摘要:高压静电除尘器是一种具有成熟的技术、简单的结构、维护的费用较低的工业净化烟气的设备，长久以来广泛应用于大气污染治理行业中。静电除尘振打控制系统本身具有时序控制的特点，恰好能够较好的发挥出PLC的优势。所以，电除尘振打PLC控制系统被广泛应用于工业电除尘中。

　　　本文较为详细的概述了可编程控制器PLC在静电除尘器中的应用，设计将以静电除尘器电极振打清灰PLC控制系统的设计作为核心部分，以PLC为核心设计了系统结构图、梯形图、I/O口接线图以及就地操作箱原理图，在电极振打除尘的同时又添加了一些比较的实用的功能，而且简化了电路的结构，使之变得更为灵活且方便控制。

Abstract:High voltage electrostatic precipitator is a purification equipment for industrial flue gas.It has been widely used in the air pollution control industry because of mature technology, simple structure and low maintenance cost. ESP rapping control system has the characteristic of timing control, it can give full play to the advantages of PLC. ESP rapping PLC control system has been widely applied in industrial electrostatic precipitator.

　　　This paper summarizes the application of programmable controller of PLC in electrostatic precipitator. A control system is designed with PLC. The system structure diagram, ladder diagram, I/O diagram and local operation box diagram are designed.

At the same time, some more practical function are added, and the circuit structure is simplified to make the control become more flexible and convenient.
