The outer wall of the reaction tower body 1 is rotatably installed with a sealing door 3 that can seal the replacement port 2. The structure is simple and easy to operate. An integral catalytic plate is divided into several small catalytic plates, thereby facilitating the replacement and installation of the catalyst 13 on the catalytic plate, which is more convenient and labor-saving, improves work efficiency, and reduces labor intensity. The rotating assembly includes an installation box 4 fixed on the inner side of the reaction tower body 1 and located below the installation plate 9. The top of the installation box 4 is rotatably installed with a first rotating shaft 5. The bottom end of the first rotating shaft 5 is located at A worm gear 6 is fixed in the installation box 4, and a second rotating shaft is rotatably installed on the inner wall of the installation box 4. A worm 7 meshing with the worm gear 6 is provided on the outer wall of the second rotating shaft. A rotating wheel 8 is fixed on one end of the second rotating shaft and is located outside the reaction tower body 1. The top of the first rotating shaft 5 is the output end of the rotating assembly. When the second rotating shaft is rotated, the second rotating shaft drives the worm 7 to rotate, the worm 7 drives the worm gear 6 to rotate, the worm gear 6 drives the first rotating shaft 5 to rotate, and the first rotating shaft 5 drives the installation disk 9 to rotate, so that the corresponding first plug-in slot 10 is aligned with the replacement port 2, which is convenient for replacing the catalyst 13; the snap assembly includes a bottom of the installation disk 9 A second plug-in slot 14 is provided on one side of the first plug-in slot, and a plug-in block 15 is slidably installed inside the second plug-in slot 14. A spring 16 is fixed to the top of the plug-in block 15, and the top end of the spring 16 is fixed to the inner wall of the second plug-in slot 14. A card hole 17 is provided through the inner bottom wall of the first plug-in slot 10 corresponding to the plug-in block 15, and the bottom end of the plug-in block 15 is inserted into the card hole 17. The plug-in board 12 is inserted into the first plug-in slot 10. Due to the elastic force of the spring 16, the plug-in block 15 is driven to be inserted into the card hole 17, which facilitates the stable fixing of the plug-in board 12 in the first plug-in slot 10, and the installation is relatively convenient and quick.The disassembly assembly includes a third rotating shaft 20 which is rotatably installed on the inner side of the reaction tower body 1 and is located below the mounting plate 9. One end of the third rotating shaft 20 is fixed with a fixing rod 21, and one end of the fixing rod 21 is rotatably installed with a connecting rod 22.

[0022] The working principle of the utility model is as follows: when in use, the sealing door 3 is opened, the rotating wheel 8 is rotated, the rotating wheel 8 drives the second rotating shaft to rotate, the second rotating shaft drives the worm 7 to rotate, the worm 7 drives the worm gear 6 to rotate, and the worm gear 6 drives the mounting plate 9 on the first rotating shaft 5 to rotate, so that one of the first plug-in slots 10 on the mounting plate 9 is opposite to the rotation replacement port 2, stops rotating, and rotates the handle 23. The handle 23 drives the fixing rod 21 on the third rotating shaft 20 to rotate, and the fixing rod 21 drives the ejector rod 19 to move up and down through the connecting rod 22. The ejector rod 19 ejects the plug-in block 15 from the card hole 17, and then takes out the plug-in board 12 and the catalyst 13, and replaces the new catalyst 13. Then, the plug-in board 12 is inserted into the first plug-in slot 10, and the elastic force of the spring 16 drives the plug-in block 15 to be inserted into the card hole 17 to install and fix the plug-in board 12. The remaining plug-in boards 12 are disassembled and installed according to the above principles and steps.
