温室药液汽化装置效果研究

Effect of Greenhouse Liquid Gasification Equipment

针对我国温室内农药喷施装置落后、农药利用率较低以及现有的离心式汽化装置汽化效果差、汽化率低等问题,利用伯努利原理,设计出新型农药汽化装置。通过对各喷头和喷头不同安装位置进行对比试验,得出喷头2号和喷头3号为汽化效果良好的汽化装置,1号位置是汽化效果明显的喷头安装位置。通过控制喷口位置和输液管道流量,对新设计的农药汽化装置进行试验,从而得出喷口位置、药液流速等因素对汽化装置的汽化效果影响较大。

In view of the relative backwardness of pesticide spraying equipment in greenhouse,the low utilization rate of pesticides and the poor gasification effect and low gasification rate of pesticide gasification equipment in our country,a new type of pesticide gasification device was designed by using Bernoulli equation.The nozzle 2 and nozzle 3 were the vaporizing devices with good vaporizing by comparing the different nozzle,and the installation position of NO.1 was the insallation position of the nozzle with obvious vaporizing effect by comparing the installation position experiment.Through controlling nozzle position and flow rate of fluid pipeline,the newly designed pesticide vaporization device was experimented to find that effect of nozzle position and liquid flow rate on the vaporization was obvious.
