High-efficiency carbon fiber low-temperature carbide furnace waste discharge pipeline system

Abstract

The invention discloses a high-efficiency carbon fiber low-temperature carbide furnace waste discharge pipeline system. The total length of a stainless steel pipeline is 10m or shorter, the internal diameter is 200mm or larger, the wall thickness is 4mm or higher, the number of single side elbow pipes is 4 or smaller; the pipelines on the two ends of each elbow pipe can be cleaned from corresponding cleaning cabins; the high-efficiency carbon fiber low-temperature carbide furnace waste discharge pipeline system is provided with a gauze filter used for collecting broken filament; single side waste discharge port is provided with 2 pipeline flexible couplers or more; all the pipelines and the elbow pipes are provided with flange plates; thermocouples are arranged at the back of the cleaning cabins, and nitrogen introduction equipment is arranged at the front of the cleaning cabins; the number of single side waste discharge port valves is controlled to be 3 or smaller; the pipelines are subjected to different thermal insulation treatment; the temperature of waste gas in the pipelines is controlled to be 300 to 400 DEG C; thermal insulation materials are arranged among the valves, the pipelines, the cleaning cabins, and supports. The high-efficiency carbon fiber low-temperature carbide furnace waste discharge pipeline system is capable of realizing safe and high efficiency cleaning of low temperature carbide furnace waste discharge pipelines by operating personnel as far as possible, and avoiding shutting of carbon fiber production lines because of cleaning of low-temperature carbide furnace waste discharge pipelines effectively, is especially suitable for high efficiency operation of carbon fiber production lines, and is capable of realizing carbon fiber low cost production.

AI Technical Summary

Problems solved by technology

The existing waste discharge pipeline lacks a safe and convenient cleaning cabin, intuitive temperature monitoring and high-safety fire-fighting measures, which not only makes it difficult for operators to clean the low-temperature carbonization furnace waste pipeline safely and efficiently, but also a large number of Tar, and exhaust gas accumulate and condense at the bends in the exhaust pipe system, which will cause blockage of the exhaust pipe after a few days

As the blockage becomes more and more serious, the operation of the carbon fiber production line can only be stopped to clean the waste pipes of the low-temperature carbonization furnace, but this loss is huge
