为解决蒸发器的结垢问题,设计了一种自动清洗自然循环式高效节能蒸发器,其关键是能否在合理的加热温差下产生足以带动自动清洗螺旋扭带可靠自转的自然循环推动力,为此设计了一套中试装置.常压蒸发条件下的中试结果表明:在传热温差26℃时,自然循环推动力可达0.11MPa以上,传热系数可提高10%以上,能可靠地带动扭带自转实行连续地自动清洗,且该技术与现有蒸发生产工艺和加热蒸汽压力条件完全适应,使用推广后能为生产企业创造较高的效益.

A fouling-removal evaporator of natural circulation is developed to solve the fouling problem. The key lies in producing enough great driving force of natural circulation at reasonable heating temperature difference to make twisted tape self-rotate reliably in hear transfer tubes. Therefore, a new evaporator was produced in industry and trial experiments were conducted at normal pressure. It is showed that when temperature difference of heat transfer is only 26 ℃, the driving force of natural circulation can reach more than 11 000 Pa; the twis...
