摘要：

在分析典型木材除湿干燥设备总体结构和工作原理的基础上,设计一种基于模糊控制的智能型除湿干燥控制系统,该系统能够根据干燥窑内实时的温度、相对湿度变化,动态地调节除湿机的开启比例,给出一个控制周期T内最佳的除湿机开启与停止时间,从而精确控制干燥窑内的温度和相对湿度,满足木材干燥基准的要求。生产实际表明,相比于仪表控制方式,本研究设计的控制系统能够在保证干燥质量的前提下,干燥周期由原来的30天减为23天,节能17%左右,同时除湿机的工作时间减少157 h,减轻了设备磨损,延长了设备寿命。

Abstract:

Analyzed with the overall structure and working principle of dehumidification drying equipment, in this study, a kind of intelligent control system was designed on the basis of fuzzy control. The control system could adjust the run-time proportion of dehumidifier dynamically according to the real-time changes of temperature and relative humidity in the drying kiln, then calculated turn-on time and stop time of dehumidifier in one control cycle T, so as to exactly control the drying process to meet the wood drying schedule. Production practice indicated that compared with instrument control, the control system designed in this study could shorten the drying time, from 30 days to 23 days; reduced the energy consumption and the energy-saving ratio is 17% on the premise of good drying quality. At the same time, the running time of dehumidifier decreased by 157 hours, so the device wear was reduced to extend the life of equipment. This study could provide a reference for the design and application of dehumidification drying equipment.

Key words: dehumidification drying for wood, fuzzy optimal control, dehumidifier
