干法除尘蒸发冷却器出口温度控制策略

Control Strategy of Exit Temperature of Evaporative Cooler for Dry Dust Removal

结合蒸发冷却器本身的工艺特点和控制要求,介绍了蒸发冷却器温度控制系统的工艺过程、控制核心算法,给出了一种以串级控制为基础的温度控制策略,解决了系统自动控制中容易出现的超调和频繁振荡的问题。

Based on the process characteristics and control requirements of the evaporative cooler itself, this paper introduces the process and control core algorithm of the evaporative cooler temperature control system, and gives a temperature control strategy based on cascade control to solve the system automatic control. The problem of overshoot and frequent oscillation that is easy to occur is solved.
