Study Of Simulation And Optimization Of Compound Dry Coal Separation Process

China is a country with plentiful coal. The coal energy is one of the pillar industries ofour country. However, most of the abundant coal areas of our country are in the western areaof water shortage. The compound dry coal separation technology becomes a better choicefor the separation of raw coal, as a water-saving, environmental protection, high efficiency,and lower investment process.In order to promote the development of automation of composite dry separation, thispaper mainly explore the correlation about the properties of the raw coal, the equipmentoperating parameters of FGX-1, and the process performance, depends on the equipment ofcompound dry separator of FGX-1which is developed by TangShan ShenZhou machinerygroup to carry on research.Firstly, in order to explore the influence of clean coal segment volume,middlings coal segment volume, waste coal segment volume, the horizontal angle, thelongitudinal angle and vibration frequency to the separation efficiency of the composite dryseparator of FGX-1, this paper test six diffierent coal samples by single factor experiment.Second, we establish the relation model between coal ash and the equipment on the optimalvalues of the parameters when the separation effect is the best of each coal samples.As the separation effect of compound dry separator is largely affected by the coal sizecomposition, we take the+13mm content of40%as the base, the coal is divided into highcontent of coarse and high content of fine grained to disscuss them.Finally, a group of different coal samples tested, prove the credibility of the model.The coal samples whose content of+13mm in raw coal more than40percent:The relationship model of raw coal ash and optimum airflow volume of clean coalsegment: y=-0.0002x2+0.0157x+0.2039The relationship model of raw coal ash and optimum airflow volume of middlingssegment: y=-0.001x2+0.0899x-1.5259The relationship model of raw coal ash and optimum airflow volume of refuse segment:y=0.0008x+0.428The relationship model of raw coal ash and optimum transverse angle:y=-0.0092x+11.906The relationship model of raw coal ash and optimum lengthways angle:y=-0.002x2+0.2142x-5.6457The relationship model of raw coal ash and optimum vibration frequency:y=-0.0139x2+1.0951x+26.479 The coal samples whose content of+13mm in raw coal less than40percent:The relationship model of raw coal ash and optimum airflow volume of clean coalsegment: y=-0.0002x2+0.0157x+0.1639The relationship model of raw coal ash and optimum airflow volume of middlingssegment: y=-0.001x2+0.0899x-1.5459The relationship model of raw coal ash and optimum airflow volume of refuse segment:y=0.0008x+0.363The relationship model of raw coal ash and optimum transverse angle:y=-0.0092x+11.346The relationship model of raw coal ash and optimum lengthways angle: y=1The relationship model of raw coal ash and optimum vibration frequency:y=-0.0139x2+1.0951x+26.829x——raw coal ash/%...
