2009年第10期 广东化工 第36卷总第198期 www．gdchem．com ·107 化产车间横管初冷器阻力升高的原因及解决措施 李枫，余海涛 (临涣焦化股份有限公司生产技术部，安徽淮北235139) f摘要】针对临涣焦化厂化产车间横管初冷器易堵塞导致的的问题：初冷后煤气温度偏高，体积变大，造成鼓风机输送能力降低；襁冷后煤 气中焦油、萘等杂质含量增多，造成沉积物堵塞后续工段管道和设备等。提出了生产中解决问题的具体措施：加大入炉配台煤粒度、在煤塔上 方加设脱硫废液管道喷洒废液增加配合煤湿度、增加装炉煤的堆密度。遥过采取这些措旄，在不改造横管初冷器结构的条件下，问题就熊得以 有效控制。 【关键词】横管初冷器；阻力升高；解决措施 【中图分类号】T 【文献标识码1A 【文章编号B007．1865(2009)10一0107．01 TheReasonsand MeasuresfortheIncreasedResistanceofthe Solving of CoolertheChemicalProducts PipePrimary Workshop Li Haitao Feng，Yu ofProduction Limited 2351 (Department Technology,LinhuanCoking Corporation，Huaibei39，China) Abslract：Aimatthe ofhorizonml coolerwhichcausedthe blockedinLianhuancoke-ovenchemical problems pipeprimary by easily plant productsworkshop： Afterthe of is thevolumebecome the oftheairbloweris the primarycooling，thetemperaturegas slightlyhigher,and large，anddeliverycapacity reduced；after andother inthe willbe thiswillcausethesedimentblockinthe and primarycooling，thetar,naphthaleneimpuritiesgas increased,and follow-uppipelines then forwardthe measurestosolvethese the sizeof thedesulfurationwaste equipments．Andput specific problems；increaseparticle bland；add liquor briquette pipe toincreasethehumidityofthebriquetteblendby coal．By not thestructureofthehorizontal coolef，thesecanbesolved． change pipeprimary problems measBle Keywords：cr
