Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber carbonization furnaces, and in particular to waste gas treatment equipment used in carbon fiber carbonization furnaces. Background Art

[0002] The carbon fiber carbonization furnace is the key core equipment in the carbon fiber production process. Structurally, it has a precisely designed furnace body with a high temperature resistant and stable temperature control heating system inside, which can accurately adjust the temperature range to meet the requirements of different stages of carbonization of carbon fiber. It is usually equipped with advanced temperature sensors and control systems to ensure temperature uniformity and stability, so that the carbon fiber is heated evenly throughout the carbonization process, thereby ensuring the consistency of product quality. At the same time, there is also a special gas circulation and emission system, which can provide the necessary protective gas, such as nitrogen, for the carbonization process on the one hand to prevent carbon fiber oxidation; on the other hand, it can effectively discharge the waste gas generated during the carbonization process to reduce the adverse effects on the environment and products. During the carbonization process, with the removal of impurities in the carbon fiber precursor and the reorganization of the carbon structure, part of the carbon is mixed in the exhaust gas in the form of powder. These carbon powders have a fine particle size, and they move with the airflow under the entrainment of the exhaust gas. From the perspective of the exhaust gas emission system, the presence of carbon powder increases the risk of pipeline blockage, adheres to the inner wall of the pipeline, gradually accumulates, reduces the effective flow area of ​​the pipeline, affects the normal emission of exhaust gas, and may cause abnormal pressure in the furnace.

[0003] If the carbon powder in the exhaust gas of the carbon fiber carbonization furnace is not cleaned up, it will block the pipes and valves. The carbon powder will gradually accumulate in the exhaust gas discharge pipe, making the inner diameter of the pipe smaller and increasing the gas flow resistance. Long-term accumulation may cause pipe blockage and affect the normal discharge of exhaust gas. For valves and other components, the adhesion of carbon powder may hinder their normal opening and closing actions, affect the control function of the entire exhaust gas treatment system, and reduce the operating efficiency of the equipment.
