摘要
在日光温室里搭载的二氧化碳智能释放系统中,针对研制的管送式温室药物气化装置,通过改变药物喷头、管道位置等因素试验研究了其气化效果,研究结论为:(1)安装喷头的管道处于竖直位置时气化效果较好;(2)管道中心轴线上的气流大小和方向稳定,喷头出液口处于此位置气化效果较好;(3)药液袋和喷头间的水位差与药液气化时间成反比;(4)环境温度与药液气化时间成反比;(5)开关位置与药液流速成正比。
Carbon dioxide intelligent emission system in solar greenhouse, experimental study on gasification effect of nozzle was carried out.The main experimental conclusions were as follows:(1) the vertical placement effect of the pipe installed with spray nozzle was better;(2) the air flow on the central axis of the pipeline was stable and the nozzle outlet should be placed there;(3) the water level difference between the liquid bag and the spray head was proportional to the gasification time;(4) the environmental temperature was directly proportional to the gasification time of the liquid;(5) the switch position was negatively proportional to the liquid flow rate.
