[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Reference Figure 1-4A thermal insulation structure for exhaust gas treatment equipment includes a connecting flange 1 and a ceramic thermal insulation gasket 2. One end of the connecting flange 1 is connected to the ceramic thermal insulation gasket 2. A combustion upper cover 7 is provided on the top of the ceramic thermal insulation gasket 2. A combustion head 4 is embedded in the center of the combustion upper cover 7. An ignition rod interface 3 is provided on one side of the combustion head 4. An observation hole 6 is provided on one side of the ignition rod interface 3. A purge gas interface 5 is provided on one side of the observation hole 6. A ceramic thermal insulation lining 8 is provided inside the ceramic thermal insulation gasket 2.

[0022] In this embodiment, the connecting flange 1 is used to fix and support the entire insulation structure to ensure stability and integrity. The ignition rod interface 3 introduces the exhaust gas to be treated into the equipment, and the observation hole 6 discharges the treated gas. It is embedded in the combustion cover 7 through the ceramic insulation lining 8, so that the exhaust gas cannot contact the combustion cover 7 and isolate the heat source at the same time. A flexible ceramic insulation gasket 2 is placed between the combustion cover 7 and the combustion chamber. After installation, the exhaust gas cannot contact the combustion cover 7 to achieve the purpose of isolating the heat source, so that the sealing ring 9 is in a low-temperature state, extending the service life of the combustion head 4 and the sealing ring 9, and reducing the risk of exhaust gas leakage. The purge gas interface 5 is used to prevent gas leakage or external contamination from entering the component when the equipment is not working. An embedded structure is adopted on the combustion head 4 to reduce the contact between the exhaust gas and the combustion head 4 and the sealing ring 9, while isolating the heat source, which can extend the service life of the combustion head 4 and the sealing ring 9 and reduce the risk of exhaust gas leakage. In actual application, the arrangement and number of the combustion head 4 and the combustion cover 7 can also be changed according to actual needs, and are not specifically limited here.

[0023] Reference Figure 2-Figure 3 A sealing ring 9 is provided at the bottom of the connecting flange 1. A rectangle adapted to the sealing ring 9 is opened at the bottom of the connecting flange 1. The sealing ring 9 is used to prevent gas leakage from the gap between the connecting flange 1 and the components. It can provide an elastic contact surface to adapt to the small gaps and unevenness between the components. The rectangular groove is specially designed for the sealing ring 9 to ensure that it is correctly installed and positioned at the bottom of the connecting flange 1 to ensure the sealing effect.

[0024] Reference Figure 1-Figure 2 The combustion cover 7, ceramic thermal insulation gasket 2 and ceramic thermal insulation lining 8 together constitute the combustion chamber. The integrated design of the combustion cover 7, ceramic thermal insulation gasket 2 and ceramic thermal insulation lining 8 ensures the sealing and thermal insulation of the combustion chamber. The ceramic thermal insulation lining 8 is installed inside the ceramic thermal insulation gasket 2 to further provide thermal insulation protection.

[0025] Reference Figure 2-Figure 4A lining insulation pad 10 is provided on the top of the ceramic insulation lining 8. The lining insulation pad 10 is provided on the bottom outer edge of the combustion cover 7 and fits with the ceramic insulation gasket 2. The lining insulation pad 10 is used to enhance the structural stability of the combustion chamber and provide additional insulation and support. The material of the lining insulation pad 10 is made of ceramic heat-resistant material to improve the overall use effect of the device.

[0026] Reference Figure 2 The combustion head 4 is embedded in the combustion cover 7, and the bottom cross-section of the combustion head 4 is "T"-shaped and is embedded in the combustion cover 7. The "T"-shaped bottom design provides a larger contact area, which helps to enhance the connection stability between the combustion head 4 and the combustion cover 7. The "T"-shaped embedded design helps to form a tight seal, reduce gas leakage, and ensure the efficiency and safety of the combustion process. The embedded installation simplifies the installation process of the combustion head 4, and the installation can be completed by simple insertion and fixation. The combustion cover 7 needs to be designed with a corresponding embedded structure according to the "T"-shaped bottom of the combustion head 4 to ensure the correct fit between the two.

[0027] Working principle: The connecting flange 1 is used to fix and support the entire insulation structure to ensure stability and integrity. The ignition rod interface 3 introduces the exhaust gas to be treated into the equipment, and the observation hole 6 discharges the treated gas. It is embedded in the combustion cover 7 through the ceramic insulation lining 8, so that the exhaust gas cannot contact the combustion cover 7 and isolate the heat source at the same time. A flexible ceramic insulation gasket 2 is placed between the combustion cover 7 and the combustion chamber. After installation, the exhaust gas cannot contact the combustion cover 7 to achieve the purpose of isolating the heat source, so that the sealing ring 9 is in a low-temperature state, which extends the service life of the combustion head 4 and the sealing ring 9 and reduces the risk of exhaust gas leakage. The purge gas interface 5 is used to prevent gas leakage or external pollution when the equipment is not working. The components adopt an embedded structure on the combustion head 4 to reduce the contact between the exhaust gas and the combustion head 4 and the sealing ring 9, and at the same time serve the purpose of isolating the heat source, which can extend the service life of the combustion head 4 and the sealing ring 9 and reduce the risk of exhaust gas leakage. The integrated design of the combustion cover 7, the ceramic thermal insulation gasket 2 and the ceramic thermal insulation lining 8 ensures the sealing and thermal insulation of the combustion chamber. The ceramic thermal insulation lining 8 is installed inside the ceramic thermal insulation gasket 2 to further provide thermal insulation protection. The lining thermal insulation pad 10 is used to enhance the structural stability of the combustion chamber and provide additional thermal insulation and support. The material of the lining thermal insulation pad 10 is made of ceramic heat-resistant material to improve the overall use effect of the device.
