Abstract : through analysis of the components of coking on different parts of desullfur system of single tower and the waste water containing sulfur , we find the cause of coking in the stripping desulur system from single tower is the polymerization reaction of carbohydrate and the separattion of varied solid powders , organic compounds , and all corrosive productions of metal out of waste water in high temperature , therefore , the solving method is how to decrease the oil content , how to depolymerize form the carbohydrate and how to antisepticize by vapour of waste water 文摘:对单塔脱硫系统中不同部位的垢物及现场催化含硫污水进行了分析测定,结果表明:塔内污垢成分及含量随塔体部位的不同而不尽相同,单塔汽提脱硫系统中垢物的形成,主要是由于污水中所含各类粉尘、有机物、金属腐蚀物等在高温下因石油碳氢化合物的析出及其单体的聚合反应所致.如何降低污水中的含油成分、减少聚合反应的生成、防止污水蒸气对塔体材料的腐蚀,是阻垢、除垢和防垢应解决的关键问题
