Experimental Study of Charge Method for Measuring Dust Concentration

ZHAO En-biao,LI De-wen,WANG Zi-liang,YAN Ge-lai,SUI Jin-jun,LI Zhi(Chongqing Branch,China Coal Research Institute,Chongqing 400037,China)  
The aim is to develop a new sensor for measuring the consistence of coal dust via the charge method.Based on the static test theory,the experimental systems are applied to research into the rod-like,inner ring-like,and outer ring-like probe to generate the charge in different consistence of coal dust,and find out the suitable probe for the mine so as to see how different wind velocities and dust particle sizes affect the generated charge for this probe.It is concluded that,for the 3 types of probes,as the consistence of dust increases,more charges are generated,and their relationship is linear;and among the 3 probes,the rod-like probe is the most sensitive and so is more appropriate to measure the consistence of coal dust in the mine.Meanwhile,the experiments have been done to the rod-like probe under different wind velocities and different dust particle sizes.The result shows that,if the wind velocity is different,the linear relationship between the consistence of dust and the generated charge is different;in the scope of 5~7 m/s,the higher wind velocity,the better linear relationship,and the more helpful to accurately measure the consistence of dust;change of particle sizes doesn′t greatly affect the rod-like probe's measuring the consistence of the coal dust.
