[0002] The regenerative incineration oxidation furnace, also known as the regenerative oxidation furnace, is a device used to treat waste gas. The waste gas is first heated to a temperature close to the thermal oxidation temperature, and then enters the combustion chamber for thermal oxidation. The temperature of the oxidized gas increases, and the organic matter is basically converted into carbon dioxide and water. The purified gas has a lower temperature and can be discharged after meeting the emission standards.

[0003] At present, traditional regenerative thermal oxidation furnaces usually use natural gas as energy. By burning natural gas, the temperature inside the furnace body is increased to achieve exhaust gas treatment, and combustion-supporting air needs to be introduced into the furnace body to improve the combustion efficiency of the natural gas.

At this time, the locking hook 421 remains engaged with the locking groove 4121 on the connecting column 412, so that the connecting column 412 remains limited in the positioning groove 11 by the locking hook 421. Subsequently, the connecting column 412 is released, so that the driving column 424 moves toward the connecting column 412 under the action of the lifting spring 428. , thereby driving the slide bar 426 to move from the side wall of the limiting section 4232 on the side away from the connecting column 412 to the side wall of the limiting section 4232 on the side close to the connecting column 412, and slide along the side wall of the limiting section 4232 on the side close to the connecting column 412 to the bending point of the limiting section 4232, thereby limiting the slide bar 426 by the bending point of the limiting section 4232, so that the slide bar 426 is stationary in the current position. At this time, the locking hook 421 remains in contact with the locking block 422, and the end of the locking hook 421 away from the mounting plate remains inserted into the locking groove 4121 on the connecting column 412, thereby positioning the locking column in the positioning groove 11.

[0051] Reference Figure 5 and Figure 6When the connecting plate 411 needs to be removed, the connecting column 412 is pressed again, so that the connecting column 412 compresses the buffer spring 415, and the driving column 424 is pushed by the top column 427 to continue to compress the lifting spring 428, thereby driving the sliding rod 426 to move from the bending point of the limiting section 4232 on the side close to the connecting column 412 to the side wall of the limiting section 4232 on the side away from the connecting column 412. At this time, the sliding rod 426 has passed the bending point of the limiting section 4232 on the side away from the connecting column 412, and slides along the side wall of the limiting section 4232 in the direction of the recovery section 4233, thereby driving the locking sleeve 423 to continue to rotate slightly clockwise for a distance, so that the locking sleeve 423 drives the locking hook 421 to gradually separate from the locking block 422. When the slide bar 426 moves to the connection position between the limit section 4232 and the return section 4233, the slide bar 426 cannot move further, thereby making the connecting column 412 unable to move further, and then the connecting column 412 is released, so that the driving column 424 moves in the direction away from the lifting spring 428 under the action of the lifting spring 428, thereby driving the slide bar 426 to move into the return section 4233 and slide along the side wall of the return section 4233 close to the connecting column 412, thereby driving the locking sleeve 423 to continue to rotate clockwise through the slide bar 426, thereby driving the locking hook 421 to separate from the locking block 422, so that the locking hook 421 can restore its elastic deformation, thereby making the locking hook 421 separate from the connecting column 412, thereby releasing the lock of the connecting column 412, making it easy for the connecting column 412 to be pulled out of the positioning groove 11.

[0052] Reference Figure 5 and Figure 7 When the slide bar 426 slides along the side wall of the recovery section 4233 close to the connecting column 412 to the connection position of the recovery section 4233 and the descending section 4231 in the adjacent driving groove, that is, when the slide bar 426 moves to the second connection point, the slide bar 426 passes over the first connection point, so that the connecting column 412 can be locked again in the above manner later, and at this time the slide bar 426 remains stationary, the driving column 424 also moves to the initial position, and pushes the connecting column 412 a distance outside the positioning groove 11 through the top column 427, thereby facilitating the removal of the connecting column 412 from the positioning groove 11.

[0053] Reference Figure 8 The balancing mechanism 3 includes a balancing shell 31 and a balancing joint 32. The balancing shell 31 is detachably mounted on the side wall of the furnace body 1, and the balancing shell 31 covers one end of the silicon carbon rod 211 outside the furnace body 1. The balancing joint 32 is fixedly mounted on the side wall of the balancing shell 31, and one end of the balancing joint 32 is connected to the interior of the balancing shell 31, and the other end of the balancing joint 32 is connected to an external gas source through a pipeline.

[0054] The working principle of the embodiment of the present application is as follows: an external power source supplies power to the silicon carbon rod 211 through a wire 213, so that the part of the silicon carbon rod 211 located in the furnace body 1 generates heat, thereby raising the temperature in the furnace body 1, so as to facilitate the treatment of the waste gas in the oxidation chamber. When the gas inside the furnace body 1 escapes from the gap between the silicon carbon rod 211 and the side wall of the furnace body 1 into the balance shell 31, or a pressure difference is generated between the part of the silicon carbon rod 211 located in the furnace body 1 and the part of the silicon carbon rod 211 located in the balance shell 31, compressed air is filled into the balance shell 31 or the gas in the balance shell 31 is extracted through an external gas source, so that the pressure in the balance shell 31 is kept balanced with the pressure in the furnace body 1, so as to facilitate the treatment of the waste gas.

[0055] When the silicon carbon rod 211 needs to be replaced, the connecting column 412 is pressed so that the locking assembly 42 unlocks the connecting column 412, thereby pulling the connecting column 412 out of the positioning groove 11, and after removing the connecting disk 411, the silicon carbon rod 211 can be replaced. After the silicon carbon rod 211 is replaced, the connecting disk 411 and the connecting column 412 are reinstalled, and the connecting column 412 is locked by the locking assembly 42, thereby completing the replacement of the silicon carbon rod 211.

[0056] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
