快装锅炉的汽水分离装置,较多采用的是带小孔的干汽管或顶部斜孔板。蒸汽进入小孔向上流动时,携带的水滴靠重力和气流折返时的惯性力分离出来。为使分离出的水滴流回锅炉,干汽管底部均装有疏水管。可是,我们在工作中发现,有些锅炉的疏水管已经脱落,有的锅炉出厂时就没安装疏水? Fastener boiler soda separation device, the more the dry pipe with a small hole or the top inclined plate. When the steam enters the hole and flows upwards, the water droplets carried are separated by the force of inertia when returning to the air flow. In order to return the separated water droplets back to the boiler, the bottom of the dry steam pipe is equipped with a hydrophobic pipe. However, we found at work that some of the boiler’s drainpipes have fallen off, and some boilers are not installed with hydrophobicity when they leave the factory.
