RAC2.3-200-460-A01-W1電除塵器低壓控制系統(tǒng)的軟件設(shè)計(jì)
3.1振打控制設(shè)計(jì)
根據(jù)多年對(duì)電除塵器低壓控制系統(tǒng)的運(yùn)行經(jīng)驗(yàn)，為提高電除塵器的除塵效率，有效降低功耗，對(duì)本地振打電機(jī)的優(yōu)化控制作如下要求：
RAC2.3-200-460-A01-W1同一電場(chǎng)中陰極和陽(yáng)極振打不能同時(shí)進(jìn)行；
多電場(chǎng)除塵器中，前后電場(chǎng)陽(yáng)極(或陰極)振打不能同時(shí)進(jìn)行；
設(shè)置有振打槽板的電除塵器，其末電場(chǎng)陽(yáng)極振打和槽板振打不能同時(shí)進(jìn)行。
3.2加熱工作
RAC2.3-200-460-A01-W1加熱器采用恒溫區(qū)間控制，即以設(shè)定溫度的上、下振幅為工作區(qū)間來控制加熱器的啟停。當(dāng)測(cè)量溫度低于設(shè)定溫度低于設(shè)定溫度的下偏差時(shí)，加熱器開始工作，當(dāng)加熱到測(cè)量溫度高于設(shè)定溫度的上偏差時(shí)，加熱器停止工作，直到測(cè)量溫度低于設(shè)定溫度的下偏差，加熱器再次開始加熱，循環(huán)往復(fù)，完成溫度控制。
3.3卸灰控制設(shè)計(jì)
RAC2.3-200-460-A01-W1電除塵器的卸灰方式可分為定時(shí)自動(dòng)卸灰，上、下料位自動(dòng)卸灰及上料位定時(shí)自動(dòng)卸灰。在本系統(tǒng)中采用的是“高料位+時(shí)序”的控制方法，即高料位定時(shí)卸灰，周期卸灰相結(jié)合的綜合方式。所謂高料位卸灰指的是當(dāng)?shù)蛪嚎刂葡到y(tǒng)檢測(cè)到某一上料位信號(hào)時(shí)先啟動(dòng)相應(yīng)的卸灰裝置；當(dāng)器工作一定時(shí)間后，再延時(shí)一段時(shí)間停止相應(yīng)的輸灰聯(lián)鎖系統(tǒng)。為避免出現(xiàn)料位計(jì)損壞或者誤報(bào)而導(dǎo)致電場(chǎng)堵灰，又加入定時(shí)周期卸灰功能，以保證系統(tǒng)能夠進(jìn)行自動(dòng)卸灰。
