摘要:高壓靜電除塵器是一種具有成熟的技術(shù)、簡(jiǎn)單的結(jié)構(gòu)、維護(hù)的費(fèi)用較低的工業(yè)凈化煙氣的設(shè)備,長(zhǎng)久以來(lái)廣泛應(yīng)用于大氣污染治理行業(yè)中。靜電除塵振打控制系統(tǒng)本身具有時(shí)序控制的特點(diǎn),恰好能夠較好的發(fā)揮出PLC的優(yōu)勢(shì)。所以,電除塵振打PLC控制系統(tǒng)被廣泛應(yīng)用于工業(yè)電除塵中。 本文較為詳細(xì)的概述了可編程控制器PLC在靜電除塵器中的應(yīng)用,設(shè)計(jì)將以靜電除塵器電極振打清灰PLC控制系統(tǒng)的設(shè)計(jì)作為核心部分,以PLC為核心設(shè)計(jì)了系統(tǒng)結(jié)構(gòu)圖、梯形圖、I/O口接線圖以及就地操作箱原理圖,在電極振打除塵的同時(shí)又添加了一些比較的實(shí)用的功能,而且簡(jiǎn)化了電路的結(jié)構(gòu),使之變得更為靈活且方便控制。 關(guān)鍵詞 PLC;靜電除塵;控制系統(tǒng)
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.
