Background
As a heat energy medium, the heat energy medium is widely applied to the industrial field, and in a steam thermodynamic system, steam forms condensed water after being subjected to heat exchange through heat exchange equipment and is discharged. The power steam is subjected to heat exchange by process equipment, and then condensed water is discharged, and low-pressure steam is usually mixed in the condensed water. The source of this portion of low pressure steam: secondary steam flashed in the pressure reduction process of the discharged condensed water; the steam trap bypass of part of the process equipment is opened, or the steam cascade caused by the leakage of the steam trap enters the condensate water. Therefore, most steam thermodynamic systems often recover a large amount of low pressure steam associated with the condensate. At present, no effective recovery method is available for low-pressure steam in condensed water, and the discharge of condensed water of process equipment is influenced by the increase of backpressure formed by the low-pressure steam, so that most of low-pressure steam can be directly discharged on site, and a large amount of heat energy is wasted.
