摘要
一种碳纤维旋转垂直式风路超长宽幅预氧化炉的炉箱内设有旋转垂直式风路预氧化结构,该结构包括垂直风循环风路和旋转风分配器,在炉箱内通过竖向隔板分为左箱体和右箱体,左箱体在烟囱效应作用下形成热风上行通道,碳纤维预氧化的炉腔设置在右箱体的中部。旋转风分配器包括上气流分配板和下气流分配板,上气流分配板包括3层密集型孔板,每相邻两层密集型孔板之间各设有一层方孔格栅;下气流分配板为密集型孔板。文章采用上下气流分配、高循环风速设计,碳纤维前进后出;炉腔内的热风和碳纤维垂直设置,碳纤维具有纵横向均温性,内外层快速换热,并具有一定的通用性,降低成本的同时可提高产能效益,提升碳纤维质量。
A carbon fiber rotating vertical air path ultra-long and wide pre-oxidation furnace is provided with a rotating vertical air path pre-oxidation structure in the furnace box.The rotating vertical air path preoxidation structure includes a vertical air circulation air path and a rotating air distributor.The furnace box is divided into a left box and a right box through a vertical partition,and the left box forms a hot air upward passage under the chimney effect.The furnace chamber of carbon fiber pre-oxidation is arranged in the middle of the right box,the rotary air distributor comprises an upper hot air air distribution plate arranged in the upper part of the furnace chamber and a lower hot air air distribution plate arranged in the lower part of the furnace chamber,the upper hot air air distribution plate comprises three layers of dense hole plate,and each adjacent two layers of dense hole plate is provided with a layer of square hole grating;the hot air distribution plate is a dense orifice plate.This paper adopts the design of up and down air distribution and high circulating wind speed,and the carbon fiber is forward and out;the hot air in the furnace cavity and the carbon fiber are vertically set,the carbon fiber has a vertical and horizontal temperature uniformity,the inner and outer layers of rapid heat exchange,and has a certain versatility,reducing the cost and improving the productivity efficiency,improve the quality of carbon fiber.
