Abstract

The invention discloses a hot air circulating pre-oxidation furnace, comprising a front rack, a rear rack, a furnace body, a mesh belt chain transmission mechanism, an exhaust system, a nitrogen atmosphere system and a plurality of heating regions arranged in the furnace body, wherein each heating region is provided with an independent hot air circulating system; the hot air circulating system comprises a circulating fan, an air heater, an internal circulating air duct and an air filter; the air heater is arranged at an air inlet of the internal circulating air duct; the air filter is arranged at an air outlet of the internal circulating air duct; and the circulating fan is connected with the air inlet and the air outlet of the internal circulating air duct. Through the hot air circulating pre-oxidation furnace, the technical problems of high heating energy consumption and high operation cost of the traditional pre-oxidation equipment are solved.

Description

technical field [0001] The invention relates to the field of carbon fiber production equipment, in particular to a hot air circulation type pre-oxidation furnace. Background technique [0002] In the entire process of preparing high-performance carbon fibers, the pre-oxidation process is a very important and key step. As a device for the pre-oxidation process, the pre-oxidation equipment is the basis of the entire carbon fiber preparation process. In the entire carbon fiber preparation process, the pre-oxidation time is the longest, how to improve the processing efficiency of this section of the process, how to improve the processing efficiency of this section of the entire carbon fiber process, has a crucial role in the production efficiency of the entire carbon fiber preparation production Efficiency plays a vital role. Traditional hot air circulation pre-oxidation furnace, a 7.2mx2m (length x width) heating zone, generally speaking, at least 4 fans and 4 air heaters are ...
