摘要:压力筛是废纸处理过程中的主要设备之一,压力筛控制与废纸制浆质量密切相关。压力筛堵塞是压力筛控制的一个难点,针对以前压力筛堵塞处理的缺陷,提出分3段对压力筛进行控制,分别为比值控制、临界状态的模糊控制和堵塞的顺序控制。运行结果表明,系统可靠性、安全性高,节省资源与资金。 |

Abstract:Pressure screen is one of the main devices in waste paper pulping,it is closely related to the quality of paper pulp.Blocknet is one difficult point for pressure screen,to the fault of blocknet processing,3section control is proposed,which are ration control,fuzzy control in critical state and sequence control for blocknet.Production results show that the system is reliable and safety,saving resource and fund. |
