定形机烟气净化与热能回收

采用“热能回收-喷淋洗涤-湿式静电除尘”三级处理工艺对染整定形机进行废热回收与烟气净化,在不同工况条件下对染整定形机废气采样,并采用石油醚萃取和紫外分光光度法进行检测.结果表明,设备对油烟的净化效率达90％以上,废气中油烟浓度低于5 mg/m3.根据废热回收工程实施前后的热工条件,分别对废气减排部分和气/气换热部分的热能利用效果进行详细核算,综合节能效率大于10％.实施废气治理工程,染整企业可在节省燃料和回收油脂方面获得良好的经济收益,在1～2年时间内即可收回全套设备的工程投资.

Exhaust air cleaning and heat recovery of stenter

Industrial application of heat recovery-spraying rinse-wet electrostatic precipitator technology of a stenter in dyeing and finishing plant is carried out.Exhaust samples are collected at different operation conditions and tested with ultra-violet spectrophotometer after extraction with petroleum ether.The results show that the oil concentration is less than 5 mg/m3 and oil removal percentage is 90% in purified air after treatment of the equipment.Energy saving efficiencies of discharge reduction of exhaust...
