[0002] In the sludge carbonization process, organic waste undergoes pyrolysis under high temperature, anaerobic or low oxygen conditions, transforming into carbonaceous products while releasing gaseous and liquid byproducts. This carbonization technology can convert organic waste into efficient fuels or other useful products, while reducing waste volume and harmful gas emissions. A rotary kiln is required in the sludge carbonization process.

The baffle 91 drives the connecting frame 94 to move upward. The connecting frame 94 drives the slide rod 97 to move. The slide rod 97 drives the guide block 98 to slide along the guide rod 99. The guide block 98 will squeeze the spring 991, which can separate the baffle 91 from the cylinder 10, so that the purified flue gas can be discharged, preventing the gas pressure inside the cylinder 10 from being too high and avoiding the emission of flue gas odors that will pollute the environment.
