摘　　要：目的:针对高原地区的特殊地理环境,设计一种适用于高原环境的离心雾化消杀装置。方法:该装置主要由喷雾主体、升降机构与旋转机构、电气控制系统、药箱及车架组成。喷雾主体包括喷雾组件、风机、电动机、风筒等,其中喷雾组件采用多层圆盘叠放的结构形式实现药液雾化;升降机构通过电动推杆实现风筒上下方向调节,旋转机构通过蜗轮蜗杆减速电动机和限位开关实现风筒左右方向调节;电气控制系统主要由电源、用电设备、配电系统和控制系统组成,其中电源为铅酸蓄电池组,控制系统包括DGUS触摸屏和DCS001控制器;药箱由箱体、针阀、水泵、浮球开关等组成;车架由车框架、推手、封板、车轮等组成。试制不同直径的圆盘样件,通过试验对比研究圆盘直径、电动机转速、喷雾流量与雾化效果之间的关系;同时制作样机进行性能测试。结果:试验结果表明,圆盘直径及电动机转速均与雾滴粒径成反比,喷雾流量与雾滴粒径成正比,当喷雾流量增加60%时,雾滴粒径增加范围在2%~11%之间;样机测试结果表明,该装置的雾滴粒径D_(50)和D_(90)分别为31和48μm,可满足高原地区超低容量消杀作业的要求。结论:该装置雾化效果较好,能够满足高原地区防疫消杀的特殊需求。Objective To design a centrifugal agtomization principle-based disinfection and disinsection device for plateau areas.Methods A disinfection and disinsection device was developed based on centrifugal atomization principle,which was composed of a spraying body,lifting and rotating mechanisms,an electrical control system,a spray tank and a sprayer carriage.The spraying body consisted of spraying components,a motor,an air blower,a fan and etc,and the spraying components adopted the structural form of multi-layer disc stacking to realize the atomization of liquid medicine;the lifting mechanism implemented up-and-down adjustment of the air blower through an electric actuartor,and the rotating mechanism executed left-and-right adjustment of the air blower thrgouth the worm gear motor and limit switch;the electrical control system was made up of a power source,electrical devices,a distribution system and a control system,in which a lead-acid battery pack was used for power supply and a DGUS touch screen and a DCS001 controller were involved in the control system;the spray tank was formed of a tank body,a needle valve,a water pump,float switch,etc;the sprayer carriage comprised a frame,a pusher,two sealing plates and four wheels.Some disc samples with different diameters were trial produced,and comparison experiments were carried out to investigate the relationship between disc diameter,motor speed,spray flow rate and atomization effect;a prototype was manufactured for performance testing of the device.Results The disc diameter and motor speed were inversely proportional to the droplet size;the spray flow rate was directly proportional to the droplet size,when the spray flow rate increased by 60%,the increment of the droplet size was restrained within 2%to 11%.The prototype test results indicated that the device could be used for ultra-low-volume disinfection and insecticide in plateau areas,with the D_(50)and D_(90)of the droplet size being 31 and 48μm,respectively.Conclusion The device developed gains advantages in at
