Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example: See Figure 1-6The present invention discloses a catalytic oxidation device for treating organic waste gas, comprising a reaction chamber 1, a catalytic tube 2 connected to the top surface of the reaction chamber 1, inspection doors 3 evenly arranged on the front end face of the catalytic tube 2, a catalytic component inside the catalytic tube 2, an exhaust fan 4 fixedly installed on the top surface of the catalytic tube 2, a rainproof frame 5 installed on the top surface of the exhaust fan 4, an air intake component on the side of the reaction chamber 1, and an oxidation component on the back of the reaction chamber 1. The modular design facilitates device maintenance and upgrades, and improves practicality.
[0021] In this utility model, the air intake assembly includes a blower 6, one side of which is connected to the reaction chamber 1 via a pipe. The oxidation assembly includes a combustion furnace 7, the front end of which is connected to a burner nozzle 15 via a conduit. The burner nozzle 15 penetrates the reaction chamber 1 and is installed on the reaction chamber 1. The cooperation between the air intake assembly and the oxidation assembly facilitates the combustion of organic waste gas and improves practicality. The catalytic assembly includes a support rail 12, which is horizontally and uniformly fixed inside the catalytic tube 2. A guide rail is fixed to the top surface of the support rail 12, and a guide rail is fitted on the guide rail. A support frame 10 is provided, and a sealing shell 8 is fixedly connected to the back of the support frame 10. A pull handle 9 is fixedly connected to the middle of the back of the sealing shell 8. A sealing ring 11 is inlaid in the middle of the upper and lower surfaces of the sealing shell 8. A support tray 13 is mounted on the top surface of the support frame 10. The support tray 13 has multiple ventilation holes. The support guide rail 12 and the support frame 10 cooperate to facilitate the removal of the support tray 13, which improves practicality. A heat insulation pad 14 is attached to the inner wall of the reaction chamber 1. The reaction chamber 1 and the heat insulation pad 14 cooperate to facilitate the maintenance of the reaction temperature, which also improves practicality.
[0022] Working principle: When using this utility model, first, power is supplied to the electrical equipment, then the organic waste gas is connected, and the gas is connected at the same time. Then, the blower 6 and exhaust fan 4 are started to allow the organic waste gas to enter the reaction chamber 1. Then, the combustion furnace 7 is started, and then the burner 15 is started to spray flames into the reaction chamber 1. After igniting the organic waste gas, the waste gas undergoes an oxidation reaction and becomes inorganic waste gas. Then, because it is high-temperature hot gas, it will rise to the support tray 13. Then, through the catalyst on the support tray 13, the organic waste gas reacts into harmless gas, and then is discharged from the device through the exhaust fan 4. During this process, after the catalyst is consumed, the support frame 10 can be pulled out by holding the handle 9. The support frame 10 slides on the support guide rail 12, allowing the support tray 13 to be pulled out of the catalytic tube 2. Then, a new catalyst is replaced. Finally, the support frame 10 is pushed back into the catalytic tube 2 to complete the catalyst replacement.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
