通过分析现有射流供水压力和喷嘴易堵塞的问题,提出把旋转式雾化器和碰撞理论相结合的雾化降尘技术,开发了一种矿用风水雾化器。分析了雾化器工作时的液滴破碎过程,并将其分成剪切破碎和碰撞破碎两个环节,通过分析液滴破碎机理,提出影响降尘效率和水流损失的原因。通过对不同的供水压力进行了试验研究,验证了雾化器改进的合理性,优化后雾化器的降尘效率提高了约8%。
Based on the analysis of existing water supply pressure and easy plugging of nozzles, the atomization and dust reduction technology combining rotary atomizer and collision theory is proposed, and a mining geo-atomizer is developed. The droplet breaking process of the atomizer is analyzed and divided into two parts: shearing and crushing. By analyzing the droplet crushing mechanism, the reasons that affect the efficiency of dust reduction and water loss are proposed. By experimenting on different water supply pressure, the improvement of the atomizer is verified, and the dust reduction efficiency of the atomizer is optimized by about 8%.
