Dry process gas dust removal process or the addition of wet electrostatic precipitator process can meet the emission requirements. If the original dust removal system is transformed into a dry process, it covers a large area, has a high investment and a long construction period. Adding a wet electrostatic precipitator in the original system can benefit the old original equipment and the transformation investment is the lowest.展开更多
为了改善生物基锦纶56(PA56)静电严重,可纺性差的缺陷,对PA56短纤维进行抗静电处理并优化梳理工艺。采用手持式静电仪监测了纤维在梳理过程中纤维喂入处、出口处和成卷处的静电势变化,以探究PA56短纤维梳理工艺参数与梳理效果的关系。...为了改善生物基锦纶56(PA56)静电严重,可纺性差的缺陷,对PA56短纤维进行抗静电处理并优化梳理工艺。采用手持式静电仪监测了纤维在梳理过程中纤维喂入处、出口处和成卷处的静电势变化,以探究PA56短纤维梳理工艺参数与梳理效果的关系。结果表明:手持式静电仪可以准确测量纤维表面静电荷,未处理的PA56短纤产生的静电荷多,静电势大,达到+21.2 k V,此时纤维网搭接不连续且堆积在道夫前。经过抗静电处理的PA56纤维在梳理机各个位置的静电电势处于较低水平(≤+0.28 k V),能形成完整均匀的纤维网并且能连续地传递到储棉辊上形成棉卷。棉网出口处的静电释放能力是保证PA56成网质量的关键。PA56纤维梳理优化工艺为:锡林转速500 r/min,锡林、刺辊线速比2.4。展开更多
