　　管道積灰嚴重時，可以采取以下幾種方法進行處理：

　　When there is severe dust accumulation in the pipeline, the following methods can be used for treatment:

　　人工清灰 ：

　　Manual dust cleaning:

　　定期安排人員從清掃孔開始清灰。

　　Regularly arrange personnel to start cleaning the dust from the cleaning hole.

　　設計管道側面的清掃孔，確保無漏風現象。

　　Design cleaning holes on the side of the pipeline to ensure no air leakage.

　　管道聲波清灰 ：

　　Pipeline acoustic cleaning:

　　利用聲波技術清除管道內的積灰。

　　Use sound wave technology to remove dust accumulation inside pipelines.

　　化學清洗法 ：

　　Chemical cleaning method:

　　使用化學清洗劑將管道內的積灰化解并沖刷干凈。

　　Use chemical cleaning agents to dissolve the accumulated dust in the pipeline and flush it clean.

　　高壓水射流法 ：

　　High pressure water jet method:

　　使用高壓水槍或噴嘴對管道內部進行沖擊和切割，將積灰沖刷干凈。

　　Use high-pressure water guns or nozzles to impact and cut the inside of the pipeline, and wash away the accumulated dust.

　　物理化學清洗 ：

　　Physical and chemical cleaning:

　　利用物理化學原理，如吹脫、氣提、汽提等方法分離管道內的積灰。

　　Using physical and chemical principles, such as blowing off, gas stripping, and steam stripping, to separate accumulated ash in pipelines.

　　機械清淤 ：

　　Mechanical dredging:

　　使用挖掘機或推土機等設備直接將檢查井內的污水吸走，進行清淤工作。

　　Use equipment such as excavators or bulldozers to directly suck up the sewage in the inspection well for dredging work.

　　真空吸取 ：

　　Vacuum suction:

　　通過真空吸取技術，把管道內的雜質過濾掉并收集到指定地點。

　　By using vacuum suction technology, impurities inside the pipeline are filtered out and collected at designated locations.

　　降低吹灰時的空氣壓力 ：

　　Reduce the air pressure during soot blowing:

　　減小吹灰時的空氣壓力，以減小磨損和節能。

　　Reduce the air pressure during soot blowing to minimize wear and save energy.

　　選擇合適的清灰方法時，需要考慮管道的尺寸、積灰的硬度、管道內部的空間以及安全因素。每種方法都有其適用場景和局限性，實際操作時可能需要結合多種方法以達到最佳效果。

　　When choosing a suitable cleaning method, it is necessary to consider the size of the pipeline, the hardness of the accumulated dust, the internal space of the pipeline, and safety factors. Each method has its own applicable scenarios and limitations, and in practical operation, it may be necessary to combine multiple methods to achieve the best results.
