摘　　要：针对煤炭装卸环境中的煤粉尘污染状况，运用喷雾降尘方法，使煤炭装卸环境得以根本的改善。通过在试验台上对液体雾化装置的关键部件——喷嘴的一系列喷雾性能测试，得出了一些具体的结果，这些结果是选用喷嘴和设计喷雾降尘装置的依据。同时，对不同类型的喷嘴的适用场合、装置的最佳耗水量、雾滴参数与粉尘粒径的相互关系等一系列问题作了探讨，并就如何在煤炭装卸环境中实现液体雾化技术的自动控制等问题谈了一些设想。In view of coal dust polluting condition of coal handling environment, this paper utilizes the spraying and dust settling method to improve the coal handling environment thoroughly. Some detailed results are obtained by testing a series of spraying performance of the nozzle——the key parts of the liquid atomization unit. These results form a basis for selecting the nozzle and designing the spraying ang dust settling unit. Meanwhile, a series of problems, such as various types of the nozzles, the optimum water consumption of the unit, and the interrelation between the droplet parameter and the coal dust size,are discussed. Moreover,an assumption is made as to how to accomplish the automatic control of the liquid atomization technology in the coal handling environment
