to the top of the primary water washing pipe 12. During the water washing process, the rotating cleaning plate 14 scrapes the inner wall of the water collecting cone 13 to prevent the accumulation of dust, effectively slow down the accumulation of dust, and improve the working efficiency of the washing tower.

[0026] The packing support plate 19 has a cavity inside the support beam, and the bottom of the packing support plate 19 has multiple water spray holes 24. The middle part of the primary water washing pipe 12 is connected to the secondary water washing pipe 11 through a tee. The secondary water washing pipe 11 is connected to the cavity of the packing support plate 19. The secondary water washing pipe 11 sprays water onto the water collecting cone 13 through the water spray holes 24 to slow down the ash accumulation rate.

[0027] The bottom center of the filler support plate 19 is welded with a positioning sleeve 23. The positioning sleeve 23 is rotatably connected to the rotating shaft 27 through a bearing, which improves the rotational stability of the cleaning plate 14 and improves the cleaning efficiency of the accumulated ash.

[0028] The cleaning plate 14 has an avoidance groove 28 at the edge corresponding to the position of the air inlet pipe 25. The avoidance groove 28 is slidably connected to the air inlet pipe 25. The cleaning plate 14 has a triangular notch in the middle to prevent the cleaning plate 14 from affecting the efficiency of air intake and drainage when it rotates.

[0029] Among them, a support plate 17 is welded to the center of the inner side of the top of the circulating water tank 1. The support plate is rotatably connected to the output end of the motor 16, which improves the stability of the rotation of the active bevel gear 18, thereby making the rotation of the cleaning plate 14 more stable and improving the cleaning quality.

[0030] Among them, the side of the air inlet section 2 is provided with an air inlet duct 7, and the side of the water washing section 4 is provided with an inspection port 8. The inspection port 8 is fixedly connected to a baffle by bolts for easy maintenance.

[0031] Among them, a circular sealing plate 26 is welded to the bottom of the water collecting cone 13.

[0033] The working principle of this utility model is as follows: The pipe of the gas to be washed is connected to the air inlet pipe 7 by a flange. The gas to be washed enters the air inlet section 2. Under the sealing action of the sealing plate 26, the gas carrying the washing gas enters the water collection cone 13 from the air inlet pipe 25 on the side of the water collection cone 13 and moves upward into the packing layer 20 in the packing section 3. The circulating water pump 10 pressurizes the water in the circulating water tank 1 and sends it into the primary water washing pipe 12 and sprays it out through the rotating nozzle 21 to wash the gas in the packing layer 20. After washing, the gas passes through the demister 22 in the demister section 5 and is discharged from the air outlet 6. The wastewater generated by washing falls into the water collection cone 13 and finally falls from the bottom of the water collection cone 13 into the circulating water tank 1 for recycling. During the process, the motor 16 located in the circulating water tank 1 operates, driving the active bevel gear 18 to mesh with the driven bevel gear 15, causing the rotating shaft 27 to rotate and drive the cleaning plate 14 to rotate. The cleaning plate 14 continuously scrapes the inner wall of the water collection cone 13 to prevent the accumulation of ash. Since the support beam of the packing support plate 19 is provided with a cavity, and the bottom of the packing support plate 19 is provided with multiple water spray holes 24, a secondary water wash pipe 11 is provided in the middle of the primary water wash pipe 12. The secondary water wash pipe 11 is connected to the cavity of the packing support plate 19. The secondary water wash pipe 11 sprays the water collection cone 13 through the water spray holes 24 to slow down the ash accumulation rate, effectively improve the working efficiency of the washing tower, and has a high degree of automation and is easy to use.
