Background
Steam is used as a heating medium and is widely applied to industrial production enterprises in various industries, hospitals, municipal administration, buildings and the like. As a distribution and conveying link of steam, condensed water and air are inevitably contained in a steam pipeline, and particularly, the phenomenon that the tail end of the steam pipeline contains the condensed water and the air is often more serious. The existence of the condensed water can cause water hammer and corrosion to the pipeline, and the existence of the air aggravates the corrosion degree and generates potential safety hazard. In addition, when the condensed water and the air enter the steam equipment, the heat exchange efficiency of the steam equipment is reduced, the service life of the steam equipment is shortened, the failure rate and the maintenance cost of the steam equipment are increased, and the operation effect of the production process and the operation effect of the steam equipment are also influenced.
The drainage and evacuation equipment at the tail end of the steam pipeline is used for discharging non-condensable gases such as condensed water and air at the tail end of the steam pipeline, reducing corrosion of the pipeline and the equipment, improving efficiency of steam equipment and playing a role in preventing water hammer.
