[0026] Please see Figures 1-5 This utility model provides a technical solution: an absorption tower for coal gas purification, comprising a base 1 and a body 2, the top surface of the base 1 being fixedly connected to the body 2; an inlet pipe 3 being connected through one side of the body 2 near the bottom, an outlet pipe 4 being connected through the other side of the body 2 near the top, a water outlet pipe 5 being connected through the middle of the bottom surface of the body 2, a water tank 6 being provided on one side of the base 1, a water pump 7 being fixedly installed on the top surface of the water tank 6, an inlet pipe 8 being fixedly connected to one side of the water pump 7, a conveying pipe 9 being fixedly connected to the top surface of the water pump 7, a limiting frame 10 being connected through one side of the conveying pipe 9 near the top, and the limiting frame 10 being fixedly connected to the body 2; further comprising: a plurality of limiting components 11 being provided on the top surface of the water outlet pipe 5; wherein, the limiting component 11 includes a connecting plate 1101 fixedly connected to the water outlet pipe 5; wherein, a connecting box 1102 is fixedly connected to the top surface of the connecting plate 1101, such as Figures 1-5As shown, by setting the limiting component 11, it is easy to replace the screen 20, thereby preventing the screen 20 from clogging and improving the filtration of the sprayed water, thus improving the water recycling effect and reducing water waste. A pull rod 1103 is connected through the inside of the connecting box 1102. A sliding plate 1104 is connected through the surface of the pull rod 1103. A first spring 1105 is fixedly connected to one side of the sliding plate 1104. The side of the first spring 1105 away from the sliding plate 1104 is fixedly connected to the connecting box 1102. The first spring 1105 is sleeved with the pull rod 1103. A locking block 1106 is fixedly connected to the side of the pull rod 1103 away from the sliding plate 1104. Figure 4 , 5 As shown, when installing the screen 20, after inserting the screen 20 into the locking groove 19, the pull rod 1103 is loosened, causing the slide plate 1104 to return to its original position under the action of the first spring 1105. Simultaneously, the pull rod 1103 and the slide plate 1104 are fixedly connected through the spring, allowing the movement of the slide plate 1104 to drive the movement of the pull rod 1103. The movement of the pull rod 1103 then drives the movement of the locking block 1106, thereby causing the locking block 1106 to engage with the locking mechanism. The slots 21 engage to securely limit the screen 20, thereby improving the efficiency of screen replacement and cleaning. The first spring 1105 is a compression spring as used in existing technology. The water outlet pipe 5 has an engagement groove 19 inside, which engages with the screen 20. The screen 20 is connected to the water outlet pipe 5. The screen 20 has symmetrical slots 21 on both sides near the top, which engage with the locking block 1106. Figure 4 , 5 As shown, the engagement of the slot 21 and the block 1106 allows the screen 20 to be positioned and secured, thereby improving the efficiency of replacing and cleaning the screen 20. At the same time, the screen 20 and the water outlet pipe 5 are sealed by a sealing gasket, thereby reducing the occurrence of water leakage.
[0027] A plurality of nozzles 12 are connected through the bottom surface of the delivery pipe 9. A connecting frame 13 is fitted onto the surface of each nozzle 12. A filter screen 14 is fixedly connected to the bottom surface of the connecting frame 13. Limiting rods 15 are connected through the connecting frame 13 near the center on both sides. A second spring 16 is fitted onto the surface of the limiting rod 15. A pull block 17 is fixedly connected to one side of the second spring 16, and the other side of the second spring 16 is fixedly connected to the connecting frame 13. Limiting grooves 18 are symmetrically formed on both sides of the nozzles 12 near the center. The limiting grooves 18 engage with the limiting rods 15. Figure 3As shown, by setting the connecting frame 13 and the filter screen 14, the nozzle 12 can be protected, thereby preventing impurities in the gas from entering the interior of the nozzle 12 and causing damage to the nozzle 12. By setting the limiting rod 15, the second spring 16, the pull block 17 and the limiting groove 18, the connecting frame 13 and the nozzle 12 can be disassembled, so that they can be installed on other nozzles 12, thereby achieving the function of recycling and reducing the increase in cost to a certain extent. Meanwhile, the second spring 16 is a tension spring in the prior art.
[0028] Working principle: Before using this type of gas purification absorption tower, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, when the screen 20 needs cleaning or replacement, pulling the lever 1103 causes the sliding plate 1104 to move. This movement of the sliding plate 1104 compresses the first spring 1105, causing it to deform. Simultaneously, the movement of the lever 1103 also moves the locking block 1106, causing it to separate from the locking groove 21. After separation, pulling the screen 20 separates it from the locking slot 19, facilitating cleaning or replacement of the screen 20. When replacing or installing the screen 20, after inserting the screen 20 into the locking groove 19, the pull rod 1103 is loosened, causing the slide plate 1104 to return to its original position under the action of the first spring 1105. At the same time, the pull rod 1103 and the slide plate 1104 are fixedly connected through the pull rod 1103, so that the movement of the slide plate 1104 can drive the movement of the pull rod 1103. The movement of the pull rod 1103 can drive the movement of the locking block 1106, so that the locking block 1106 is engaged with the locking groove 21, thereby limiting and stabilizing the screen 20, thus improving the efficiency of replacing and cleaning the screen 20.
[0029] Secondly, by setting up the nozzle 12, connecting frame 13, filter screen 14, limiting rod 15, second spring 16, pull block 17, and limiting groove 18, the connecting frame 13 and filter screen 14 can protect the nozzle 12, thereby preventing impurities in the gas from entering the nozzle 12 and causing damage. The limiting rod 15, second spring 16, pull block 17, and limiting groove 18 can also be used to disassemble the connecting frame 13 and the nozzle 12, allowing them to be installed on other nozzles 12, thus achieving recycling and reducing cost increases to some extent.
[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
