摘要
火电厂超低排放改造要求电除尘系统在高负荷与高频变工况下长期稳定运行,技术瓶颈集中于本体结构适应性与故障干预策略构建。分析了火电厂超低排放改造后电除尘本体故障的典型表现,研究了极板结构变形、粉尘沉积堵塞、电源输出波动与烟气流场偏移的耦合机制,提出了加固应力构架系统、疏通灰渣运行通道、校稳电压干扰模块与重建气体流动结构的系统治理思路,旨在建立结构、电源与气场协同修复的工程化响应路径。
The ultra-low emission transformation of thermal power plants requires the electrostatic precipitator system to operate stably for a long time under high load and high-frequency variable working conditions,and the technical bottleneck is focused on the adaptability of the body structure and the construction of fault intervention strategies.The typical manifestations of faults are analyzed in the electrostatic precipitator body after the ultra-low emission transformation of thermal power plants,the coupling mechanism of plate structure deformation,dust deposition blockage,power output fluctuation,and flue gas flow field deviation is studied,and the system governance idea of reinforcing the stress framework system,dredging the ash operation channel,stabilizing the voltage interference module,and reconstructing the gas flow structure is proposed,aiming to establish an engineering response path for the coordinated restoration of structure,power supply,and gas field.
