气压水压差恒定条件下气水混合喷雾加湿器的自动控制研究

The Study on Automatic Controlling Spraying Humidifier by Gas-water Mixing under the Condition of Constant Pneumatic and Hydraulic Pressure Difference

针对卷烟生产工艺要求进行自动控制改造,使气水混合喷雾加湿系统始终保持恒定的气压和水压,实现了不分段连续线性调节.实际应用表明,该系统加湿量大,在加湿的同时可降低温度,减少制冷费用和系统维护费用.

For the demand of the cigarette process revam- ping the Automatic Controller, the spraying humidifier system by gas-water mixing reminds constant pneumatic and hydraulic pressure, achieves no piecewise linear adjustment. Practical application shows that the system has a huge humidification and it can humidify and make the temperature drop at the same time, reduce the cost on cooling and refrigeration system maintenance.
