对流室炉管外壁清洗机设计与试验

Design and Experiment of Outer Wall Cleaning Machine for Convection Section

针对加热设备对流室内炉管积灰导致能源浪费和安全隐患等问题,设计了一种可在炉管上实现行走、导向与越障功能的清洗机.该清洗机携带有喷杆,可喷射高压水射流对炉管外壁进行清洗.喷杆可自由调整摆角以实现不同层多根炉管外壁的全面清洗.根据清洗机的结构以及工作流程,设计了清洗机的控制系统.对清洗机进行了动力学仿真,对清洗机设计参数进行了优选.搭建了试验平台与样机,试验结果表明,该清洗机运行平稳,搭载高压水射流后可实现炉管清洗作业.

To solve the problems of energy waste and hidden danger caused by ash in the convection section of chemical equipment,a washing machine was designed with walking,guiding and over obstacle functions on the furnace tube.The washing machine was also designed to carry a spray bar and to be able spray high-pressure water,cleaning the outer wall of the furnace tube.The spray bar was arranged to be freely adjusted to achieve full cleaning the outer wall of multi-furnace tubes in different layers.According to the structure of the washing machine and the work process,a control system was designed for the washing machine.The dynamics simulation of the washing machine was carried out,and the design parameters of the washing machine were optimized.A test platform and the prototype were built.Experiment results show that,the cleaning machine can run smoothly,and the furnace tube cleaning operation can be realized with the installed high-pressure water jet.
