风送转盘式生物农药离心雾化喷头的性能
Performance of an air-assisted spinning disc nozzle for biological pesticide
摘要
Abstract
To improve the situation that there is few special equipment for biological pesticide spraying, the air assisted centrifugal atomization device has been designed and manufactured. By changing the structural param-eters (diameter, number of teeth, bevel)and operating parameters (flow rate, rotational speed and wind speed), this research conducted experiments on the particle diameter, biological pesticide activity and efficacy trials. The main findings are as follows: The bigger atomization wheel diameter is the smaller atomized particle size will be;the smaller the angle degree is the greater atomized particle size will be;the larger number of teeth is the smaller atomized particle diameter will be. As a result, the best combinations of disc nozzle structural parameters have been recommended for various environments. Another conclusion is that the wheel diameter, the turntable angle, and number of teeth have little influence on biological pesticide activity, thus meeting the requirement of plant pest prevention and control. The optimal combination of operational parameters are as fol-lows:The flow rate is 40 L·h-1;the speed is 6 000 r·min-1and the wind speed is 5 m·s-1.From the perspective of pesticide efficacy, Plutella xylostella mortality rate is over 90%, which meets the use requirements.关键词
