# 管路堵料解决方案（中英对照） ## 一、事前预防（优先措施） ### 中文 1. **匹配合理风速** 根据物料特性设定额定气流速度，稀相输送保证风速不低于物料悬浮临界速度；易粘附、比重偏大物料适当提风速，避免低速积料。 2. **管控物料状态** 做好原料防潮、防结块，结块物料提前破碎筛分；杜绝大块异物进入管路。 3. **控制进料量** 均匀定量喂料，避免瞬时进料过载，匹配风机输送能力。 4. **优化管路设计** 减少弯头、变径；弯头选用耐磨大曲率款式，避免直角转向；管路保持顺坡，减少积料死角。 ### English 1. **Set proper air velocity** Set rated air speed according to material properties. Ensure the velocity above the critical suspension speed for dilute phase conveying. Increase speed properly for sticky or heavy materials. 2. **Control material condition** Keep materials dry and prevent agglomeration; crush and screen lumps in advance. Keep foreign objects out of pipelines. 3. **Stabilize feeding rate** Adopt uniform and quantitative feeding to avoid instantaneous overloading, match feeding capacity with fan performance. 4. **Optimize pipeline layout** Minimize elbows and reducers. Use large-curvature wear-resistant elbows instead of right-angle bends. Arrange pipelines with gentle slope to eliminate dead zones. --- ## 二、堵料后现场处理 ### 中文 1. **停机泄压** 立即停止进料、关停风机，待管路内部压力完全释放后再作业，防止喷料伤人。 2. **分段清堵** 从进料端向出料端逐段检查，优先清理弯头、三通、变径等易堵位置；可通过检修口、清堵口人工清料。 3. **气动吹扫** 接入备用压缩空气，反向/正向分段吹扫管路，松散堆积物料。 4. **检查排查** 清堵后查看管路内壁是否磨损、挂料，密封及管件有无异常。 ### English 1. **Stop operation and release pressure** Cut off feeding and shut down the fan. Do not operate until internal pressure is fully released to prevent material ejection. 2. **Sectional blockage removal** Inspect pipeline section by section from feeding end to discharge end. Focus on elbows, tees and reducers. Clean materials manually via access ports. 3. **Pneumatic purging** Connect standby compressed air to blow pipelines forward or reversely in sections to loosen accumulated materials. 4. **Inspect equipment** Check pipeline wall for wear and material buildup, and verify fittings and seals after cleaning. --- ## 三、长期优化与技改 ### 中文 1. **加装监测装置** 在易堵段安装压力传感器、料位报警器，压力异常及时预警。 2. **增设辅助装置** 堵料高发位置加装**气动助吹器、振动器**，定期扰动积料；长管路可配置分段补气装置。 3. **调整系统参数** 反复堵料时，小幅上调风机风量/风压，或降低单位时间进料量。 4. **定期运维** 制定周期巡检计划，清理管路内壁挂料、除尘器积灰，保持系统阻力稳定。 ### English 1. **Install monitoring devices** Mount pressure sensors and level alarms at vulnerable sections for early warning of abnormal pressure. 2. **Add auxiliary equipment** Install air blowers and vibrators at frequent blockage points to shake off deposits. Equip long pipelines with sectional air supplement units. 3. **Adjust system parameters** Slightly increase fan air volume/pressure or reduce feeding rate if blockage recurs frequently. 4. **Regular maintenance** Carry out routine inspection, clean adhered materials inside pipes and dust in collectors to keep stable system resistance.
