摘　　要：为解决HDT烘丝机燃烧炉换热管内积碳积垢清洁不彻底而影响换热效率等问题,设计了一种清洁装置。该装置主要由管道内壁清洁单元、导风条清洁单元、空压机和工业吸尘器组成,可以将换热管拆分为管道和导风条后分别进行清理;清理管道内壁的柔性磨头和清理麻花状导风条的柔性滚刷分别由气动马达(额定转速4 500 r/min)和电机(额定转速1 351 r/min)驱动,气动马达由空压机提供压力为0.3 MPa的压缩空气作为气源;清洁后形成的粉尘经密闭除尘管进入工业吸尘器,避免造成扬尘污染。以柳州卷烟厂使用的HDT-FX3000烘丝机为对象进行测试,结果表明:清洁装置应用后,每台烘丝机换热管平均清洁用时由172 min/次减少至63 min/次,降幅63.1%;烘丝过程中天然气消耗量由86.49 m~3/批次下降至82.19 m~3/批次,燃烧炉平均功率降低15.9%。该技术可为提高HDT烘丝机传热效率和减少生产能耗提供支持。In order to remove the ash built up on the inside wall of the heat exchanger tubes in the combustion chamber of HDT tobacco dryer and promote the heat transfer efficiency,a cleaning device was designed.The device mainly consists of a tube cleaning unit,a deflector cleaning unit,an air compressor and an industrial vacuum cleaner.The flexible grinding head for cleaning the tube and the flexible roller brush for cleaning the deflector are driven by an air motor(rated speed of 4500 r/min)and an electric motor(rated speed of 1351 r/min),respectively;and the air motor is driven by compressed air of 0.3 MPa from the air compressor.The removed ash is collected by the industrial vacuum cleaner.The designed cleaning device was tested on the HDT-FX3000 tobacco dryer at Liuzhou Cigarette Factory.The results showed that the average time for cleaning the heat exchanger was reduced from 172 to 63 min,the natural gas consumption for drying a batch of tobacco was reduced from 86.49 m3 to 82.19 m3,and the average power consumption of the combustion chamber was reduced by 15.9%.This device is helpful for promoting the heat transfer efficiency of HDT tobacco dryer and reducing energy consumption in production.
