Abstract: The present application discloses a waste argon separation system capable of reducing emission of cryogenic waste argon. The waste argon separation system capable of reducing emission of cryogenic waste argon includes a valve bank, at least two adsorption towers, sewage discharge channels having at least the same number as the adsorption towers, a gas inlet component, and at least one argon reflux component. The valve bank includes a gas inlet valve, an analytic control valve, and at least two sewage discharge valves. The top of each of the adsorption towers is provided with an argon-rich gas outlet, and the argon-rich gas outlet at the top of each of the adsorption towers is connected to each other to form a regeneration channel. The argon-rich gas outlet at the top of each of the adsorption towers is further connected to an argon-rich gas outlet channel.

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.
