[0038] When the utility model is in use, the acetylene gas generated by the calcium carbide method enters the bottom of the purification tower body 1 through the air inlet 7, and the acetylene gas passes through the placement frame 2. The impurities in the acetylene gas are adsorbed and purified by the filler on the placement frame 2, thereby improving the purity of the acetylene gas to ensure the safety of the acetylene gas in industrial production. When the purification tower body 1 completes the purification of the acetylene gas and needs to replace the filler, the screw rod 304 is rotated by the grip rod 305. When the screw rod 304 rotates, the thread drives the slide rod 303 to slide downward in the slide rod cavity 307, and the guide rod 30 The pair of slide bars 303 play the role of limiting and guiding. The slide bars 303 slide with the guide bars 306. When the slide bars 303 slide downward, the fixed block 301 also moves downward. When the fixed block 301 is no longer engaged with the fixed groove 302 at the bottom of the placement frame 2, the placement frame 2 can be drawn out of the replacement box 14, and the filler on the grid plate 10 is taken out at the same time, and the filler on the placement frame 2 is dumped, and new filler is placed on the placement frame 2 to complete the replacement operation of the filler, thereby improving the efficiency and convenience of replacing the filler. When the placement frame 2 slides outward, The guide rail 401 makes the placement frame 2 slide more smoothly, and the guide wheel 403 will roll with the placement frame 2. When the guide wheel 403 rotates, it drives the rotating shaft 402 to rotate. The sliding friction force is converted into rolling friction force through the guide wheel 403, making the placement frame 2 more stable to be drawn out. When it is necessary to open the inspection door 602 to inspect and maintain the interior of the purification tower 1, the pull plate 607 can be pressed downward. When the pull plate 607 moves downward, it drives the connecting rod 605 to move downward, and at the same time drives the connecting column 603 to move downward. When the connecting column 603 moves downward, it drives multiple expansion blocks 60 4 slides downward, the spring 606 contracts, and when the expansion block 604 is no longer engaged with the connecting shaft 601, the connecting shaft 601 rotates to drive the inspection door 602 to rotate and open. When the inspection door 602 rotates to a certain angle, the pull plate 607 is released, the spring 606 recovers, and drives the connecting column 603 to engage with the connecting shaft 601 again. The connecting column 603, the expansion block 607 and the connecting shaft 601 are engaged to fix the inspection door 602, so as to prevent the inspection door 602 from rotating freely when the operator is inspecting and maintaining the inside of the purification tower body 1.
