μXL对盐水过滤器流量的控制

μXL to the Control of Flow of Brine's Filter

在离子膜烧碱生产中,盐水过滤器的流量有特殊要求。不同工况下,流量的大小及变化率不同。针对安全生产过程中的电解电流变化及盐水杂质含量的不同等要求,利用μXL的运算及变化率限制等控制功能,实现对离子膜烧碱系统中的盐水过滤器流量的复杂自动控制。从实际情况看,完全达到了工艺控制要求。

During the production of the IM caustic soda, the brine filter' s flow has special deraands. The rate of flow-ing is not same in the deferent condition. According to the deferent demands of the changeable electric cireuit and impurity of the brine, using the function of μXL' s operation and rate limit accomplishes the complicated automatic control of the flow of brine filter in IM caustic soda system. It meets demands of technology control.
