Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separator technology, specifically a gas-liquid separator for an acid washing tower that is easy to rinse. Background Technology

[0002] Acid scrubbing towers, also known as acid gas scrubbing towers or wet scrubbing towers, are environmental protection devices that use liquids (usually water or chemical solutions) to contact industrial waste gases, thereby removing acidic pollutants (such as HCl, SO2, H2S, NOx, HF, etc.). After efficient separation and purification in the acid scrubbing tower, the liquid droplets and mists entrained in the gas generally need to be discharged clean and dry through a gas-liquid separator.

[0003] Existing gas-liquid separators used in acid washing towers that are easy to clean allow liquid droplets and mist entrained in the gas to slide directly down the inner wall of the tank after being blocked by the packing. Long-term use may lead to corrosion of the inner wall of the tank, resulting in a reduction in the service life of the tank. Furthermore, cleaning is done manually through the flushing holes, which is inefficient and inconvenient. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Summary of the Invention

An outer folding plate 7 is set at the top of the conical annular plate 4. The outer folding plate 7 is clamped between the flange and the support ring 5 of the tank body 1. An annular water spray pipe 8 is set on the outer surface of the conical annular plate 4. A water pipe joint 9 is set on the side wall of the tank body 1. The water pipe joint 9 passes through the inner wall of the tank body 1 and is set with a bend 10. A connecting pipe 11 is set at the bottom of the annular water spray pipe 8. The connecting pipe 11 is connected to the bend 10. Several nozzles 12 are set on the lower surface of the annular water spray pipe 8. The nozzles 12 face the inner wall of the tank body 1. The tank body 1 is provided with a liquid outlet 13 at the bottom to discharge the liquid droplets after gas-liquid separation. The side wall of the tank body 1 is provided with an air inlet 14, a viewing window 15 and a spare port 16. The air inlet 14 is used for the gas with a large number of liquid droplets and mist discharged from the pickling tower to enter. The viewing window 15 is used for observation. The spare port 16 is connected to a spare pipeline through a valve. When the packing becomes blocked after long-term use, the gas can be temporarily discharged from the spare port. The outer wall of the tank body 1 is connected with several support feet 17 to achieve overall support and fixation. The side wall of the cylinder 2 is provided with a discharge hole 19 and a hand hole 20. The discharge hole 19 is used for discharge when the packing is replaced, and the hand hole 20 is used for adding packing. The cylinder 2 is filled with packing 21. The bottom of the packing 21 is supported on the packing support grid 6. A pressure ring 22 is pressed on the packing 21. The packing 21 is used to contact the liquid droplets and mist in the gas, thereby achieving gas-liquid separation.

[0018] Installation method and operating principle: First, weld the annular water spray pipe 8, which has several nozzles 12 installed at the bottom, to the outer surface of the conical annular plate 4. Pass the water pipe connector 9 through the tank body 1 and weld it. Connect the bend 10 to the inner end of the water pipe connector 9. The outer folding plate 7 of the conical annular plate 4 is supported on the flange of the tank body 1. Connect the annular water spray pipe 8 to the bend 10 through the connecting pipe 11. Support the packing support grid 6 on the upper surface of the support ring 5. Support the support ring 5 on the outer folding plate 7 of the conical annular plate 4 and align the holes. Support the pressure ring 22 on the packing support grid 6. Then, fasten the bottom of the cylinder 2, which has a top cover 3 connected to the top, to the top of the tank body 1 through flanges, bolts, and nuts. At this time, the support ring 5 and the outer folding plate 7 are clamped between the flange of the cylinder 2 and the tank body 1, and the pressure ring 22 is located inside the cylinder 2, completing the installation. Before operation, the air inlet 14 is connected to the air outlet of the pickling tower via a pipe, the water pipe connector 9 is connected to an external water pipe, and the exhaust port 18 is connected to an exhaust pipe. The pressure ring 22 is lifted, and the packing 21 is fed into the cylinder 2 through the hand hole 20. At this time, the discharge hole 19 is blocked by a blind flange, the pressure ring 22 is loosened, and the pressure ring 22 is pressed onto the packing 21. During operation, the gas, which contains a large amount of droplets and mist and has been purified after pickling, enters the tank 1 through the air inlet 14. It then passes through the packing 21 inside the cylinder 2, completing the gas-liquid separation. The gas continues to rise and is discharged from the exhaust port 18, while the potentially acidic liquid drips down the inner wall of the conical annular plate 4. During cleaning, the cleaning fluid enters the annular spray pipe 8 through the water pipe connector 9 and is sprayed onto the inner wall of the tank 1 from each nozzle 12, completing the cleaning of the inner wall of the tank 1. This utility model has a reasonable structure. A support ring 5 and a conical annular plate 4 are provided between the cylinder 2 and the tank 1. The height of the conical annular plate 4 gradually decreases from the outside to the inside. An annular water spray pipe 8 is provided between the outer side of the conical annular plate 4 and the inner wall of the tank 1. Several nozzles 12 are provided at the bottom of the annular water spray pipe 8 facing the inner wall of the tank 1. First, after the gas-liquid separation, the potentially acidic liquid drips down along the conical annular plate 4. At the same time, the inner wall of the tank 1 can be rinsed by the cooperation of the annular water spray pipe 8 and the nozzles 12 on the outer side of the conical annular plate 4. This prevents the potentially acidic mist or droplets from adhering to the inner wall of the tank 1 for a long time, which would cause damage to the inner wall of the tank 1. This greatly improves the overall service life, saves time, improves cleaning efficiency, and reduces labor costs. At the same time, the use of the conical annular plate 4 to install the annular water spray pipe 8 can prevent the liquid separated at the packing 21 from not directly contacting the inner wall of the tank 1, further improving the service life of the inner wall of the tank 1. The conical annular plate 4 is set inside the tank 1 by an outer folding plate 7, which is convenient for disassembly and replacement.
