蒸汽锅炉尾气除尘降温节能措施研究

Research on Energy Saving Measures of Dust Removal and Cooling for Steam Boiler Tail Gas

针对储油罐机械清洗作业中使用的移动式蒸汽锅炉尾气除尘降温效果不佳,能源浪费严重的问题,制定了应对措施,并开展了大量现场试验。通过有效扩大换热面积、改变换热方式的方法,在箱体外侧添加利用重力除尘原理的水幕除尘装置,简化氮热一体化冷却装置箱体结构,自制清扫除尘装置,达到了锅炉尾气降温、除尘的预期目的,热能利用率提升了20%以上。

In view of the poor efficiency and serious energy waste of the movable steam boiler used in the mechanical cleaning of the oil storage tank, the countermeasures were formulated and a lot of field experiments were carried out. Through the effective expansion of the heat exchange area and the change of heat transfer process, the water curtain dust removal device using gravity dedusting principle was added in the outer side of the box body, the structure of the nitrogen heat integration cooling device was simplified, and the self- made cleaning and dust removing device was added to achieve the purpose of the boiler exhaust gas cooling and dust removal. Therefore, the heat utilization increased by more than 20%.
