[0044] In use, the workers will filter the finished exhaust gas through the intake pipe 12 to the catalytic cylinder 11, and react with the catalyst 22 to carry out catalytic combustion (the above-mentioned process of exhaust gas filtration and catalytic combustion is prior art, and the specific structure and process will not be described here), and the burned gas is discharged through the exhaust pipe 13, and then the replacement assembly 2 is used to replace the catalyst 22 to avoid the catalyst 22 from being damaged after long-term use and affecting the subsequent catalytic effect: when the catalyst 22 needs to be removed, the workers pull the push rod 251 outward at the same time, the push rod 251 drives the limiting block 25 to disengage from the limiting hole 26 and retract into the cavity 231, at this time the connecting plate 21 is not limited by the limiting block 25, the workers pull the connecting plate 21 to pull out the connecting plate 21 together with the catalyst 22 from the catalytic cylinder 11, loosen the push rod 251, and then the workers align the new catalyst 22 with the through slot on the catalytic cylinder 11, and push the catalyst 22 into the catalytic cylinder 11, and the catalyst 22 is in contact with the inclined surface of the limiting block 25 on both sides of the connecting plate 21, and the limiting block 25 is extruded into the cavity 231, at this time the spring one 24 is compressed, when the catalyst 22 is completely inserted into the catalytic cylinder 11, the limiting hole 26 and the limiting block 25 are in the same horizontal line, the compressed spring one 24 pushes the limiting block 25 into the limiting hole 26, and the limiting of the connecting plate 21 is completed, at this time the insertion of the catalyst 22 can realize the installation and fixing effect, and the convenience of the operator installation is increased.
