Description

Technical Field

[0001] The utility model relates to the technical field of pipeline equipment, in particular to a steam pipeline condensed water vapor-liquid separation and recovery mechanism. Background Art

[0002] The steam trap of the steam network discharges the condensed water in the pipe when it is in operation. During the process of steam trap drainage, the output hot water temperature is very high, reaching nearly 100 degrees. Steam will be mixed in the steam trap when it is closed. Especially in winter, the high-temperature hot water after discharge will also vaporize due to the low ambient temperature, causing steam in the steam network.

[0003] In the prior art, the utility model patent with application number CN202123107871.8 discloses a hydrophobic buffer and anti-gasification steam pipe network system, including a water outlet pipe and an anti-gasification device. The water outlet pipe is connected to the anti-gasification device. The anti-gasification device includes a storage box, a treatment box and a discharge pipe. The steam is converted into condensed water through the low-temperature treatment box to prevent the steam from affecting the roadside green belt. It is more effective for municipal pipelines buried underground, but for steam pipelines erected using aerial pipe corridors, since a large amount of coolant is required, the cooling water tank puts a heavy burden on the pipe corridor, and it is also inconvenient to add cooling water, and there is room for further improvement.
