METHOD FOR AUTOMATICALLY DEGASSING CIRCULATED LIQUID USING WALL-FLOW VACUUM DEGASSING MACHINE

摘要

A method for automatically degassing circulated liquid using wall-flow vacuum degassing machine is provided. The wall-flow vacuum degassing machine comprises a fixing end (1), a pump connection end (2), a liquid level sensor port (3), a water inlet end (4), a built-in wall-flow spraying tube (5), a wall-flow nozzle (6), an air-discharging end (7), an air-discharging valve (8), a vacuum meter interface (9), a vacuum container (10), a wall-flow guide device (11) and a pollution-discharging end（12）. In which, the built-in wall-flow spraying tube (5) and the wall-flow nozzle (6) compose the built-in wall-flow ejector. The wall-flow nozzle (6) can be a single nozzle or multi nozzles (13). The wall-flow vacuum degassing machine is configured on a low-level backwater end of a liquid circulating system. The liquid flows in the built-in wall-flow spraying tube (5) and the wall-flow nozzle (6) and finally wall-flows along the vacuum container (10) depending on the self pressure of the system. The device degasses on the low-level of the liquid circumfluence, which can reduce the gas content during the liquid circulation and increase the effectiveness of liquid circulation effectively.
