電熱水鍋爐布袋除塵器的旁路保護(hù)系統(tǒng)是保證除塵器安全的重要設(shè)施，它保證了在熱水鍋爐點(diǎn)火噴油和燃燒異常以及其他熱水鍋爐故障狀況下除塵器的自我保護(hù)，并能通過(guò)控制系統(tǒng)及時(shí)報(bào)警。
1、電熱水鍋爐http://www.hbyuandong.com.cn/除塵器的進(jìn)風(fēng)總管上安裝了溫度檢測(cè)裝置，借助它檢測(cè)到的低于或高于設(shè)定值的煙氣溫度，通過(guò)PLC自動(dòng)打開(kāi)旁路，防止低溫狀況下的結(jié)露堵塞綠高溫?zé)煔鉄龤V袋。
Temperature detection device inlet manifold electric water boiler precipitator installed on, with it detects lower or higher than the set value of the flue gas temperature, automatically opens a bypass through the PLC, to prevent condensation under low temperature conditions blockage green high temperature gas burn bag.
2、電熱水鍋爐點(diǎn)爐時(shí)的投油信號(hào)將進(jìn)入除塵器控制柜中的PLC，在獲得該信號(hào)后，PLC將指揮打開(kāi)旁路閥，使含油煙氣通過(guò)旁路系統(tǒng)排放，保護(hù)濾袋布袋。熱水鍋爐在低負(fù)荷運(yùn)行時(shí)，如果需要投油助燃，由于此時(shí)投油量較小，并且是輕柴油助燃，可以關(guān)閉旁路自動(dòng)系統(tǒng)，借助于管道噴粉裝置投放的粉塵和依靠濾袋表面原有的灰層包裹煙氣中的未燃盡油粒，達(dá)到保護(hù)濾袋的目的。
Electric water boiler cast oil signal point when the furnace into the dust control cabinet PLC, after receiving the signal, PLC will command opens a bypass valve to discharge oily smoke through the bypass system, protecting bag bag. Hot water boiler at low load operation, if needed vote of oil combustion, due to the smaller amount of oil at this time to vote, and is light diesel combustion, you can turn off the automatic bypass system, by means of a pipeline system running dusting dust and rely bag the surface layer of the original parcel flue ash unburned oil particles,the purpose to protect the bag.
3、電熱水鍋爐http://www.hbyuandong.com.cn/如果是少量的爆管，少量的水分對(duì)大量的高溫?zé)煔庥绊懖淮螅瑸V袋表面原有的灰層可以包裹，所以對(duì)熱水鍋爐布袋除塵器沒(méi)有很大的影響。如果是大量的爆管，水量和水壓變化較大，熱水鍋爐系統(tǒng)參數(shù)的陡變，必將導(dǎo)致系統(tǒng)作出相應(yīng)的反應(yīng)并同時(shí)提供給除塵器系統(tǒng)相應(yīng)的信號(hào)，熱水鍋爐也會(huì)按照鍋爐的運(yùn)行規(guī)程采取相關(guān)的保護(hù)措施，將確保熱水鍋爐爆管時(shí)的布袋除塵器的安全。
Electric water boiler if it is a small amount of burst pipes, not a small amount of moisture on a large number of high-temperature flue gas, the original gray bag surface layer can be wrapped, so there is no significant impact on the hot water boiler baghouse. If a large number of burst pipes, water and pressure changes in the larger, hot water boiler system parameters jerk, will cause the system to respond accordingly and also provide a corresponding signal to the filter system, hot water boilers will be in accordance with the boiler operating procedures related to protection measures taken will ensure baghouse hot water boiler tube when safety.
