Abstract

The invention discloses a multilayer type carbon fiber pre-oxidizing furnace. The multilayer type carbon fiber pre-oxidizing furnace comprises a furnace body, wherein six to eight layers of independent furnace chambers are arranged inside the furnace body; the furnace chambers are arranged horizontally; an air-passing circulating filtration device is arranged on the left side of the furnace body and is communicated with the furnace chambers; heating tubes are arranged above and below the furnace chambers respectively, and a fan is arranged outside the furnace body. According to the multilayer type carbon fiber pre-oxidizing furnace, the working energy consumption of the fan is reduced, air-passing circulation can be realized, energy is saved, the temperature is uniform by adopting an effective temperature guaranteeing structure, the quality of carbon fibers is benefited, the emission of no waste gas can be ensured by adopting a gas collecting hood, and pollution is greatly reduced.

Description

technical field [0001] The invention relates to a carbon fiber production equipment, in particular to a multi-layer carbon fiber pre-oxidation furnace. Background technique [0002] The pre-oxidation furnace is the key equipment in the production of carbon fiber, and it is also the most energy-consuming equipment in the production of carbon fiber. Its operating temperature is between 200-300°C. It requires uniform temperature in the furnace and hot air circulation to take away the reaction heat of tow. Because waste gas is released during the pre-oxidation process, a waste gas collection and discharge system needs to be installed. Most foreign pre-oxidation furnaces use box-type pre-oxidation furnaces. The blowing methods include side blowing, vertical blowing, and blowing from the middle to both ends. , higher energy consumption. Contents of the invention [0003] In order to solve the problems of harsh operating conditions, large air volume, high fan power, and high en...
