摘　　要：分析了煤泥浮选自动控制的特点和关键技术。设计并实现了非接触式的同位素煤浆灰分检测装置及多流分析装置 ,能同时检测原、精、尾煤的灰分。研制了以实时煤浆灰分为反馈量的煤泥浮选优化控制系统 ,用模糊控制方法调节浮选加药量和浮选槽液位 ,在保证精煤质量的前提下提高精煤产率。通过现场实践证明了技术路线的可行性。The key technology of coal slurry floatation automatic control was addressed in this paper. A non-contact isotopic ash measuring device and a multi-slurry analysis device were designed and realized to detect ash contents of raw coal, washed coal and rest coal respectively in flotation process. A coal slurry floatation optimizing control system based on ash on-line measurement was developed, which adopts fuzzy logic algorithm to control the flotation chemicals and liquid level in flotation cells. By using this system, the producing rate of high quality washed coal was increased. The successful application in coal preparation plant illustrates the feasibility of this technology.
