发明名称 ASH CONTENT ONLINE MEASUREMENT SYSTEM AND ASH CONTENT ONLINE CONTROL SYSTEM, AND METHOD THEREFOR
摘要 <p>Disclosed are an ash content online measurement system and an ash content online control system, and a method therefor. The ash content online measurement system is used for online measurement of ash content in coal on a coal conveyor belt or on a coal output conveyor belt. The ash content control system is used for controlling ash content of coal output in the coal preparation technique flow line. The ash content online measurement system comprises: a conveyor, a coal sample forming and shaping apparatus, an X-ray ash content online measuring apparatus and a data acquisition and processing controller. The system further comprises an ash content control apparatus on the coal preparation technique flow line, constituting the ash content control system. The data acquisition and processing controller calculates a current ash content value according to an ash content signal measured by the ash content measuring apparatus and an ash content mathematical model, achieving ash content online measurement, and then sends a control signal to a coal preparation control apparatus, according to the difference between the current ash content value and a target ash content value, to reduce the difference, achieving ash content online control. The present invention achieves ash content online measurement and control, thereby increasing the quality of coal preparation and having important connotations for saving energy and lowering emissions of pollutants.</p>
