摘要
在烧结法生产氧化铝的生产过程中,最重要的工艺是熟料的煅烧,它在回转窑中进行。在生产过程中能否优质、高产、低消耗地生产熟料和安全运转的关键因素是窑衬。窑衬在生产过程中处于脱落再生平衡状态,形状随时变化。但在旋转的窑里,窑皮形状无法用肉眼观察和直接测绘,给操作带来很大盲目性。为了解决这一难题,采用红外线测温和全数字滤波补偿技术,测量出筒体表面温度及其变化,仿真出窑皮的状况。该技术有效的改善窑的操作,提高设备运转率3％,年综合经济效益486万元,经济效益显著。
In the process of producing alumina by sintering, the most important technic is the calcination of aluminum. The rotational kiln is the core equipment of this process. The key factor in the producing process by rotational kiln is the coat of it, which determine whether the high quality, high yield, low consumption, and safe operation can be realized. In the process the stove's coat is in the balance of desquamating and regeneration, the shape of coat is change every time. But in the rotating kiln, the shape of kiln coat can not be observed with naked eye, and it can not be mapping directly. This makes the operation of kiln become blindness. To solve the problem, the technique of infrared ray scanning and the technique of digital filter and repair was used to measure the stove body temperature, so can emulate the shape of kiln coat. This production improves the operation of rotational kiln, increase the rate of equipment running 3% . The annual economic benefit of it is 4 860 thousand Yuan RMB. It is introduced in this thesis that how the infrared ray scanning is used in the monitoring of the rotational kiln body and liner, and the effect and spread value in practical running.
