[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: a catalytic converter for waste gas treatment, including a shell 1, a catalyst carrier 2 disposed inside the shell 1, and a fixing mechanism 3 installed inside the shell 1. The fixing mechanism 3 includes an installation ring 303, which has multiple holes and a support rod 302 passing through the holes. The other end of the support rod 302 is connected to one side of the fixing ring 301. The outer wall of the support rod 302 has a threaded groove 305, and a nut 304 is threaded into the threaded groove 305. By tightening the nut 304, the installation ring 303 and the fixing ring 301 can quickly install and fix the catalyst carrier 2. The outer wall of the fixing ring 301 is connected to the inner wall of the shell 1, and the outer wall of the installation ring 303 is in contact with and slidably connected to the inner wall of the shell 1. One side of the installation ring 303 is in contact with one side of the catalyst carrier 2, and one side of the fixing ring 301 is in contact with the side of the catalyst carrier 2 away from the installation ring 303.

[0018] In a specific implementation, by setting a fixing mechanism 3, the catalyst carrier 2 is inserted into the housing, allowing the support rod 302 to pass through the catalyst carrier 2. Then, the mounting ring 303 is placed on one side of the catalyst carrier 2, allowing one end of the support rod 302 to pass through the mounting hole of the mounting ring 303. Subsequently, the nut 304 is tightened into the threaded groove 305, fixing the mounting ring 303. This fixes the catalyst carrier 2 with the fixing ring 301 and the mounting ring 303, thus avoiding the need for welding during the installation of the catalyst carrier 2, which would result in low production efficiency. Furthermore, during installation, the catalyst carrier 2 is supported by a support plate 402 inserted into the support groove 404, thereby increasing the strength of the catalyst carrier 2 and preventing deformation that could affect its use.

[0019] One end of the support rod 302 passes through the vent in the catalyst carrier 2, and there is a certain gap between the outer shell 1 and the catalyst carrier 2. An adhesive is provided in the gap. A support mechanism 4 is installed on the inner wall of the fixing ring 301. The support mechanism 4 includes multiple support grooves 404, and the support grooves 404 are opened in the catalyst carrier 2. A support plate 402 is inserted into the support groove 404. An installation strip 403 is connected to one side of the support plate 402. A connecting rod 401 is connected to one side of the installation strip 403. One end of the connecting rod 401 is connected to one side of the inner wall of the fixing ring 301, and one side of the installation strip 403 is in contact with one side of the catalyst carrier 2.

[0020] In a specific implementation, by setting the thickness of the outer shell 1 of the catalyst carrier 2 to be between 0.1 mm and 1 mm, the catalyst carrier 2 can achieve material saving, lightweighting, low back pressure and rapid ignition while maintaining excellent mechanical strength and thermal stability. Furthermore, by forming an α-Al2O3 layer of about 1-2 micrometers thick between the catalyst carrier 2 and the inner wall of the outer shell 1, the adhesion of the coating to the inner wall of the carrier outer shell 1 is increased.

[0021] Working principle: In use, the catalyst carrier 2 is inserted into the outer casing 1, allowing the support rod 302 to pass through the catalyst carrier 2. Then, the mounting ring 303 is placed on one side of the catalyst carrier 2, and the mounting ring 303 is fixed with the nut 304. This fixes the catalyst carrier 2 with the mounting ring 303 and the fixing ring 301, avoiding welding during installation, which would reduce production efficiency. Furthermore, during installation, the catalyst carrier 2 is inserted into the support groove 404 via the support plate 402, which supports the catalyst carrier 2, improving its strength and preventing deformation during use.
