【摘要】：针对煤矿井下钻孔工作面粉尘难以治理的实际现状,提出了气动孔口除尘器技术,并对气动孔口除尘器的工作原理进行了介绍。设计了孔口除尘器的节能实验方案,在保证压气参数不变的情况下,分别进行了无旋流器无喷淋、无旋流器加喷淋、有旋流器无喷淋和有旋流器加喷淋4种工况的引射性能实验,得出了进口静压、引射风量、引射比、噪声及耗水量随着压气压力的变化情况。除尘实验表明:在压气参数为0.3 MPa的工况下,无旋流器和有旋流器2种结构除尘器的除尘效率分别达到了97.6%和98.5%,均体现了很好的除尘效果。
[Abstract]:In view of the actual situation that dust is difficult to be treated in the underground drilling face of coal mine, this paper puts forward the technology of pneumatic orifice dust collector, and introduces the working principle of pneumatic orifice dust collector. The energy saving experimental scheme of the orifice dust collector is designed. Under the condition that the pressure parameters are not changed, the hydrocyclone without spray and the hydrocyclone with spray are carried out respectively. The experimental results of ejection performance of hydrocyclone without spray and with cyclone plus spray are obtained. The changes of inlet static pressure, ejection air volume, ejection ratio, noise and water consumption with air pressure are obtained. The dust removal experiments show that the dust removal efficiency of the dust collector with no cyclone and cyclone is 97.6% and 98.5% respectively under the condition of 0.3 MPa pressure gas parameter, which shows a good dust removal effect.
