Abstract

The present application relates to a sealing soft water recovery apparatus for a vacuum pump in a vacuum pressure swing adsorption oxygen generation system, including a water tank, a wet Roots vacuum pump, a steam-water separator, and a collecting sink which are sequentially connected, where the collecting sink is connected to the water tank by a delivery tube provided with a delivery pump; and the water tank is connected to the wet Roots vacuum pump by a water inlet tube provided with a solenoid valve for controlling the opening and closing of a water channel. The present application has the effects of recovering sealing soft water and saving resources.
