上海市复建包装公司增产不忘节能,把原来弃而不用的蒸气热水回收利用,收到一举三得之功。该公司所属纸箱厂日耗筒纸50吨以上,其纸板生产线车间在加工瓦楞纸时,为提高产品质量,须将主楞棍加热。一天需10余吨蒸气作热源,但蒸气冷凝水长期以来来白白地随下水道排出,造成三大弊病。水资源被白白地消费掉;白耗热能,因蒸汽温度高达摄氏190℃左右,冷凝水温度亦达90℃左右;污染
Shanghai Rehabilitation Packaging Co., Ltd. has not forgotten to increase production by increasing energy consumption. It has recycled steam hot water, which was abandoned but not used, and has received three contributions. The company’s carton factory has more than 50 tons of daily paper consumption. When the paperboard production line workshop processes corrugated paper, it must heat the main crowbar in order to improve product quality. One day more than 10 tons of steam is needed as a heat source, but steam condensate has long been discharged in sewers in vain, causing three major maladies. Water resources are consumed in vain; white heat is consumed because the steam temperature is as high as about 190°C, and the condensate temperature is about 90°C.
