Respirable dust in coal mine operation space seriously endangers the health of workers. The existing pneumatic spray technology is not effective in reducing and removing respirable dust. To this end,a new supersonic pneumatic atomization technology was developed. The atomization characteristics were studied by experiments and numerical simulation. The transient dust reduction performance of this technology was compared with that of supersonic siphon and internal hybrid pneumatic atomization dust reduction technologies through multi-scale experiments. The results show that the high-speed fine mist domain is formed in the spray field of the new supersonic pneumatic atomization nozzle,and the droplet size and velocity gradually increase with the increase of spray distance. Compared with supersonic siphon and internal mixing pneumatic atomization nozzles,when the pneumatic pressure is 0.3-0.4 MPa and under different water flows,the new nozzles have smaller droplet size,higher droplet movement speed,and higher dust reduction efficiency,which can reach up to 90%. With the increase of pneumatic pressure,the range of high-speed fine mist area formed by the new nozzle increases,and the concentration of micro-mist increases,so that the dust reduction efficiency of small particle size dust increases at different times. When the pneumatic pressure is 0.4 MPa and the water flow rate is 10 L/h,the dust reduction effect of 2.5-10 μm respirable dust is the best.

为解决现有气动喷雾技术对呼吸性粉尘的实际降除效果不佳的问题,研创一种新型超音速气动雾化技术,通过试验和数值模拟方法分析该技术的雾化特性,并通过多尺度试验对比分析该技术与超音速虹吸式、内混式气动雾化降尘技术的瞬态降尘性能。结果表明:新型超音速气动雾化喷嘴喷雾场中形成高速细雾域,随喷射距离的增加,雾滴粒径逐渐增大、雾滴速度逐渐减小;不同水流量时,随着压力的增大,雾滴粒径减小,雾滴运动速度增大,降尘效率逐步提升;与超音速虹吸式和内混式气动雾化喷嘴相比,不同水流量下,当气动压力为0.3~0.4 MPa时,新型喷嘴均具有更小的雾滴粒径和更大的雾滴运动速度,具有更高的降尘效率,最高可达90%。随气动压力的增大,新型喷嘴形成的高速细雾区域范围增大,微雾浓度增加,使不同时刻小粒径粉尘的降尘效率升高;当气动压力为0.4 MPa、水流量为10 L/h时,对2.5~10 μm的呼吸性粉尘降尘效果最佳。
