电热水锅炉布袋除尘器的旁路保护系统是保证除尘器安全的重要设施，它保证了在热水锅炉点火喷油和燃烧异常以及其他热水锅炉故障状况下除尘器的自我保护，并能通过控制系统及时报警。
1、电热水锅炉http://www.jnshengxin.cn/除尘器的进风总管上安装了温度检测装置，借助它检测到的低于或高于设定值的烟气温度，通过PLC自动打开旁路，防止低温状况下的结露堵塞绿高温烟气烧毁滤袋。
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、电热水锅炉点炉时的投油信号将进入除尘器控制柜中的PLC，在获得该信号后，PLC将指挥打开旁路阀，使含油烟气通过旁路系统排放，保护滤袋布袋。热水锅炉在低负荷运行时，如果需要投油助燃，由于此时投油量较小，并且是轻柴油助燃，可以关闭旁路自动系统，借助于管道喷粉装置投放的粉尘和依靠滤袋表面原有的灰层包裹烟气中的未燃尽油粒，达到保护滤袋的目的。
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、电热水锅炉http://www.jnshengxin.cn/如果是少量的爆管，少量的水分对大量的高温烟气影响不大，滤袋表面原有的灰层可以包裹，所以对热水锅炉布袋除尘器没有很大的影响。如果是大量的爆管，水量和水压变化较大，热水锅炉系统参数的陡变，必将导致系统作出相应的反应并同时提供给除尘器系统相应的信号，热水锅炉也会按照锅炉的运行规程采取相关的保护措施，将确保热水锅炉爆管时的布袋除尘器的安全。
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.
