摘要
为响应国家燃煤电厂节能减排、减污降碳的重大战略需求,本文研发了电除尘器灰斗纳米涂层技术,对5种纳米涂层样品开展全面性能测试,结果显示所有样品热老化性能优良,均无气泡、开裂及变色现象,符合相关标准要求;其中样品c表现尤为优异,热老化后附着力达0级(切割边缘平滑,网格内无脱落),利用AIBEVS1502K三角度光泽度仪在60°角测量,其光泽度达86.2,表面平整度极佳。通过与传统电加热、蒸汽加热技术进行系统性技术经济对比分析,结果表明该纳米涂层技术可显著降低电除尘器低压电耗,具备突出的技术经济优势。该纳米涂层材料在湖南岳阳电厂1000 MW机组电除尘器连续运行半年,实践表明灰斗卸灰顺畅,且相较于电加热技术,低压电耗实现显著降低,验证了其工程应用的可靠性与高效性。
In order to respond to the national energy saving and emission reduction,pollution reduction and carbon reduction of coalfired power plants,nano-coating technology for dust hopper of electric precipitator has been developed,and the comprehensive performance test of five nano-coating samples has been carried out,and the results show that all the samples have excellent thermal aging performance without bubbles,cracks and discolouration,which is in line with the relevant standard requirements;among them,the performance of Sample c is especially excellent,and the adhesion is up to grade 0(smooth cutting edge,no shedding in the grid)after thermal aging.Sample c showed particularly good performance,with adhesion level 0(smooth cutting edges,no peeling off in the grid)after heat aging,and its gloss level 86.2 measured by AIBEVS1502K 3-angle gloss meter at 60°angle,with excellent surface flatness.Through the systematic technical and economic comparative analysis with the traditional electric heating and steam heating technology,the results show that the nano-coating technology can significantly reduce the low-voltage power consumption of the dust collector,and has outstanding technical and economic advantages.The half-year continuous operation of this nanocoating material in the ESP of 1000MWunit of Hunan Yueyang Power Plant has shown that the ash discharge from the ash hopper is smooth,and the low voltage power consumption is significantly reduced compared with the electric heating technology,which verifies the reliability and efficiency of its engineering application.
