用白水取代用于纸机成形部和压榨部喷水管的新鲜水具有巨大的经济效益。对幅宽9900mm的挂面纸板机上的喷水管进行了调研,并对每个喷水管利用白水的低、中、高风险进行了分类,详细研究了在这3个风险区域用白水取代新鲜水所节约的成本。研究发现,因为减少了对热水的需求,节能节约了350万美元,占到了3个风险区总节约成本(450万美元)的77.5%。此前,由于固/液分离技术的局限性,不能将白水回用到高风险区,如高压喷水管,但自引进了PetaxTM精细过滤系统后,节约了84.6万美元,约占总节约成本(450万美元)的19%。
Replacing fresh water used for paper machine forming and press section sprinklers with white water is a huge economic benefit. We investigated the sprinklers on the 9900mm breadboard machine and classified the low, medium and high risks of using white water for each sprinkler. We studied in detail the replacement of fresh water with white water in the three risk areas The cost savings. The study found savings of $ 3.5 million in energy savings due to the reduced need for hot water, accounting for 77.5% of the total cost savings ($ 4.5 million) in the three risk areas. Previously, due to the limitations of solid / liquid separation technology, white water could not be reused in high-risk areas such as high-pressure sprinklers but saved $ 846,000 after introducing the PetaxTM Fine Filtration System, accounting for the total cost savings 4.5 million) 19%.
