Description

Technical Field

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

[0002] Alkali scrubbing towers and gas-liquid separators are typically two closely connected but functionally independent devices. The core function of the alkaline scrubbing tower is to use an alkaline solution to chemically absorb and remove acidic contaminants from the process gas stream. After alkaline scrubbing, the purified gas flows out from the top of the tower, but at this point, the gas contains a large number of alkaline droplets and mist. If this gas is directly sent to the next stage (such as a compressor, dryer, or burner), it will cause serious problems. The core task of the gas-liquid separator is to efficiently and physically separate the liquid droplets entrained in the gas, ensuring that the outlet gas is dry and clean.

[0003] Traditional gas-liquid separators generally adopt a single-layer structure, with packing material inside the tank to achieve gas-liquid separation. Single-layer gas-liquid separators can generally only be customized. Once the tank for placing the packing material is confirmed and the distance between the discharge port and the manhole is confirmed, if the process changes and packing material needs to be added, there may be a problem of excessive packing material leading to overflow. Therefore, there is an urgent need for an improved technology to solve this problem existing in the current technology. Summary of the Invention

[0004] The purpose of this invention is to provide a gas-liquid separator for an alkali washing tower to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas-liquid separator for an alkali washing tower, comprising a lower cylinder, an upper cylinder, a bottom tank, a top cover, a lower support grid, an upper support grid, a lower pressure ring, and an upper pressure ring. The bottom of the lower cylinder is connected to the top of the bottom tank via a flange, the top of the lower cylinder is connected to the bottom of the upper cylinder via a flange, and the top of the upper cylinder is connected to the top cover via a flange. A lower support ring is provided at the connection between the lower cylinder and the bottom tank, and an upper support ring is provided at the connection between the lower cylinder and the upper cylinder. A lower support grid is provided inside the lower cylinder and on the upper surface of the lower support ring, and an upper support grid is provided inside the upper cylinder and on the upper surface of the upper support ring. A discharge hole and a hand hole are provided on one side of both the lower and upper cylinders. The lower pressure ring is movably disposed within the lower cylinder, and the upper pressure ring is movably disposed within the upper cylinder.

[0006] Preferably, the gas-liquid separator for an alkali washing tower provided by this utility model has a drain port at the bottom end of the bottom tank and an air inlet, a viewing window and a spare port on the side wall of the bottom tank.

[0007] Preferably, the gas-liquid separator for an alkali washing tower provided by this utility model includes several support legs connected to the outer wall of the bottom tank.

[0014] Please see Figure 1-2 This utility model provides a technical solution: a gas-liquid separator for an alkali washing tower, comprising a lower cylinder 1, an upper cylinder 2, a bottom tank 3, a top cover 4, a lower support grid 5, an upper support grid 6, a lower pressure ring 7, and an upper pressure ring 8. The bottom of the lower cylinder 1 is connected to the top of the bottom tank 3 via a flange, and the top of the lower cylinder 1 is connected to the bottom of the upper cylinder 2 via a flange. The top of the upper cylinder 2 is connected to the top cover 4 via a flange. The top cover 4 is provided with an exhaust port 18 to discharge the gas after gas-liquid separation. A lower support ring 9 is provided at the connection between the lower cylinder 1 and the bottom tank 3, and an upper support ring 10 is provided at the connection between the lower cylinder 1 and the upper cylinder 2. A lower support grid 5 is provided inside the lower cylinder 1 and on the upper surface of the lower support ring 9, and a lower support grid 5 is provided inside the upper cylinder 2 and on the upper surface of the upper support ring 10. The separator is equipped with an upper support grid 6. Both the lower cylinder 1 and the upper cylinder 2 have discharge holes 11 and hand holes 12 on one side. The lower pressure ring 7 is movably installed inside the lower cylinder 1, and the upper pressure ring 8 is movably installed inside the upper cylinder 2. The lower cylinder 1 and the upper cylinder 2 are filled with packing 19. The packing 19 inside the lower cylinder 1 is supported on the lower support grid 5, and the packing 19 inside the upper cylinder 2 is supported on the upper support grid 6. When gas carrying liquid droplets enters the lower cylinder 1 and the upper cylinder 2 through the packing 19, the flow rate will suddenly decrease. Since the density of the liquid droplets is much greater than that of the gas, and through the adsorption of the packing 19, the larger liquid droplets will naturally settle to the bottom of the separator under the action of gravity. In use, the lower pressure ring 7 and the upper pressure ring 8 press down on the packing 19 inside the lower cylinder 1 and the upper cylinder 2, respectively. The bottom of the bottom tank 3 is provided with a drain port 13 to discharge the separated liquid. The side wall of the bottom tank 3 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 to enter after being washed by the alkali washing tower. The viewing window 15 is used to view the internal condition of the gas-liquid separator. The spare port 16 is used for the temporary discharge of gas after blockage. Several support legs 17 are also connected to the outer wall of the bottom tank 3 to achieve overall lifting, support and fixation.

[0015] Installation method and operating principle: Connect the lower support grid 5 to the inner ring of the lower support ring 9 with bolts. Connect the upper support grid 6 to the inner ring of the upper support ring 10 with bolts. Then, clamp the lower support ring 9 between the flanges of the lower cylinder 1 and the bottom tank 3, and tighten the connection with bolts. Place one of the pressure rings into the lower cylinder 1. Clamp the upper support ring 10 between the flanges of the upper cylinder 2 and the lower cylinder 1, and tighten the connection with bolts. Then, place the other pressure ring into the upper cylinder 2. Finally, install the top cover 4 on the top of the upper cylinder 2 with flanges and bolts to complete the installation. Before use, seal the discharge hole 11 with a blind flange, lift the pressure ring, and add the packing 19 into the lower cylinder 1 and the upper cylinder 2 through the hand hole 12. Then, press the pressure ring onto the packing 19, ready for use. Connect the pipe connected to the outlet of the alkali washing tower to the inlet 14, then connect the exhaust port 18 to the exhaust pipe, and the liquid outlet 13 to the liquid outlet pipe. The spare port 16 is connected to the spare exhaust pipe through a valve to prevent temporary gas discharge in case the packing is blocked. During operation, the gas, which carries a large amount of alkali droplets and mist and has been purified by alkali washing, enters the bottom tank 3 from the inlet 14. Then, it passes through the packing 19 inside the lower cylinder 1, where the gas and liquid undergo preliminary separation. The gas then rises and passes through the packing 19 inside the upper cylinder 2 for secondary gas-liquid separation. Finally, the dry gas is discharged from the exhaust port 18 of the top cover 4. This utility model has a reasonable structure. The bottom of the lower cylinder 1 is provided with a lower support grid 5, and the bottom of the upper cylinder 2 is provided with an upper support grid 6, which can realize the placement of two layers of packing 19, greatly improving the gas-liquid separation effect. In addition, both the lower cylinder 1 and the upper cylinder 2 are provided with discharge holes 11 and hand holes 12, which can replace the packing 19 separately, greatly improving flexibility. At the same time, if the process changes and packing needs to be added, the packing of the lower cylinder 1 does not need to be added, only the upper cylinder 2 needs to be added, further expanding the scope of application and preventing packing overflow.
