Description

Technical Field

[0002] High-temperature carbonization is an important process in the production of carbon fiber, and it determines the product quality of carbon fiber to a large extent. During high-temperature carbonization, high-temperature carbonization tail gas will be generated, such as hydrogen cyanide, ammonia, carbon monoxide, carbon dioxide, etc. These gases will pollute the surrounding environment if they are directly discharged into the atmosphere. They need to be transmitted to the exhaust gas treatment system through a negative pressure exhaust pipe for treatment, and the gas will be discharged into the atmosphere after meeting the standards. In the existing technology, after a week of operation, the high-temperature carbonization furnace will clog the exhaust pipe due to the formation of wall hangings by hair and carbon powder, affecting the normal production of carbon fiber. It usually needs to be stopped, disassembled and cleaned, which seriously reduces production efficiency. Utility Model Content
