摘要
造纸法薄片生产中烘筒水份控制系统由出口水份、蒸汽压力、入口水份前馈、热风温度和热风速度5个控制回路组成,这些控制回路相互影响,共同控制水份变化。该控制系统应用于生产后,烘筒出口水份的波动范围由设定值的±1.5%提高到了设定值的±1.0%。
In the paper method production of moisture control system consists of outlet water control loop, steam pressure control loop, inlet feedforward moisture control loop, air temperature control loop and air speed control loop, meanwhile, these control loops influence each other and control the moisture change together. After the application of this control system, the exports moisture rang of the drying cylinder is improved from the set value -4- 1.5% to 4- 1.0%.
